Is this trial a fit for you?

Likely a good fit

Ideal candidates are individuals who have completed a prior Novartis-sponsored Phase 3 clinical trial of iptacopan for aHUS and are still benefiting from the treatment.

Probably not a fit

Patients currently receiving other complement inhibitors or those with significant comorbidities may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This multicenter, single-arm, open-label extension study aims to assess the long-term safety, tolerability, and efficacy of iptacopan in participants diagnosed with atypical hemolytic uremic syndrome (aHUS). Participants who have previously completed a Phase 3 clinical trial of iptacopan will continue treatment and be monitored through on-site visits every four months. The study includes a follow-up tele-visit to collect data on any adverse events after the last treatment. The goal is to gather comprehensive data on the long-term effects of iptacopan in this patient population.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the long-term management of aHUS, potentially improving patient outcomes.

How similar studies have gone: Other studies involving iptacopan have shown promise, indicating a potential for success in this extension study.

Show full inclusion / exclusion criteria
Inclusion Criteria:

1. Signed informed consent must be obtained prior to participation in the open label extension study
2. Willing and able to comply with the study Schedule of Activities
3. Participants who have completed the full study treatment period of any prior "Novartis sponsored" iptacopan Phase 3 clinical trial in aHUS (e.g. CLNP023F12301 , CLNP023F12302), are still on iptacopan study treatment and derive benefit from it as per Investigator's judgement
4. Prior vaccinations against Neisseria meningitidis, Streptococcus pneumoniae and Haemophilus influenzae infections should be up to date (i.e., any boosters required should be administered according to local guidelines)

Exclusion Criteria:

1. Concomitant treatment with any complement inhibitor as well as concomitant treatment with any of the prohibited drugs
2. Any comorbidity or medical condition (including but not limited to any active systemic bacterial, viral or fungal infection or malignancy) that, in the opinion of the Investigator could put the participant at risk
3. Active infection or history of recurrent invasive infections caused by encapsulated bacteria such as Neisseria meningitidis, Streptococcus pneumoniae or Haemophilus influenzae
4. History of hypersensitivity to iptacopan or its excipients or to drugs of similar chemical classes
5. Pregnant or nursing (lactating) women
6. Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, unless they are using effective methods of contraception during dosing of investigational drug and for 1 week after stopping of investigational drug.

Other protocol-defined inclusion/exclusion criteria may apply.
