BMS Breyanzi ‘Deep and Durable Efficacy’
Bristol Myers Squibb says its Breyanzi (lisocabtagene maraleucel) showed “deep and durable efficacy” in the Phase 1/2 TRANSCEND CLL 004 study of adults with relapsed or refractory lymphocytic leukemia or small lymphocytic lymphoma. A company statement says Breyanzi delivered statistically significant complete response rates, the primary endpoint, in 18.4% of patients in the primary efficacy analysis. Among patients who achieved a complete response, it says, no disease progression or deaths were observed, with the median duration of response not reached.
Breyanzi is described as CD-19 directed CAR T cell therapy with a 4-1BB costimulatory domain. It is approved by FDA to treat large B-cell lymphoma, including certain patients with diffuse large B-cell lymphoma. It is not indicated to treat patients with primary central nervous system lymphoma.
