Study of the Safety and Efficacy of OMS721 in Patients With Immunoglobulin A (IgA) Nephropathy

Brief description of study

The purpose of this study is to evaluate the safety and efficacy of OMS721 in patients with IgA nephropathy. The study will assess proteinuria by 24-hour urine protein excretion (UPE) in g/day at 36 weeks from beginning of treatment.

Detailed Study Description

This is a Phase 3, double-blind, randomized, placebo-controlled, study in patients aged 18 years and above with a biopsy-confirmed diagnosis of IgAN and with 24-hour UPE that is > 1 g/day within 6 months prior to Screening or uPCR > 0.75 by spot urine at Screening. During the study, all patients will continue optimized renin-angiotensin system (RAS) blockade. The study consists of five periods: Screening, Run-In, Initial Treatment (Weeks 1-12), Response Evaluation (Weeks 13-36), and Follow-Up (Weeks 37-144). Patients are assessed for re-treatment based on their response to 24-hour UPE. Additional treatment may be given to patients whose 24-hour UPE is > 1 g/day following the Initial Treatment Period and who relapse during the Response Evaluation and Follow-Up periods. Patients may be qualified for Open-Label Treatment with OMS721 after Week 72.

Approximately 450 patients are to enrolled in two groups of 225 patients per arm.
