Encinitas, California--(Newsfile Corp. - February 13, 2025) - Kiora Pharmaceuticals, Inc. (NASDAQ: KPRX) today announced that the U.S. Patent and Trademark Office has issued a composition-of-matter patent (US-12209073-B2) on a specific crystalline form, or polymorph, of KIO-104. KIO-104 is a novel, non-steroidal anti-inflammatory, small molecule inhibitor of dihydroorotate dehydrogenase (DHODH). A Phase 2 clinical trial of KIO-104 for the treatment of retinal inflammation is expected to begin in the first half of 2025. This new patent is expected to extend protection of KIO-104 into 2043.
This newly issued patent, titled, Polymorphs of a Dihydroorotate Dehydrogenase (DHODH) Inhibitor, provides important and expanded intellectual property protection for KIO-104, specifically covering a critical and unique polymorph. This distinct crystalline form covered by the patent offers enhanced molecular stability and solubility, which are critical to optimize the manufacturing of the drug substance.
“Securing this patent issuance further extends and strengthens our existing IP position, which includes previously issued methods of use, drug delivery and formulation patents,” said Brian M. Strem, PhD, President & Chief Executive Officer of Kiora Pharmaceuticals. “The protection of this specific polymorph is crucial as it allows us to optimize production, stability and delivery in a proprietary way, which translates into enhanced opportunities and therapeutic potential of KIO-104.”
A multicenter Phase 2 clinical trial, the KLARITY study, will investigate KIO-104 in up to 28 patients with macular edema, a condition where inflammation causes a build-up of fluid behind part of the retina and can be associated with adverse vision changes. KIO-104, as a potent, locally delivered small molecule, could provide a needed alternative to steroids or systemic anti-inflammatory drugs.
