Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.
|Eligible Ages||18 Years - 60 Years|
Inclusion Criteria:General: Participant has a body mass index of ≥ 18 kg/m2 to ≤ 35 kg/m2 at Screening. Healthy Volunteers: Participants who are overtly healthy as determined by medical evaluation including medical history, physical examination, laboratory tests, and cardiac monitoring. Mild to moderate psoriasis: 1. Participant has had a confirmed diagnosis of mild to moderate plaque-type psoriasis for at least 6 months involving ≤ 10% of body surface area (BSA) (excluding the scalp). 2. Participant has a minimum of 2 psoriatic lesions with at least 1 plaque in a site suitable for biopsy. Mild to moderate atopic dermatitis: 1. Mild to moderate atopic dermatitis with a minimum of 3% to a maximum of 15% BSA involvement. 2. Participant has had a confirmed diagnosis of mild to moderate atopic dermatitis for at least 6 months (IGA score of 2 or 3). 3. Participant has a minimum of 2 atopic dermatitis lesions with at least 1 in a site suitable for biopsy.
Exclusion Criteria:1. Female participant who is pregnant, or plans to become pregnant during the study, or breastfeeding, or sexually active with childbearing potential who is not using a medically accepted birth control method. 2. Participant has received live attenuated vaccination within 6 weeks prior to Screening or intends to have such a vaccination during the course of the study. 3. Participant has received any investigational drug or experimental procedure within 90 days or 5 half-lives, whichever is longer, prior to study intervention administration. 4. Participant requires treatment with an anti-inflammatory drug during the study period. Paracetamol will be permitted for use as an antipyretic and/or analgesic (maximum of 4 grams/day in any 24 hour period). 5. Participant has an active infection (e.g. sepsis, pneumonia, abscess) or has had an infection requiring antibiotic treatment within 6 weeks prior to Investigational Medicinal Product (IMP) administration. When in doubt, the investigator should confer with the Sponsor study physician. 6. Participant has renal or liver impairment, defined as: 1. 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 2. 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
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
The sponsor is the organization or person who oversees the clinical study and is responsible for analyzing the study data.

This will be a randomized, double-blind, placebo-controlled clinical study with dose escalations to assess safety, tolerability, and pharmacodynamic effect of EDP1815. 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 EDP1815 in this patient population provides an opportunity to gain pharmacodynamic information using a range of tissue biopsies and composite clinical endpoints.
