- Safety and tolerability assessed by summary of Adverse Events (AEs), clinical lab assessments, physical exam results, and 12-lead ECGs for Parsaclisib as monotherapy and as a combination therapy [ Time Frame: Measured every 3 weeks for approximately 15 months ]
- Efficacy as measured by overall response rate [ Time Frame: Measured every 9 weeks for approximately 15 months ]
- Pharmacokinetic collections to determine Cmax, Tmax, Cmin, half-life [ Time Frame: Measured for each patient at Day 1, Day 8, and Day 15 ]
