A Safety, Pharmacokinetic and Pharmacodynamic Study of Kevetrin in Patients With Advanced Solid Tumors
A Phase 1, Open-Label, Dose-Escalation, Safety, Pharmacokinetic and Pharmacodynamic Study of Kevetrin (Thioureidobutyronitrile) Administered Intravenously, in Patients With Advanced Solid Tumors
調査の概要
詳細な説明
Kevetrin was found to be effective in pre-clinical studies of human xenograft tumor models and was reasonably well-tolerated at therapeutic doses in the non-clinical animal studies. Kevetrin was also effective in multi-drug resistant tumor models; therefore, Kevetrin has the potential to treat tumors that have become resistant to standard chemotherapy. This trial will determine tolerance in humans and, possibly, efficacy with a Phase I, open-label, dose-escalation, safety, pharmacokinetic, and pharmacodynamic study of Kevetrin, in adult patients with solid tumors.
The primary objectives are the following:
- To determine the maximum tolerated dose (MTD) of Kevetrin.
- To determine the dose limiting toxicities (DLT) of Kevetrin.
- To establish a safe dose level of Kevetrin that can be used for future studies.
The secondary objectives are to determine the following:
- The pharmacokinetics of Kevetrin in humans.
- Observe for evidence of antitumor activity following administration of Kevetrin.
- If Kevetrin induces changes in the biomarker p21 in peripheral blood lymphocytes.
- If there is a pharmacodynamic relationship between the plasma concentrations of Kevetrin and a clinical or cellular effect.
During each 4 week cycle, each patient will receive three weekly doses of Kevetrin given as a 1 hour intravenous infusion followed by a 1 week off-treatment period. Following each dose, each patient will be monitored. If the patients have acceptable safety and tolerance, Kevetrin will be given once weekly for a total of 3 weeks. During each cycle patients will be evaluated for safety, tolerance, and Dose-Limiting Toxicity (DLT) that occur during a cycle.

Maximum Tolerated Dose (MTD) of Kevetrin
時間枠：up to 6 months
|
A dose will be declared the MTD if at least 1 patient out of 6 patients experience a dose limiting toxicity (DLT) at the highest dose level below the maximally administered dose. Once an MTD has been established, up to 12 additional patients may be enrolled at the MTD dose level for confirmation of safety. The maximally administered dose is if 1 or more of 6 patients experience a DLT. |

Pharmacokinetic Profile of Kevetrin
時間枠：Day 1 Pre-dose, 30 minutes after starting the infusion, 1 hr, 1 hr 10 min, 1 hr 20 min, 1 hr 30 min, 1 hr 45 min, 2 hr, 2 hr 30 min, 3 hr, 4 hr, 5 hr, 7 hr, and 24 hr after the initiation of the infusion
|
The pharmacokinetics (PK) of Kevetrin will be determined for all patients enrolled in the study on Day 1 of Cycle 1 and Day 15 of Cycle 2. Blood samples will be obtained before dosing, 30 minutes after starting the infusion, 1 hr, 1 hr 10 min, 1 hr 20 min, 1 hr 30 min, 1 hr 45 min, 2 hr, 2 hr 30 min, 3 hr, 4 hr, 5 hr, 7 hr, and 24 hr after the initiation of the infusion. The pharmacokinetic profile will be analyzed by standard noncompartmental methods to provide estimated values of the pharmacokinetic parameters and associated variables, such as area under the plasma concentration versus time curve (AUC) and peak plasma concentration (Cmax) of Kevetrin. Associations between pharmacokinetic variables and drug-related toxicities will be evaluated. |
