Kiora Pharmaceuticals Receives Investigational New Drug Approval to Initiate ABACUS-2, a Phase 2 Clinical Trial of KIO-301 for the Treatment of Retinitis Pigmentosa
Kiora Pharmaceuticals (NASDAQ: KPRX) received regulatory approval to initiate ABACUS-2, a Phase 2 clinical trial for KIO-301 in retinitis pigmentosa patients. The trial will involve 36 patients across five Australian centers, with participants randomized 2:1 to receive KIO-301 or control. The study will evaluate two dosage levels (50 and 100 micrograms) administered intravitreally every 6 weeks. KIO-301 is a photoswitch molecule designed to restore vision by targeting retinal ganglion cells, potentially benefiting patients regardless of their specific gene mutation. The trial's primary endpoints include safety and tolerability, with efficacy measured through functional vision assessments.

- Received regulatory approval for Phase 2 clinical trial
- Novel therapy potentially effective across 150+ gene mutations
- Partnership with Théa Open Innovation strengthens development
- Multiple dose study design with control group increases data reliability
- Potential for single Phase 3 trial pathway to market approval
- Trial initiation delayed until next year pending endpoint validation
- No current approved therapies in market space indicates regulatory uncertainty
- patient size (36) in Phase 2 trial
Insights
This Phase 2 trial approval for KIO-301 represents a significant milestone in addressing the unmet medical need in retinitis pigmentosa treatment. The 36-patient study incorporates several important design elements that strengthen its potential success:
- Double-masked, randomized controlled design with a 2:1 treatment ratio
- Novel functional vision endpoints developed with regulatory input
- Multiple dose assessment (50μg vs 100μg) with 3-month follow-up
- Cross-over option for control group patients
The trial's focus on functional vision outcomes aligns with regulatory requirements for approval. KIO-301's mechanism as a photoswitch targeting retinal ganglion cells could potentially benefit patients regardless of genetic mutation - a key differentiator in the market. However, investors should note that meaningful results won't be available until well into 2024, given the endpoint validation work needed before first patient dosing.

Encinitas, California--(Newsfile Corp. - October 29, 2024) - Kiora Pharmaceuticals, Inc. (NASDAQ: KPRX) ("Kiora" or the "Company") today announced it received regulatory approval to initiate a Phase 2 clinical trial to investigate KIO-301 for vision restoration in patients with retinitis pigmentosa. The ABACUS-2 trial will be a 36 patient, multi-center, double-masked, randomized, controlled, multiple dose study enrolling patients with ultra-low vision or no light perception regardless of their underlying gene mutation associated with retinitis pigmentosa. Dosing of the first patient with KIO-301 is expected to begin next year following validation of novel functional vision endpoints. These functional assessments may serve as approvable primary endpoints in subsequent registration studies in the United States, Europe and other major regions.
"There are unfortunately no approved therapies for patients with retinitis pigmentosa," said Eric Daniels, M.D., Chief Development Officer at Kiora. "This study represents a significant step toward addressing this challenge. Prior to submission for approval, we engaged with European and US regulators to incorporate their expectations and guidance for approvable endpoints. Consistent with historical approval in other inherited retinal disease, both regulatory bodies emphasized the need to measure a therapy's effect on everyday functional vision. For this reason, we are investing time upfront to validate the functional endpoints for ABACUS-2, increasing our likelihood of success in a potential single Phase 3 trial for market approval in the US and Europe. This validation work is being performed, in collaboration with our partner Théa Open Innovation, with the support of the Choroideremia Research Foundation as part of a grant to design a standard endpoint for investigational therapies of inherited retinal diseases."
Kiora has identified and is now contracting with trial sites and clinical investigators at major inherited retinal disease reference centers across Australia. Patients will be randomized 2:1 to receive KIO-301 intravitreally or control. Treatment will be delivered to both eyes. Participants will be randomized to receive either a high dose (100 micrograms) or low dose (50 micrograms) of KIO-301 and after trial participants receive three consecutive doses (6 weeks apart), they will be followed for three months. Following this phase of the study, patients in the control arm may elect to cross-over into the active arm. Primary endpoints will consist of safety and tolerability, and key efficacy assessments include: functional vision; visual acuity as measured by the Berkeley Rudimentary Vision Test; visual fields as measured by perimetry, and a validated ultra-low vision quality-of-life questionnaire. The trial will be conducted across five centers within Australia.
"In a short window since entering our partnership with Kiora, tremendous progress has been made on advancing KIO-301 toward ABACUS-2," said Dr. Céline Olmiere, Head of Théa Open Innovation. "What makes KIO-301 compelling is that it appears, based on the Phase 1b data, to have potential for meaningful vision restoration. Further, because of its unique mechanism of action, it has the potential to work across all 150-plus underlying gene mutations associated with retinitis pigmentosa and other inherited retinal diseases."
KIO-301 is a small molecule that acts as a light-sensitive photoswitch that has the potential to return vision to patients living with reduced sight due to inherited retinal diseases. The novel compound is activated in the presence of light and deactivated in the absence of light. Because hundreds of gene mutations underlie inherited retinal diseases like retinitis pigmentosa, there is an important need for therapies like KIO-301 that have the potential to act in a gene mutation agnostic manner.
KIO-301 targets and enters specialized cells of the retina (retinal ganglion cells or RGCs) that are located 'downstream' of degenerated rods and cones, the cells normally responsible for converting light to vision. KIO-301, when inside RGCs, is activated by visible light and confers light-sensing capabilities by altering the flow of ions in and out of the cell, thus giving RGCs the ability to facilitate visual processing. This is a reversible process allowing turning on and off the RGCs in the presence and absence of light.
