Atypical Hemolytic Uremic Syndrome Clinical Trial
Official title:
A Multi-center, Single Arm, Open-label Extension Study to Evaluate the Long-term Safety, Tolerability and Efficacy of Iptacopan in Participants With Atypical Hemolytic Uremic Syndrome (aHUS) Who Have Completed a Preceding Iptacopan Phase 3 Study in aHUS
This is a multicenter, single arm, open-label, extension study to evaluate the long-term safety, tolerability, and efficacy of iptacopan in participants with aHUS.

Eligibility | 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, 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. |

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Number of participants with adverse events and serious adverse events | Number of participants with adverse events and serious adverse events will be provided | Throughout the study duration, up to 4 years | |
Primary | Number of participants with abnormal safety laboratory parameters, vital signs and ECGs | Number of participants with abnormal safety laboratory parameters , vital signs and ECGs will be provided | Throughout the study duration, up to 4 years | |
Secondary | Number of participants with absence of aHUS relapse without the use of anti-C5 antibody | Atypical hemolytic uremic syndrome (aHUS) relapse is defined by the coexistence of at least two of the following at the same visit:
thrombocytopenia (platelet count < 150 x 109 /L), microangiopathic hemolytic anemia (hemoglobin < 10 g/dl, LDH > upper limit of normal, undetectable haptoglobin, presence of schistocyte on blood smear), worsening kidney function (serum creatinine or urine protein to creatinine ratio (UPCR) > upper limit of normal and an increase of = 15% compared to baseline levels) |
Throughout the study duration, up to 4 years | |
Secondary | Number of participants with complete TMA response status without the use of anti-C5 antibody therapy | Complete thrombotic microangiopathy (TMA) Response is defined as (1) hematological normalization in platelet count (platelet count =150 x 109/L) and LDH (below ULN), and (2) improvement in kidney function (= 25% serum creatinine reduction from baseline or = 25% serum creatinine reduction compared to serum creatinine values prior to initiation of anti-C5 antibody therapy) | Throughout the study duration, up to 4 years | |
Secondary | Estimated glomerular filtration rate (eGFR) | Estimated glomerular filtration rate (eGFR) based on eGFR categories will be collected.
Serum creatinine as measured in mg/dL as part of the clinical chemistry panel through the central laboratory will be used to calculate the eGFR applying the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formula. |
Throughout study duration, up to 4 years | |
Secondary | Chronic kidney disease (CKD) stage | Chronic kidney disease (CKD) stage (1-5) based on eGFR categories will be provided:
Stage 1 (G1): Kidney damage with normal kidney function Stage 2 (G2): Mild loss of kidney function Stage 3 (G3): 3a: Mild to moderate loss of kidney function; 3b: Moderate to severe loss of kidney function Stage 4 (G4): Severe loss of kidney function Stage 5 End stage renal disease (kidney failure): Kidney failure and need for transplant or dialysis |
Throughout study duration, up to 4 years | |
Secondary | Number of participants by dialysis requirement status | Dialysis requirement status will be provided | Throughout the study duration, up to 4 years | |
Secondary | Number of participants with Thrombotic Microangiopathy (TMA) related adverse events | TMA related events during the study defined as any of the following:
Irreversible (>3 months) reduction in eGFR rate by =20%, not attributable to another cause An episode of acute kidney injury (AKI) attributed to a TMA that requires renal replacement therapy A non-renal manifestation of a TMA that requires hospitalization, or causes irreversible organ damage or death. |
Throughout study duration, up to 4 years |
