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 randomization, or without hematological response to the last course of B-cell depleting therapy * Neutrophils: \<1000/mm3 * Serum creatinine \>1.5 × upper limit of normal (ULN) * Immunoglobulin G (IgG) \<5g/L * Active viral, bacterial or other infections (including tuberculosis and SARS-CoV-2) requiring systemic treatment at time of screening, or history of recurrent clinically significant infection * 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 before randomization * History of splenectomy Other protocol-defined Inclusion/Exclusion may apply.
