Kiora Pharmaceuticals to Present Additional Data from Its ABACUS-1 Trial in Retinitis Pigmentosa at the ARVO 2024 Annual Meeting

Encinitas, California--(Newsfile Corp. - March 28, 2024) - Kiora Pharmaceuticals, Inc. (NASDAQ: KPRX), ("Kiora" or the "Company") announced that additional data from the ABACUS-1 trial has been accepted for presentation at the Association for Research in Vision and Ophthalmology (ARVO) meeting in Seattle, WA, May 5-9, 2024. The additional data includes quantitative evaluation of the functional MRI measures. Qualitative assessment of fMRI demonstrated reactivation of the regions of the brain responsible for vision in a time-dependent manner, consistent with other improvements in visual function.

The presentation, titled, "Synthetic phototransduction with a light-responsive molecule (KIO-301) in advanced retinitis pigmentosa: the ABACUS-1 phase I/II trial," will be presented by Professor Robert James Casson, DPhil, Head of Ophthalmology and Visual Science at Adelaide University. The ABACUS-1 study was a Phase I/II first-in-human clinical trial of the Company's molecular photoswitch, KIO-301, in patients with late-stage retinitis pigmentosa (RP). Initial preliminary topline results from ABACUS-1 were announced at the American Academy of Ophthalmology (AAO) annual conference in November 2023.

About KIO-301

KIO-301 is a small molecule photoswitch. It is designed to selectively confer light-sensing capabilities to retinal ganglion cells (RGCs). In healthy eyes, light is first converted to electrical signals via the rods and cones (photoreceptors) and transmitted through RGCs to the vision perceiving part of the brain (visual cortex). In many inherited retinal diseases (IRDs), genetic mutations cause photoreceptors to degenerate and die off, affecting an individual's ability to perceive light. However, while photoreceptors degenerate in IRDs, RGCs are preserved. They therefore represent a target cell to bypass degenerated photoreceptors, perceive light, and signal the brain. It has been shown KIO-301 selectively enters RGCs downstream of degenerated photoreceptors. In the presence of light, KIO-301 turns to an "on" position, triggering the RGC to signal the brain. In the absence of light, KIO-301 turns to an "off" position and signaling to the brain stops. In this way, the molecule acts as a light switch within the eye.

In January of 2024, Kiora granted Théa Open Innovation (TOI), a sister company of the global ophthalmic specialty company Laboratoires Théa (Théa), exclusive worldwide development and commercialization rights, excluding Asia, to KIO-301 for the treatment of degenerative retinal diseases. As part of this agreement, the companies are jointly planning a Phase 2 multicenter, controlled clinical trial for retinitis pigmentosa.
