Inclution Criteria

Key Inclusion Criteria:

Must have the ability to understand and sign a written informed consent form
Male or female of ≥18 years of age
Total urine protein excretion ≥1.0 g per 24-hour or urine protein to creatinine ratio (UPCR) ≥1.0 mg/mg based on a 24-hour urine sample during the Screening Period
Diagnosis of IgAN as demonstrated by renal biopsy conducted within 10 years
eGFR ≥ 30 mL/min/1.73 m2, as per the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation.
On a stable prescribed regimen of RAASi for at least 12 weeks that is at the maximum labeled or tolerated dose at Screening
Systolic blood pressure ≤150 mmHg and diastolic blood pressure ≤90 mmHg

Exclusion Criteria

Key Exclusion Criteria:

IgAN secondary to another condition (e.g., liver cirrhosis), or other causes of mesangial IgA deposition including IgA vasculitis (i.e., Henoch-Schonlein purpura), systemic lupus erythematosus (SLE), dermatitis herpetiformis, ankylosing spondylitis
Total urine protein excretion ≥ 5g per 24-hour or urine protein to creatinine ratio (UPCR) ≥ 5 mg/mg based on a 24-hour urine sample during the Screening Period
Evidence of rapidly progressive glomerulonephritis (loss of ≥ 50% of eGFR within 3 months of screening)
Evidence of nephrotic syndrome within 6 months of screening (serum albumin <30g/L in association with UPCR >3.5 mg/mg
Renal or other organ transplantation prior to, or expected during the study
Concomitant chronic renal disease in addition to IgAN
Uncontrolled diabetes, defined as hemoglobin-A1c (HbA1c) >7.5% at screening
