About

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.

Lebrikizumab Low

Experimental group

Description:

Participants with uncontrolled asthma on ICS therapy (total daily dose of 500-2000 mcg of fluticasone propionate DPI or equivalent) and a second controller medication, will receive SC injection of lebrikizumab (low dose) Q4W for 52 weeks during placebo-controlled period and up to 76 weeks or 104 weeks for participants who will be willing to take part in optional active-treatment extension period.
