MELBOURNE, Australia, Oct. 19, 2021 (GLOBE NEWSWIRE) -- Opthea Limited (ASX:OPT; Nasdaq:OPT), a clinical stage biopharmaceutical company developing novel therapies to treat highly prevalent and progressive retinal diseases, today announced that the first clinical trial sites in the Asia-Pacific region are now open for patient enrollment into the OPT-302 Phase 3 pivotal clinical program for the treatment of wet (neovascular) age-related macular degeneration (AMD). The clinical trial sites, located in Australia, further build upon the progress of other international regions including the U.S., Canada and Europe that are also actively recruiting patients.

“We are delighted to open enrollment in the Asia-Pacific region. This is a significant milestone for the OPT-302 development program and enables eligible patients to participate in the ShORe and COAST Phase 3 trials which are designed based on strong scientific rationale, prior positive clinical efficacy results and extensive safety data in the wet AMD target population. Over the following weeks we anticipate opening sites in additional countries in the Asia Pacific region including South Korea and the Philippines,” said Dr Megan Baldwin, CEO and Managing Director of Opthea.

The ShORe and COAST studies are both double‑masked, sham‑controlled Phase 3 registrational trials to evaluate efficacy and safety of intravitreal 2.0 mg OPT‑302 in combination with either 0.5 mg ranibizumab (Lucentis®), or 2.0 mg aflibercept (Eylea®) respectively. The primary endpoint of the studies is the mean change in best corrected visual acuity from baseline to week 52 for OPT‑302 combination therapy compared to standard of care anti‑VEGF‑A monotherapy. The read-out of the top-line results through 52 weeks is anticipated in the second half of 2023, and following completion of this primary efficacy phase, the Company plans to file Biologics License and Marketing Authorization Applications with the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA) respectively.

Recently, the FDA granted Fast Track status for OPT-302, in combination with anti-VEGF-A therapy for the treatment of patients with wet AMD and this regulatory designation offers benefits to help advance development and expedite the review of novel therapies for serious conditions for which there is an unmet medical need, with the aim of getting important new therapies to patients more quickly.

About Opthea

Opthea (ASX:OPT; Nasdaq:OPT) is a biopharmaceutical company developing novel therapies to address the unmet need in the treatment of highly prevalent and progressive retinal diseases, including wet age-related macular degeneration (wet AMD) and diabetic macular edema (DME). Opthea’s lead product candidate OPT-302 is in pivotal Phase 3 clinical trials and being developed for use in combination with anti-VEGF-A monotherapies to achieve broader inhibition of the VEGF family, with the goal of improving overall efficacy and demonstrating superior vision gains over that which can be achieved by inhibiting VEGF-A alone.

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.
