What is this trial about?

A plain-language summary of the goals, design and what participants do

This clinical trial is focused on studying atopic dermatitis, a condition that causes the skin to become red, itchy, and inflamed. The trial will evaluate a new treatment called BP1.7881, which is a film-coated tablet taken by mouth. BP1.7881 is a type of medication known as a dual histamine H1 and H4 receptor antagonist, which means it works by blocking certain substances in the body that can cause allergic reactions and inflammation.

The purpose of the study is to assess the safety and effectiveness of BP1.7881 in adults with moderate-to-severe atopic dermatitis. Participants in the trial will be randomly assigned to receive either the BP1.7881 tablet or a matching placebo tablet, which looks like the real medication but does not contain the active ingredient. The study will last for 12 weeks, during which participants will take the tablets and attend regular check-ups to monitor their condition and any changes in their symptoms.

Throughout the trial, researchers will be looking at various outcomes, such as changes in the severity of the skin condition and the level of itching experienced by participants. The goal is to determine whether BP1.7881 can provide significant relief from the symptoms of atopic dermatitis compared to the placebo. This study is important for understanding how well BP1.7881 works and ensuring it is safe for people with this skin condition.

The research process

The trial runs in 4 steps – from screening to follow-up. Each step says what happens and what the team monitors.

  1. Step 1

    Randomization and start of treatment

    Upon joining the trial, you will be randomly assigned to one of two groups. One group will receive the investigational medication BP1.7881, and the other group will receive a placebo, which looks like the medication but does not contain the active ingredient.

    You will take the assigned tablet orally as a film-coated tablet once daily for a duration of 12 weeks.

  2. Step 2

    Regular check-ups and assessments

    Throughout the 12-week period, you will attend regular check-ups. These visits are important to monitor your health and the effects of the treatment.

    During these visits, your skin condition will be assessed using the Eczema Area Severity Index (EASI) and the Investigator's Global Assessment (IGA). These are tools used to measure the severity of your atopic dermatitis.

  3. Step 3

    Completion of treatment

    At the end of the 12-week treatment period, you will have a final assessment to evaluate the changes in your skin condition.

    The primary goal is to measure the mean change in your EASI score from the start to the end of the trial. Secondary goals include assessing improvements in your IGA score and the intensity of itchiness using the Pruritus Numerical Rating Scale (NRS).

  4. Step 4

    Post-treatment follow-up

    After completing the treatment, you may be asked to attend follow-up visits to monitor any lasting effects of the treatment.

    Male participants are required to continue using reliable contraception methods for 90 days after the last dose of the study drug.

Investigated diseases

Atopic dermatitis – Atopic dermatitis is a chronic inflammatory skin condition characterized by dry, itchy, and red skin. It often begins in childhood but can occur at any age. The disease progresses through periods of flare-ups and remissions, where symptoms can worsen and then improve. During flare-ups, the skin may become more inflamed, leading to increased itching and discomfort. Over time, repeated scratching can cause the skin to thicken and become more susceptible to infections. The condition is associated with a compromised skin barrier and an overactive immune response.
