Antharis Therapeutics Acquires Cassyni Biopharma and Their Portfolio of Assets


SAN DIEGO—Antharis Therapeutics Inc., a biopharmaceutical company developing a leading portfolio of oncology and neurology related immunotherapeutics, today announced the completion and integration of their acquisition of Cassyni Biopharma. This acquisition brings several exciting new assets to Antharis’s pipeline. The deal marks Antharis’s rapid growth as a company to sit at the leading edge of biotechnology companies generating high-potential biologic assets for the treatment of significant diseases in multiple therapeutic classes.

“Acquiring Cassyni increases our company’s pipeline, expands Antharis Therapeutics into new therapeutic areas to better serve future patients, and is a very exciting step forward as Antharis moves into pre-IND work this year,” said Raphael Ribeiro-Pinaud, CEO of Antharis Therapeutics.

Antharis leverages a unique platform for the discovery, characterization, and validation of monoclonal antibody assets across the oncology and neurology therapeutic areas. The company’s unique view of immunotherapy and highly specialized platform have delivered successfully validated in vivo assets at a significantly higher rate than the industry norm. This has allowed Antharis to grow one of the largest preclinical portfolios in the industry and supported the company’s recent successful Series A fundraising. Antharis will begin pre-IND work on a selection of their assets this year.
