Why the study stopped

Sponsor decision to discontinue lebrikizumab development for the treatment of asthma.

About the research

This randomized, multicenter, double-blind, placebo-controlled, parallel-group study will evaluate the efficacy of lebrikizumab compared with placebo, as measured by the ability of participants to achieve lower daily doses of OCS, among those with severe corticosteroid-dependent asthma. Prednisone/prednisolone will be the OCS therapy prescribed. Participants will be randomized to receive lebrikizumab or matching placebo for 44 weeks in a double-blind, placebo-controlled (DBPC) period. Those who complete the 44-week period may continue into a 32-week active treatment extension (ATE) period, during which all participants will receive lebrikizumab treatment. Following completion of the ATE period, participants who have both tolerated and derived benefit from treatment with lebrikizumab may continue their lebrikizumab treatment into a long-term extension (LTE) period. Participants will transition to 24 weeks of safety follow-up upon discontinuation of study drug.

Who may be able to participate?

Treatment, groups and participation

The registry may describe treatments and study duration without a complete visit calendar. Ask the study team for the exact schedule, procedures, risks, costs and alternatives. Keep your usual care plan unless your treating clinician tells you otherwise.

Assignment: Random assignment
Masking: Double masked

Lebrikizumab High Dose

Participants will receive lebrikizumab at high dose level as subcutaneous (SC) injection every 4 weeks during the 44-week DBPC period, followed by a 32-week ATE period, and during the LTE period.

Drug: Lebrikizumab

Lebrikizumab Low Dose

Participants will receive lebrikizumab at low dose level as SC injection every 4 weeks during the 44-week DBPC period, followed by a 32-week ATE period, and during the LTE period.

Drug: Lebrikizumab

Placebo

Participants will receive placebo matching to lebrikizumab SC injection every 4 weeks during the 44-week DBPC period. Participants will then be randomized to receive either high- or low-dose lebrikizumab every 4 weeks during the 32-week ATE period and will continue same treatment in the LTE period.

Drug: Lebrikizumab · Drug: Placebo

Lebrikizumab DRUG

Lebrikizumab will be administered as SC injections every 4 weeks at dose and schedule described in arm description.

Placebo DRUG

Placebo matching to lebrikizumab will be administered as SC injections every 4 weeks as per schedule described in arm description.

What researchers are measuring

Outcome measures describe what is being studied. They are not proof that a treatment works.

Primary measures

Percent Change From Baseline in Daily Oral Corticosteroid (OCS) Dose at Week 44

Time frame: Baseline (including 28 days prior to Day 1), Week 44 (including 28 days prior to Week 44)

OCS used in study: prednisone/prednisolone. Participants entered their total daily use of OCS into an electronic diary (eDiary) on a daily basis. The OCS intake since the previous study visit and the prescribed OCS dose for the next 28 days was captured by physician on a dedicated page in the electronic Case Report Form (eCRF). Baseline OCS dose was calculated using the eDiary as average daily dose over 28 days prior to randomization. Post-baseline OCS dose was obtained from the eCRF and calculated as average daily dose over the 28 days preceding the timepoint. Percent change = (post-baseline value - baseline value)/baseline value \* 100.

Secondary measures

Absolute Change From Baseline in Daily OCS Dose at Week 44

Time frame: Baseline (including 28 days prior to Day 1), Week 44 (including 28 days prior to Week 44)

OCS used in study: prednisone/prednisolone. Participants entered their total daily use of OCS into an eDiary on a daily basis. The OCS intake since the previous study visit and the prescribed OCS dose for the next 28 days was captured by physician on a dedicated page in the eCRF. Baseline OCS dose was calculated using the eDiary as average daily dose over 28 days prior to randomization. Post baseline OCS dose was obtained from the eCRF and calculated as average daily dose over the 28 days preceding the timepoint.

Percent Change From Week 12 in Daily OCS Dose at Week 44

Time frame: Week 12 (including 28 days prior to Week 12), Week 44 (including 28 days prior to Week 44)

OCS used in study: prednisone/prednisolone. Participants entered their total daily use of OCS into an eDiary on a daily basis. The OCS intake since the previous study visit and the prescribed OCS dose for the next 28 days was captured by physician on a dedicated page in the eCRF. OCS dose at a timepoint was obtained from the eCRF and calculated as average daily dose over the 28 days preceding the timepoint. Percent change = (value at Week 44 - value at Week 12)/value at Week 12 \* 100. Reported values are adjusted mean values obtained from MMRM analysis.

Percentage of Participants Who Achieved at Least a 50 Percent (%) Reduction in Their Daily OCS Dose at Week 44 Relative to Baseline

Time frame: Baseline (including 28 days prior to Day 1), Week 44 (including 28 days prior to Week 44)

Percentage of Participants Who Either Discontinued OCS Therapy or Achieved an Adrenal Maintenance Dose at Week 44

Time frame: Week 44

Percentage of participants who either discontinued OCS therapy or have achieved an adrenal maintenance dose is reported. Identification of participants achieving adrenal maintenance dose was based on physician assessment recorded in eCRF in the presence of cortisol = 100 nanomoles per liter (nmol/L). The 95% CI for the percentage was based on normal approximation for binomial proportion.

Rate of Asthma Exacerbations During the 44-Week Double-Blind Placebo Controlled (DBPC) Period

Time frame: Baseline up to Week 44

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.
