A Phase 2 Study of Ianalumab in Adults With Primary Immune Thrombocytopenia (ITP) and Warm-antibody Autoimmune Hemolytic Anemia (wAIHA) Who Have Previously Benefited From Ianalumab.
This study is intended to explore the efficacy and safety of a second course of ianalumab after experiencing treatment failure in the pivotal Primary Immune Thrombocytopenia (ITP) trials (CVAY736I12301, CVAY736Q12301) and after loss of durable response in the pivotal Warm Autoimmune Hemolytic Anemia (wAIHA) trial (CVAY736O12301).
• Signed informed consent obtained prior to participation in the study.
• Male or female participants aged 18 years and older on the day of signing informed consent
⁃ Primary ITP patients:
• Previously enrolled and treated either with ianalumab/placebo in addition to first-line corticosteroids on protocol CVAY736I12301 or with ianalumab/placebo in addition to eltrombopag in the second line on protocol CVAY736Q12301, and who experienced treatment failure (TF) by parent trial definition ≥ 2 years after the last infusion of ianalumab/placebo
• Rescue medication and/or bridging therapy are allowed to be started within the 28 days prior to screening; platelet count results obtained prior to the start of the therapy must be used to assess eligibility and have to be collected within 30 days prior to screening
⁃ For Primary or Secondary wAIHA patients:
• Previously documented by a positive direct antiglobulin test (DAT) specific for anti-IgG or anti-IgA, previously enrolled and treated with ianalumab/placebo in blinded cohort or placebo followed by crossover to open label ianalumab in protocol CVAY736O12301, having experienced durable response lasting beyond 2 years from the last infusion of ianalumab/placebo in blinded cohorts or a durable response beyond week 20 from last dose of first course of ianalumab in the crossover arm.
• Relapsed wAIHA with hemoglobin concentration ≥5 g/dL and \<10 g/dL and presence of symptoms related to anemia during screening or within 14 days before screening window or within 28 days before screening window if rescue medication/bridging therapy has been initiated.
• Rescue medication and/or bridging therapy are allowed to be started during the screening and within 28 days prior to screening; hemoglobin level result for eligibility assessment needs to be obtained prior to the start of the treatment within 30 days prior to screening
• Supportive care is allowed in the case the participant received it in the parent trial when the relapse occurred and has remained stable at least 4 weeks prior screening
