AGC Biologics to Commercial Manufacture Provention Bio Diabetes Therapy

The biopharma CDMO Seattle site continues mammalian cell culture work on this new T1D treatment, the first and only treatment approved to delay the onset of Stage 3 type 1 diabetes (T1D) in adult and pediatric patients aged 8 years and older with Stage 2 T1D.

AGC Biologics, a leading global Biopharmaceutical Contract Development and Manufacturing Organization (CDMO), today announced a new commercial manufacturing project at its Seattle protein biologics manufacturing site. The CDMO is producing TZIELD™ (teplizumab-mzwv), a new T1D treatment from Provention Bio, Inc. (Nasdaq: PRVB), a biopharmaceutical company focused on advancing the development of investigational therapies that may intercept and prevent debilitating and life-threatening immune-mediated diseases.

Provention Bio chose AGC Biologics to manufacture TZIELD after the CDMO helped guide the product through PPQ manufacturing and validation batches, and United States Food and Drug Administration (FDA) approval. More than 1.8 million Americans have T1D, an autoimmune disease caused by the destruction of beta cells. TZIELD is the first and only immunomodulatory treatment that delays the onset of Stage 3 T1D in adult and pediatric patients aged 8 years and older. Patients who progress to Stage 3 T1D will eventually require insulin injections for life.

"The multi-year process of shepherding a new therapy from clinical research to commercial launch requires the collaboration of multiple partners, and we are grateful for the ongoing strategic collaboration of AGC Biologics as we begin to deliver TZIELD to patients," said Provention Bio CEO Ashleigh Palmer. "This is an important milestone for the Type 1 Diabetes community, and we hope the launch of this therapy can truly make an impact on patients and families seeking innovative treatments for the delay of Stage 3 T1D."

AGC Biologics runs multiple mammalian cGMP manufacturing lines and a variety of scales at its Seattle facility. The campus serves as a center of excellence for formulation and employs the latest fed-batch and perfusion manufacturing processes and houses a new microbial-based manufacturing line system. The AGC Biologics Seattle campus has produced biologics products for 30 years and has a long history of successful inspections by the FDA and commercial production.

"Congratulations to Provention Bio on this game-changing achievement for T1D patients," said Kevin Ingham, General Manager of AGC Biologics' Seattle site. "We at AGC Biologics are proud to have helped develop this innovative new medicine and to be manufacturing it for commercial distribution. This achievement demonstrates our Seattle site's increasing track record in commercial manufacturing, which is aligned with AGC Biologic's purpose of bringing hope to life."
