Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 2 to 18 years
  • All sexes
  • No healthy volunteers
  • Child, Adult

Who may be able to join

  • Male and female participants 2 to < 18 years of age as of Day 1.
  • eGFR ≥ 30 mL/min/1.73m2 where eGFR is calculated using the modified Schwartz formula at Screening and confirmed during the Run-in Period.
  • Kidney biopsy-proven primary IgAN*, with biopsy performed within 3 years of Screening with < 50% tubulointerstitial fibrosis and < 25% crescents. In case a kidney biopsy within 3 years from Screening is not available, a kidney biopsy may be performed if it is part of the planned diagnostic approach and clinical management of the participant.
  • Note: Primary IgAN is defined as any IgAN that is proven by biopsy showing IgA deposits prevalent over the other classes of immunoglobulins and deemed not to be associated with causes of secondary IgAN as per clinical judgment of the Investigator.
  • The minimum body weight for participants in Cohort 1 is 35 kg at Screening and confirmed at Baseline (Day 1).
  • Proteinuria due to primary diagnosis of IgAN as assessed by UPCR ≥ 1 g/g (113 mg/mmoL) sampled from FMV at Screening on Day -90 and Day -60 as well as during the Run-in Period despite treatment with maximum tolerated dose of ACE inhibitor/ARB for at least 120 days prior to Day 1. Note: UPCR will be assessed based on one FMV sample at Day -90 and based on the geometric mean of 2 FMV samples for the Day -60 visit and during the Run-in Period.

  • Vaccination against Neisseria meningitidis and Streptococcus pneumoniae infection is required prior to the start of study treatment. If the participant has not been previously vaccinated, or if a booster is required, vaccine should be given according to local guidelines at least 2 weeks prior to first study drug administration. If study treatment has to start earlier than 2 weeks post vaccination, prophylactic antibiotic treatment should be initiated.
  • Vaccination against Haemophilus influenzae is recommended, according to local guidelines, at least 2 weeks before iptacopan.
  • All participants must have been on supportive care including stable dose regimen of ACE inhibitor or ARB at either the locally approved maximal daily dose per body weight, or the maximally tolerated dose (per Investigator's judgment for pediatric use), for at least 120 days before first study drug administration. In addition, if participants are taking diuretics, other antihypertensive medication, or other background medication for IgAN (such as SGLT2 inhibitors), the doses should also be stabilized for at least 120 days prior to the first dosing of study treatment.

Who cannot join

About this study

Official title: A Single-arm, Multicenter, Phase III Study to Assess Efficacy, Pharmacokinetics, Safety and Tolerability of Iptacopan in Pediatric Patients of 2 to <18 Years of Age With Primary Immunoglobulin A Nephropathy (IgAN)

The study is an open-label, single arm, multicenter, Phase III study to determine proteinuria reduction, pharmacokinetics (PK), safety and tolerability (including CV surveillance) of iptacopan in primary immunoglobulin A nephropathy (IgAN) pediatric patients aged 2 to <18 years.

Read the detailed description

The study will enroll approximately 34 pediatric patients with a diagnosis of primary IgAN by kidney biopsy performed within 3 years of Screening with < 50% tubulointerstitial fibrosis and <25% crescents and not previously treated with immunosuppressive or other immunomodulatory agents within 90 days (or 180 days for rituximab) prior to first study drug administration.

The study comprises the following periods:

  • Screening Period (up to 11 weeks)
  • Run-in Period (2 weeks): This period will be approximately 14 days prior to the Enrollment Visit (Day 1) to obtain Baseline assessments, including two UPCR FMV measurements (required prior to Day 1).
  • Treatment Period ( 52 weeks): The study will enroll approximately 34 pediatric patients in a staggered manner. The approach will be to first enroll Cohort 1 (12 to < 18 years of age) to collect safety data (including CV surveillance data), tolerability data, PK data and biomarker data for up to 52 weeks (EOS). Cohort 1 participants will be enrolled in a single group of 22 participants. Cohort 2 (2 to < 12 years of age) participants will be enrolled in 2 groups with a total 12 participants.
  • Follow-up Period (1 week): Participants who completed the Week 52 (EOS) visit and meet all the eligibility criteria may be enrolled in a rollover extension program (REP) in which they will receive open-label iptacopan. Participants who do not enroll in the REP or do not complete Day 1 of the REP within 7 days of the EOS, should be contacted 7 days after the EOS visit for AE and SAE monitoring and any AEs reported by the participant should be recorded in the study case report form (CRF).

What is being measured

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

  1. Log-transformed ratio to Baseline in UPCR (based on FMV)

    UPCR is measured based on the geometric mean of 2 FMVs obtained preceding each scheduled visit.

    Measured: Baseline, Week 38

Secondary outcomes (4)
  1. Pharmacokinetic Parameter Cmax in Plasma

    Cmax is the maximum (peak) observed plasma drug concentration after dose administration (mass x volume-1)

    Measured: Week 12 (Pre-dose (0), 2, 4, 6, and 8 hours post-dose)

  2. Pharmacokinetic Parameter AUClast in Plasma

    AUClast is the AUC from time zero to the last measurable concentration sampling time (tlast) (mass x time x volume-1)

    Measured: Week 12 (Pre-dose (0), 2, 4, 6, and 8 hours post-dose)

  3. Pharmacokinetic Parameter AUCtau in Plasma

    AUCtau is the AUC calculated to the end of a dosing interval (tau) at steady-state (amount x time x volume-1)

    Measured: Week 12 (Pre-dose (0), 2, 4, 6, and 8 hours post-dose)

  4. Ctrough concentrations

    Pre-dose drug concentration

    Measured: Week 4, Week 12 and Week 38

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing iptacopan in people with Primary Immunoglobulin A Nephropathy (IgAN), run by Novartis Pharmaceuticals at 20 sites in 8 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 9 inclusion and 15 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 9 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 20 sites in United States, Israel, Japan, Australia, China and 3 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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?

Log-transformed ratio to Baseline in UPCR (based on FMV) (time frame: Baseline, Week 38). 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 9 Sep 2026.
