SAN DIEGO — Final results of the phase 3 Andromeda study confirmed that adding daratumumab (DARA) — a human CD38-targeting monoclonal antibody — to bortezomib, cyclophosphamide, and dexamethasone (VCd) improves outcomes in patients with newly diagnosed amyloid light chain (AL) amyloidosis.

Adding DARA to VCd (D-VCd; Darzalex Faspro; Janssen Biotech) provided deeper and more rapid hematologic response and clinically meaningful and statistically significant improvement in overall survival (OS) and major organ deterioration progression-free survival (MOD-PFS), combined with 40.7% cardiac complete response (CR), first author Efstathios Kastritis, MD, said during presentation of an oral abstract at the American Society of Hematology (ASH) 2024 Annual Meeting.

“The Andromeda study is the first comparing two contemporary regimens that shows a significant survival improvement for patients with AL amyloidosis,” said Kastritis, an associate professor at the National and Kapodistrian University of Athens in Greece. “These findings reaffirm frontline D-VCd as the standard of care in this difficult-to-treat disease.”

The regimen was approved for this indication in 2021 based on prior earlier findings from the Andromeda trial. The current results are from a preplanned analysis for MOD-PFS and OS.

At a median follow-up of 61.4 months, the overall hematologic CR rates were 59.5% and 19.2% among 388 patients randomized to receive D-VCd or VCd, respectively (odds ratio, 6.03), which showed continued improvement with additional DARA vs the 53.3% and 18.1% rates observed at the primary analysis, Kastritis reported.

Time to hematologic CR was 67.5 days and 85.0 days in the treatment groups, respectively, and median duration of hematologic CR was not reached in either group.

A significant 56% improvement was also observed in MOD-PFS (hazard ratio [HR], 0.44). Median MOD-PFS was not reached in the D-VCd group and was 30.3 months in the VCd group.

A significant 38% improvement was observed in OS (HR, 0.62), 5-year OS was 76.1% vs 64.7% in the D-VCd and VCd groups, respectively, he said.

“[The OS] benefit occurred even though more than 70% of the patients in the VCd arm who received a subsequent therapy were treated with a DARA-based regimen,” he stressed. “This further emphasizes the importance of using DSTS in the frontline setting.”

Trial participants had newly diagnosed AL amyloidosis with measurable hematologic disease, one or more involved organs, cardiac stage I-IIIA, estimated glomerular filtration rate of at least 20 mL/min, and absence of symptomatic multiple myeloma. They were randomized 1:1 to the two treatment groups. All patients received 1.3 mg/m2 of bortezomib by weekly injection, 300 mg/m2 of cyclophosphamide either by weekly oral or intravenous administration, and 20-40 mg of dexamethasone by weekly oral or intravenous administration for six 28-day cycles.

Those in the D-VCd group also received 1800 mg of DARA coformulated with rHuPH20 as a weekly injection in cycles 1-2, as a biweekly injection in cycles 3-6, and by injection every 4 weeks thereafter for up to 24 28-day cycles.

The median duration of treatment was 21.3 months for D-VCd and 5.3 months for VCd, and of 122 patients who received subsequent therapy, 82 (67%) received subsequent DARA.

Patients who achieved hematologic CR had better MOD-PFS and OS (HR, 0.30 and 0.41, respectively), regardless of the treatment received, he noted, adding that “this further supports that complete hematologic response is a valid early endpoint for the evaluation of anti-monoclonal therapies in AL amyloidosis.”

“I think this is very important for the further development of new treatments in this disease,” he said.

Of note, cardiac and renal response rates in the D-VCd group were about two to three times greater than those in the VCd group at 6, 12, 24, 36, and 48 months, Kastritis said.

Among 235 patients with an evaluable cardiac response, 113 achieved a very good partial response or better, including 76 of 118 (64.4%) in the D-VCd group and 37 of 117 (31.6%) in the VCd group. Of these, 48 (40.7%) and 16 (13.7%) achieved a cardiac CR.

Grade 3 or 4 treatment-emergent adverse events (TEAEs) occurring in at least 5% of patients in the D-VCd and VCd groups, respectively, were lymphopenia (13% and 10%), pneumonia (8% and 4%), hypokalemia (2% and 5%), and peripheral edema (3% and 6%), he noted, adding that systemic administration-related reactions occurred in 14 (7%) of patients receiving D-VCd; all were grade 1 or 2 and most (86%) occurred after the first injection. TEAEs led to treatment discontinuation in 5% and 4% of patients in the groups, respectively.

No new safety signals were observed during the extended follow-up, he said.

Kastritis reported relationships with Pfizer, Genesis Pharma, Sanofi, AbbVie, GSK, Prothena, Janssen, and Amgen.

Children with newly diagnosed immune thrombocytopenia (ITP) treated with eltrombopag as a frontline therapy show significantly improved platelet responses and other outcomes compared with the standard of care.

“This is the first time in 30 years that a new drug is being tested for newly diagnosed pediatric ITP,” said the study’s lead author, Kristin A. Shimano, MD, professor of pediatrics at the Benioff Children’s Hospital, University of California San Francisco, in a press statement for the study, presented at the American Society of Hematology (ASH) 2024 Annual Meeting earlier this month.

“We really think that this has the potential to transform the approach to the management of ITP in the newly diagnosed phase with the use of a therapy that can provide sustained hemostatic platelet counts to bridge the time that patients are at risk of bleeding events with the goal to wean off the medication for patients who have a natural resolution of their disease,” Shimano said in her talk.

While children with ITP, a rare autoimmune blood disorder, very often improve without the need for any treatment, some do require intervention, and the condition can become chronic. First-line therapies for those patients commonly include corticosteroids, intravenous immunoglobulin (IVIg), and anti-D globulin; however, side effects can be undesirable, and with their efficacy often temporary, patients can require monitoring and juggling of treatments.

Eltrombopag, an oral, daily thrombopoietin receptor agonist, was approved by the US Food and Drug Administration for children and adults with chronic ITP in 2015; however, research has been lacking on the benefits of the therapy for newly diagnosed pediatric patients.

To investigate the drug’s efficacy at that stage, Shimano and colleagues with the ITP Consortium of North America launched the prospective, open-label Pediatric ITP Newly diagnosed pts Epag vs Standard therapy (PINES) trial, enrolling 118 patients at 23 institutions between May 2019 and January 2024.

All enrollees had been diagnosed with ITP within 3 months and had been determined by their treating hematologist to require pharmacologic treatment.

Of the patients, about 40% were untreated, and 60% had been treated with at least one medication prior to the trial but did not have a lasting response.

The patients were stratified by age and prior treatment and randomized 2:1 to receive either eltrombopag (n = 78) or the investigator’s choice of one of three standard first-line therapies, including prednisone, IVIg, or anti-D globulin at specified doses (n = 40). Overall, 29 in the standard-of-care arm received prednisone and 11 received IVIg. The patients had a median age of 8 years.

For the study’s primary endpoint, patients in the eltrombopag group had a significantly greater sustained response at 12 weeks, defined as having at least three of four platelet counts > 50 × 109/L during weeks 6-12 without the need for rescue treatment, with a rate of 63% vs 35% in the standard-of-care group (P = .0054).

There were no significant differences between the two groups in terms of the proportion of patients with a high bleeding score at weeks 1-4 and week 12.

However, those in the eltrombopag arm had a significantly lower rate of receiving rescue therapy (18% vs 38% with the standard of care; P = .02).

Both groups showed clinically meaningful improvements from baseline in terms of health-related quality of life, as assessed by parent proxy-reported KIT overall scores.

Twenty adverse events that were grade 3 or higher, including six serious adverse events, occurred in each of the study’s arms, with the most common events including headache and epistaxis.

Treatment-related serious adverse events occurred among six patients in the eltrombopag group and one in the control group, but importantly, no thromboembolic events were reported.

One intracranial hemorrhage occurred in the eltrombopag arm.

With eltrombopag having a slower effect than some other treatments, Shimano cautioned that the therapy is not recommended for patients with severe bleeding.

“Patients with grade 4 or 5 bleeding at the time of screening were specifically excluded from the study, so for patients who have very severe bleeding who need to get their platelets up very quickly, this would not be the ideal therapy for them,” she noted.

