Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Pharmacokinetics (PK): Metabolites in plasma	Structure elucidation of TAS0612 metabolites in human plasma.	Cycle 1 Day 1 (each cycle is 28 days).
Other	Time-matched plasma exposures of TAS0612 and changes from baseline in QTcF using central ECG measurements	To explore the correlation between the incidence of exposures of TAS0612 in plasma and QT prolongation	Baseline through progressive disease or date of death for any causes, whichever comes first, assessed up to 12 months
Other	Exploratory correlation of tissue and/or blood markers with tumor efficacy endpoints and/or tumor resistance to TAS0612	To investigate potential predictive biomarkers for TAS0612.	Baseline through progressive disease or date of death for any causes, whichever comes first, assessed up to 12 months.
Other	Exposure of TAS0612 and selected efficacy and safety measures.	To explore the correlation between PK and antitumor activity or toxicity	Baseline through progressive disease or date of death for any causes, whichever comes first, assessed up to 12 months.
Primary	Dose Limiting Toxicities (DLTs)	Number of participants with DLTs during cycle 1	Baseline through Cycle 1 (28-day cycle)
Primary	rPFS rate	Percentage of participants with partial response (PR) or complete response (CR) at 6 months Prostate Cancer Working Group 3 (PCWG3)/ modified defined by the Response Evaluation Criteria in Solid Tumors (mRECIST) v1.1.	Baseline through measured progressive disease (estimated up to 24 months)
Secondary	Disease Control Rate (DCR) per PCWG3/mRECIST1.1	DCR: Percentage of participants who exhibit stable disease (SD), PR or CR.	Baseline through progressive disease or date of death for any causes, whichever comes first, assessed up to 12 months.
Secondary	Duration of Response (DOR) per PCWG3/mRECIST1.1	DOR: Date of PR or CR to date of objective progression or death due to any cause.	Baseline through progressive disease or date of death for any causes, whichever comes first, assessed up to 12 months.
Secondary	Radiographic Progression Free Survival (rPFS) per PCWG3/mRECIST1.1	Proportion of patients experiencing a radiographic progression by PCWG3/mRECIST1.1 criteria	Baseline through progressive disease or date of death for any causes, whichever comes first, assessed up to 6 months.
Secondary	Overall Response Rate (ORR) per PCWG3/mRECIST1.1	Proportion of patients experiencing a best overall response of Complete Response (CR) or Partial response (PR)	Baseline through progressive disease or date of death for any causes, whichever comes first, assessed up to 12 months.
Secondary	Prostatic Specific Antigen (PSA) Response	Proportion of patients with =50% reduction in PSA from baseline to lowest post-baseline result.	Baseline to PSA progression, up to 12 months
Secondary	Pharmacokinetics (PK) parameters including but not limited to: Cmax	time of TAS0612 it takes to reach Cmax.	Cycle 1 Day 1 through Cycle 1 Day 15 (28-day cycle) Cycle 2 Day 1 and Cycle 3 Day 1
Secondary	Pharmacokinetics (PK) parameters including but not limited to: Tmax	time of TAS0612 it takes to reach Cmax,	Cycle 1 Day 1 through Cycle 1 Day 15 (28-day cycle) Cycle 2 Day 1 and Cycle 3 Day 1
Secondary	Pharmacokinetics (PK) parameters including but not limited to: AUC.	Area under the plasma concentration curve of TAS0612.	Cycle 1 Day 1 through Cycle 1 Day 15 (28-day cycle) Cycle 2 Day 1 and Cycle 3 Day 1

Secondary	Pharmacodynamic: biochemical effects of TAS0612: Total proteins	Total proteins will be measured in blood samples collected at different time points.	Cycle 1 Day 1 through Cycle 1 Day 15 (28-day cycle)
Secondary	Pharmacodynamic: biochemical effects of TAS0612: phospho-proteins	Phospho-proteins will be measured in blood samples collected at different time points. The levels/changes (dose- and concentration-dependent) of phospho-proteins will be assessed and reported for biochemical effects of TAS0612.	Cycle 1 Day 1 through Cycle 1 Day 15 (28-day cycle)
