Ocuphire Announces APX3330 Phase 2 Data Presentations at Retina Meetings
Topline Data from ZETA-1 Phase 2 Trial of Oral APX3330 in Diabetic Retinopathy Presented on February 11th at 20th Angiogenesis, Exudation, and Degeneration 2023 Meeting
Topline Data from ZETA-1 Accepted for Presentation on February 17th at Macula Society 46th Annual Meeting
Presentations Highlight Binocular 3-Step or More DRSS Worsening Measure in the ZETA-1 Phase 2 Trial; This Pre-Specified Secondary Endpoint Met by APX3330 is the Planned Potential Phase 3 Primary Registration Endpoint
FARMINGTON HILLS, Mich., Feb. 16, 2023 (GLOBE NEWSWIRE) -- Ocuphire Pharma, Inc. (Nasdaq: OCUP), clinical-stage ophthalmic biopharmaceutical company focused on developing and commercializing therapies for the treatment of refractive and retinal eye disorders, today announced two presentations featuring efficacy and safety results from the Company’s recently completed ZETA-1 Phase 2 trial of oral APX3330 in diabetic retinopathy (DR) at two medical meetings in February. Peter Kaiser, M.D., Professor of Ophthalmology at the Cleveland Clinic Lerner College of Medicine and Cole Eye Institute, presented the results at the Angiogenesis, Exudation, and Degeneration 2023 Meeting held virtually on February 10-11, 2023. Rishi P. Singh, M.D., President of Cleveland Clinic Martin North and South hospitals, and Professor of Ophthalmology at the Lerner College of Medicine, will present at the upcoming Macula Society 46th Annual Meeting, to be held in-person February 15-18, 2023 in Miami, FL.
Dr. Kaiser’s presentation, titled “Efficacy and Safety Data for APX3330, a Novel Oral Drug Candidate for DR/DME, from the ZETA-1 Phase 2 Trial,” discussed results from the trial during the Diabetic Retinopathy Imaging and Treatment session at the 20th Angiogenesis, Exudation, and Degeneration 2023 Meeting on Saturday, February 11th organized by the Bascom Palmer Eye Institute. Oral APX3330 achieved statistical significance on a key pre-specified secondary DRSS (diabetic retinopathy severity scale) endpoint of preventing clinically meaningful progression of DR after 24 weeks of treatment. In addition, APX3330 demonstrated a favorable systemic and ocular safety and tolerability profile.
Dr. Kaiser noted, “The Phase 2 clinical trial results of the oral drug candidate APX3330 that were presented at the Angiogenesis 2023 meeting showed favorable efficacy, safety, and tolerability. Intravitreal injections are currently approved for DR based on 2-step improvement in DRSS in one eye. What was new for many retina specialists is that for a systemic medication that works in both eyes, the use of binocular improvement or prevention of worsening in DRSS is an acceptable endpoint for FDA approval. We would prefer to treat our DR patients early and non-invasively, so an oral treatment option that prevents worsening of DR would be very appealing.”

About Ocuphire Pharma
Ocuphire is a publicly traded (Nasdaq: OCUP), clinical-stage, ophthalmic biopharmaceutical company focused on developing and commercializing small-molecule therapies for the treatment of refractive and retinal eye disorders.
Ocuphire has a previously disclosed partnership to develop and commercialize Nyxol® eye drops as a preservative-free eye drop formulation of phentolamine mesylate, a non-selective alpha-1 and alpha-2 adrenergic antagonist designed to reduce pupil size by uniquely blocking the alpha-1 receptors found only on the iris dilator muscle without affecting the ciliary muscle. Nyxol has been studied in a total of 12 clinical trials (3 Phase 1, 5 Phase 2, 4 Phase 3) across three indications, including single-use for reversal of pharmacologically-induced mydriasis (RM), and once-daily for treatment of presbyopia and dim light (night) vision disturbances (DLD), pending regulatory approvals. Nyxol’s NDA under the 505(b)(2) pathway for the first indication RM has been accepted with a PDUFA date assigned of September 28, 2023, and is currently in Phase 3 for presbyopia and DLD.
Ocuphire’s other late-stage product candidate APX3330 is a first-in-class, small molecule, oral drug that blocks downstream pathways regulated by transcription factor Ref-1 – including those involving angiogenesis (VEGF) and inflammation (NFkB). These pathways are implicated across several ocular diseases, including diabetic retinopathy (DR), diabetic macular edema (DME), and age-related macular degeneration (AMD). Ocuphire recently announced topline data from the ZETA-1 Phase 2 trial in which APX3330 achieved statistical significance on a key pre-specified secondary endpoint of preventing clinically meaningful progression of (DR) after 24 weeks of daily treatment. APX3330 has also shown a favorable safety and tolerability profile in diabetic subjects (ZETA-1 trial) and in 11 previous clinical trials conducted in healthy, liver disease, and cancer subjects.
