Evelo Biosciences Treats First Patients in Phase 2 Dose-Ranging Trial of EDP1815 for the Treatment of Psoriasis
– Interim data expected by mid-2021 –
“We are pleased to announce the dosing of the first patients in our Phase 2 clinical trial in mild to moderate psoriasis,” said
EDP1815-201 is a double-blind, placebo-controlled, dose-ranging Phase 2 trial designed to evaluate three doses of the enteric capsule formulation of EDP1815 versus placebo in 225 patients with mild to moderate psoriasis over a 16-week treatment period. The primary endpoint is mean reduction in Psoriasis Area and Severity Index (PASI) score at 16 weeks. Key secondary endpoints include other clinical measures of disease such as Physician’s Global Assessment (PGA), Body Surface Area (BSA), PGA x BSA, Psoriasis Symptom Inventory (PSI), Dermatology Life Quality Index (DLQI), and Lesion Severity Score (LSS). Interim data from the study is expected by mid-2021.
About EDP1815 in Psoriasis
EDP1815 is an investigational oral biologic being developed for the treatment of inflammatory diseases. EDP1815 is a strain of Prevotella histicola, selected for its specific pharmacology. In the second and third quarter of 2019, Evelo reported positive Phase 1b interim clinical data in two cohorts of patients with mild to moderate psoriasis. EDP1815 was well tolerated at both doses, with no overall difference reported from placebo. There was a reduction in mean LSS and PASI score after 28 days of dosing in both cohorts who received EDP1815. In the high dose cohort alone, there was a continued reduction in both mean LSS (of 24% vs. placebo of 7%) and PASI score (of 21% vs. placebo of 3%) at 42 days – 14 days following the last dose of the drug. This may indicate a sustained clinical effect and dose response. EPD1815 was also observed to limit the systemic production of multiple inflammatory cytokines, including IL-6, IL-8, TNF, and IL-1, which are well-established mediators of potentially harmful effects in patients with inflammatory diseases.
Psoriasis is a common chronic immune-mediated inflammatory skin disease, affecting up to 3% of the population worldwide. The disease is driven by Th17-inflammation, which results in the formation of thickened red plaques with scaling. Psoriatic lesions can appear anywhere on the body but are most often seen on the knees, elbows, scalp, and lumbar area. There is a strong association with psoriatic arthritis, depression, and metabolic syndrome.
Patients with mild to moderate psoriasis are underserved by current treatments, including topical therapies, which do not control systemic inflammation, have low rates of compliance, or in the case of potent topical steroids, are not recommended for long-term use. The majority of novel therapies, including injectable high-cost biologics, are only approved for patients with moderate to severe disease. Even in this patient population, the majority of eligible patients do not receive biologics, instead opting for topical or oral systemic therapies, which are associated with tolerability issues and/or with monitoring requirements tied to safety concerns.
Evelo currently has four product candidates in development: EDP1815, EDP1867, and EDP2939 for the treatment of inflammatory diseases including psoriasis, atopic dermatitis, and COVID-19, and EDP1503 for the treatment of cancer. Evelo is advancing additional product candidates in other disease areas.
