Regeneron Provides Update on Biologics License Application for Odronextamab

TARRYTOWN, N.Y., March 25, 2024 (GLOBE NEWSWIRE) -- Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) today announced that the U.S. Food and Drug Administration (FDA) has issued Complete Response Letters (CRLs) for the Biologics License Application (BLA) for odronextamab in relapsed/refractory (R/R) follicular lymphoma (FL) and in R/R diffuse large B-cell lymphoma (DLBCL), each after two or more lines of systemic therapy. The only approvability issue is related to the enrollment status of the confirmatory trials. The CRLs – one for R/R FL and one for R/R DLBCL – did not identify any approvability issues with the odronextamab clinical efficacy or safety, trial design, labeling or manufacturing.

Regeneron has been actively enrolling patients in multiple Phase 3 trials for odronextamab as part of the OLYMPIA program – one of the largest clinical programs in lymphoma. As the OLYMPIA program is intended to change the treatment paradigm of several B-cell non-Hodgkin lymphoma subtypes – including in earlier lines of therapy – in agreeing to the program, the FDA required that the trials include both dose-finding and confirmatory portions. Enrollment in the dose-finding portion has begun, but the CRLs indicate that the confirmatory portions of these trials should be underway and that the timelines to completion be agreed prior to resubmission. Regeneron is committed to working closely with the FDA and investigators to bring odronextamab to patients with R/R FL and R/R DLBCL as quickly as possible. Regeneron plans on sharing updates on enrollment and regulatory timelines later this year.

Regulatory review of odronextamab remains ongoing by the European Medicines Agency (EMA) for the treatment of R/R DLBCL and R/R FL. In the European Union, odronextamab was granted Orphan Drug Designation in DLBCL and FL.

The potential use of odronextamab in R/R DLBCL and R/R FL is currently under clinical development and has not been approved by any regulatory authority.
