Hansa Biopharma Enters Preclinical Research Collaboration With Argenx

Hansa Biopharma AB "Hansa", a pioneer in enzyme technology for rare immunological conditions, announced that they have entered into a preclinical research collaboration agreement with argenx BV to evaluate the therapeutic potential of combining the two companies' IgG-modulating technologies.

The preclinical research collaboration is set up to explore the potential of combining imlifidase, Hansa's IgG antibody-cleaving enzyme, and efgartigimod, argenx's FcRn antagonist, which are both in development for indications known to be driven by disease-causing IgGs. A combination of imlifidase and efgartigimod could potentially be used in both the acute and chronic setting of autoimmune diseases and transplantation.

Under the preclinical research collaboration agreement, both parties will contribute equally in terms of resource allocation and will share all intellectual property and data developed through the collaboration. Both parties will maintain exclusive rights to their respective technologies and products.

This is information that Hansa Biopharma AB is obliged to make public pursuant to the EU Market Abuse Regulation. The information was submitted for publication, through the agency of the contact person set out below, at 20:00 CET on March 29 2021.