On the basis of results, the trial was recommended to close early due to efficacy; however, the participants are being followed for a total of 12 months to determine the durability of the responses, including in terms of bleeding events, quality of life, or the development of chronic ITP.

“We have shown that in pediatric patients with newly diagnosed ITP requiring pharmacologic treatment, eltrombopag resulted in a significant, clinically relevant higher rate of a durable platelet response in the absence of rescue treatment as compared with standard first-line therapies,” Shimano said.

“Eltrombopag could certainly be added to the medication choices hematologists consider as they are making treatment decisions with families, and it is an option that could potentially raise platelets for a more sustained period in children with ITP in the newly diagnosed period, which is one of the most difficult times for patients with regard to the impact of the disease on bleeding symptoms and quality of life,” she added.

Commenting on the study, James B. Bussel, MD, emeritus professor of pediatrics, medicine and obstetrics and gynecology at Weill Cornell Medicine in New York City, commented that “generally, a short-term increase in platelets is the biggest challenge, which is getting the patient to the point of not requiring future treatment to get better.”

“If more children can be shown to be going into remission earlier, that would be great,” he said.

While eltrombopag is known to be effective in chronic ITP, a key caveat of its use in newly diagnosed patients is the question of whether patients will get better on their own and feasibly be able to be spared the cost and burden of treatment in the first place.

However, identifying which patients will fit that profile isn’t always easy.

“Exactly which child needs treatment can be hard to determine, and there is some debate about that,” Bussel noted.

“The theoretic standard is that the platelet count doesn’t matter — only whether the patient is bleeding a lot, and then there is debate over treatment based on bleeding scores,” he said.

Quality-of-life issues, such as patients’ ability to take part in activities, are also a key consideration.

“It would be great if eltrombopag can support children who really need it and provide clear unequivocal benefit beyond just increasing the platelet count, but also leading to better quality of life,” Bussel said.

The new findings are “a very encouraging start, but I’d really like to see what the story is at 1 year.”

The study was funded by Novartis, maker of eltrombopag, and sponsored by the ITP Consortium of North America. Shimano disclosed ties with Sanofi, Sobi, Daiichi Sankyo, Novartis, and Pfizer. Bussel reported a relationship with Novartis that ended more than 2 years ago.

“Patients with grade 4 or 5 bleeding at the time of screening were specifically excluded from the study, so for patients who have very severe bleeding who need to get their platelets up very quickly, this would not be the ideal therapy for them,” she noted.

On the basis of results, the trial was recommended to close early due to efficacy; however, the participants are being followed for a total of 12 months to determine the durability of the responses, including in terms of bleeding events, quality of life, or the development of chronic ITP.

“We have shown that in pediatric patients with newly diagnosed ITP requiring pharmacologic treatment, eltrombopag resulted in a significant, clinically relevant higher rate of a durable platelet response in the absence of rescue treatment as compared with standard first-line therapies,” Shimano said.

“Eltrombopag could certainly be added to the medication choices hematologists consider as they are making treatment decisions with families, and it is an option that could potentially raise platelets for a more sustained period in children with ITP in the newly diagnosed period, which is one of the most difficult times for patients with regard to the impact of the disease on bleeding symptoms and quality of life,” she added.

Commenting on the study, James B. Bussel, MD, emeritus professor of pediatrics, medicine and obstetrics and gynecology at Weill Cornell Medicine in New York City, commented that “generally, a short-term increase in platelets is the biggest challenge, which is getting the patient to the point of not requiring future treatment to get better.”

“If more children can be shown to be going into remission earlier, that would be great,” he said.

While eltrombopag is known to be effective in chronic ITP, a key caveat of its use in newly diagnosed patients is the question of whether patients will get better on their own and feasibly be able to be spared the cost and burden of treatment in the first place.

However, identifying which patients will fit that profile isn’t always easy.

“Exactly which child needs treatment can be hard to determine, and there is some debate about that,” Bussel noted.

“The theoretic standard is that the platelet count doesn’t matter — only whether the patient is bleeding a lot, and then there is debate over treatment based on bleeding scores,” he said.

Quality-of-life issues, such as patients’ ability to take part in activities, are also a key consideration.

“It would be great if eltrombopag can support children who really need it and provide clear unequivocal benefit beyond just increasing the platelet count, but also leading to better quality of life,” Bussel said.

The new findings are “a very encouraging start, but I’d really like to see what the story is at 1 year.”

The study was funded by Novartis, maker of eltrombopag, and sponsored by the ITP Consortium of North America. Shimano disclosed ties with Sanofi, Sobi, Daiichi Sankyo, Novartis, and Pfizer. Bussel reported a relationship with Novartis that ended more than 2 years ago.

SAN DIEGO — The multiple myeloma (MM) drug daratumumab (Darzalex), an anti-CD38 monoclonal antibody, dramatically reduced progression to active MM or death in patients with high-risk smoldering MM (SMM), a landmark randomized, open-label, phase 3 study found.

Among 390 patients with SMM (194 assigned to daratumumab and 196 to active monitoring), progression to active MM or death over a follow-up of 65.2 (0-76.6) months was 51% lower in the daratumumab group vs active monitoring (34.5% vs 50.5%, hazard ratio [HR], 0.49; 95% CI, 0.36-0.67; P < .0001), researchers reported at the American Society of Hematology (ASH) 2024 Annual Meeting and in a simultaneous publication in the New England Journal of Medicine.

Rahul Banerjee, MD, an assistant professor with the University of Washington and Fred Hutchinson Cancer Center, both in Seattle, who wasn’t involved with the research, said the study “is a big deal, and I suspect this will ultimately lead to an FDA [Food and Drug Administration] approval for daratumumab in this setting. If using daratumumab up-front can prevent further myeloma and therefore make patients live longer, this would be immediately adopted at many practices.”

As study first author Meletios Athanasios Dimopoulos, MD, of National and Kapodistrian University of Athens and Alexandra General Hospital in Greece, noted at a news briefing, SMM is common, affecting 0.5% of the population aged over 40, per a 2023 Iceland study.

“Standard practice is close follow-up without immediate intervention. However, this oftentimes ends in organ tissue damage, and hypercalcemia, bone lesions, renal impairment, and anemia,” Dimopoulos said.

According to him, researchers launched the AQUILA study in light of indications that daratumumab may benefit patients with intermediate- and high-risk SMM.

For the study, researchers recruited patients from 2017 to 2019 in 23 countries with confirmed high-risk SMM for ≤ 5 years (median age, 64 [31-86] years; 47%-49% men; 83% White).

In the daratumumab group, the drug was administered in 28-day cycles until cycle 39, 36 months, or disease progression, whichever came first (median treatment duration, 38 months [35 months]).

At 5 years, progression-free survival (PFS) — the primary endpoint — was 63.1% (daratumumab) and 40.8% (active monitoring). Researchers estimated 60-month PFS rates at 63.1% and 40.8%, respectively, and overall response rates were 63.4% vs 2.0% (P < .0001), respectively.

The 60-month overall survival rates were 93.0% and 86.9% (HR, 0.52; 95% CI, 0.27-0.98) with 15 deaths in the daratumumab and 26 in the active monitoring group.

“During the follow-up period, there was continuous improvement in favor of the daratumumab arm,” Dimopoulos said. “Even after treatment was discontinued at 3 years, or even at 5 or 6 years, there was a continuous benefit from treatment with daratumumab.”

By clinical cutoff in May 2024, 65% of patients taking daratumumab had finished 39 cycles/3 years of treatment vs 40.8% in the active monitoring group. Progressive disease was the most common reason that patients stopped treatment (21.8% and 41.8% of patients in the groups, respectively).

Grade 3/4 treatment-emergent adverse events (TEAEs) occurred in 40.4% (daratumumab) and 30.1% (active monitoring) of patients. The most common was hypertension (5.7% and 4.6%, respectively).

In the daratumumab group, 5.7% discontinued therapy because of TEAEs, which the researchers described as a “low” number, and fatal TEAEs were similar in both groups (1.0% and 2.0%, respectively).

