Evaluation of Dupilumab in Patients With Persistent Asthma (Liberty Asthma Quest)

Summary

Primary Objective: To evaluate the efficacy of dupilumab (SAR231893 / REGN668) in participants with persistent asthma. Secondary Objectives: * To evaluate the safety and tolerability of dupilumab. * To evaluate the effect of dupilumab on improving participant-reported outcomes including health-related quality of life. * To evaluate dupilumab systemic exposure and incidence of anti-drug antibodies.

Outcome

Met primary endpoint

paper for a 47.7% lower rate with dupilumab than with placebo (P<0.001); similar results were seen with the dupilumab dose of 300 mg every 2 weeks. PMID 29782217 ↗

paper At week 12, the FEV1 had increased by 0.32 liters in patients assigned to the lower dose of dupilumab (difference vs. matched placebo, 0.14 liters; P<0.001) PMID 29782217 ↗
