Modulate Systemic Inflammation-

        
CAMBRIDGE, Mass., August 6, 2019 - Evelo Biosciences, Inc. (Nasdaq:EVLO), a biotechnology company developing oral biologics that act on cells in the small intestine with systemic therapeutic effects, today announced positive interim Phase 1b clinical data and provided second quarter 2019 financial results.

"Evelo is harnessing the therapeutic potential of cells in the small intestine which play a central role in governing the immune, metabolic, and nervous systems. Our platform has generated a diversified portfolio of oral biologic candidates that act on these cells to drive systemic effects relevant to the potential treatment of a broad range of diseases," said Simba Gill, Ph.D., chief executive officer of Evelo. "Today’s positive interim data show, for the first time in patients, clinical and biomarker responses that support our core scientific hypothesis and our vision of developing effective, oral, safe, and affordable medicines for people with major chronic diseases and cancer. We look forward to advancing into later stage trials and continuing to expand our clinical portfolio."

Inflammation: Interim Clinical Data Highlights and Anticipated Milestones

About the EDP1815 and EDP1066 Phase 1b clinical trials
Each of EDP1815 and EDP1066 are in ongoing signal-finding Phase 1b clinical trials in mild to moderate psoriasis and atopic dermatitis. Patients in these trials are randomized 2:1 to receive daily, oral administration of active drug, or placebo, for 28 days. The primary endpoint of these trials is safety and tolerability. Prospectively defined secondary and exploratory endpoints include clinical measures of disease, cellular histological biomarkers and blood immune cell biomarkers taken from biopsies and blood samples, respectively, at the start and end of the 28-day dosing period.

EDP1815 - positive interim Phase 1b clinical data at low dose in mild to moderate psoriasis patients
In a separate press release this morning Evelo reported positive EDP1815 clinical data from an initial 12-patient cohort in its ongoing trial in mild to moderate psoriasis.
EDP1815 was well tolerated with no overall difference reported from placebo.
Patients dosed once per day for 28 days with 550mg (1x dose) of the enteric capsule formulation of EDP1815 showed a statistically significant (p>0.05) reduction in mean lesion severity score (LSS) at 28 days of 2 points, compared to a mean increase of 0.25 points in patients who received placebo. LSS reductions over the dosing period of patients dosed with EDP1815 ranged from 0-67 percent. LSS, a secondary endpoint, is a component of the Psoriasis Area and Severity Index (PASI) score and measures redness, thickness, and scaling of an individual psoriatic lesion across the dosing period and is a sensitive clinical measure for patients with mild to moderate disease.
Analysis of the basal epithelium mitotic count, a secondary endpoint and cellular driver of psoriasis pathology, showed a mean reduction over the dosing period of 2.25 cells/mm2 in patients who received EDP1815 compared to no change in patients receiving placebo. Lower basal epithelium mitotic counts indicate a reduction of psoriasis pathology.
In an analysis of the change over the dosing period of blood immune cell cytokine production following stimulation with lipopolysaccharide, an exploratory endpoint, the EDP1815 dosed patient group showed a reduction in cytokine production indicative of a systemic anti-inflammatory response, compared to no reduction in the placebo group.
Based on these data, Evelo plans to advance EDP1815 into Phase 2 in early 2020. This placebo-controlled dose and formulation optimization trial will investigate daily dosing of EDP1815 in mild to moderate psoriasis patients over 24 weeks.
Enrollment is underway in the ongoing Phase 1b clinical trial of an additional cohort of mild to moderate psoriasis patients to be dosed at a 2.76g (5x) dose of the enteric capsule formulation. Data from this cohort are expected in the fourth quarter of 2019.






EDP1066 - positive interim Phase 1b biomarker data at high dose in mild to moderate psoriasis patients
Today, Evelo reports positive EDP1066 biomarker data at the high dose from its ongoing Phase 1b trial in patients with mild to moderate psoriasis.
EDP1066 was well tolerated with no overall difference reported from placebo.
In an analysis of the change over the dosing period of blood immune cell cytokine production following stimulation by lipopolysaccharide, an exploratory endpoint, patients who received a 3.3g (5x) dose of EDP1066 showed a reduction in cytokine production consistent with a pharmacodynamic effect. No reduction was observed in patients receiving a 660mg (1x) dose of EDP1066 or placebo.
No effects were observed in the secondary endpoints of clinical measures of disease or cellular histological biomarkers at either the 660mg or 3.3g dose of EDP1066.
Evelo is focusing the current EDP1066 Phase 1b trial on investigating the activity of a new formulation, which was up to 30-fold more potent in preclinical models, in a cohort of mild to moderate atopic dermatitis patients. Evelo expects to report data from this cohort in the first quarter of 2020.
Given the EDP1815 data, Evelo will not develop EDP1066 any further in psoriasis.