Banerjee said that “one theoretical risk of using daratumumab monotherapy to treat perceived high-risk SMM is that if the patient actually has active multiple myeloma, you are undertreating them. For anyone with HR-SMM, active multiple myeloma must be completely ruled out. I always insist on both a PET-CT and a whole-body MRI to evaluate the bone marrow comprehensively.”

For now, Banerjee said, clinicians should wait for the US Food and Drug Administration approval before prescribing daratumumab for high-risk SMM.

Are there alternatives to reduce the risk for SMM turning into MM? “Generally, I advise close observation in most cases, but we do have clinical trials in this space,” Banerjee said. “Technically, it is possible to consider lenalidomide monotherapy in SMM based on the results of a large phase 3 study. But lenalidomide is expensive and has many side effects. Insurance companies often won’t cover it fully, and patients almost always have at least one side effect.”

Also, he added, “only half of patients saw their high-risk SMM disease burden drop. Lenalidomide also has a clear link to rare, delayed toxicities such as second primary malignancies, which makes us nervous.”

Janssen Pharmaceuticals, the maker of daratumumab, funded the study. Dimopoulos disclosed ties with Sanofi, Regeneron, Menarini, Takeda, GSK, BMS, Janssen Pharmaceuticals, BeiGene, Swixx, AstraZeneca, and Amgen. Banerjee disclosed ties with AbbVie, Adaptive, BMS, Caribou, Genentech/Roche, GSK, Karyopharm Therapeutics, Legend, Johnson & Johnson, Novartis, Pack, Pfizer, Prothena, Sanofi Pasteur, and SparkCures. Some other authors reported various and multiple disclosures, including ties with Janssen Pharmaceuticals.

Treated with a dexamethasone-sparing regimen, frail older adult patients with newly diagnosed multiple myeloma (MM) show significant reductions in disease progression and improvements in quality of life, new research shows.

The study “is the first randomized phase 3 study dedicated to frail patients,” said first author Salomon Manier, MD, PhD, an associate professor of hematology at Lille University Hospital, Lille, France. He presented the findings this week at the American Society of Hematology (ASH) 2024 Annual Meeting in San Diego.

“It shows that daratumumab-lenalidomide [with limited dexamethasone] led to a significant reduced risk of progression or death by 49% in frail patients, with a favorable safety profile and an improved health-related quality of life,” Manier said.

Older adult patients who are newly diagnosed with MM have varying levels of fitness or frailty and have been shown to have shorter survival, with higher rates of nonhematologic adverse events and treatment discontinuation.

While the regimen of daratumumab, lenalidomide, and dexamethasone has become a standard of care, with efficacy and tolerance, including for patients with frailty, the infection and pneumonia rates with the approach can be high, particularly for patients with frailty.

To evaluate if an alternative, dexamethasone-sparing approach could improve outcomes while limiting toxicity for older adults, Manier and his colleagues conducted the prospective, open-label phase 3 IFM2017-03 trial, involving 295 patients (age, 65 years) with newly diagnosed MM at 90 centers in France.

The patients had a median age of 81, with 84% older than 75 years and 61% older than 80 years. All had an Eastern Cooperative Oncology Group proxy frailty score ≥ 2.

The patients were randomized 1:2 to treatment either with the Rd regimen of 28-day cycles of lenalidomide (25 mg/d, 21/28) and dexamethasone (20 mg once weekly) or with the dexamethasone-sparing regimen (DR) of daratumumab (1800 mg subcutaneous once weekly for 8 weeks, once every 2 weeks for 16 weeks, and once every 4 weeks thereafter), lenalidomide (25 mg/d, 21/28), and two cycles of dexamethasone (20 mg once weekly for 8 weeks then stopping).

The randomization included stratification based on age and cancer stage. Baseline characteristics were well balanced in the two groups.

Both regimens were administered until disease progression or unacceptable toxicity.

As of the data cut-off in November 2024, with a median follow-up of 46.3 months, 81 of the original 200 patients in the DR arm remained on treatment, and 11 of 95 continued in the Rd arm.

The overall median treatment duration among the 200 original patients in the DR arm was 31.6 months and 14.3 months in the Rd arm.

The study met its primary endpoint of progression-free survival (PFS), with a median rate of 53.4 months in the DR arm vs 22.5 months in the Rd arm (hazard ratio [HR], 0.51; P < .0001).

The improved PFS in the DR arm was observed across all subgroups based on age, Charlson comorbidity index, cancer stage, cytogenetics, and creatinine clearance; however, those with lower frailty scores had better outcomes in both groups.

A median overall survival was not reached in the DR arm vs 47.2 months in the Rd arm (HR, 0.52; P = .0001).

The DR arm also showed a higher overall best response rate of 94% vs 86% (P = .005), respectively, with deeper responses in the DR arm at all time points, including the earliest points at 4 months.

In terms of adverse events (AEs), at least one AE of grade ≥ 3 occurred in 89% in the DR arm and 79% in the Rd arm.

Those in the DR arm had significantly more grade 3 or higher hematologic AEs with neutropenia (62% vs 34%); however, grade ≥ 3 infections were similar, with 19% in the DR arm and 21% in the Rd arm. Infections involving pneumonia occurred in 6% and 8%, respectively.

There were no significant differences between the two arms in discontinuations due to AEs (30% in the DR arm and 34% in the Rd arm).

While health-related quality of life measures at baseline were well balanced between the two groups, those in the DR arm reported significantly shorter times to clinically meaningful improvement in all domains of the EORTC Core Quality of Life questionnaire (EORTC QLQ-C30).

“The safety profile was significantly improved and was favorable, without increased infection or pneumonia rates, with similar rates of treatment discontinuation,” Manier said.

Based on the findings, “we believe that the dexamethasone-sparing strategy is effective and safe for treating these frail patients with multiple myeloma,” he added.

Commenting on the study, Manni Mohyuddin, MD, an assistant professor in the multiple myeloma program at the Huntsman Cancer Institute, University of Utah, Salt Lake City, noted that, with the popularity of triplet regimens such as daratumumab, lenalidomide, and dexamethasone, the Rd regimen in the study is not as commonly used.

“But what this trial tells us is that efficacy outcomes in such a group of patients are encouraging despite getting rid of dexamethasone so quickly,” he said in an interview.

However, “while the tide is changing, dexamethasone is still given long-term, week after week after week in most myeloma protocols and in the community,” he noted. “Hopefully, this trial, and some of the other work, will lead to a change in this space.” 

Mohyuddin suggests one approach can involve starting off with just daratumumab and a low dose of dexamethasone, then adding lenalidomide at a lower dose later in a sequential/graded approach.

“Other approaches that should be studied should be bispecific antibodies used sparingly, with less frequent dosing, or finite period,” he added. “There is lot to refine.”

Mohyuddin added a critique that the study’s endpoint of PFS may not have been ideal for the population of elderly and frail patients.

“Older people generally prioritize functional independence and quality of life, and perhaps a more patient-centered endpoint could have led to an even more informative study,” he said.

Manier’s disclosures included consultancy with Takeda Pharmaceuticals, Sanofi, Novartis, Janssen, GlaxoSmithKline, Celgene/BMS, Amgen, Adaptive Biotechnologies, Roche, Regeneron, and AbbVie. Mohyuddin had no disclosures.

“It shows that daratumumab-lenalidomide [with limited dexamethasone] led to a significant reduced risk of progression or death by 49% in frail patients, with a favorable safety profile and an improved health-related quality of life,” Manier said.

Older adult patients who are newly diagnosed with MM have varying levels of fitness or frailty and have been shown to have shorter survival, with higher rates of nonhematologic adverse events and treatment discontinuation.

While the regimen of daratumumab, lenalidomide, and dexamethasone has become a standard of care, with efficacy and tolerance, including for patients with frailty, the infection and pneumonia rates with the approach can be high, particularly for patients with frailty.

To evaluate if an alternative, dexamethasone-sparing approach could improve outcomes while limiting toxicity for older adults, Manier and his colleagues conducted the prospective, open-label phase 3 IFM2017-03 trial, involving 295 patients (age, 65 years) with newly diagnosed MM at 90 centers in France.

