Parabilis Medicines Announces Strategic Collaboration with Regeneron Pharmaceuticals to Advance Novel Antibody-Helicon™ Conjugates Across Multiple Therapeutic Areas

The multi-target collaboration combines Parabilis’s novel Helicon™ peptide platform with Regeneron’s industry-leading antibody capabilities

Agreement provides for Parabilis to receive $125M from Regeneron, including a $50M upfront payment and a $75M equity commitment, with up to approximately $2.2B in additional potential milestone payments plus tiered royalties

Parabilis Medicines today announced a strategic research collaboration with Regeneron Pharmaceuticals, Inc. to discover and develop multiple therapeutic candidates based on Parabilis’s Helicon™ peptide platform, with a particular focus on Antibody-Helicon™ Conjugates (AHCs), a novel class of therapeutics designed to target challenging and historically “undruggable” targets.

Helicons are stabilized, cell-penetrant alpha-helical peptides designed to engage intracellular protein targets, including flat surfaces not well suited to traditional small molecule binding. The collaboration is designed to explore the use of Helicons both as stand-alone therapies and as part of AHCs.
