- 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%.
- The Number of Patients With Final Daily Average OCS Dose ≤5 mg at Week 40. [ Time Frame: At 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.
The number of patients with a final daily average OCS dose ≤5.0 mg is presented. For patients prescribed a fixed daily dose, then the average OCS dose was defined as the prescribed dose. For patients on a regimen where a different amount of OCS was to be taken each day, then the average OCS dose was defined as the average amount prescribed to be taken each day.
- The Number of Patients With ≥50% Reduction in Final Average Daily OCS Dose at Week 40. [ Time Frame: At 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.
The number of patients with ≥50% reduction 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%. If this resulted in a value of -50% or less (more negative), that patient was classified as having at least a 50% reduction in final daily average OCS dose.
- Annual Asthma Exacerbation Rate (AAER) up to Week 40. [ Time Frame: Baseline (Week 0) up to Week 40 ]
AAER up to Week 40 in the tralokinumab group was compared to that seen in the placebo group. The response variable was the number of exacerbations the patient experienced up to Week 40, with the logarithm of the time at risk in years of experiencing an exacerbation included as offset in the model.
AAER = number of exacerbations*365.25/(follow-up date - date of randomisation + 1).
Asthma exacerbation was defined as a worsening of asthma that led to any of the following:
- Use of systemic corticosteroids for at least 3 days; a single depo-injectable dose of corticosteroids was considered equivalent to a 3-day course of systemic corticosteroids.
- An emergency room (ER) or urgent care (UC) visit (defined as evaluation and treatment for <24 hours in an ER or UC centre) due to asthma that required systemic corticosteroids.
- An inpatient hospitalisation (defined as admission to an inpatient facility and/or evaluation and treatment in a healthcare facility for ≥24 hours) due to asthma.
