CAMBRIDGE, Mass., May 02, 2019 (GLOBE NEWSWIRE) -- Evelo Biosciences, Inc. (Nasdaq: EVLO) ("Evelo"), a clinical stage biotechnology company developing oral biologics that act on cells in the small intestine with striking therapeutic effects throughout the body, today reported financial results and provided a business update for the first quarter of 2019.

"We continue to progress therapies targeting cells in the small intestine to drive systemic effects to treat major diseases. We look forward to clinical data from our first inflammatory disease trial of EDP1066 in healthy volunteers and psoriasis patients early in the third quarter and in atopic dermatitis patients shortly thereafter," said Simba Gill, Ph.D., chief executive officer of Evelo. "In addition, we have discovered novel formulations of monoclonal microbials which significantly improve potency in preclinical models. In parallel with completion of the current patient cohorts, we are advancing a novel formulation into our ongoing clinical studies, providing us with the opportunity for additional clinical readouts in the near term."

Business Highlights:

Platform Discovery: Novel Formulations with Increased Potency

• Evelo has discovered a new formulation that enhances the pharmacological potency of monoclonal microbials by up to 30-fold in preclinical in vivo models.
• This proprietary formulation enhances the probability of translating preclinical effects into patients and can be commercialized cost effectively.
• Evelo plans to introduce this formulation into ongoing and new clinical trials beginning in the second half of 2019 across multiple monoclonal microbials.
• Evelo continues to invest in enhanced forms and formulations of oral biologics.

Ongoing Clinical Studies and Anticipated Milestones

Inflammation:

EDP1066 - Phase 1b

• Healthy volunteers and psoriasis patients - Evelo expects to complete dosing this quarter and to report initial clinical data early in the third quarter of 2019.
• Atopic dermatitis patients - Following the recent addition of a new cohort of patients, Evelo expects to report initial clinical data in the third quarter of 2019.
• New formulation - Evelo expects to report initial clinical data from cohorts of psoriasis and atopic dermatitis patients during the fourth quarter of 2019 and the first quarter of 2020, respectively.

EDP1815 - Phase 1b

• Evelo completed dosing of EDP1815 in two dose-ascending healthy volunteer cohorts. Based on the data reviewed by the trial’s safety committee, the trial proceeded as planned into patients.
• Following the addition of a new formulation into the trial, Evelo expects to report initial clinical data from psoriasis and atopic dermatitis patients in early 2020.

Anticipated Additional Studies

• Evelo expects to continue to conduct immuno-pharmacology studies in healthy volunteers with EDP1066 and EDP1815 to explore additional doses and formulations.
• Subject to data from ongoing trials, Evelo expects to initiate clinical trials in additional inflammatory disease indications in the second half of 2019.

Oncology:

EDP1503 - Phase 1/2

• Evelo is conducting a Phase 1/2 clinical trial of EDP1503 in combination with KEYTRUDA® (pembrolizumab), Merck’s anti-PD-1 therapy, 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. Initial clinical data is expected in the first half of 2020.

EDP1503 - Phase 2a

• The University of Chicago is conducting a Phase 2a investigator-sponsored clinical trial of EDP1503 in combination with KEYTRUDA in naive melanoma patients and melanoma patients who have relapsed on prior PD-1/L1 inhibitor treatment. Initial clinical data expected in second half of 2020.

First Quarter 2019 Financial Results

• Cash Position: As of March 31, 2019, cash, cash equivalents and investments were $129.4 million, as compared to cash and cash equivalents of $147.9 million as of December 31, 2018. This decrease was due to cash used to fund operating activities and capital expenditures for the first quarter of 2019. 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 $15.7 million for the three months ended March 31, 2019, compared to $7.1 million for the three months ended March 31, 2018. The increase of $8.6 million was due primarily to increases in costs related to Evelo’s inflammation and oncology clinical development programs, and research platform expenses, as well as increased personnel costs.
   
• General and Administrative Expenses: G&A expenses were $5.1 million for the three months ended March 31, 2019, compared to $3.3 million for the three months ended March 31, 2018. The increase of $1.8 million was due primarily to increased general and administrative personnel costs, professional and consulting fees, and facility expenses supporting Evelo’s growing R&D organization and public company infrastructure.
   
• Net Loss Attributable to Common Stockholders: Net loss attributable to common stockholders was $20.3 million for the three months ended March 31, 2019, or $(0.64) per basic and diluted share, as compared to a net loss attributable to common stockholders of $12.9 million for the three months ended March 31, 2018, or $(3.29) per basic and diluted share.

About Evelo Biosciences

Evelo Biosciences, Inc. is a clinical stage biotechnology company developing oral biologics that act on cells in the small intestine with striking therapeutic effects throughout the body. These cells in the small intestine play a central role in governing the immune, metabolic and neurological systems. The company’s first product candidates are monoclonal microbials, single strains of microbes selected for defined pharmacological properties. They have systemic dose-dependent effects, modulating multiple clinically validated pathways. Evelo’s therapies have the potential to be effective, safe and affordable medicines to improve the lives of people with chronic disease and cancer.

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 oral biologics through preclinical development in other disease areas.
