Provention Bio Announces Teplizumab BLA for Delay or Prevention of Clinical T1D

Provention Bio announced the Biologics License Application (BLA) for teplizumab for the delay or prevention of clinical type 1 diabetes (T1D) in at-risk individuals has been filed by the U.S. Food and Drug Administration (FDA). The FDA also granted Provention's request for Priority Review and assigned a user fee goal date of July 2, 2021, under the Prescription Drug User-Fee Act (PDUFA).

"The FDA's acceptance of our BLA represents a significant achievement for Provention Bio in our mission to deliver the first potential disease-modifying T1D therapy and drive a paradigm shift in how individuals at risk of developing the disease are treated," said Ashleigh Palmer, CEO and Co-Founder, Provention Bio. "We intend to work closely with the FDA to support their review while also preparing for a potential product launch in the third quarter of 2021."

In its acceptance letter, the FDA stated that it is currently planning to hold an advisory committee meeting, tentatively scheduled for May 27, 2021.

Priority Review is afforded to drugs that, if approved, would represent a significant improvement in the safety or effectiveness of the treatment, diagnosis, or prevention of a serious condition. Under the PDUFA, a Priority Review targets a review time of six months compared to a standard review time of ten months. The FDA previously granted teplizumab Breakthrough Therapy Designation.

Teplizumab is an investigational anti-CD3 monoclonal antibody (mAb) with a filed BLA under Priority Review by the FDA for the delay or prevention of clinical T1D in at-risk individuals. More than 800 patients have received teplizumab in multiple clinical studies involving more than 1,000 subjects. In previous studies of newly diagnosed patients, teplizumab consistently demonstrated the ability to preserve beta-cell function, a measure of endogenous insulin production, and correspondingly reduced the need for exogenous insulin use. Teplizumab has been granted Breakthrough Therapy Designation by the FDA and PRIME designation by the European Medicines Administration. Provention Bio has submitted a Biologic License Application (BLA) to the FDA for teplizumab for the delay or prevention of clinical type 1 diabetes in at-risk individuals. Provention is currently also evaluating teplizumab in patients with newly diagnosed insulin-dependent T1D (the Phase 3 PROTECT study).
