CAMBRIDGE, Mass., Feb. 14, 2019 (GLOBE NEWSWIRE) — Evelo Biosciences, Inc. (Nasdaq: EVLO) (“Evelo”), a clinical stage biotechnology company developing monoclonal microbials, a potential new modality of oral biologic medicines, today reported financial results and provided a business update for the fourth quarter and full year 2018.

“Our platform opens up the potential for effective, orally delivered, safe and cost-effective medicines for improved treatments of inflammatory diseases and cancers. In 2018, we made significant progress and advanced our first three product candidates into clinical trials across multiple inflammatory diseases and cancers,” said Simba Gill, Ph.D., president and chief executive officer of Evelo. “In 2019, we expect to advance our oncology clinical trials and announce clinical data from our ongoing inflammatory disease clinical trials which may signal the potential for monoclonal microbials as a broadly applicable new modality of medicines.”

2018 and Recent Business Highlights:

Inflammation

• April 2018 – Evelo initiated a placebo-controlled Phase 1b clinical trial of EDP1066 in healthy volunteers and patients with atopic dermatitis or psoriasis. Following completion of each of the three dose-ascending healthy volunteer cohorts, data was reviewed by the trial’s safety review committee and the trial proceeded as planned into cohorts of patients with atopic dermatitis or psoriasis
• November 2018 – Evelo initiated a placebo-controlled Phase 1b clinical trial of EDP1815 in healthy volunteers and patients with atopic dermatitis or psoriasis

Oncology

• November 2018 – Entered into clinical collaboration with Merck to evaluate EDP1503 in combination with KEYTRUDA^® (pembrolizumab), Merck’s anti-PD-1 therapy, in multiple cancer indications
• December 2018 – Evelo initiated an open-label Phase 1/2 clinical trial of EDP1503 in combination with KEYTRUDA in microsatellite stable colorectal cancer, triple-negative breast cancer, and patients with other tumor types that have relapsed on prior PD-1/L1 inhibitor treatment
• January 2019 – The University of Chicago initiated an open-label Phase 2a clinical trial of EDP1503 in combination with KEYTRUDA in naïve melanoma patients and melanoma patients that have relapsed on prior PD-1/L1 inhibitor treatment

Non-Replicating Monoclonal Microbials

• Preclinical studies have shown that non-replicating monoclonal microbials, which have been treated to prevent growth and division, maintain activity, opening up the potential to develop non-replicating monoclonal microbial clinical candidates
• Monoclonal microbial activity is likely driven by recognition of structural motifs by immune cells in the small intestine and is not dependent on engraftment or colonization
• Nominated EDP1867 as a preclinical monoclonal microbial candidate for inflammatory diseases. EDP1867 is the first monoclonal microbial specifically developed as a non-replicating product candidate in Evelo’s pipeline

Anticipated 2019 Clinical Milestones

• Initial clinical data from the ongoing Phase 1b clinical trial of EDP1066 in healthy volunteers and patients with psoriasis or atopic dermatitis in the second quarter of 2019
• Initiation of an immuno-pharmacology clinical study in healthy volunteers with EDP1066 in 1H 2019, designed to explore additional doses and formulations ahead of potential later stage trials
• Initial clinical data from the ongoing Phase 1b clinical trial of EDP1815 in healthy volunteers and patients with psoriasis or atopic dermatitis in the second half of 2019
• Initiation of clinical trials with EDP1066 and EDP1815 in additional inflammatory disease indications in the second half of 2019

Fourth Quarter and Full Year 2018 Financial Results

• Cash Position: As of December 31, 2018, cash, cash equivalents and investments were $147.9 million, as compared to cash and cash equivalents of $38.2 million as of December 31, 2017. This increase was due to net proceeds of $81.3 million from the issuance of Series C convertible preferred stock, net proceeds of $75.8 million from Evelo’s initial public offering and $5.0 million of additional drawings from Evelo’s existing debt facility, partially offset by cash used to fund operating activities for the full year 2018. Evelo expects that its cash, cash equivalents and investments will enable it to fund its planned operating expenses and capital expenditure requirements into the second half of 2020.
• Research and Development Expenses: R&D expenses were $11.3 million for the three months ended December 31, 2018 and $39.9 million for the full year ended December 31, 2018, compared to $6.1 million for the three months ended December 31, 2017 and $20.0 million for the full year ended December 31, 2017. The increase of $19.9 million for 2018 was due primarily to increases in costs related to Evelo’s inflammation and oncology clinical development programs, and gut-body network platform expenses, as well as increased personnel costs.
• General and Administrative Expenses: G&A expenses were $4.7 million for the three months ended December 31, 2018 and $18.2 million for the full year ended December 31, 2018, compared to $2.0 million for the three months ended December 31, 2017 and $7.6 million for the full year ended December 31, 2017. The increase of $10.6 million for 2018 was due primarily to increased general and administrative personnel costs, professional and consulting fees, and facility expenses supporting Evelo’s growing organization and public company infrastructure.
• Net Loss Attributable to Common Stockholders: Net loss attributable to common stockholders was $15.4 million for the three months ended December 31, 2018 and $60.9 million for the full year ended December 31, 2018, or $(0.49) and $(2.78) per basic and diluted share, respectively, as compared to a net loss attributable to common stockholders of $9.9 million for the three months ended December 31, 2017 and $34.1 million for the full year ended December 31, 2017,or $(2.57) and $(9.10) per basic and diluted share, respectively.

About Evelo Biosciences

Evelo Biosciences, Inc. is a clinical-stage biotechnology company developing monoclonal microbials, a potential new modality of oral biologic medicines. Evelo’s product candidates are single strains of microbes, selected for defined pharmacological properties. They are developed to activate multiple naturally evolved biological pathways by engaging immune cells that link the small intestine to the rest of the body. Evelo believes that monoclonal microbials have the potential to be broadly applicable across many immune-mediated diseases including inflammation, cancer and autoimmune diseases.

Evelo currently has three product candidates, EDP1066 and EDP1815 for the treatment of inflammatory diseases and EDP1503 for the treatment of cancer, for which ten clinical readouts are expected during 2019 and 2020. Evelo is also advancing additional candidates through preclinical development in other disease areas.
