Biohaven's Nurtec (riluzole) 505(b)2 Application for Amyotrophic Lateral Sclerosis Affected by Issues Related to Apotex Plant: Complete Response Letter (CRL) Received From FDA Related to Isolated ...

NEW HAVEN, Conn., July 19, 2019 /PRNewswire/ -- Biohaven Pharmaceutical Holding Company Ltd. (NYSE: BHVN), a clinical-stage biopharmaceutical company with a portfolio of innovative, late-stage product candidates targeting neurological and neuropsychiatric diseases, today announced that it has received a Complete Response Letter (CRL) from the FDA for the 505(b)2 application seeking approval for NURTEC™ (riluzole) for ALS.

The sole issue identified in the CRL relates to an FDA concern regarding the use of an active pharmaceutical ingredient (API) that was manufactured by Apotex Pharmachem India Private Limited ("Apotex") between 2014 to 2016 and used in the drug product supplies for the bioequivalence study in 2017.  Of note, concerns with Apotex manufacturing recently led to the withdrawal of 31 Apotex drug products from the US market last Wednesday, July 10th 2019 (  

In the CRL, the FDA stated that it provided recommendations to Apotex regarding the information that would be needed to qualify previous API batches manufactured at Apotex during the time period in question. Apotex did not provide Biohaven with notice of the FDA communication, either during the course of its bioequivalence trial or during the submission of its 505(b)2 application for Nurtec (riluzole). Biohaven has been subsequently informed by the manufacturer that they had an exemption from the FDA to supply riluzole to the U.S. market during that time period. Today, Biohaven has been in contact with the FDA's CMC group and Apotex to resolve the matter and Biohaven has already submitted additional information to the FDA regarding this issue.

Biohaven notes that the API for commercial supply of Nurtec (riluzole) is currently sourced from another supplier, with whom no CMC issues have been identified.  Further, the FDA did not cite any other concerns in their CRL regarding Nurtec (riluzole).  Biohaven will be working with the FDA to develop a timely path forward. While timelines are developed to resolve this matter, Biohaven will re-deploy the associated funds for Nurtec (riluzole) commercialization to other commercial needs of the organization.

Robert Berman, M.D., Biohaven CMO and Nurtec (riluzole) Development Lead, commented, "We are doing everything possible to work with the FDA and the API manufacturer to resolve this matter, which we believe to be more technical in nature.  We believe that the quality issues surrounding the Apotex manufacturing facility do not affect the conclusions of our bioequivalence study, but will work collaboratively with the FDA to resolve this matter as quickly as possible." 

John Tilton, Chief Commercial Officer for Rare and Orphan Disease, added, "Biohaven would like to thank the ALS community, including people and caregivers living with ALS, for their participation in our BHV-0223 clinical trials and early access program." Mr. Tilton continued, "Biohaven remains committed to addressing the unmet needs of patients with ALS on multiple fronts including other novel pipeline assets that we will consider pursuing in ALS."

About Nurtec (riluzole)

Nurtec (riluzole) (BHV-0223) is a sublingually administered tablet. While riluzole is FDA-approved for ALS, existing formulations consist only of an oral tablet taken with water or an oral suspension (thickened liquid). Nurtec (riluzole) is designed to be placed under the tongue where it dissolves in seconds and is absorbed by the vasculature, thereby eliminating the need for swallowing.

NURTEC is a trademark of Biohaven Pharmaceutical Holding Company Ltd.
