BMS Phase 3 Trial Evaluating Breyanzi Vs Chemotherapy in Refractory Lymphoma

June 10, 2021: “Bristol Myers Squibb announced positive topline results from TRANSFORM, a global, randomized, multicenter Phase 3 study evaluating Breyanzi (lisocabtagene maraleucel) as a second-line treatment in adults with relapsed or refractory large B-cell lymphoma (LBCL) compared to salvage therapy followed by high-dose chemotherapy and hematopoietic stem cell transplant, which is currently considered a gold standard treatment for these patients.

Results of a pre-specified interim analysis conducted by an independent review committee showed the study met its primary endpoint of demonstrating a clinically meaningful and highly statistically significant improvement in event-free survival, as well as key secondary endpoints of complete response rate and progression-free survival compared to standard of care.

Overall survival data were immature at the time of this interim analysis. Safety results were consistent with the known safety profile of Breyanzi for the treatment of LBCL in the third-line setting, and no new safety concerns were identified in this second-line setting.

“We ambitiously designed the TRANSFORM trial to evaluate Breyanzi’s potential in the second-line setting for patients with relapsed or refractory large B-cell lymphoma against the standard of care regimen of high-dose chemotherapy and autologous stem cell transplant,” said Noah Berkowitz, M.D., Ph.D., senior vice president, Hematology and Cell Therapy Development, Bristol Myers Squibb.

“These positive interim results build on our commitment to bring CAR T cell therapies into earlier lines and highlight the potential of Breyanzi to transform the treatment paradigm for this difficult-to-treat disease, possibly supplanting the need for patients to undergo current aggressive treatment regimens.”

The results represent the first time a therapy has shown a benefit over standard of care high-dose chemotherapy and stem cell transplant in relapsed or refractory LBCL, and the first time a CD19-directed CAR T cell therapy has demonstrated potential as a second-line therapy in this patient population.

The company will complete an evaluation of the TRANSFORM data and looks forward to sharing the results at an upcoming medical conference, as well as with health authorities.

Bristol Myers Squibb thanks the patients and investigators who are participating in the TRANSFORM clinical trial.

Breyanzi, a CD19-directed CAR T cell therapy,was approved by the U.S. FDA in February 2021 for the treatment of adult patients with relapsed or refractory LBCL after two or more lines of systemic therapy, including diffuse large B-cell lymphoma (DLBCL) not otherwise specified (including DLBCL arising from indolent lymphoma), high-grade B-cell lymphoma, primary mediastinal large B-cell lymphoma, and follicular lymphoma grade 3B. 

Breyanzi is not indicated for the treatment of patients with primary central nervous system lymphoma.

About TRANSFORM

TRANSFORM (NCT03575351) is a pivotal, global, randomized, multicenter Phase 3 trial evaluating Breyanzi compared to current standard of care regimens, including high-dose chemotherapy (HDCT) and hematopoietic stem cell transplant (HSCT), in adults with large B-cell lymphoma that is primary refractory or relapsed within 12 months of initial therapy and who are eligible for stem cell transplant.

Patients were randomized to receive Breyanzi or standard of care salvage therapy, including rituximab plus dexamethasone, high-dose cytarabine, and cisplatin (R-DHAP), rituximab plus ifosfamide, carboplatin and etoposide (R-ICE), or rituximab plus gemcitabine, dexamethasone and cisplatin (R-GDP) per the investigators’ choice before proceeding to HDCT and HSCT.

The primary endpoint of the study is event-free survival, defined as time from randomization to death from any cause, progressive disease, failure to achieve complete response or partial response by nine weeks post-randomization, or start of new antineoplastic therapy due to efficacy concerns, whichever occurs first.

Complete response rate is a key secondary endpoint. Other efficacy endpoints include progression-free survival, overall survival, overall response rate and duration of response.

All enrolled patients have large B-cell lymphoma and were relapsed or refractory within 12 months from CD20 antibody and anthracycline containing first-line therapy.

About Breyanzi

Breyanzi is a CD-19 directed chimeric antigen receptor (CAR) T cell therapy with a defined composition and 4-1BB costimulatory domain. Breyanzi is administered as a defined composition to reduce variability of the CD8 and CD4 component dose.

The 4-1BB signaling domain enhances the expansion and persistence of the CAR- T cells.

Breyanzi is approved by the U.S.FDA for the treatment of adult patients with relapsed or refractory LBCL after two or more lines of systemic therapy, including diffuse large B-cell lymphoma (DLBCL) not otherwise specified (including DLBCL arising from indolent lymphoma), high-grade B-cell lymphoma, primary mediastinal large B-cell lymphoma, and follicular lymphoma grade 3B.

Breyanzi is also approved in Japan for relapsed and refractory LBCL, and Marketing Authorization Applications for Breyanzi are currently under review in the European Union, Switzerland and Canada.

Bristol Myers Squibb’s clinical development program for Breyanzi includes clinical studies in earlier lines of treatment for patients with relapsed or refractory LBCL and other types of lymphoma. For more information, visit clinicaltrials.gov.

