Insights
Kiora's new patent strengthens KIO-104's market exclusivity until 2043, significantly enhancing the company's ocular disease treatment portfolio.
Kiora Pharmaceuticals has secured a critical intellectual property victory with their newly granted US Patent No. 12,364,680 for KIO-104. This patent provides broad therapeutic coverage across multiple ocular conditions including inflammation, uveitis, age-related macular degeneration, and complications from refractive surgery. The patent's scope extends to various dosing schedules and formulation elements, creating multiple layers of protection.
The patent's extension of market exclusivity through 2043 represents approximately 18 years of protection, substantially longer than the typical patent life remaining after clinical development. This timing suggests Kiora has successfully employed strategic patent filing tactics to maximize KIO-104's commercial potential.
KIO-104's mechanism of action - inhibiting the mitochondrial enzyme DHODH to reduce T-cell replication and function - offers a differentiated approach compared to current standard treatments. The compound potentially addresses the limitations of steroids and systemic anti-inflammatories, which often come with significant side effect profiles.
The ongoing Phase 2 KLARITY trial investigating two dose levels across multiple inflammatory retinal conditions will be pivotal in determining which specific indication(s) offer the strongest efficacy signal. This adaptive trial design allowing for dose expansion based on initial results demonstrates efficient clinical development strategy, potentially accelerating time-to-market for the most promising applications.
For a clinical-stage biotech company, this patent strengthens Kiora's negotiating position for potential partnerships or licensing deals while providing a substantial runway for commercialization efforts should KIO-104 receive regulatory approval.
Encinitas, California--(Newsfile Corp. - July 22, 2025) - Kiora Pharmaceuticals, Inc. (NASDAQ: KPRX) today announced it has received a patent (US Patent No. 12,364,680) covering KIO-104 for the treatment of a wide range of ocular diseases. This includes, but is not limited to, the following conditions: ocular inflammation, uveitis, age-related macular degeneration, and complications from refractive surgery. Additionally, the patent covers varying dosing schedules, necessary excipients, among other novel methods for optimizing treatment of ocular inflammatory diseases. This patent issuance is expected to further strengthen the protection of KIO-104 and extend market exclusivity into 2043.
"Securing this patent builds on our IP strategy to protect KIO-104 around its proprietary structure, delivery methods, formulation, and therapeutic applications," said Brian M. Strem, PhD, President & Chief Executive Officer of Kiora Pharmaceuticals. "This specific patent is significant in its breadth of therapeutic applications."
KIO-104 is a potent small molecule in development for inflammatory retinal diseases. It offers an alternative to steroids or systemic anti-inflammatory drugs, both of which have established limitations including undesirable side effects.
A multicenter Phase 2 clinical trial, the KLARITY study, is currently screening patients to investigate KIO-104 in up to 28 patients at two dose levels across several forms of inflammatory retinal disease. These diseases include posterior non-infectious uveitis and diabetic macular edema, conditions where inflammation is associated with vision-threatening changes. Results from the initial stage of the study will inform dose expansion into one or more specific indications.
KIO-104 works by inhibiting the mitochondrial enzyme DHODH, which plays a crucial role in the synthesis of key building blocks of DNA and RNA. Without these, T-cell replication is significantly reduced. These building blocks also serve as key cofactors required for T-cell function. Having fewer building blocks thus also dampens the ability of T-cells to drive inflammation.
