Dana-Farber Moves to Retract, Correct Dozens of Cancer Papers Amid Allegations
News of the investigation follows a blog post by British molecular biologist Sholto David, MD, who flagged almost 60 papers published between 1997 and 2017 that contained image manipulation and other errors. Some of the papers were published by Dana-Farber’s chief executive officer, Laurie Glimcher, MD, and chief operating officer, William Hahn, MD, on topics including multiple myeloma and immune cells.
Mr. David, who blogs about research integrity, highlighted numerous errors and irregularities, including copying and pasting images across multiple experiments to represent different days within the same experiment, sometimes rotating or stretching images.
In one case, Mr. David equated the manipulation with tactics used by “hapless Chinese papermills” and concluded that “a swathe of research coming out of [Dana-Farber] authored by the most senior researchers and managers appears to be hopelessly corrupt with errors that are obvious from just a cursory reading the papers.”
“Imagine what mistakes might be found in the raw data if anyone was allowed to look!” he wrote.
Barrett Rollins, MD, PhD, Dana-Farber Cancer Institute’s research integrity officer, declined to comment on whether the errors represent scientific misconduct, according to STAT. Rollins told ScienceInsider that the “presence of image discrepancies in a paper is not evidence of an author’s intent to deceive.”
Access to new artificial intelligence tools is making it easier for data sleuths, like Mr. David, to unearth data manipulation and errors.
The current investigation closely follows two other investigations into the published work of Harvard University’s former president, Claudine Gay, and Stanford University’s former president, Marc Tessier-Lavigne, which led both to resign their posts.

Young Myeloma Specialist Forges Ahead, Gives Back
Ahead of the conference held in San Diego in December, Dr. Mohyuddin, a blood cancer specialist with a focus on multiple myeloma and medical education, put out a heartfelt appeal on X (formerly Twitter): “If you’re a trainee and interested in meeting me at #ASH23, please reach out … (especially if [international medical graduate]) I’d love to meet and offer support in whatever capacity I can! I can’t have a research project for each one of you, but happy to help/mentor in any other way possible,” he posted on X back in late November.
An international medical graduate himself, Dr. Mohyuddin recalls how overwhelmed he felt when he first attended an annual ASH conference as a trainee, so he aims to reassure others that they “don’t have to know everything.”
“It’s about networking and broadening horizons,” he said in an interview that took place between ASH sessions, his own research presentations, and meetings with the many trainees who took him up on the offer he made via X. “I’ve spent most of this ASH meeting trainees — it’s the most rewarding thing for me at these meetings.
“Reassurance is a lot of what we do in oncology,” he continued, drawing a connection between his affinity for helping trainees and providing compassionate care to patients. “For an oncologist, the single most important thing is having excellent communication skills and being able to express support and empathy. The ability to connect deeply with your patients during their time of need is profoundly important.
“You can compensate for lack of knowledge, because we have so many other sources of support for knowledge, but you simply cannot compensate for poor communication skills, and your patient suffers as a result,” he said.
Relationship Building
In addition to the guidance he received from mentors, Dr. Mohyuddin noted that it was the chance to build supportive, empathetic relationships that drew him to specialize in blood cancer and, in particular, to caring for patients with multiple myeloma and conducting research focused on improving the patient experience.
Dr. Mohyuddin attended medical school at the Aga Khan University in Pakistan, then completed his internal medicine residency and fellowship at the University of Kansas in Kansas City. As a chief resident there, he focused on novel approaches to education delivery and improving access to research for trainees. As a fellow, he developed clinical and research interests in multiple myeloma, which he describes as an “incredibly rewarding field” marked by “truly spectacular advances over the last two decades.”
“There are some cancers you can cure, which means you don’t get to see patients often, and there are some you can’t cure, where patients die early, and there’s not a lot of time to build a relationship,” he said. “But there are some where patients can do well even though they aren’t currently cured, and you get to form really amazing and meaningful relationships over a long period of time.
“Multiple myeloma occupies that space, and that’s why I’m drawn to it,” Dr. Mohyuddin added, noting that he doesn’t shy away from forging emotional connections with patients. “I recognize that makes me vulnerable, but I think that is essentially what your patients deserve from you — to be invested at an emotional level with them through their suffering.”
Improving value and the patient experience
“One thing, philosophically, that I research is value in multiple myeloma care: identifying areas where we are overtreating patients and where we can do less and get away with it,” he said.
Despite the major advances in multiple myeloma in recent years, which “represent a lot of what is going right with oncology,” this blood cancer still “also represents a lot of what is wrong with oncology,” he noted. As an example, he cited “the approval of low-value drugs, the sequencing of drugs, adding more and more drugs without responsibly addressing quality-of-life questions, and identifying more responsible ways to provide high-value efficacious care without bankrupting the economy.
“So my research and policy work apply to that,” he explained. “What can we do better? What sort of trials should we be doing? What populations do we enroll? Are we asking the right questions or looking at trivialities? Are we serving patients foremost?”
Sometimes, this means comparing multiple myeloma staging systems in a real-world cohort, or assessing whether a widely available, cheap, and safe drug like budesonide can help patients avoid diarrhea during chemotherapy, whether control arms in myeloma randomized trials are fair, whether drugs ever get approved in low- or middle-income countries after their approval in the United States, and whether smoldering myeloma, a multiple myeloma precursor, really requires treatment, as current guidelines suggest, or if patients would do just as well — or perhaps better — with a close surveillance protocol.
