The Food and Drug Administration (FDA) has issued new draft guidance that does not require additional switching studies for biosimilars seeking interchangeability. These studies were previously recommended to demonstrate that switching between the biosimilar and its reference product showed no greater risk than using the reference product alone.

“The recommendations in today’s draft guidance, when finalized, will provide clarity and transparency about the FDA’s thinking and align the review and approval process with existing and emerging science,” said Sarah Yim, MD, director of the FDA’s Office of Therapeutic Biologics and Biosimilars in a statement on June 20. “We have gained valuable experience reviewing both biosimilar and interchangeable biosimilar medications over the past 10 years. Both biosimilars and interchangeable biosimilars meet the same high standard of biosimilarity for FDA approval and both are as safe and effective as the reference product.”

An interchangeable status allows a biosimilar product to be swapped with the reference product without involvement from the prescribing provider, depending on state law.

While switching studies were not required under previous FDA guidance, the 2019 document did state that the agency “expects that applications generally will include data from a switching study or studies in one or more appropriate conditions of use.”

However, of the 13 biosimilars that received interchangeability status, 9 did not include switching study data.

“Experience has shown that, for the products approved as biosimilars to date, the risk in terms of safety or diminished efficacy is insignificant following single or multiple switches between a reference product and a biosimilar product,” the FDA stated. The agency’s investigators also conducted a systematic review of switching studies, which found no differences in risk for death, serious adverse events, and treatment discontinuations in participants switched between biosimilars and reference products and those that remained on reference products.

“Additionally, today’s analytical tools can accurately evaluate the structure and effects [of] biologic products, both in the lab (in vitro) and in living organisms (in vivo) with more precision and sensitivity than switching studies,” the agency noted.

The FDA is now calling for commentary on these draft recommendations to be submitted by Aug. 20, 2024.

Two hospitals in California in recent months have been cited by state inspectors for allowing certified registered nurse anesthetists (CRNAs) to practice beyond their scope, leading to one hospital temporarily stopping use of CRNAs in surgeries.

In one case, a CRNA changed a physician’s order from general anesthesia to spinal anesthesia for a patient who later became unresponsive and had to be transferred to another hospital, according to The Modesto Bee.

The unusual situation highlights the ongoing, often contentious debate about the proper role of CRNAs in surgery amid widely varying state scope of practice laws.

Elizabeth Bamgbose, CRNA, past president of the California Association of Nurse Anesthetists (CANA), said that the absence of CRNAs at Doctors Medical Center (DMC) in Modesto, California, had led to the cancellation of hundreds of procedures. It was an unnecessary step, she said.

“It’s unfortunate that a single surveyor has taken it upon themselves to reinterpret state regulations and redefine a practice that was efficient and safe,” said Ms. Bamgbose, a member of the CANA practice committee.

In late May, the California Department of Public Health (CDPH) issued an “immediate jeopardy” warning about DMC of Modesto. The state agency, like its counterparts in other states, acts on behalf of the Centers for Medicare and Medicaid Services (CMS) in surveying healthcare facilities. CMS defines immediate jeopardy as “a situation in which entity noncompliance has placed the health and safety of recipients in its care at risk for serious injury, serious harm, serious impairment, or death.”

The administrative warning comes with fines and requires the facility to submit an action plan to remediate the situation. The state determines through a follow-up survey whether the plan is sufficient for the facility to avoid being dropped from participation in Medicare and Medicaid.

Before the immediate jeopardy action was taken against DMC, the state had issued three previous such warnings in 2024, according to the CDPH enforcement actions dashboard.
 

CRNA Claims to Be in Charge

Stanislaus Surgical Hospital in Modesto, California, was the first facility to attract CDPH attention. It reportedly was cited in August 2023 and January 2024 surveys for a number of violations of the CMS conditions of participation, including allowing nurse anesthetists to practice beyond their scope.

According to The Modesto Bee, CDPH issued an “immediate jeopardy” order for Stanislaus in January.

The paper reported that state regulators took issue with a CRNA claiming to be the lead manager of the hospital’s anesthesia group, referring to herself as the “chief CRNA.”

Jennifer Banek, MSN, CRNA, a member of the American Association of Nurse Anesthesiology board, declined comment on the Stanislaus hospital but said that “it would not be unusual for a nurse anesthetist to serve as a leader, especially (for a) rural or underserved population.”

