Outcomes

Primary Outcome Measures

Secondary Outcome Measures

Mean change from Baseline to Week 13 in hematologic parameters of interest (Hgb for AIHA; PLT for ITP) in the intent to treat (ITT) population
Mean change from Baseline over time in hematologic parameters of interest (Hgb for AIHA; PLT for ITP)
Proportion of patients with a response at Week 13
Proportion of patients over time with a response
Time to response
Proportion of patients over time with loss of response
Proportion of patients over time with sustained response
Mean change from Baseline over time in Hct
Mean change from Baseline over time in Lactate Dehydrogenase (LDH)
Change from Baseline over time in Patient Global Assessment scores
The PtGA is a visual analog scale (VAS) ranging from 0 to 100. Patients will provide a global rating of their disease, for the day of the visit, in response to the statement "Considering all the ways that your disease affects you, please rate how you are feeling today by clicking or tapping on the line:" using a 100-point VAS where 0 is "very good, no symptoms" and 100 is "very poor, very severe symptoms."
For AIHA: Proportion of patients with an Hgb >12 g/dL or 2 g/dL higher than Baseline at W13
For AIHA: Number of blood transfusions and units of blood administered over time
For ITP: Number of platelet transfusions and units of platelets administered over time
