What is this trial about?

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

This study focuses on patients with asthma, comparing how the medication works in both adolescents and adults. The investigational treatment is CHF6001, which is administered as an inhalation powder using a special device called NEXThaler. The active substance in the medication is tanimilast.

The purpose of this research is to understand how CHF6001 is processed by the body in adolescents with asthma compared to adults with asthma. The study involves a single dose of the medication through inhalation. Both adolescent and adult participants must have stable asthma that has been treated with standard asthma medications for some time before joining the study.

During the study, participants will receive one dose of the study medication through inhalation. The researchers will take blood samples over time to measure how the medication moves through the body. They will also monitor heart activity, blood pressure, and check for any possible side effects. The study requires only a few visits to the study center, including a screening visit, a treatment day, and a follow-up visit.

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

    Initial study visit

    You will receive a single dose of CHF 6001 (3200 μg) using a device called NEXThaler

    The medication will be administered through inhalation (breathing in through the device)

    Before taking the medication, you will need to avoid using your regular asthma inhaler: short-acting inhalers for 6 hours, or long-acting inhalers for 24 hours

  2. Step 2

    Monitoring period - first 10 hours

    Your heart will be monitored through ECG measurements multiple times

    Your blood pressure will be checked at several points

    Blood samples will be collected to measure how the medication moves through your body

  3. Step 3

    Laboratory tests

    Blood tests will check standard health parameters

    Additional tests may be performed if deemed necessary by the medical staff

  4. Step 4

    Follow-up visit

    A final check of your health status will be conducted

    Any side effects that occurred during the study will be reviewed

    Final blood pressure and heart measurements will be taken

Investigated drugs

  • CHF 6001

    is an inhaled medication being studied for asthma treatment. It is administered using a device called NEXThaler®, which is an inhaler that delivers the medicine directly to the lungs. This medication is being investigated to understand how it works in both adolescent and adult patients with asthma.

  • NEXThaler®

    is a dry powder inhaler device used to deliver the medication to the lungs. It is designed to be easy to use and helps ensure that patients receive the correct amount of medicine with each inhalation.

What is already known about the treatment

CHF 6001 - An investigational inhaled medication administered via the NEXThaler® device, specifically being studied for the treatment of asthma. This drug is currently undergoing clinical trials to evaluate its pharmacokinetic profile in both adolescent and adult asthma patients. While the exact molecular mechanism is still under investigation, it belongs to the class of inhaled respiratory medications designed for asthma management. The 3200 μg dose delivered through oral inhalation represents a specific formulation being tested to determine its effectiveness and safety profile in different age groups of asthma patients.

Investigated diseases

Asthma - A chronic respiratory condition characterized by inflammation and narrowing of the airways. The condition causes recurring episodes where the airways become constricted, leading to breathing difficulties, wheezing, coughing, and chest tightness. During an asthma episode, the airway muscles tighten, the lining of the airways becomes swollen, and excess mucus is produced. The severity and frequency of symptoms can vary from person to person, with some experiencing mild occasional symptoms while others have more frequent episodes. Environmental triggers, such as allergens, exercise, or respiratory infections, can initiate or worsen asthma symptoms.
