Main Objective: To evaluate the safety, tolerability, preliminary efficacy and PK of multiple SC doses of APL-2 in subjects with Warm Antibody Autoimmune Hemolytic Anemia (wAIHA) or Cold Agglutinin Disease (CAD).;Secondary Objective: Exploratory objective: to evaluate the PD of multiple SC doses of APL-2 when administered to patients with Autoimmune Hemolytic Anemia (AIHA).;Primary end point(s): Incidence and severity of treatment emergent adverse events (TEAEs) following administration of multiple doses of subcutaneous (SC) APL-2.;Timepoint(s) of evaluation of this end point: This endpoint will be assessed at months 2, 3, 6, and 12.
