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 (AD), a skin condition that causes red, itchy, and inflamed skin. The study is specifically for adolescents aged 12 to 18 years who have moderate-to-severe forms of this condition. The treatment being tested is called Rocatinlimab, also known by its code name AMG 451. This medication is given as a solution for injection under the skin.

The purpose of the study is to understand how safe and tolerable Rocatinlimab is for adolescents with moderate-to-severe Atopic Dermatitis. Participants in the study will receive the treatment over a period of 52 weeks. During this time, researchers will monitor the participants to see how they respond to the treatment and to check for any side effects. Some participants may receive a placebo, which is a substance with no active medication, to compare the effects of the treatment.

This study aims to provide valuable information about the safety and potential benefits of Rocatinlimab for young people dealing with this challenging skin condition. By participating, researchers hope to gather data that could lead to better treatment options for adolescents with Atopic Dermatitis in the future.

The research process

The trial runs in 5 steps – from screening to follow-up. Each step says what happens and what the team monitors.

  1. Step 1

    Initial visit

    Upon joining the study, you will attend an initial visit. During this visit, your eligibility for the trial will be confirmed based on specific criteria, such as age, weight, and the severity of your atopic dermatitis.

    You will receive information about the study, and your legally authorized representative will provide informed consent if you are under the legal age. You will also provide written assent if required.

  2. Step 2

    Screening assessments

    Screening assessments will be conducted to evaluate your condition. This includes measuring the extent of your atopic dermatitis and assessing your medical history.

    Your body surface area (BSA) affected by atopic dermatitis and your Eczema Area and Severity Index (EASI) score will be recorded.

  3. Step 3

    Treatment phase

    If eligible, you will enter the treatment phase, which lasts for 52 weeks. During this time, you will receive the medication rocatinlimab.

    The medication is administered as a solution for injection under the skin (subcutaneous use). The dosage and frequency will be explained to you by the study team.

  4. Step 4

    Regular follow-up visits

    Throughout the study, you will attend regular follow-up visits. These visits are important for monitoring your health and the effects of the medication.

    During these visits, you will undergo various assessments to check the safety and tolerability of the treatment.

  5. Step 5

    End of study visit

    At the end of the 52-week treatment period, you will have a final visit. This visit will include a comprehensive assessment of your condition and any changes observed during the study.

    The study team will discuss the results with you and provide guidance on the next steps for managing your atopic dermatitis.

Who can join the trial?

9 criteria

  • The person responsible for the patient must give permission for the patient to join the study if the patient is too young to decide for themselves. The patient must also agree in writing to participate.
  • The patient must have a vIGA-AD score of 3 or higher. This score measures the severity of the skin condition, with 3 being moderate and 4 being severe.
  • The patient must have at least 10% of their body surface area affected by the skin condition at the start of the study.
  • If the patient is receiving treatment for mental health issues, their treatment must be stable for at least 2 months before starting the study.
  • The patient must be between 12 and 17 years old.
  • The patient must have been diagnosed with Atopic Dermatitis (AD) for at least 6 months before joining the study.
  • The patient must weigh at least 40 kg (about 88 pounds) at the start of the study.
  • The patient must have previously tried a treatment called Topical Corticosteroids (TCS) of medium or higher strength and not had a good enough response. This means the treatment did not clear the skin or reduce the disease to a mild state, even after using it daily for at least 28 days or as recommended.
  • The patient must have an EASI score of 16 or higher. This score measures the extent and severity of the skin condition.

Who cannot join the trial?

8 criteria

  • Patients with any other skin conditions that might interfere with the study.
  • Patients who have had a serious allergic reaction to any medication in the past.
  • Patients who are currently participating in another clinical trial.
  • Patients who have used certain medications that might affect the study results.
  • Patients with a history of certain chronic diseases that could affect their safety during the study.
  • Patients who are pregnant or breastfeeding.
  • Patients who have a history of drug or alcohol abuse.
  • Patients with any condition that the study doctors believe would make it unsafe for them to participate.

This medication is designed to work by targeting specific parts of the immune system that are involved in causing the symptoms of atopic dermatitis. The goal of using rocatinlimab is to reduce the severity of the skin condition and improve the quality of life for those affected by it. In this clinical trial, researchers are focusing on understanding how safe and tolerable this medication is for adolescents, as well as how effective it is in managing their symptoms over a period of 52 weeks.

What is already known about the treatment

Rocatinlimab – Rocatinlimab is administered as an injection and is currently being studied in clinical trials for its safety and effectiveness in treating adolescents with moderate-to-severe atopic dermatitis, a chronic skin condition. This medication is still under investigation, and its use is not yet widely established in medical practice. Rocatinlimab works by targeting specific molecules in the immune system to reduce inflammation and alleviate symptoms of atopic dermatitis. It is classified as an immunomodulatory agent, which means it helps regulate the immune system's response.

Investigated diseases
