Approval of Breyanzi based on the pivotal Phase 3 TRANSFORM trial, in which Breyanzi significantly improved event-free survival compared to standard of care with a manageable and well-established safety profile

PRINCETON, NJ, USA I May 03, 2023 IBristol Myers Squibb (NYSE: BMY) today announced that the European Commission (EC) has granted approval for Breyanzi (lisocabtagene maraleucel; liso-cel), a CD19-directed chimeric antigen receptor (CAR) T cell therapy, for the treatment of adult patients with diffuse large B-cell lymphoma (DLBCL), high grade B-cell lymphoma (HGBCL), primary mediastinal large B-cell lymphoma (PMBCL) and follicular lymphoma grade 3B (FL3B), who relapsed within 12 months from completion of, or are refractory to, first-line chemoimmunotherapy. This approval covers all European Union (EU) member states.*

The approval is based on results from the pivotal Phase 3 TRANSFORM trial in which Breyanzi demonstrated statistically significant and clinically meaningful improvements in the study’s primary endpoint of event-free survival (EFS), and key secondary endpoints of complete responses (CR) and progression-free survival (PFS) compared to standard therapy (consisting of salvage immunochemotherapy followed by high-dose chemotherapy and hematopoietic stem cell transplant [HSCT]), along with a manageable and well-established safety profile.

“With Breyanzi, people in Europe living with relapsed or refractory DLBCL now have a differentiated CAR T cell therapy option earlier in the treatment paradigm that provides long-term clinical benefit,” said Anne Kerber, senior vice president, head of Cell Therapy Development, Bristol Myers Squibb. “This marks the approval of our third indication in Europe for our CAR T cell therapy portfolio, underscoring our continued drive to deliver the promise of cell therapy with curative potential for more patients.”

In DLBCL, the most common form of non-Hodgkin lymphoma, up to 40% of patients have disease that is refractory to or relapses following initial therapy. The standard therapy for these patients consists of intensive salvage immunochemotherapy followed by high-dose chemotherapy and HSCT for those whose disease responds to the salvage therapy and are eligible for transplant. However, only an estimated 25% of patients are considered eligible for transplant and experience long-term clinical benefit, leaving a continued unmet need for second-line treatment options with curative potential.

“Based on results of the TRANSFORM trial, Breyanzi provides significantly improved outcomes compared to the standard of care that has been in place for decades, along with a well-established safety profile, demonstrating the benefit of using a CAR T cell therapy earlier for patients with relapsed or refractory DLBCL,” said Bertram Glass, M.D., TRANSFORM trial investigator and Chief Physician of the Department of Hematology and Stem Cell Transplantation, Helios Klinikum, Berlin, Germany. “This approval represents a significant milestone for patients with continued progress toward transforming second-line treatment practice to provide a personalized treatment option that offers the potential for durable remission.”

TRANSFORM Clinical Trial Results

In the TRANSFORM study, Breyanzi more than quadrupled median EFS compared to standard therapy (10.1 months vs. 2.3 months [HR: 0.349; 95% CI (0.229-0.530) p<0.0001]) at the time of prespecified interim analysis with a median follow-up of 6.2 months. Results of the primary analysis, with a median follow-up of 17.5 months were consistent with the interim analysis, with median EFS not reached for Breyanzi (95% CI: 9.5-NR) vs. 2.4 months for standard therapy (95% CI: 2.2-4.9). With Breyanzi, the majority (73.9%) of patients achieved a CR compared to less than half (43.5%) of those who were treated with standard therapy. Median PFS was not reached (95% CI: 12.6-NR) with Breyanzi vs. 6.2 months (95% CI: 4.3-8.6) with standard therapy (HR: 0.400; 95% CI: 0.261-0.615; p<0.0001).

The safety profile of Breyanzi is well-established, and in the TRANSFORM study, occurrences of cytokine release syndrome (CRS) and neurologic events were generally low-grade, and mostly resolved quickly with standard protocols and without the use of prophylactic steroids. Any-grade CRS was reported in less than half of patients (48.9%), with Grade 3 CRS reported in 1% of patients. The median time to onset of CRS was five days (range: 1 to 63) and median duration of CRS was four days (range: 1 to 16). Any-grade neurologic events were reported in 10.9% of patients treated with Breyanzi, with Grade 3 neurologic events reported in 4.3% of patients. The median time to onset of neurologic events was 11 days (range: 7 to 17 days). The median duration of neurologic toxicities was 4.5 days (range: 1 to 30 days).

TRANSFORM (NCT03575351) is a pivotal, global, randomized, multicenter Phase 3 trial evaluating Breyanzi compared to current standard of care (platinum-based salvage chemotherapy followed by high-dose chemotherapy and autologous hematopietic stem cell transplant [HSCT] in patients responding to salvage chemotherapy) in patients with large B-cell lymphoma that was primary refractory or relapsed within 12 months after CD20-antibody and anthracycline containing first-line therapy. 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 high-dose chemotherapy (HDCT) and auto-HSCT. The primary endpoint of the study was event-free survival, defined as time from randomization to death from any cause, progressive disease, failure to achieve complete response or partial response, or start of new antineoplastic therapy due to efficacy concerns, whichever occurs first. Complete response rate was a key secondary endpoint. Other efficacy endpoints included progression-free survival, overall survival, overall response rate and duration of response.

About Breyanzi

Breyanzi is a CD19-directed CAR T cell therapy with a 4-1BB costimulatory domain, which enhances the expansion and persistence of the CAR T cells. Breyanzi is approved by the U.S. Food and Drug Administration (FDA) for the treatment of adult patients with large B-cell lymphoma (LBCL), including diffuse large B-cell lymphoma (DLBCL) not otherwise specified (including DLBCL arising from indolent lymphoma), high-grade B-cell lymphoma, primary mediastinal LBCL, and follicular lymphoma grade 3B who have refractory disease to first-line chemoimmunotherapy or relapse within 12 months of first-line chemoimmunotherapy, or refractory disease to first-line chemoimmunotherapy or relapse after first-line chemoimmunotherapy and are not eligible for hematopoietic stem cell transplant due to comorbidities or age, or relapsed or refractory disease after two or more lines of systemic therapy. Breyanzi is not indicated for the treatment of patients with primary central nervous system lymphoma. Please see the Important Safety Information section below, including Boxed WARNINGS for Breyanzi regarding cytokine release syndrome and neurotoxicity.

Breyanzi is also approved in Japan for the second-line treatment of relapsed or refractory LBCL, and in Japan, Europe, Switzerland and Canada for relapsed or refractory LBCL after two or more lines of systemic therapy. 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 lymphomas and leukemia.