U.S. FDA-Approved Indication for Breyanzi

BREYANZI is a CD19-directed genetically modified autologous T cell immunotherapy indicated for the treatment of adult patients with relapsed or refractory (R/R) large B-cell lymphoma after two or more lines of systemic therapy, including diffuse large B-cell lymphoma (DLBCL) not otherwise specified (including DLBCL arising from indolent lymphoma), high-grade B-cell lymphoma, primary mediastinal large B-cell lymphoma, and follicular lymphoma grade 3B.

Limitations of Use: BREYANZI is not indicated for the treatment of patients with primary central nervous system lymphoma.

Important Safety Information

BOXED WARNING: CYTOKINE RELEASE SYNDROME and NEUROLOGIC TOXICITIES

  • Cytokine Release Syndrome (CRS), including fatal or life-threatening reactions, occurred in patients receiving BREYANZI.

    Do not administer BREYANZI to patients with active infection or inflammatory disorders. Treat severe or life-threatening CRS with tocilizumab with or without corticosteroids.
  • Neurologic toxicities, including fatal or life-threatening reactions, occurred in patients receiving BREYANZI, including concurrently with CRS, after CRS resolution or in the absence of CRS.

    Monitor for neurologic events after treatment with BREYANZI. Provide supportive care and/or corticosteroids as needed.
  • BREYANZI is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called the BREYANZI REMS.

Cytokine Release Syndrome (CRS)

CRS, including fatal or life-threatening reactions, occurred following treatment with BREYANZI. CRS occurred in 46% (122/268) of patients receiving BREYANZI, including ≥ Grade 3 (Lee grading system) CRS in 4% (11/268) of patients.

One patient had fatal CRS and 2 had ongoing CRS at time of death.

The median time to onset was 5 days (range: 1 to 15 days). CRS resolved in 119 of 122 patients (98%) with a median duration of 5 days (range: 1 to 17 days).

Median duration of CRS was 5 days (range 1 to 30 days) in all patients, including those who died or had CRS ongoing at time of death.

Among patients with CRS, the most common manifestations of CRS include fever (93%), hypotension (49%), tachycardia (39%), chills (28%), and hypoxia (21%)

Serious events that may be associated with CRS include cardiac arrhythmias (including atrial fibrillation and ventricular tachycardia), cardiac arrest, cardiac failure, diffuse alveolar damage, renal insufficiency, capillary leak syndrome, hypotension, hypoxia, and hemophagocytic lymphohistiocytosis/macrophage activation syndrome (HLH/MAS).

Ensure that 2 doses of tocilizumab are available prior to infusion of BREYANZI. Sixty-one of 268 (23%) patients received tocilizumab and/or a corticosteroid for CRS after infusion of BREYANZI.

Twenty-seven (10%) patients received tocilizumab only, 25 (9%) received tocilizumab and a corticosteroid, and 9 (3%) received corticosteroids only.

Neurologic Toxicities

Neurologic toxicities that were fatal or life-threatening, occurred following treatment with BREYANZI.

CAR T cell-associated neurologic toxicities occurred in 35% (95/268) of patients receiving BREYANZI, including ≥ Grade 3 in 12% (31/268) of patients. Three patients had fatal neurologic toxicity and 7 had ongoing neurologic toxicity at time of death.

The median time to onset of the first event was 8 days (range: 1 to 46 days).

The onset of all neurologic events occurred within the first 8 weeks following BREYANZI infusion. Neurologic toxicities resolved in 81 of 95 patients (85%) with a median duration of 12 days (range: 1 to 87 days).

Three of four patients with ongoing neurologic toxicity at data cutoff had tremor and one subject had encephalopathy.

Median duration of neurologic toxicity was 15 days (range: 1 to 785 days) in all patients, including those with ongoing neurologic events at the time of death or at data cutoff.

Seventy-eight (78) of 95 (82%) patients with neurologic toxicity experienced CRS. Neurologic toxicity overlapped with CRS in 57 patients.

The onset of neurologic toxicity was after onset of CRS in 30 patients, before CRS onset in 13 patients, same day as CRS onset in 7 patients, and same day as CRS resolution in 7 patients.

Neurologic toxicity resolved in three patients before the onset of CRS. Eighteen patients experienced neurologic toxicity after resolution of CRS.

The most common neurologic toxicities included encephalopathy (24%), tremor (14%), aphasia (9%), delirium (7%), headache (7%), dizziness (6%), and ataxia (6%).

Serious events including cerebral edema and seizures occurred with BREYANZI. Fatal and serious cases of leukoencephalopathy, some attributable to fludarabine, have occurred in patients treated with BREYANZI.

CRS and Neurologic Toxicities Monitoring

Monitor patients daily at a certified healthcare facility during the first week following infusion, for signs and symptoms of CRS and neurologic toxicities.

Monitor patients for signs and symptoms of CRS and neurologic toxicities for at least 4 weeks after infusion; evaluate and treat promptly.

Counsel patients to seek immediate medical attention should signs or symptoms of CRS or neurologic toxicity occur at any time.

