Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Key Inclusion Criteria:

  • Diagnosis of IgAN as confirmed by renal biopsy conducted within 10 years prior to Screening.

    • If a participant has a history of diabetes, the biopsy must have been conducted within 2 years prior to Screening with no evidence of diabetic nephropathy.
    • In all cases, if a historical biopsy report is not available, a biopsy may be performed prior to Screening.
  • UPCR ≥ 0.75 g/g or UPE ≥ 1.0 g/d determined via 24 hour collection.
  • eGFR ≥ 30 mL/min/1.73m2 (CKD-EPI equation).
  • Participants must have been on supportive care including a stable dose regimen of ACEi or ARB (at the locally approved maximal daily dose or the maximally tolerated dose per Investigators' judgment) for at least 90 days prior to Screening. Subjects who are not able to tolerate ACEi or ARB therapy may be eligible for participation in the trial if their overall management including blood pressure control is as per local applicable guidelines. This must be discussed with the medical monitor and documented by the Investigator.
  • Patients may be on a dual endothelin angiotensin receptor antagonist (DEARA) or endothelin receptor antagonist (ERA) but must be on a stable dose for at least 90 days prior to Screening and they must remain on a stable dose throughout the course of the study. Participants may be on a sodium-glucose cotransporter 2 (SGLT2) inhibitor, mineralocorticoid receptor antagonist (including Finerenone), but must be on a stable dose for 90 days prior to Screening and must remain on a stable dose throughout the course of the study.

Key Exclusion Criteria:

  • Any secondary IgAN as defined by the Investigator; secondary IgAN can be associated with cirrhosis, celiac disease, HIV infection, herpetiformis, seronegative arthritis, small-cell carcinoma, lymphoma, disseminated tuberculosis, bronchiolitis obliterans, inflammatory bowel disease, familial Mediterranean fever, etc. NOTE: IgA Vasculitis excluded if patient has had any IgA Vasculitis related extrarenal signs or symptoms, or requirement for steroid or other immunosuppressive therapy in the past year.
  • Any cause of chronic kidney disease that is not diagnosed as IgAN or may be due to non-IgAN cause, such as diabetic nephropathy. If presence of other kidney disease or concurrent glomerulopathies felt to be non-dominant, consideration for inclusion must be discussed with and approved by the Sponsor Medical Monitor/Sponsor Designee.
  • Presence of rapidly progressive glomerulonephritis as defined by 50% decline in eGFR within 3 months prior to Screening.
  • Evidence of nephrotic syndrome, defined as 24-hour protein > 3.5g with concurrent hypoalbuminemia (Albumin < 3.0 g/dl), within 6 months of Screening
  • End-stage renal disease requiring dialysis or transplantation
