FDA investigates secondary cancers from CAR T-cell therapies
Secondary cancers are a known risk for this class of immunotherapies, known as B-cell maturation antigen (BCMA)–directed or CD19-directed autologous CAR T-cell therapies, and are included in the prescribing information for these drugs. However, the FDA has received 19 reports of secondary cancers, including CAR-positive lymphoma, since 2017, when the first CAR T-cell treatments were approved, according to Endpoints News.
Most of these reports came from the FDA’s postmarketing adverse event system and others from clinical trial data.
Although the overall benefits of these products continue to outweigh their potential risks, “FDA is investigating the identified risk of T-cell malignancy with serious outcomes, including hospitalization and death, and is evaluating the need for regulatory action,” the agency said in a press release.
Currently approved products in this class include idecabtagene vicleucel (Abecma), lisocabtagene maraleucel (Breyanzi), ciltacabtagene autoleucel (Carvykti), tisagenlecleucel (Kymriah), brexucabtagene autoleucel (Tecartus), and axicabtagene ciloleucel (Yescarta).
“Patients and clinical trial participants receiving treatment with these products should be monitored life-long for new malignancies,” the FDA added.
Suspected adverse events, including T-cell cancers, should be reported by contacting the FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.

FDA panel voices concerns over 2 lymphoma accelerated approvals
At a Nov. 16 meeting, the Oncologic Drugs Advisory Committee of the Food and Drug Administration reviewed the reasons for delays in confirmatory trials for pralatrexate (Folotyn) and belinostat (Beleodaq), both now owned by East Windsor, N.J.–based Acrotech. The FDA granted accelerated approval for pralatrexate in 2009 and belinostat in 2014.
“The consensus of the advisory committee is that we have significant concerns about the very prolonged delay and getting these confirmatory studies underway,” said Andy Chen, MD, PhD, of Oregon Health & Science University, Portland, who served as acting ODAC chair for the meeting.
Corporate ownership changes were among the reasons Acrotech cited for the long delays in producing the confirmatory research on pralatrexate and belinostat. Allos Therapeutics won the FDA approval of pralatrexate in 2009. In 2012, Spectrum Pharmaceuticals acquired Acrotech. Spectrum won approval of belinostat in 2014. Acrotech acquired Spectrum in 2019.
The FDA didn’t ask ODAC to take votes on any questions at the meeting. Instead, the FDA sought its expert feedback about how to address the prolonged delays with pralatrexate and belinostat research and, in general, how to promote more timely completion of confirmatory trials for drugs cleared by accelerated approval.
Pralatrexate and belinostat are both used to treat relapsed or refractory peripheral T-cell lymphoma, a rare and aggressive disease affecting about 10,000-15,000 people annually in the United States.
Through the accelerated approval process, the FDA seeks to speed medicines to people with fatal and serious conditions based on promising signs in clinical testing.
The initial pralatrexate and belinostat were based on phase 2, single-arm, monotherapy studies, with about 109 evaluable patients in the key pralatrexate study and 120 evaluable patients in the belinostat study. As is common, these phase 2 tests used measurements of cancer progression, known as the overall response rate.
The FDA then expects companies to show through more extensive testing that medicines cleared with accelerated approvals can deliver significant benefits, such as extending lives. When there are delays in confirmatory trials, patients can be exposed to medicines, often with significant side effects, that are unlikely to benefit them.
For example, the FDA granted an accelerated approval in 2011 for romidepsin for this use for peripheral T-cell lymphoma, the same condition for which pralatrexate and belinostat are used. But in 2021, Bristol-Myers Squibb withdrew the approval for that use of romidepsin when a confirmatory trial failed to meet the primary efficacy endpoint of progression free survival.
At the meeting, Richard Pazdur, MD, who leads oncology medicine at the FDA, urged Acrotech to shorten the time needed to determine whether its medicines deliver significant benefits to patients and thus merit full approval, or whether they too may fall short.
“We’re really in a situation where patients are caught in the middle here,” Dr. Pazdur said. “I feel very bad for that situation and very bad for the patients that they don’t have this information.”
‘Dangerous precedent’
The FDA in recent years has stepped up its efforts to get companies to complete their required studies on drugs cleared by accelerated approvals. The FDA has granted a total of 187 accelerated approvals for cancer drugs. Many of these cover new uses of established drugs and others serve to allow the introduction of new medicines.
For more than half of these cases, 96 of 187, the FDA already has learned that it made the right call in allowing early access to medicines. Companies have presented study results that confirmed the benefit of drugs and thus been able to convert accelerated approvals to traditional approvals.
But 27 of the 187 oncology accelerated approvals have been withdrawn. In these cases, subsequent research failed to establish the expected benefits of these cancer drugs.
And in 95 cases, the FDA and companies are still waiting for the results of studies to confirm the expected benefit of drugs granted accelerated approvals. The FDA classifies these as ongoing accelerated approvals. About 85% of these ongoing approvals were granted in the past 5 years, in contrast to 14 years for pralatrexate and 9 for belinostat.
“It sets a dangerous precedent for the other sponsors and drug companies to have such outliers from the same company,” said ODAC member Toni K. Choueiri, MD, of Harvard Medical School and the Dana-Farber Cancer Institute, both in Boston.
The current agreement between the FDA and Acrotech focuses on a phase 3 trial, SPI-BEL-301 as the confirmatory study. Acrotech’s plan is to start with dose optimization studies in part 1 of the trial, with part 2 meant to see if its medicines provide a significant benefit as measured by progression-free survival.
The plan is to compare treatments. One group of patients would get belinostat plus a common cancer regimen known as CHOP, another group would get pralatrexate plus the COP cancer regimen, which is CHOP without doxorubicin, and a third group would get CHOP.
Acrotech’s current time line is for part 1, which began in October, to finish by December 2025. Then the part 2 timeline would run from 2026 to 2030, with interim progression-free survival possible by 2028.
ODAC member Ashley Rosko, MD, a hematologist from Ohio State University, Columbus, asked Acrotech what steps it will take to try to speed recruitment for the study.
“We are going to implement many strategies,” including what’s called digital amplification, replied Ashish Anvekar, president of Acrotech. This will help identify patients and channel them toward participating clinical sites.
Alexander A. Vinks, PhD, PharmD, who served as a temporary member of ODAC for the Nov. 16 meeting, said many clinicians will not be excited about enrolling patients in this kind of large, traditionally designed study.