In April, CMS informed Stanislaus it was being terminated from Medicare, but several Congressional representatives from the Modesto area asked CMS to reconsider. The agency eventually reversed the sanction, The Modesto Bee reported.

CDPH subsequently cited DMC for CRNA scope of practice issues. A department spokesman said that CDPH teams went to DMC “to investigate practices that may not be compliant with state and federal requirements.” The agency declined to comment further until its investigations were complete.

CDPH is monitoring DMC to ensure the hospital complies with state requirements and will return for an unannounced follow-up survey “so it can provide safe, high-quality care to patients that need it,” the spokesperson said.

Although DMC would not confirm it on the record, the immediate jeopardy order led to the removal of all CRNAs, according to Ms. Banek, Ms. Bamgbose, and The Modesto Bee.

The hospital said in a statement that it is working with CDPH to address its concerns and will await a follow-up survey. “Our hospital will continue to fully participate in the Medicare and Medicaid programs during this process.”
 

Scope of Practice Confusion?

Federal and state laws and hospital bylaws all prescribe what falls within the scope of practice for a CRNA, but uncertainty remains.

Twenty-five states — including California — have legally opted out of the federal CMS requirement that a physician supervise CRNAs.

But that does not supersede state laws or hospital bylaws governing practice, said American Society of Anesthesiologists (ASA) president Ronald Harter, MD.

Five states — Alaska, Delaware, Montana, New Hampshire, and Oregon — have laws that allow nurse anesthetists to practice without physician oversight or involvement, said Dr. Harter, professor of anesthesiology at The Ohio State University Wexner Medical Center in Columbus, Ohio.

“There’s a lot of various opinions on what exactly constitutes scope of practice of a nurse anesthetist,” Dr. Harter said. “The vast majority of them work under the direction of an anesthesiologist, and in those settings, it’s typically very clear to everybody who performs what tasks within the care team,” he said.

It’s less common for nurse anesthetists to work totally independent of physician oversight, he said.

Ms. Bamgbose, however, said there is no California statute requiring physician supervision of CRNAs.

The ASA maintains that CRNAs should always be under the supervision of a physician, which can be an anesthesiologist, obstetrician, gastroenterologist, surgeon, or other physician conducting a procedure. An anesthesiologist does not necessarily have to be physically on site, but in those circumstances, the physician conducting the procedure would be, said Dr. Harter.

Nurse anesthetists are “excellent advanced practice nurses,” Dr. Harter said. “But they haven’t been to medical school; they haven’t conducted a residency in anesthesiology. [They] don’t have the medical knowledge and skills that are required to manage the medical problems that patients either bring to the OR with them or that can arise during the time that they’re under anesthesia.”
 

Filling a Gap

Nurse anesthetists see things differently.

CRNAs, by virtue of their certification, can “practice to the full extent and to the full scope, which is complete service of anesthesia,” said Ms. Bamgbose. “You can practice independently of anyone, any type of supervision,” she said.

She acknowledges that “the bylaws of any institution will govern the scope at which any healthcare professional can practice at that institution.”

Most nurse anesthetists see themselves as independent practitioners.

Seventy-five percent of CRNAs who responded to a 2023 Medscape Medical News survey said they practice independently. But even Ms. Banek said that often, the meaning of “independent” is in the eye of the beholder. “It could mean different things to various providers, especially depending on the state that they are residing in,” she said.

Ms. Banek and Ms. Bamgbose said that CRNAs can help fill a gap in anesthesiology services in underserved areas.

The Bureau of Labor Statistics estimates there are currently 32,530 anesthesiologists in the United States, with California employing the largest number, at about 5300. The Association of American Medical Colleges estimated the number at 42,263 in 2022. But the federal Health Resources and Services Administration projects a shortage of 6300 anesthesiologists over the next 15 years.

Some 61,000 CRNAs are currently practicing, with 2400 graduating each year. They are required to be board-certified and are recredentialed every 4 years. By 2025, all will be required to have a doctoral degree. Most have already achieved that status, said Ms. Banek.

“Nurse anesthetists provide care predominantly to rural and underserved areas,” she said, adding, “In many rural hospitals across the country and in all three branches of the military, CRNAs practice autonomously.”

There are 3000 CRNAs in California, said Ms. Bamgbose. Nurse anesthetists are the only anesthesiology professionals in four of 58 California counties, she said.

