Clearside Biomedical, Inc. Redirects Pre-Clinical AMD Research Resources Toward Ongoing DME Clinical Development Program

ALPHARETTA, Ga., Feb. 27, 2017 (GLOBE NEWSWIRE) -- Clearside Biomedical, Inc. (NASDAQ:CLSD), a late-stage biopharmaceutical company developing first-in-class drug therapies to treat back-of-the-eye diseases, today announced that it has initiated a strategic realignment of its research and development resources from its pre-clinical development program for axitinib for the treatment of wet age-related macular degeneration (“wet AMD”) toward its ongoing clinical development program for the treatment of diabetic macular edema (“DME”) assessing ZuprataTM, its proprietary suspension formulation of the corticosteroid triamcinolone acetonide.

In mid-2016, Clearside announced that it had selected axitinib as the lead compound for the treatment of wet AMD through suprachoroidal administration due to its potency in targeting the VEGF and PDGF receptors, and because of its long half-life when administered suprachoroidally.

However, recent trial results from other industry participants that are pursuing combination therapy agents for wet AMD have led Clearside to reconsider the viability of further development of its proprietary suspension formulation of axitinib.  Accordingly, while the Company plans to continue to investigate axitinib and other compounds for the treatment of wet AMD, it no longer expects to submit an Investigational New Drug application to the U.S. Food and Drug Administration for axitinib.  Instead, Clearside will shift research and development resources away from wet AMD towards its more advanced DME program.

“Clearside is fortunate to have built a well-diversified pipeline targeting the restoration and preservation of vision,” said Daniel H. White, Clearside’s Chief Executive Officer and President. “Historically, corticosteroids have shown promise in the treatment of DME, but the results have been confounded by side effects like cataracts and elevated intraocular pressure. We believe that the encouraging results that we have observed in our RVO and Uveitis programs suggest that suprachoroidally injected Zuprata may exhibit similar benefits in treating DME.  Clearside will, however, continue to explore potential opportunities for the use of suprachoroidal delivery in the wet AMD space.”

In November 2016, Clearside announced the enrollment of the first patient in a Phase 1/2 clinical trial (“HULK”) assessing the administration of Zuprata, either alone or together with EYLEA® (aflibercept), for the treatment of DME. Suprachoroidally injected Zuprata for the treatment of DME is part of Clearside’s pipeline of drug treatments for unmet or underserved blinding eye diseases where the pathologies manifest in the choroid or retina.
