Chicago — The latest findings from the FELIX phase 1b/2 study confirm the efficacy of obecabtagene autoleucel (obe-cel/Auto1, Autolus Therapeutics) and establish the CD19-directed autologous chimeric antigen receptor (CAR) T-cell product as a standard-of-care therapy for adults with relapsed or refractory B-cell acute lymphoblastic leukemia (R/R B-ALL).

These findings also highlight the favorable impact of CAR T persistence on treatment outcomes, and suggest that consolidative stem cell transplant (SCT) in R/R B-ALL patients treated with obe-cel does not improve outcomes, Elias Jabbour, MD, of the University of Texas MD Anderson Cancer Center, Houston, reported at the American Society of Clinical Oncology (ASCO) annual meeting.

The overall complete remission or complete remission with incomplete count recovery rate was 78% among 127 patients enrolled in the open-label, single-arm study and infused with obe-cel. Among the 99 patients who responded, 18 proceeded to consolidative SCT while in remission, Dr. Jabbour said, noting that all 18 who received SCT were in minimal residual disease (MRD)–negative remission at the time of transplant.

Of those 18 patients, 10 had ongoing CAR T persistence prior to transplant, he said.

At median follow-up of 21.5 months, 40% of responders were in ongoing remission without the need for subsequent consolidation with SCT or other therapy, whereas SCT did not appear to improve outcomes.

The median event-free survival (EFS) after censoring for transplant was 11.9 months, and the 12-month EFS rate was 49.5%. Without censoring for transplant, the EFS and 12-month EFS rate were 9.0 months and 44%, respectively.

“I would like to highlight that the time to transplant was 100 days, and of those 18 patients, all in MRD-negative status ... 80% relapsed or died from transplant-related complications,” Dr. Jabbour said.

Median overall survival (OS) without censoring for transplant was 15.6 months, and the 12-month OS rate was 61.1%. After censoring for transplant, the median OS and 12-month OS rate 23.8 months 63.7%, respectively. The survival curves were fully overlapping, indicating that transplant did not improve OS outcomes.

“Furthermore, when you look at the EFS and [OS], both show a potential plateau for a long-term outcome, and this trend is similar to what was reported in a phase 1 trial with 2 years of follow up and more,” Dr. Jabbour said.

The investigators also assessed the impact of loss of CAR T-cell persistence and loss of B-cell aplasia and found that “both ongoing CAR T-cell persistence and ongoing B-cell aplasia, were correlated with better event-free survival,” he noted, explaining that the risk of relapse was 2.7 times greater in those who lost versus maintained CAR T-cell persistence, and 1.7 times greater in those who lost versus maintained B-cell aplasia.

Among those with ongoing remission at 6 months, median EFS was 15.1 months in those who lost CAR T-cell persistence, whereas the median EFS was not reached in those who maintained CAR T-cell persistence.

Obe-cel is an autologous CAR T-cell product with a fast off-rate CD19 binder designed to mitigate immunotoxicity and improve CAR T-cell expansion and persistence, Dr. Jabbour said, noting that pooled efficacy and safety results from the FELIX phase 1b and 2 trials of heavily pretreated patients have previously been reported.

The findings support the use of obe-cel as a standard treatment in this patient population, and demonstrate that ongoing CAR T-cell persistence and B-cell aplasia are associated with improved EFS — without further consolidation therapy after treatment, he concluded.

This study was funded by Autolus Therapeutics. Dr. Jabbour disclosed ties with Abbvie, Ascentage Pharma, Adaptive Biotechnologies, Amgen, Astellas Pharma, Bristol-Myers Squibb, Genentech, Incyte, Pfizer, and Takeda.

SAN DIEGO – Researchers are unraveling the complex relationship between cardiovascular (CV)- and stroke-related outcomes in migraine with, and without, aura.

Early results of one study suggest that aura increases the risk for major adverse cerebrovascular and CV events (MACE) in those with migraine, and that this risk is particularly high in men.

“We confirmed that aura increases the risk for these cerebrovascular and cardiovascular outcomes in people with migraine and that there’s an increased risk of these MACE events in men with migraine,” said study investigator Gina Dumkrieger, PhD, principal data science analyst and assistant professor of neurology, Mayo Clinic, Phoenix, Arizona.

The findings were presented at the annual meeting of the American Headache Society.
 

Few Data on Migraine and Stroke Risk

The extent to which migraine increases the risk for stroke CV outcomes has not been extensively studied.

“We’re trying to find out whether migraine-related factors make it more likely that you’re going to have one of these events,” said Dr. Dumkrieger. “Knowing a particular factor increases the risk is something patients and medical providers would want to know.”

Using Mayo Clinic electronic health records, which cover all three sites (Florida, Minnesota, and Arizona), researchers identified individuals with migraine using diagnostic codes. They also looked at data on sex, race, and the presence of aura.

They investigated whether a history of MACE risk factors — including atrial fibrillation, diabetes, hyperlipidemia, hypertension, and tobacco use — affected risk and the potential interaction of aura with these risk factors.

MACE events included cerebral infarction, intracerebral hemorrhage, and acute myocardial infarction.

The analysis included 130,126 participants (80% women, 95% White individuals). Of these, 6% experienced a MACE event, and 94% did not.

“We confirmed that aura does increase the risk for a MACE event, and all of the known risk factors that we included were also significant,” said Dr. Dumkrieger.

Odds ratios (ORs) were 3.82 for atrial fibrillation, 3.11 for hypertension, and 3.06 for hyperlipidemia.

It was surprising, said Dr. Dumkrieger, that male sex was tied to an increased risk for a MACE event (OR, 1.40). “This is not something that was known before,” she said.

The link between migraine and ischemic stroke, particularly with aura, was stronger in women — particularly young women.

Investigators also found an interaction between male sex and aura, when it comes to MACE outcomes, said Dr. Dumkrieger. “Males in general are at higher risk, and people with aura are at higher risk. Males with aura are also at higher risk, but maybe not as much as you would think they would be. It’s not a purely additive thing. This is something we need to look into more,” she said. 

The study also revealed an interaction between aura and hypertension as well as aura and tobacco use, but here too, it was not an additive risk, said Dr. Dumkrieger. However, she added, the presence of aura does not moderate the risk for hyperlipidemia, diabetes, or atrial fibrillation.

The research also showed a significant interaction between male sex and Black race which was additive. “There’s apparently increased risk if you are male and Black or African American that’s greater than what you would expect. We should be especially concerned about these individuals,” she said.
 

Unanswered Questions

The current analysis is part of a larger study that will more closely examine these relationships. “We want to learn, for example, why aura moderates some of the risk factors but not others,” said Dr. Dumkrieger.

The researchers also plan to investigate other migraine features, including headache frequency, and headache sensations such as pulsating or throbbing.

Dr. Dumkrieger was an investigator of another study, also presented at the AHS meeting, that’s investigating the role of migraine-specific features and imaging results in the complex interrelationship between migraine and MACE risk.

That study, which also used the Mayo Clinic electronic health record data, included 60,454 migraine patients diagnosed with migraine after 2010.

Researchers divided participants into those with a MACE outcome (1107) and those without such an outcome (59,347) after at least 2 years of follow-up. They created a propensity cohort of individuals matched for age and risk factors for MACE outcome.

The final cohort consisted of 575 patients with and 652 patients without MACE outcome.

One of the most interesting early results from this study was that those with a MACE outcome had significantly more white matter hyperintensities than those with no MACE outcome, at 64% versus 51%, respectively. 

This and other findings need to be validated in a different cohort with an electronic health records database from another institution. In future, the team plans to focus on identifying specific migraine features and medications and their relative contributions to MACE risk in migraine patients.

Yet another study featured at the AHS meeting confirmed the increased risk for stroke among migraine patients using a large database with over 410,000 subjects.

Results showed stroke was more than three times more common in those with a migraine diagnosis than in those without (risk ratio, [RR] 3.23; P < .001). The RR for hemorrhagic stroke (3.15) was comparable with that of ischemic stroke (3.20).

The overall stroke RR for chronic migraine versus controls without migraine was 3.68 (P < .001). The RR for migraine with aura versus migraine without aura was 1.37 (P < .001).
 

Useful Data

Commenting on the research, Juliana VanderPluym, MD, a headache specialist at the Mayo Clinic, Phoenix, Arizona, described this new information as “very useful.”

The fact that there are more white matter lesions on MRI scans in migraine patients with MACE needs further exploration, said Dr. VanderPluym.

“Understanding how much of that relates to migraine, how much relates to other comorbid conditions, and what this all means together, is very important, particularly because MACE can be life-threatening and life-altering,” she added.

Learning how migraine medications may impact MACE risk is also something that needs to be examined in greater depth, she said. “I would think that migraines that are controlled might have a different risk for MACE than uncontrolled migraine,” she said.

The investigators reported no relevant financial conflicts of interest.

The MUC-1 vaccine tecemotide plus standard neoadjuvant systemic therapy was shown to notably improve distant relapse-free survival and overall survival rates in breast cancer patients, in a new study.

“This is the first successful study of a breast cancer vaccine to date,” Christian F. Singer, MD, said during an interview. Dr. Singer, the lead author of the new study, presented the results during a poster session at the 2024 annual meeting of the American Society of Clinical Oncology (ASCO).

