CAMBRIDGE, Mass., Oct. 28, 2021 (GLOBE NEWSWIRE) — Evelo Biosciences, Inc. (Nasdaq:EVLO), a clinical stage biotechnology company developing SINTAX™ medicines as a new modality of orally delivered treatments for inflammatory disease, today reported financial results and business highlights for the third quarter 2021.

“This was a pivotal quarter for Evelo. We reported positive Phase 2 clinical data for EDP1815 that clearly demonstrate we can harness SINTAX™, the small intestinal axis, to drive meaningful clinical effects with an orally delivered medicine that had placebo-like safety and tolerability,” said Simba Gill, Ph.D., Chief Executive Officer of Evelo. “We are advancing EDP1815 towards registration trials in psoriasis whilst continuing to advance our broader platform and our pipeline. This includes a Phase 2 clinical trial for EDP1815 in atopic dermatitis and an ongoing clinical trial for EDP1867. Our recently announced preclinical data for EDP1867 shows the potential of EDP1867 beyond atopic diseases.”

Third Quarter 2021 Highlights and Recent Progress

EDP1815 Phase 2 Trial in Psoriasis

• In September 2021, Evelo
  
  announced
  
  positive data from its Phase 2 clinical trial evaluating EDP1815 versus placebo for the treatment of mild and moderate psoriasis.
• Data from Part B of the trial will be available 1Q 2022.
• Based on these data, Evelo intends to advance EDP1815 towards registration trials in psoriasis.
  

EDP1815 Phase 2 Trial in Atopic Dermatitis

• Based on the data from the EDP1815 Phase 2 trial in psoriasis and other external feedback, Evelo is modifying the endpoint of its EDP1815 Phase 2 trial in atopic dermatitis to extend the primary endpoint analysis period from 12 to 16 weeks and modifying it to be the percentage of patients achieving an EASI-50 (Eczema Area and Severity Index) score at week 16. As a consequence of this change, Evelo has increased the number of patients in the trial to 300, with a target of 225 on active and 75 on placebo.
• Evelo previously received and responded to a clinical hold letter from the U.S. Food and Drug Administration (FDA) related to its Investigational New Drug Application (IND) for the EDP1815 Phase 2 trial in atopic dermatitis. The FDA has lifted the clinical hold.
• Evelo anticipates reporting results from this trial in 4Q 2022.
  

EDP1815 in TACTIC-E, Phase 2/3 UK Platform Study for Hospitalized Patients with COVID-19

• Recruitment in TACTIC-E is progressing with the addition of clinical study sites in the UK, Brazil, India, and Mexico.
• Given the progress with TACTIC-E and the success of the vaccination program in the U.S., which has reduced hospitalization rates, Evelo will focus its efforts on the TACTIC-E trial and will close the smaller U.S. Phase 2 trial with Rutgers Robert Wood Johnson Medical School evaluating the safety and efficacy of EDP1815 for the treatment of hospitalized patients with newly diagnosed COVID-19.

EDP1867 for the Treatment of Neuroinflammatory Diseases

• In October 2021, Evelo
  
  presented
  
  preclinical data for EDP1867, a non-live pharmaceutical preparation of a single strain of
  
  Veillonella parvula
  
  , at the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS).
• In the preclinical study, EDP1867 was tested in a relapsing-remitting autoimmune encephalomyelitis (EAE) mouse model of neuroinflammation.
• Oral daily treatment with EDP1867 administered prophylactically or therapeutically reduced the severity of disease as demonstrated by a decreased mean maximum score and a decreased incidence of relapse compared to placebo.
• Treatment with EDP1867 reduced inflammation and demyelination in the spinal cord as shown in histopathological analysis.
• Transcriptional profiling of small intestine tissue confirmed that EDP1867 upregulated genes in lymphocyte pathways that resolve inflammation, as well as genes associated with intestinal homeostasis.
• Orally administered EDP1867 reduced disease severity and incidence of relapse in relapsing-remitting EAE mouse model of multiple sclerosis (MS), supporting the potential development of EDP1867 for the treatment of neuroinflammatory diseases.

Business Highlights

• In September 2021, Evelo
  
  announced
  
  the appointment of Professor Iain McInnes, M.B.Ch.B, Ph.D., to the Board of Directors.
• In September 2021, Evelo
  
  announced
  
  the issuance of a U.S. composition of matter patent for pharmaceutical compositions comprising
  
  Veillonella parvula
  
  bacteria, including EDP1867. EDP1867 is currently in clinical development for atopic dermatitis and preclinical development for neuroinflammatory diseases.

Upcoming Key Milestones

EDP1815 – Psoriasis

• Topline data from Part B of the Phase 2 trial assessing the durability of treatment response following completion of 16 weeks of dosing in 124 participants will report out in 1Q 2022.
• Evelo anticipates presenting the full Phase 2 data set at a medical meeting or scientific congress during 2022.

EDP1815 – Atopic Dermatitis

• Given that the FDA has lifted the clinical hold on the trial, Evelo anticipates enrolling the first patients in the Phase 2 trial during 4Q 2021.
• Data from Phase 2 trial anticipated in 4Q 2022.

EDP1867 – Atopic Dermatitis

• Interim data from Phase 1b trial anticipated in 1H 2022.
  

EDP2939 – Inflammation

• Initiation of clinical development in 2022.
  

EDP1908 – Oncology

• Initiation of clinical development in 2022.
  

Third Quarter 2021 Financial Results

• 
  Cash Position:
  
  As of September 30, 2021, cash and cash equivalents were $95.9 million, as compared to cash and cash equivalents of $68.9 million as of December 31, 2020.
• 
  Research and Development Expenses:
  
  R&D expenses were $22.6 million for the three months ended September 30, 2021, compared to $14.9 million for the three months ended September 30, 2020. The $7.7 million increase was primarily due to increased costs related to Evelo’s inflammation clinical development programs, personnel and R&D platform costs, partially offset by decrease in oncology program costs.
• 
  General and Administrative Expenses:
  
  G&A expenses were $10.1 million for the three months ended September 30, 2021, compared to $5.3 million for the three months ended September 30, 2020.