The patients had a median age of 81, with 84% older than 75 years and 61% older than 80 years. All had an Eastern Cooperative Oncology Group proxy frailty score ≥ 2.

The patients were randomized 1:2 to treatment either with the Rd regimen of 28-day cycles of lenalidomide (25 mg/d, 21/28) and dexamethasone (20 mg once weekly) or with the dexamethasone-sparing regimen (DR) of daratumumab (1800 mg subcutaneous once weekly for 8 weeks, once every 2 weeks for 16 weeks, and once every 4 weeks thereafter), lenalidomide (25 mg/d, 21/28), and two cycles of dexamethasone (20 mg once weekly for 8 weeks then stopping).

The randomization included stratification based on age and cancer stage. Baseline characteristics were well balanced in the two groups.

Both regimens were administered until disease progression or unacceptable toxicity.

As of the data cut-off in November 2024, with a median follow-up of 46.3 months, 81 of the original 200 patients in the DR arm remained on treatment, and 11 of 95 continued in the Rd arm.

The overall median treatment duration among the 200 original patients in the DR arm was 31.6 months and 14.3 months in the Rd arm.

The study met its primary endpoint of progression-free survival (PFS), with a median rate of 53.4 months in the DR arm vs 22.5 months in the Rd arm (hazard ratio [HR], 0.51; P < .0001).

The improved PFS in the DR arm was observed across all subgroups based on age, Charlson comorbidity index, cancer stage, cytogenetics, and creatinine clearance; however, those with lower frailty scores had better outcomes in both groups.

A median overall survival was not reached in the DR arm vs 47.2 months in the Rd arm (HR, 0.52; P = .0001).

The DR arm also showed a higher overall best response rate of 94% vs 86% (P = .005), respectively, with deeper responses in the DR arm at all time points, including the earliest points at 4 months.

In terms of adverse events (AEs), at least one AE of grade ≥ 3 occurred in 89% in the DR arm and 79% in the Rd arm.

Those in the DR arm had significantly more grade 3 or higher hematologic AEs with neutropenia (62% vs 34%); however, grade ≥ 3 infections were similar, with 19% in the DR arm and 21% in the Rd arm. Infections involving pneumonia occurred in 6% and 8%, respectively.

There were no significant differences between the two arms in discontinuations due to AEs (30% in the DR arm and 34% in the Rd arm).

While health-related quality of life measures at baseline were well balanced between the two groups, those in the DR arm reported significantly shorter times to clinically meaningful improvement in all domains of the EORTC Core Quality of Life questionnaire (EORTC QLQ-C30).

“The safety profile was significantly improved and was favorable, without increased infection or pneumonia rates, with similar rates of treatment discontinuation,” Manier said.

Based on the findings, “we believe that the dexamethasone-sparing strategy is effective and safe for treating these frail patients with multiple myeloma,” he added.

Commenting on the study, Manni Mohyuddin, MD, an assistant professor in the multiple myeloma program at the Huntsman Cancer Institute, University of Utah, Salt Lake City, noted that, with the popularity of triplet regimens such as daratumumab, lenalidomide, and dexamethasone, the Rd regimen in the study is not as commonly used.

“But what this trial tells us is that efficacy outcomes in such a group of patients are encouraging despite getting rid of dexamethasone so quickly,” he said in an interview.

However, “while the tide is changing, dexamethasone is still given long-term, week after week after week in most myeloma protocols and in the community,” he noted. “Hopefully, this trial, and some of the other work, will lead to a change in this space.” 

Mohyuddin suggests one approach can involve starting off with just daratumumab and a low dose of dexamethasone, then adding lenalidomide at a lower dose later in a sequential/graded approach.

“Other approaches that should be studied should be bispecific antibodies used sparingly, with less frequent dosing, or finite period,” he added. “There is lot to refine.”

Mohyuddin added a critique that the study’s endpoint of PFS may not have been ideal for the population of elderly and frail patients.

“Older people generally prioritize functional independence and quality of life, and perhaps a more patient-centered endpoint could have led to an even more informative study,” he said.

Manier’s disclosures included consultancy with Takeda Pharmaceuticals, Sanofi, Novartis, Janssen, GlaxoSmithKline, Celgene/BMS, Amgen, Adaptive Biotechnologies, Roche, Regeneron, and AbbVie. Mohyuddin had no disclosures.

Glucagon-like peptide 1 (GLP-1) receptor agonists led to a significant reduction in the risk for venous thromboembolism (VTE) among individuals with type 2 diabetes, compared with dipeptidyl peptidase 4 (DPP-4) inhibitors, a recent analysis indicated.

Overall, GLP-1 agonist use was associated with a 20% reduction in VTE, compared with DPP-4 inhibitor use, in those with type 2 diabetes, and this benefit held regardless of people’s obesity status, said study investigator Cho-Han Chiang, MD, a medical resident at Mount Auburn Hospital, Cambridge, Massachusetts, who presented the findings at the American Society of Hematology (ASH) 2024 Annual Meeting.

The incidence of VTE has increased by 20% over the past 10 years, and obesity is a risk factor for VTE, Chiang explained. A growing body of evidence demonstrated that GLP-1s provide a variety of cardiovascular benefits in people with type 2 diabetes, but data on VTE benefits remain more limited.

In the retrospective study, the researchers combed electronic health records from the TriNetX global database, which includes more than 250 million patients, and identified adults with type 2 diabetes who were taking a GLP-1 agonist or a DPP-4 inhibitor.

After excluding anyone with prior VTE or atrial fibrillation as well as those treated with both drugs or with oral anticoagulants, patients on GLP-1s were matched with those on DPP-4 inhibitors based on predetermined variables, including age, sex, race, body mass index (BMI), hemoglobin A1c, use of other antidiabetic agents, and underlying comorbidities. VTE was a composite of pulmonary embolism and deep vein thrombosis.

The researchers also performed a subgroup analysis that stratified patients by obesity status, defined as a BMI ≥ 30.

Within 1 year of GLP-1 or DPP-4 prescription, VTE occurred at a rate of 6.5 cases/1000 person-years in the GLP-1 group vs 7.9 cases/1000 person years in the DPP-4 inhibitor group (hazard ratio [HR], 0.80; P < .001).

The 20% risk reduction in VTE held across various subgroups of BMI, including among those with obesity, Chiang reported.

Among patients with the highest BMI (≥ 40), VTE occurred at a rate of 7.2 cases/1000 person years in the GLP-1 group vs 9.6 cases/1000 person years in the DPP-4 inhibitor group (HR, 0.74). Among patients with the next highest BMI (30-34.9), VTE occurred at a rate of 4.8 cases/1000 person years in the GLP-1 group vs 7.9 cases/1000 person years in the DPP-4 inhibitor group (HR, 0.60). Among those with the lowest BMI (18.5-24.9), VTE occurred significantly less frequently among those in the GLP-1 group — 4.7 cases/1000 person years vs 7.4 cases/1000 person years in the DPP-4 inhibitor group (HR, 0.61).

The lower risk for VTE associated with GLP-1s also held across the individual components of the composite VTE. Pulmonary embolism occurred at a rate of 3.1 cases/1000 person years in the GLP-1 group vs 3.9 cases/1000 person years in the DPP-4 inhibitor group (HR, 0.78), and deep vein thrombosis occurred in 4.2 cases/1000 person years in the GLP-1 group vs 5.0 cases/1000 person years in the DPP-4 inhibitor group (HR, 0.82).

Interestingly, the GLP-1 and DPP-4 curves started diverging within the first 30 days of the index prescription date, said Chiang.

Session moderator Ghadeer Dawwas, PhD, said in an interview that patients with type 2 diabetes are increasingly using GLP-1 agonists because of the cardiovascular benefits associated with the agents, which include lower risks for stroke and heart failure, but the antithrombotic benefits are still debated.

“The current study indicates that GLP-1 agonists may help lower the risk of VTE in patients with type 2 diabetes, irrespective of their baseline body weight,” said Dawwas, a pharmacoepidemiologist and assistant professor of medicine at Vanderbilt University Medical Center in Nashville, Tennessee. “However, given the current landscape of evidence and the existence of conflicting data on VTE risk, clinicians should proceed with caution and await further studies to validate these findings before making clinical decisions.”