Previously known as both liposomal BLP25 and Stimuvax, tecemotide is an antigen-specific immunotherapy that targets the cancer therapy–resistant MUC-1 glycoprotein, which is overexpressed in over 90% of breast cancers. Tecemotide also has been shown to moderately improve overall survival rates in non–small cell lung cancer.

“We are not at all surprised by the results of this study in breast cancer,” Gregory T. Wurz, PhD, senior researcher at RCU Labs in Lincoln, California, said in an interview.

Dr. Wurz is coauthor of several studies on peptide vaccines, including a mouse model study of human MUC-1–expressing mammary tumors showing that tecemotide combined with letrozole had additive antitumor activity. Another paper he coauthored showed that ospemifene enhanced the immune response to tecemotide in both tumor-bearing and non–tumor-bearing mice. These findings, combined with other research, led to the creation of a patented method of combining therapies to enhance the efficacy of immunotherapy in the treatment of cancer and infectious diseases. Dr. Wurz was not involved in the new research that Dr. Singer presented at ASCO.
 

Study Methods and Results

Dr. Singer, head of obstetrics and gynecology at the Medical University of Vienna, Vienna, Austria, and coauthors randomized 400 patients with HER2-negative early breast cancer in a prospective, multicenter, two-arm, phase 2 ABCSG 34 trial to receive preoperative standard of care (SOC) neoadjuvant treatment with or without tecemotide.

Postmenopausal women with luminal A tumors were given 6 months of letrozole as SOC. Postmenopausal patients with triple-negative breast cancer, luminal B tumors, in whom chemotherapy was SOC, as well as all premenopausal study participants, were given four cycles of both epirubicin cyclophosphamide and docetaxel every 3 weeks.

The study’s primary endpoint was the residual cancer burden at the time of surgery.

Long-term outcomes were measured as part of a translational project, while distant relapse-free survival (DRFS) and overall survival (OS) were analyzed with Cox regression models. Long-term outcome data were available for 291 women, of whom 236 had received chemotherapy as SOC.

While tecemotide plus neoadjuvant SOC was not associated with a significant increase in residual cancer burden (RCB) at the time of surgery (36.4% vs 31.5%; P = .42; 40.5% vs 34.8%; P = .37 for the chemotherapy-only cohort), follow-up at 7 years showed 80.8% of patients who had received SOC plus tecemotide were still alive and free from metastasis.

In patients who had received SOC alone, the OS rate at 7 years with no metastasis was 64.7% (hazard ratio [HR] for DRFS, 0.53; 95% CI, 0.34-0.83; P = .005). The OS rate for the study group was 83.0% vs 68.2% in the non-tecemotide cohort (HR for OS, 0.53; 95% CI, 0.33-0.85; P = .008).

The lack of RCB signal at the endpoints, “tells us that pathologic complete response and residual cancer burden simply are not adequate endpoints for cancer vaccination studies and we need to find other predictive/prognostic markers, said Dr. Singer. “We are currently looking into this in exploratory studies.”

The chemotherapy plus tecemotide cohort had a notable outcome with a DRFS of 81.9% vs 65.0% in the SOC group (HR, 0.50; 95% CI, 0.31-0.83; P = .007), and an OS rate of 83.6% vs 67.8% (HR, 0.51; 95% CI, 0.30-0.88; P = .016).

Dr. Singer characterized the HRs as intriguing, saying that they “pave the way for new trials.”
 

Ideas for Further Study of Tecemotide

“What we would like to see next for tecemotide are clinical studies that explore whether immunomodulatory agents can further enhance the response to tecemotide in lung, breast, and potentially other MUC-1–expressing cancers,” Dr. Wurz said.

Future phase 3 studies of MUC-1 cancer vaccines, possibly those using mRNA technology, are yet to come, according to Dr. Singer. “We also need to find out why the vaccine works sometimes and sometimes not.”

Dr. Singer disclosed financial ties to AstraZeneca/MedImmune, Daiichi Sankyo Europe, Novartis, Gilead Sciences, Sanofi/Aventis, Amgen, Myriad Genetics, and Roche. Dr. Wurz had no disclosures, but his research partner and founder of RCU Labs, Michael De Gregorio, is the sole inventor of the patent referenced in the story. That patent has been assigned to the Regents of the University of California.

The MUC-1 vaccine tecemotide plus standard neoadjuvant systemic therapy was shown to notably improve distant relapse-free survival and overall survival rates in breast cancer patients, in a new study.

“This is the first successful study of a breast cancer vaccine to date,” Christian F. Singer, MD, said during an interview. Dr. Singer, the lead author of the new study, presented the results during a poster session at the 2024 annual meeting of the American Society of Clinical Oncology (ASCO).

Previously known as both liposomal BLP25 and Stimuvax, tecemotide is an antigen-specific immunotherapy that targets the cancer therapy–resistant MUC-1 glycoprotein, which is overexpressed in over 90% of breast cancers. Tecemotide also has been shown to moderately improve overall survival rates in non–small cell lung cancer.

“We are not at all surprised by the results of this study in breast cancer,” Gregory T. Wurz, PhD, senior researcher at RCU Labs in Lincoln, California, said in an interview.

Dr. Wurz is coauthor of several studies on peptide vaccines, including a mouse model study of human MUC-1–expressing mammary tumors showing that tecemotide combined with letrozole had additive antitumor activity. Another paper he coauthored showed that ospemifene enhanced the immune response to tecemotide in both tumor-bearing and non–tumor-bearing mice. These findings, combined with other research, led to the creation of a patented method of combining therapies to enhance the efficacy of immunotherapy in the treatment of cancer and infectious diseases. Dr. Wurz was not involved in the new research that Dr. Singer presented at ASCO.
 

Study Methods and Results

Dr. Singer, head of obstetrics and gynecology at the Medical University of Vienna, Vienna, Austria, and coauthors randomized 400 patients with HER2-negative early breast cancer in a prospective, multicenter, two-arm, phase 2 ABCSG 34 trial to receive preoperative standard of care (SOC) neoadjuvant treatment with or without tecemotide.

Postmenopausal women with luminal A tumors were given 6 months of letrozole as SOC. Postmenopausal patients with triple-negative breast cancer, luminal B tumors, in whom chemotherapy was SOC, as well as all premenopausal study participants, were given four cycles of both epirubicin cyclophosphamide and docetaxel every 3 weeks.

The study’s primary endpoint was the residual cancer burden at the time of surgery.

Long-term outcomes were measured as part of a translational project, while distant relapse-free survival (DRFS) and overall survival (OS) were analyzed with Cox regression models. Long-term outcome data were available for 291 women, of whom 236 had received chemotherapy as SOC.

While tecemotide plus neoadjuvant SOC was not associated with a significant increase in residual cancer burden (RCB) at the time of surgery (36.4% vs 31.5%; P = .42; 40.5% vs 34.8%; P = .37 for the chemotherapy-only cohort), follow-up at 7 years showed 80.8% of patients who had received SOC plus tecemotide were still alive and free from metastasis.

In patients who had received SOC alone, the OS rate at 7 years with no metastasis was 64.7% (hazard ratio [HR] for DRFS, 0.53; 95% CI, 0.34-0.83; P = .005). The OS rate for the study group was 83.0% vs 68.2% in the non-tecemotide cohort (HR for OS, 0.53; 95% CI, 0.33-0.85; P = .008).

Marstacimab, a novel, investigational monoclonal antibody, shows long-term safety and efficacy in the prevention of bleeding events in patients with hemophilia A as well as B without inhibitors, potentially adding to the toolbox for hemophilia A and representing a first of its kind therapy for hemophilia B.

“In the long-term extension study treatment with marstacimab demonstrates sustained or improved efficacy for treated and total annualized bleeding rates (ABR) in adults and adolescents with hemophilia A or hemophilia B in this data set of patients without inhibitors,” first author Shamsah Kazani, MD, of Pfizer, Cambridge, Massachusetts, said in presenting the findings at the 2024 annual meeting of the European Hematology Association (EHA) in Madrid.

“The majority of the patients from the pivotal study chose to transition into the long-term extension, and we are finding that these patients are highly compliant with their weekly marstacimab dose, with more than 98% compliance,” Dr. Kazani said.

Marstacimab targets the tissue factor pathway inhibitor, a natural anticoagulation protein that prevents the formation of blood clots, and is administered as a once-weekly subcutaneous injection.

The therapy has been granted fast-track and orphan drug status in the United States, in addition to orphan drug status in the European Union for the prevention of hemophilia bleeding episodes.

If approved, the therapy would become the first once-weekly subcutaneous therapy for either hemophilia A or B. Emicizumab, which also is administered subcutaneously, is only approved to prevent or reduce bleeding in hemophilia A.

The latest findings are from an interim analysis of a long-term extension study involving 107 of 116 patients who were in the non-inhibitor cohort in the pivotal BASIS trial. Data from that trial, involving patients aged 12-75 previously showed favorable outcomes in the non-inhibitor cohort receiving marstacimab, and a cohort of patients with inhibitors is ongoing.

Participants entering the extension study were continuing on 150-mg subcutaneous doses of marstacimab, which had been administered in the BASIS study for 12 months after a loading dose of 300 mg.

Of the patients, 89 (83%) were adult and 18 (17%) were adolescents. Overall, they had a mean age of 29 years; 83 (76%) patients had hemophilia A, while 24 (22.4%) had hemophilia B.

