ZUG, Switzerland, Aug. 06, 2026 (GLOBE NEWSWIRE) -- Oculis Holding AG (Nasdaq: OCS / XICE: OCS) (Oculis), a global biopharmaceutical company focused on breakthrough innovations to address significant unmet medical needs in neuro-ophthalmology and ophthalmology, today announced results for the second quarter ended June 30, 2026, and provided an overview of the Company’s progress.

Riad Sherif, M.D., Chief Executive Officer of Oculis, stated, “We continue to advance and expand the Privosegtor neuroprotection franchise, with PIONEER-1 on track in global site activations and positive regulatory momentum supporting our development strategy in acute multiple sclerosis relapses. Given the considerable unmet need for neuroprotective treatments, these achievements reinforce both our strategy to pivot to neuro-ophthalmology by exploring the clinical potential of Privosegtor and the substantial opportunity across multiple neuro-ophthalmic and neuro-axonal diseases. In parallel, with Licaminlimab PREDICT-1 genotype-based trial planned site activations complete and over 45% of patients enrolled, we expect to report topline results around year-end. With a strong balance sheet, we are well positioned to execute on our strategy, advance our registrational programs and deliver on upcoming value-driving milestones.”

Recent Development Highlights and Upcoming Milestones:

 Privosegtor:

• The PIONEER-1 registrational trial is designed to investigate Privosegtor as a neuroprotective treatment for patients with optic neuritis (ON) across a broad population, including those with and without multiple sclerosis (MS). As established under a Special Protocol Assessment (SPA) agreement with the FDA, the primary endpoint is defined as the proportion of patients achieving at least a 15-letter gain from baseline in low-contrast visual acuity (LCVA) at Month 3, a clinically meaningful visual function endpoint in ON. The primary analysis will be conducted at Month 3, and patients will be followed through Month 12 to assess Privosegtor’s long-term safety and tolerability. Site activation is actively progressing across the U.S., Europe, Australia, and Canada, with an execution focus and priority on building a robust, multidisciplinary network connecting emergency room physicians, ophthalmologists, and neurologists. This integrated approach aims to optimize operational flows from patient identification to treatment, capitalizing on peak enrollment opportunities during the fall, winter, and spring to align with the natural seasonality of the disease.
• The FDA’s Division of Neurology provided guidance that no additional preclinical studies will be required ahead of an Investigational New Drug (IND) submission for Privosegtor in acute MS relapses, cross-referencing the data from the open ON IND residing in the Division of Ophthalmology. Constructive FDA feedback also supports the proposed clinical development strategy and regulatory pathway, which will include MS patients with both optic neuritis and other relapses, such as ambulatory relapses, in future trials. It also supports a primary endpoint as early as 3 months, with the same 3mg/kg dose administered daily for 5 days as in PIONEER-1. Oculis anticipates an IND submission for the treatment of acute MS relapses in the fourth quarter of 2026.
• MS is a chronic immune-mediated disease of the central nervous system affecting approximately 2.8 million people worldwide, including around 850,000 in the U.S. alone.^1-3 There are two main types of MS: relapsing-remitting MS (RRMS) and progressive MS. While progressive MS remains a significant unmet medical need, RRMS is the most common type, representing ~85% of patients at initial diagnosis.² Despite available therapies, relapses still persist for many patients, with an estimated 170,000 MS relapses occurring each year in the U.S.^4,5 During an acute relapse, neurologists commonly use a short course of high-dose corticosteroids to reduce inflammation and shorten the episode, as is standard of care in optic neuritis. However, corticosteroids do not influence the frequency of future relapses or long-term disability, and recovery from relapses is often incomplete. There are currently no neuroprotective therapies approved for MS relapses, and there remains an urgent unmet medical need for treatments that can prevent central nervous system damage.
• The Company will host an R&D Day in Q4 to share key updates on Privosegtor’s ongoing clinical development in optic neuritis and acute MS relapses.
  
  

Licaminlimab:

• Oculis is actively enrolling patients in the PREDICT-1 genotype-based registrational trial in dry eye disease (DED) evaluating Licaminlimab as a precision medicine treatment. All planned trial sites have been activated and >45% patients have been randomized. The PREDICT-1 trial is a randomized, multi-center, double-masked, vehicle-controlled study that plans to enroll ~160 patients of whom approximately 2/3 will have the specified TNFR1 genotype. The primary endpoint is the change from baseline to Day 29 in the global ocular discomfort severity score in patients with the specified TNFR1 genotype. The same outcome measure will be evaluated in the overall study population as a key secondary endpoint. While measurements of dry eye symptoms are inherently subjective, this precision medicine approach is designed to identify patients more likely to benefit from Licaminlimab.
• In the U.S., approximately 10 million diagnosed patients suffer from moderate to severe DED.^6,7 Current disease management relies on a trial-and-error therapeutic approach, with a minority (~13%) of patients experiencing sustained relief,⁸ leading to an 85-90% discontinuation rate within the first 6 months,⁹ underscoring the significant unmet need for a targeted, effective treatment approach. If approved, 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.
  
  

OCS-01

• Following the DIAMOND topline results announcement in May, at this time Oculis does not plan to pursue an FDA regulatory filing for OCS-01 in DME.
  
  

Q2 2026 Financial Highlights:

As of June 30, 2026, Oculis held cash, cash equivalents and short-term investments of CHF 228.3 million or $282.3 million, compared to CHF 213.0 million or $268.7 million as of December 31, 2025. The increase reflects proceeds from sales of ordinary shares year-to-date under the Company’s existing at-the-market offering program, offset by operating expenses. Research and development expenses were CHF 15.3 million or $19.3 million for the three months ended June 30, 2026, compared to CHF 14.9 million or $18.1 million in the same period in 2025. General and administrative expenses were CHF 8.6 million or $10.9 million for the three months ended June 30, 2026, compared to CHF 6.1 million or $7.4 million in the same period in 2025. The increase in operating expenses was primarily driven by headcount-related costs, including share-based compensation expenses, to support and execute the Company’s development strategies. The Company’s net loss was CHF 38.8 million or $49.3 million for the six months ended June 30, 2026, compared to CHF 58.6 million or $67.9 million for the same period in 2025. The decrease was primarily due to the fair value gain on warrant liabilities in 2026 driven by decreased market value as well as a favorable foreign currency fluctuation resulting from favorable U.S. dollar versus Swiss Franc for U.S. dollar denominated transactions and assets, compared to a weaker U.S. dollar against the Swiss Franc in the prior year period.
