US FDA and EMA Accept Applications for Ozanimod for the Treatment of Relapsing Forms of Multiple Sclerosis

Celgene Corporation (NASDAQ:CELG) today announced that the U.S. Food and Drug Administration (FDA) has accepted for review the New Drug Application for ozanimod for the treatment of people with relapsing forms of multiple sclerosis (RMS) in the United States. The European Medicines Agency (EMA) also accepted for review the Marketing Authorization Application for ozanimod for the treatment of adults with relapsing-remitting multiple sclerosis (RRMS) in the European Union. Ozanimod is an oral, sphingosine 1-phosphate (S1P) receptor modulator that binds with high affinity selectively to S1P subtypes 1 (S1P₁) and 5 (S1P₅). Under the Prescription Drug User Fee Act, the FDA has set its action date as March 25, 2020. A regulatory decision from the EMA is expected in the first half of 2020.

Both applications are based primarily on ozanimod data from the SUNBEAM and RADIANCE Part B phase 3, multicenter, randomized, double-blind, double-dummy, active-controlled trials.

“The U.S. Food and Drug Administration and European Medicines Agency acceptances of our applications represent a crucial step forward in our efforts to bring ozanimod to people with multiple sclerosis,” said Jay Backstrom, M.D., Chief Medical Officer for Celgene. “We believe that ozanimod has the potential to be an important option early in the treatment of relapsing forms of MS and a best-in-class S1P receptor modulator.”

Ozanimod is an investigational compound that is not approved for any use in any country.

About SUNBEAM

SUNBEAM is a pivotal, phase 3, multicenter, randomized, double-blind, double-dummy, active-controlled trial evaluating the efficacy, safety and tolerability of two doses of oral ozanimod (0.92 mg and 0.46 mg, equivalent to 1 mg and 0.5 mg ozanimod HCI respectively) against weekly intramuscular interferon beta-1a (Avonex) for at least a 12-month treatment period. The study included 1,346 people living with RMS across 152 sites in 20 countries.

The primary endpoint of the trial was annualized relapse rates (ARR) during the treatment period. The secondary MRI endpoints included the number of new or enlarging hyperintense T2-weighted brain MRI lesions over 12 months, number of gadolinium-enhanced brain MRI lesions at month 12 and percent change from baseline in whole brain volume at month 12. Cortical grey and thalamic volume changes were also prospectively assessed versus active comparator.
