Study Overview
Brief Summary
A Multicentre, Randomized, Double-blind, Parallel Group, Placebo Controlled, Phase 3 Study to Evaluate the Efficacy and Safety of Tralokinumab in Reducing Oral Corticosteroid dependent Asthma.
Detailed Description
This is a randomized, double-blind, parallel group, placebo-controlled study designed to evaluate the efficacy and safety of a fixed 300 mg dose of tralokinumab administered subcutaneously every 2 weeks in adult and adolescent subjects with oral corticosteroid dependent asthma. Approximately120 subjects will be randomized globally. Subjects will receive tralokinumab or placebo, administered via subcutaneous injection at the study site, over a 40-week treatment period.

Outcomes
Primary Outcomes
Percent Change From Baseline in the Final Daily, Average, OCS Dose at Week 40 While Not Losing Asthma Control.
Time Frame: Baseline (Week 0) and Week 40
The 40-week treatment period consisted of 3 phases: an induction phase (Week 0 to Week 12) where patients remained on their optimised OCS dose; an OCS reduction phase (Week 12 to Week 32) where OCS dose reduction could have started at Week 12 with the possibility of dose titration every 4 weeks to reach the lowest possible OCS dose; and a maintenance phase (Week 32 to Week 40) where patients remained on the OCS dose reached at Week 32 to demonstrate asthma control was maintained after achieving the lowest OCS dose. Criteria used to assess asthma control included lung function assessments (forced expiratory volume in 1 second and morning peak expiratory flow), night awakenings, and the use of rescue medication and systemic corticosteroids. The least squares (LS) mean percent change from baseline in average daily OCS dose is presented. The final daily percent change from baseline was defined as {(Final daily average dose - baseline daily average dose)/baseline daily average dose}\*100%.
Secondary Outcomes
- The Number of Patients With Final Daily Average OCS Dose ≤5 mg at Week 40.(At Week 40)
- Annual Asthma Exacerbation Rate (AAER) up to Week 40.(Baseline (Week 0) up to Week 40)
- The Number of Patients With ≥50% Reduction in Final Average Daily OCS Dose at Week 40.(At Week 40)
