Scientific title | Study of the effectiveness of voriconazole in the treatment of Aspergillus fumigatus associated asthma: a randomised double blinded, placebo controlled trial |
Study acronym | EVITA3 |
Study objectives | Voriconazole will be effective in eradicating colonisation of the airways by Aspergillus fumigatus (AF) in patients with Aspergillus fumigatus associated asthma (AFAA) and this will result in a prolonged improvement in their disease control. |
Ethics approval(s) | Leicestershire, Northamptonshire & Rutland Research Ethics Committee 2, REC No. 09/H0402/63 |
Health condition(s) or problem(s) studied | Asthma |
Intervention | 12 month randomised double-blind placebo-controlled parallel group trial to receive either placebo or voriconazole 200 mg twice daily orally for 12 weeks. |
Intervention type | Drug |
Pharmaceutical study type(s) | |
Phase | Not Applicable |
Drug / device / biological / vaccine name(s) | Voriconazole |
Primary outcome measure | The number of severe exacerbations over the 12 months of the study. |
Secondary outcome measures | 1. The percentage of patients whose sputum is no longer AF positive after three months of treatment with voriconazole and at the end of the study 2. The change in the sputum eosinophil count (measured as area under the curve) in the voriconazole versus the placebo group after three months of treatment and at the end of the study 3. The change in the total sputum neutrophil count (measured as area under the curve) in the voriconazole versus the placebo group after three months of treatment and at the end of the study 4. The change in forced expiratory volume in one second (FEV1) between the treatment and placebo group after treatment and at the end of the study 5. The number of courses of antibiotics between the treatment and placebo groups 6. The improvement in Juniper Asthma Control Questionnaire (JACQ) score at the end of the treatment and at the end of the study |