This study was funded by the National Blood Clot Alliance and Conquer Cancer Foundation. Chiang and Dawwas had no disclosures.

SAN DIEGO — Incidentally discovered vertebral fractures are common on scans in the general population, while the absolute risk for multiple myeloma (MM) in those with such fractures is “quite modest,” according to findings in a Danish cohort of more than 9000 patients.

The findings suggest that evaluation for underlying MM — as recommended in some clinical guidelines — may be unwarranted in the absence of symptoms or other clinical findings leading to suspicion of underlying MM, Rasmus Rønnemoes, MD, reported during a poster session at the annual American Society of Hematology conference.

“Some guidelines say to evaluate patients with vertebral fractures, including measuring serum M-protein and free light chains, and others say to evaluate only if there is an indication — but without specifying what an indication is,” Rønnemoes, of the Danish Red Blood Cell Center, Copenhagen University Hospital — Rigshospitalet, Denmark, said in an interview. 

To assess the association between vertebral fractures and MM, he and his colleagues studied 9065 individuals from the Danish general population, aged 33-94 years (median, 62 years) who were part of the Copenhagen General Population Study and who had attended a health examination and underwent a CT scan as part of the study. Overall, 1574 (17.4%) had one or more incidentally discovered vertebral fracture on the CT scan, and of those, 875 (9.7%) had a grade 1 fracture as the highest grade and 699 (7.7%) had grade 2-3 fractures.

During a median prospective follow-up of 5.5 years after the scan, 13 were diagnosed with myeloma.

“We did find an increased relative risk of myeloma in these patients, which we thought was quite interesting, but the absolute risk was quite modest,” Rønnemoes said.

The absolute 5-year risk for MM was 0.07% and 0.10% in women and men without vertebral fractures, respectively, and the risk for those with fractures was 0.17% and 0.24% in women and men with grade 1 fractures, respectively, and 0.43% and 0.63% in women and men with grade 2-3 fractures, respectively.

A case-cohort study based on more than 56,000 individuals from the UK Biobank cohort who had undergone a dual-energy x-ray absorptiometry scan as part of that study validated the findings in the Danish population: At median follow-up of 4 years, 49 patients in the validation cohort were diagnosed with myeloma, and the absolute 5-year risk for myeloma was 0.06% and 0.12% in women and men with grade 1 fractures, respectively, and 0.14% and 0.26% in women and men with grade 2-3 fractures, respectively.

Given the apparently modest absolute risk for MM in patients with incidentally discovered fractures in the absence of strong indications or risk, treatment guidelines should consider the potential harms associated with additional work up and a monoclonal gammopathy of undetermined significance diagnosis, Rønnemoes said. 

Such a diagnosis can lead to psychological distress in individuals who may never develop malignant disease, he noted.

“We just hope to bring more value to the guidelines by identifying who should be evaluated,” he said, adding that additional study — perhaps looking more closely at whether only the more severe fractures should prompt additional evaluation — is warranted.

Rønnemoes reported no disclosures.

SAN DIEGO — A new study linked longer duration and deeper intensity of tobacco smoking to more genetic mutations in myelodysplastic syndromes (MDSs), a group of bone marrow cancers that are similar to acute myeloid leukemia.

The prospective National MDS Natural History Study evaluated 1898 patients with recently diagnosed or suspected MDS. An adjusted analysis linked higher number of pack-years to more mutations (P = .006), with those at the 90th percentile with 3.5 times the number of mutations as nonsmokers, researchers reported at the American Society of Hematology (ASH) 2024 Annual Meeting.

The findings “suggest that smoking potentially contributes to the multistep molecular genetic pathogenesis that ultimately results in diagnosis of the cancer,” said corresponding author Mikkael A. Sekeres, MD, of the Sylvester Comprehensive Cancer Center, University of Miami Health System in Florida, at a news briefing. “The more you smoke, the more likely you are to acquire more mutations and even develop a higher risk of myelodysplastic syndromes. [More smoking] was also associated with progression and survival.”

While numbers are uncertain, an estimated 10,000 or more people in the United States each year are diagnosed with MDS, also known as preleukemia, according to the American Cancer Society. Median survival ranges from 1 to 10.6 years based on risk group, although the cancer society says the statistics are dated and mainly from Europe.

Multiple studies have linked smoking to MDS. The new study aims to understand the possible effects of smoking on genetic mutations.

The research analyzed 1898 patients enrolled from 2016 to 2023 (52% who had ever smoked; 18% current smokers; mean smoking years, 29.8 ± 16.9 years). The patients had diagnoses of MDSs, MDS/myeloproliferative neoplasm overlap, or precursor conditions such as clonal cytopenia of undetermined significance (CCUS).

Smokers were more likely than nonsmokers to be men (68% vs 54%; P < .001) and aged 70-79 years (45% vs 34%; P < .001).

After adjustment for confounders, smokers had more average mutations linked to MDS than nonsmokers (2.0 vs 1.4; P = .04). Those at the 75th percentile of pack-years had 1.8 times as many MDS-linked mutations as nonsmokers.

The 5-year cumulative incidence of disease progression was higher in long-term smokers than in nonsmokers and those with shorter smoking history (mean proportion progressed, 20+ years vs < 20 years smoking/nonsmoking, 27% [19%-36%] vs 18% [13%-24%]; P < .05, respectively).

Also, overall survival was lower in smokers than in nonsmokers for patients with CCUS (hazard ratio [HR], 1.91; 95% CI, 1.03-3.55; P = .04) but not for those with MDS (HR, 1.21; 95% CI, 0.53-1.30; P = .41).

“The data suggests that a patient with a new diagnosis of MDS who also smokes should be counseled to stop smoking,” Sekeres said.

This may seem counterintuitive to patients, he acknowledged. When Sekeres was a medical student, he counseled a female patient with advanced lung cancer to quit smoking. “The patient looked at me like I had three heads and she said: ‘Why should I stop smoking? The cats are already out of the bag. I have lung cancer.’ ”

But the new study points to a possible benefit from quitting smoking while sick. “It appears that smoking contributes to the acquisition of new genetic mutations that can lead to worsening of the myelodysplastic syndromes and even evolution of the cancer into acute myeloid leukemia,” Sekeres said.

He added: “One thing to understand about these cancers of the bone marrow is they can take years or decades to develop. They’re not one-hit wonders. Smoking caused very specific genetic mutations. The cool part of this is that they’re the same genetic mutations smoking has been shown to cause in cancers like lung cancer, so we’re seeing consistency across cancers.”

Sekeres said he himself will counsel patients with MDS or acute myeloid leukemia to stop smoking. “If there’s anything we can do to intervene to prevent myelodysplastic syndrome from evolving into acute leukemia, my word, I sure I’m going to try it.”

In an interview, Peter Greenberg, MD, professor of medicine at Stanford Cancer Center in California, who’s familiar with the study but didn’t take part in the research, said the study suggests that smoking in MDS isn’t just related to exposure to fumes “but appears to be a much more widespread problem” related to its impact on generating hematologic stem cell mutations.

Most clinicians don’t warn patients with MDS about the dangers of smoking because they’re not aware of tobacco’s connection to the disease, Greenberg said. But there’s another reason to bring up smoking, he said: It boosts the risk for cardiovascular disease, which may be partially responsible for decreased survival in smokers.

Sekeres disclosed ties with Kurome, Schrödinger, and Bristol-Myers Squibb. Other authors reported multiple and various relationships with industry. Greenberg had no disclosures.

SAN DIEGO — A new study linked longer duration and deeper intensity of tobacco smoking to more genetic mutations in myelodysplastic syndromes (MDSs), a group of bone marrow cancers that are similar to acute myeloid leukemia.

The prospective National MDS Natural History Study evaluated 1898 patients with recently diagnosed or suspected MDS. An adjusted analysis linked higher number of pack-years to more mutations (P = .006), with those at the 90th percentile with 3.5 times the number of mutations as nonsmokers, researchers reported at the American Society of Hematology (ASH) 2024 Annual Meeting.

