ZUG, Switzerland, and BOSTON, USA, May 31, 2023 – Oculis Holding AG (Nasdaq: OCS) (“Oculis”), a global biopharmaceutical company purposefully driven to save sight and improve eye care, announces that Arshad M Khanani, MD, MA, Co-Principal Investigator for Oculis’ Phase 3 DIAMOND trial and member of Oculis’ Scientific Advisory Board, will present the Stage 1 top line results of OCS-01 eye drops in DME in the “First-Time Results of Clinical Trials’ session at Clinical Trials at the Summit (CTS), on June 10, 2023.

Dr Khanani, who is Director of Clinical Research at Sierra Eye Associates and Clinical Associate Professor at University of Nevada, Reno School of Medicine, will speak about Oculis’ recently completed Stage 1 of its Phase 3 DIAMOND trial, exploring the potential of OCS-01 eye drops in Diabetic Macular Edema (DME).

Arshad M. Khanani, M.D., M.A, Director of Clinical Research at Sierra Eye Associates and Clinical Associate Professor at University of Nevada, Reno School of Medicine, Reno, Nevada and Co-Principal Investigator for the DIAMOND trial, commented: I feel privileged to be presenting  the clinically meaningful Stage 1 top line results to my retina colleagues and to initiate discussions on how a topical treatment, such as OCS-01 eye drops, could change our current treatment paradigm, if approved.”

In Stage 1, OCS-01 met primary and secondary endpoints with robust statistical significance, validating the loading and maintenance dosing regimen designed to optimize OCS-01 efficacy potential. Stage 2 of the trial, which is expected to commence in the second half of this year, includes two global trials, each enrolling approximately 350-450 patients.

Riad Sherif M.D., CEO of Oculis, said: I would like to thank the organizer of Clinical Trials at the Summit for including the presentation of the DIAMOND Stage 1 results into its prestigious program. It is the perfect event to introduce these results to the retina community given its timing and most importantly, its esteemed audience. We look forward to the discussions with world-renowned retina experts following Dr. Khanani’s presentation.”

Clinical Trials at the Summit brings together a diverse group of experts from around the world to discuss ongoing clinical trials and the latest data, focused on advancements in vitreoretinal care.

 About OCS-01 eye drops and the OPTIREACH® technology

Leveraging Oculis’ proprietary Optireach® technology, OCS-01 is a novel, high concentration (15 mg/ml), topical formulation of dexamethasone. It is developed to reach the retina via an eye drop, a route of administration for DME that is in contrast with currently available therapies, all requiring the use of more invasive treatments such as ocular implants or intravitreal injections to deliver the medication to the retina. The Optireach® solubilizing formulation technology addresses the main limitations of conventional eye drops by improving the solubility of lipophilic drugs, increasing the residence time on the eye surface and thereby, enabling the drug passage from the eye surface to the posterior segment of the eye.

 About Diabetic Macular Edema (DME)

DME is the leading cause of visual loss and legal blindness in patients with diabetes. Currently, it is estimated to affect around 37 million people worldwide and, with the rise of diabetes, the prevalence is expected to increase to 53 million by 20401,2. DME is an irreversible and progressive complication of diabetic retinopathy and is related to consistently high blood sugar levels that damage nerves and blood vessels in the macula, the area of the retina responsible for sharp vision. DME occurs when blood vessels in the retina swell, and then leak, leading to a fluid build-up (edema) into the retina. There remains a significant need for safer, more effective, longer lasting, and less burdensome treatments for DME patients.