Oncology: Clinical Studies and Anticipated Milestones

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. Evelo will no longer be providing guidance as to timing related to this investigator-sponsored trial.

Business Highlights
In June 2019, Evelo appointed Jose-Carlos Gutiérrez-Ramos, Ph.D. to its board of directors. Dr. Gutiérrez-Ramos brings to the board significant experience in research, clinical development and company building over a long career in senior leadership roles at major pharmaceutical and biotech companies. Dr. Gutiérrez-Ramos has served as chief executive officer and president of Cogen Immune Medicine, Inc., a biotechnology company, since August 2018. Dr. Gutiérrez-Ramos has also served as a venture partner at Flagship Pioneering since 2018. From 2015 to May 2018 he served as chief executive officer and president of Synlogic, Inc. Prior to joining Synlogic, Dr. Gutiérrez-Ramos was group senior vice president of Worldwide Research and Development and global head of Biotherapeutics Research and Development at Pfizer, Inc. Dr. Gutiérrez-Ramos received a B.S. from Universidad Complutense de Madrid and his Ph.D. in immunochemistry from the Universidad Autonoma de Madrid.
In July 2019, Evelo entered into a loan and security agreement with K2 HealthVentures (K2HV). Under the terms of the agreement, Evelo can borrow up to $45 million subject to certain time conditions and clinical development milestones. On closing, Evelo borrowed $20 million; the funds were used to fully repay its $15 million loan facility with Pacific Western Bank and for general corporate purposes.
In July 2019, Evelo entered into a collaboration agreement with Sacco S.r.l. (Sacco), an existing contract manufacturing partner. Under the terms of this 5-year agreement, Sacco will manufacture and supply single strain, non-genetically modified microbes for oral delivery or oral use in pharmaceutical products exclusively for Evelo, with the exception of pre-existing products for pre-existing customers. This collaboration is consistent with Evelo’s manufacturing strategy of combining best-in-class manufacturing partners with internal manufacturing capacity and deep internal expertise in process development and formulation.

Second Quarter 2019 Financial Results
Cash Position: As of June 30, 2019, cash, cash equivalents and investments were $113.5 million, as compared to $178.9 million as of June 30, 2018 and $129.4 million as of March 31, 2019. This decrease was due to cash used to fund operating activities and capital expenditures. Evelo expects that its cash, cash equivalents and investments will enable it to fund its planned operating expenses and capital expenditure requirements, including the planned EDP1815 Phase 2 clinical trial, into the fourth quarter of 2020.






Research and Development Expenses: R&D expenses were $15.5 million for the three months ended June 30, 2019, compared to $10.2 million for the three months ended June 30, 2018. The increase of $5.3 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 $5.9 million for the three months ended June 30, 2019, compared to $5.1 million for the three months ended June 30, 2018. The increase of $0.8 million was due primarily to increased personnel costs and professional and consulting fees necessary to support Evelo’s growing organization and corporate operational activities.
Net Loss: Net loss attributable to common stockholders was $20.9 million for the three months ended June 30, 2019, or $(0.65) per basic and diluted share, as compared to a net loss attributable to common stockholders of $16.7 million for the three months ended June 30, 2018, or $(0.85) per basic and diluted share.

CAMBRIDGE, Mass., August 6, 2019 - Evelo Biosciences, Inc. (Nasdaq: EVLO), a biotechnology company developing oral biologics that act on cells in the small intestine with systemic therapeutic effects, today announced positive interim clinical data from the first cohort of patients with mild to moderate psoriasis from its ongoing Phase 1b trial of EDP1815, its clinical candidate for the treatment of inflammatory diseases. EDP1815 was well tolerated with no overall difference reported from placebo.

12 patients with mild to moderate psoriasis were randomized 2:1 to receive daily, oral administration of 550mg (1x dose) of EDP1815, or placebo, for 28 days. The primary endpoint was safety and tolerability. Secondary and exploratory endpoints included lesion severity score (LSS), a measure of clinical activity, cellular histological biomarkers and blood immune cell biomarkers taken from biopsies and blood samples, respectively, at the start and end of the 28-day dosing period.

