ImmunoPrecise Antibodies and ChemPartner Biologics Announce PolyTope® TATX-03 Antibody Cocktail Manufacturing Collaboration

IMMUNOPRECISE ANTIBODIES LTD. (“IPA” or the “Company”) (NASDAQ: IPA) (TSX VENTURE: IPA) and ChemPartner Biologics Co. Ltd. (“ChemPartner”) today announced their global antibody manufacturing collaboration under which ChemPartner will manufacture and supply to IPA’s specifications IPA’s proprietary PolyTope® TATX-03 Therapy, a rationally designed four monoclonal antibody cocktail developed for use in human clinical trial for the potential prevention and treatment of infection with current and future variants of SARS-CoV-2. The goal of this collaboration is to secure the ability to quickly develop and manufacture in parallel the individual cocktail antibodies in IPA’s PolyTope TATX-03 up to large scale required for use in clinical development and using ChemPartner’s state-of-the-art manufacturing facilities, with the potential for additional capacity to manufacture ‘plug-and-play' antibodies addressing novel variants of concern in the event this is desired.

“In light of the recent events as it pertains to concerns about vaccines and therapeutic antibodies losing efficacy against novel variants of concern, we believe that, if the preclinical data that we have to date is confirmed through human clinical studies, IPA is in a strong position to potentially address a worldwide need for alternative SARS-CoV-2 therapies using our Polytope cocktail. Our relationship with ChemPartner is one further step in that direction. Based on the work we have done to date with ChemPartner, and the positive interactions between our two teams, we believe that ChemPartner has the experience and global capabilities to meet our currently anticipated manufacturing needs for PolyTope TATX-03 cocktail,” stated Dr. Jennifer Bath, President and Chief Executive Officer at IPA.

“We are impressed by the innovative approaches of ImmunoPrecise Antibodies and excited to help advance their TATX-03 PolyTope® antibody cocktail program against SARS-CoV-2,” said Livia Legg, Chief Commercial Officer at ChemPartner. “ChemPartner Biologics is strategically positioned to join forces in the battle against Covid-19 disease by utilizing our extensive capabilities and expertise in developing, scaling and manufacturing of complex biologics.”
