Open-label Study to Assess Reduction of Background Asthma Medication While Sustaining Asthma Control and Clinical Remission With Tezepelumab in Patients 12-80yrs With Severe Asthma.
brief summary
The objective of this study is to assess the potential for tezepelumab-treated patients (subcutaneous administration) to reduce maintenance therapy without loss of asthma control in adolescent and adults with severe asthma.. Study details include: 1. The study duration will be up to 72 weeks. 2. The treatment duration will be up to 68 weeks. 3. The visit frequency will be once every 4 weeks (Q4W).
detailed description
This is a multicentre, randomised, open-label, parallel-group, phase IIIb study to assess the potential for tezepelumab-treated patients to (1) reduce maintenance therapy without the loss of asthma control at Week 56, among those who demonstrated asthma control or low biomarkers at Week 24, and (2) be in asthma control and have characteristics of clinical remission at Week 24.
Approximately 65 sites in 10 countries will enrol adult and adolescent patients with severe uncontrolled asthma.
The study is divided into 5 phases as described below:
* Screening/Run-in Phase (from Week -4 until Week 0, up to 4 Weeks) * Treatment Induction Phase (Week 0 to Week 4) * Treatment Continuation Phase (Week 4 to Week 24) * Tezepelumab Treatment With or Without ICS Step-down Therapy Phase (Week 24 to Week 56) * Maintenance Phase (Week 56 to Week 72)