Prior to switching to marstacimab treatment, 32 patients had been treated with factor replacement therapy on demand, while 75 received the therapy as routine prophylaxis.

With a mean additional duration of follow-up of 12.5 months in the extension study (range, 1-23.1 months), the overall rate of compliance was very high, at 98.9%.

In the pivotal and extension studies combined, 21% of patients had their marstacimab dose increased from 150 mg to 300 mg weekly, which was an option if patients had 2 or more spontaneous bleeds in a major joint while on the 150-mg dose.

In the hemophilia A and B groups combined, those previously treated with on-demand factor replacement therapy (n = 33) had substantial reductions in estimated ABR for treated bleeds from the baseline of 38.0 prior to initiating marstacimab, to 3.2 after 12 months of the treatment in the trial (P < .001).That reduction was sustained at an ABR of 3.7 after the mean additional 12.5 months in the extension study.

The corresponding estimated ABR rates in the routine prophylaxis group (n = 83) were 7.9 at baseline, 5.1 at the end of the trial, and 2.8 in the extension study analysis interim cutoff.

The authors then further stratified the results based on hemophilia A or B groups: Among patients with hemophilia A (n = 26), the on-demand subgroup had a baseline ABR of 40.6, which dropped substantially to just 3.6 after 12 months on marstacimab in the pivotal trial and was sustained at 5.3 in the extension study.

Similar trends were observed in the hemophilia A group who received routine prophylaxis (n = 65), with an ABR of 9.2 at baseline; 5.3 after the trial, and 3.1 at the extension study interim.

The trends were similar among those with hemophilia B, albeit with lower numbers of patients, consistent with hemophilia B being more rare.

The mean ABR at baseline in the on-demand group of those patients (n = 7) was 28.7, which was reduced to just 1.7 after the 12-months of active marstacimab treatment and sustained at 1.8 by the interim analysis of the extension study.

Of hemophilia B patients previously on routine prophylaxis (n = 18), the mean ABR at baseline was 3.3 and was at 4.7 at the end of the trial. The rate declined to 2.3 in the extension phase.

“We see that these trends of improvement with marstacimab are sustained into the long-term extension study, both in the on-demand group and in the routine prophylaxis groups,” Dr. Kazani said.

Importantly, she noted that marstacimab continued to be well tolerated and safe in the long-term extension study, with no reports of thromboembolic events, which had been a concern with the drug.

Commenting on the study, Margaret Ragni, MD, MPH, a professor of medicine and clinical and translational research in the Division of Hematology/Oncology at the University of Pittsburgh, Pittsburgh, Pennsylvania, noted that marstacimab could represent an important addition in the prevention of bleeds in hemophilia. “[If marstacimab is approved], hemophilia B patients [will] have a drug that can be given subcutaneously weekly to rebalance hemostasis, reducing bleeds, just as hemophilia A patients have with emicizumab.”

Dr. Ragni underscored, however, that caveats include the important point that “neither [marstacimab nor emicizumab] treats bleeds. For that, standard factor replacement therapy or bypass for inhibitors, would be required.”

Also, “a limitation with marstacimab is the lack of weight-dependent dosing. All use one dose [however, in the studies they did use 150 mg or 300 mg]. ... Furthermore, emicizumab can be given weekly, biweekly, or monthly, while that [variation in dosing] is not yet studied with marstacimab.”

And while no thromboembolic events occurred during the trial, Dr. Ragni underscored that “longer-term follow-up is needed.”

The marstacimab long-term extension study is designed to extend to 7 years of follow-up.

The study was sponsored by Pfizer, and Dr. Kazani is an employee of Pfizer. Dr. Ragni reported no disclosures.

LYON, France – Lerodalcibep, a novel, third-generation anti-proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor, helps high-risk patients already receiving maximally tolerated statins to achieve guideline lipid targets, reported investigators.

In the randomized, placebo-controlled LIBerate-CVD trial of more than 900 patients, lerodalcibep led to reductions from baseline in low-density lipoprotein (LDL) cholesterol levels of more than 60%.

“We believe that lerodalcibep offers a novel, effective alternative to current PCSK9 inhibitors for patients with cardiovascular disease or at very high risk for cardiovascular disease,” said Evan Stein, MD, PhD, chief scientific officer and cofounder of LIB Therapeutics in Chicago, who presented the findings at the European Atherosclerosis Society (EAS) 2024.

Moreover, it leads to “substantial additional LDL cholesterol reductions on top of existing oral agents” and allows more than 90% of patients to achieve the latest European Society of Cardiology (ESC) guideline targets, he said.

Lerodalcibep has “tolerability and safety similar to placebo,” Dr. Stein said, and requires only “a small monthly injection, which takes about 12 seconds.”

“The drug doesn’t require refrigeration” and is “stable, so far, over 9 months,” he reported.

The latest data “confirm the efficacy of lerodalcibep,” said Giuseppe Danilo Norata, PhD, from the Department of Pharmacological and Biomolecular Sciences at the University of Milan, Milan, Italy, who was not involved in the study.

The LDL cholesterol reduction in this phase 3 trial is “in line with what was observed in LIBerate-FH,” and the high proportion of patients achieving their LDL cholesterol target is “impressive,” he added.
 

Effective and Well Tolerated

The safety results are “suggestive of a drug that is well tolerated, with injection-site reactions being the only remarkable adverse event increased in the treatment group,” Dr. Norata reported.

Only a “limited number” of patients developed neutralizing antidrug antibodies, which did not affect the efficacy of lerodalcibep. However, “given that the therapy is expected to be administered for years,” a longer analysis is needed to exclude the concern that a small percentage of neutralizing antidrug antibodies could reduce the efficacy, he said.

If approved, lerodalcibep could end up as a first-line option in the treatment pathway for high-risk cardiovascular disease because the efficacy “is similar to that of other injectable PCSK9 inhibitors,” he said, adding that its position in the market will “largely depend on the price.”

As the mechanism of action is similar to that of other monoclonal antibodies, “there is no pharmacological rationale to use it after another PSCK9 inhibitor,” he explained.

Lerodalcibep is a small recombinant fusion protein that combines a PCSK9-binding domain with human serum albumin.

The binding domain blocks the interaction between PCSK9 and the LDL cholesterol receptor, and the albumin linkage increases the half-life to 12-15 days, allowing low-volume injections to be given every 4 weeks.

A prior phase 2 study suggested that lerodalcibep substantially decreases LDL cholesterol levels in patients already taking maximally tolerated statins. The 300-mg dose was associated with an average reduction from baseline in LDL cholesterol levels of 77% over 12 weeks, whereas free PCSK9 levels decreased by 88%.

The current phase 3 study enrolled individuals at 65 centers in 100 countries who had or were at a very high risk for cardiovascular disease and who had an LDL cholesterol level of ≥ 1.8 mmol/L despite being on maximally tolerated statins.

Study participants were randomized in a 2:1 ratio to receive monthly subcutaneous lerodalcibep (n = 614) or placebo (n = 308) for 52 weeks and were assessed for the co-primary endpoints of the percentage change in LDL cholesterol levels from baseline to week 52 and the mean of levels at weeks 50 and 52.

The mean age was similar in the lerodalcibep and placebo groups (63.3 vs 64.5 years), as were the proportion of female (30% vs 30%) and White (80% vs 79%) participants.

The vast majority of participants in the lerodalcibep and placebo groups had a documented cardiovascular event (85.3% vs 86.4%) and were receiving secondary prevention, and 87% and 82%, respectively, were receiving a statin (any dose).

In a modified intention-to-treat analysis, the mean placebo-adjusted reduction in LDL cholesterol levels from baseline with lerodalcibep was 62% at week 52 (P < .0001), and the mean of levels at weeks 50 and 52 was 69.4% (P < .0001).

Similar results were seen in a per protocol analysis and an intention-to-treat analysis with imputation, which is a US Food and Drug Administration measure introduced in 2021 that assumes patients who discontinue the study treatment have an outcome similar to that in the placebo patients.

Moreover, 98.2% of patients in the lerodalcibep group achieved the ESC and European Atherosclerosis Society recommended reduction in LDL cholesterol levels of ≥ 50%, whereas only 8.8% in the placebo group did.
 

Hitting the LDL Cholesterol Target

More patients in the lerodalcibep group than in the placebo group achieved the LDL cholesterol target of < 1.4 mmol/L (95.3% vs 18.5%), and more patients in the lerodalcibep group achieved both that target and the ≥ 50% target (94.5% and 6.8%).

Lerodalcibep was also associated with significant reductions from baseline in levels of non–high-density lipoprotein (HDL) cholesterol, apolipoprotein B, very LDL cholesterol, and triglycerides, as well as an increase in HDL cholesterol levels (P < .0001 for all).

In terms of safety, lerodalcibep was associated with an adverse event rate leading to withdrawal similar to that seen with placebo (4.2% vs 3.6%), and 15.9% and 14.8% of patients, respectively, experienced at least one serious adverse event.

In-stent restenosis occurred more often in the lerodalcibep group than in the placebo group (5.4% vs 2.0%).

The study drug was associated with low levels of transient and sporadic antidrug antibodies and a low rate of neutralizing antidrug antibodies (0.9%), which were not associated with restenosis, a reduction in free PCSK9 levels, or the ability of lerodalcibep to lower LDL cholesterol levels.

