FDA Accepts NDA for Sublingual Form of ALS Drug

FDA has accepted for review a Biohaven Pharmaceutical Holding Co. 505(b)(2) NDA for BHV-0223, an investigational sublingual form of riluzole for treating patients with amyotrophic lateral sclerosis (ALS). Biohaven previously announced that the agency granted orphan drug designation for BHV-0223 in ALS. The company says BHV-0223 is a novel, lower dose formulation of riluzole, which is the only FDA-approved treatment to extend tracheostomy-free survival in people living with ALS.

 

The submission is supported by data from multiple studies and clinical trials evaluating the bioequivalence of BHV-0223 to riluzole oral tablets (Rilutek), as well as the safety and tolerability of BHV-0223. Data showed that sublingual administration of BHV-0223 (40 mg) achieved similar blood exposures to orally ingested Rilutek (50 mg), the company says.