Ms. Banek said she had heard that some 200 cases were canceled in 1 week at DMC due to the lack of CRNAs. Having physician supervision, which she called redundant, “is really creating a barrier to care,” she said.

“We have countless state and national studies that show the safety and efficacy of our practice,” said Ms. Bamgbose. “To interrupt that care ... is incredibly disruptive to the system.”

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).

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.”

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.” 
 

Promising Research

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.” 
 

Promising Research

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.”

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.

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.

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.

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.

TOPLINE:

For patients with early multinodular hepatocellular carcinoma (HCC) who are ineligible for liver transplant, liver resection provides a survival advantage over percutaneous radiofrequency ablation and transarterial chemoembolization (TACE).

METHODOLOGY:

• The presentation of HCC is often multinodular — meaning patients have two or three nodules measuring ≤ 3 cm each. Although liver resection is considered the gold standard curative treatment for early-stage disease, experts debate its efficacy in multinodular HCC, researchers explained.
• Using two large Italian registries with data from multiple centers, researchers compared the efficacy of liver resection, percutaneous radiofrequency ablation, and TACE in 720 patients with early multinodular HCC. Overall, 296 patients underwent liver resection, 240 had percutaneous radiofrequency ablation, and 184 underwent TACE.
• To avoid crossovers between groups, the researchers considered liver resection, percutaneous radiofrequency ablation, and TACE the main treatments in each population in a hierarchical order. That meant, in the liver resection group, researchers excluded patients undergoing a superior treatment during the follow-up, such as liver transplant. In the ablation group, patients undergoing surgery to treat HCC recurrences were excluded.
• The primary outcome was overall survival at 1, 3, and 5 years. The researchers used a matching-adjusted indirect comparison (MAIC) to balance data and control for confounding factors between the three treatment groups.

TAKEAWAY:

• After MAIC adjustment, the survival rate at 1 year was slightly lower in the liver resection group — 89% vs 94% in the ablation group and 91% in the TACE group. However, at 3 and 5 years, survival rates were better in the liver resection group — 71% at 3 years and 56% at 5 years vs 65% and 40%, respectively, in the ablation group and 49% and 29%, respectively, in the TACE group.
• Median overall survival was 69 months with liver resection, 54 months with ablation, and 34 months with TACE. Multivariable Cox survival analysis confirmed a significantly higher mortality risk with ablation (hazard ratio [HR], 1.41; P = .01) and TACE (HR, 1.86; P = .001) than with liver resection.
• In competing risk analyses, patients who underwent liver resection had a lower risk for HCC-related death than peers who had ablation (HR, 1.38; P = .07) or TACE (HR, 1.91; P = .006).
• In a subgroup survival analysis of patients with Child-Pugh class B cirrhosis, liver resection provided significantly better overall survival than TACE (HR, 2.79; P = .001) and higher overall survival than ablation (HR, 1.44; P = .21), but these findings were not statistically significant.

IN PRACTICE:

“The main result of the current study is the indisputable superiority” of liver resection over percutaneous radiofrequency ablation and TACE in patients with multinodular HCC, the researchers concluded. “For patients with early multinodular HCC who are ineligible for transplant, LR [liver resection] should be prioritized as the primary therapeutic option,” followed by percutaneous radiofrequency ablation and TACE, when resection is not feasible.

The authors of an invited commentary said the analysis provides “convincing” data that liver resection leads to superior 3- and 5-year survival. “All of our local therapies are getting better. Making each available under different clinical circumstances and combining these when appropriate provides patients with the best chance at cure with the least invasiveness,” the editorialists added.
 

SOURCE:

The study, with first author Alessandro Vitale, MD, PhD, with the Department of Surgical, Oncological and Gastroenterological Sciences, University of Padova, Padua, Italy, and the accompanying commentary were published online last month in JAMA Surgery.

LIMITATIONS:

Selection bias cannot be ruled out due to potential hidden variables that were not collected in the centers’ databases. Not all patients included in the study were potentially treatable with all three proposed approaches. The study population was derived from Italian centers, which may have limited the generalizability of the results.

DISCLOSURES:

The study reported no specific funding. The authors reported various disclosures during the conduct of the study, including ties to AstraZeneca, AbbVie, Bayer, MSD, Roche, and Eisai. An editorialist reported ties to Medtronic, Theromics, Vergent Bioscience, Imugene, Sovato Health, XDemics, and Imugene.

