New hope for aHUS patients: Long-Term iptacopan study launches
NCT ID NCT05795140
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at the long-term safety and effectiveness of the drug iptacopan in people with a rare blood disorder called atypical hemolytic uremic syndrome (aHUS). Participants must have completed a previous iptacopan study and still benefit from the drug. The goal is to monitor side effects and see if the drug continues to control the disease over time.

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.