“Pharma won’t do those studies and many key opinion leaders feel the question [about whether smoldering myeloma needs to be treated] has already been answered, so we are launching a prospective study that will define the natural history of smoldering myeloma and allow for patients to stay off therapy while undergoing rigorous surveillance with imaging,” he said.
Another study Dr. Mohyuddin hopes to launch soon will look at a “start low, go slow” treatment approach for the frailest patients with newly diagnosed myeloma.
His upbringing in Pakistan, where there are “mind-boggling” differences in health care access, affordability, and outcomes when compared with the United States, provided a foundation for both his “enthusiasm for cost-effective care” and his desire to give back, he said.
Another aspect of life in Pakistan — an across-the-board sense of closeness and solidarity in families and communities that is sometimes lacking in the United States — contributed to his desire to build relationships.
“That is something I dearly miss,” he said. “I am very privileged and so thankful to be here in the US, but that is one thing I do deeply miss.”
Connecting and Making a Difference
Dr. Mohyuddin seeks connection through his relationships with patients, trainees, and his many followers on social media platforms like X, where he frequently shares his thoughts on research quality and findings, heme/onc trends, and treatment-related insight.
“How to treat myeloma after #ASH23,” he posted on X as the conference came to a close. His takeaways: Don’t treat smoldering myeloma, do quadruple therapy for transplant-eligible patients (but no cd38 maintenance therapy afterward), don’t do quads for carfilzomib in newly diagnosed frail or older patients, and don’t do a salvage autologous transplant, no matter how good the first transplant was.
Dr. Mohyuddin also works to make a difference through his research and involvement in helping to launch initiatives like Common Sense Oncology, an ambitious global effort to reform cancer clinical trials and care, and through a current project with colleagues in India and Pakistan to create a consortium for pooling data on hematologic malignancies from South Asian countries. The hope is that such a collaborative effort will lead to good prospective research relevant to the needs of participating countries, he explained.
“Those are things where I want to make a difference. Taking care of patients is number one, but more than research, the number two thing for me is teaching and hopefully inspiring trainees and others to think differently, to look at data differently,” he said, noting that despite the major advances in myeloma, the reality is that “a lot of what we offer in oncology is very marginal.”
The effect sizes of interventions are often very small, and outcomes can still be really bad, he explained, adding that “[i]t really hits you when you see a lot of death and suffering. It’s a huge wake-up call … we have so many advances, but the reality is very, very sobering.
“Critically understanding and interpreting data is something where education really fails us. I’m incredibly passionate about it. I’ve found great resources to help me interpret data better, and I want to make them more accessible and inspire others to understand better,” he said. “We need to know how to defend ourselves from the hype.”
His efforts have not gone unnoticed. Dr. Mohyuddin was the recipient of the 2023 Hematology and Medical Oncology Fellowship Faculty Teaching Award at the University of Utah, Salt Lake City, where he is currently a faculty member.
“The recognition means more than any publication or grant award,” he said. “It’s great to know that medical education is appreciated, because so often we are in a rat race of getting more papers and grants out, but teaching and inspiring people is what is really, really important to me.”

CRISPR-Based Gene Therapy Earns Beta Thalassemia Approval
The approval, which comes more than 2 months ahead of a target action date of March 30, marks the second for the landmark therapy. The FDA greenlit the CRISPR gene therapy to treat sickle cell disease last December.
The autologous, ex vivo, CRISPR/Cas9 gene-edited therapy from Vertex and CRISPR Therapeutics is the first to use the gene-editing tool CRISPR.
The transfusion-dependent beta thalassemia approval is based on data from pivotal studies showing “consistent and durable response to treatment” in 52 patients who received an infusion and followed for up to 4 years. Treatment conferred transfusion independence in patients with transfusion-dependent beta thalassemia, according to a press release from Vertex late last year.
Vertex noted in a new press statement that expanded approval means about 1000 patients aged 12 years or older will be eligible for the one-time treatment for this indication.
Exa-cel requires administration at authorized treatment centers experienced in stem cell transplantation.
The therapy, which has a list price of $2.2 million in the United States, should be available initially at nine authorized treatment centers early this year, with more to come, according to Vertex.

Serum Hormone Concentrations May Predict Aromatase Inhibitor Benefit for BC Prevention
, according to findings from a case-control study using data from a large breast cancer prevention trial.
In the randomized, placebo-controlled IBIS-II prevention trial of 3864 women aged 40-70 years at increased risk for developing breast cancer, treatment with the aromatase inhibitor anastrozole was associated with a 49% reduction in breast cancer incidence. At median follow-up of 131 months, breast cancer occurred in 85 (4.4%) versus 165 (8.5%) of patients in the anastrozole and placebo arms, respectively.
A preplanned case-control study involving 212 participants from the anastrozole group (72 cases and 140 controls) and 416 from the placebo group (142 cases and 274 controls), showed a significant trend toward increasing breast cancer risk with increasing estradiol-to-sex hormone binding globulin (SHBG) ratio in the placebo group, but not in the anastrozole group (trend per quartile, 1.25 vs 1.06), reported Jack Cuzick, PhD, of the Wolfson Institute of Population Health, Queen Mary University of London, UK, and colleagues.
