Inclusion criteria
Inclusion criteria: 1. Ability to comprehend and willingness to sign a written ICF for the study. 2. Men or women, age = 18 years at the time of signing the ICF. 3. Diagnosis of primary wAIHA based on the presence of hemolytic anemia and serological evidence of anti-erythrocyte antibodies, detectable by the DAT positive for IgG only or IgG plus C3d. Note: Prior documentation of DAT testing is permitted. 4. Participants who were inadequately controlled with, were intolerant to, or have a contraindication to other therapies. There is no limit to the number of prior treatment regimens. 5. Hemoglobin = 7 to =65 years) yes F.1.3.1 Number of subjects for this age range 20
Exclusion criteria
Exclusion criteria: 1. Women currently pregnant or breastfeeding or participants expecting to conceive or father children within the projected duration of the study, starting with the screening visit through 90 days from the date of last dose of study drug. 2. A diagnosis of other types of AIHA; CAD, cold agglutinin syndrome, mixed-type AIHA or paroxysmal cold hemoglobinuria. 3. Warm AIHA suspected to be secondary to a lymphoproliferative malignancy or secondary to an autoimmune disease (eg, systemic lupus erythematosus, Castleman's disease, Sjögren's syndrome, or other). 4. A splenectomy less than 3 months before randomization. 5. Concurrent conditions or history of other diseases: a. History or clinical manifestations of significant unstable metabolic, hepatic, renal, hematological, pulmonary, cardiovascular, gastrointestinal, urological, neurological, or psychiatric disorders. b. Current or previous malignancy within 5 years of study entry, except basal or squamous cell skin cancer with removal considered to be curative, superficial bladder cancer, prostate intraepithelial neoplasm, carcinoma in situ of the cervix, or other noninvasive or indolent malignancy without sponsor approval. c. Clinically significant cardiac disease, including unstable angina, acute myocardial infarction, and/or cardiac conduction issues within 6 months of Day 1 visit. d. Current New York Heart Association Class II to IV congestive heart failure or uncontrolled arrhythmia. 6. Anti-phospholipid antibodies positive or elevated anti-streptolysin antibodies as assessed by the investigator as a clinical risk for thrombosis. 7. Hepatitis B (HBV) or hepatitis C (HCV) infection: Participants who are positive for the hepatitis B surface antibody or hepatitis B core antibody will be eligible if they are negative for HBV-DNA; these participants should be considered for prophylactic antiviral therapy. Participants who are positive for the anti-HCV antibody will be eligible if they are negative for HCV-RNA. 8. Known HIV infection or positivity on immunoassay. 9. History or presence of an abnormal ECG that, in the investigator's opinion, is clinically meaningful. Participants with screening QTc interval > 470 milliseconds for males and > 480 milliseconds for females (corrected by Fridericia) are excluded. In the event that a single QTcF is > 470 milliseconds for males or > 480 milliseconds for females, the participant may enroll if the average QTcF for 3 ECGs is < 470 milliseconds for males or < 480 milliseconds for females. 10. Use of the following medications: a. Treatment with rituximab within 3 months of the Day 1 visit. b. Use of immunosuppressive therapy within 28 days of the Day 1 visit. Immunosuppressive therapy includes, but is not limited to, cyclosporine A, azothioprine, mycophenolate mofetil, cyclophosphamide, or high-dose corticosteroids. Note: Participants receiving corticosteroids must be at a stable dose level = 20 mg/day (prednisone or equivalent corticosteroid dose) within 14 days of the Day 1 visit. c. Use of IVIG or epoetin alfa within 2 weeks of the Day 1 visit. d. Chronic or current active infectious disease requiring systemic antibiotics, antifungal, or antiviral treatment or exposure to a live vaccine within 30 days of the Day 1 visit. e. Use or expected use during the study of any prohibited medications, including potent CYP3A4 inhibitors or inducers, within 14 days or 5 half-lives (whichever is longer) before the Day 1 visit. 11. Current treatment or treatment with
