Evelo Biosciences to Present Clinical Data from Phase 1/2 Trial of EDP1503 at the ESMO World Congress on Gastrointestinal Cancer Virtual Meeting

July 1, 2020 at 7:08 AM EDT

CAMBRIDGE, Mass., July 01, 2020 (GLOBE NEWSWIRE) -- Evelo Biosciences, Inc. (Nasdaq:EVLO), a clinical stage biotechnology company developing a new modality of orally delivered, systemically acting biologics, today announced that clinical data from the Phase 1/2 open-label study of EDP1503, in combination with pembrolizumab, in patients with advanced metastatic microsatellite stable colorectal carcinoma (MSS CRC), triple-negative breast cancer (TNBC), and checkpoint inhibitor relapsed tumors, will be presented at the ESMO World Congress on Gastrointestinal Cancer Virtual Meeting being held July 1 - 4, 2020.

In addition to data in MSS CRC patients, the poster reported preliminary data on 11 TNBC patients (8 on high dose and 3 on low dose EDP1503). An overall response rate (ORR) of 25% (2/8) and a disease control rate of 37.5% (3/8) were observed across all TNBC subjects receiving high dose EDP1503. ORR was 33% (2/6) amongst response-evaluable patients on the high dose, with 2 patients awaiting first response assessment. Historic studies of anti-PD-1 monotherapy in heavily pretreated TNBC patients have yielded an ORR of 5-10%. The study continues enrollment in TNBC, and further data from this cohort will be available in 4Q 2020.

Details of the poster are as follows:
