Inclusion Criteria

Dose Escalation:

Have histologically confirmed, locally advanced, and unresectable cancer, or metastatic cancer and have progressed on or were intolerant to standard treatments or refused standard of care (SOC).

Dose Expansion:

Have documented histologically or cytologically confirmed adenocarcinoma of the prostate with documented PTEN loss or loss of function mutation, who have metastatic castration-resistant disease and have:

  • Disease progression per the Prostate Cancer Clinical Trials Working Group 3 (PCWG3)/modified RECIST 1.1 after the most recent regimen.
  • Received androgen receptor directed therapy previously with or without chemotherapy consisting of no more than 2 prior taxane-based regimens.
  • Been receiving androgen deprivation therapy with serum testosterone <50 ng/dL (<2.0 nM). Note: previously documented PTEN loss or loss of function mutation from archived tissue sample testing or cfDNA sample testing is acceptable if done in a CLIA certified lab or a locally certified lab.

Have an ECOG score of 0 or 1 Dose Escalation (Part 1): Have no measurable or measurable disease per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1.

Dose Expansion (Part 2): Have measurable or no measurable disease per PCWG3/modified RECIST 1.1

β€’ No more than 30 patients with no measurable disease will be enrolled in Dose Expansion (Part 2).

Exclusion Criteria
  • Participating in medical research not compatible with this study
  • Have not discontinued or recovered from previous treatments for cancer
  • Have a significant cardiac condition
  • Have untreated brain metastases
  • Have a primary brain tumor
  • Have a serious concomitant disorder
  • Unable to swallow or digest pills
  • Poorly controlled diabetes
  • Concomitant medications or substances that are strong inhibitors/inducers of CYP3A.Study

Primary Outcome Measures
NameTimeMethod
Dose Limiting Toxicities (DLTs)Baseline through Cycle 1 (28-day cycle)

Number of participants with DLTs during cycle 1

rPFS rateBaseline through measured progressive disease (estimated up to 12 months)

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.

Secondary Outcome Measures
NameTimeMethod
Disease Control Rate (DCR) per PCWG3/mRECIST1.1Baseline through progressive disease or date of death for any causes, whichever comes first, assessed up to 12 months.

DCR: Percentage of participants who exhibit stable disease (SD), PR or CR.

Safety and TolerabilityFrom screening to 30 days after last dose

All adverse events (AEs) per CTCAE v5.0.

Pharmacodynamic: biochemical effects of TAS0612: Total proteinsCycle 1 Day 1 through Cycle 1 Day 15 (28-day cycle)

Total proteins will be measured in blood samples collected at different time points.

Radiographic Progression Free Survival (rPFS) per PCWG3/mRECIST1.1Baseline through progressive disease or date of death for any causes, whichever comes first, assessed up to 6 months.

Proportion of patients experiencing a radiographic progression by PCWG3/mRECIST1.1 criteria

Duration of Response (DOR) per PCWG3/mRECIST1.1Baseline through progressive disease or date of death for any causes, whichever comes first, assessed up to 12 months.

DOR: Date of PR or CR to date of objective progression or death due to any cause.

Pharmacokinetics (PK) parameters including but not limited to: CmaxCycle 1 Day 1 through Cycle 1 Day 15 (28-day cycle) Cycle 2 Day 1 and Cycle 3 Day 1

time of TAS0612 it takes to reach Cmax.

Pharmacokinetics (PK) parameters including but not limited to: TmaxCycle 1 Day 1 through Cycle 1 Day 15 (28-day cycle) Cycle 2 Day 1 and Cycle 3 Day 1

time of TAS0612 it takes to reach Cmax,

Pharmacokinetics (PK) parameters including but not limited to: T1/2.Cycle 1 Day 1 through Cycle 1 Day 15 (28-day cycle) Cycle 2 Day 1 and Cycle 3 Day 1

time it takes for plasma concentration to fall by half its original value (t1/2) of TAS0612

Pharmacodynamic: molecular effects in tumor tissue of TAS0612Baseline through Day 1 Cycle 2 (28-day cycle) through study completion, an average of 1 year

Selected phospho-proteins will be analyzed in tumor tissue at baseline and on-treatment in dose escalation. The levels/changes of the phospho-proteins will be assessed and reported for target modulation.

Overall Response Rate (ORR) per PCWG3/mRECIST1.1Baseline through progressive disease or date of death for any causes, whichever comes first, assessed up to 12 months.

Proportion of patients experiencing a best overall response of Complete Response (CR) or Partial response (PR)

Prostatic Specific Antigen (PSA) ResponseBaseline to PSA progression, up to 12 months

Proportion of patients with β‰₯50% reduction in PSA from baseline to lowest post-baseline result.

Pharmacokinetics (PK) parameters including but not limited to: AUC.Cycle 1 Day 1 through Cycle 1 Day 15 (28-day cycle) Cycle 2 Day 1 and Cycle 3 Day 1

Area under the plasma concentration curve of TAS0612.

Pharmacodynamic: biochemical effects of TAS0612: phospho-proteinsCycle 1 Day 1 through Cycle 1 Day 15 (28-day cycle)

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.
