Clearside Biomedical Announces First Patient Randomized in Phase 2 Clinical Trial of CLS-TA Used Together with Eylea in Patients with Diabetic Macular Edema

07/11/17

ALPHARETTA, Ga., July 11, 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 the enrollment of the first patient in a phase 2 clinical trial (“TYBEE”) of CLS-TA for suprachoroidal administration (“suprachoroidal CLS-TA”), Clearside’s proprietary suspension formulation of the corticosteroid triamcinolone acetonide, used together with intravitreally administered EYLEA® (aflibercept) (“intravitreal Eylea”) for the treatment of diabetic macular edema (“DME”).

TYBEE is a multicenter, randomized, masked, controlled phase 2 clinical trial designed to evaluate the safety and efficacy of suprachoroidal CLS-TA along with intravitreal Eylea, compared to intravitreal Eylea monotherapy, in patients with DME who are naïve to pharmacologic treatment.  In this trial, patients with DME will be randomized into either a combination arm of patients receiving suprachoroidal CLS-TA together with intravitreal Eylea or a control arm of patients receiving only intravitreal Eylea. The primary outcome measure will be a comparison between the two study arms of change from baseline in best corrected visual acuity at 3 months.

“We believe that eye complications associated with diabetes are caused by multiple pathways in this difficult to treat disease, and that we can improve the visual outcomes for newly diagnosed DME patients by administering suprachoroidal CLS-TA together with an intravitreal anti-VEGF inhibitor like Eylea,” said Daniel H. White, Chief Executive Officer and President of Clearside. “The enrollment of the first patient in the TYBEE trial represents an important step forward in Clearside’s DME clinical development program and we currently expect to report three-month preliminary data in the first half of 2018.”

CLS-TA for suprachoroidal administration, used either alone or together with an intravitreal anti-VEGF agent, is part of Clearside’s pipeline for the treatments of unmet or underserved blinding eye diseases where the pathologies manifest in the choroid and retina.
