Genmab BLA OK’d for Large B-cell Lymphoma

Share

FDA has granted Genmab an accelerated approval for its BLA for Epkinly (epcoritamab-bysp) injection for treating adult patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL) and high-grade B‑cell lymphoma after two or more lines of systemic therapy. DLBCLs are the most common type of non-Hodgkin lymphoma cancer and are associated with rapidly growing tumors in the lymph nodes, spleen, liver, bone marrow, or other tissues and organs, the agency says. Epkinkly is intended to be administered subcutaneously in 28-day cycles until disease progression or unacceptable toxicity, it adds.

Approval was based on data from a study entitled EPCORE NHL-1 (NCT03625037) that involved 148 patients with relapsed or refractory DLBCL that measured overall response rate (ORR). FDA says the study showed that the ORR was 61% with 38% of patients achieving complete responses. “With a median follow-up of 9.8 months among responders, the estimated median duration of response was 15.6 months,” it says.

FDA notes that the prescribing information includes a Boxed Warning for serious or life-threatening cytokine release syndrome (CRS) and life-threatening or fatal immune effector cell-associated neurotoxicity syndrome (ICANS). “Among the 157 patients with relapsed or refractory large B-cell lymphoma who received Epkinly at the recommended dose, CRS occurred in 51% of patients, ICANS in 6%, and serious infections in 15%,” the agemcy says.
