XERS: Collab w/ REGN on XeriJect & Lic. Option

Xeris Biopharma Holdings, Inc. (Nasdaq: XERS), a growth-oriented biopharmaceutical company committed to improving patient lives by developing and commercializing innovative products across a range of therapeutic areas, today announced that it has entered into a platform research evaluation collaboration and option agreement with Regeneron Pharmaceuticals, Inc. Under the terms of the agreement, Xeris will use its proprietary drug-formulation platform, XeriJect™, to develop ultra-highly concentrated, ready-to-use, small volume subcutaneous injections of two undisclosed monoclonal antibodies (mAbs) developed by Regeneron. Xeris will receive an upfront payment and potential milestone payments for preclinical achievements. Regeneron has an option to commercially license the Xeris technology for such molecules and nominate additional molecules for reformulation and potential commercialization. Specific financial terms of the agreement were not disclosed.

“We are excited to be working with Regeneron on a platform collaboration basis, which builds on our prior feasibility studies and reflects the significant progress and investment we have been making into the development of XeriJect™,” said Paul R. Edick, Chairman and CEO of Xeris Biopharma. “Through our novel drug-formulation platform, we aim to provide our biologic development collaborators with the competitive advantage of delivering a significantly improved patient and provider experience through stable, ready-to-use, ultra-highly concentrated, small-volume subcutaneous injection formulations. This agreement with Regeneron is another in a series of collaborations Xeris has recently undertaken with top pharmaceutical and biotechnology companies.”
