Clinical Trial Summary

This is a randomized, double-blind, placebo-controlled, parallel-group, international, multicenter, Phase 3 study to evaluate the efficacy and safety of repeat dosing of benralizumab 30 mg administered subcutaneously (SC) versus placebo in patients with severe nasal polyposis.

Description:

Approximately 275 patients will be randomized to receive benralizumab 30 mg SC or matching placebo. After enrolment, eligible patients will enter a 6-week screening/run in period. Patients who meet eligibility criteria will be randomised 1:1 at Week 0 (Day 0) to receive either placebo or benralizumab 30 mg SC every 4 weeks for the first 3 doses (Weeks 0, 4 and 8) and every 8 weeks thereafter (Weeks 16, 24, 32, 40 and 48). An end of treatment visit will be conducted at Week 56.All patients who complete the 56-week DB treatment period on investigational product (IP) may be eligible to continue into around one year OLE, during which all patients will receive 8 doses of benralizumab 30 mg. Patients in Benra arm during DB period will receive one dummy dose. The last study visit will occur at 8 weeks after the last dose of IP (Week 112/FU). Patients who do not enter OLE, will have their last study visit at Week 56 (EoDB) for follow-up and without administration of IP.