The findings “suggest that smoking potentially contributes to the multistep molecular genetic pathogenesis that ultimately results in diagnosis of the cancer,” said corresponding author Mikkael A. Sekeres, MD, of the Sylvester Comprehensive Cancer Center, University of Miami Health System in Florida, at a news briefing. “The more you smoke, the more likely you are to acquire more mutations and even develop a higher risk of myelodysplastic syndromes. [More smoking] was also associated with progression and survival.”

While numbers are uncertain, an estimated 10,000 or more people in the United States each year are diagnosed with MDS, also known as preleukemia, according to the American Cancer Society. Median survival ranges from 1 to 10.6 years based on risk group, although the cancer society says the statistics are dated and mainly from Europe.

Multiple studies have linked smoking to MDS. The new study aims to understand the possible effects of smoking on genetic mutations.

The research analyzed 1898 patients enrolled from 2016 to 2023 (52% who had ever smoked; 18% current smokers; mean smoking years, 29.8 ± 16.9 years). The patients had diagnoses of MDSs, MDS/myeloproliferative neoplasm overlap, or precursor conditions such as clonal cytopenia of undetermined significance (CCUS).

Smokers were more likely than nonsmokers to be men (68% vs 54%; P < .001) and aged 70-79 years (45% vs 34%; P < .001).

After adjustment for confounders, smokers had more average mutations linked to MDS than nonsmokers (2.0 vs 1.4; P = .04). Those at the 75th percentile of pack-years had 1.8 times as many MDS-linked mutations as nonsmokers.

The 5-year cumulative incidence of disease progression was higher in long-term smokers than in nonsmokers and those with shorter smoking history (mean proportion progressed, 20+ years vs < 20 years smoking/nonsmoking, 27% [19%-36%] vs 18% [13%-24%]; P < .05, respectively).

Also, overall survival was lower in smokers than in nonsmokers for patients with CCUS (hazard ratio [HR], 1.91; 95% CI, 1.03-3.55; P = .04) but not for those with MDS (HR, 1.21; 95% CI, 0.53-1.30; P = .41).

“The data suggests that a patient with a new diagnosis of MDS who also smokes should be counseled to stop smoking,” Sekeres said.

This may seem counterintuitive to patients, he acknowledged. When Sekeres was a medical student, he counseled a female patient with advanced lung cancer to quit smoking. “The patient looked at me like I had three heads and she said: ‘Why should I stop smoking? The cats are already out of the bag. I have lung cancer.’ ”

But the new study points to a possible benefit from quitting smoking while sick. “It appears that smoking contributes to the acquisition of new genetic mutations that can lead to worsening of the myelodysplastic syndromes and even evolution of the cancer into acute myeloid leukemia,” Sekeres said.

He added: “One thing to understand about these cancers of the bone marrow is they can take years or decades to develop. They’re not one-hit wonders. Smoking caused very specific genetic mutations. The cool part of this is that they’re the same genetic mutations smoking has been shown to cause in cancers like lung cancer, so we’re seeing consistency across cancers.”

SAN DIEGO — Significant complications were common in female patients with sickle cell disease (SCD) who underwent fertility preservation (FP) procedures, and 13% required multiple retrieval cycles, a five-center retrospective study found.

Of 46 patients with SCD, complications occurred in 25 of 55 controlled ovarian hyperstimulation cycles, including 29 vaso-occlusive episodes (VOEs), researchers reported at the American Society of Hematology (ASH) 2024 Annual Meeting.

Of 21 post-retrieval VOEs, 19 required emergency department care or hospitalization.

“Baseline sickle cell disease severity is most likely associated with a patient’s risk of complications from an egg retrieval cycle,” study co-author Sarah Cromack, MD, a reproductive endocrinology and infertility fellow at Northwestern University, Chicago, said in an interview.

“Both hematologists and reproductive endocrinologists can use this information to plan ahead and anticipate possible issues, check blood counts prior to and after egg retrieval to see if transfusion is needed, and plan close follow-up during stimulation and immediately after egg retrieval to evaluate and treat pain.”

 

SCD Accelerates Decline in Ovarian Reserve

Pediatric hematologist Lydia H. Pecker, MD, MS, of Johns Hopkins University School of Medicine, Baltimore, the study’s corresponding author, said in an interview that SCD is “a disease of accelerated aging” that leads to accelerated decline in ovarian reserve. “The common indication for fertility preservation in SCD is before bone marrow transplant or gene therapy,” she said, although FP can also be offered to other patients with SCD.

According to Cromack, researchers launched the study to expand information about SCD and FP in light of sparse data about outcomes.

All the 46 patients had hemoglobin SS (HbSS, 93%) and HbSβ0-thalassemia (7%) and a median age of 23.7 (18-28) years. Almost all (44 patients) underwent FP prior to curative treatments, and all had at least one SCD-related complication, mainly cerebrovascular disease (16), acute chest syndrome (23), and more than two VOEs per year (31).

Median anti-Mullerian hormone (AMH) level (2.1 ng/mL), a measurement of ovarian reserve, was lower than the expected level of 2.8-3.4 ng/mL among women in the age range of the patients, the researchers reported. “This is consistent with previous studies showing lower AMH for age in women with sickle cell disease,” Pecker said.

 

Complications in 45% of Retrieval Cycles

“In terms of success of oocyte cryopreservation, the median number of mature eggs frozen was 11,” said co-author and reproductive endocrinologist Jessica Walter, MD, of Northwestern University, in an interview. “Given the average age of 24 years in the cohort, this would give each patient about a 70% estimated probability of at least one live birth from their cohort of frozen eggs. Thus, patients hoping for more than one child may want to consider more than one cycle of egg freezing.”

The rate of complications was “fairly high” at 45% of all cycles, Walter said. “These were mostly complications from underlying sickle cell disease, including unplanned transfusions and admissions for vaso-occlusive crises. Surprisingly, there were very few cases of ovarian hyperstimulation syndrome in this young patient group, which may be due to a combination of underlying vascular disease, lower peak estradiol levels, and slightly less eggs retrieved then would be expected compared to an age-matched healthy controls.”

Any FP complication was associated with more than three VOEs in the year before controlled ovarian hyperstimulation (mean of three VOEs per patient without complications vs six per patient with complications; P = .036).

 

Higher Than Normal Need for Multiple Cycles

Reproductive endocrinologist H. Irene Su, MD, professor and co-director of the Center for OB/GYN Research Innovations at Moores Cancer Center, University of California San Diego, praised the study as “an important report” in an interview.

Su, who wasn’t involved in the research, said the percentage of patients requiring more than one cycle due to cancellation or low oocyte yield — 13% — is “higher than expected, given the young age of this cohort.”

This could reflect the hypothesis that “sickle cell crises and hypoxia adversely affect the finite number of oocytes in the ovary,” she said.

As for the study findings regarding complications, she said the rate “is very high compared to the general infertility or fertility preservation population. It would be good to learn predictors of these outcomes so that fertility and hematology clinicians can work together to stratify risk and supportive services around FP cycles. It would also be good to know if the post-retrieval VOE were unexpected given the patient’s disease activity prior to FP.”

 

Message: FP in SCD Is Feasible, Acceptable

A.D. Mishkin, MD, MPH, associate professor of psychiatry and liaison to the Blood and Marrow Transplantation Program at NewYork–Presbyterian/Columbia University Irving Medical Center, New York City, said in an interview that the study “establishes the feasibility and acceptability of oocyte harvest and preservation in a population of patients with active ongoing symptoms from SCD. It also indicates their interest in pursuing fertility preservation in the setting of frequent crises and the potential for management of ensuing complications.”

Mishkin, who didn’t take part in the research, highlighted the finding that half the patients got access to FP via public insurance or research funding. “Even in this population where most women had multiple complications in the year prior to FP, and even among patients who needed multiple retrievals, these patients wanted to go through that risk to preserve their fertility,” Mishkin said. “This is an important finding given the very limited access many individuals have to FP due to its high cost and limited insurance coverage, which is also largely state-dependent.”

There’s another factor to consider regarding SCD and FP: The potential danger of pregnancy.

Corresponding author Pecker noted that “pregnancy is high risk for people with sickle cell disease. There are very high rates of severe maternal mortality and morbidity even in high-income countries. However, some of this is modifiable with routine use of chronic transfusions during pregnancy and with high-quality and integrated expert SCD and expert maternal fetal medicine care during pregnancy.”