Patients dosed daily for 28 days with 550mg of the enteric capsule formulation of EDP1815 showed a statistically significant (p<0.05) reduction in mean LSS at 28 days of 2 points, compared to a mean increase of 0.25 points in patients who received placebo. Data from patients dosed with EDP1815 showed a reduction in LSS over the dosing period ranging from 0 to 67 percent. LSS, a secondary endpoint, is a component of the Psoriasis Area and Severity Index (PASI) score and measures redness, thickness, and scaling of an individual psoriatic lesion across the dosing period and is a sensitive clinical measure for patients with mild to moderate disease.

Analysis of the change over the dosing period of the basal epithelium mitotic count, a secondary endpoint and a cellular driver of psoriasis pathology, showed a mean reduction of 2.25 cells/mm2 in patients who received EDP1815 compared to no change in patients receiving placebo. Lower basal epithelium mitotic counts indicate a reduction of psoriasis pathology.

In an analysis of blood immune cell cytokine production following stimulation with lipopolysaccharide, an exploratory endpoint, the EDP1815 dosed patient group showed a reduction in cytokine production indicative of a systemic anti-inflammatory response, compared to no reduction in the placebo group.

Evelo plans to advance EDP1815 into Phase 2 in early 2020. This trial will investigate daily dosing of EDP1815 in mild to moderate psoriasis patients over 24 weeks. Multiple doses and formulations of EDP1815 will be investigated.

"We believe these first-in-human data support our core scientific thesis that oral biologics that target cells in the small intestine can drive systemic immune effects," said Duncan McHale, M.B.B.S., Ph.D., chief medical officer of Evelo. "The results we have observed on the lesion severity score, a component of the PASI score, and biomarkers of disease at the low dose of EDP1815 over a short dosing duration support the potential of our platform to identify oral biologics that modulate the immune system. We look forward to advancing EDP1815 into Phase 2 in psoriasis in early 2020 and studying it in other inflammatory diseases."

About the EDP1815-101 Clinical Trial
EDP1815-101 is a double-blind placebo-controlled Phase 1b trial designed to evaluate the safety and tolerability of EDP1815 in approximately 108 healthy volunteers and patients with mild or moderate psoriasis or atopic dermatitis. Prospectively defined secondary and exploratory endpoints include the effect of EDP1815 on clinical measures of disease and a range of biomarkers. Enrollment is underway in a cohort of mild to moderate psoriasis patients to be dosed with 2.76g (5x dose) of the enteric capsule formulation. One further cohort of psoriasis patients and one cohort of atopic dermatitis patients are planned to be dosed with a new formulation of EDP1815.






Evelo expects to present data from this initial cohort at a future scientific conference or medical meeting.

About the EDP1815 Phase 2 Clinical Trial
Evelo plans to advance EDP1815 into Phase 2 in early 2020. This trial is designed to investigate daily dosing of EDP1815 in mild to moderate psoriasis. The primary endpoint of the trial is expected to be reduction in the PASI score over 24 weeks, with an interim analysis at 12 weeks. Multiple doses and formulations of EDP1815 will be investigated. Part A of the trial is designed to select the optimal formulation and will test the enteric capsule formulation and the new formulation of EDP1815 versus placebo in approximately 180 patients. Evelo expects to report interim data from Part A of the study and select the optimal formulation for Part B of the study in late 2020. Part B of the study will test multiple doses of the optimal formulation against placebo for 24 weeks in approximately 250 patients.

About EDP1815
EDP1815 is an investigational orally delivered monoclonal microbial being developed for the treatment of inflammatory diseases. EDP1815 is a strain of Prevotella histicola, selected for its specific pharmacology. In preclinical studies EDP1815 has shown potent immunomodulatory effects on human immune cells in vitro and in vivo anti-inflammatory activity on a range of tissues, including skin, joints, gut, and the CNS.

Key Highlights • Interim clinical data supports Evelo’s platform opportunity and vision • EDP1815 and EDP1066 were well tolerated • EDP1815 in psoriasis • Reduction in mean Lesion Severity Score vs. placebo • Consistent skin and blood immune cell biomarker responses • Advancing into Phase 2 in early 2020 • EDP1066 in psoriasis • Pharmacodynamic responses on blood immune cell biomarkers at high dose • No further development in psoriasis • Investigating more potent formulation in atopic dermatitis patients in ongoing study 3


 
EDP1815 in Psoriasis 4


 
Targeting EDP1815 to Address Unmet Needs of Psoriasis Patients Mild Moderate Severe 71% 22% 7% • Future opportunity to treat any stage of disease given differentiated profile of Evelo’s oral biologics • Initial focus on mild to moderate populations with potential to address over 3.5 millionof these patients in US and EU5 and expand globally (2018 company-sponsored market research; EU consisting of France, Germany, Italy, Spain and the UK 5


