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


Brief Summary

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.

Phase III


Healthy Volunteers
Minimum Age
18 Years
Maximum Age

Inclusion Criteria:

  • Age 18 years or older at the onset of Screening
  • Biopsy confirmed diagnosis of IgAN within 8 years prior to Screening
  • Proteinuria of > 1 g/day within 6 months prior to Screening or uPCR > 0.75 by spot urine at Screening
  • Mean of two proteinuria measurements > 1 g/day at baseline
  • Estimated glomerular filtration rate of ≥ 30 mL/min/1.73 m2 at Screening and baseline

Exclusion Criteria:

  • Treatment with immunosuppressants (e.g., azathioprine or cyclophosphamide), or cytotoxic drugs, for IgA within 8 weeks prior to Screening. Treatment with immunosuppressants or cytotoxic drugs for IgAN is not allowed during the Run-In Period. Treatment with immunosuppressants are allowed if such treatment is for indications other than IgAN.
  • Treatment with eculizumab within 8 weeks prior to Screening. Treatment with eculizumab is not allowed during the Run-In Period.
  • Treatment with systemic corticosteroids within 8 weeks prior to Screening. Treatment with systemic corticosteroids is not allowed during the Run-In Period.
  • Uncontrolled BP, a systolic BP of > 150 mmHg and a diastolic BP of > 100 mmHg at rest despite the combination of two or more anti-hypertensives including ACEIs, ARBs, or direct renin inhibitors at Screening and baseline
  • Female patients who are pregnant, breast feeding, or planning to become pregnant up through 12 weeks after the last dose of study drug, including possible retreatments
  • Clinical or biological evidence of Type 1 diabetes mellitus (DM), or poorly controlled DM with hemoglobin A1c > 7.5 or with evidence of diabetic nephropathy on biopsy, systemic lupus erythematosus, IgA vasculitis (Henoch-Schonlein purpura), secondary IgAN, or other renal disease during Screening and Run-In
  • History of renal transplantation
  • Have a known hypersensitivity to any constituent of the investigational product
  • Rapidly progressive glomerulonephritis
  • Significant abnormalities in clinical laboratory values
  • History of human immunodeficiency virus (HIV), evidence of immune suppression, active HCV infection (patients with positive anti-HCV antibody but a non-detected HCV RNA PCR can enroll), HBV infection (patients with positive HBsAg are excluded. For patients with isolated positive anti-HBc antibody, HBV DNA test by PCR must be non-detectable to enroll).
  • Diagnosis of a malignancy except for adequately treated and cured basal or squamous cell skin cancer, curatively treated in situ disease, or other cancer from which the patient has been disease-free for ≥ 5 years
  • Have received any other investigational drug or device or experimental procedures within 30 days of the Screening Visit (SV)