The National Institutes of Health supported the research. Pecker reported receiving research funding from Alexion, Novartis, and Aummune and consulting for Novo Nordisk. Other authors reported no disclosures. Su and Mishkin reported no disclosures.

For younger, fit patients with mantle cell lymphoma (MCL), adding the Bruton tyrosine kinase (BTK) inhibitor acalabrutinib to standard induction therapy with bendamustine/rituximab followed by cytarabine/rituximab adds toxicity without improving efficacy, results of the phase 2 ECOG-ACRIN EA4181 trial indicate.

However, treating patients with bendamustine/rituximab plus acalabrutinib might be preferred to either option with cytarabine.

Although the results showed that the bendamustine/rituximab plus acalabrutinib regimen was not superior to standard induction therapy with or without acalabrutinib, it was the least toxic option. 

Standard induction therapy can be still be considered the standard for this patient population, but eliminating cytarabine represents “an appealing option to avoid high-dose cytarabine,” said study investigator Nina Wagner-Johnston, MD, from Sidney Kimmel Comprehensive Cancer Center, Johns Hopkins Hospital, Baltimore, Maryland, during a presentation of the findings at the American Society of Hematology 2024 annual meeting. 

The bendamustine/rituximab plus acalabrutinib regimen, where acalabrutinib replaced high-dose cytarabine, is “the most intriguing arm of the study,” Marcus Messmer, MD, with the Department of Hematology/Oncology, Fox Chase Cancer Center, Philadelphia, Pennsylvania, said in an interview. 

“The results suggest that bendamustine/rituximab plus acalabrutinib may be equivalent in efficacy to [standard induction] with less toxicity,” said Messmer, who was not involved in the study. 

Unfortunately, the study was not designed to show noninferiority of bendamustine/rituximab plus acalabrutinib compared to standard induction therapy, and the bendamustine/rituximab plus acalabrutinib arm was stopped early because of a lack of a superiority signal, Messmer added.

 

Inside the Findings

MCL is a rare and aggressive B-cell lymphoma that poses unique treatment challenges, particularly in younger patients, for whom the treatment “landscape is shifting rapidly,” Wagner-Johnston explained.

Wagner-Johnston noted that the optimal induction regimen for fit, younger patients with MCL is unclear, although the mainstay of treatment is intensive chemoimmunotherapy with cytarabine.

The standard bendamustine/rituximab followed by cytarabine/rituximab induction regimen is associated with high complete remission and undetectable measurable residual disease, with evidence of improved progression-free survival, she noted. 

“And we know that BTK inhibitors, in combination with chemoimmunotherapy, are highly effective in MCL and that achieving molecular remission or undetectable measurable residual disease is an independent predictor of long-term outcomes in patients. All of these features were key when designing ECOG-ACRIN EA 4181,” Wagner-Johnston told attendees. 

The study enrolled 369 patients, 18-70 years old, with untreated MCL, ECOG performance score 0-2, and adequate organ and marrow function. Study participants were randomized 1:1:1 to the standard induction control arm or to one of two experimental arms. These included the control arm of induction therapy with three cycles of bendamustine/rituximab followed by three cycles of cytarabine/rituximab, the standard induction plus acalabrutinib across both cycles, or six cycles of bendamustine/rituximab with acalabrutinib.

In the standard induction plus acalabrutinib arm, acalabrutinib was dosed continuously at 100 mg twice daily during the initial cycles, and during weeks 1 and 3 of the latter cycles.

The primary analysis focused on 260 patients with an end-of-treatment sample sent for measurable residual disease testing. Roughly 90% of patients completed study treatment, with no differences between treatment arms. 

The primary outcome was a composite of PET/CT complete molecular remission and peripheral blood undetectable measurable residual disease. In the control arm, 82% of patients achieved the primary outcome, as did 82% of patients in the standard induction plus acalabrutinib arm and 78% in the bendamustine/rituximab plus acalabrutinib arm. 

“Notably, neither of the experimental arms were superior to the standard-of-care arm across the board,” Wagner-Johnston said. Overall response rates were “quite high,” with complete response rates of more than 90%, with no differences between the arms. 

Similarly, no significant difference was seen in progression-free survival or overall survival between treatment arms. At a medium follow up of roughly 28 months, the 12-month progression-free survival rate was 90%-92% across the three groups.

The team also evaluated progression-free survival by measurable residual disease status, regardless of whether patients completed protocol therapy. “Not surprisingly,” said Wagner-Johnston, progression-free survival was superior for those with undetectable measurable residual disease, compared with those with detectable levels — but again there was no differences between treatment arms. 

Grades 3-5 treatment-related adverse events occurred in at least 5% of patients and were mostly hematologic. 

The bendamustine/rituximab plus acalabrutinib was associated with significantly less hematologic toxicity, with a febrile neutropenia rate of 4.0% vs 8.9% in the standard induction arm and 9.3% in the standard induction plus acalabrutinib arm. 

Grades 3-5 treatment-related anemia rates were much lower in the bendamustine/rituximab plus acalabrutinib arm (3.0% vs 18.5% for standard induction and 24.8% for standard plus cytarabine). Similarly, the bendamustine/rituximab plus acalabrutinib arm had lower rates of treatment-related grade 3 or higher thrombocytopenia (6.0% vs 44.4% and 51.2%, respectively). 

Across all three treatment groups, rates of neurotoxicity, renal toxicity, bleeding/hemorrhage, and cardiac toxicity were low.

Treatment discontinuations due to adverse events were also low (7%) across the arms, with five treatment-related deaths reported. 

“Standard high-dose cytarabine requires inpatient administration and carries risk of neurologic and hematologic toxicity, making it particularly difficult to give in a community setting,” Marcus said in an interview. “This study, along with updated results from the TRIANGLE study, suggests that we are moving away from high-dose cytotoxic therapy and toward targeted therapy in frontline management of mantle cell lymphoma.”

The study was supported by the National Cancer Institute. Wagner-Johnston has received research founding from Genentech, Merck, and AstraZenecca and consults for Beigene. Marcus had no relevant disclosures.

For younger, fit patients with mantle cell lymphoma (MCL), adding the Bruton tyrosine kinase (BTK) inhibitor acalabrutinib to standard induction therapy with bendamustine/rituximab followed by cytarabine/rituximab adds toxicity without improving efficacy, results of the phase 2 ECOG-ACRIN EA4181 trial indicate.

However, treating patients with bendamustine/rituximab plus acalabrutinib might be preferred to either option with cytarabine.

Although the results showed that the bendamustine/rituximab plus acalabrutinib regimen was not superior to standard induction therapy with or without acalabrutinib, it was the least toxic option. 

Standard induction therapy can be still be considered the standard for this patient population, but eliminating cytarabine represents “an appealing option to avoid high-dose cytarabine,” said study investigator Nina Wagner-Johnston, MD, from Sidney Kimmel Comprehensive Cancer Center, Johns Hopkins Hospital, Baltimore, Maryland, during a presentation of the findings at the American Society of Hematology 2024 annual meeting. 

The bendamustine/rituximab plus acalabrutinib regimen, where acalabrutinib replaced high-dose cytarabine, is “the most intriguing arm of the study,” Marcus Messmer, MD, with the Department of Hematology/Oncology, Fox Chase Cancer Center, Philadelphia, Pennsylvania, said in an interview. 

“The results suggest that bendamustine/rituximab plus acalabrutinib may be equivalent in efficacy to [standard induction] with less toxicity,” said Messmer, who was not involved in the study. 

Unfortunately, the study was not designed to show noninferiority of bendamustine/rituximab plus acalabrutinib compared to standard induction therapy, and the bendamustine/rituximab plus acalabrutinib arm was stopped early because of a lack of a superiority signal, Messmer added.

 

Inside the Findings

MCL is a rare and aggressive B-cell lymphoma that poses unique treatment challenges, particularly in younger patients, for whom the treatment “landscape is shifting rapidly,” Wagner-Johnston explained.