Several new studies in lung cancer have opened their doors recently. Is one of your patients eligible to participate?

Resected stage II, IIIA, or IIIB with nodal involvement non–small cell lung cancer (NSCLC). Adult patients with this type of cancer can join a randomized, controlled, phase 3 study assessing whether an investigational drug called V940 added to pembrolizumab (Keytruda) delays cancer recurrence better than pembrolizumab alone.

V940 is an individualized neoantigen therapy designed to generate T-cell antitumor responses targeted to a patient’s specific mutation profile.

V940 plus pembrolizumab showed a trend toward longer recurrence-free survival vs pembrolizumab alone in a recent phase 2 study in melanoma (hazard ratio, 0.561; P = .053).

In the current trial, one group of participants will receive intramuscular injections of V940 every 3 weeks plus intravenous (IV) pembrolizumab every 6 weeks for up to approximately 1 year or until disease recurrence or unacceptable toxicity, whichever happens first. The other people in the trial will be on the same schedule, with a placebo replacing V940.

Centers in Florida, Georgia, Kentucky, Montana, New Jersey, New York, North Dakota, and six other countries started recruiting for the trial’s 868 participants in December 2023. Disease-free survival is the primary endpoint. Overall survival over approximately 12 years and quality of life (QoL) are secondary endpoints. More details at clinicaltrials.gov.

Metastatic NSCLC with a programmed cell death ligand 1 (PD-L1)–tumor proportion score of > 50%. Adults in this clinical situation are eligible for a randomized, open-label, phase 3 trial to determine whether an experimental antibody-drug conjugate called MK-2870 added to standard pembrolizumab prolongs survival.

MK-2870 delivers a cytotoxin to cancer cells by binding to trophoblast cell-surface antigen 2, known to promote tumor cell growth and metastasis. For up to 2 years, half of participants will receive MK-2870 by IV every 2 weeks plus IV pembrolizumab every 6 weeks. The other group will receive only pembrolizumab.

In December 2023, study sites in Georgia, Minnesota, Mississippi, Nevada, Oregon, Australia, Denmark, Taiwan, and Turkey started seeking the trial’s 614 participants. Overall survival over approximately 4 years is the primary endpoint; QoL is a secondary endpoint. More details at clinicaltrials.gov.

Untreated locally advanced or metastatic NSCLC with KRAS G12C mutations. Individuals with this type of lung cancer may be interested in a randomized, controlled, phase 3 study examining whether an experimental oral KRAS G12C inhibitor called LY3537982 boosts the effectiveness of standard treatment and patients can tolerate the combination. Currently approved KRAS G12C inhibitors sotorasib (Lumakras, Lumykras) and adagrasib (Krazati) are indicated for second-line treatment; this trial may lead to a first-line approval for newcomer LY3537982.

The trial has three parts: dose optimization, safety, and efficacy. During dose optimization, each participant will take one of two oral doses of LY3537982 and receive IV pembrolizumab every 3 weeks. In the safety phase, all participants will receive oral LY3537982 at the chosen dose plus standard therapy of 3-times-weekly IV pembrolizumab, pemetrexed, and a platinum therapy (cisplatin or carboplatin). In the experimental phase, for up to about 1 year, participants will receive one of these four options: Pembrolizumab plus LY3537982, pembrolizumab plus a placebo, standard therapy plus LY3537982, or standard therapy plus a placebo.

The study, which is planning to recruit 1016 participants, opened across 16 US states and 12 countries worldwide in December 2023. Sites in 11 more US states, the District of Columbia, Brazil, Canada, China, India, and 11 more European countries are gearing up. Adverse events and progression-free survival are the primary endpoints. Overall survival over approximately 3 years and QoL are secondary endpoints. More details at clinicaltrials.gov.

Unresectable, untreated locally advanced or metastatic non-squamous NSCLC with human epidermal growth factor receptor 2 (HER2) mutations. People with this diagnosis who have HER2 mutations instead of KRAS G12C mutations can participate in a phase 3 study comparing an investigational oral first-line treatment with standard IV therapy. The drug in this study, zongertinib, is a HER2 tyrosine kinase inhibitor.

For up to approximately 4 years, one group of participants will take oral zongertinib only, and the other individuals will receive IV pembrolizumab, pemetrexed, and a platinum agent (cisplatin or carboplatin). Study sites in California, Missouri, South Carolina, Australia, China, Japan, South Korea, and Singapore opened in January ready to welcome 270 participants. Progression-free survival is the primary outcome. Overall survival over 53 months and QoL are secondary endpoints. More details at clinicaltrials.gov.