A weaker but still significant effect was observed for the testosterone-SHBG ratio in the placebo group (trend, 1.21), but again, no such effect was seen in the anastrozole group (trend, 1.18).
A relative benefit was seen for anastrozole in estradiol concentration quartiles 2, 3, and 4 (relative risk [RR], 0.55, 0.54, and 0.56, respectively), but not in quartile 1.
The findings were published online December 6 in The Lancet Oncology.
Study participants were recruited from 153 breast cancer treatment centers across 18 countries and randomized in a 1:1 ratio to receive 1 mg of oral anastrozole daily or placebo. For the case-control analysis, the investigators looked at the effects of baseline estradiol to SHBG ratio on the development of all breast cancers, including ductal carcinoma in situ. They also assessed the relative benefit of anastrozole versus placebo.
Case patients were those diagnosed with breast cancer after trial entry through data cutoff on October 22, 2019, and who had not used hormone replacement therapy within 3 months of trial entry or during the trial. Controls were participants without breast cancer who were randomly selected and matched according to treatment group, age, and follow-up time.
“Although the association between estradiol and breast cancer risk is well established, less is known about whether the concentrations of these hormones have an effect on the efficacy of preventive therapy with selective estrogen receptor modulators or aromatase inhibitors in women at increased risk of developing breast cancer,” the investigators noted, explaining that in the current analysis, they “tested the hypothesis that, for women with a low estradiol–SHBG ratio, anastrozole would provide little or no reduction in the risk of breast cancer.”
The results from the placebo group “confirm the increasing risk of breast cancer associated with higher estradiol and testosterone concentrations, and a decreasing risk associated with increasing SHBG concentrations in women who were not randomly allocated to receive anastrozole,” they said.
“However, to our knowledge, this is the first report of the effect of low concentrations of estradiol or testosterone on a lack of response to aromatase inhibitor treatment, either as a preventive measure or in the adjuvant setting,” they added. “These data provide support for the hypothesis that preventive therapy with an aromatase inhibitor is likely to be most effective for women with higher estradiol-to-SHBG ratios and, conversely, of little or no benefit for those with low estradiol-to-SHBG ratios.”
Thus, measurement of estradiol and SHBG concentrations might be helpful in making decisions about using inhibitors both for treatment and prevention, they continued, underscoring the importance of using assays sensitive enough to measure low estradiol concentrations in the plasma in postmenopausal women.
“We used a very sensitive liquid chromatography–tandem mass spectroscopy assay (lower limit of sensitivity of 3 pmol/L), which allowed us to accurately measure the low concentrations of estradiol and SHBG in the serum samples from our population of postmenopausal women. Wider use of this type of assay or a similar assay will be necessary to implement any of the actions suggested by this study,” they explained.
The findings “suggest a potential role for measuring estradiol, testosterone, and SHBG more widely, both in determining which individuals are at high risk and the likely response to endocrine treatment,” they concluded, noting that measuring serum hormones is inexpensive and, if used more routinely in high-risk clinics and for treatment of early breast cancer, could “substantially improve disease management.”

, according to findings from a case-control study using data from a large breast cancer prevention trial.
In the randomized, placebo-controlled IBIS-II prevention trial of 3864 women aged 40-70 years at increased risk for developing breast cancer, treatment with the aromatase inhibitor anastrozole was associated with a 49% reduction in breast cancer incidence. At median follow-up of 131 months, breast cancer occurred in 85 (4.4%) versus 165 (8.5%) of patients in the anastrozole and placebo arms, respectively.
A preplanned case-control study involving 212 participants from the anastrozole group (72 cases and 140 controls) and 416 from the placebo group (142 cases and 274 controls), showed a significant trend toward increasing breast cancer risk with increasing estradiol-to-sex hormone binding globulin (SHBG) ratio in the placebo group, but not in the anastrozole group (trend per quartile, 1.25 vs 1.06), reported Jack Cuzick, PhD, of the Wolfson Institute of Population Health, Queen Mary University of London, UK, and colleagues.
A weaker but still significant effect was observed for the testosterone-SHBG ratio in the placebo group (trend, 1.21), but again, no such effect was seen in the anastrozole group (trend, 1.18).
A relative benefit was seen for anastrozole in estradiol concentration quartiles 2, 3, and 4 (relative risk [RR], 0.55, 0.54, and 0.56, respectively), but not in quartile 1.
The findings were published online December 6 in The Lancet Oncology.
Study participants were recruited from 153 breast cancer treatment centers across 18 countries and randomized in a 1:1 ratio to receive 1 mg of oral anastrozole daily or placebo. For the case-control analysis, the investigators looked at the effects of baseline estradiol to SHBG ratio on the development of all breast cancers, including ductal carcinoma in situ. They also assessed the relative benefit of anastrozole versus placebo.
Case patients were those diagnosed with breast cancer after trial entry through data cutoff on October 22, 2019, and who had not used hormone replacement therapy within 3 months of trial entry or during the trial.

New Multiple Myeloma Staging Systems Outperform the Standard
.
The findings should encourage greater use of these newer staging systems in routine clinical practice, first author Manni Mohyuddin, MD, said during a presentation at the American Society of Hematology annual meeting.
