About this study

Official title: A Phase 1 Randomized Double-Blind Placebo-controlled Single and Multiple Ascending Dose Study of EDP1815 in Healthy Participants and Participants With Mild to Moderate Psoriasis or Atopic Dermatitis

Evelo will investigate the safety and tolerability of EDP1815 and its potential to be a medicinal product in healthy volunteers and individuals with mild to moderate psoriasis and atopic dermatitis.

Read the detailed description

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.

Being tested
EDP1815, Placebo oral capsule, Placebo oral tablet
Medical subject headings
Psoriasis, Dermatitis, Atopic

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Safety and tolerability measured through Adverse Events (AEs)

    Number of participants with AEs by seriousness and relationship to treatment

    Measured: Day 1 to Day 70

  2. Safety and tolerability measured through lab measurements

    Number of participants with clinically significant change from baseline (Day 0) in laboratory values

    Measured: Day 0 to Day 70

  3. Safety and tolerability measured through ECG

    Number of participants with clinically relevant changes from baseline (Day 0) ECG parameters

    Measured: Day 0 to Day 70

  4. Safety and tolerability measured through physical examination

    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 liquid

    Measured: Day 0 to Day 60

  5. GI safety measurement through biomarker analysis

    GI safety measurement through fecal calprotectin analysis

    Measured: Day 0 to Day 60

Secondary outcomes (2)
  1. Clinical improvement in subjects with mild to moderate psoriasis

    Change from baseline (Day 0) Psoriasis-area-and-severity index score (PASI) in response to EDP1815, measured on a scale of 0 to 6 (where 0 is most favorable and 6 is least favorable).

    Measured: Day 0 to Day 70

  2. Clinical improvement in subjects with mild to moderate atopic dermatitis

    Change from baseline (Day 0) Eczema-area-and-severity index score (EASI) in response to EDP1815, measured on a scale of 0 to 6 (where 0 is most favorable and 6 is least favorable).

    Measured: Day 0 to Day 70

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing EDP1815 in people with Psoriasis and Atopic Dermatitis, run by Evelo Biosciences, Inc. at 9 sites in United Kingdom.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 11 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 10 Jan 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 9 sites in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Safety and tolerability measured through Adverse Events (AEs) (time frame: Day 1 to Day 70). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03733353, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Jan 2022.
