Evelo Biosciences Announces Fourth Quarter and Full Year 2022 Financial Results and Business Highlights
CAMBRIDGE, Mass., March 16, 2023 – Evelo Biosciences, Inc. (Nasdaq: EVLO), (“Evelo” or the “Company”) a clinical stage biotechnology company developing a novel platform of orally delivered inflammation-resolving medicines acting on the small intestinal axis, SINTAX, today reported financial results and business highlights for the fourth quarter and full year 2022.
“We continued to progress on our SINTAX platform and our clinical pipeline in 2022. We look forward to important clinical milestones in 2023. On mechanism of action, we have shown that the action of SINTAX medicines in the small intestine generates systemically circulating regulatory T cells. These T cells have the potential to induce durable resolution of inflammation throughout the body, as observed in Part B of the EDP1815 Phase 2 study in psoriasis announced in 2022” said Simba Gill, Ph.D., Chief Executive Officer. “We also developed a faster release capsule in 2022 which we expect to improve exposure of drug substance to the target of the upper regions of the small intestine. Our first clinical testing of the faster release capsule is in a placebo controlled fourth cohort of our ongoing atopic dermatitis Phase 2 trial of EDP1815, for which we anticipate reporting results in the second quarter of this year.”
Dr. Gill continued, “Additionally, we have progressed our first oral extracellular vesicle (EV) clinical program. We announced in February 2023 that our product candidate, EDP2939, also formulated with the faster release capsule, is now in the clinic. Following a Phase 1 safety review in the first cohort of our healthy human volunteers, we have started dosing in a Phase 2 study in moderate plaque psoriasis patients. The Phase 2 clinical readout is expected in the second half of 2023.”
2022 Highlights
In February 2022, the Company reported data from Part B of EDP1815 Phase 2 trial in psoriasis, demonstrating durable and deepening responses in the post-treatment period.
18/30 patients maintained a PASI-50 or greater response
9/20 patients experienced a deepening of response from PASI-50 to at least PASI-75
In May 2022, the Company raised $79.2 million through a Registered Direct Offering of common stock, led by Flagship Pioneering with participation from key existing and new investors.
In December 2022, Evelo refinanced its existing $45 million debt by executing a loan and security agreement with Horizon Technology Finance which provides for three years of interest-only payments, followed by a two-year amortization period.
Evelo received feedback from the U.S. Food and Drug Administration (“FDA”), European Medicines Agency (“EMA”) and Medicines and Healthcare products Regulatory Agency (“MHRA") regarding a proposed Phase 3 study of EDP1815 in psoriasis, advancement into which is funding dependent, including the following:
Agreement on primary endpoint of PGA 0/1 with a 2-point improvement
No need for active comparator in Europe, with placebo control acceptable in the mild-to-moderate population
Alignment on Chemistry, Manufacturing and Controls plan for release and stability testing panels
Evelo published a peer-reviewed article in Frontiers in Immunology explaining the scientific basis of the Small Intestinal Axis (“SINTAX”).
Upcoming Milestones
EDP1815 – Atopic Dermatitis
Data from a fourth patient cohort of the Phase 2 study in atopic dermatitis evaluating the faster release capsule is anticipated in 2Q 2023.
Cohorts one, two and three did not meet the primary endpoint of EASI-50 improvement as compared to placebo, due to an unusually high placebo response. No conclusions regarding the cause of the high placebo response have been identified.

EDP2939 – Psoriasis
A safety and tolerability review was conducted in a first cohort of healthy volunteers in the Phase 1 portion of the trial, with no safety or tolerability concerns identified and resulting in approval to start the Phase 2 part of trial.
In February 2023, Evelo began dosing psoriasis patients in the Phase 2 portion of the trial, with data expected 2H 2023.
Safety and tolerability assessment of multiple ascending dose cohorts continues, as the Company anticipates conducting additional dose-ranging studies following acceptable safety and tolerability data.
Fourth Quarter and Full Year 2022 Financial Results (Unaudited)

About Evelo Biosciences
Evelo Biosciences is a clinical stage biotechnology company developing a novel platform of orally delivered anti-inflammatory medicines acting on the small intestinal axis, SINTAX, with systemic therapeutic effects. The small intestine plays a central role in governing inflammation throughout the body. The Company’s product candidates are pharmaceutical preparations of single strains of microbes or their extracellular vesicles (EVs). Evelo initially is developing EDP1815 in psoriasis and atopic dermatitis and EDP2939 in psoriasis. 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. 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.