LYON, France – Lerodalcibep, a novel, third-generation anti-proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor, helps high-risk patients already receiving maximally tolerated statins to achieve guideline lipid targets, reported investigators.

In the randomized, placebo-controlled LIBerate-CVD trial of more than 900 patients, lerodalcibep led to reductions from baseline in low-density lipoprotein (LDL) cholesterol levels of more than 60%.

“We believe that lerodalcibep offers a novel, effective alternative to current PCSK9 inhibitors for patients with cardiovascular disease or at very high risk for cardiovascular disease,” said Evan Stein, MD, PhD, chief scientific officer and cofounder of LIB Therapeutics in Chicago, who presented the findings at the European Atherosclerosis Society (EAS) 2024.

Moreover, it leads to “substantial additional LDL cholesterol reductions on top of existing oral agents” and allows more than 90% of patients to achieve the latest European Society of Cardiology (ESC) guideline targets, he said.

Lerodalcibep has “tolerability and safety similar to placebo,” Dr. Stein said, and requires only “a small monthly injection, which takes about 12 seconds.”

CHICAGO — Surgical resection is the standard of care for small colorectal liver metastases, but the results of a phase 3 trial reported at the American Society of Clinical Oncology (ASCO) 2024 annual meeting may prompt a change.

At nearly 30 months of follow-up, European investigators found no difference in overall and progression-free survival with thermal ablation instead of surgery, as well as better local control, fewer adverse events, shorter hospital stays, and no treatment-related deaths.

The benefit of thermal ablation was so substantial that the trial was stopped early with about 300 of the planned 600 patients randomized.

Numerous retrospective studies have compared the two approaches, and some have reported better survival with surgery. As a result, although a large number of lesions are amenable to either approach, “the majority of colorectal liver mets [are] still being” resected, said lead investigator and presenter Martijn R. Meijerink, MD, PhD, an interventional radiologist at the Amsterdam University Medical Center, Amsterdam, the Netherlands.

Dr. Meijerink said many of the previous reviews were unreliable due to selection bias because patients only had ablation if their lesions couldn’t be removed surgically. In contrast, all patients in the COLLISION trial were eligible for resection.

“Thermal ablation in experienced centers seems to be at least as good as surgical resection for small liver tumors.” Patients would benefit if it replaced surgery as the standard of care with no compromise in survival, Dr. Meijerink added.

The 296 COLLISION patients were treated at 14 centers in the Netherlands, Belgium, and Italy. They had no more than 12 liver lesions 3 cm or smaller with a median of two lesions. Participants were split equally between the ablation and surgical arms of the trial.

Almost half of the surgeries were laparoscopic, and nearly 60% of the ablations were percutaneous. Recent technological advances were used in the ablation cases, including software to confirm the complete eradication of targeted metastases.

At 28.8 months, there was no difference in overall survival between treatment arms (hazard ratio [HR], 1.051; P = .813) and no difference in local (HR, 0.817; P = .53) and distant (HR, 1.03; P = .836) progression-free survival. Local control — meaning treated lesions didn’t grow back — favored thermal ablation (HR, 0.092; P = .024).

The results held across number subgroup analyses, including by stage, molecular profile, and number of lesions.

“Interestingly, the majority of ablation site recurrences were somehow retreated, and most of them successfully, [while] the majority of resection plane recurrences were not retreated,” Dr. Meijerink said.

Patients with ablation vs surgery spent a median of 1 day vs 4 days in the hospital. Almost 20% of patients in the surgery group had grade 3/4 treatment-related adverse events vs 6% of those in the ablation group, which isn’t surprising, Dr. Meijerink said, because “the needle is less invasive than a knife.”

Three patients (2.1%) died of surgical complications, but there were no treatment-related deaths with ablation.

Major Kenneth Lee, MD, PhD, a gastrointestinal surgeon at the University of Pennsylvania, Philadelphia, who was the study discussant, emphasized the importance of gathering prospective data to compare the two approaches fairly.

“Ablation appears equivalent to resection for small, ideally located colorectal liver mets,” he said. Still, longer follow-up is needed to ensure that cure rates with ablation match those with surgery.

The study was funded by Medtronic-Covidien, a maker of thermal ablation equipment. Among other industry ties, Dr. Meijerink reported receiving honoraria and research funding from Medtronic and advising the company. Dr. Lee didn’t have any disclosures.

MONTREAL – Levels of neurofilament light chain (Nfl) may be a biomarker of chemotherapy-induced peripheral neurotoxicity (CIPN), new research suggests.

Investigators found Nfl levels increased in cancer patients following a first infusion of the medication paclitaxel and corresponded to neuropathy severity 6-12 months post-treatment, suggesting the blood protein may provide an early CIPN biomarker.

“Nfl after a single cycle could detect axonal degeneration,” said lead investigator Masarra Joda, a researcher and PhD candidate at the University of Sydney in Australia. She added that “quantification of Nfl may provide a clinically useful marker of emerging neurotoxicity in patients vulnerable to CIPN.”

The findings were presented at the Peripheral Nerve Society (PNS) 2024 annual meeting.
 

Common, Burdensome Side Effect

A common side effect of chemotherapy, CIPN manifests as sensory neuropathy and causes degeneration of the peripheral axons. A protein biomarker of axonal degeneration, Nfl has previously been investigated as a way of identifying patients at risk of CIPN.

The goal of the current study was to identify the potential link between Nfl with neurophysiological markers of axon degeneration in patients receiving the neurotoxin chemotherapy paclitaxel.

The study included 93 cancer patients. All were assessed at the beginning, middle, and end of treatment. CIPN was assessed using blood samples of Nfl and the Total Neuropathy Score (TNS), the Common Terminology Criteria for Adverse Events (CTCAE) neuropathy scale, and patient-reported measures using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire–Chemotherapy-Induced Peripheral Neuropathy Module (EORTC-CIPN20).

Axonal degeneration was measured with neurophysiological tests including sural nerve compound sensory action potential (CSAP) for the lower limbs, and sensory median nerve CSAP, as well as stimulus threshold testing, for the upper limbs. 

Almost all of study participants (97%) were female. The majority (66%) had breast cancer and 30% had gynecological cancer. Most (73%) were receiving a weekly regimen of paclitaxel, and the remainder were treated with taxanes plus platinum once every 3 weeks. By the end of treatment, 82% of the patients had developed CIPN, which was mild in 44% and moderate/severe in 38%. 

Nfl levels increased significantly from baseline to after the first dose of chemotherapy (P < .001), “highlighting that nerve damage occurs from the very beginning of treatment,” senior investigator Susanna Park, PhD, told this news organization. 

In addition, “patients with higher Nfl levels after a single paclitaxel treatment had greater neuropathy at the end of treatment (higher EORTC scores [P ≤ .026], and higher TNS scores [P ≤ .00]),” added Dr. Park, who is associate professor at the University of Sydney.

“Importantly, we also looked at long-term outcomes beyond the end of chemotherapy, because chronic neuropathy produces a significant burden in cancer survivors,” said Dr. Park. 

“Among a total of 44 patients who completed the 6- to 12-month post-treatment follow-up, NfL levels after a single treatment were linked to severity of nerve damage quantified with neurophysiological tests, and greater Nfl levels at mid-treatment were correlated with worse patient and neurologically graded neuropathy at 6-12 months.”

Dr. Park said the results suggest that NfL may provide a biomarker of long-term axon damage and that Nfl assays “may enable clinicians to evaluate the risk of long-term toxicity early during paclitaxel treatment to hopefully provide clinically significant information to guide better treatment titration.” 

Currently, she said, CIPN is a prominent cause of dose reduction and early chemotherapy cessation. 

“For example, in early breast cancer around 25% of patients experience a dose reduction due to the severity of neuropathy symptoms.” But, she said, “there is no standardized way of identifying which patients are at risk of long-term neuropathy and therefore, may benefit more from dose reduction. In this setting, a biomarker such as Nfl could provide oncologists with more information about the risk of long-term toxicity and take that into account in dose decision-making.” 

For some cancers, she added, there are multiple potential therapy options.

“A biomarker such as NfL could assist in determining risk-benefit profile in terms of switching to alternate therapies. However, further studies will be needed to fully define the utility of NfL as a biomarker of paclitaxel neuropathy.”

Commenting on the research for this news organization, Maryam Lustberg, MD, associate professor, director of the Center for Breast Cancer at Smilow Cancer Hospital and Yale Cancer Center, and chief of Breast Medical Oncology at Yale Cancer Center, in New Haven, Connecticut, said the study “builds on a body of work previously reported by others showing that neurofilament light chains as detected in the blood can be associated with early signs of neurotoxic injury.” 

She added that the research “is promising, since existing clinical and patient-reported measures tend to under-detect chemotherapy-induced neuropathy until more permanent injury might have occurred.” 

Dr. Lustberg, who is immediate past president of the Multinational Association of Supportive Care in Cancer, said future studies are needed before Nfl testing can be implemented in routine practice, but that “early detection will allow earlier initiation of supportive care strategies such as physical therapy and exercise, as well as dose modifications, which may be helpful for preventing permanent damage and improving quality of life.” 

