  • If local regulations are more stringent than the contraception methods listed above, local regulations apply and will be described in the ICF.
  • Women are considered post-menopausal if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g., age appropriate, history of vasomotor symptoms). Women are considered not of childbearing potential if they are post-menopausal or have had surgical bilateral oophorectomy (with or without hysterectomy), total hysterectomy or tubal ligation at least six weeks ago. In the case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment is she considered not of childbearing potential.
  • If local regulations deviate from the contraception methods listed above to prevent pregnancy, local regulations apply and will be described in the ICF.

About this study

Official title: A Multicenter, Single Arm, Open Label Biopsy Study to Evaluate Structural and Functional Changes in Kidneys of Adult Patients With IgA Nephropathy Receiving Iptacopan on Top of Supportive Care

A study to investigate the impact of iptacopan treatment on the underlying immunopathology in patients with IgAN by assessing changes in key clinical and molecular markers from baseline to 9 months. The study aims to provide insights into the treatment's systemic and kidney-specific aspects by quantifying the change in mesangial C3c containing fragments deposition, as an indicator of complement activation, and evaluating a variety of biomarkers related to kidney function, damage, and disease progression, including but not limited to Oxford MEST-C score.

Read the detailed description

The study comprises of a screening period followed by a baseline visit, at which a baseline kidney biopsy will be performed. Eligible participants included in the study will receive iptacopan 200 mg b.i.d for a 9-month treatment period. Dose adjustment of iptacopan is not allowed during the treatment period. At Month 9, upon completion of the treatment period, a follow up biopsy is performed for all participants at the time of end of study (EOS).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Proportion of participants achieving a reduction of minimum one order of magnitude in complement C3c mesangial deposition.

    Mesangial C3c deposition is assessed by intensity of immunofluorescence (IF) staining using the following grading system: 0 (absent) 1 (+) 2 (++) 3 (+++)

    Measured: BSL, Month 9

Secondary outcomes (2)
  1. Change from baseline at 9 months in CD68 cells

    To describe the histopathological changes in additional biomarkers after treatment with iptacopan

    Measured: BSL, Month 9

  2. Change from baseline at 9 months in staining of Immunoglobulins (IgA and IgG)

    To describe the histopathological changes in additional biomarkers after treatment with iptacopan

    Measured: BSL, Month 9

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Iptacopan in people with Glomerulonephritis, IGA and Immunoglobulin A Nephropathy, run by Novartis Pharmaceuticals at 19 sites in 5 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 7 inclusion and 34 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 29 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 19 sites in United States, Israel, Argentina, Malaysia, Saudi Arabia. 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?

Proportion of participants achieving a reduction of minimum one order of magnitude in complement C3c mesangial deposition. (time frame: BSL, Month 9). 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 29 Jul 2026.