Dr. Vinks, who is professor emeritus at Cincinnati Children’s Hospital Medical Center and University of Cincinnati, now works with consultant group NDA, a firm that advises companies on developing drugs.
Dr. Vinks advised Acrotech should try “to pin down what is most likely a smaller study that could be simpler, but still give robust, informative data.”

T-cell cancers: CAR T therapy to the rescue?
As Baylor College of Medicine’s Max Mamonkin, PhD, noted in a presentation, patients with conditions such as T-cell lymphoma and T-cell acute lymphoblastic leukemia (ALL) have limited treatment options and grim prognoses. “This is an area with huge unmet need,” he said. “They don’t have options that patients with B-cell malignancies have, like [CAR T-cell therapy] and bispecifics.”
One big challenge is that CAR-targeted antigens in T-cell blood cancers are shared by both normal and malignant T-cells, he said. That poses a risk during therapy that the engineered cells will target each other with “disastrous consequences.”
Research by his team and others have shown that gene editing can help the cells to stop engaging in “fratricide,” Dr. Mamonkin said.
The problem is “it’s much easier to do gene editing on the bench and much harder to translate it into the clinic,” especially in light of limitations posed by the Food and Drug administration, he said. “We started to think about alternative methods to get this approach to the clinic.”
One strategy is to use pharmacologic inhibition via the Bruton’s tyrosine kinase inhibitors ibrutinib and dasatinib to mute the tendency of CAR T toward self-destruction. When tested in mice, “the unedited cells not just persisted, they expanded with sustained anti-leukemic activity and significantly prolonged their lives even more than the knock-out [gene-edited] cells.”
The research has now moved to human subjects. In 2021, researchers at Texas Children’s Hospital and Houston Methodist Hospital launched a clinical trial to test CD7 CAR T-cell therapy with CD28 in 21 patients with CD7-positive T-cell lymphoma. The initial part of the transplant-enabling CRIMSON-NE study is expected to be completed by mid-2024, and patients will be followed for 15 years.
Early results show that CD7 CAR T-cells have persisted in the blood of patients over weeks and months, Dr. Mamonkin said. In eight patients, “we’re seeing good evidence of activity,” with two patients reaching complete remissions.
The findings suggest that CD7 can be targeted in T-cell malignancies, he said. What about CD5? A similar study known as MAGENTA is testing CD5 CAR T-cell therapy with CD28 in T-cell leukemia and lymphoma in 42 patients. The phase 1 trial began in 2017. It’s expected to be completed by 2024 and to track patients for 15 years.
Results so far have been positive with complete remission achieved in three of nine patients with T-cell lymphoma; two remained in remission for more than 4 years.
Results in T-cell ALL improved after researchers adjusted the manufacturing of the cells. As for durability in these patients, “we try to bridge them to transplantation as soon as possible.”
As for side effects overall, there wasn’t much immune effector cell-associated neurotoxicity syndrome, and the CD7 approach seems to be more inflammatory, he said.
The presentation didn’t address the potential cost of the therapies. CAR T-cell therapy can cost between $500,000 and $1 million. Medicare covers it, but Medicaid may not depending on the state, and insurers may refuse to pay for it.
Dr. Mamonkin disclosed ties with Allogene, Amgen, Fate, Galapagos, March Bio, and NKILT.

FROM SITC 2023
PD-1 inhibitor improves outcomes in NHL subtype
, while pretreatment mutational profiles offer clues as to which patients may respond to such anti-PD-1 treatments, according to studies presented at the European Society of Medical Oncology (ESMO) Congress 2023.
“We found that toripalimab combined with radiotherapy is safe and has promising efficacy for stage I/II extranodal NK/T cell lymphoma [patients] who have poor response after previous standard chemotherapy,” said first author Ming Jiang, MD, of the department of medical oncology, Cancer Center, West China School of Medicine/West China Hospital of Sichuan University, Chengdu, China.
“This combined strategy can not only improve patient efficacy but also avoid unnecessary medication, and is worth further exploration,” she said in a presentation at ESMO on Oct. 27 in Madrid. The current standard of care for extranodal NK/T cell lymphoma, a subtype of non-Hodgkin lymphoma, is L-asparaginase or pegaspargase-based multi-agent chemotherapy combined with radiotherapy.
However, for patients who fail to respond to first-line treatment, the prognosis is poor: The median progression-free survival of those patients is approximately 4.5 months, with a median overall survival of about 6.4 months, Dr. Jiang explained.
“There is a need to establish a better first-line treatment for this group of patients,” she said.
In the prospective, single-arm, multicenter phase 2 study, Dr. Jiang and her colleagues enrolled patients with stage 1 and 2 extranodal NK/T cell lymphoma who had failed to achieve a complete response following 2-3 cycles of multi-agent chemotherapy.
Of the patients, eight (36.4%) had partial response, eight (36.2%) had stable disease, and six (27.2%) had progressive disease after the chemotherapy.
The patients were treated with toripalimab at 240 mg, once every 3 weeks, plus radiotherapy at a dose of 56 Gy, sequentially with or without two to four cycles of chemotherapy.
Patients who did not have disease progression were then continued with toripalimab for 1 year or until disease progression or intolerable toxicity.
The 22 patients had a median age of 45 (range 26-64) and 14 were male. Most were stage 1 (77.3%; 17) and the remaining were stage 2, while 81% had primary tumor invasion.
For the primary endpoint, at 3 months following radiotherapy, the overall response rate was 90.9%, with 17 patients (77.3%) having a complete response, 3 (13.6%) a partial response, and 2 (9.1%) having progressive disease.
Eight who had responded to previous chemotherapy received two additional chemotherapy cycles after completion of radiotherapy, while the others were treated with toripalimab alone.
With a median follow-up of 23 months (range 3-78), the 2-year progression-free survival was 81.6%, and overall survival was 95.0%.
Two of three patients with a partial response had a recurrence after radiotherapy at 5 and 10 months; one of the complete-response patients had a recurrence at 60 months, and two patients with progressive disease died at 9 months after radiotherapy.
In terms of safety, the most common adverse events during and after radiotherapy included oral mucositis and hypothyroidism. No adverse events of grade 3 or higher were reported.
Dr. Jiang speculated that “radiotherapy could synergize PD-1 inhibitors,” and she urged that “optimal radiotherapy and PD-1 inhibitor administration plans should be further explored.”
