Kiora Pharmaceuticals Receives European Orphan Medicinal Product Designation for KIO-301 for the Treatment of Inherited Retinal Dystrophies

Encinitas, California--(Newsfile Corp. - July 30, 2024) - Kiora Pharmaceuticals (NASDAQ: KPRX) ("Kiora" or the "Company") today announced it has received Orphan Medicinal Product Designation from the European Medicines Agency (EMA) for the treatment of a group of inherited retinal diseases (IRDs) that include retinitis pigmentosa (RP), choroideremia and more. The broad designation covers KIO-301, a small molecule photoswitch, for the treatment of non-syndromic rod-dominant retinal dystrophies. This classification of dystrophies, in simplified terms, refers to rare diseases from underlying genetic mutations resulting in predominantly and primarily the degeneration of rod photoreceptors, the cells responsible almost entirely for night vision as well as peripheral and non-color vision. In RP, which today has no approved therapeutics, rods degenerate first followed by degeneration of cone photoreceptors, the cells responsible for color and central vision. This degenerative process causes partial or severe loss of vision and may result in complete blindness. There are approximately 92 million rods in the human eye compared to approximately 6 million cones.

"This designation provides Kiora and our development and commercialization partner, Théa Open Innovation, with at least ten years of market exclusivity, exclusive of patent protection, in Europe. This is in addition to other regulatory and market access benefits," said Eric Daniels, M.D., Chief Development Officer of Kiora Pharmaceuticals. "With Orphan Drug Designation already granted in the U.S., KIO-301 is well positioned for expediated regulatory guidance, review, and market exclusivity in two major marketplaces. We are finalizing the design and planning to initiate the Phase 2 trial of KIO-301 (ABACUS-2) later this year."

In addition to market exclusivity, additional benefits of Orphan Medicinal Product Designation includes:

  • A centralized process for EU market approval;

  • Reduced or waived fees for regulatory activities; and

  • EMA scientific advice and protocol assistance to optimize trial design.

The European Union provides Orphan Medicinal Product Designation to incentivize drug developers to bring products for rare diseases to market that may otherwise not be developed. The designation is granted after a critical review and only if a drug candidate meets specific criteria, which incudes but is not limited to the following:

  • The investigational therapy is medically plausible and intended to treat a serious or life-threatening disease; and

  • The condition affects no more than 5 in 10,000 people in the EU.