Completely resected stage IIB, IIIA, or select IIIB, PD-L1–positive NSCLC. Adults with this type of lung cancer who have received adjuvant platinum-based chemotherapy may be eligible for a randomized, controlled, phase 3 study to assess whether two immune checkpoint inhibitors are better than one at delaying cancer recurrence. In this trial, tiragolumab will be added to the approved PD-L1 inhibitor atezolizumab (Tecentriq).

A recent study, however, found that tiragolumab did not confer an additional benefit when added to atezolizumab, carboplatin, and etoposide in untreated extensive-stage small cell lung cancer.

In the current trial, one group of participants will receive IV atezolizumab and tiragolumab, while the other people will receive a placebo instead of tiragolumab. Centers in California, Georgia, Illinois, New Mexico, Australia, China, South Korea, and Taiwan started recruiting for the trial’s 1150 participants in March 2024. Disease-free survival is the primary endpoint. Overall survival over approximately 15 years and QoL are secondary outcomes. More details at clinicaltrials.gov.

Previously treated metastatic or non-operable non-squamous NSCLC. Adults in this position who have received no more than one platinum-based chemotherapy and one anti–PD-L1 drug are sought for a randomized, open-label, phase 3 trial comparing second-line standard docetaxel with experimental antibody-drug conjugate sigvotatug vedotin. Patients who have tumors with certain treatable genomic alterations must have received at least one drug targeted to that alteration, as well as a platinum-based agent.

Approximately half the participants will receive sigvotatug vedotin by IV every 2 weeks, and the other half will receive IV docetaxel every 3 weeks. The study opened in March across 13 US states, France, Hungary, Poland, and Spain seeking 600 people eligible to participate. The primary outcomes are overall survival over approximately 5 years and objective response rate. QoL is a secondary outcome. More details at clinicaltrials.gov.All trial information is from the National Institutes of Health US National Library of Medicine (online at clinicaltrials.gov).

Several new studies in lung cancer have opened their doors recently. Is one of your patients eligible to participate?

Resected stage II, IIIA, or IIIB with nodal involvement non–small cell lung cancer (NSCLC). Adult patients with this type of cancer can join a randomized, controlled, phase 3 study assessing whether an investigational drug called V940 added to pembrolizumab (Keytruda) delays cancer recurrence better than pembrolizumab alone.

V940 is an individualized neoantigen therapy designed to generate T-cell antitumor responses targeted to a patient’s specific mutation profile.

V940 plus pembrolizumab showed a trend toward longer recurrence-free survival vs pembrolizumab alone in a recent phase 2 study in melanoma (hazard ratio, 0.561; P = .053).

In the current trial, one group of participants will receive intramuscular injections of V940 every 3 weeks plus intravenous (IV) pembrolizumab every 6 weeks for up to approximately 1 year or until disease recurrence or unacceptable toxicity, whichever happens first. The other people in the trial will be on the same schedule, with a placebo replacing V940.

Centers in Florida, Georgia, Kentucky, Montana, New Jersey, New York, North Dakota, and six other countries started recruiting for the trial’s 868 participants in December 2023. Disease-free survival is the primary endpoint. Overall survival over approximately 12 years and quality of life (QoL) are secondary endpoints. More details at clinicaltrials.gov.

Metastatic NSCLC with a programmed cell death ligand 1 (PD-L1)–tumor proportion score of > 50%. Adults in this clinical situation are eligible for a randomized, open-label, phase 3 trial to determine whether an experimental antibody-drug conjugate called MK-2870 added to standard pembrolizumab prolongs survival.

MK-2870 delivers a cytotoxin to cancer cells by binding to trophoblast cell-surface antigen 2, known to promote tumor cell growth and metastasis. For up to 2 years, half of participants will receive MK-2870 by IV every 2 weeks plus IV pembrolizumab every 6 weeks. The other group will receive only pembrolizumab.

In December 2023, study sites in Georgia, Minnesota, Mississippi, Nevada, Oregon, Australia, Denmark, Taiwan, and Turkey started seeking the trial’s 614 participants. Overall survival over approximately 4 years is the primary endpoint; QoL is a secondary endpoint. More details at clinicaltrials.gov.

