Treatment with UNI-494 improved contrast vision in animal models of geographic atrophy (GA)
GA is an advanced form of Age-related Macular Degeneration (AMD) and there are currently no
FDA-approved drugs to slow the progression of AMD
LOS ALTOS, Calif., Nov. 21, 2022 (GLOBE NEWSWIRE) -- Unicycive Therapeutics, Inc. (Nasdaq: UNCY), a clinical-stage biotechnology company developing therapies for patients with unmet medical needs, today announced key findings of UNI-494 efficacy from a preclinical study in animal models of Geographic Atrophy (GA).
UNI-494 is a mitochondrial potassium channel (mitochondrial KATP) activator in development for treating diseases affected by mitochondrial dysfunction, such as kidney, liver, and ocular diseases. Mitochondrial dysfunction is implicated in Age-related Macular Degeneration (AMD) progression. GA is an advanced form of AMD. The Company evaluated the effect of UNI-494 in preventing visual function loss in a rat model of GA.
The study evaluated four groups (n=8 per group): untreated, vehicle control, low dose of UNI-494, and high dose of UNI-494. GA was induced by bilateral subretinal injection of sodium iodate in experimental animals. UNI-494 was administered orally twice a day (BID) for 20 days, with the first administration of UNI-494 starting before sodium iodate injection. Contrast vision was measured by optokinetic tracking. Treatment of animals with the high dose of UNI-494 resulted in 150% and 200% improvement in contrast vision compared to vehicle and untreated animals. Further preclinical studies are planned to investigate these promising findings of the effect of UNI-494 in improving visual function.
“We are excited to report that UNI-494 improved visual function in well-established rat models of GA, which is responsible for 10-20% of blindness in AMD, a disease that affects five million people globally. Contrast sensitivity is widely accepted as a critical aspect of visual function and has been shown to correlate with ability to perform instrumental activities of daily living,” said Shalabh Gupta, M.D., Chief Executive Officer of Unicycive.
“Importantly, these data support UNI-494’s mechanism of action, which holds promise for indications in which mitochondrial dysfunction is implicated, such as kidney disease, liver disease and other ophthalmic diseases. Our goal is to remain focused and advance UNI-494 in kidney disease, and to explore partnerships for other indications in order to maximize the potential of this promising new therapeutic. Toward that end, we remain on track to initiate a Phase I study in healthy volunteers during the first quarter of 2023 in the UK following clearance by the Medicines and Healthcare products Regulatory Agency (MHRA),” concluded Dr. Gupta.
About UNI-494
UNI-494 is a novel proprietary drug that selectively binds to the SUR2B subunit of the mitochondrial KATP channel and activates it to restore mitochondrial function and reduce oxidative stress. UNI-494 is cleaved by esterase enzymes to form nicorandil, the active metabolite. Nicorandil has extensive safety, and efficacy data from multiple clinical trials, including a 5,000-patient randomized controlled trial (IONA Study) and there is a consensus in the literature that the activation of mitoKATP channel is the biological basis for the observed cardio-protection and reno-protection in multiple clinical trials.
Unicycive has completed all non-clinical safety assessment studies required for regulatory filing to initiate a Phase I study in healthy volunteers. The Company is on track to initiate the Phase I healthy volunteer study.
UNI-494 is protected by issued patent(s) in the U.S. and Europe and a wide range of patent applications worldwide.
