E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To demonstrate that either dose of ianalumab induces durable hemoglobin response compared to placebo, in patients with wAIHA who failed at least one previous line of treatment |
|
E.2.2 | Secondary objectives of the trial |
Key secondary objective: 1- To demonstrate that either dose of ianalumab maintains durable hemoglobin response, that is sustained beyond the end of the treatment period, compared to placebo
Other secondary objectives: 2- To assess the time to durable response / response / complete response in each treatment group 3- To assess the quality of response in each treatment group (response, complete response, hemoglobin levels). 4- To assess the need for rescue treatments in each treatment group 5- To assess the safety profile of ianalumab 6- To characterize the pharmacokinetics (PK) of ianalumab 7- To assess B-cell levels at each treatment group 8- To assess immunoglobulin levels at each treatment group 9- To assess the immunogenicity of ianalumab 10- To assess the quality of life (QoL) in each treatment group |

E.3 | Principal inclusion criteria |
- 18 years and older at time of signing consent - Patients with primary or secondary wAIHA, as previously documented by a positive direct antiglobulin test (DAT) specific for anti-IgG or anti-IgA, who had an insufficient response to, or relapsed after at least one line of treatment, including patients with corticosteroid resistance, dependence or intolerance - Haemoglobin concentration ≥5 g/dL and <10g/dL, and presence of symptoms related to anemia at Screening and Week 1 - The dose of supportive care must be stable for at least 4 weeks prior to randomisation into the study
Other protocol-defined inclusion criteria may apply |

E.4 | Principal exclusion criteria |
-wAIHA secondary to haematologic disease involving bone marrow (e.g. CLL) or another disease requiring prohibited medication as per protocol. Patients with autoimmune diseases after wash-out from the treatments are allowed. - Presence of other forms of AIHA (cold or intermediate forms), Evans syndrome or other cytopenias. - Prior use of B-cell depleting therapy (e.g., rituximab) within 12 weeks prior to randomisation ; no hematologic response to the last course of Bcell depleting therapy. -Neutrophils: <1000/mm3 - Serum creatinine >1.5 x upper limit of normal (ULN) - Active viral, bacterial or other infections (including active or latent tuberculosis -TB or SARS-CoV-2) requiring systemic treatment at the time of screening, or history of recurrent clinically significant infections (e.g. bacterial infections with encapsulated organisms) - Positivity for hepatitis C virus, hepatitis B surface antigen (HBsAg), or hepatitis B core antibody (HBcAb).HBcAB positive patients can be enrolled if HBsAG negative, HBV DNA negative, no pre-existing liver fibrosis is present and antiviral prophylaxis is given. - Known history of primary or secondary immunodeficiency, or a positive human immune deficiency virus (HIV) test result - Live or live-attenuated vaccination within 4 weeks of randomisation - History of splenectomy
Other protocol-defined exclusion criteria may apply |

E.5 End points |
E.5.1 | Primary end point(s) |