The investigators and Dr. Lustberg report no relevant financial relationships.

MONTREAL – Levels of neurofilament light chain (Nfl) may be a biomarker of chemotherapy-induced peripheral neurotoxicity (CIPN), new research suggests.

Investigators found Nfl levels increased in cancer patients following a first infusion of the medication paclitaxel and corresponded to neuropathy severity 6-12 months post-treatment, suggesting the blood protein may provide an early CIPN biomarker.

“Nfl after a single cycle could detect axonal degeneration,” said lead investigator Masarra Joda, a researcher and PhD candidate at the University of Sydney in Australia. She added that “quantification of Nfl may provide a clinically useful marker of emerging neurotoxicity in patients vulnerable to CIPN.”

The findings were presented at the Peripheral Nerve Society (PNS) 2024 annual meeting.
 

Common, Burdensome Side Effect

A common side effect of chemotherapy, CIPN manifests as sensory neuropathy and causes degeneration of the peripheral axons. A protein biomarker of axonal degeneration, Nfl has previously been investigated as a way of identifying patients at risk of CIPN.

The goal of the current study was to identify the potential link between Nfl with neurophysiological markers of axon degeneration in patients receiving the neurotoxin chemotherapy paclitaxel.

The study included 93 cancer patients. All were assessed at the beginning, middle, and end of treatment. CIPN was assessed using blood samples of Nfl and the Total Neuropathy Score (TNS), the Common Terminology Criteria for Adverse Events (CTCAE) neuropathy scale, and patient-reported measures using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire–Chemotherapy-Induced Peripheral Neuropathy Module (EORTC-CIPN20).

Axonal degeneration was measured with neurophysiological tests including sural nerve compound sensory action potential (CSAP) for the lower limbs, and sensory median nerve CSAP, as well as stimulus threshold testing, for the upper limbs. 

Almost all of study participants (97%) were female. The majority (66%) had breast cancer and 30% had gynecological cancer. Most (73%) were receiving a weekly regimen of paclitaxel, and the remainder were treated with taxanes plus platinum once every 3 weeks. By the end of treatment, 82% of the patients had developed CIPN, which was mild in 44% and moderate/severe in 38%. 

Nfl levels increased significantly from baseline to after the first dose of chemotherapy (P < .001), “highlighting that nerve damage occurs from the very beginning of treatment,” senior investigator Susanna Park, PhD, told this news organization. 

In addition, “patients with higher Nfl levels after a single paclitaxel treatment had greater neuropathy at the end of treatment (higher EORTC scores [P ≤ .026], and higher TNS scores [P ≤ .00]),” added Dr. Park, who is associate professor at the University of Sydney.

“Importantly, we also looked at long-term outcomes beyond the end of chemotherapy, because chronic neuropathy produces a significant burden in cancer survivors,” said Dr. Park. 

“Among a total of 44 patients who completed the 6- to 12-month post-treatment follow-up, NfL levels after a single treatment were linked to severity of nerve damage quantified with neurophysiological tests, and greater Nfl levels at mid-treatment were correlated with worse patient and neurologically graded neuropathy at 6-12 months.”

Dr. Park said the results suggest that NfL may provide a biomarker of long-term axon damage and that Nfl assays “may enable clinicians to evaluate the risk of long-term toxicity early during paclitaxel treatment to hopefully provide clinically significant information to guide better treatment titration.” 

Currently, she said, CIPN is a prominent cause of dose reduction and early chemotherapy cessation. 

“For example, in early breast cancer around 25% of patients experience a dose reduction due to the severity of neuropathy symptoms.” But, she said, “there is no standardized way of identifying which patients are at risk of long-term neuropathy and therefore, may benefit more from dose reduction. In this setting, a biomarker such as Nfl could provide oncologists with more information about the risk of long-term toxicity and take that into account in dose decision-making.” 

For some cancers, she added, there are multiple potential therapy options.

“A biomarker such as NfL could assist in determining risk-benefit profile in terms of switching to alternate therapies. However, further studies will be needed to fully define the utility of NfL as a biomarker of paclitaxel neuropathy.”

A central aim of prostate cancer treatment is to prolong survival, but trials often overlook another key goal: Improving — or at least maintaining — quality of life (QoL).

The recent American Society of Clinical Oncology (ASCO) 2024 annual meeting dedicated a session to QoL outcomes in men with prostate cancer.

The trials explored the effects of treatment suspension or intensification on health-related QoL as well as interventions to manage side effects in different patient populations.

The first presentation focused on a post hoc analysis of the phase 3 EMBARK trial, which looked at the effect of suspending treatment on health-related QoL in men with nonmetastatic disease at a high risk for biochemical recurrence.

Earlier findings from the trial, presented at ESMO in 2023, showed enzalutamide alone or in combination with androgen deprivation therapy (ADT) was associated with a significant improvement in metastasis-free survival vs placebo plus leuprolide.

The initial trial randomized 1068 patients at a high risk for biochemical recurrence to these three treatment groups and suspended therapy at week 37 if prostate-specific antigen (PSA) levels fell below 0.2 ng/mL. Patients, however, were not randomized into the treatment suspension groups. Treatment resumed if PSA levels rose to ≥ 2.0 ng/mL in patients who had undergone radical prostatectomy or ≥ 5.0 ng/mL in those who had not had surgery.

The post hoc analysis, which assessed patient-reported QoL outcomes following treatment suspension at baseline and every 12 weeks until progression, found no meaningful changes in the worst pain in the past 24 hours, as measured by the Brief Pain Inventory–Short Form.

Patients also reported no meaningful changes in total and physical well-being scores on the Functional Assessment of Cancer Therapy–Prostate (FACT-P) and on the European Quality of Life Five-Dimensions (EuroQol-5D) visual analog scale score, as well as no meaningful changes in sexual activity and urinary and bowel symptoms, based on scores from the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire–Prostate 25 (QLQ-PR25).

Hormone treatment-related symptoms on the QLQ-PR25, however, “quickly improved but eventually began to worsen after week 97,” explained lead author Stephen J. Freedland, MD, from Cedars-Sinai Medical Center, Los Angeles, California, who presented the new findings at ASCO.

Dr. Freedland concluded that the EMBARK results show that enzalutamide, with or without ADT, improves metastasis-free survival vs leuprolide alone, without affecting global health-related QoL during treatment or after treatment suspension.

However, Channing J. Paller, MD, of the Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins Medicine, Baltimore, Maryland, who was not involved in the research, pointed out that “patient selection is key” when choosing therapies, given that ADT has distinct adverse effects. Comorbidities and adverse effects “must be taken into consideration to help the doctor and patient make more personalized treatment choices.”
 

Treatment Intensification and QoL

Another presentation explored health-related QoL outcomes from the phase 3 PRESTO trial.

The study examined ADT intensification in 504 patients who had high-risk biochemically relapsed nonmetastatic hormone-sensitive prostate cancer and a PSA doubling time of 9 months or less. Patients were randomized to ADT monotherapy with degarelix or leuprolide, ADT plus apalutamide, or ADT plus apalutamide, abiraterone acetate, and prednisone.

In previous data from PRESTO, the combination therapy groups both had significantly longer median PSA progression-free survival than the ADT monotherapy arm.

The latest data looked at the health-related QoL outcomes in the PRESTO population, measured using the Expanded Prostate Cancer Index Composite, the PROMIS Fatigue tool, the Hot Flash Related Daily Interference Scale, and the EuroQol-5D.

Ronald C. Chen, MD, MPH, of the University of Kansas Medical Center, Kansas City, who presented the new findings at ASCO, reported that ADT plus apalutamide improved PSA progression-free survival over ADT alone and did not meaningfully increase common treatment-related symptoms, such as hormonal symptoms, sexual dysfunction, hot flash interference, and fatigue.

However, treatment intensification with triple androgen regimen did not lead to further improvements in PSA progression-free survival but did increase the rate of serious adverse events, the time to testosterone recover, and increased hot flash interference.

PRESTO as well as EMBARK “provide a strong rationale for intensification of androgen blockade in men with high-risk biochemical recurrence after completing primary local therapy” and could even “reduce the need for subsequent treatment,” concluded Dr. Chen.
 

CBT for Managing ADT Side Effects

Up to 80% of men receiving ADT to treat prostate cancer experience night sweats and hot flashes, which are associated with sleep disturbance, anxiety, low mood, and cognitive impairments.

A third trial presented during the session looked at the impact of cognitive-behavioral therapy (CBT) on these side effects of ADT treatment.

Initial findings from the MANCAN study found that CBT delivered by a psychologist reduced the impact of hot flashes and night sweats at 6 weeks.

The MANCAN2 study assessed QoL at 6 months among 162 patients with localized or advanced prostate cancer who underwent at least 6 months of continuous ADT and who experienced more severe hot flashes and night sweats, defined as a score of ≥ 2 on the hot flashes and night sweats problem rating scale.

Study participants were randomized to CBT plus treatment as usual, or treatment as usual alone, with the intervention consisting of two CBT group sessions 4 weeks apart. Between CBT sessions, patients could refer to a booklet and CD, alongside exercises and CBT strategies.

MANCAN2 confirmed that CBT was associated with a significantly greater reduction in hot flash and night sweat scores over standard care alone at 6 weeks. Patients receiving CBT also reported better QoL, sleep, and functional status but those differences did not reach statistical significance.

