Oculis Announces First Patient First Visit in Phase 3 OPTIMIZE-2 Trial of OCS-01 for the Treatment of Inflammation and Pain Following Cataract Surgery


  • Initiation of the second Phase 3 OPTIMIZE-2 trial with OCS-01 once daily eye drop, follows the recently reported positive OPTIMIZE-1 trial results
  • OPTIMIZE-2 topline readout expected before end of 2024 to support NDA submission
  • OCS-01 is also being evaluated as potentially the first topical eye drop treatment for Diabetic Macular Edema (DME) in the DIAMOND program and for the treatment of Cystoid Macular Edema (CME) in the LEOPARD trial

ZUG, Switzerland, and BOSTON, Dec. 20, 2023 (GLOBE NEWSWIRE) -- Oculis Holding AG (Nasdaq: OCS) (“Oculis” or “the Company”), a global biopharmaceutical company purposefully driven to save sight and improve eye care, today announced First Patient First Visit (FPFV) in OCS-01 Phase 3 OPTIMIZE-2 trial for the treatment of inflammation and pain following cataract surgery. Data from the Phase 3 OPTIMIZE-2 trial is intended to support the Company’s NDA submission to the Food and Drug Administration (FDA). If approved, OCS-01 has the potential to be the first once-daily, topical, preservative-free corticosteroid for treating inflammation and pain following ocular surgery.

The OPTIMIZE-2 (Once-daily Post-ocular surgery Treatment for InflaMmation and paIn to minimiZE drops) is a multi-center, randomized, double-masked, vehicle-controlled Phase 3 trial evaluating OCS-01 for the treatment of inflammation and pain following cataract surgery. Similar to the OPTIMIZE-1 trial, patients in the second Phase 3 OPTIMIZE-2 trial will be treated with once-daily OCS-01 post-cataract surgery versus vehicle for 2 weeks. Primary endpoints are the absence of anterior chamber cells (inflammation) on Day 15 and absence of pain on Day 4. The OPTIMIZE-2 trial follows the positive topline results from the OPTIMIZE-1 trial showing that OCS-01 increased the percentage of patients who were inflammation free at Day 15 and had zero pain at Day 4 vs. vehicle with statistical significance (p<0.0001 for both endpoints), and was well tolerated.

Moreover, the initiation of OPTIMIZE-2 follows the start of Stage 2 of the Phase 3 DIAMOND trial of OCS-01 in DME announced earlier this week, and the commencement of the investigator-initiated LEOPARD trial of OCS-01 in patients with CME announced earlier this year.

Riad Sherif, M.D., Chief Executive Officer of Oculis, remarked: “Initiation of the OPTIMIZE-2 trial preceded by the launch of OCS-02 RELIEF Phase 2b trial in dry eye, and OCS-01 DIAMOND-1 trial in DME in the past couple weeks, highlights our robust pipeline and ability to execute and deliver on commitments. This timely progress also underscores the steadfast advancement of the OCS-01 development program thus far, as well as OCS-01’s potential as an eye drop treatment for both front- and back-of-the-eye diseases. We look forward to the important milestones expected in the year ahead, including four topline clinical readouts from OPTIMIZE-2 and the LEOPARD trials with OCS-01, the RELIEF trial with OCS-02, and from the ACUITY trial in Acute Optic Neuritis (AON) with OCS-05.”

Eric Donnenfeld, M.D., Clinical Professor of Ophthalmology at New York University and Co-chair of Oculis Scientific Advisory Board, said: “I was excited to see the positive efficacy results and the favorable safety profile from the first Phase 3 OPTIMIZE trial and the consistency with the prior Phase 2 results. Once daily OCS-01 could become an attractive option to treat pain and inflammation after ocular surgery with a highly potent anti-inflammatory effect. This could be especially beneficial for high-risk patients, such as diabetic patients, who face an increased risk of complications following ocular surgery due to pre-existing underlying inflammation.”

About inflammation and pain following ocular surgery
Ophthalmic surgeries are on the rise, mainly due to the aging population and lifestyle changes, and are expected to reach close to 10 million procedures per year in the U.S. alone by 20371,2. Cataract surgeries are the most prevalent procedures of all medical specialties with an estimated 5 million procedures in 2021 in the US2. Ophthalmic surgeries cause the release of inflammatory factors and can be associated with ocular pain. Cataract surgery, even with a very small incision, creates inflammation in the cornea, anterior chamber, and iris. Ophthalmologists currently rely on topical steroids to treat ocular inflammation and the full regimen following ocular surgery often includes steroids, antibiotics and NSAID, which can have a different dosing regimen and require several drops daily for a post-op patient to administer, all leading to potential compliance issues.

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. 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 less frequent administration for front-of-the-eye and the drug passage from the eye surface to the posterior segment for back-of-the-eye diseases.
