- Number of Participants with any Adverse Event [ Time Frame: From first dose to within 28 days after the last dose ]Adverse Events evaluated by the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) v5.0
- Maximum plasma concentration (Cmax) [ Time Frame: Day 15, 16, 29, 43 and 47 in dose escalation phase and Day 15, 29, 43 and 57 in dose expansion phase ]Maximum plasma concentration (Cmax)
- Area under the concentration-time curve in a selected time interval (AUC0-t) [ Time Frame: Day 15, 16, 29, 43 and 47 in dose escalation phase and Day 15, 29, 43 and 57 in dose expansion phase ]Area under the concentration-time curve in a selected time interval (AUC0-t)
- Rate of Clinical Remission [ Time Frame: Day 1 to 8 weeks treatment ]Rate of Clinical Remission was defined as the proportion of patients who have platelet ≥30×10^9/L at week 8 and increased ≥20×10^9/L vs baseline without anti-ITP emergency treatment during the study