Genetic factors
Additional research presented in that ESMO session offered insights into the genetic factors that may play key roles in either response or resistance to anti-PD-1 therapy in peripheral T cell lymphoma (PTCL), of which extranodal NK/T cell lymphoma is a subtype.
The findings are from a genetic analysis of a phase 2 trial that demonstrated benefits the PD-1 inhibitor geptanolimab in patients with PTCL who failed initial chemotherapy.
Specifically, geptanolimab treatment was associated with an objective response rate of 40.4%, a complete response rate of 14.6%, and partial response rate of 25.8%.
Of 44 patients who had been treated with geptanolimab and had next-generation sequencing genetic data available, PD-L1 expression was found to be significantly elevated among those who had a complete or partial response, whereas PD-L1 expression was lower among those who had disease progression, which is consistent with previous research suggesting that low PD-L1 expression is linked to poorer response to anti-PD-1 therapies.
Tumor mutation burden did not exhibit significant prognostic value. However, the authors noted that this may be confounded by variation across PTCL subtypes.
Among other key findings were that JAK3 and EZH2 mutations, which are among the top genes frequently mutated in PTCL and extranodal NK/T cell lymphoma, were consistently associated with low PD-L1 expression (P < .05) and shorter progression-free survival (HR 5.97; P = .027, JAK3, and HR 4.76; P = .027 EZH2).
“Notably, we found JAK3 mutations, which are vital and prevalent in PTCL, reduced PD-L1 levels in vivo and in vitro, which are of great clinical and biological sense,” said the study’s first author, Ning Lou, MD, of the Cancer Hospital Chinese Academy of Medical Sciences & Peking Union Medical College, in Beijing.
Commenting on the study, discussant Olivier Casasnovas, MD, PhD, of the department of hematology, University Hospital Francois Mitterrand in Dijon, France, said that the findings are especially notable in relation to extranodal NK/T cell lymphoma.
“The clinical relevance of anti PD1 is mainly observed in relapsing/recurrent extranodal NK/T cell lymphoma, and much less in other T-cell lymphoma subtypes,” he told this news organization.
“So identifying molecular events associated with the chance of response to a PD1 blocker in relapsing extranodal NK/T cell lymphoma is important as PD1-blockers are recommended to treat [those] patients,” Dr. Casasnovas added.
Furthermore, “the interest of next-generation sequencing to identify JAK3 mutations associated with low level of PDL1 expression and weak response to anti PD1 blockers is important as JAK3 mutated tumors are potentially targetable by JAK inhibitors such as tofacitinib,” he said.
“Obviously this assumption has to be tested in clinical trials but it’s an interesting lead.”
The research on toripalimab additionally shows that “the combination of radiotherapy and PD1 blockers provides a high response rate in patients who are nonresponders to asparaginase-based chemotherapy on the basis of PET evaluation and could be a new option for optimizing the first line treatment of extranodal NK/T cell lymphoma patients,” Dr. Casasnovas added.
The authors and Dr. Casasnovas had no disclosures to report.
, while pretreatment mutational profiles offer clues as to which patients may respond to such anti-PD-1 treatments, according to studies presented at the European Society of Medical Oncology (ESMO) Congress 2023.
“We found that toripalimab combined with radiotherapy is safe and has promising efficacy for stage I/II extranodal NK/T cell lymphoma [patients] who have poor response after previous standard chemotherapy,” said first author Ming Jiang, MD, of the department of medical oncology, Cancer Center, West China School of Medicine/West China Hospital of Sichuan University, Chengdu, China.
“This combined strategy can not only improve patient efficacy but also avoid unnecessary medication, and is worth further exploration,” she said in a presentation at ESMO on Oct. 27 in Madrid. The current standard of care for extranodal NK/T cell lymphoma, a subtype of non-Hodgkin lymphoma, is L-asparaginase or pegaspargase-based multi-agent chemotherapy combined with radiotherapy.
However, for patients who fail to respond to first-line treatment, the prognosis is poor: The median progression-free survival of those patients is approximately 4.5 months, with a median overall survival of about 6.4 months, Dr. Jiang explained.
“There is a need to establish a better first-line treatment for this group of patients,” she said.

Rare lymphomas: Desperately seeking new txs
“Over the past 5 years, researchers have gotten a clearer picture of the different subtypes of peripheral T-cell lymphomas, and with this knowledge we are trying to identify potential targets of new treatments. Despite some progress, the need for these new treatments is still acute, due to the disease’s many subtypes and the difficulty of enrolling sufficient numbers of patients in clinical trials,” said Julie M. Vose, MD, MBA, of the University of Nebraska Medical Center, Omaha, speaking at the Lymphoma, Leukemia and Myeloma Congress 2023, in New York. Before her presentation at this year’s conference, Dr. Vose was awarded the SASS-ARENA Foundation’s John Ultmann Award for Major Contributions to Lymphoma Research.
Dr. Vose noted that only one subtype of PTCL, ALK+ ALCL, responds well to frontline treatment with CHOP (cyclophosphamide, doxorubicin, vincristine, prednisolone). Patients with the ALK+ ALCL signature treated with CHOP have a 5-year overall survival (OS) rate of 70%-90%, but this group only makes up about 6% of PTCL cases in North America, she added.
One of the most promising breakthroughs in treatment has been the addition of the anti-CD30 antibody-drug conjugate brentuximab vedotin (BV) to chemotherapy with CHP (cyclophosphamide, doxorubicin, prednisone), Dr. Vose said. Results from the ECHELON-2 trial indicate that CD30+ PTCL patients have improved performance with R-CHP, compared with CHOP; 5-year progression free survival (PFS) rates were 51.4% with R+CHP versus 43.0% with CHOP, and 5-year overall survival rates were 70.1% versus 61.0%, respectively.
“ALCL is one of the most prevalent PTCL subtypes and accounts for about 24% of all PTCL; the current standard-of-care for induction treatment in these patients is BV-CHP,” said Jia Ruan, MD, PhD, of Weill Cornell Medicine in New York. Dr. Ruan explained the limitation of adding BV-CHP, saying “We don’t have as effective biological targeted therapies in other subtypes of T-cell lymphoma, such as PTCL NOS [not-other specified] or angioimmunoblastic T-cell lymphoma.”
