Official Title: A Phase I, Open-Label, Dose-Finding Study of TVB-2640 Administered in Combination With Enzalutamide (Xtandi) in Men With Metastatic Castration-Resistant Prostate Cancer (mCRPC)

Brief Summary: The purpose of this study is to determine what effects (good and bad) Enzalutamide and TVB-2640 have in the treatment of prostate cancer whose prostate cancer has spread to other parts of their body and that has not gotten better with previous treatment.
This study is a Phase I clinical trial.
Phase I clinical trials test the side effects of an investigational drug or an investigational combination with another drug.
"Investigational" means that the drug is still being studied and research doctors are trying to find out more about it.
Although Enzalutamide is already being used to treat men with prostate cancer, combining Enzalutamide with TVB-2640 together in patients with prostate cancer is considered experimental.
This research study is being done because additional effective treatments are needed for prostate cancer that has spread and is growing despite hormone suppression.
By doing this study, the investigators hope to learn if combining Enzalutamide with TVB-2640 can be done safely.
Participation in this research will last about 12 to 24 months after enrollment.

Detailed Summary: This phase I, open-label, dose-escalation study is designed to evaluate the dose limiting toxicities (DLTs) and maximum-tolerated dose (MTD) of TVB-2640 plus Enzalutamide and establish the TVB-2640 dose recommended for further investigation in phase 2 (i.e., recommended phase 2 dose [RP2D]).
Patients with a confirmed histological or cytological diagnosis of prostate cancer (PC), evidence of metastatic PC on imaging (bone scan and/or CT/MRI scan), serum testosterone <50 ng/dl, who had progressed on androgen-depletion therapy (ADT), with documented progressive metastatic castration-resistant prostate cancer (mCRPC) based on Prostate Cancer Working Group 3 (PCWG3) criteria and no previously treatment with cytotoxic chemotherapy are eligible.
This study represents the first clinical evaluation of TVB-2640 in combination with Enzalutamide.
All patients will receive Enzalutamide monotherapy at the approved dose of 160 mg once daily for 28 days to reach the steady state as determined by measuring Enzalutamide and des-methyl-Enzalutamide levels.
Participants who complete the Enzalutamide run-in period will begin oral TVB-2640 at the dose of 100 mg.
The dose escalation scheme will be the Bayesian optimal interval (BOIN) design with additional dose levels of 100 mg, 150mg, 200 mg, 250 mg, and 300mg daily.
The maximum sample size for the phase I will be 30 patients and the target DLT rate is 25% or less and a maximum of 9 patients at any dose level.

Current Primary Outcome: The maximum tolerated dose (MTD) is defined as the highest dose level at which ?1 patient experiences a dose-limiting toxicity, as defined in the protocol (DLT).
Once all the patients are accrued, the MTD will be determined by performing isotonic regression on the pooled data.
