Etokimab in Adults With Chronic Rhinosinusitis With Nasal Polyps (CRSwNP)

Phase 2
Completed
Conditions
Chronic Rhinosinusitis
Interventions
Biological: Etokimab
Biological: Placebo
Drug: Mometasone Furoate Nasal Spray
Registration Number
NCT03614923
Lead Sponsor
AnaptysBio, Inc.
Brief Summary

A study to evaluate the safety and efficacy of multiple doses of etokimab in adults with chronic rhinosinusitis with nasal polyps.

Detailed Description

This study is a randomized, placebo controlled, double-blind, multi-dose study to assess the efficacy of two different dose regimens of etokimab compared to placebo in adults with moderate-to-severe chronic sinusitis with nasal polyposis (CRSwNP).

During the screening period, all subjects will undergo evaluation for eligibility. A centralized reader will be used to confirm the diagnosis of CRSwNP as assessed by nasal endoscopy, computed tomography (CT) scan of sinuses, and symptom scoring to reduce the risk of interpretation variation.

Participants will also be provided mometasone furoate nasal spray (MFNS) for use during the trial and are required to undergo a minimum run-in period of 20 days prior to Day 1 with approximately 80% compliance.

Participants will be randomly assigned on Day 1 to one of the three treatment arms in a 1:1:1 ratio.

Primary Outcome Measures
NameTimeMethod
Change From Baseline in Nasal Polyp Score (NPS) to Week 16Baseline and Week 16

Nasal polyps were evaluated by nasal endoscopy using centralized imaging data assessments scored by an independent reviewer.

Each nostril was scored on a scale from 0 to 4, where a score of 0 means no polyps, and a score of 4 means the presence of polyps causing complete obstruction of the inferior nasal cavity.

The bilateral NPS score is the sum of the right and left nostril scores, and hence the total NPS value is between 0 and 8 (worst). A negative change from Baseline indicates improvement.

Change From Baseline in Sino-Nasal Outcome Test-22 (SNOT-22) Score at Week 16Baseline and Week 16

SNOT-22 is a 22-item outcome measure on a 5-category scale that assesses symptoms and social/emotional consequences of rhinosinusitis. Each item is scored from 0 (No problem at all) to 5 (Problem as bad as it can be), and the total score ranges from 0 to 110. Higher SNOT-22 scores are indicative of greater impact of rhinosinusitis on quality of life. A negative change from Baseline indicates improvement.