By 6 months, those in the CBT group still reported better outcomes in each category, but no differences were statistically significant at this time point. Overall, however, 14% of treatment as usual alone patients discontinued ADT at 6 months vs none in the CBT arm.

“Further research is therefore needed to determine whether or not you can make this effect more durable” and to look at “the potential for CBT to support treatment compliance,” said study presenter Simon J. Crabb, PhD, MBBS, from the University of Southampton and University Hospital Southampton NHS Foundation Trust, Southampton, England.
 

QoL With Radioligand Crossover

Finally, the phase 3 PSMAfore study compared ¹⁷⁷Lu-PSMA-617 with abiraterone or enzalutamide in 468 taxane-naive patients with metastatic castration-resistant prostate cancer who had progressed on a previous androgen receptor pathway inhibitor.

In earlier analyses, Karim Fizazi, MD, PhD, Institut Gustave Roussy, Université Paris-Saclay, Paris, France, reported that ¹⁷⁷Lu-PSMA-617 improved radiographic progression-free survival by 59% over androgen receptor pathway inhibitor therapy but did not lead to significant differences in overall survival.

In a new interim analysis, Dr. Fizazi and colleagues explored outcomes in patients eligible to cross over to ¹⁷⁷Lu-PSMA-617 following androgen receptor pathway inhibitor therapy. Assessments of health-related QoL revealed that ¹⁷⁷Lu-PSMA-617 led to about a 40% improvement in scores on two QoL tools — 41% with FACT-P and 39% with EuroQol-5D.

On subscales of FACT-P, Dr. Fizazi reported that ¹⁷⁷Lu-PSMA-617 was also associated with a significantly longer time to worsening in physical, functional, and emotional well-being over standard therapy. A pain inventory score indicated that ¹⁷⁷Lu-PSMA-617 led to a 31% improvement in the time to worsening pain intensity, as well as a 33% increase in the time to worsening pain interference.

With the treatment having a “favorable safety profile,” Dr. Fizazi said the results suggest ¹⁷⁷Lu-PSMA-617 is a “treatment option” for patients with metastatic castration-resistant prostate cancer who have undergone androgen receptor pathway inhibitor treatment.

MANCAN2 was funded by the UK National Institute for Health and Care Research. EMBARK was funded by Astellas Pharma and Pfizer, the codevelopers of enzalutamide. PRESTO was funded by Alliance Foundation Trials and Johnson & Johnson. PSMAfore was funded by Novartis. Dr. Freedland declared relationships with Pfizer and Astellas Pharma, among others. Paller declared relationships with AstraZeneca, Dendreon, Exelixis, Janssen Oncology, Omnitura, Lilly, and Bayer. Dr. Chen declared relationships with Astellas Pharma, Pfizer, and others. Dr. Crabb declared relationships with AstraZeneca, Bristol-Myers Squibb, Ipsen, Merck, Amgen, Amphista Therapeutics, Bayer, Janssen, MSD, Pfizer, Astex Pharmaceuticals, Clovis Oncology, and Roche. Dr. Fizazi reported relationships with Novartis, AstraZeneca, and a dozen other companies.

Study participants were randomized to CBT plus treatment as usual, or treatment as usual alone, with the intervention consisting of two CBT group sessions 4 weeks apart. Between CBT sessions, patients could refer to a booklet and CD, alongside exercises and CBT strategies.

MANCAN2 confirmed that CBT was associated with a significantly greater reduction in hot flash and night sweat scores over standard care alone at 6 weeks. Patients receiving CBT also reported better QoL, sleep, and functional status but those differences did not reach statistical significance.

By 6 months, those in the CBT group still reported better outcomes in each category, but no differences were statistically significant at this time point. Overall, however, 14% of treatment as usual alone patients discontinued ADT at 6 months vs none in the CBT arm.

“Further research is therefore needed to determine whether or not you can make this effect more durable” and to look at “the potential for CBT to support treatment compliance,” said study presenter Simon J. Crabb, PhD, MBBS, from the University of Southampton and University Hospital Southampton NHS Foundation Trust, Southampton, England.
 

QoL With Radioligand Crossover

Finally, the phase 3 PSMAfore study compared ¹⁷⁷Lu-PSMA-617 with abiraterone or enzalutamide in 468 taxane-naive patients with metastatic castration-resistant prostate cancer who had progressed on a previous androgen receptor pathway inhibitor.

In earlier analyses, Karim Fizazi, MD, PhD, Institut Gustave Roussy, Université Paris-Saclay, Paris, France, reported that ¹⁷⁷Lu-PSMA-617 improved radiographic progression-free survival by 59% over androgen receptor pathway inhibitor therapy but did not lead to significant differences in overall survival.

In a new interim analysis, Dr. Fizazi and colleagues explored outcomes in patients eligible to cross over to ¹⁷⁷Lu-PSMA-617 following androgen receptor pathway inhibitor therapy. Assessments of health-related QoL revealed that ¹⁷⁷Lu-PSMA-617 led to about a 40% improvement in scores on two QoL tools — 41% with FACT-P and 39% with EuroQol-5D.

On subscales of FACT-P, Dr. Fizazi reported that ¹⁷⁷Lu-PSMA-617 was also associated with a significantly longer time to worsening in physical, functional, and emotional well-being over standard therapy. A pain inventory score indicated that ¹⁷⁷Lu-PSMA-617 led to a 31% improvement in the time to worsening pain intensity, as well as a 33% increase in the time to worsening pain interference.

With the treatment having a “favorable safety profile,” Dr. Fizazi said the results suggest ¹⁷⁷Lu-PSMA-617 is a “treatment option” for patients with metastatic castration-resistant prostate cancer who have undergone androgen receptor pathway inhibitor treatment.

MANCAN2 was funded by the UK National Institute for Health and Care Research. EMBARK was funded by Astellas Pharma and Pfizer, the codevelopers of enzalutamide. PRESTO was funded by Alliance Foundation Trials and Johnson & Johnson. PSMAfore was funded by Novartis. Dr. Freedland declared relationships with Pfizer and Astellas Pharma, among others.

Findings from the phase 3 ESOPEC trial demonstrate an overall survival advantage with a perioperative chemotherapy regimen known as FLOT, compared with a neoadjuvant chemoradiation approach, called CROSS, in patients with resectable, locally advanced esophageal adenocarcinoma.

The study results, presented as a late-breaking abstract at the annual meeting of the American Society of Clinical Oncology (ASCO), help settle a long-standing debate about whether chemotherapy with FLOT — 5-florouracil, leucovorin, oxaliplatin, and docetaxel — before and after surgery, or neoadjuvant radiation plus CROSS — carboplatin and paclitaxel — followed by surgery is the best approach.

There has been “considerable disagreement as to whether giving all adjuvant therapy upfront versus ‘sandwich’ adjuvant therapy before and after surgery is the better standard of care for locally advanced resectable esophageal cancer,” Jennifer Tseng, MD, of Boston Medical Center, Boston, said in an ASCO press release. This randomized clinical trial shows the sandwich approach “provides better outcomes.”

The practice-changing ESOPEC findings will have an important effect on the management of patients with resectable esophageal adenocarcinoma and gastroesophageal junction adenocarcinoma, but local and distant failures remain a challenge in this population, explained invited discussant Karyn A. Goodman, MD.

Advances since the initiation of ESOPEC — such as immunotherapy options and personalized strategies — suggest the esophageal adenocarcinoma story is still evolving, said Dr. Goodman, professor and vice chair of research and quality in the Department of Radiation Oncology at Icahn School of Medicine at Mount Sinai, New York. 
 

The ESOPEC trial

Both the FLOT and CROSS regimens are established standards of care in resectable esophageal adenocarcinoma, and the choice of treatment has largely varied based on geographical location.

The current randomized, prospective, open-label ESOPEC trial, however, demonstrated that FLOT can prolong overall survival, first author Jens Hoeppner, MD, from the University of Bielefeld in Detmold, Germany, reported.

Overall, 438 patients with locally advanced, resectable esophageal adenocarcinoma recruited between February 2016 and April 2020 from 25 sites in Germany and randomized to either FLOT (n = 221) or CROSS (n = 217). The median age was 63 years, and most (89.3%) were men. Patients were followed until November 2023, and median follow-up was 55 months.

Patients in the FLOT arm received four cycles — one every 2 weeks for 8 weeks — followed by surgery 4-6 weeks later. FLOT cycles were reinitiated 4-6 weeks after surgery and given every 2 weeks for 8 weeks.

Those in the CROSS arm received one cycle per week of radiation therapy for 5 weeks plus carboplatin and paclitaxel followed by surgery 4-6 weeks after the last cycle.

Overall, 86% received both neoadjuvant therapy and surgery in the FLOT arm versus 82.9% in the CROSS group. Among these patients, 16.8% in the FLOT group achieved a pathological complete remission versus 10.0% in the CROSS arm.

In the intention-to-treat population, median overall survival was almost twice as long in the FLOT group — 66 months versus 37 months. At 3 years, those who received FLOT had a 30% lower risk of dying (hazard ratio [HR], 0.70), with 57.4% of patients alive at that point, compared with 50.7% patients in the CROSS arm.

The 5-year overall survival was 50.6% in the FLOT group versus 38.7% in the CROSS group.

