This is a Phase 1, open-label study that will evaluate the safety and tolerability of FT-7051 and determine the recommended Phase 2 dose (RP2D) as well as pharmacokinetics (PK), preliminary anti-tumor activity, and pharmacodynamics (PD) of FT-7051 in men with metastatic castration-resistant prostate cancer who have progressed despite prior therapy and had been treated with at least one potent anti-androgen therapy.
The starting dose, 25 mg once daily (QD), of FT-7051 administered discontinuously (21 days on/7 days off) in 28-day cycles.

Experimental: Dose escalation study of FT-7051 |
Drug: FT-7051
Dose levels: Dose Level -1 through Dose Level 7, assigned per the protocol using a BOIN design. Additional dose levels may be explored as applicable. Capsules available in strengths of 10mg, 25mg, and 100 mg that are orally administered per the protocol frequency and dose level. |
- Incidence of dose limiting toxicities (DLTs) [ Time Frame: Within first 4 weeks of treatment ]
- Serious adverse events (SAEs) and clinically relevant adverse events (AEs) [ Time Frame: The treatment duration, predicted average 26 weeks ]
- Incidence of clinical laboratory abnormalities as assessed by CTCAE v5.0 [ Time Frame: The treatment duration, predicted average 26 weeks ]
- Prostate-specific antigen (PSA): Percent Change from Baseline [ Time Frame: 12 weeks ]
- Prostate-specific antigen (PSA): Maximum Decrease from Baseline [ Time Frame: The treatment duration, predicted average 26 weeks ]
- Prostate-specific antigen (PSA): Time to Progression [ Time Frame: The treatment duration, predicted average 26 weeks ]
- Time to radiographic progression (rTTP) [ Time Frame: The treatment duration, predicted average 26 weeks ]
- Overall response rate: radiographic response rate [ Time Frame: The treatment duration, predicted average 26 weeks ]
- Complete response rate [ Time Frame: The treatment duration, predicted average 26 weeks ]
- Area under the plasma concentration versus time curve (AUC) [ Time Frame: Blood samples for PK analysis collected at multiple visits during the first 90 days of treatment ]
- Peak Plasma Concentration (Cmax) [ Time Frame: Blood samples for PK analysis collected at multiple visits during the first 90 days of treatment ]
- Time of peak plasma concentration (Tmax) [ Time Frame: Blood samples for PK analysis collected at multiple visits during the first 90 days of treatment ]
- Terminal elimination half-life (T 1/2) [ Time Frame: Blood samples for PK analysis collected at multiple visits during the first 90 days of treatment ]
- Apparent plasma clearance (CL/F) [ Time Frame: Blood samples for PK analysis collected at multiple visits during the first 90 days of treatment ]
- Apparent volume of distribution (Vd/F) [ Time Frame: Blood samples for PK analysis collected at multiple visits during the first 90 days of treatment ]
- Model-based estimate of change from baseline QT interval corrected using Fridericia's correction formula (QTcF) and 90% confidence interval at the estimated Cmax [ Time Frame: Electrocardiogram collected at multiple timepoints during the first 45 days of treatment ]
