Asthma
Conditions
Brief summary
This randomized, multicenter, double-blind, placebo-controlled, parallel-group study will evaluate the efficacy, safety, and tolerability of lebrikizumab in adolescent participants with asthma whose disease remains uncontrolled despite daily treatment with inhaled corticosteroids (ICS) therapy and at least one second controller medication. Participants will be randomized in a 1:1:1 ratio to receive double-blind treatment with either lebrikizumab ('High' or 'Low') or placebo, administered as subcutaneous (SC) every 4 weeks (Q4W) for 52 weeks, in addition to their standard-of-care therapy. This will be followed by an optional 52-week double-blind active-treatment extension. The anticipated time on study treatment is up to 104 weeks. Participants who complete the study to Week 104, discontinue prematurely or decide not to take part in the optional active-treatment extension will transition to the 20-week safety follow-up period.
Interventions
Lebrikizumab will be administered as SC injection at high or low dose Q4W.
Lebrikizumab matching placebo will be administered as SC injection Q4W.
Participants will continue to receive ICS therapy (total daily dose of 500-2000 mcg fluticasone propionate DPI or equivalent) along with at least one second controller medications (e.g. long-acting beta agonists \[LABAs\], leukotriene receptor antagonists (LTRAs), long-acting muscarinic antagonists (LAMAs), or theophylline) as standard of care.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Rate of Asthma Exacerbations During 52-Week Placebo Controlled Period | Baseline up to Week 52 | An asthma exacerbation is defined as new or increased asthma symptoms (including wheeze, cough, dyspnea, chest tightness, and/or night-time awakening due to these symptoms) that lead to treatment with systemic corticosteroids or to hospitalization. Treatment with systemic corticosteroids is defined as treatment with oral, intravenous (IV), or intramuscular (IM) corticosteroids for at least 3 days or an emergency department visit with at least 1 dose of IV or IM corticosteroids. Rate of asthma exacerbation = total number of exacerbation events divided by total follow-up time in patient years. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change From Baseline in Fractional Exhaled Nitric Oxide (FeNO) at Week 52 | Week 52 | Measurement of FeNO (in parts per billion \[ppb\]) was performed using a hand-held portable NIOX MINO® device, in accordance with guidelines published by the American Thoracic Society (ATS) and described in the pulmonary function testing manual. |
| Change From Baseline in Standardized Asthma Quality of Life Questionnaire for 12 Years and Older (AQLQ+12) Overall Score at Week 52 | Week 52 | The Standardized AQLQ+12 was used to assess the participants' asthma-specific health-related quality of life. The AQLQ+12 had a recall specification of 2 weeks. The AQLQ+12 was a 32-item questionnaire with 4 domains: activity limitations, symptoms, emotional function, and environmental stimuli. Each of the 32 questions were scored on a scale 1-7. The overall AQLQ+12 score is the mean of the responses to each of the 32 questions, and ranges from 1 to 7. A score 7 indicated no impairments due to asthma, and a score of 1 indicated severe impairment. |
| Percent Change From Baseline in Pre-Bronchodilator Forced Expiratory Volume in 1 Second (FEV1) at Week 52 | Week 52 | FEV1 is the maximal volume of air exhaled in the first second of a forced expiration from a position of full inspiration. The baseline FEV1 was obtained from the last spirometric analysis performed before the first study treatment administration. The percentage change in pre-bronchodilator FEV1 was defined as the change in FEV1 (in liters) from baseline divided by the FEV1 (in liters) at baseline multiplied by 100. |
| Absolute Change From Baseline in Pre-Bronchodilator FEV1 at Week 52 | Week 52 | FEV1 is the maximal volume of air exhaled in the first second of a forced expiration from a position of full inspiration. The baseline FEV1 was obtained from the last spirometric analysis performed before the first study treatment administration. Reported is the absolute change from baseline in FEV1 to the end of the placebo-controlled period at Week 52. |
| Change From Baseline in Asthma Rescue Medication Use at Week 52 | Week 52 | Participants were allowed to use short-acting bronchodilators as asthma rescue medication. Baseline asthma rescue medication use was defined as the average number of puffs per day over the 7 days prior to and on the day of randomization. Participants must have recorded their asthma rescue medication use for at least 4 days to have a baseline score calculated. The post-baseline asthma medication use for any timepoint was defined as the average number of puffs per day over the last 28 days on or prior to the timepoint. Participants must have recorded their asthma rescue medication use for at least 14 days during a 28-day interval to have a score calculated for the respective timepoint. For nebulizer use, one treatment (inhalation) was considered equivalent to 4 puffs. |
| Rate of Urgent Asthma-Related Health Care Utilization (HCU) Events | Baseline up to Week 52 | Urgent asthma-related HCU events included hospitalizations, emergency department visits, and acute care visits. Rate of urgent asthma-related HCU events = total number of urgent asthma-related HCU events divided by total follow-up time in patient years. |
| Injection Acceptability Questionnaire (IAQ) Score | Baseline, Weeks 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48 | The acceptability of the injections of study drug was addressed by measuring the level of pain that participants experienced. Participants assessed pain associated with study drug administration using the IAQ within 10 minutes of study drug administration. The IAQ score ranged from 0 to 10; where 0 = no pain and 10 = worst pain imaginable. |
| Time to First Asthma Exacerbation | Baseline up to Week 52 | An asthma exacerbation was defined as new or increased asthma symptoms (including wheeze, cough, dyspnea, chest tightness, and/or night-time awakening due to these symptoms) that lead to treatment with systemic corticosteroids or to hospitalization. Treatment with systemic corticosteroids was defined as treatment with oral, IV, or IM corticosteroids for at least 3 days or an emergency department visit with at least 1 dose of IV or IM corticosteroids. Median time to first protocol-defined asthma exacerbation was estimated using Kaplan-Meier analysis. 95% Confidence interval (CI) for median was computed using the method of Brookmeyer and Crowley. |
| Minimum Observed Serum Concentration (Ctrough) for Lebrikizumab | Predose (Hour 0) at Weeks 4, 12, 24, 36, and 52 | Participants who received at least one dose of lebrikizumab and had at least one post-baseline evaluable sample were included in the analysis. Results of post-dose samples which were less than reportable were set to 0.045 micrograms per milliliter (mcg/mL) that is half of minimum quantifiable concentration value (0.09 mcg/mL). |
