{Abstract}: UNASSIGNED: Psoriasis is a chronic inflammatory skin disease. EDP1815 is an oral, gut-restricted preparation of non-live Prevotella histicola, the first of a new immunomodulatory therapeutic class targeting the small intestine to generate systemic anti-inflammatory responses.
UNASSIGNED: To evaluate safety and efficacy of EDP1815 in mild-to-moderate psoriasis in a proof-of-concept study.
UNASSIGNED: A phase 2, multicenter, randomized, double-blinded, placebo-controlled, parallel-group study with a 16-week treatment period and up to 24 weeks of follow-up. Participants were randomized to receive 1, 4, or 10 capsules daily.
UNASSIGNED: EDP1815 was well tolerated with comparable rates of treatment-emergent adverse events to placebo, and no drug-related serious adverse events. Clinically meaningful responses to EDP1815, defined as at least 50% reduction in Psoriasis Area and Severity Index (PASI-50) at week 16, were observed in all 3 cohorts, statistically significant in the 1-capsule (29.7%; P = 0.048) and 4-capsule (31.9%; P = 0.022) groups, compared with placebo (12.1%). Among EDP1815-treated PASI-50 responders at week 16, 60% (18/30) maintained or improved off-treatment responses at week 40.
UNASSIGNED: Continued off-treatment improvement past 16 weeks shows potential for greater therapeutic benefit that was not assessed.
UNASSIGNED: EDP1815 was well-tolerated with a placebo-like safety profile, and had meaningful efficacy outcomes in psoriasis, validating this novel immunomodulatory approach.
