A Study of JNJ-38518168 in Symptomatic Adult Participants With Uncontrolled, Persistent Asthma

Janssen Research & Development, LLC166 enrolled

Overview

The purpose of this study is to evaluate the efficacy, safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of JNJ-38518168 compared with placebo in participants with persistent asthma that is inadequately controlled despite current treatment.

This study will be randomized (treatment group assigned by chance, like flipping a coin), double-blind (study investigators and participants will not know what treatment is being administered), and placebo-controlled (a placebo is identical to the study agent, but contains no active ingredients). A total of 160 participants will receive either placebo or JNJ-38518168 once daily. The study duration will be approximately 32 weeks and will include a screening phase of approximately 4 weeks, a 24-week placebo-controlled treatment phase, and a 4-week follow-up phase. Participant safety will be monitored throughout the entire study period..
