About Circle Pharma, Inc.

Circle is developing a new paradigm for macrocycle drug discovery based on rational design and synthetic chemistry. Circle's technology facilitates the design and synthesis of intrinsically cell-permeable macrocycles that can address both intra- and extra-cellular therapeutic targets, and can be delivered by oral administration. Circle's macrocycle development platform is applicable across a wide range of serious diseases; the company is initially focusing its development efforts on intracellular protein-protein interactions that are key drivers in cancer. Its lead program targets cyclins A and E, which are part of the regulatory machinery that controls the progression of cells through the cell growth and division cycle. Inhibiting cyclins A and E has been shown to be synthetically lethal in cancers that carry mutations causing dysregulation of the Rb pathway.
