Pfizer Gets Expanded Approval for Adcentris
FDA has approved a Pfizer supplemental BLA for Adcetris (brentuximab vedotin) in combination with lenalidomide and rituximab for treating adult patients with relapsed or refractory large B-cell lymphoma (LBCL), including diffuse large B-cell lymphoma (DLBCL), including DLBCL arising from indolent lymphoma, or high-grade B-cell lymphoma, after two or more lines of systemic therapy who are not eligible for autologous hematopoietic stem cell transplantation or chimeric antigen receptor (CAR) T-cell therapy.
The approval is based on efficacy and safety data from the Phase 3 ECHELON-3 study, which “demonstrated a statistically significant and clinically meaningful improvement in overall survival (OS) in patients with relapsed/refractory DLBCL who received Adcetris in combination with lenalidomide and rituximab,” Pfizer says. Adcetris is currently approved for eight lymphoma indications.
The company says LBCL is a type of non-Hodgkin lymphoma that affects immune cells (B lymphocytes) that are crucial to the body’s immune system. DLBCL is the most common, aggressive and difficult-to-treat form of the disease, it notes.
