About Us

Encycle Therapeutics is a Toronto-based biotech company exploiting a unique platform technology that enables the rapid synthesis of drug-like macrocycles or membrane-permeable nacellins. Nacellins have enormous potential to target intracellular protein-protein interactions, which are largely intractable to small molecule and biologic modulation, and can represent cheaper, oral equivalents to existing biologics (e.g., monoclonal antibodies). Encycle has collaborated with several pharmaceutical companies to complete a screening library of nacellins, many of which are cell-permeable and possess other drug-like properties. The company is also pursuing independent development of nacellins against integrin alpha-4-beta-7 (IBD) and SMURF2 (fibrosis); its lead program seeks to develop orally bioavailable inhibitors of integrin alpha-4-beta-7, which are safer and less immunogenic than marketed and investigational biologics targeting the same protein.
