Prostatic Neoplasms, Castration-Resistant Clinical Trial
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)
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.

Primary | Optimal dose of TVB-2640 in combination with Enzalutamide, as determined by the maximum tolerated dose (MTD) | 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. | Day 28 | |
Secondary | Number of adverse events (evaluated using the NCI CTCAE v5.0) of different doses of TVB-2640 in combination with Enzalutamide | All observed AEs will be tabulated and reported as relative frequencies (i.e., fraction of patients with that AE). This will be done by AE and maximum grade experienced within a patient. The fraction of patients with each AE by grade will be estimated with a binomial point estimate and corresponding 95% binomial confidence interval (CI). AEs will be collected until 30 days following the last dose of study drug. AEs will be reported for each different dose of TVB-2640 given. | 12 months | |

Secondary | Prostate-Specific Antigen (PSA) Response Rate | The PSA response rate will be evaluated using PCWG3 criteria and defined as the proportion of patients with a PSA decline of at least 50%. Any change from baseline is confirmed by a second measurement at least 3 weeks later. PSA Response Rate will be evaluated using PCWG3 criteria and defined as following: Percentage change from baseline in PSA to 12 weeks post Enzalutamide plus TVB-2640. Only evaluate for patients with at least 12 weeks of treatment, the PSA assessment at 12 weeks (84 days +/-3 days) will be used; Maximum percent decrease in PSA from baseline that occurs at any point after treatment. | Baseline; 12 weeks | |
Secondary | Overall radiographic response rate | Tumor response will be evaluated using the PCWG3 criteria. Patients with measurable disease will be evaluated for clinical benefit as determined by tumor response using RECIST v1.1. Patients with non-measurable bone disease will be evaluated for progression based on the presence of any new lesions by bone scans. Radiographic tumor evaluation will be performed at screening and every 3 cycles or more frequently as determined by the investigator. Using the tumor response that is determined by the investigator, best overall response will be determined using RECIST v1.1. Best overall response is defined as the best response recorded from the start of treatment until disease progression or study exit. The overall response rate will be determined as the number of patients with a confirmed PR or CR divided by the total number of patients evaluable for overall response. | From baseline until disease progression for a maximum of 2 years from enrollment | |
Secondary | Overall median progression free survival (PFS) | Overall progression free survival (PFS) is determined using the PCWG3 criteria. Overall PFS is measured from screening until the time that disease progression (radiographic progressive disease or clinical deterioration) or death is documented, whichever occurs first. | From baseline until disease progression or death from any cause for a maximum of 2 years from enrollment | |
Secondary | Median radiographic progression free survival (PFS) as assessed by PCWG3 | Radiographic progression-free survival (rPFS) is determined using the PCWG3 criteria to assess both soft-tissue and bone assessments. The rPFS is measured from screening until the time the first radiographic scan shows disease progression, or until the time of death, whichever occurs first. Patients who do not progress radiographically or did not die prior to study exit are censored on the date of their last dose of Enzalutamide plus TVB-2640. PFS will be summarized with a Kaplan-Meier curve. The Kaplan-Meier estimator will be used to determine the 6-month and 12-month PFS rates. Each estimate will have a corresponding 95% confidence interval. The median PFS will also be estimated with a corresponding 95% confidence interval | From baseline until disease progression for a maximum of 2 years from enrollment |
