Arm Intervention/treatment
Experimental: Treatment Arm
Subjects will receive ZN-d5 orally (PO), once daily (QD) on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
Drug: ZN-d5
ZN-d5 will be administered orally
Other Name: Study Drug

Primary Outcome Measures :
  1. Safety and Tolerability [ Time Frame: 18 Months ]
    Incidence and severity of adverse events (AEs), graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 5.0

  2. Dose limiting toxicities [ Time Frame: 18 Months ]
    Incidence of Dose-limiting toxicities (DLTs) observed in DLT evaluable subjects

Secondary Outcome Measures :
  1. PK Parameter: Finding max concentration (Cmax) of ZN-d5 [ Time Frame: 48 months ]
    Determine the maximum observed concentration (Cmax) of ZN-d5 collected in the plasma from subjects at different dose levels.

  2. PK Parameter: Finding time to maximum concentration (Tmax) of ZN-d5 [ Time Frame: 48 months ]
    The duration (in hours) it takes for ZN-d5 to reach the maximum concentration (or Cmax) collected in the plasma from subjects at different dose levels.

  3. PK Parameter: Finding half-life of ZN-d5 [ Time Frame: 48 months ]
    The time takes for half the drug concentration of ZN-d5 to be eliminated (Half-life) from the plasma that was collected from subjects at different dose levels

  4. PK Parameter: Finding the Area Under the Curve (AUC) of ZN-d5 [ Time Frame: 48 months ]
    The total exposure of ZN-d5 over time (AUC) from the plasma collected by the subject at different dose levels.

  5. Assess the hematologic response to ZN-d5 [ Time Frame: 48 months ]
    The number of Complete Response (CR), Very Good Partial Response (VGPR), Partial Response (PR), No Response (NR), Progressive Disease (PD) using the AL Amyloidosis Hematologic Response Criteria.

  6. Duration and time to hematologic response to ZN-d5 [ Time Frame: 48 months ]
    The rate of, duration of, and time to CR, modified Complete Response (mCR), CR+VGPR, and mCR+VGPR

Other Outcome Measures:
  1. To assess potential biomarker of ZN-d5 [ Time Frame: 48 months ]
    The number of peripheral B-Cells from blood tests
