Novartis Plans BLA for Arzerra in MS
Novartis says that later this year it will file a BLA and seek other global approvals for its leukemia drug Arzerra (ofatumumab) and its use in treating relapsing forms of multiple sclerosis (MS). The submission will be based on just-announced data from the Phase III ASCLEPIOS I and II studies. In both head-to-head studies, ofatumumab demonstrated superiority over Sanofi’s Aubagio (teriflunomide) in patients with relapsing forms of multiple sclerosis (RMS), Novartis says. The studies compared monthly subcutaneous ofatumumab 20mg versus once daily oral Aubagio 14mg in adults with RMS.
“Both studies met the primary endpoints where ofatumumab showed a highly significant and clinically meaningful reduction in the number of confirmed relapses, evaluated as the annualized relapse rate,” Novartis says. “Key secondary endpoints of delaying time to confirmed disability progression were also met.”
Novartis says ofatumumab works by binding to the CD20 molecule on the B-cell surface and inducing potent B-cell lysis and depletion. Positive Phase IIb results in MS patients were presented in 2014 and showed a significant reduction in new brain lesions in the first 24 weeks after ofatumumab administration, it says. Novartis obtained rights for ofatumumab from Genmab 12/2015.