Dr. Mohyuddin and his colleagues retrospectively compared the standard Revised International Staging System (R-ISS) with two newer systems, the Second Revision of the R-ISS (R2-ISS) and the Mayo Additive Staging System (MASS), using real-world data from nearly 500 patients with newly diagnosed multiple myeloma.
The R-ISS, the most common multiple myeloma staging system, incorporates a range of prognostic features, including high-risk genetic markers assessed using fluorescence in situ hybridization as well as levels of lactate dehydrogenase, albumin, and beta-2 microglobulin, explained Dr. Mohyuddin, assistant professor at the Huntsman Cancer Institute, University of Utah, Salt Lake City.
R2-ISS and MASS include additional factors that reflect experts’ growing understanding of multiple myeloma. Specifically, the systems also evaluate a gain of chromosome 1q, in which patients have an extra copy of chromosome 1q, as well as the additive effects of multiple high-risk cytogenetic abnormalities, both of which indicate worse prognosis in multiple myeloma, Dr. Mohyuddin said in an interview.
To compare the three staging systems, the investigators used information on newly diagnosed patients in the Flatiron Health EHR–derived deidentified database, which includes data from cancer clinics across the United States. Patients were followed from first-line treatment initiation until death, the end of the study period, or last recorded activity.
The patients from the database had a median age of 70 years, and most had not received a transplant. The most common cytogenetic abnormality was gain 1q, present in about one third of patients.
Given that the R2-ISS originated from patients in clinical trials, Dr. Mohyuddin noted the importance of assessing how the system would perform in a real-world setting.
Of the 497 patients in the analysis, the R-ISS staging system classified 24% as stage I, 63% as stage II, and 13% as stage III. Overall survival differed across these R-ISS stages, indicating the system was prognostic for survival. Median overall survival was not reached for those with stage I disease, was 62.9 months for those with stage II disease, and 37.6 months for those with stage III disease.
Because the R-ISS doesn’t consider the additive effect of multiple cytogenetic abnormalities, many patients end up in the R-ISS stage II category but ultimately may have vastly different outcomes, Dr. Mohyuddin said.
The R2-ISS includes four risk categories, which provide more granularity to the stage II classification: Stage I is low risk, stage II is low-intermediate, stage III is intermediate, and stage IV is high risk. Using this staging system, 20% of patients were stage I, 25% were stage II, 46% were stage III, and 9% were stage IV.
The R2-ISS was also prognostic for survival, which generally worsened from stage I to stage IV: Median overall survival was not reached in stage I patients, was 69.3 months for stage II, 50.0 months for stage III, and 50.6 months for stage IV patients. However, Dr. Mohyuddin noted that there was some overlap in the survival curves for stages I and II and for stages III and IV.
When applying MASS, 34% of patients were categorized as stage I, 35% as stage II, and 31% as stage III disease. This system was prognostic for survival as well, with median overall survival of 76.9 months for stage I, 61.2 months for stage II, and 45.0 months for stage III.
With R2-ISS, many of those in R-ISS stage II are moved into stage I and III. With MASS, the R-ISS stage II patients are more evenly distributed across stages I, II, and III.
In other words, “we show that both these newer staging systems basically recategorize patients into different stages,” essentially “decreasing the number of people in the large, ambiguous (R-ISS) stage II category,” said Dr. Mohyuddin.
Dr. Mohyuddin and colleagues also evaluated the staging systems in fully adjusted analyses that controlled for age, race/ethnicity, sex, practice type, and diagnosis year.
Using R2-ISS, stage I patients had a similar risk for death compared with stage II patients (hazard ratio [HR], 1.2). Compared with stage I patients, stage III and IV patients had comparable risks for death, both about 2.5-fold higher than in those with stage I disease (HR, 2.4 and 2.6, respectively).
Compared with stage I MASS patients, those with stage II had a twofold higher risk for death (HR, 2.0), and those with stage III had an almost threefold higher risk (HR, 2.7).
Although no system considers all factors associated with myeloma outcomes, R2-ISS and MASS do offer a benefit over R-ISS, Dr. Mohyuddin said.
He added that the R2-ISS and MASS are similar from a statistical standpoint, but he gave MASS a slight edge for use in clinical practice.
MASS “more cleanly demarcated [patients] into prognostic subsets,” plus it is “a little easier to remember by heart,” he explained. MASS also puts more emphasis on the presence of multiple high-risk cytogenetic abnormalities, which is a worse prognostic in this era of quadruplet therapy for multiple myeloma, he added.
Because the study largely took place in an era when triplet therapy dominated, “we would be curious to see, with longer follow-up and more use of quadruplets, how these staging systems would perform,” he said.
Despite the benefits of these newer staging systems, many factors play a role in multiple myeloma outcomes, Dr. Mohyuddin explained. Staging systems are “only a piece of the puzzle.”
Dr. Mohyuddin reported having no financial interests to disclose.

FROM ASH 2023
No Benefit to Salvage Transplant in R/R Multiple Myeloma
Patients receiving a second, salvage-autologous stem cell transplant alongside lenalidomide-dexamethasone maintenance therapy did not demonstrate improved progression-free survival (PFS) or overall survival compared with patients who continued the two-drug regimen without salvage transplant, according to research presented at the American Society of Hematology annual meeting.