Patients receiving FLOT also demonstrated improved progression-free survival (PFS), with a median PFS of 38 months versus 16 months. The 3-year PFS was 51.6% with FLOT versus 35.0% with CROSS (HR, 0.66). The exploratory subgroup analyses for sex, age, ECOG status, and clinical T and N stages also favored FLOT.

The 30-day postoperative mortality was 1.0% in the FLOT group and 1.7% in the CROSS group, and the 90-day postoperative mortality rate was 3.2% and 5.6%, respectively.

Based on these findings, perioperative chemotherapy with FLOT should be preferred over neoadjuvant chemoradiation with CROSS, Dr. Hoeppner concluded.

Dr. Goodman agreed, noting that, in the wake of ESOPEC, FLOT will likely be adopted as a more standard approach in the United States for patients who are fit. And, for patients who are not candidates for FLOT, CROSS is a reasonable option, she said.

But, she asked, does it really have to be an either/or situation?

Multiple studies, including Dr. Goodman’s 2021 Alliance/CALGB 80803 study, have demonstrated promising outcomes with combined modalities and adapting therapy based on treatment response. Several trials, for instance, are evaluating combining FLOT and CROSS, with some showing the approach is feasible and comes with manageable toxicity.

It’s also important to look outside of FLOT and CROSS. During ESOPEC, new approaches entered the treatment landscape, including the use of adjuvant immunotherapy following neoadjuvant chemoradiation and surgery for noncomplete response.

Take the CheckMate 577 study, which found that adjuvant nivolumab immunotherapy after preoperative CROSS and surgery significantly reduced metastatic recurrence and doubled disease-free survival in patients who did not achieve a complete response. This approach is now a standard of care for those patients.

FLOT plus neoadjuvant nivolumab may also be a viable option, Dr. Goodman noted, but we haven’t yet seen “any benefit in survival with the combo of chemotherapy and immunotherapy for resectable esophago-gastric cancer.”

Further studies are needed to evaluate the synergy of immunotherapy and radiotherapy. The next chapter of the esophageal adenocarcinoma story may feature a “best-of-both-worlds” approach that combines induction chemotherapy, followed by personalized chemoradiation, surgery, and potentially adjuvant immunotherapy, Dr. Goodman explained.

While the ESOPEC findings are impressive, the 5-year overall survival of only 50% is still suboptimal, she noted. “Given the poor prognosis with this disease, we need to continue to develop clinical trials to identify better targets, novel treatment combinations, and select patients that will respond best to specific treatment.”

ESOPEC was funded by the Deutsche Forschungsgemeinschaft (German Research Foundation). Dr. Hoeppner reported receiving travel, accommodations, and expenses from Intuitive Surgical. Dr. Goodman reported a relationship with the National Cancer Institute and consulting or advisory roles for Novartis, Philips Healthcare, RenovoRX, and Roche/Genentech.

VIENNA – The use of immunosuppressive and antifibrotic drugs to treat skin and lung fibrosis leads updated recommendations from the European Alliance of Associations for Rheumatology (EULAR) for the treatment of systemic sclerosis.

“The most impactful new recommendation relates to the evidence for immunosuppressive agents and antifibrotics for the treatment of skin fibrosis and lung fibrosis,” said Francesco Del Galdo, MD, PhD, professor of experimental medicine, consultant rheumatologist, and scleroderma and connective tissue diseases specialist at Leeds Teaching Hospitals NHS Trust, Leeds, England. Dr. Del Galdo presented the update at the annual European Congress of Rheumatology.

“But there are also new recommendations, including a redefined target population for hematopoietic stem cell transplantation following cyclophosphamide, the upfront combination treatment at the time of diagnosis of pulmonary arterial hypertension [PAH], and a negative recommendation for the use of anticoagulants for pulmonary arterial hypertension,” noted Dr. Del Galdo, highlighting key updates in the 2024 recommendations.

Robert B.M. Landewé, MD, PhD, professor and rheumatologist at Amsterdam University Medical Center, Amsterdam, the Netherlands, and Zuyderland Medical Center, Heerlen, the Netherlands, co-moderated the session on EULAR recommendations. “The management of systemic sclerosis is a field in which a lot is happening,” he said. “The last update goes back to 2017, and in the meantime, many new approaches have seen the light, especially pertaining to skin fibrosis and interstitial lung disease. Six new recommendations have been coined, covering drugs like mycophenolate mofetil, nintedanib, rituximab, and tocilizumab. None of these therapies were present in the 2017 recommendations. It seems the field is now ready to further expand on targeted therapies for the management of musculoskeletal and gastrointestinal manifestations, calcinosis, and the local management of digital ulcers.”
 

‘Therapeutic Continuums’ Aid Disease Management

Dr. Del Galdo and his colleagues grouped the various interventions across what the recommendations label as evidence-backed “therapeutic continuums.” These span six of the eight different clinical manifestations of systemic sclerosis: Raynaud’s phenomenon, digital ulcers, pulmonary hypertension, musculoskeletal manifestations, skin fibrosis, interstitial lung disease (ILD), and gastrointestinal and renal crisis.

A slide showing the different strengths of evidence for various drugs across the eight manifestations illustrated the principle behind the therapeutic continuums. “These ‘therapeutic continuums’ suggest a common pathogenetic mechanism driving the various manifestations of disease,” said Dr. Del Galdo. For example, he noted, “If rituximab had a positive response in skin and in lung, it suggests that B cells play a role in the clinical manifestations of skin and lung in this disease.”

Dr. Del Galdo highlighted the new immunosuppression continuum and associated treatments for skin and lung fibrosis. “For skin involvement, the task force recommended mycophenolate, methotrexate, and rituximab, with tocilizumab having a lower level of evidence and lower recommendation strength; similarly, in interstitial lung disease, we have rituximab, mycophenolate, cyclophosphamide, and nintedanib, and these all have the highest strength of evidence. Tocilizumab is assigned one strength of evidence below the other drugs.”

He also cited the phosphodiesterase 5 inhibitor (PDE5i) drugs that are used across Raynaud’s phenomenon, digital ulcers, and pulmonary arterial hypertension, which together form a vascular therapeutic continuum.

The complexity of systemic sclerosis and multiple manifestations was a major determinant of the recommendations, Dr. Del Galdo pointed out. “The task force realized that since this is such a complex disease, we cannot recommend one treatment unconditionally. For example, with mycophenolate mofetil, what works for most patients for the skin and lung manifestations might not for someone who experiences severe diarrhea, in which mycophenolate is contraindicated. So, the highest degree of recommendation that the task force felt comfortable with was ‘should be considered.’ ”

Dr. Del Galdo stressed that the complex nature of systemic sclerosis means that “when thinking of treating one manifestation, you also always need to consider all the other clinical manifestations as experienced by the patient, and it is this multifaceted scenario that will ultimately lead to your final choice.”

Turning to new evidence around drug use, Dr. Del Galdo said that rituximab has the highest level of evidence across skin and lung manifestations, nintedanib is new in lung, and tocilizumab is new across both skin and lung.

To treat systemic sclerosis–pulmonary arterial hypertension (SSc-PAH), as long as there are no contraindications, the task force recommends using PDE5i and endothelin receptor antagonists (ERAs) at diagnosis. Data from phase 3 trials show a better outcome when the combination is established early.

The task force suggests avoiding the use of warfarin in PAH. “This is supported by a signal from two trials showing an increase in morbidity and mortality in these patients,” noted Dr. Del Galdo.

He also pointed out that selexipag and riociguat were new and important second-line additions for the treatment of PAH, and — consistent with the ERA approach — the EULAR recommendation supports frequent follow-up to establish a treat-to-target approach to maximizing clinical outcomes in SSc-PAH and SSc-ILD. “Specifically, for the first time, we recommend monitoring the effect of any chosen intervention selected within 3-6 months of starting. The evidence suggests there is a group of patients who respond and some who respond less well and who might benefit from a second-line intervention.”

For example, results of one trial support the approach of adding an antifibrotic agent to reduce progression in people with progressive lung fibrosis. “Similarly, for pulmonary hypertension, we recommend putting patients on dual treatment, and if this fails, place them on selexipag or switch the PDE5i to riociguat,” Dr. Del Galdo said.
 

Systemic Sclerosis Research Agenda and Recommendations Align

Dr. Del Galdo highlighted the value of therapeutic continuums in advancing disease understanding. “It is starting to teach us what we know and what we don’t and where do we need to build more evidence. Effectively, they determine where the gaps in therapy lie, and this starts to guide the research agenda.

“In fact, what is really interesting about this recommendation update — certainly from the perspective of disease understanding — is that we are starting to have a bird’s-eye view of the clinical manifestations of scleroderma that have so often been dealt with separately. Now we are starting to build a cumulative evidence map of this disease.”

In 2017, the research agenda largely advocated identifying immune-targeting drugs for skin and lung fibrosis, Dr. Del Galdo pointed out. “Now, we’ve done that — we’ve identified appropriate immunosuppressive drugs — and this is testimony to the importance of these recommendations because what prioritized the research agenda 10 years ago ended up informing the clinical trials and made it into the recommendations.”

“We definitely are one step forward compared to this 2017 recommendation and closer to what we would like to do,” he asserted.
 

