AI summary: who the study is looking for
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for adults with moderate or severe asthma, who take regular asthma medicines, to test the drug WIN378 against placebo.
- Age
- 18 to 75 years
- Sex
- All sexes can join. Women who can have children must use a highly effective contraception method.
- Disease stage
- Doctor-diagnosed asthma with proof of reversible airway narrowing. Part A: moderate to severe asthma. Part B: severe asthma that is not well controlled, with at least 2 asthma attacks (exacerbations) in the past 12 months.
- Earlier treatment
- Must already take inhaled steroids (ICS) plus at least 1 other regular asthma medicine (LABA/LTRA/LAMA/chromones/theophylline). Part A: low, medium or high dose ICS. Part B: medium or high dose ICS.
- Biomarker or test result
- Lung function test: pre-BD FEV1 of 30% to 90% of predicted in Part A, and 30% to 80% of predicted in Part B.
Main reasons for not taking part
- Another important lung disease besides asthma
- Tuberculosis, or tuberculosis treatment within the past 12 months
- Current or former smoker with 10 pack years or more

A Phase 2 Randomized, Double-blind Placebo-Controlled Study to Evaluate the Pharmacokinetics, Immunogenicity, Safety and Efficacy of WIN378 in Adult Participants With Moderate or Severe Asthma
This is a global Phase 2 study divided in two parts. Part A is a double-blind, randomized dose-range finding study in adults with moderate to severe asthma to confirm the dosing regimen of WIN378 that can be tested in future pivotal trials for efficacy and safety.
Part B is a pivotal double-blind, randomized study to demonstrate the efficacy and safety of WIN378 in adults with severe uncontrolled asthma. Two dose levels of WIN378 will be tested against placebo to evaluate AAER, lung function, asthma control, asthma-related quality of life and other important efficacy endpoints.
Inclusion: Written Informed Consent Form; Females that are not pregnant or breastfeeding with following condition: not a woman of childbearing potential or woman of childbearing potential using a highly effective contraception method; Physician-diagnosis of asthma and documented evidence of airway reversibility during prior 24 months or during screening; Airflow limitation as indicated by pre-BD FEV1 value: PART A of ≥ 30% and ≤ 90%, predicted; PART B of ≥ 30% and ≤ 80%, predicted; PART A Low, medium-, or high-dose ICS and ≥1 maintenance asthma controller medication (LABA/LTRA/LAMA/chromones/theophylline); PART B: medium-, or high-dose ICS and ≥1 maintenance asthma controller medication (LABA/LTRA/LAMA/chromones/theophylline); Part B: History of at least of 2 asthma exacerbations within 12 months before V1.
Exclusion: Receipt of any marketed biologic agent within 4 months or 5 half-lives prior to screening; Receipt of immunoglobulin or blood products within 30 days prior to screening or during the Screening Run-in period; Receipt of any live or attenuated vaccines within 15 days prior to screening; Helminth infection within 24 weeks prior to screening; Use of immunosuppressive medication within 3 months prior to Screening Visit or during the Screening Run-in period; Participants with a known, pre-existing, clinically important lung condition other than asthma; Tuberculosis or treatment required for tuberculosis within 12 months; History of cancer; Current or former smokers ≥10 pack years; Participants who are pregnant, lactating or breastfeeding.