The primary phase 3 analysis, published in 2021, showed no survival benefit following salvage transplant at the time of relapse, though it only followed patients for a median of 37 months.
However, because a significant fraction of patients in the transplant arm — about 29% — did not undergo the planned salvage transplant before dropping out of the study, the researchers performed further analyses that “suggested a survival benefit in patients who actually received the transplant,” first author Marc-Andrea Baertsch, MD, of the German Cancer Research Center and University Hospital Heidelberg, reported at ASH.
Now, the latest analysis, which followed patients for a median of 99 months (8.25 years), confirmed the initial 2021 findings, Dr. Baertsch explained.
“The writing on the wall is clear: Don’t repeat a transplant at the time of relapse for those who have already gotten a transplant,” said Manni Mohyuddin, MD, of the University of Utah in Salt Lake City, who was not involved in the research. Dr. Mohyuddin added, however, that this finding doesn’t apply to those who haven’t yet gotten a transplant. “Data from other trials suggests a role of transplant in this situation, depending on the unique circumstances.”
The current trial included 282 adult patients, aged 75 years or younger, with relapsed or refractory multiple myeloma. Between 2010 and 2016, patients in the intention-to-treat analysis (n = 277) were randomized to lenalidomide-dexamethasone reinduction and maintenance, along with salvage high-dose chemotherapy with melphalan and autologous stem cell transplantation (n = 139) or just continuous lenalidomide-dexamethasone until progression (n = 138).
Patients in both arms received three cycles of lenalidomide-dexamethasone up front: 25 mg of lenalidomide on days 1 through 21, and 40 mg of dexamethasone on days 1, 8, 15, and 22 in 4-week cycles. Those in the salvage transplant arm then received high-dose chemotherapy with 200 mg/m2 of melphalan followed by transplant and 10 mg of lenalidomide maintenance therapy daily, while those in the control arm continued with receiving lenalidomide-dexamethasone.
All patients had received one to three prior lines of therapy, had good performance status, and had a time-to-disease-progression of at least 12 months after frontline autologous stem cell transplant.
In the primary 2021 study, patients in the salvage transplant group did not demonstrate a survival benefit (hazard ratio [HR] for PFS, 0.87; HR for overall survival, 0.81).
In the latest analysis, no survival benefit emerged after following patients for a median of about 8 years. Patients in the salvage transplant arm had a median PFS of 20.5 months vs 19.3 months in the continuous therapy arms (HR, 0.98; 95% CI, 0.76-1.27; P = .9). Median overall survival was 67.1 months in the salvage transplant arm and 62.7 months in the continuous treatment arm (HR, 0.89; 95% CI, 0.66 - 1.20; P = .44).
Time to first progression after frontline transplant was associated with a PFS benefit but did not predict an overall survival benefit, Dr. Baertsch noted.
When evaluating outcomes from the time of salvage transplant to account for the high number of dropouts, the PFS and overall survival findings held. Patients who received salvage transplant did not experience significantly improved PFS (HR, 0.91) or overall survival (76.3 months in the salvage group vs 65.9 months in the continuous treatment arm; HR, 0.80).
The lack of PFS and overall survival benefit occurred across all myeloma subgroups, Dr. Baertsch said.
Overall, the results indicate that “ a repeat transplant at the time of relapse for patients who had already gotten a transplant previously was no better than continuing a two-drug regimen,” Dr. Mohyuddin said.
However, he noted, “a lot has changed for myeloma care” since this trial was initially conducted. “We now have better regimens available that do not involve a transplant. If a repeat transplant couldn’t beat a two-drug regimen, it surely cannot beat a three drug or four drug regimen.”
Dr. Baertsch reported no disclosures.

The primary phase 3 analysis, published in 2021, showed no survival benefit following salvage transplant at the time of relapse, though it only followed patients for a median of 37 months.
However, because a significant fraction of patients in the transplant arm — about 29% — did not undergo the planned salvage transplant before dropping out of the study, the researchers performed further analyses that “suggested a survival benefit in patients who actually received the transplant,” first author Marc-Andrea Baertsch, MD, of the German Cancer Research Center and University Hospital Heidelberg, reported at ASH.
Now, the latest analysis, which followed patients for a median of 99 months (8.25 years), confirmed the initial 2021 findings, Dr. Baertsch explained.
“The writing on the wall is clear: Don’t repeat a transplant at the time of relapse for those who have already gotten a transplant,” said Manni Mohyuddin, MD, of the University of Utah in Salt Lake City, who was not involved in the research. Dr. Mohyuddin added, however, that this finding doesn’t apply to those who haven’t yet gotten a transplant. “Data from other trials suggests a role of transplant in this situation, depending on the unique circumstances.”
The current trial included 282 adult patients, aged 75 years or younger, with relapsed or refractory multiple myeloma. Between 2010 and 2016, patients in the intention-to-treat analysis (n = 277) were randomized to lenalidomide-dexamethasone reinduction and maintenance, along with salvage high-dose chemotherapy with melphalan and autologous stem cell transplantation (n = 139) or just continuous lenalidomide-dexamethasone until progression (n = 138).
