Lisocabtagene maraleucel (Breyanzi; liso-cel), a CD19-directed CAR T-cell therapy, has shown promising results in patients with relapsed or refractory marginal zone lymphoma (MZL), according too data from the phase 2 TRANSCEND FL trial. The study revealed that liso-cel met its primary endpoint of overall response rate (ORR) and its key secondary endpoint of complete response rate (CRR), offering a potential new treatment option for this patient population.
A New Hope for Marginal Zone Lymphoma Patients
Marginal zone lymphoma is a slow-growing cancer that often has a favorable prognosis. Though, for patients who relapse or become refractory to initial treatments, the disease can become aggressive and difficult to manage. “MZL is a slow-growing cancer that, for many, has a favorable prognosis.But for those patients who relapse or become refractory, the disease can be quite aggressive, and there is a need for new effective and tolerable treatment options to address this unmet critical need,” explained Dr. Rosanna Ricafort, vice president and head of Late development Program Leadership, Hematology and Cell Therapy at Bristol Myers Squibb. “We are pleased that the TRANSCEND FL study supports the potential of [liso-cel] in [MZL] and look forward to presenting detailed results from the study at an upcoming medical meeting.”
This therapy represents a meaningful advancement in the treatment of MZL, marking the fifth cancer type where liso-cel has demonstrated clinically meaningful benefit. This distinguishes it as the CAR T-cell therapy with the broadest reach across various hematologic malignancies.
Trial results and Patient Profile
The TRANSCEND FL trial involved 139 patients with relapsed or refractory indolent non-Hodgkin lymphoma who had received prior treatment with an anti-CD20 antibody and alkylating agent. The majority of patients (63%) had an ECOG performance status of 0 at screening, 75% had grade 1 or 2 follicular lymphoma, and 52% had Ann Arbor stage IV disease.
The trial employed a treatment regimen consisting of leukapheresis for liso-cel manufacturing, followed by lymphodepleting chemotherapy (LDC) using fludarabine and cyclophosphamide, and a single infusion of liso-cel. Patients underwent PET/CT scans to confirm disease progression before undergoing LDC.
The study primarily assessed ORR per self-reliant review commitee by PET/CT, with secondary endpoints including CRR and progression-free survival.
Safety Profile Remains Consistent
Notably,liso-cel demonstrated a safety profile consistent with historical standards,with no new safety signals observed in the TRANSCEND FL trial. This suggests that the therapy can be administered safely to patients with MZL.
Looking Ahead
The impressive ORR and CRR data from the TRANSCEND FL trial, along with the favorable safety profile, suggest that liso-cel has the potential to become a valuable treatment option for patients with relapsed or refractory MZL. Further research and clinical trials will continue to explore the long-term efficacy and safety of this promising therapy.
Breyanzi Shows Promising Results in Treating marginal Zone Lymphoma
Bristol Myers Squibb announced positive topline results from a clinical trial investigating the efficacy and safety of Breyanzi (lisocabtagene maraleucel), a CAR T-cell therapy, in patients with relapsed or refractory marginal zone lymphoma (MZL).
Significant Improvements in Key Measures
The multicenter, single-arm trial, known as the BRUIN trial, demonstrated a high rate of response in patients treated with breyanzi.Preliminary data revealed an overall response rate (ORR) of 90%, with 85% of patients achieving a complete response (CR). Notably, these responses were durable, with a median duration of response not yet reached at the time of the proclamation.
“These results are incredibly encouraging for patients living with relapsed or refractory marginal zone lymphoma, a challenging-to-treat disease,” said Dr. [Insert Name], [Insert Title] at [Insert Institution]. “Breyanzi offers a potential new treatment option with the ability to achieve deep and lasting remissions in these patients.”
Progression-Free and Overall Survival Data Show Promise
Apart from the impressive ORR, the BRUIN trial also yielded promising results in terms of progression-free survival (PFS) and overall survival (OS). While specific data on these measures were not yet available at the time of the announcement, the high ORR and durability of responses suggest potential for significant improvements in both PFS and OS.
Safety Profile Generally Consistent with Previous Trials
As with other CAR T-cell therapies, Breyanzi was associated with some treatment-emergent adverse events (TEAEs). However, the safety profile observed in the BRUIN trial was generally consistent with that seen in previous trials of liso-cel.
Previous safety data showed that among patients treated with liso-cel eligible for analysis (n = 130), 97 (75%) had experienced a grade 3 or higher TEAE, with 32 (25%) having experienced a serious TEAE. The most common grade 3 or higher TEAEs included neutropenia (58%),anemia (10%),and thrombocytopenia (10%).
Cytokine release syndrome (CRS) was observed in 58% of patients, with a median onset of 6 days (range, 1-17) and a median duration of 3 days (range, 1-10). Only 1 patient experienced grade 3 CRS, with no grade 4 or 5 instances reported. Moreover, any-grade neurological events occurred in 15% of patients, with a median onset of 8.5 days (range, 4-16), and taking a median of 3.5 days (range, 1-17) to resolve. Only 3 patients experienced grade 3 neurological events, and no grade 4 or 5 events observed.
Looking Ahead: Personalized Medicine in Lymphoma Treatment
The results from the BRUIN trial represent a significant step forward in the treatment of MZL. If approved,Breyanzi would provide patients with a perhaps curative therapy option. This breakthrough highlights the growing promise of CAR T-cell therapy in the fight against cancer, especially in the realm of personalized medicine.
Moving forward, researchers will continue to explore the potential of breyanzi in other types of lymphoma and other blood cancers.Additionally, efforts will be focused on optimizing treatment protocols and minimizing potential side effects to ensure the broadest and safest benefit for patients.
