• OCS-01 DIAMOND Phase 3 trials in diabetic macular edema (DME) remain on track for topline results expected in Q2 2026
• Licaminlimab PREDICT-1 registrational trial, the first genotype-based trial to drive precision medicine in dry eye disease (DED), expected to start in Q4 2025
• Cash, cash equivalents and short-term investments of $182.2 million as of September 30, 2025 plus recent $110 million financing, extend cash runway into 2029

ZUG, Switzerland, Nov. 10, 2025 (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 third quarter ended September 30, 2025, and provided an overview of the Company's progress.

Riad Sherif, M.D., Chief Executive Officer of Oculis, stated: "Oculis has entered a pivotal stage in its transformation into a leader in ophthalmology and neuro-ophthalmology, powered by its differentiated and innovative portfolio. We are excited about several key developments: OCS-01 eye drops Phase 3 in DME with anticipated readout in Q2 2026, the initiation of a first in class registrational trial with Licaminlimab in precision medicine for DED, and, very importantly, we are thrilled with our positive discussions with the U.S. Food and Drug Administration (FDA), which paved the way to accelerate Privosegtor development in key unmet medical needs. Our recent financing now secures the resources needed for three pivotal trials in optic neuropathies, a potential market opportunity representing approximately $7 billion in the U.S. alone, with no available therapies. Supported by a strong balance sheet and a robust late-stage pipeline, we are well-positioned to achieve 6 pivotal readouts with the current funding, reinforcing our commitment to delivering groundbreaking treatments." 

Recent Clinical Highlights and Upcoming Milestones:

Privosegtor:

• Following a successful meeting with the FDA, Oculis announced the launch of the PIONEER program, which will include three pivotal trials to support registration plans for Privosegtor in AON and NAION (management webcast available here for replay):
  • The first two trials, PIONEER-1 and PIONEER-2, will evaluate Privosegtor following the acute onset of optic neuritis in a broad population consisting of patients with multiple sclerosis (MS) and those without MS. Primary endpoint will be low-contrast visual acuity (LCVA) at 3 months. Dosing and patient enrollment criteria will mirror the positive Phase 2 ACUITY trial, which demonstrated improvement in visual function and anatomical preservation of the retina in patients with AON. PIONEER-1 is expected to initiate in Q4 2025, with PIONEER-2 planned to follow in the first half of 2026.
  • The third trial in the PIONEER program, PIONEER-3, will evaluate Privosegtor after the acute onset of NAION. This study shares the core design and operational elements with PIONEER-1 and PIONEER-2 and is expected to initiate in mid-2026.
  • Running the PIONEER trials concurrently is expected to generate operational synergies, cost efficiencies, and to speed up Privosegtor development timelines.
• Oculis will cross-reference the existing Privosegtor AON Investigational New Drug (IND) when submitting a new IND to the FDA for the acute treatment of relapses in multiple sclerosis (MS).
• Successful ACUITY Phase 2 trial results in patients with AON were presented in late-breaking abstract sessions at the European Society of Retina Specialists (EURETINA) and the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) congresses.

OCS-01:

• DIAMOND Phase 3 trials with OCS-01, aims to be the first eye drop for DME, are fully enrolled with over 800 patients across both trials. Topline results from both DIAMOND Phase 3 trials are expected in Q2 2026 with NDA submission to the FDA planned for 2H 2026.
• DME affects approximately 37 million people worldwide and represents a ~$5 billion market opportunity with high unmet medical needs for early intervention and for patients with inadequate response to standard of care.

Licaminlimab:

• Aligned with the FDA on the genotype-based development plan to drive precision medicine in DED. Registrational trial expected to initiate in Q4 2025 following three positive Phase 2 studies previously completed, including the demonstration of profound effects on TNFR1-positive patients.

Q3 2025 Financial Highlights

As of September 30, 2025, Oculis held cash, cash equivalents and short-term investments of CHF 145.2 million or $182.2 million. Following the October capital raise, the Company's cash, cash equivalents and short-term investments was close to $300 million, before disbursing offering expenses. Research and development expenses were CHF 14.1 million or $17.6 million for the three months ended September 30, 2025, compared to CHF 13.0 million or $15.0 million in the same period in 2024. The increase was primarily due to increase in product development activities and associated personnel expenses. General and administrative expenses were CHF 6.4 million or $8.0 million for the three months ended September 30, 2025, compared to CHF 5.3 million or $6.2 million in the same period in 2024. The increase was primarily driven by share-based compensation expense and external professional services costs. Year-to-date net loss was CHF 75.4 million or $89.7 million for the nine months ended September 30, 2025, compared to CHF 57.1 million or $64.8 million for the same period in 2024. The increase was primarily driven by advancements in clinical development programs, in particular the Phase 3 DIAMOND trials, and a CHF 6.9 million or $8.2 million increase in the non-cash fair value adjustment on warrant liabilities as a result of appreciation of underlying warrant fair value.