There is evidence that autologous stem cell transplant (ACST) can increase PFS and OS in newly diagnosed patients with angioimmunoblastic T-cell lymphoma (AITL), but not in patients with other types of newly diagnosed PTCL. The estimated 2-year OS and PFS for patients with AITL who received ASCT + chemotherapy were 93.3% and 68.8 respectively versus 52.9% and 41.2 in the non-ASCT group. This news is promising, yet Dr. Vose presented statistics indicating that AITL PTCL has been estimated to account for less than 19% of PTCL cases.
Despite the improvements in PFS and OS in a few subtypes for frontline PTCL, 60% of patients with non-ALCL PTCL will relapse, and relapsed/ refractory (R/R) PTCL patients have a median PFS of 9.6 months. Several studies have shown some promise for improving outcomes in R/R PTCL patients, such as the phase-II PRIMO study of duvelisib (a dual PI3K-delta,gamma inhibitor), in which there was an overall response rate of 50% and a complete response rate of 32%. Despite these modest gains, the prognosis for most PTCL patients remains poor. Dr. Vose concluded her presentation by reiterating the need for new agents and for further research. She emphasized that studies will need to be collaborative and international to enroll sufficient patients.
Dr Ruan drew a similar conclusion, noting “We need to increase clinical, translational and basic research on a collaborative scale, so that we can advance bench-to-bedside discovery and bring new treatment to patients quickly.”
Dr. Vose disclosed research funding from Epizyme, GenMab, Kite, Novartis, and Lilly. Dr. Ruan disclosed clinical research trial support from BMS and Daiichi Sankyo.

AT LLM CONGRESS 2023
Antibody shows promise in preventing GVHD
Early, intriguing research suggests that preventing acute graft-versus-host disease (GVHD) in the gut – a potentially life-threatening complication of allogeneic hematopoietic cell transplantation (allo-HCT) – could be accomplished by the administration of a single antibody that targets the anti-DLL4 Notch signaling pathway, without compromising the stem cell transplant.
“The major surprise was that none of the anti–DLL4-treated animals developed acute gastrointestinal GVHD for the entire duration of the study. This was a remarkable finding, given that intestinal GVHD is otherwise seen in the vast majority of nonhuman primate transplant recipients that receive either no prophylaxis, or prophylaxis with agents other than anti-DLL4 antibodies,” co–senior author Ivan Maillard, MD, PhD, a professor of medicine and vice chief for research in hematology-oncology at the University of Pennsylvania, Philadelphia, said in an interview.
“The timing was critical,” the authors noted in the study, recently published in Science Translational Medicine. “Intervening before any symptoms of GvHD appear made the long-term protection possible.”
While GVHD may be mild to moderate in chronic forms, acute cases can be serious, if not fatal, and nearly all severe acute GVHD prominently involves the gastrointestinal tract, which can drive activation of pathogenic T cells and potentially lead to tissue damage following allo-HCT.
Systemic corticosteroids are standard first-line treatment for acute GVHD. However, response rates generally range only from 40% to 60%, and there are concerns of side effects. Meanwhile, second-line treatments are of inconsistent benefit.
With previous studies on mice showing benefits of targeting Notch pathway inhibition, particularly DLL4, Dr. Maillard and colleagues further investigated the effects in nonhuman primates that were allo-HCT recipients, using the anti-DLL4 antibody REGN421, which has pharmacokinetic and toxicity information available from previous studies.
The nonhuman primates were treated with one of two dosing regimens: a single dose of REGN421 3 mg/kg at baseline, post HCT, (n = 7) or three weekly doses at days 0, 7 and 14, post transplant (n = 4). Those primates were compared with 11 primates receiving allo-HCT transplants that received supportive care only.
Primates receiving three weekly doses of REGN421 showed antibody concentrations of greater than 2 mcg/mL for more than 30 days post HCT. A single dose of REGN421 was associated with protection from acute GVHD at day 0, while three weekly doses showed protection at day 0, 7, and 14, consistent with an impact of REGN421 during the early phases of T-cell activation.
Compared with animals receiving only supportive care, prophylaxis with REGN421 was associated with delayed acute GVHD onset and lengthened survival.
Of the 11 primates treated with REGN421, none developed clinical signs of gastrointestinal acute GVHD, whereas the majority of those receiving standard care or other preventive interventions did.
“Detailed analysis of acute GVHD clinical presentations in REGN421-treated animals in comparison to no treatment controls revealed near complete protection from GI-acute GvHD with REGN421,” the authors reported.
Furthermore, pathology scores in the gastrointestinal tract were lower with REGN421 treatment, compared with the no-treatment cohort, and the scores matched those of healthy nontransplanted nonhuman primates.
The primates treated with REGN421 did ultimately develop other clinical and pathologic signs of skin, hepatic or pulmonary acute GVHD, but without gastrointestinal disease.
The treatment was not associated with any adverse effects on the allo-HCT, with primates receiving either a single dose or three weekly doses of REGN421 showing rapid donor engraftment after allo-HCT, including high bone marrow, whole blood, and T-cell donor chimerism.
“Reassuringly, short-term systemic DLL4 blockade with REGN421 did not trigger unexpected side effects in our nonhuman primate model, while preserving rapid engraftment as well hematopoietic and immune reconstitution.”
The mechanism preserving the engraftment, described as a “major surprise,” specifically involved DLL4 inhibition blocking the homing of pathogenic T cells to the gut while preserving homing of regulatory T cells that dampen the immune response, Dr. Maillard explained.
“This effect turned out to be at least in part through a posttranslational effect of DLL4/Notch blockade on integrin pairing at the T-cell surface,” he explained. “This was a novel and quite unexpected mechanism of action conserved from mice to nonhuman primates.”
The results are encouraging in terms of translating to humans because of their closer similarities in various physiological factors, Dr. Maillard said.
“The nonhuman primate model of transplantation [offers] a transplantation model very close to what is being performed in humans, as well as the opportunity to study an immune system very similar to that of humans in nonhuman primates,” he said.
Dr. Maillard noted that, while trials in humans are not underway yet, “we are in active discussions about it,” and the team is indeed interested in testing REGN421 itself, with the effects likely to be as a prophylactic strategy.
There are currently no approved anti-DLL4 antibody drugs for use in humans.
