Evelo Biosciences Inc.’s late-stage efforts with EDP-1815 are forging ahead despite unfavorable data in atopic dermatitis (AD), and talks so far with the U.S. FDA have proven encouraging, the company said. Cambridge, Mass.-based Evelo made public findings from the first three cohorts of the phase II trial with EDP-1815 in AD, where the compound fell short of the primary endpoint: proportion of patients who achieve an outcome of at least a 50% improvement from baseline in Eczema Area and Severity Index (EASI) score compared to placebo at week 16. Evelo blamed an unusually high placebo response rate.
What one analyst characterized as “a little bit of an exotic or at least unusual statistical analysis on the phase II primary endpoint” may have dampened enthusiasm somewhat for Evelo Biosciences Inc.’s results in mild and moderate psoriasis with EDP-1815, but the firm is advancing the compound to registration studies.
A new U.K. trial evaluating drugs for hospitalized patients in the early stages of COVID-19 has elected to test Evelo Biosciences Inc.'s anti-inflammatory monoclonal microbial, EDP-1815, after an earlier trial found it led to favorable anti-inflammatory activity in psoriasis patients.
