A Phase II, Randomized, Double-Blind, Placebo-Controlled Bronchoscopy Study to Evaluate the Effects of Lebrikizumab on Airway Eosinophilic Inflammation in Patients With Uncontrolled Asthma on Inhaled Corticosteroids and a Second Controller Medication
Description
Brief Summary
This Phase II, randomized, double-blind, placebo-controlled, multicenter study will evaluate
the effects of lebrikizumab on airway eosinophilic inflammation in participants with
uncontrolled asthma who are using inhaled corticosteroid (ICS) treatment and a second
controller medication. Enrolled participants will undergo a 3-week screening period during
which assessments, including a bronchoscopy procedure, will be made. Participants will
subsequently be randomized to receive lebrikizumab or placebo by subcutaneous (SC) injection
on Day 1, Day 8, Week 4, and Week 8. Participants will continue their standard of care
therapy throughout the study. End of treatment assessments will be taken at Week 12. Total
study period, including screening and follow-up, is expected to last 23 weeks.
Phase
Phase 2 - takes the treatment one step further, assessing the activity of a particular therapy in a disease, often building upon leads from the Phase I trial. While patients are generally required to be previously untreated, participation in a Phase II trial doesn't usually preclude the patient from getting the standard treatment after they've received the investigational agent. At best they are allowed to get a new drug they wouldn't be able to get otherwise that may turn out to be better for their disease.Inclusion and Exclusion Criteria
- Asthma diagnosis for greater than or equal to (>/=) 12 months prior to Visit 1

- 80% predicted at both Visits 2 and 3
- On ICS therapy at a total daily dose of 500-2000 mcg of fluticasone propionate dry powder inhaler (DPI) or equivalent for >/= 6 months prior to Visit 1, with no changes within 4 weeks prior to Visit 1, and no anticipated changes throughout the study
- On an eligible second controller medication (long-acting Beta-agonist [LABA), leukotriene receptor antagonist [LTRA], long-acting muscarinic antagonists [LAMAs] or theophylline) for 6 months prior to Visit 1, with no changes within 4 weeks prior to Visit 1, and no anticipated changes throughout the study
- Uncontrolled asthma at Visit 1 and/or 2 and at Visit 3

- Demonstrated adherence with controller medication during the screening period
- Maintenance oral corticosteroid therapy, defined as daily alternate-day oral corticosteroid maintenance therapy within 3 months prior to Visit 1
- Treatment with systemic corticosteroids within 4 weeks prior to Visit 1 or during the screening period for any reason, including an acute exacerbation event
