Eligibility criteria

Key Inclusion Criteria:

  • Diagnosis of IgAN as confirmed by renal 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.
  • ≥ 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, 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 or other 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
Terms in these criteria, in plain language(5)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Biopsy and archival tissue

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.

Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

GFR and eGFR (kidney filtering)

GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².

Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Jun 2026; primary completion for Sep 2028, 27 months later.

Of 26 phase 3 interventional studies under Glomerulonephritis, IGA, half reached primary completion within 55 months of starting (the median), counting those still running; a quarter within 39 and three quarters within 70. This study's planned 27 months is below that.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 11, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