 
EDP1815 Low Dose Psoriasis Cohort • 12 patients with mild to moderate psoriasis • Randomized 2:1 (active:placebo) with 550mg dose (enteric capsule formulation) for 28 days; daily oral administration • Primary endpoint of safety and tolerability • EDP1815 was well tolerated with no overall difference reported from placebo • Signal finding study, low dose and short duration of dosing 6


 
Secondary and Exploratory Endpoints Reported • Lesion Severity Score • Cellular biomarkers from skin biopsies • Blood immune cell biomarkers of cytokine production 7


 
Lesion Severity Score is a Sensitive Clinical Measure • Clinical measure of disease change in psoriasis • Lesion Severity Score is a component of the PASI scoring system • Uses the same underlying changes as lesion severity element of the PASI score • Tracks an individual lesion across dosing period • Measures redness, thickness and scaling on a 12-point scale • Sensitive short-term measure in patients with mild to moderate disease 8


 
Statistically Significant Reduction in Lesion Severity Score Mean change (+/- SE) in lesion severity score over dosing period 9


 
Patient Data Showed Reduction in Lesion Severity Score of 0-67% 25% 0% Percent change in Group lesion severity score at −25% Placebo end of dosing period EDP1815 −50% −75% 1 2 3 4 5 6 7 8 9 10 11 12 ID 10


 
Reductions in Skin Cellular Biomarkers were Consistent with Improvement in Lesion Severity Score • Psoriasis pathology is driven by epithelial hyperplasia • Reductions observed in basal Mean (+/- SE) change in basal epithelium mitotic epithelium mitotic counts across cell count over dosing period (cells/mm2) patients dosed with EDP1815 11


 
Reduction in Blood Immune Cell Cytokine Production Indicative of a Systemic Anti-inflammatory Response Changes over Dosing Period in Cytokine Production After Stimulation of Blood Immune Cells with Lipopolysaccharide • Reduction in systemic cytokine Increased Production Increased production consistent with clinical signal and histological biomarkers • No reduction observed in placebo Decreased production Decreased Cytokines detected: IL10, IL8, TNFα, IL6, IL1B, IFN-γ Decrease or increase in cytokine production defined as a change of 2 pg/ml over dosing period 12


 
Positive Interim Data for 1st Cohort with Low Dose Over 28 Days Supports Advancing into Phase 2 • EDP1815 was well tolerated with no overall difference reported from placebo • Statistically significant reduction vs. placebo in Lesion Severity Score • Reduction in Lesion Severity Score of 0-67% in patients dosed with EDP1815 • Cellular biomarker changes consistent with reduction in Lesion Severity Score • Reduction in blood immune cell cytokine production indicative of a systemic anti- inflammatory response 13


 
Planning for EDP1815 Phase 2 and Indication Expansion Placebo-controlled dose and formulation optimization study in mild to moderate psoriasis patients planned for early 2020 initiation • Primary endpoint: change in PASI score at 24 weeks • Interim analysis at 12 weeks Part A Part B Goal: Formulation selection Goal: Dose selection n~180, 3 arms, original formulation vs. n~250, 4 arms, 3 different doses of optimal new formulation vs. placebo formulation vs. placebo Opportunity to expand into additional diseases following Part A interim analysis 14


 
Novel Formulation was Up to 30-fold More Potent Preclinically 15


 
EDP1066 in Psoriasis 16


 
Dose-dependent Response Observed on Blood Immune Cell Cytokine Production in Phase 1b Clinical Trial • EDP1066 was well tolerated with no overall difference reported from placebo • Reduction in blood immune cell cytokines which indicates a pharmacodynamic response in patients at the high dose; no effect at low dose • Evidence that EDP1066 may modulate systemic immunology • No effects observed on cellular biomarkers or clinical measures of disease at either dose 17


 
Reduction in Blood Immune Cell Cytokine Production Indicate a Pharmacodynamic Response at High Dose Changes over Dosing Period in Cytokine Production After Stimulation of Blood Immune Cells with Lipopolysaccharide • 3.3g EDP1066 dose group caused a Increased Production Increased decreased production of cytokines • No reduction observed in patients receiving the 660mg dose of EDP1066 or placebo Decreased production Decreased Cytokines detected: IL10, IL8, TNFα, IL6, IL1B, IFN-γ Decrease or increase in cytokine production defined as a change of 2 pg/ml over dosing period 18


 
Next Steps for EDP1066 • Focusing current Phase 1b trial on investigating activity of new formulation in atopic dermatitis • Data from 24 patient atopic dermatitis cohort with new formulation expected early 2020 • No further development in psoriasis 19
