A Study of Lebrikizumab in Participants With Uncontrolled Asthma Who Are on Inhaled Corticosteroids and a Second Controller Medication

Hoffmann-La Roche1,081 enrolled

Overview

This randomized, multicenter, double-blind, placebo-controlled, parallel-group study will evaluate the efficacy and safety of lebrikizumab in participants with asthma whose disease remains uncontrolled despite daily treatment with inhaled corticosteroid (ICS) therapy and at least one second controller medication. Participants will be randomized in 1:1:1 ratio to receive double-blind treatment with either lebrikizumab ("high" or "low") or placebo, administered subcutaneously (SC) every 4 weeks for 52 weeks, in addition to their standard-of-care therapy. This will be followed by a 52-week double-blind active treatment extension. During double-blind active treatment extension period, all participants will receive SC injection of lebrikizumab from Week 53 to Week 104. The anticipated time on study treatment is 104 weeks. After study treatment, all participants will complete a 20-week safety follow-up.

Outcomes

Primary Outcomes

Adjusted Exacerbation Rate of Asthma During the 52-Week PCP

Asthma exacerbation is defined as new or increased asthma symptoms (i.e., wheeze, cough, dyspnea, chest tightness, and/or night-time awakening due to these symptoms) that lead to systemic corticosteroid (CS) treatment (oral, intravenous (IV), or intramuscular (IM) CS for ≥ 3 days or an emergency department visit with at least one dose of IV or IM CS) or to hospitalization. Results are reported as a 'Number' representing the model-adjusted incidence rate of asthma exacerbations per person-year. To account for early discontinuation, for each patient, the time at risk (in years) was computed as the duration of this time period (last day minus first day \[in days\] plus 1) divided by 365.25. The 'first day' was the day of randomization to the PCP. For patients entering the ATE, the 'last day' was the day prior to ATE randomization. For patients not entering the ATE, the 'last day' was at the last study visit on/prior to Study Day 379 (365 days plus a 14-day window).

Time frame: Baseline up to 52 weeks

Secondary Outcomes

Absolute Change From Baseline in Pre-Bronchodilator FEV1 at Week 52

FEV1 is the maximal amount of air, which can be forcefully exhaled in one second. Measurements were performed before use of bronchodilator. Reported is the absolute change from baseline in FEV1 to the end of the placebo-controlled period at Week 52.

Time frame: Week 52

Time to First Asthma Exacerbation During the 52-week PCP

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 hospitalisation. 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 one dose of IV or IM corticosteroids. Reported is the time to first asthma exacerbation during the 52-week placebo-controlled period.

Time frame: Baseline up to 52 weeks

Rate of Urgent Asthma-Related Health Care Utilization (HCU) During the 52-week PCP

Urgent health care utilization was defined as hospitalizations, emergency department visits, and acute care visits. Results are reported as a 'Number' representing the model-adjusted incidence rate of urgent asthma-related HCU events per person-year. To account for early discontinuation, for each patient, the time at risk (in years) was computed as the duration of this time period (last day minus first day \[in days\] plus 1) divided by 365.25. The 'first day' was the day of randomization to the PCP. For patients entering the ATE, the 'last day' was the day prior to ATE randomization. For patients not entering the ATE, the 'last day' was at the last study visit on/prior to Study Day 379 (365 days plus a 14-day window).

Time frame: Baseline up to Week 52

Absolute Change From Baseline in Standardized AQLQ Score at Week 52

Asthma-specific health-related quality of life was assessed by the overall score of the Standardized AQLQ. The AQLQ is a self-administered test with 32 questions; each with seven possible answers ranging from 1 to 7 with a higher score being more favorable. Total score is calculated as follows: sum of items 1to 32 divided by 32 for a score range of 1 to 7 with a higher score indicating a better outcome. Reported is the change in AQLQ score from baseline to the end of the placebo-controlled period at Week 52.

Time frame: Week 52

Absolute Change From Baseline In Asthma Rescue Medication Use at Week 52

Reported here is the change in the number of puffs or nebulized treatments of asthma rescue medication from baseline to the end of the PCP at Week 52.

Time frame: Week 52

Absolute Change From Baseline in ACQ-5 Score at Week 52

The ACQ-5 is test with 5 questions; each with seven possible answers ranging from 0 to 6 with a lower score being more favorable. Total score range is 0 to 30 with a lower score indicating a better outcome. Reported is the change in ACQ-5 score from baseline to the end of the PCP at Week 52.

Time frame: Baseline, Week 52