Patients in both arms received three cycles of lenalidomide-dexamethasone up front: 25 mg of lenalidomide on days 1 through 21, and 40 mg of dexamethasone on days 1, 8, 15, and 22 in 4-week cycles. Those in the salvage transplant arm then received high-dose chemotherapy with 200 mg/m2 of melphalan followed by transplant and 10 mg of lenalidomide maintenance therapy daily, while those in the control arm continued with receiving lenalidomide-dexamethasone.
All patients had received one to three prior lines of therapy, had good performance status, and had a time-to-disease-progression of at least 12 months after frontline autologous stem cell transplant.
In the primary 2021 study, patients in the salvage transplant group did not demonstrate a survival benefit (hazard ratio [HR] for PFS, 0.87; HR for overall survival, 0.81).
In the latest analysis, no survival benefit emerged after following patients for a median of about 8 years. Patients in the salvage transplant arm had a median PFS of 20.5 months vs 19.3 months in the continuous therapy arms (HR, 0.98; 95% CI, 0.76-1.27; P = .9). Median overall survival was 67.1 months in the salvage transplant arm and 62.7 months in the continuous treatment arm (HR, 0.89; 95% CI, 0.66 - 1.20; P = .44).
Time to first progression after frontline transplant was associated with a PFS benefit but did not predict an overall survival benefit, Dr. Baertsch noted.
When evaluating outcomes from the time of salvage transplant to account for the high number of dropouts, the PFS and overall survival findings held. Patients who received salvage transplant did not experience significantly improved PFS (HR, 0.91) or overall survival (76.3 months in the salvage group vs 65.9 months in the continuous treatment arm; HR, 0.80).
The lack of PFS and overall survival benefit occurred across all myeloma subgroups, Dr. Baertsch said.
Overall, the results indicate that “ a repeat transplant at the time of relapse for patients who had already gotten a transplant previously was no better than continuing a two-drug regimen,” Dr. Mohyuddin said.
However, he noted, “a lot has changed for myeloma care” since this trial was initially conducted. “We now have better regimens available that do not involve a transplant. If a repeat transplant couldn’t beat a two-drug regimen, it surely cannot beat a three drug or four drug regimen.”
Dr. Baertsch reported no disclosures.

MRD status predicts transplant benefit in NPM1-mutated AML
.
This survival benefit did not extend to patients who were MRD-negative after their second induction therapy, Jad Othman, MBBS, reported at the American Society of Hematology annual meeting.
The findings confirm the value of assessing MRD after induction chemotherapy to help identify patients with NPM1-mutated AML in first complete remission who are more likely to benefit from allogeneic transplant, said Dr. Othman, of King’s College London and Guy’s and St Thomas’ NHS Foundation Trust, London, and the University of Sydney, Australia.
Recently, updated European LeukemiaNet recommendations, which stratify patients with AML by favorable, intermediate, and adverse prognoses, now include a revised genetic-risk classification. This classification generally considers NPM1-mutated AML favorable risk. However, having a co-mutation with FLT3-ITD raises the risk to intermediate.
Despite this increased granularity in risk stratification, “it’s still not really clear who should have transplant in first remission with NPM1-mutated AML,” Dr. Othman said. “And there is still significant variation in practice, not just worldwide but even center to center.”
Although accumulating evidence suggests that MRD-negative patients with intermediate-risk AML are unlikely to benefit from allogeneic transplant in first complete remission, the presence of a FLT3-ITD mutation is often considered an indication for transplant, Othman explained. However, most studies supporting this view occurred before the development of sensitive molecular MRD measurement techniques.
The latest findings, from two sequential prospective randomized trials of intensive chemotherapy in adults aged 18-60 years with newly diagnosed AML may help clarify who will probably benefit from transplant and who won’t based on MRD status and relevant molecular features.
The first study (AML17), conducted from 2009 to 2014, selected patients for transplant in first complete remission using a validated risk score that incorporated features including age, sex, and response after therapy. The other (AML19), conducted from 2015 to 2020, selected patients with NPM1-mutated AML for transplant only if they tested positive for MRD in peripheral blood after their second course of treatment, regardless of FLT3-ITD status or other baseline risk factors.
Overall, the current analysis included the 737 patients with NPM1-mutated AML, 348 from AML17 and 389 from AML19, who were in complete remission after two courses of treatment and had an MRD sample at that point.
In AML17, 27% of MRD-positive patients (16 of 60) and 18% of MRD-negative patients (52 of 288) underwent transplant in first complete remission compared with 60% (50 of 83) and 16% (49 of 306), respectively, in AML19.
Among all 737 patients, Dr. Othman and colleagues did not observe an overall survival benefit among those who underwent transplant vs those who did not (hazard ratio [HR], 1.01) or among patients who were MRD-negative (HR, 0.82).
However, patients who were MRD-positive did have a significant survival advantage after transplant (HR, 0.39). In these patients, 3-year overall survival was 61% among those who underwent transplant vs 24% among those who did not.
In MRD-negative patients, transplant in first complete remission did not improve overall survival despite improved relapse-free survival (HR, 0.50). This outcome, Othman explained, probably occurred because most patients who did not undergo transplant and who relapsed were salvaged, with about two thirds undergoing a transplant during their second complete response.
