STUART, Fla., July 22, 2022 /PRNewswire/ -- Stuart Therapeutics, Inc. (Stuart), a clinical stage company developing advanced ophthalmic therapeutics, announced today that the United States Patent and Trademark office has issued a Notice of Allowance in each of two patent applications associated with the company's clinical product candidates, including ST-100, Stuart's drug candidate for the treatment of dry eye disease (DED) which recently completed a successful Phase 2 trial. Specifically, the company has secured allowances on the following U.S. patent applications which are exclusively licensed to Stuart Therapeutics by the owner of the applications, Stuart's affiliate Sustain Holdings, LLC: Stuart, Florida Stuart Therapeutics Announces Important Additions to the Company's Intellectual Property Portfolio Tweet this U.S. Application No. 16/839,987, which claims compositions of matter comprising Stuart's proprietary Collagen Mimetic Peptide (CMP) compounds, including the ST-100 formulation. The claims of this patent, once issued, are expected to encompass the currently planned commercial version of the company's ST-100 product candidate. This allowed patent application is a continuation of U.S. Patent No. 10,632,168, also exclusively licensed to Stuart, which claims the use of CMP-containing formulations such as ST-100 in treating a variety of ocular diseases, disorders or wounds including dry eye disease and glaucoma. U.S. Application No. 17/749,729, also a continuation of U.S. Patent No. 10,632,168, which claims the use of CMP-containing formulations such as ST-100 in treating a variety of ocular diseases, disorders or wounds including cataracts, corneal ulcerations, scleritis, keratoconus and post-operative eye wounds. The company expects to pursue certain of these indications in forthcoming clinical trials. These allowances are expected to result in the issuance of two new patents within the next 6-8 weeks, upon the completion of certain administrative requirements. The grant of these patents further strengthens Stuart's U.S. and international patent portfolio for its PolyColTM ( PolyCol) platform of synthesized CMPs and their use in potentially treating, preventing and/or diagnosing a variety of diseases and disorders in humans and veterinary animals. "These new patent allowances, combined with previous patent awards in the U.S. and abroad for various methods of use including treating ocular surface disease and glaucoma, means that Stuart's PolyCol CMP platform, and particularly its ST-100 product candidate, has broad and strong intellectual property protection, and will be very important as we continue to develop and ultimately seek approval for commercialization of ST-100 and other CMP drug candidates" said Eric Schlumpf, President & CEO of Stuart. In pre-clinical animal studies and in human clinical trials, Stuart's PolyCol CMPs have been shown to repair damaged collagen triple helices and restore epithelial and neuronal cells and cellular processes that rely on native collagen as a part of the associated Extracellular Matrix (ECM) for promotion and maintenance of normal cell and tissue structure and function. The company's CMPs are believed to work by reconstituting the collagen triple helix in areas in vivo where it has been disrupted by disease or wounding, thereby causing a recovery of the normal cell signaling and structural roles that collagen plays in tissue homeostasis. ST-100, Stuart's first drug candidate, has demonstrated in pre-clinical animal testing that it provides rapid repair of damaged corneal epithelial and sub-epithelial tissues in the eye and reduction in the production of pro-inflammatory mediators, coupled with restoration of corneal nerve structures, making it an ideal therapeutic candidate for treating DED and other ocular surface indications. Applied in a drop formulation, ST-100 has also demonstrated that it can lead to rapid improvement in the symptoms and signs of DED in humans, as seen in Stuart's Phase 2 clinical trial. Stuart believes that ST-100 should be broadly applicable to the estimated 30 million sufferers of DED in the United States, working via a direct reparative approach to alleviating painful eye surface damage that is a hallmark of DED. About Stuart Therapeutics: Stuart Therapeutics is a clinical stage pharmaceutical company focused on the development of PolyCol, a collagen mimetic peptide therapeutic platform. The company is developing a variety of anterior and posterior segment ophthalmologic applications based on the PolyCol technology.

STUART, Fla., July 18, 2022 /PRNewswire/ -- Stuart Therapeutics, Inc. (Stuart), a clinical stage company headquartered in Stuart, Florida that is developing advanced ophthalmic therapeutics, announced today the results of its Type C Guidance meeting with the U.S. Food and Drug Administration (FDA) regarding the continued development plan for ST-100, Stuart's first drug candidate for the treatment of Dry Eye Disease (DED) in humans. Stuart provided the FDA with the results of the ST-100 Phase 2 clinical trial, completed late last year, and asked for the agency's guidance relating to the company's proposed next steps, including a Phase 3 clinical trial and associated endpoints for ST-100. The FDA provided Stuart with its acceptance of the company's plan to conduct a Phase 3 trial for ST-100, along with approval of the proposed endpoints which include a single primary endpoint (Schirmer's Responder Rate) and a series of secondary endpoints proposed by the company. In addition, the FDA accepted the overall development plan proposed by Stuart. Stuart, Florida Stuart Therapeutics, Inc. announces results of its Type C meeting with FDA Tweet this Based on the FDA's positive response to Stuart's Type C meeting submittal, the company anticipates proceeding with a Phase 3 clinical trial on ST-100 in early 2023. "The FDA feedback we received is welcome and allows us to proceed as planned to a Phase 3 clinical trial for ST-100 in the first quarter of 2023. The clarity of the results we achieved in a small population (160 patients) Phase 2 trial late last year puts us in a strong position. The rapid, systematic Schirmer's test results, achieved in 28 days, coupled with strong symptom relief at day 14, position ST-100 as a potential leader in the treatment of ocular surface disease," said Bob Baratta, MD, Chairman and Chief Medical Officer of Stuart. ST-100 is an eyedrop formulation that is based on Stuart's patented Collagen Mimetic Peptide platform, PolyCol™ ( PolyCol). Pre-clinical animal testing has demonstrated that ST-100 provides rapid repair of damaged corneal epithelial and sub-epithelial tissues in the eye, coupled with restoration and protection of corneal nerve structures, making it an ideal therapeutic candidate for DED and possibly for other ocular surface indications. Stuart believes that ST-100 should be broadly applicable to the estimated 30 million sufferers of dry eye disease in the United States, due to ST-100's apparent ability to alleviate painful eye surface damage that is a hallmark of DED. "The result of this meeting with the FDA is that Stuart can move quickly into a larger (300+ patients) Phase 3 clinical trial to further demonstrate the safety and efficacy of ST-100 for the treatment of dry eye disease. This outcome represents continued confirmation of the success of our strategy to move ST-100 through the clinical trial process, and we thank the Stuart development team and our outside partners and advisors for the part they played in bringing us to this point," said Eric Schlumpf, President & CEO of Stuart Therapeutics.
