Mild Atopic Asthma
Conditions
Brief summary
This randomized, observer-blinded, placebo-controlled, single and multiple ascending-dose study will be conducted in two parts to evaluate the safety, pharmacokinetics, and immunogenicity of BITS7201A. Part A will be an ascending, single-dose, sequential-group study where participants will be randomly assigned to active drug or placebo. Part B will be an ascending, multiple-dose, sequential-group study where participants will be randomized to active drug or placebo. Total length of the study is anticipated to be approximately 12 months.
Interventions
BITS72014A will be administered on Day 1 in Part A and on Days 1, 28, and 57 in Part B.
Placebo matched to BITS72014A will be administered on Day 1 in Part A and on Days 1, 28, and 57 in Part B.
