MELBOURNE, Australia, Aug. 30, 2022 (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 reported financial results for the fiscal year ended June 30, 2022 and provided an overview of recent progress.

“Over the past year, Opthea has focused on advancing our Phase 3 clinical trials investigating OPT-302 as a combination therapy for wet AMD. We have continued to recruit patients globally into both ShORe and COAST trials and expect to complete patient recruitment for both trials in mid CY2023 and to report topline data in mid CY2024,” said Dr. Megan Baldwin, CEO and Managing Director of Opthea. “We believe the strategic relationship with Launch Therapeutics and funding from leading investors Carlyle and Abingworth of up to US$170 million serve as an affirmation of the significant amount of work we have achieved to date and strengthens our strategic position to maximize the value of OPT-302.”

Corporate Highlights

• In August 2022, Opthea announced a non‐dilutive financing transaction for up to US$170 million from Carlyle and its life sciences franchise Abingworth, working with their recently formed development company Launch Therapeutics (Launch Tx). The financing consists of a US$120 million commitment and an option for Launch Tx to increase funding by a further US$50 million. If OPT‐302 is approved in a major market, Carlyle and Abingworth will be eligible to receive fixed success payments, as well as variable success payments of 7% on annual net sales, which collectively terminate after reaching four times the funded amount.
• In March 2022, Opthea announced the appointment of Dr. Joel Naor, M.D., as Chief Medical Officer (CMO).
• In January 2022, Ms. Judith Robertson was appointed as the Company’s first Chief Commercial Officer (CCO), after having formerly served as a non‐executive member of the Opthea Board of Directors.
• Over the past 12 months, the Company further expanded its Board of Directors, which included welcoming Mr. Quinton Oswald and Dr. Susan Orr who have deep experience leading biotechnology companies and launching commercial products for the treatment of wet AMD and other ophthalmic diseases.

About Opthea Limited

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.
