Evelo Biosciences, Inc. announced data for EDP1815, the Company's lead product in inflammation, detailing its mechanism of action and supporting further clinical development in patients with psoriasis and atopic dermatitis. The data were presented in two posters on Saturday, January 15, 2022, at the 2022 Winter Clinical Dermatology Congress in Koloa, Hawaii. Preclinical data from the studies presented at the Winter Clinical Dermatology Congress confirm that EDP1815 modulates systemic inflammation through its initial interaction with innate immune receptors, including TLR2, leading to downstream changes in circulating immune-cell phenotypes.

In addition, the data demonstrate that preclinical effects in Th17 models translate into signs of clinical benefit in psoriasis, and that preclinical effects in Th2 models translate into signs of clinical benefit in atopic dermatitis, supporting further clinical development of EDP1815 in these indications. A Phase 2 study of EDP1815 in patients with mild to moderate psoriasis is ongoing, and a Phase 2 study of EDP1815 in patients with mild, moderate, and severe atopic dermatitis is expected to initiate dosing in the first quarter of 2022.
