About this study
Official title: An Open-label, Multicenter Study to Assess the Effect of Zigakibart Treatment on Histologic, Circulating, and Excreted Markers of Kidney Disease and Dysfunction in Adult Patients With IgA Nephropathy.
The purpose of the study is to assess the effect of zigakibart on IgA nephropathy (IgAN) disease progression.
Read the detailed description
This is an open-label multicenter study where participants are randomized into one of two groups, where the only difference between the groups is the on-treatment biopsy time point, end of the first year of treatment (Group A) or at the end of the second year of treatment (Group B).
The total study duration for each participant may be up to 125 weeks, including the maximum screening period (8 weeks), the treatment period (104 weeks), and the safety follow up period (13 weeks).

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing zigakibart in people with Immunoglobulin A Nephropathy (IgAN), run by Novartis Pharmaceuticals at 30 sites in 11 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 21 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 30 sites in United States, Brazil, Spain, Germany, Italy and 6 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Novartis Pharmaceuticals (1-888-669-6682, novartis.email@novartis.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in mesangial IgA deposition (time frame: Baseline to Week 53 or 105). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Oct 2026.