“Our approach is mostly promising as a preventive treatment, rather than as a secondary treatment for GVHD, because DLL4/Notch blockade seems most active when applied early after transplantation during the time of initial seeding of the gut by T cells (in mice, we had observed the critical time window for a successful intervention to be within 48 hours of transplantation),” Dr. Maillard said.“There remain questions about which other prophylactic treatments we should ideally combine anti-DLL4 antibodies with.”

Early, intriguing research suggests that preventing acute graft-versus-host disease (GVHD) in the gut – a potentially life-threatening complication of allogeneic hematopoietic cell transplantation (allo-HCT) – could be accomplished by the administration of a single antibody that targets the anti-DLL4 Notch signaling pathway, without compromising the stem cell transplant.
“The major surprise was that none of the anti–DLL4-treated animals developed acute gastrointestinal GVHD for the entire duration of the study. This was a remarkable finding, given that intestinal GVHD is otherwise seen in the vast majority of nonhuman primate transplant recipients that receive either no prophylaxis, or prophylaxis with agents other than anti-DLL4 antibodies,” co–senior author Ivan Maillard, MD, PhD, a professor of medicine and vice chief for research in hematology-oncology at the University of Pennsylvania, Philadelphia, said in an interview.
“The timing was critical,” the authors noted in the study, recently published in Science Translational Medicine. “Intervening before any symptoms of GvHD appear made the long-term protection possible.”
While GVHD may be mild to moderate in chronic forms, acute cases can be serious, if not fatal, and nearly all severe acute GVHD prominently involves the gastrointestinal tract, which can drive activation of pathogenic T cells and potentially lead to tissue damage following allo-HCT.
Systemic corticosteroids are standard first-line treatment for acute GVHD. However, response rates generally range only from 40% to 60%, and there are concerns of side effects. Meanwhile, second-line treatments are of inconsistent benefit.
With previous studies on mice showing benefits of targeting Notch pathway inhibition, particularly DLL4, Dr. Maillard and colleagues further investigated the effects in nonhuman primates that were allo-HCT recipients, using the anti-DLL4 antibody REGN421, which has pharmacokinetic and toxicity information available from previous studies.
The nonhuman primates were treated with one of two dosing regimens: a single dose of REGN421 3 mg/kg at baseline, post HCT, (n = 7) or three weekly doses at days 0, 7 and 14, post transplant (n = 4). Those primates were compared with 11 primates receiving allo-HCT transplants that received supportive care only.
Primates receiving three weekly doses of REGN421 showed antibody concentrations of greater than 2 mcg/mL for more than 30 days post HCT. A single dose of REGN421 was associated with protection from acute GVHD at day 0, while three weekly doses showed protection at day 0, 7, and 14, consistent with an impact of REGN421 during the early phases of T-cell activation.
Compared with animals receiving only supportive care, prophylaxis with REGN421 was associated with delayed acute GVHD onset and lengthened survival.
Of the 11 primates treated with REGN421, none developed clinical signs of gastrointestinal acute GVHD, whereas the majority of those receiving standard care or other preventive interventions did.
“Detailed analysis of acute GVHD clinical presentations in REGN421-treated animals in comparison to no treatment controls revealed near complete protection from GI-acute GvHD with REGN421,” the authors reported.
Furthermore, pathology scores in the gastrointestinal tract were lower with REGN421 treatment, compared with the no-treatment cohort, and the scores matched those of healthy nontransplanted nonhuman primates.
The primates treated with REGN421 did ultimately develop other clinical and pathologic signs of skin, hepatic or pulmonary acute GVHD, but without gastrointestinal disease.
The treatment was not associated with any adverse effects on the allo-HCT, with primates receiving either a single dose or three weekly doses of REGN421 showing rapid donor engraftment after allo-HCT, including high bone marrow, whole blood, and T-cell donor chimerism.

ESMO helps hematologists assess new cancer drugs
It consists of 11 2- to 3-page forms with checklists to grade treatment trials on the extent to which they meet efficacy and safety thresholds. Each of the 11 forms covers a specific trial scenario, such as a randomized controlled trial with curative intent or a trial of a therapy that is not likely to be curative with a primary endpoint of overall survival.
Treatments with curative intent are graded A, B, or C, while treatments in the noncurative setting are graded on a descending scale from 5 to 1. Scores of A and B in the curative setting and 5 and 4 in the noncurative setting represent substantial benefit.
On the form for RCTs with curative intent, for instance, a survival improvement of 5% or more garners an A but an improvement of less than 3% gets a C. Scores are also annotated for serious acute and/or persistent toxicity if present.
The tool, dubbed the ESMO-MCBS:H (European Society for Medical Oncology Magnitude of Clinical Benefit Scale: Hematology), is explained in an article published in Annals of Oncology. The evaluation forms are available online.
The idea behind the work is to help health care professionals and others to more “accurately assess the value of and prioritise therapies for patients with blood cancers. For clinicians, ESMO-MCBS:H will aid in their clinical decision-making and in the development of evidence-based practice and guidelines,” ESMO said in a press release.
To develop ESMO-MCBS:H, the group tailored its tool for evaluating solid tumor therapies, the ESMO-MCBS, to account for the sometimes different endpoints used in hematologic malignancy trials and the very indolent nature of some blood cancers, such as follicular lymphoma, which hampers development of mature data.
Specific changes include adding a new evaluation form to grade single-arm trials with curative intent, such as those used for CAR-T-cell therapies; incorporating molecular surrogate endpoints used in CML trials; and adding a way to grade outcomes for indolent cancers, among others.
The development process included applying the solid tumor tool to 80 blood cancer studies to identify shortcomings and improve its applicability. The final tool was field tested with 51 international experts from EHA and ESMO who largely agreed on the reasonableness of the trial scores.
ESMO said it expects ESMO-MCBS:H will be useful. The solid tumor tool, first published in 2015, is used by the World Health Organization to screen medications for its essential medicines list as well as by ESMO to generate guidelines and oncology centers across Europe to help with resource allocation decisions.

Multiprong strategy makes clinical trials less White
CHICAGO – Clinical trials are so White. Only a small percentage of eligible patients participate in clinical trials in the first place, and very few come from racial and ethnic minority groups.
For example, according to the Food and Drug Administration, in trials that resulted in drug approvals from 2017 to 2020, only 2%-5% of participants were Black patients.
When clinical trials lack diverse patient populations, those who are left out have fewer opportunities to get new therapies. Moreover, the scope of the research is limited by smaller phenotypic and genotypic samples, and the trial results are applicable only to more homogeneous patient groups.