At the first sign of CRS, institute treatment with supportive care, tocilizumab or tocilizumab and corticosteroids as indicated.

BREYANZI REMS

Because of the risk of CRS and neurologic toxicities, BREYANZI is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called the BREYANZI REMS. The required components of the BREYANZI REMS are:

  • Healthcare facilities that dispense and administer BREYANZI must be enrolled and comply with the REMS requirements.
  • Certified healthcare facilities must have on-site, immediate access to tocilizumab.
  • Ensure that a minimum of 2 doses of tocilizumab are available for each patient for infusion within 2 hours after BREYANZI infusion, if needed for treatment of CRS.
  • Certified healthcare facilities must ensure that healthcare providers who prescribe, dispense, or administer BREYANZI are trained on the management of CRS and neurologic toxicities.

Hypersensitivity Reactions

Allergic reactions may occur with the infusion of BREYANZI. Serious hypersensitivity reactions, including anaphylaxis, may be due to dimethyl sulfoxide (DMSO).

Serious Infections

Severe infections, including life-threatening or fatal infections, have occurred in patients after BREYANZI infusion. Infections (all grades) occurred in 45% (121/268) of patients. Grade 3 or higher infections occurred in 19% of patients.

Grade 3 or higher infections with an unspecified pathogen occurred in 16% of patients, bacterial infections occurred in 5%, and viral and fungal infections occurred in 1.5% and 0.4% of patients, respectively. Monitor patients for signs and symptoms of infection before and after BREYANZI administration and treat appropriately.

Administer prophylactic antimicrobials according to standard institutional guidelines.

Febrile neutropenia has been observed in 9% (24/268) of patients after BREYANZI infusion and may be concurrent with CRS. In the event of febrile neutropenia, evaluate for infection and manage with broad spectrum antibiotics, fluids, and other supportive care as medically indicated.

Avoid administration of BREYANZI in patients with clinically significant active systemic infections.

Viral reactivation: Hepatitis B virus (HBV) reactivation, in some cases resulting in fulminant hepatitis, hepatic failure, and death, can occur in patients treated with drugs directed against B cells.

Ten of the 11 patients in the TRANSCEND study with a prior history of HBV were treated with concurrent antiviral suppressive therapy to prevent HBV reactivation during and after treatment with BREYANZI.

Perform screening for HBV, HCV, and HIV in accordance with clinical guidelines before collection of cells for manufacturing.

Prolonged Cytopenias

Patients may exhibit cytopenias not resolved for several weeks following lymphodepleting chemotherapy and BREYANZI infusion. Grade 3 or higher cytopenias persisted at Day 29 following BREYANZI infusion in 31% (84/268) of patients, and included thrombocytopenia (26%), neutropenia (14%), and anemia (3%). Monitor complete blood counts prior to and after BREYANZI administration.

Hypogammaglobulinemia

B-cell aplasia and hypogammaglobulinemia can occur in patients receiving treatment with BREYANZI. The adverse event of hypogammaglobulinemia was reported as an adverse reaction in 14% (37/268) of patients; laboratory IgG levels fell below 500 mg/dL after infusion in 21% (56/268) of patients.

Hypogammaglobulinemia, either as an adverse reaction or laboratory IgG level below 500 mg/dL after infusion, was reported in 32% (85/268) of patients.

Monitor immunoglobulin levels after treatment with BREYANZI and manage using infection precautions, antibiotic prophylaxis, and immunoglobulin replacement as clinically indicated.

Live vaccines: The safety of immunization with live viral vaccines during or following BREYANZI treatment has not been studied.

Vaccination with live virus vaccines is not recommended for at least 6 weeks prior to the start of lymphodepleting chemotherapy, during BREYANZI treatment, and until immune recovery following treatment with BREYANZI.

Secondary Malignancies

Patients treated with BREYANZI may develop secondary malignancies. Monitor lifelong for secondary malignancies. In the event that a secondary malignancy occurs, contact Bristol Myers Squibb at 1-888-805-4555 for reporting and to obtain instructions on collection of patient samples for testing.

Effects on Ability to Drive and Use Machines

Due to the potential for neurologic events, including altered mental status or seizures, patients receiving BREYANZI are at risk for altered or decreased consciousness or impaired coordination in the 8 weeks following BREYANZI administration.

Advise patients to refrain from driving and engaging in hazardous occupations or activities, such as operating heavy or potentially dangerous machinery, during this initial period.

Adverse Reactions

Serious adverse reactions occurred in 46% of patients. The most common nonlaboratory, serious adverse reactions (> 2%) were CRS, encephalopathy, sepsis, febrile neutropenia, aphasia, pneumonia, fever, hypotension, dizziness, and delirium. Fatal adverse reactions occurred in 4% of patients.

The most common nonlaboratory adverse reactions of any grade (≥ 20%) were fatigue, CRS, musculoskeletal pain, nausea, headache, encephalopathy, infections (pathogen unspecified), decreased appetite, diarrhea, hypotension, tachycardia, dizziness, cough, constipation, abdominal pain, vomiting, and edema.”
