Outcome(s)

Primary OutcomePercentage of subjects who met all of the following criteria for improvement at Week 12 1. The primary symptom, lymphoproliferation/enterocolitis/cytopenia, most of which require therapeutic intervention at screening, is PR or CR; no other symptom is PD. 2. No new onset of lymphoproliferation, enterocolitis, or cytopenia that were not present at screening
Secondary Outcome-Improvement rate Week 24, Week 36, and Week 52 -CR rates and CR+PR rates for all symptoms at each assessment point. -CR rates and CR+PR rates for each symptom at each assessment point. -Improvement rate in other autoimmune symptoms at each assessment point. -Correlations between the Assessment of Quality of Life (EQ-5D-5L) and the Assessment of Efficacy. -Percentage of subjects who successfully tapered off steroids at 12, 24, and 52 weeks of treatment Percentage change in the volume of hepatomegaly and splenomegaly at each evaluation time point (if hepatomegaly and splenomegaly are to be evaluated)
