Stuart Therapeutics and PolyCol

Stuart Therapeutics’ PolyCol™ platform of synthesized therapeutic polypeptides targets and heals specific areas of collagen damage that are implicated in chronic diseases of the eye. In several chronic ophthalmic indications, disease processes cause cellular release of enzymes called matrix metalloproteinases (MMPs) that degrade and remodel collagen proteins. One specific area of degradation is in helical collagen structures (found in all collagen types). These helical structures are important domains that are involved in intra- and intercellular signaling in healthy tissue. When acted on by MMPs, the resulting disruption in these helical structures diminishes their activity as signaling proteins, leading to a cycle of inflammation and further damage. Healthy collagen structures are required for full and healthy recovery of the affected tissues. Normally, collagen is replaced quite slowly compared to other tissues in the body.  As people age, the body’s ability to produce replacement collagen is reduced, thus leading to chronic disease. PolyCol CMPs are structured as a single strand of amino acids, and are mimics of sequences found in normal, healthy helical collagen domains. These CMPs are specifically designed to bind or intercalate into the key damaged areas in the collagen-containing matrix, restoring cell signaling and the structural role that collagen plays in healthy tissues. Treatment with CMPs works quickly, and results in the rapid restoration of tissue health and concomitant reduction in inflammation. PolyCol is being developed for several common disease indications in ophthalmology, including Dry Eye Disease, Glaucoma, Diabetic Retinopathy, Recurrent Corneal Erosion, and Myopia.

Our lead product candidate, ST-100, is being developed for the signs and symptoms of dry eye disease (DED).  Stuart’s ST-100 is a targeted tissue reparative technology, restoring the helical collagen structures to their primary structural and cell signaling ligand binding site role.  This results in an extremely robust recovery of corneal nerve function, and the ocular surface, including goblet cells and corneal epithelium.

Our Science

Stuart Therapeutics will begin its Phase 3 clinical trial for its first drug candidate, ST-100 (vezocolmitide) for Dry Eye Disease in December of 2023. The company has also completed extensive in vitro and in vivo research to profile the multiple amino acid sequence variants of the PolyCol platform, including their impact on accelerating tissue healing and reduction of inflammation in other important ophthalmic indications.
