CAMBRIDGE, Mass., Nov. 14, 2022 (GLOBE NEWSWIRE) -- Evelo Biosciences, Inc. (Nasdaq:EVLO), a clinical stage biotechnology company developing a novel platform of orally delivered medicines acting on the small intestinal axis, SINTAX, today announced its third quarter 2022 financial results and business highlights.

“We are on-track to deliver on three Phase 2 clinical milestones throughout 2023: first, early in the first quarter of 2023, data from the first three cohorts in the Phase 2 trial of EDP1815 in atopic dermatitis; second, in the second quarter of 2023, data from the fourth cohort - the faster release capsule – in the Phase 2 trial of EDP1815 in atopic dermatitis; and third, in the second half of 2023, data from patients in the Phase 2 trial of EDP2939, our first extracellular vesicle (EV) product candidate, in psoriasis” said Simba Gill, Ph.D., Chief Executive Officer of Evelo.

Dr. Gill continued, “We are pleased that the European Medicines Agency (EMA) and the United Kingdom Medicines and Healthcare products Regulatory Agency (MHRA), through their respective scientific advice processes, acknowledged the appropriateness of our proposed registration clinical trial design for EDP1815 in psoriasis, including the primary and secondary endpoints. We have also received initial written feedback from the United States Food and Drug Administration (FDA) on the same topics and have requested a meeting to discuss our registration trial plans. We have the technical and manufacturing operations in place that we believe will allow for registration trials and commercial launch.”

Third Quarter 2022 Highlights and Upcoming Key Milestones

EDP1815 in Atopic Dermatitis: On-Track for Phase 2 Data Read-outs in Early 1Q 2023 (cohorts 1-3) and 2Q 2023 (cohort 4)

• Recruitment for the first three cohorts in the Phase 2 trial of EDP1815 in atopic dermatitis is complete. Cohorts 1 - 3 are currently testing different concentrations, as well as twice daily administration versus once daily administration of the original capsule that had been used in previous clinical trials with EDP1815. Data are expected early in the first quarter of 2023.
• Recruitment for the fourth cohort is ahead of schedule, with data expected in the second quarter of 2023. The fourth cohort is testing a faster release capsule, which targets the upper part of the small intestine more effectively and has demonstrated greater efficacy than the original capsule in pre-clinical trials.
  

EDP2939 in Psoriasis: Dosing Expected in 1Q 2023; Phase 2 Data Anticipated in 2H 2023

• In November 2022, the Company received a request from the MHRA for additional information with respect to the Clinical Trial Application (CTA) submission for the EDP2939 Phase 1/2 trial. The Company is currently in the process of providing written responses to the MHRA questions, and anticipates dosing healthy volunteers in Part A of the trial in the first quarter of 2023, with Part B (the Phase 2 trial) to follow.
• Phase 2 data in the cohort of patients with psoriasis are still expected in the second half of 2023.

EDP1815 in Psoriasis: Regulatory Feedback on Proposed Registration Trials

• The Company has completed scientific advice meetings and received feedback from the EMA and MHRA on the proposed registration trial design of EDP1815 in psoriasis, including the primary and secondary endpoints. Both agencies provided supportive feedback regarding critical components of the chemistry, manufacturing and control (CMC) for the proposed registration trials.
• Initial written feedback was received from the FDA. A meeting with the FDA has been requested to discuss the Company’s registration trial plan.

Recent Presentations

• In September 2022, Evelo presented a poster at the 2022 European Academy of Dermatology and Venereology (EADV) Congress. The poster included biomarker data demonstrating the broad anti-inflammatory effects of EDP1815 in a Phase 2 clinical trial in psoriasis. Treatment with EDP1815 led to a statistically significant reduction in the release of cytokines IL-6, IL-8, and TNF in stimulated blood cells compared to placebo. In addition, RNAseq analysis of skin biopsies taken from active lesions in a subset of patients who had achieved at least a 50% improvement in their Psoriasis Area and Severity Index (PASI) score (PASI-50) from baseline at week 16 showed reductions in disease relevant cytokines IL-23, IL-12b, and IL-17. This provides evidence of a systemic anti-inflammatory effect in addition to the tissue response.
• In September 2022, Evelo gave two presentations at the 5-Continent-Congress (5CC). The first presentation discussed the use of extracellular vesicles for the treatment of inflammatory diseases, and the second presentation discussed the treatment of psoriasis via the small intestine.
• In October 2022, Evelo presented two posters at the 2022 Fall Clinical Dermatology Conference. The posters described the significant unmet medical need identified by dermatologists and primary care physicians in the U.S. for new treatment options for patients with mild and moderate psoriasis and atopic dermatitis.

Evelo Biosciences is a clinical stage biotechnology company developing a novel platform of orally delivered medicines acting on the small intestinal axis, SINTAX, with systemic therapeutic effects. SINTAX plays a central role in governing the immune, metabolic, and neurological systems. The Company’s product candidates are pharmaceutical preparations of single strains of microbes or their extracellular vesicles (EVs). Evelo’s vision is to create therapies that are effective, safe, well-tolerated, and affordable to improve the lives of the billions of people living with inflammatory diseases. Evelo initially is developing EDP1815 in psoriasis and atopic dermatitis and EDP2939 in psoriasis. If shown to be effective in inflammatory disease mediated by the Th1, Th2 or Th17 inflammatory pathways, these same investigational medicines could be effective in additional inflammatory diseases, such as psoriatic and other forms of arthritis, asthma, allergy, and inflammatory bowel disease.