There has been a push to include more underrepresented patients in clinical trials. One group reported its success in doing so here at the annual meeting of the American Society of Clinical Oncology.
a period that included a pandemic-induced hiatus in clinical trials in general.
Alliance member Electra D. Paskett, PhD, from the College of Public Health at the Ohio State University in Columbus, presented accrual data from 117 trials led by the Alliance from 2014 to 2022.
During this period, accrual of racial and ethnic minority patients increased from 13.6% to 25.3% for cancer treatment trials and from 13% to 21.5% for cancer control trials.
Overall, the recruitment program resulted in an absolute increase from 13.5 % to 23.6% of underrepresented populations, which translated into a relative 74.8% improvement.
“We’re focusing now on monitoring accrual of women, rural populations, younger AYAs [adolescents and young adults] and older patients, and we’ll see what strategies we need to implement,” Dr. Packett told this news organization.
The Alliance has implemented a real-time accrual dashboard on its website that allows individual sites to review accrual by trial and overall for all of the identified underrepresented populations, she noted.
Program to increase underrepresented patient accrual
The impetus for the program to increase enrollment of underrepresented patients came from the goal set by Monica M. Bertagnolli, MD, group chair of the Alliance from 2011 to 2022 and currently the director of the U.S. National Cancer Institute.
“Our leader, Dr. Bertagnolli, set out a group-wide goal for accrual of underrepresented minorities to our trials of 20%, and that gave us permission to implement a whole host of new strategies,” Dr. Paskett said in an interview.
“These strategies follow the Accrual of Clinical Trials framework, which essentially says that the interaction between the patient and the provider for going on a clinical trial is not just an interaction between the patient and provider but recognizes, for example, that the provider has coworkers and they have norms and beliefs and attitudes, and the patient comes from a family with their own values. And then there are system-level barriers, and there are community barriers that all relate to this interaction about going on a trial,” Dr. Packett said.
What works?
The study was presented as a poster at the meeting. During the poster discussion session, comoderator Victoria S. Blinder, MD, from Memorial Sloan Kettering Cancer Center in New York, asked Dr. Paskett, “If you had a certain amount of money and you really wanted to use that resource to focus on one area, where would you put that resource?”
“I’m going to violate the rules of your question,” Dr. Paskett replied.
“You cannot change this problem by focusing on one thing, and that’s what we showed in our Alliance poster, and what I’ve said is based on over 30 years of work in this area,” she said.
She cited what she considered as the two most important components for improving accrual of underrepresented populations: a commitment by leadership to a recruitment goal, and the development of protocols with specific accrual goals for minority populations.
Still, those are only two components of a comprehensive program that includes the aforementioned accrual goal set by Dr. Bertagnolli, as well as the following:
- Funding of minority junior investigators and research that focuses on issues of concern to underrepresented populations.
- Establishment of work groups that focus on specific populations with the Alliance health disparities committee.
- Translation of informational materials for patients.
- Opening studies at National Cancer Institute Community. Oncology Research Program–designated minority underserved sites.
- Real-time monitoring of accrual demographics by the Alliance and at the trial site.
- Closing protocol enrollment to majority populations.
- Increasing the study sample sizes to enroll additional minority participants and to allow for subgroup analyses.
The study was funded by the National Institutes of Health. Dr. Packett and Dr. Blinder reported no relevant financial relationships.

CBSM phone app eases anxiety, depression in cancer patients
CHICAGO – One-third of patients with cancer also experience anxiety or depression, and an estimated 70% of the 18 million patients with cancer and cancer survivors in the US experience emotional symptoms, including fear of recurrence.
Despite many having these symptoms, few patients with cancer have access to psycho-oncologic support.
A digital cognitive-behavioral stress management (CBSM) application may help to ease some of the burden, reported Allison Ramiller, MPH, of Blue Note Therapeutics in San Francisco, which developed the app version of the program.
In addition, patients assigned to the CBSM app were twice as likely as control persons to report that their symptoms were “much” or “very much” improved after using the app for 12 weeks, Ms. Ramiller reported at an oral abstract session at the annual meeting of the American Society of Clinical Oncology (ASCO).
However, the investigators did not report baseline characteristics of patients in each of the study arms, which might have helped to clarify the depth of the effects they saw.
The CBSM program was developed by Michael H. Antoni, PhD, and colleagues in the University of Miami Health System. It is based on cognitive-behavioral therapy but also includes stress management and relaxation techniques to help patients cope with cancer-specific stress.
“”It has been clinically validated and shown to benefit patients with cancer,” Ms. Ramiller said. “However, access is a problem,” she said.
“There aren’t enough qualified, trained providers for the need, and patients with cancer encounter barriers to in-person participation, including things like transportation or financial barriers. So to overcome this, we developed a digitized version of CBSM,” she explained.
Impressive and elegant
“Everything about [the study] I thought was very impressive, very elegant, very nicely done,” said invited discussant Raymond U. Osarogiagbon, MBBS, FACP, chief scientist at Baptist Memorial Health Care Corp in Memphis, Tenn.
“They showed efficacy, they showed safety – very nice – user friendliness – very good. Certainly they look like they’re trying to address a highly important, unmet need in a very elegant way. Certainly, they pointed out it needs longer follow-up to see sustainability. We need to see will this work in other settings. Will this be cost-effective? You’ve gotta believe it probably will be,” he said.
CBSM has previously been shown to help patients with cancer reduce stress, improve general and cancer-specific quality of life at various stages of treatment, reduce symptom burden, and improve coping skills, Ms. Ramiller said.
To see whether these benefits could be conveyed digitally rather than in face-to-face encounters, Ms. Ramiller and colleagues worked with Dr. Antoni to develop the CBSM app.
Patients using the app received therapeutic content over 10 sessions with audio, video, and interactive tools that mimicked the sessions they would have received during in-person interventions.
They then compared the app against the control educational app in the randomized, decentralized RESTORE study.
High-quality control
Ms. Ramiller said that the control app set “a high bar.”
“The control also offered 10 interactive self-guided sessions. Both treatment apps were professionally designed and visually similar in styling, and they were presented as digital therapeutic-specific for cancer patients. And they were also in a match condition, meaning they received the same attention from study staff and cadence of reminders, but importantly, only the intervention app was based on CBSM,” she explained.
A total of 449 patients with cancers of stage I–III who were undergoing active systemic treatment or were planning to undergo such treatment within 6 months were randomly assigned to the CBSM app or the control app.
The CBSM app was superior to the control app for the primary outcome of anxiety reduction over baseline, as measured at 4, 8 and 12 weeks by the Patient-Reported Outcomes Measurement Information System Anxiety Scale (PROMIS-A) (beta = -.03; P = .019).
CBSM was also significantly better than the control app for the secondary endpoints of reducing symptoms of depression, as measured by the PROMIS-D scale (beta = -.02, P = .042), and also at increasing the percentage of patients who reported improvement in anxiety and depression symptoms on the Patient Global Impression of Change instrument (P < .001)
An extension study of the durability of the effects at 3 and 6 months is underway.
The investigators noted that the incremental cost of management of anxiety or depression is greater than $17,000 per patient per year.
“One of the big promises of a digital therapeutic like this is that it could potentially reduce costs,” Ms. Ramiller told the audience, but she acknowledged, “More work is really needed, however, to directly test the potential savings.”
The RESTORE study is funded by Blue Note Therapeutics. Dr. Osarogiagbon owns stock in Gilead, Lilly, and Pfizer, has received honoraria from Biodesix and Medscape, and has a consulting or advisory role for the American Cancer Society AstraZeneca, Genentech/Roche, LUNGevity, National Cancer Institute, and Triptych Health Partners.

Huge underuse of germline testing for cancer patients
Information from germline genetic testing could affect a patient’s cancer care. For example, such testing could indicate that targeted therapies would be beneficial, and it would have implications for close relatives who may carry the same genes.
The finding that so few patients with newly diagnosed cancer were tested comes from an analysis of data on more than 1.3 million individuals across two U.S. states. The data were taken from the Surveillance, Epidemiology, and End Results (SEER) registry.
The rate is “well below guideline recommendations,” said study presenter Allison W. Kurian, MD, department of medicine, Stanford (Calif.) University.
“Innovative care delivery” is needed to tackle the problem, including the streamlining of pretest counseling, making posttest counseling more widely available, and employing long-term follow-up to track patient outcomes, she suggested.
“I do think this is a time for creative solutions of a number of different kinds,” she said. She suggested that lessons could be learned from the use of telemedicine during the COVID-19 pandemic. She also noted that “there have been some interesting studies on embedding genetic counselors in oncology clinics.”
Dr. Kurian presented the study at the annual meeting of the American Society of Clinical Oncology (ASCO). The study was simultaneously published in the Journal of the American Medical Association.
The current results represent a “missed opportunity for decrease the population-level burden of cancer,” experts noted in an accompanying editorial.
“Clinicians should recommend testing to their patients and provide them with the information necessary to make informed decisions about whether to undergo testing,” Zsofia K. Stadler, MD, and Deborah Schrag, MD, MPH, of Memorial Sloan Kettering Cancer Center, New York, wrote in their editorial.
They suggested novel approaches to widen access, such as use of point-of-care testing, telecounseling, and, in the future, chatbots to respond to patient questions.
“With greater emphasis on overcoming both health system and patient-level barriers to genetic cancer susceptibility testing for patients with cancer, treatment outcomes will improve and cancer diagnoses and related deaths in family members will be prevented,” they concluded.
At the meeting, invited discussant Erin Frances Cobain, MD, assistant professor of medical oncology, University of Michigan Health, Ann Arbor, referring to breast cancer as an example, said that progress has “stagnated” in recent years.
The study found a higher rate of gene testing among patients with newly diagnosed breast cancer, at just over 20%.
Dr. Cobain argued that this was still too low. She pointed out that “a recent study suggested that over 60% of individuals with an incident cancer diagnosis would meet criteria for genetic testing by National Comprehensive Cancer Network guidelines.
“This may be because testing is not offered, there may be poor access to genetic counseling resources, or patients may be offered testing but decline it,” she suggested.
One compelling reason to conduct genetic testing for patients newly diagnosed with breast cancer is that it may show that they are candidates for treatment with PARP (poly[ADP]-ribose polymerase) inhibitors, which “may have a direct impact on cancer-related mortality,” she pointed out.
“We need increased awareness and access to genetic testing resources for patients with breast cancer, particularly for racial and ethnic minorities,” she said.
Dr. Cobain also noted that finding variants of uncertain significance (VUS) was more likely among patients from racial and ethnic minorities than among White patients. She said such a finding “increases patient and physician anxiety,” and there may be “unclear optimal management recommendations for these patients.”
Details of the study
Germline genetic testing is “increasingly essential for cancer care,” Dr. Kurian said.
It is central to risk-adapted screening and secondary prevention, the use of targeted therapies, including PARP and checkpoint inhibitors, and cascade testing to identify at-risk relatives.
She pointed out that in clinical practice, testing has “evolved rapidly.” Panels include more and more genes. In addition, the cost of these tests is falling, and guidelines have become “more expansive.”
However, “little is known about genetic testing use and results,” Dr. Kurian noted.
The team therefore undertook the SEER-GeneLINK initiative, which involved patients aged ≥ 20 years who were diagnosed with cancer between Jan. 1, 2013, and March 31, 2019, and who were reported to statewide SEER registries in California and Georgia.
The team looked for patients for whom germline genetic test results had been reported by the four laboratories that performed the majority of patient testing in the two states. Results were categorized as pathogenic, benign, or VUS.
The results were classified on the basis of current guidelines for testing and/or management as related to breast/ovarian cancer, gastrointestinal cancer, other hereditary cancers, or those with no guidelines for testing or management.
Dr. Kurian reported that from an overall population of 1,412,388 patients diagnosed with cancer, 1,369,660 were eligible for inclusion. Of those, about half (51.9%) were women, and the majority (86.3%) were aged 50 years or older.
Many of these patients (61.4%) were non-Hispanic White persons, and slightly fewer than half (49.8%) were deemed to be in medium or high poverty, as determined using U.S. Census tract levels.
Overall, germline genetic testing was performed in 93,052 (6.8%) of patients over the study period.
Women were more likely to have undergone germline mutation testing than men, at 13.9% vs. 2.2%, as were patients aged 20-49 years, at 22.1% vs. 8.2% for those aged 50-69 years, and 3.3% for those aged 70 years and older.
The number of genes for which testing was conducted increased from a median of 2 in 2013 to 34 in 2019. Rates of VUS increased more than that for pathologic variants and substantially more so in non-White patients.