Results in patients with NPM1 FLT3-ITD co-mutation mirrored those in the overall population: MRD-positive patients in first complete remission who underwent transplant demonstrated improved overall survival compared with those without transplant (HR, 0.52), but the overall survival benefit did not extend to MRD-negative patients (HR, 0.80).
The findings show that molecular MRD after induction chemotherapy can identify patients with NPM1-mutated AML who are more likely to benefit from transplant in first remission, Dr. Othman concluded. However, he noted, because only 16% of patients overall were older than 60 years, the results may not be generalizable to older patients.

CAR T-Cell Therapy: Cure for Systemic Autoimmune Diseases?
A single infusion of autologous CD19-directed CAR T-cell therapy led to persistent, drug-free remission in 15 patients with life-threatening systemic lupus erythematosus, idiopathic inflammatory myositis, or systemic sclerosis, according to research presented at the American Society of Hematology annual meeting.
The responses persisted at 15 months median follow-up, with all patients achieving complete remission, reported Fabian Mueller, MD, of the Bavarian Cancer Research Center and Friedrich-Alexander University of Erlangen-Nuremberg, Bavaria, Germany.
The CAR T-cell treatment appears to provide an “entire reset of B cells,” possibly even a cure, for these 15 patients who had run out of treatment options and had short life expectancies, Dr. Mueller said. “It’s impressive that we have treated these patients.”
Some of the cases have been described previously — including in Annals of the Rheumatic Diseases earlier this year, Nature Medicine in 2022, and the New England Journal of Medicine in 2021.
Now with substantially longer follow-up, the investigators have gained a greater understanding of “the B-cell biology behind our treatment,” Dr. Mueller said. However, “we need longer follow-up to establish how effective the treatment is going to be in the long run.”
All 15 patients included in the analysis were heavily pretreated and had multi-organ involvement. Prior to CAR T-cell therapy, patients had a median disease duration of 3 years, ranging from 1 to as many as 20 years, and had failed a median of five previous treatments. Patients were young — a median age of 36 years — which is much younger than most oncology patients who undergo CAR T-cell therapy, Dr. Mueller said.
The 15 patients underwent typical lymphodepletion and were apheresed and treated with a single infusion of 1 x 106 CD19 CAR T cells per kg of body weight — an established safe dose used in a phase 1 trial of B cell malignancies.
The CAR T cells, manufactured in-house, expanded rapidly, peaking around day 9. B cells disappeared within 7 days and began to reoccur in peripheral blood in all patients between 60 and 180 days. However, no disease flares occurred, Dr. Mueller said.
After 3 months, eight patients with systemic lupus erythematosus showed no sign of disease activity and dramatic improvement in symptoms. Three patients with idiopathic inflammatory myositis experienced major improvements in symptoms and normalization of creatinine kinase levels, the most clinically relevant marker for muscle inflammation. And three of four patients with systemic sclerosis demonstrated major improvements in symptoms and no new disease activity. These responses lasted for a median of 15 months, and all patients stopped taking immunosuppressive drugs.
Patients also tolerated the CAR T-cell treatment well, especially compared with the adverse event profile in oncology patients. Only low-grade inflammatory CAR T-related side effects occurred, and few patients required support for B-cell-derived immune deficiency.
However, infectious complications occurred in 14 patients, including urinary tract and respiratory infections, over the 12-month follow-up. One patient was hospitalized for severe pneumonia a few weeks after CAR T therapy, and two patients experienced herpes zoster reactivations, including one at 6 months and one at 12 months following treatment.
During a press briefing at the ASH conference, Dr. Mueller addressed the “critical question” of patient selection for CAR T-cell therapy, especially in light of the recently announced US Food and Drug Administration investigation exploring whether CAR T cells can cause secondary blood cancers.
Although the T-cell malignancy risk complicates matters, CAR T cells appear to behave differently in patients with autoimmune diseases than those with cancer, he said.
“We don’t understand the biology” related to the malignancy risk yet, Dr. Mueller said, but the benefit for end-of-life patients with no other treatment option likely outweighs the risk. That risk-benefit assessment, however, is more uncertain for those with less severe autoimmune diseases.
For now, it’s important to conduct individual assessments and inform patients about the risk, Dr. Mueller said.
Dr. Mueller disclosed relationships with BMS, AstraZeneca, Gilead, Janssen, Miltenyi Biomedicine, Novartis, Incyte, Abbvie, Sobi, and BeiGene.

Iptacopan, a factor B inhibitor, offers “superior hemoglobin improvement in the absence of transfusions” in patients with this rare chronic blood disorder, according to a Novartis press release.
“An efficacious oral treatment with a demonstrated safety profile could be practice-changing for physicians and help relieve burdens experienced by people with PNH,” Vinod Pullarkat, MD, of City of Hope Cancer Center, Duarte, California, said in the company press release.
Previously, the only approved treatments for PNH were injectable C5 complement inhibitors.
The latest approval was based on the randomized, open-label, phase 3 APPLY-PNH trial in 97 adults with PNH and anemia and was supported by safety and efficacy findings from the phase 3, single-arm APPOINT-PNH study in 40 C5 complement inhibitor–naive patients.
APPLY-PNH participants included adults with residual anemia receiving a stable regimen of anti-C5 treatment in the prior 6 months. Patients were randomly assigned to switch to 200 mg of iptacopan (n = 62) given twice daily or to remain on the anti-C5 therapy (n = 35).
