A Study of EDP1066 in Healthy Participants and Participants With Mild to Moderate Psoriasis and Atopic Dermatitis
- Conditions
- Atopic DermatitisPsoriasis
- Interventions
- Other: EDP1066Drug: Placebo oral capsule
- Registration Number
- NCT03542994
- Lead Sponsor
- Evelo Biosciences, Inc.
- Brief Summary
Evelo will investigate the safety and tolerability of EDP1066 and its potential to be a medicinal product in healthy volunteers and individuals with mild to moderate psoriasis and atopic dermatitis.
- Detailed Description
This will be a randomized, double-blind, placebo-controlled clinical study with dose escalations to assess safety, tolerability, and pharmacodynamic effect of EDP1066. Since this clinical study is the first study in humans, the participants will be healthy volunteers or subjects with mild to moderate psoriasis or atopic dermatitis who are otherwise well. Investigation of EDP1066 in this patient population provides an opportunity to gain pharmacodynamic information using a range of tissue biopsies and composite clinical endpoints.

-
Participant has renal or liver impairment, defined as:
a. For healthy volunteers: i. For women, serum creatinine level ≥ 125 μmol/L; for men, ≥ 135 μmol/L, or ii. Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≥ 1.5 x upper limit of normal (ULN), or iii. Alkaline phosphatase (ALP) and/or bilirubin > 1.5 x ULN b. For participants with mild to moderate atopic dermatitis or psoriasis: i. For women, serum creatinine level ≥ 125 μmol/L; for men, ≥ 135 μmol/L, or ii. ALT or AST > 2 x ULN and/or bilirubin > 1.5 x ULN

Safety and tolerability measured through lab measurements Day 0 to Day 60 Number of participants with clinically significant change from baseline (Day 0) in laboratory values
Safety and tolerability measured through ECG Day 0 to Day 60 Number of participants with clinically relevant changes from baseline (Day 0) ECG parameters
Safety and tolerability measured through physical examination Day 1 to Day 60 Physical examination of stool samples based on the Bristol Stool Scale (Types 3 and 4 are ideal stool):
Type 1: Separate hard lumps, like nuts (hard to pass); Type 2: Sausage-shaped, but lumpy; Type 3: Like a sausage but with cracks on its surface; Type 4: Like a sausage or snake, smooth and soft; Type 5: Soft blobs with clear cut edges (easy to pass); Type 6: Fluffy pieces with ragged edges, a mushy stool; Type 7: Watery, no solid pieces, entirely liquidGI safety measurement through biomarker analysis Day 1 to Day 60 GI safety measurement through fecal calprotectin analysis
- Secondary Outcome Measures
Name Time Method Clinical improvement in subjects with mild to moderate psoriasis Day 0 to Day 60 Change from baseline (Day 0) Psoriasis-area-and-severity index score (PASI) in response to EDP1066, measured on a scale of 0 to 6 (where 0 is most favorable and 6 is least favorable).