Wagner-Johnston noted that the optimal induction regimen for fit, younger patients with MCL is unclear, although the mainstay of treatment is intensive chemoimmunotherapy with cytarabine.

The standard bendamustine/rituximab followed by cytarabine/rituximab induction regimen is associated with high complete remission and undetectable measurable residual disease, with evidence of improved progression-free survival, she noted. 

“And we know that BTK inhibitors, in combination with chemoimmunotherapy, are highly effective in MCL and that achieving molecular remission or undetectable measurable residual disease is an independent predictor of long-term outcomes in patients. All of these features were key when designing ECOG-ACRIN EA 4181,” Wagner-Johnston told attendees. 

The study enrolled 369 patients, 18-70 years old, with untreated MCL, ECOG performance score 0-2, and adequate organ and marrow function. Study participants were randomized 1:1:1 to the standard induction control arm or to one of two experimental arms. These included the control arm of induction therapy with three cycles of bendamustine/rituximab followed by three cycles of cytarabine/rituximab, the standard induction plus acalabrutinib across both cycles, or six cycles of bendamustine/rituximab with acalabrutinib.

In the standard induction plus acalabrutinib arm, acalabrutinib was dosed continuously at 100 mg twice daily during the initial cycles, and during weeks 1 and 3 of the latter cycles.

The primary analysis focused on 260 patients with an end-of-treatment sample sent for measurable residual disease testing. Roughly 90% of patients completed study treatment, with no differences between treatment arms. 

The primary outcome was a composite of PET/CT complete molecular remission and peripheral blood undetectable measurable residual disease. In the control arm, 82% of patients achieved the primary outcome, as did 82% of patients in the standard induction plus acalabrutinib arm and 78% in the bendamustine/rituximab plus acalabrutinib arm. 

“Notably, neither of the experimental arms were superior to the standard-of-care arm across the board,” Wagner-Johnston said. Overall response rates were “quite high,” with complete response rates of more than 90%, with no differences between the arms.

Patients with diffuse large B-cell lymphoma (DLBCL) continue to show superior progression-free survival at 5 years with first-line pola-R-CHP, compared with the R-CHOP regimen, according to updated results of the phase 3 POLARIX study.

These findings “confirm pola-R-CHP as the standard of care for patients with previously untreated intermediate- or high-risk DLBCL,” said lead investigator Gilles Salles, MD, PhD, who presented the extended results at the American Society of Hematology (ASH) 2024 Annual Meeting.

Pola-R-CHP is a modified version of the R-CHOP regimen (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) in which vincristine is replaced with polatuzumab vedotin. The modified regimen was approved by the Food and Drug Administration in April 2023 on the basis of 2-year results from the same study.

In POLARIX, researchers randomized 879 previously untreated adult patients with CD20-positive DLBCL (median age, 66 years) to six to eight 21-day cycles of treatment with either pola-R-CHP or R-CHOP. The primary endpoint was progression-free survival, and secondary endpoints included complete remission and overall survival.

The initial 2-year results — progression-free survival of 76.7% for pola-R-CHP vs 70.2% for R-CHOP — “were the first in 20 years” showing benefits for patients with DLBCL, said Salles, from Memorial Sloan Kettering Cancer Center, New York City.

In the current analysis, there were 879 patients in the global intention-to-treat population — 440 who received pola-R-CHP and 439 who received R-CHOP — and 873 in the safety analysis.

At the 5-year follow-up, Salles and colleagues observed a sustained and significant progression-free survival benefit in patients treated with pola-R-CHP, compared with those who received R-CHOP (64.9% vs 59.1%; hazard ratio [HR], 0.77).

Patients receiving the modified regimen also demonstrated significantly higher rates of complete remission at 5 years (71.8% vs 66.5%; HR, 0.75). These data tell us that for patients who reach complete remission at the end of treatment, the vast majority are still in remission at 5 years, said Salles.

For patients who did progress, those treated with pola-R-CHP had fewer subsequent therapies than those treated with R-CHOP. This included radiotherapy (9.5% vs 14.1%), systemic therapy (20.0% vs 28.2%), platinum-based therapy (9.8% vs 15.5%), stem cell transplant (5.0% vs 8.4%), chimeric antigen receptor T-cell therapy (2.3% vs 4.1%), and bispecifics (1.4% vs 2.1%).

The 5-year overall survival, a secondary endpoint, was numerically better but not significantly so among patients treated with pola-R-CHP (82.3% vs 79.5%; HR, 0.85).

In a competing risk analysis, the cumulative incidence of lymphoma-related deaths at 5 years was 9.1% with pola-R-CHP vs 12.2% with R-CHOP. The probability of non-lymphoma–related deaths, including death due to study treatment, was similar between the two groups at 5 years — 8.56% with pola-R-CHP vs 8.93% with R-CHOP.

An exploratory analysis of progression-free survival and overall survival in subgroups of the patient population, including those with high-risk disease, showed a trend in favor of pola-R-CHP in almost all cases, but Salles warned that the analysis was underpowered.

“I think that interpreting this data to decide the care of the patient should be done very cautiously,” he said.

The researchers did not observe any new safety signals, with pola-R-CHP continuing to show a favorable benefit-risk profile. Looking at adverse events of all grades, Salles noted slightly less peripheral neuropathy with pola-R-CHP (50.3% vs 52.4%), slightly more infection (47.9% vs 44.0%), as well as a favorable trend for pola-R-CHP regarding cardiac arrhythmia (3.6% vs 5.2%) and carcinogenicity (1.0% vs 2.4%), and “very slight and tiny differences” in neutropenia (48.5% vs 45.8%), anemia (33.3% vs 30.1%), and thrombocytopenia (18.0% vs 17.3%).

While the researchers concluded that the study findings confirm pola-R-CHP as the standard of care for patients with previously untreated intermediate- or high-risk DLBCL, Ajay Major, MD, had some reservations.

The results confirm “a small but significant benefit” in progression-free survival and no significant difference in overall survival, but there is some question as to whether pola-R-CHP is appropriate for all-comers with intermediate- or high-risk DLBCL, noted Major, a lymphoma specialist and assistant professor of medicine at the University of Colorado School of Medicine, Aurora, who was not involved in this analysis.

“The subgroup analysis in POLARIX for efficacy of pola-R-CHP based on cell of origin is not adequately powered, and further dedicated on this question studies are needed,” Major said in an interview.

One study presented at the meeting by Major’s group concluded that cell of origin is a strong predictor of the activity of pola-containing therapy in patients with relapsed/refractory large B-cell lymphoma, while another analysis of POLARIX showed progression-free survival and overall survival benefits of pola-R-CHP over R-CHOP in patients with the activated B-cell subtype of DLBCL but not those with the germinal center B-cell subtype, Major noted.

“I think many oncologists will extrapolate from these other data sources and preferentially use pola-R-CHP in patients with activated B-cell or non-germinal center DLBCL,” he predicted.

The study was funded by F. Hoffmann–La Roche/Genentech. Salles reported disclosures with the following companies: BeiGene (consultancy), AbbVie (consultancy, research funding), Genentech/Roche (consultancy, research funding), Incyte (consultancy), and BMS/Celgene (consultancy), among others. Major reported conflicts of interest with Roche/Genentech (consultancy), GSK (research funding), and Incyte (research funding).

One study presented at the meeting by Major’s group concluded that cell of origin is a strong predictor of the activity of pola-containing therapy in patients with relapsed/refractory large B-cell lymphoma, while another analysis of POLARIX showed progression-free survival and overall survival benefits of pola-R-CHP over R-CHOP in patients with the activated B-cell subtype of DLBCL but not those with the germinal center B-cell subtype, Major noted.

“I think many oncologists will extrapolate from these other data sources and preferentially use pola-R-CHP in patients with activated B-cell or non-germinal center DLBCL,” he predicted.

The study was funded by F. Hoffmann–La Roche/Genentech. Salles reported disclosures with the following companies: BeiGene (consultancy), AbbVie (consultancy, research funding), Genentech/Roche (consultancy, research funding), Incyte (consultancy), and BMS/Celgene (consultancy), among others. Major reported conflicts of interest with Roche/Genentech (consultancy), GSK (research funding), and Incyte (research funding).
