ZUG, Switzerland, May 11, 2026 (GLOBE NEWSWIRE) -- Oculis Holding AG (NASDAQ:OCS) (Oculis), a global biopharmaceutical company focused on breakthrough innovations to address significant unmet medical needs in ophthalmology and neuro-ophthalmology, today announced results for the first quarter ended March 31, 2026, and provided an overview of the Company's progress.

Riad Sherif, M.D., Chief Executive Officer of Oculis, stated, "We began 2026 with strong execution momentum across our late-stage clinical trials. We are positioned for a pivotal year, with key readouts for OCS-01 in diabetic macular edema (DME) expected in June and Licaminlimab in dry eye disease (DED) around year-end, while the Privosegtor PIONEER program is making significant progress, including PRIME designation in Europe and an agreement with the FDA on the Special Protocol Assessment (SPA) regarding PIONEER-1 and ongoing centers activation. Driven by a mission to restore vision, we are targeting global market opportunities exceeding $30 billion."

Recent Development Highlights and Upcoming Milestones:

OCS-01:

Last patient last visit (LPLV) completed in the DIAMOND (DIAbetic Macular edema patients ON a Drop) program, consisting of two Phase 3, double-masked, randomized, multi-center trials to evaluate the efficacy and safety of OCS-01 eye drops in patients with DME following 52-weeks of treatment. Topline results are expected to readout in June 2026, and, if positive, an NDA submission to the FDA is planned for Q4 2026.
The DME AWARE Delphi study results were recently presented at the 17^th annual congress on Controversies in Ophthalmology (COPHy) and at the Association for Research in Vision and Ophthalmology (ARVO) 2026 annual meeting. In this study, supported by Oculis, 25 leading global retina and ophthalmology experts were surveyed to establish consensus on unmet needs in DME. Among other results, the DME AWARE Delphi study revealed broad consensus on the need for novel therapies to enable early treatment. In fact, consensus was reached: 70% of respondents agreed they would initiate therapy with a non-invasive treatment following a 5-letter BCVA vision loss, compared with 5% with the current standard of care, intravitreal treatments. This strongly aligns with our efforts to develop OCS‑01 eye drops and our ambition to potentially bring to market the first non‑invasive topical treatment for DME.
Despite available therapies, in the U.S. alone, an estimated 1 million patients out of the 1.8 million people diagnosed with the disease remain untreated with mild to moderate vision impairments, or are inadequately responding to the current standard of care.^1,2,3 OCS-01 is intended to be strategically positioned to capture this significant opportunity by providing a non-invasive, topical eye drop for those requiring early intervention and a versatile option for patients who do not respond to existing injections.

Licaminlimab:

In prior Phase 2 studies, Licaminlimab showed a substantially greater treatment effect in patients carrying a specific TNFR1 genotype, with profound improvements ranging from 5-fold greater in signs to 7-fold greater in symptoms. PREDICT-1 is designed to leverage these findings to deliver potentially the first precision medicine treatment in ophthalmology and topline results (TLR) are expected to read out around year end.
In the U.S. alone, approximately 10 million patients suffer from moderate to severe DED.⁴ Current disease management relies on trial and error, with a minority (~13%) of patients reporting sustained relief,⁵ leading to an 85-90% discontinuation rate within the first 6 months, underscoring the strong need for a targeted, effective treatment approach.⁶ Licaminlimab has the potential to transform the current DED treatment paradigm by providing a precision medicine approach with high efficacy, rapid onset of action, and a comfort level similar to artificial tears.

Privosegtor:

Privosegtor was granted PRIME (PRIority MEdicines) designation by the EMA (European Medicines Agency), a highly selective process to provide early and proactive support to developers of promising medicines that may offer a major therapeutic advantage over existing treatments or provide benefits to patients without treatment options. These medicines are considered priority medicines by the EMA, which aims to optimize development plans and expedite evaluations so that medicines addressing significant unmet medical needs can reach patients faster. This follows the recent granting of Breakthrough Therapy designation for Privosegtor for the treatment of optic neuritis (ON) by the U.S. Food and Drug Administration (FDA), reinforcing global regulatory support for this unique neuroprotective asset.
Special Protocol Assessment (SPA) agreement received from the FDA regarding the design of the PIONEER-1 (Privosegtor Investigation in Optic Neuropathies Efficacy Evaluation Research) registrational trial of Privosegtor in ON. The SPA agreement established a clear pathway to NDA and validates that the clinical trial protocol, size, planned analysis and endpoints are adequate to address scientific and regulatory requirements to support marketing approval, subject to a successful outcome of the trial and review of all data in the NDA. The design of PIONEER-2 is planned to be identical to PIONEER-1. With no currently approved neuroprotective treatments for ON, this SPA agreement is a critical step toward aligning with the FDA on our PIONEER development program.
Oculis' PIONEER program, supported by the positive Phase 2 ACUITY trial, includes three registrational trials in ON and non-arteritic anterior ischemic optic neuropathy (NAION). These two optic neuropathies can cause permanent visual impairments and represent a potential market opportunity estimated at $7+ billion in the U.S. alone.

Q1 2026 Financial Highlights:

As of March 31, 2026, Oculis held cash, cash equivalents and short-term investments of CHF 222.0 million or $277.6 million, compared to CHF 213.0 million or $268.7 million as of December 31, 2025. The increase in cash, cash equivalents, and short-term investments was primarily due to proceeds received from sales under the Company's existing at-the-market offering program during the quarter, offset by planned operating expenses. Research and development expenses were CHF 14.0 million or $17.9 million for the three months ended March 31, 2026, compared to CHF 14.8 million or $16.4 million in the same period in 2025. The decrease was primarily due to a reduction in spending on external service providers as the DIAMOND program approaches completion and topline data readout. General and administrative expenses were CHF 7.9 million or $10.1 million for the three months ended March 31, 2026, compared to CHF 5.5 million or $6.1 million in the same period in 2025. The increase was primarily driven by share-based compensation expense due to the increased value of awards granted after Q1 2025. The Company's net loss was CHF 28.9 million or $36.8 million for the quarter ended March 31, 2026, compared to CHF 33.2 million or $36.9 million for the same period in 2025. The decrease was primarily due to a CHF 3.9 million or $5.0 million lower non-cash fair value loss on warrant liabilities resulting from decreased warrant shares outstanding compared to Q1 2025, and a favorable foreign currency fluctuation due to favorable U.S. dollar versus Swiss Franc spot rates for U.S. dollar denominated transactions and assets, compared to a weaker U.S. dollar against the Swiss Franc in the prior year period.