The investigators reported greater increases in hemoglobin levels in patients who switched to iptacopan, with sustained increases ≥ 2 g/dL in 82.3% compared with 0% of patients who did not switch. Investigators also observed increases ≥ 12 g/dL in 67.7% of patients who switched vs 0% of those who did not. Almost all patients (95.2%) in the iptacopan group avoided a red blood cell transfusion vs 45.7% among patients who did not switch.
In the APPLY-PNH trial, common adverse reactions with iptacopan vs anti-C5 therapy included headache(19% vs 3%), nasopharyngitis (16% vs 17%), diarrhea (15% vs 6%), abdominal pain (15% vs 3%), bacterial infection(11% vs 11%), nausea (10% vs 3%), and viral infection(10% vs. 31%). Two patients experienced serious adverse events, which included pyelonephritis, urinary tract infection, and COVID-19.
In the APPOINT-PNH trial, the most common adverse events were headache (28%), viral infection (18%), nasopharyngitis (15%), and rash (10%). Serious adverse events, reported in two patients (5%), included COVID-19 and bacterial pneumonia.
“Fabhalta may cause serious infections caused by encapsulated bacteria and is available only through a Risk Evaluation and Mitigation Strategy (REMS) that requires vaccinations for encapsulated bacteria,” Novartis cautioned.

How to address chemo-related amenorrhea in early breast cancer to help improve quality of life
in a large multicenter French cohort study.
The findings, which showed a particularly increased risk of persistent CRA in older women and those who received adjuvant tamoxifen, can help inform communication, personalized counseling, and supportive care, according to the investigators.
At 1 year after treatment, CRA occurred in 1242 of 1497 women (83.0%) from the prospective, longitudinal Cancers Toxicity Study (CANTO). The rates at years 2 and 4 after treatment were 72.5% and 66.1%, respectively, Rayan Kabirian, MD, of Gustave Roussy, Villejuif, France, and Sorbonne University, Paris, and colleagues reported.
In a quality-of-life analysis conducted among 729 women from the cohort, 416 (57.1%) had persistent CRA, although 11 of 21 women aged 18-34 years who had no menses at year 2 had late menses recovery between years 2 and 4. Those with persistent CRA at year 4, compared with those who had menses recovery at any time, had significantly worse insomnia (mean difference, 9.9 points), worse systemic therapy-related adverse effects (mean difference, 3.0 points), and worse sexual functioning (mean difference, -9.2 points).
Factors associated with greater risk of persistent CRA included receipt versus non-receipt of adjuvant tamoxifen (adjusted odds ratio, 1.97), and hot flashes at diagnosis (aOR, 1.83, and older age versus age 18-34 (aORs, 1.84 for those aged 35-39 years; 5.90 for those aged 40-44 years, and 21.29 for those 45 or older).
The findings were published online November 16 in JAMA Network Open.
The study cohort included 1636 women under age 50 years (mean age of 42.2 years) at the time of diagnosis of stage I to III breast cancer. Outcomes at up to 4 years after diagnosis and enrollment between 2012 and 2017 were reported. QOL was assessed using the European Organization for Research and Treatment of Cancer (EORTC) QOL questionnaires c30 and br23.
“Breast cancer is the most commonly diagnosed tumor in women, and approximately 20% of women with breast cancer are younger than 50 years at diagnosis,” the investigators note, explaining that younger survivors have higher risk of cancer-related symptoms and quality-of-life deterioration. “In particular, treatment-related symptoms linked to the menopausal transition (ie, vasomotor symptoms and sexual problems) represent an important source of distress during and after treatment, highlighting a need to monitor and address survivorship-related problems that are specific to this population.”
The current analysis “helps answer several clinical questions about long-term trajectories of CRA and menses recovery rates by age and about factors associated with higher likelihood of CRA,” they added, noting that the findings have several clinical implications.
For example, premenopausal women should be made aware of the risks associated with chemotherapy-related premature ovarian failure and persistent CRA, and should and receive systematic oncofertility counseling, they argue.
“In addition, in light of data showing possible late [menses] recoveries, contraceptive options should also be clearly discussed,” and “[d]edicated gynecological counseling may help patients who have an inaccurate perception of infertility due to previous exposure to chemotherapy and long-term absence of menses.”
Given that a late menses recovery pattern was also observed in older age groups in the cohort, the investigators noted that choosing the optimal adjuvant endocrine treatment can pose a challenge.
“The absence of menses after completion of chemotherapy should not be used as a proxy for permanent transition to menopause, because it does not represent a reliable surrogate of gonadotoxicity,” they warned. “Adjuvant endocrine treatment choices should be based on a more thorough and comprehensive evaluation, combining absence of menses, assessments of circulating hormone levels, and gynecological ultrasonographic imaging.”
These findings “can inform personalized care pathways targeting patients at higher risk of QOL deterioration associated with a permanent menopausal transition,” they noted, concluding that “[r]isk and duration of CRA, including potential late resumption of menses and its downstream implications for QOL, should be approached using a coordinated biopsychosocial model addressing multiple dimensions of physical, psychological, and social health.
“Proactive management of premenopausal women with early breast cancer undergoing chemotherapy should also include adapted strategies for risk communication, as well as personalized counseling and early supportive care referrals.”
