TARRYTOWN, N.Y., Aug. 24, 2021 /PRNewswire/ —
Phase 3 trials in wet AMD and diabetic macular edema were fully recruited, with results expected in the second half of 2022
Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) today announced that an ongoing Phase 2 proof-of-concept trial evaluating an investigational 8 mg dose of aflibercept met its primary safety endpoint, with no new safety signals observed compared to the currently-approved 2 mg dose of EYLEA® (aflibercept) Injection in patients with wet age-related macular degeneration (wet AMD). In this small trial involving 106 patients, a higher proportion of patients in the aflibercept 8 mg group had no retinal fluid (43.4%, n=23/53) compared to patients treated with EYLEA 2 mg (26.4%, n=14/53) (p=0.067) at week 16, the primary efficacy endpoint. At this time point, patients had received three initial doses (administered at weeks 0, 4, and 8), after which dosing was extended.
Aflibercept 8 mg is currently being evaluated in two large Phase 3 trials in wet AMD and diabetic macular edema (DME), which are expected to report results in the second half of 2022. The trials will assess the safety and efficacy of aflibercept 8 mg for up to two years, with visual acuity as the primary efficacy endpoint at 48 weeks, measured by the Early Treatment Diabetic Retinopathy Study (ETDRS) Best Corrected Visual Acuity (BCVA). Both trials will assess aflibercept 8 mg compared to EYLEA 2 mg, testing dosing intervals of every 12 weeks and every 16 weeks.
“We are cautiously optimistic that these early data suggest that a higher dose of aflibercept may potentially benefit patients with wet AMD, and we look forward to Phase 3 data next year, which will be crucial to understand its overall efficacy and safety,” said George D. Yancopoulos, M.D., Ph.D., President and Chief Scientific Officer of Regeneron. “Having worked for nearly two decades in retinal disease, we know that large, robust data sets are required to fully understand whether a medicine can achieve three critical things: improved visual and anatomic outcomes, convenient dosing, and a safety profile that is consistent with EYLEA.”….
