Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Approximately 250 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 (Open Label Extension), during which all patients will receive 8 doses of benralizumab 30 mg. Patients in Benra arm during DB period will receive one dummy dose for the second dose during OLE (Open Label Extension). The last study visit will occur at 8 weeks after the last dose of IP (Week 112/FU). Patients who do not enter OLE (Open Label Extension), will have their last study visit at Week 56 (EoDB) for follow-up and without administration of IP.

Benralizumab

Benralizumab administered subcutaneously

Group Type EXPERIMENTAL

Benralizumab 30 mg

Intervention Type BIOLOGICAL

Benralizumab is 30 mg/ml solution for injection in accessorized pre-filled syringe, 1 ml fill volume.

Benralizumab 30 mg subcutaneously will be injected 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).

For OLE, Benralizumab 30 mg subcutaneously will be injected every 4 weeks for the first 3 doses and every 8 weeks for the rest 5 doses. For the patients on Benralizumab treatment during double blind period, placebo will be dosed at the second dose during OLE.

Placebo

4. Bilateral sinonasal polyposis with a nasal polyp score (NPS) of 5 at enrolment and randomization (unilateral score of at least 2 for each nostril)
5. Ongoing symptoms for at least 12 weeks prior to enrolment
6. Patient-reported moderate to severe nasal blockage score (NBS) ≥2 at enrolment
7. Bi-weekly mean NBS ≥ 1.5 at randomization
