Ampersand Biomedicines Acquires AbCheck to Accelerate Platform and Product Development

Acquisition amplifies Ampersand’s in-house capabilities to generate AND-Body™ Therapeutics - programmed biologics across a broad range of diseases

BOSTON, Mass., January 3, 2024 – Ampersand Biomedicines, a multi-product platform company developing smarter medicines that act specifically at the site of disease and nowhere else, today announced the acquisition of AbCheck s.r.o., a technology company with a suite of antibody discovery technologies for challenging targets and a wholly-owned subsidiary of Affimed GmbH. The addition of AbCheck’s broad discovery platform and deep expertise in antibody generation and optimization will enable cost-effective and strategic acceleration of Ampersand’s Address, Navigate, Determine (AND)™ Platform.  

“We’ve made significant advances building our AND Platform, which combines powerful computational tools, robust screening approaches integrated with sophisticated protein engineering, and pharmacological evaluation capabilities to develop therapies that work precisely where needed and nowhere else,” said Jason Gardner, D. Phil., CEO of Ampersand Biomedicines and Flagship Pioneering CEO-Partner. “This acquisition will boost the AND Platform and enhance Ampersand’s ability to generate multiple AND-Body™ Therapeutics in parallel. I look forward to seamlessly integrating AbCheck’s broad antibody discovery capabilities and experienced team as one organization and together building a pipeline of drug candidates that have efficacy, safety, and tolerability for Ampersand and in partnership with companies in the Flagship ecosystem.”

AbCheck is a cutting-edge antibody discovery company with a platform of technologies that have successfully delivered against many targets. Over the last 15 years, AbCheck has validated its platform through more than 45 partnerships with biopharma companies and produced multiple clinical candidates. Through the acquisition, AbCheck will become a wholly-owned and independent unit of Ampersand.

“We’re proud of having built one of the leading antibody discovery and optimization platforms, with a highly successful track record,” commented Volker Lang, Ph.D., Managing Director of AbCheck. “We’re thrilled to join Ampersand and further our potential to discover and optimize novel antibodies against challenging disease targets through AND-body medicines.”
