CAMBRIDGE, Mass., Feb. 17, 2022 (GLOBE NEWSWIRE) -- Evelo Biosciences, Inc. (Nasdaq:EVLO), a clinical stage biotechnology company developing SINTAX™ medicines as a new modality of orally delivered treatments for inflammatory disease, today announced that the first patient has been dosed in EDP1815-207, its Phase 2 randomized clinical trial of EDP1815 for the treatment of patients with mild, moderate, and severe atopic dermatitis.

“We are pleased that dosing has begun in the Phase 2 trial to evaluate the potential of this novel product candidate to benefit people worldwide who are living with atopic dermatitis,” said Jonathan Zung, Ph.D., Chief Development Officer of Evelo. “Our previously released Phase 1b data, together with the positive results we recently released from our Phase 2 trial in mild and moderate psoriasis, demonstrate that EDP1815 has the potential to be a safe, effective, well tolerated, oral, inflammation resolving therapy.”

“Patients and prescribers are in need of a therapy that is safe and well tolerated, as well as orally delivered, for the treatment of atopic dermatitis” said Benjamin Ehst, M.D., Ph.D., Board-certified Dermatologist, Investigator and Clinical Associate Professor with the Oregon Medical Research Center, and Chief Investigator of EDP1815-207. “The integrated safety, tolerability, and efficacy data seen in the Phase 2 trial of EDP1815 in psoriasis, along with its oral administration and potential to be affordably priced, could provide meaningful change to the treatment paradigm for patients living with atopic dermatitis.”

Topline results from the Phase 2 clinical trial are expected in 1H 2023.

About the EDP1815 Phase 2 Clinical Trial
EDP1815-207 is a 16-week, multi-center, double-blind, placebo-controlled Phase 2 trial for the treatment of mild, moderate, and severe atopic dermatitis. Approximately 300 patients will be randomized, across approximately 60 sites globally, into one of three cohorts – each cohort has ~100 patients randomized in a 3:1 ratio (75 to EDP1815 and 25 to placebo). Cohort 1 will be administered a dose of 1.6 x 1011 total cells of EDP1815, or matching placebo administered as two capsules once daily. Cohorts 2 & 3 will be administered a dose of 6.4 x 1011 total cells of EDP1815, or matching placebo administered as two capsules once daily or one capsule twice daily, respectively. The primary endpoint is percentage of patients achieving an EASI-50 at week 16. Key physician-reported secondary endpoints are IGA (Investigator Global Assessment) and BSA (Body Surface Area). Key patient-reported secondary endpoints are DLQI (Dermatology Life Quality Index), POEM (Patient-Oriented Eczema Measure), and Pruritus-NRS (Numerical Rating Scale).

About EDP1815
EDP1815 is an investigational oral medicine being developed for the treatment of inflammatory diseases. It is a non-live pharmaceutical preparation of a strain of Prevotella histicola, selected for its potential to provide systemic pharmacological effects after oral administration with gut-restricted distribution. Being non-live, it has not been observed to colonize the gut or modify the microbiome. Preclinically, EDP1815 had anti-inflammatory effects in models that cover multiple pathways of inflammation, Th1, Th2, and Th17. Clinical results from multiple independent cohorts provide evidence supporting EDP1815’s potential to address Th1, Th2 and Th17-mediated inflammation.
