Opthea Completes Enrollment in Pivotal Phase 3 Clinical Program with Sozinibercept in Wet AMD
Phase 3 program enrolled 1,984 patients across COAST and ShORe trials
Trials designed to replicate superiority in visual outcomes demonstrated in Phase 2b
Topline data from both pivotal trials expected in mid-CY2025
MELBOURNE, Australia and PRINCETON, N.J., May 28, 2024 -- Opthea Limited (ASX/NASDAQ: OPT “Opthea”, the “Company”), a clinical-stage biopharmaceutical company developing novel therapies to treat highly prevalent and progressive retinal diseases, including wet age-related macular degeneration (wet AMD), today announced that it has now completed enrollment in both the COAST and ShORe trials constituting its pivotal Phase 3 clinical program. This program is designed to assess the safety and superior efficacy of sozinibercept in combination with standard-of-care anti-VEGF-A therapies compared to standard of care alone for the treatment of patients with wet AMD.
“Today marks the achievement of a key milestone for the sozinibercept global Phase 3 clinical trial program that brings us closer to our goal of improving visual outcomes for patients with wet AMD,” said Arshad M. Khanani, MD, MA, FASRS, Chief Medical Advisor of Opthea. “In a large Phase 2b clinical trial of 366 treatment-naïve wet AMD patients, sozinibercept demonstrated strong clinical evidence of superior visual outcomes in combination with ranibizumab. These data formed the basis for this large, global Phase 3 clinical program.”
Opthea’s Phase 3 clinical program consists of two multicenter, double-masked, randomized, sham-controlled trials COAST (Combination OPT-302 with Aflibercept Study) and ShORe (Study of OPT-302 in combination with Ranibizumab), which enrolled 1,984 treatment-naïve wet AMD patients in total (998 patients in COAST; 986 patients in ShORe), making it one of the largest Phase 3 programs in wet AMD. Both Phase 3 trials combine sozinibercept with standard-of-care anti-VEGF-A therapy to assess the efficacy and safety of intravitreal 2.0 mg sozinibercept in combination with 2.0 mg aflibercept (COAST), or 0.5 mg ranibizumab (ShORe), compared to standard of care alone. The primary endpoint for both trials is the mean change in Best Corrected Visual Acuity (BCVA) from baseline to week 52. Both trials are also evaluating the safety and tolerability over a two-year period.
“Sozinibercept is the only late-stage asset in development in over 15 years that is targeting better visual outcomes for wet AMD patients in combination with standard-of-care anti-VEGF-A therapies,” said Frederic Guerard, PharmD, Chief Executive Officer of Opthea. “We are excited about the potential of sozinibercept to transform the current treatment paradigm, with pivotal 52-week topline data expected in mid-CY2025 to support a potential BLA submission.”
About Sozinibercept
Sozinibercept (OPT-302) is a soluble form of vascular endothelial growth factor receptor 3 (VEGFR-3) expressed as an immunoglobulin G1 (IgG1) Fc-fusion protein. It binds and neutralizes the activity of VEGF-C and VEGF-D on their endogenous receptors,
VEGFR-2 and VEGFR-3. VEGF-C and VEGF-D are known to independently stimulate retinal angiogenesis and vascular leakage and permeability, while VEGF-A inhibition can also lead to the upregulation of VEGF-C and VEGF-D. Research shows that the targeted inhibition of VEGF-C and VEGF-D with sozinibercept can prevent blood vessel growth and vascular leakage, which both contribute to the pathophysiology of retinal diseases, including wet AMD.
About Opthea’s Clinical Development Program
In Opthea’s prospective, randomized and controlled Phase 2b trial including 366 treatment-naïve wet AMD patients, sozinibercept was administered in combination with standard-of-care ranibizumab for the treatment of wet AMD. Sozinibercept combination therapy met the pre-specified primary efficacy endpoint of a statistically superior gain in visual acuity at 24 weeks, compared to ranibizumab alone. In addition, secondary outcomes were positive with the combination therapy, including more patients gaining vision of 10 or more letters, improved anatomy, with a reduction in swelling and vascular leakage, and a favorable safety profile. These statistically significant results were published in Ophthalmology in February 2023.
The Company is currently conducting two concurrent pivotal Phase 3 multicenter, double-masked, randomized, sham-controlled clinical trials, COAST (Combination OPT-302 with Aflibercept Study) and ShORe (Study of OPT-302 in combination with Ranibizumab), designed to assess the safety and superior efficacy of sozinibercept combination therapy versus standard-of-care anti-VEGF-A for the treatment of wet AMD. Opthea’s Phase 3 clinical trial program is designed to support a broad label and, if successful, sozinibercept has the potential to be approved for use in combination with any anti-VEGF-A for the treatment of all wet AMD patients. Sozinibercept has received Fast Track Designation from the U.S. FDA for the treatment of wet AMD.

Inherent risks of Investment in Biotechnology Companies
There are a number of inherent risks associated with the development of pharmaceutical products to a marketable stage. The lengthy clinical trial process is designed to assess the safety and efficacy of a drug prior to commercialization and a significant proportion of drugs fail one or both of these criteria. Other risks include uncertainty of patent protection and proprietary rights, whether patent applications and issued patents will offer adequate protection to enable product development, the obtaining of necessary drug regulatory authority approvals and difficulties caused by the rapid advancements in technology. Companies such as Opthea are dependent on the success of their research and development projects and on the ability to attract funding to support these activities. Investment in research and development projects cannot be assessed on the same fundamentals as trading and manufacturing enterprises. Therefore, investment in companies specializing in drug development must be regarded as highly speculative. Opthea strongly recommends that professional investment advice be sought prior to such investments.
