Asthma Clinical Trial - Periostin-guided Withdrawal of Inhaled

Status Recruiting

Clinical Trial Summary

Background: Asthma is a common chronic condition characterized by respiratory symptoms and hyperresponsive airways. According to treatment guidelines, patients with persistent asthma require daily treatment with inhaled corticosteroids (ICS). However, certain subgroups of asthma patients such as non-eosinophilic asthma patients do not respond well to the ICS treatment. In the present study, asthma patients treated with ICS and exhibiting low levels of eosinophilic biomarkers such as S-periostin, FeNO and blood eosinophils, are randomized 1:1 to either 1) tapering of ICS or 2) usual care. Thus, the aim of the present study is to investigate whether patients with non-eosinophilic asthma can sustain their level of disease control during ICS tapering. Design: This is a randomized, controlled, one-center, non-inferiority study of ICS tapering in patients with non-eosinophilic asthma. Inclusion and exclusion criteria: 1) Objectively secured asthma diagnosis, 2) Age 18-65 years, 3) ICS treatment equivalent to Budesonide 800 microg daily or more with at least 80% adherence, 4) Serum-periostin < 50 ng/ml, 5) FeNO<25 ppb at all prior visits, 6) Blood-eosinophils<0.15 at screening, 7) no allergic asthma history, 8) no daily smoking within 6 months, 9) no other respiratory disease, 10) no daily treatment with immunosuppressives, 11) no pregnancy, and 12) no history of drug or alcohol abuse. Endpoints: Primary: Change in Control Questionnaire (ACQ) from baseline to post-tapered ICS and time from baseline to drop-out. Secondary: Change in FeNO, change in Serum-Periostin, change in FEV1, change in blood-eosinophils. Methods: Relevant patients will be recruited from Respiratory Outpatient Wards. In total, 110 patients will be required. Visits will be performed at screening, at week 0, 4, 8, 12, 16, 26, 52. In the active arm, ICS dosage will be reduced to 50% at week 0 and removed at week 8. All visits include ACQ, FeNO, spirometry, blood eosinophils. S-periostin will be measured at screening and at week 8 and 16.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
