Asthma
Conditions
Brief summary
This Phase III, randomized, double-blind, placebo-controlled, multicenter study will assess the efficacy and safety of lebrikizumab in adult patients with mild to moderate asthma treated with short-acting beta-agonist (SABA) therapy alone. Patients will be randomized in a 1:1:1 ratio to receive either blinded lebrikizumab or placebo treatment by subcutaneous (SC) injection (every 4 weeks for a total of 3 doses) or open-label treatment with Singulair (Montelukast; 10 mg daily). Time on study treatment will last 12 weeks.
Interventions
Lebrikizumab 125 mg subcutaneous (SC) injection given on Days 1, 29, and 57
10 mg tablet given orally once daily for 12 weeks, according to the approved label.
Lebrikizumab-matched placebo SC injection given on Days 1, 29, and 57

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change From Baseline in Pre-bronchodilator Forced Expiratory Volume in 1 Second (FEV1) at Week 12 | Baseline through Week 12 | FEV1 is the amount of air which can be forcibly exhaled from the lungs in the first second of a forced exhalation. The active comparator treatment arm of open-label montelukast was included in the study design so that the sensitivity of the study could be evaluated with respect to the primary outcome measure, FEV1. Two mixed-effect models of repeated measures (MMRM) were used to estimate the absolute change from baseline values: one for the lebrikizumab vs. placebo primary comparison and the second for the montelukast vs. placebo sensitivity comparison. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Lebrikizumab vs. Placebo: Change From Baseline in Asthma Reliever Medication Use at Week 12 | Baseline through Week 12 | Participants could only receive SABA therapy for asthma treatment as asthma reliever medication (\<10 puffs daily). SABA use was recorded in the eDiary. A mixed-effect model of repeated measures (MMRM) was used to estimate the absolute change from baseline values for the comparison between the double-blind lebrikizumab and placebo study arms. |
| Lebrikizumab vs. Placebo: Change From Baseline in the Standardized Asthma Quality of Life Questionnaire (AQLQ[S]) Overall Score at Week 12 | Baseline through Week 12 | The AQLQ\[S\] was used to assess the participant's asthma-specific health-related quality of life. The 32-item questionnaire contains four domains: activity limitations, symptoms, emotional function, and environmental stimuli. The AQLQ\[S\] has a recall specification of 2 weeks. Participants were asked to think about how they had been during the previous 2 weeks and to respond to each of the 32 questions on a 7-point scale (7 = not impaired at all; 1 = severely impaired). An increase in the AQLQ score indicates a better quality of life. The overall AQLQ score is the mean of all 32 responses and the individual domain scores are the means of the items in those domains. A mixed-effect model of repeated measures (MMRM) was used to estimate the change from baseline values. |
| Change From Baseline in Fractional Exhaled Nitric Oxide (FeNO) Levels at Week 12 | Baseline, Week 12 | — |
| Montelukast vs. Placebo: Change Fom Baseline in Morning Pre-bronchodilator Peak Expiratory Flow (PEF) at Week 12 | Baseline through Week 12 | PEF is defined as the maximum airflow during a forced expiration beginning with the lungs fully inflated. The active comparator treatment arm of open-label montelukast was included in the study design so that the sensitivity of the study could be evaluated with respect to this secondary outcome measure of PEF. A mixed-effect model of repeated measures (MMRM) was used to estimate the absolute change from baseline values for the sensitivity comparison between montelukast (open-label, active comparator) and placebo study arms. |
| Lebrikizumab vs. Placebo: Change From Baseline in Morning Pre-bronchodilator PEF at Week 12 | Baseline through Week 12 | Peak expiratory flow (PEF) is defined as the maximum airflow during a forced expiration beginning with the lungs fully inflated. A mixed-effect model of repeated measures (MMRM) was used to estimate the absolute change from baseline values for the comparison between the double-blind lebrikizumab and placebo study arms. |
| Lebrikizumab vs. Placebo: Number of Participants With Treatment Failure | Baseline up to Week 12 | Treatment failure was defined as a worsening of asthma symptoms (per investigator's assessment of participant report) in association with either relative decline in pre-bronchodilator FEV1 \>=20%; or \>=20% decline in morning pre-bronchodilator PEF on 2 consecutive days compared with baseline; or use of \>=10 puffs of albuterol metered dose inhaler (MDI); or \>=2 additional administrations (or any new use) of nebulized short-acting β-agonist (SABA) therapy within any calendar day; or need for any inhaled, oral, or parenteral corticosteroid or for a controller medication. The hazard ratio from the Cox Proportional Hazards model compared the risk of treatment failure for the lebrikizumab-treated and placebo participants. |
| Lebrikizumab vs. Placebo: Time to Treatment Failure | Basleine up to Week 12 | Treatment failure was defined as a worsening of asthma symptoms (per investigator's assessment of participant report) in association with either relative decline in pre-bronchodilator FEV1 \>=20%; or \>=20% decline in morning pre-bronchodilator PEF on 2 consecutive days compared with baseline; or use of \>=10 puffs of albuterol metered dose inhaler (MDI); or \>=2 additional administrations (or any new use) of nebulized short-acting β-agonist (SABA) therapy within any calendar day; or need for any inhaled, oral, or parenteral corticosteroid or for a controller medication. Time to treatment failure was estimated using Kaplan-Meier method. |

| Change From Baseline in Serum Periostin at Week 12 | Baseline, Week 12 | — |
| Change From Baseline in Total Immunoglobulin E (IgE) Levels at Week 12 | Baseline, Week 12 | — |

| Change From Baseline in CCL-17 Levels at Week 12 | Baseline, Week 12 | — |
| Maximum Serum Lebrikizumab Concentration (Cmax) After the First Dose | Predose on Day 0 and post-Day 1 dose on Day 7 | According to the protocol and statistical analysis plan, a single PK sample was collected per participant after the first dose at the expected time of the maximum serum lebrikizumab concentration. |
| Time to Reach Maximum Lebrikizumab Concentration After the First Dose (Tmax) | Post-Day 1 dose on Day 7 | According to the protocol and statistical analysis plan, the Tmax, Week1 (first dose) value was estimated on the basis of a single pharmacokinetic (PK) timepoint per participant after the first dose, which was taken at the expected time of the maximum serum lebrikizumab concentration. |
| Elimination Half-Life (t1/2) of Lebrikizumab | Predose on Days 0, 28, and 56, and on Days 7, 84, 112, and 140 | According to the protocol and statistical analysis plan, the t1/2 was estimated based on the seven total PK samples collected per participant. |
| Predose Serum Lebrikizumab Concentration (Cmin) at Week 4 | Predose on Day 28 (Week 4) | — |
| Serum Lebrikizumab Concentration at Week 12 | On Day 84 (Week 12) | — |

Pre-assignment details
Out of 313 enrolled participants, 3 were randomized but not treated during a 12-week treatment period where participants received blinded lebrikizumab/placebo or an open-label active comparator (montelukast sodium). The montelukast arm (active comparator) was included in the study design so that the sensitivity of the study could be evaluated with respect to the primary outcome measure of FEV1, and the secondary outcome measure of PEF.
