Shares of Provention Bio Inc. (NASDAQ:PRVB) closed March 13 at $24.10, up $17.40, or 259%, after Wall Street learned that collaborator Sanofi SA intends to acquire the firm for $25 per share in cash, which works out to an equity value of about $2.9 billion. The transaction brings Paris-based Sanofi the type 1 diabetes (T1D) therapy Tzield (teplizumab-mzwv), approved by the U.S. FDA in 2022 as the first and only therapy to delay the onset of stage 3 disease in adults and in pediatric patients ages 8 and older with T1D that has reached stage 2.
Provention Bio Inc. scored approval from the U.S. FDA of the BLA for Tzield (teplizumab-mzwv), an intravenously given, anti-CD3-directed antibody, as the first and only immunomodulatory treatment to delay the onset of stage 3 type 1 diabetes (T1D) in adult and pediatric patients ages 8 and older with stage 2 T1D.
Despite an FDA advisory committee’s narrow ruling that Provention Bio Inc.’s teplizumab has benefits that outweigh the risks in treating diabetes, the agency sent the company a complete response letter (CRL) regarding the diabetes therapy’s priority BLA. The CRL came the evening of July 2, Provention said, the PDUFA date that had been set months before.
The FDA’s Endocrinologic and Metabolic Drugs Advisory Committee (EMDAC) voted 10-7 May 27 that the benefits of Provention Bio Inc.’s teplizumab outweighed its risks, but the vote was not a ringing endorsement of the anti-CD3 monoclonal antibody biologic that could be the first disease-modifying treatment for people at risk of developing type 1 diabetes (T1D).
Provention Bio Inc.’s diabetes candidate, teplizumab, is heading into a May 27 advisory committee meeting with a skinnier label than originally planned, which could signal a smoother path to approval. The positive briefing document the FDA put out Tuesday also suggested an approval path for what could be the first disease-modifying treatment available for type 1 diabetes (T1D).
The FDA told Provention Bio Inc. that its BLA under priority review for teplizumab needs some work but the May 27 advisory committee meeting to discuss the application in full is still on the calendar.
Anti-drug antibodies noted in the phase Ib portion of the PREVAIL study in lupus drew queries for Oldwick, N.J.-based Provention Bio Inc. during a conference call related to earnings, but analysts seemed more interested in the company’s later-stage push in type 1 diabetes (T1D).