Remission Elusive but Getting Closer

In some respects, according to Dr. Del Galdo, research and development is making relatively slow progress, especially compared with other rheumatologic diseases such as rheumatoid arthritis. “We cannot put patients with systemic sclerosis in remission yet. But I think we are one step ahead in that we’ve now established the treat-to-target approach to maximize the efficacy with which we can stall disease progression, but we cannot yet put these patients into remission,” he said. Systemic sclerosis has multiple manifestations, and fibrotic damage cannot be reversed. “Right now, the scar will remain there forever,” he noted.

Until remission is achievable, Dr. Del Galdo advises diagnosing and treating patients earlier to prevent fibrotic manifestations.

Dr. Del Galdo explained the three leading priorities on the systemic sclerosis research agenda. “There are three because it is such a complex disease. The first is considering the patient voice — this is the most important one, and the patients say they want a more holistic approach — so trialing and treating multiple manifestations together.”

Second, Dr. Del Galdo said, he would like to see a patient-reported measure developed that can capture the entire disease.

Third, from a physician’s point of view, Dr. Del Galdo said, “We want to send the patients into remission. We need to continue to further deconvolute the clinical manifestations and find the bottleneck at the beginning of the natural history of disease.

“If we can find a drug that is effective very early on, before the patients start getting the eight different manifestations with different levels of severity, then we will be on the right road, which we hope will end in remission.”

Dr. Del Galdo has served on the speakers bureau for AstraZeneca and Janssen; consulted for AstraZeneca, Boehringer Ingelheim, Capella, Chemomab, Janssen, and Mitsubishi-Tanabe; and received grant or research support from AbbVie, AstraZeneca, Boheringer Ingelheim, Capella, Chemomab, Kymab, Janssen, and Mitsubishi-Tanabe. Dr. Landewé had no relevant disclosures.

For example, he noted, “If rituximab had a positive response in skin and in lung, it suggests that B cells play a role in the clinical manifestations of skin and lung in this disease.”

Dr. Del Galdo highlighted the new immunosuppression continuum and associated treatments for skin and lung fibrosis. “For skin involvement, the task force recommended mycophenolate, methotrexate, and rituximab, with tocilizumab having a lower level of evidence and lower recommendation strength; similarly, in interstitial lung disease, we have rituximab, mycophenolate, cyclophosphamide, and nintedanib, and these all have the highest strength of evidence. Tocilizumab is assigned one strength of evidence below the other drugs.”

He also cited the phosphodiesterase 5 inhibitor (PDE5i) drugs that are used across Raynaud’s phenomenon, digital ulcers, and pulmonary arterial hypertension, which together form a vascular therapeutic continuum.

The complexity of systemic sclerosis and multiple manifestations was a major determinant of the recommendations, Dr. Del Galdo pointed out. “The task force realized that since this is such a complex disease, we cannot recommend one treatment unconditionally. For example, with mycophenolate mofetil, what works for most patients for the skin and lung manifestations might not for someone who experiences severe diarrhea, in which mycophenolate is contraindicated. So, the highest degree of recommendation that the task force felt comfortable with was ‘should be considered.’ ”

Dr. Del Galdo stressed that the complex nature of systemic sclerosis means that “when thinking of treating one manifestation, you also always need to consider all the other clinical manifestations as experienced by the patient, and it is this multifaceted scenario that will ultimately lead to your final choice.”

Turning to new evidence around drug use, Dr. Del Galdo said that rituximab has the highest level of evidence across skin and lung manifestations, nintedanib is new in lung, and tocilizumab is new across both skin and lung.

To treat systemic sclerosis–pulmonary arterial hypertension (SSc-PAH), as long as there are no contraindications, the task force recommends using PDE5i and endothelin receptor antagonists (ERAs) at diagnosis. Data from phase 3 trials show a better outcome when the combination is established early.

The task force suggests avoiding the use of warfarin in PAH. “This is supported by a signal from two trials showing an increase in morbidity and mortality in these patients,” noted Dr. Del Galdo.

He also pointed out that selexipag and riociguat were new and important second-line additions for the treatment of PAH, and — consistent with the ERA approach — the EULAR recommendation supports frequent follow-up to establish a treat-to-target approach to maximizing clinical outcomes in SSc-PAH and SSc-ILD. “Specifically, for the first time, we recommend monitoring the effect of any chosen intervention selected within 3-6 months of starting. The evidence suggests there is a group of patients who respond and some who respond less well and who might benefit from a second-line intervention.”

For example, results of one trial support the approach of adding an antifibrotic agent to reduce progression in people with progressive lung fibrosis. “Similarly, for pulmonary hypertension, we recommend putting patients on dual treatment, and if this fails, place them on selexipag or switch the PDE5i to riociguat,” Dr. Del Galdo said.
 

Systemic Sclerosis Research Agenda and Recommendations Align

Dr. Del Galdo highlighted the value of therapeutic continuums in advancing disease understanding. “It is starting to teach us what we know and what we don’t and where do we need to build more evidence. Effectively, they determine where the gaps in therapy lie, and this starts to guide the research agenda.

“In fact, what is really interesting about this recommendation update — certainly from the perspective of disease understanding — is that we are starting to have a bird’s-eye view of the clinical manifestations of scleroderma that have so often been dealt with separately. Now we are starting to build a cumulative evidence map of this disease.”

In 2017, the research agenda largely advocated identifying immune-targeting drugs for skin and lung fibrosis, Dr. Del Galdo pointed out. “Now, we’ve done that — we’ve identified appropriate immunosuppressive drugs — and this is testimony to the importance of these recommendations because what prioritized the research agenda 10 years ago ended up informing the clinical trials and made it into the recommendations.”

“We definitely are one step forward compared to this 2017 recommendation and closer to what we would like to do,” he asserted.
 

Remission Elusive but Getting Closer

In some respects, according to Dr. Del Galdo, research and development is making relatively slow progress, especially compared with other rheumatologic diseases such as rheumatoid arthritis. “We cannot put patients with systemic sclerosis in remission yet. But I think we are one step ahead in that we’ve now established the treat-to-target approach to maximize the efficacy with which we can stall disease progression, but we cannot yet put these patients into remission,” he said. Systemic sclerosis has multiple manifestations, and fibrotic damage cannot be reversed. “Right now, the scar will remain there forever,” he noted.

Until remission is achievable, Dr. Del Galdo advises diagnosing and treating patients earlier to prevent fibrotic manifestations.

Dr. Del Galdo explained the three leading priorities on the systemic sclerosis research agenda. “There are three because it is such a complex disease. The first is considering the patient voice — this is the most important one, and the patients say they want a more holistic approach — so trialing and treating multiple manifestations together.”

Second, Dr. Del Galdo said, he would like to see a patient-reported measure developed that can capture the entire disease.

Third, from a physician’s point of view, Dr. Del Galdo said, “We want to send the patients into remission. We need to continue to further deconvolute the clinical manifestations and find the bottleneck at the beginning of the natural history of disease.

“If we can find a drug that is effective very early on, before the patients start getting the eight different manifestations with different levels of severity, then we will be on the right road, which we hope will end in remission.”

Dr. Del Galdo has served on the speakers bureau for AstraZeneca and Janssen; consulted for AstraZeneca, Boehringer Ingelheim, Capella, Chemomab, Janssen, and Mitsubishi-Tanabe; and received grant or research support from AbbVie, AstraZeneca, Boheringer Ingelheim, Capella, Chemomab, Kymab, Janssen, and Mitsubishi-Tanabe. Dr. Landewé had no relevant disclosures.

VIENNA – The use of immunosuppressive and antifibrotic drugs to treat skin and lung fibrosis leads updated recommendations from the European Alliance of Associations for Rheumatology (EULAR) for the treatment of systemic sclerosis.

“The most impactful new recommendation relates to the evidence for immunosuppressive agents and antifibrotics for the treatment of skin fibrosis and lung fibrosis,” said Francesco Del Galdo, MD, PhD, professor of experimental medicine, consultant rheumatologist, and scleroderma and connective tissue diseases specialist at Leeds Teaching Hospitals NHS Trust, Leeds, England. Dr. Del Galdo presented the update at the annual European Congress of Rheumatology.

“But there are also new recommendations, including a redefined target population for hematopoietic stem cell transplantation following cyclophosphamide, the upfront combination treatment at the time of diagnosis of pulmonary arterial hypertension [PAH], and a negative recommendation for the use of anticoagulants for pulmonary arterial hypertension,” noted Dr. Del Galdo, highlighting key updates in the 2024 recommendations.

Robert B.M. Landewé, MD, PhD, professor and rheumatologist at Amsterdam University Medical Center, Amsterdam, the Netherlands, and Zuyderland Medical Center, Heerlen, the Netherlands, co-moderated the session on EULAR recommendations. “The management of systemic sclerosis is a field in which a lot is happening,” he said. “The last update goes back to 2017, and in the meantime, many new approaches have seen the light, especially pertaining to skin fibrosis and interstitial lung disease. Six new recommendations have been coined, covering drugs like mycophenolate mofetil, nintedanib, rituximab, and tocilizumab. None of these therapies were present in the 2017 recommendations. It seems the field is now ready to further expand on targeted therapies for the management of musculoskeletal and gastrointestinal manifestations, calcinosis, and the local management of digital ulcers.”
 

‘Therapeutic Continuums’ Aid Disease Management