By 2019, the ratio of VUS to pathologic variants stood at 1.7 among White patients, vs. 3.9 among Asian patients, 3.6 among Black patients, and 2.2 among Hispanic patients.
The majority of identified pathologic variants that were related to the diagnosed cancer and genes with testing and/or management guidelines accounted for 67.5% to 94.9% of such variants.
Regarding specific cancer diagnoses, Dr. Kurian said that over the course of the study period, testing rates consistently exceeded 50% only among male breast cancer patients.
There were rapid increases in testing for ovarian cancer, from 28.0% of cases in 2013 to 54.0% in 2019. For pancreatic cancer, rates increased from 1.0% to 19.0% over the same period, and for prostate cancer, rates increased from 0.1% to 4.0%. She suggested that these increases in rates may be related to the approval of PARP inhibitors for use in these indications.
However, there was little change in the rates of germline mutation testing for lung cancer patients, from 01% in 2013 to 0.8% in 2019, and for other cancers, from 0.3% to 2.0%.
The results also revealed racial and ethnic differences in testing after controlling for age, cancer type, and year. Over the course of the study period, 8.0% of White patients underwent genetic testing, compared with 6.0% each for Asian, Black, and Hispanic patients and 5.0% for other patients (P < .001).
With regard specifically to male and female breast cancer and ovarian cancer, testing rates were 31% among White patients, 22% for Asian patients, 25% for Black patients, and 23% for Hispanic patients (P < .001).
Dr. Kurian acknowledged that the study is limited by a lack of testing from other laboratories and direct-to-consumer test data, although a recent survey suggested that this represents fewer than 5% of all germline genetic tests.
She also noted that the SEER registries do not collect data on family history or tumor sequencing.
The study was funded by the National Institutes of Health, and the Centers for Disease Control and Prevention. Dr. Kurian has relationships with Adela, Ambry Genetics, Color Genomics, GeneDx/BioReference, Genentech, InVitae, and Myriad Genetics. Other authors report numerous relationships with industry. Dr. Cobain has ties with AstraZeneca, Daiichi Sankyo, Athenex, Ayala Pharmaceuticals, bioTheranostics, and Immunomedics. Dr. Schrag has relationships with Merck, JAMA, AACR, and Grail. Dr. Stadler has ties with Adverum Biotechnologies, Genentech, Neurogene, Novartis, Optos Plc, Outlook Therapeutics, and Regeneron Pharmaceuticals.

Dr. Cobain also noted that finding variants of uncertain significance (VUS) was more likely among patients from racial and ethnic minorities than among White patients. She said such a finding “increases patient and physician anxiety,” and there may be “unclear optimal management recommendations for these patients.”
Details of the study
Germline genetic testing is “increasingly essential for cancer care,” Dr. Kurian said.
It is central to risk-adapted screening and secondary prevention, the use of targeted therapies, including PARP and checkpoint inhibitors, and cascade testing to identify at-risk relatives.
She pointed out that in clinical practice, testing has “evolved rapidly.” Panels include more and more genes. In addition, the cost of these tests is falling, and guidelines have become “more expansive.”
However, “little is known about genetic testing use and results,” Dr. Kurian noted.
The team therefore undertook the SEER-GeneLINK initiative, which involved patients aged ≥ 20 years who were diagnosed with cancer between Jan. 1, 2013, and March 31, 2019, and who were reported to statewide SEER registries in California and Georgia.
The team looked for patients for whom germline genetic test results had been reported by the four laboratories that performed the majority of patient testing in the two states. Results were categorized as pathogenic, benign, or VUS.
The results were classified on the basis of current guidelines for testing and/or management as related to breast/ovarian cancer, gastrointestinal cancer, other hereditary cancers, or those with no guidelines for testing or management.
Dr. Kurian reported that from an overall population of 1,412,388 patients diagnosed with cancer, 1,369,660 were eligible for inclusion. Of those, about half (51.9%) were women, and the majority (86.3%) were aged 50 years or older.
Many of these patients (61.4%) were non-Hispanic White persons, and slightly fewer than half (49.8%) were deemed to be in medium or high poverty, as determined using U.S. Census tract levels.
Overall, germline genetic testing was performed in 93,052 (6.8%) of patients over the study period.
Women were more likely to have undergone germline mutation testing than men, at 13.9% vs. 2.2%, as were patients aged 20-49 years, at 22.1% vs. 8.2% for those aged 50-69 years, and 3.3% for those aged 70 years and older.
The number of genes for which testing was conducted increased from a median of 2 in 2013 to 34 in 2019. Rates of VUS increased more than that for pathologic variants and substantially more so in non-White patients.
By 2019, the ratio of VUS to pathologic variants stood at 1.7 among White patients, vs. 3.9 among Asian patients, 3.6 among Black patients, and 2.2 among Hispanic patients.
The majority of identified pathologic variants that were related to the diagnosed cancer and genes with testing and/or management guidelines accounted for 67.5% to 94.9% of such variants.
Regarding specific cancer diagnoses, Dr. Kurian said that over the course of the study period, testing rates consistently exceeded 50% only among male breast cancer patients.
There were rapid increases in testing for ovarian cancer, from 28.0% of cases in 2013 to 54.0% in 2019. For pancreatic cancer, rates increased from 1.0% to 19.0% over the same period, and for prostate cancer, rates increased from 0.1% to 4.0%. She suggested that these increases in rates may be related to the approval of PARP inhibitors for use in these indications.
However, there was little change in the rates of germline mutation testing for lung cancer patients, from 01% in 2013 to 0.8% in 2019, and for other cancers, from 0.3% to 2.0%.
The results also revealed racial and ethnic differences in testing after controlling for age, cancer type, and year. Over the course of the study period, 8.0% of White patients underwent genetic testing, compared with 6.0% each for Asian, Black, and Hispanic patients and 5.0% for other patients (P < .001).
With regard specifically to male and female breast cancer and ovarian cancer, testing rates were 31% among White patients, 22% for Asian patients, 25% for Black patients, and 23% for Hispanic patients (P < .001).
Dr. Kurian acknowledged that the study is limited by a lack of testing from other laboratories and direct-to-consumer test data, although a recent survey suggested that this represents fewer than 5% of all germline genetic tests.
She also noted that the SEER registries do not collect data on family history or tumor sequencing.