Untreated locally advanced or metastatic NSCLC with KRAS G12C mutations. Individuals with this type of lung cancer may be interested in a randomized, controlled, phase 3 study examining whether an experimental oral KRAS G12C inhibitor called LY3537982 boosts the effectiveness of standard treatment and patients can tolerate the combination. Currently approved KRAS G12C inhibitors sotorasib (Lumakras, Lumykras) and adagrasib (Krazati) are indicated for second-line treatment; this trial may lead to a first-line approval for newcomer LY3537982.

The trial has three parts: dose optimization, safety, and efficacy. During dose optimization, each participant will take one of two oral doses of LY3537982 and receive IV pembrolizumab every 3 weeks. In the safety phase, all participants will receive oral LY3537982 at the chosen dose plus standard therapy of 3-times-weekly IV pembrolizumab, pemetrexed, and a platinum therapy (cisplatin or carboplatin). In the experimental phase, for up to about 1 year, participants will receive one of these four options: Pembrolizumab plus LY3537982, pembrolizumab plus a placebo, standard therapy plus LY3537982, or standard therapy plus a placebo.

The Centers for Medicare & Medicaid Services (CMS) has announced the conclusion of a program that provided billions in early Medicare payments to those affected by the Change Healthcare/UnitedHealth Group cyberattack last winter. The Accelerated and Advance Payment program, which began in early March to assist hospitals and practices facing significant reimbursement delays, will stop accepting applications after July 12, 2024.

CMS reported that the program advanced more than $2.55 billion in Medicare payments to > 4200 Part A providers, including hospitals, and more than $717.18 million in payments to Part B suppliers such as physicians, nonphysician practitioners, and durable medical equipment suppliers.

According to CMS, the Medicare billing system is now functioning properly, and 96% of the early payments have been recovered. The advances were to represent ≤ 30 days of typical claims payments in a 3-month period of 2023, with full repayment expected within 90 days through “automatic recoupment from Medicare claims” — no extensions allowed.

The agency took a victory lap regarding its response. “In the face of one of the most widespread cyberattacks on the US health care industry, CMS promptly took action to get providers and suppliers access to the funds they needed to continue providing patients with vital care,” CMS Administrator Chiquita Brooks-LaSure said in a statement. “Our efforts helped minimize the disruptive fallout from this incident, and we will remain vigilant to be ready to address future events.”

Ongoing Concerns from Health Care Organizations

Ben Teicher, an American Hospital Association spokesman, said that the organization hopes that CMS will be responsive if there’s more need for action after the advance payment program expires. The organization represents about 5000 hospitals, health care systems, and other providers.

“Our members report that the aftereffects of this event will likely be felt throughout the remainder of the year,” he said. According to Teicher, hospitals remain concerned about their ability to process claims and appeal denials, the safety of reconnecting to cyber services, and access to information needed to bill patients and reconcile payments.

In addition, hospitals are concerned about “financial support to mitigate the considerable costs incurred as a result of the cyberattack,” he said.

Charlene MacDonald, executive vice-president of public affairs at the Federation of American Hospitals, which represents more than 1000 for-profit hospitals, sent a statement to this news organization that said some providers “are still feeling the effects of care denials and delays caused by insurer inaction.

“We appreciate that the Administration acted within its authority to support providers during this unprecedented crisis and blunt these devastating impacts, especially because a vast majority of managed care companies failed to step up to the plate,” she said. “It is now time to shift our focus to holding plans accountable for using tactics to delay and deny needed patient care.”

Cyberattack Impact and Response

The ransom-based cyberattack against Change Healthcare/UnitedHealth Group targeted an electronic data interchange clearing house processing payer reimbursement systems, disrupting cash flows at hospitals and medical practices, and affecting patient access to prescriptions and life-saving therapy.

Change Healthcare — part of the UnitedHealth Group subsidiary Optum — processes half of all medical claims, according to a Department of Justice lawsuit. The American Hospital Association described the cyberattack as “the most significant and consequential incident of its kind” in US history.

By late March, UnitedHealth Group said nearly all medical and pharmacy claims were processing properly, while a deputy secretary of the US Department of Health & Human Services told clinicians that officials were focusing on the last group of clinicians who were facing cash-flow problems.

Still, a senior advisor with CMS told providers at that time that “we have heard from so many providers over the last several weeks who are really struggling to make ends meet right now or who are worried that they will not be able to make payroll in the weeks to come.”
