研究组 & 干预措施
Treatment Arm
Subjects will receive ZN-d5 orally (PO), once (QD) on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
干预措施: ZN-d5 (Drug)
结局指标
主要结局
Dose limiting toxicities
时间窗: 18 Months
Incidence of Dose-limiting toxicities (DLTs) observed in DLT evaluable subjects
Safety and Tolerability
时间窗: 18 Months

- PK Parameter: Finding the Area Under the Curve (AUC) of ZN-d5(48 months)
- Duration and time to hematologic response to ZN-d5(48 months)
- PK Parameter: Finding time to maximum concentration (Tmax) of ZN-d5(48 months)
- PK Parameter: Finding half-life of ZN-d5(48 months)
- Assess the hematologic response to ZN-d5(48 months)
