Completed · Phase 2 · Has a placebo group

Conditions studied: Asthma

In brief

Study D9181C00001 is a Phase II, randomised, double-blind, placebo-controlled, parallel group, proof of concept study to evaluate the efficacy, safety, pharmacokinetics (PK) and immunogenicity of MEDI3506 in adult participants with uncontrolled moderate to severe asthma on standard of care (SOC). Up to approximately 80 sites globally will participate in this study. Approximately 228 participants will be randomized to 3 treatment groups in a 1:1:1 ratio to receive MEDI3506 dose 1, MEDI3506 dose 2, or placebo.
