Brief Summary:
This is a single-center, open-label (sequential-group dose-escalation dose-finding) phase I study of satraplatin and docetaxel in patients who have received prior chemotherapy regimens. Once the MTD is determined, an additional 6 patients, all with chemotherapy-naïve HRPC, will be enrolled. Once a recommended dose(s) (RD(s)) for phase 2 studies has/have been determined, 6 additional patients with chemotherapy-naïve HRPC will be enrolled at the RD to further evaluate safety and efficacy.

Tumors Prostate Cancer Drug: Satraplatin Phase 1

Detailed Description:

RATIONALE:

Satraplatin is an oral platinum analog that is currently being evaluated in combination with prednisone in a phase III clinical trial in patients with HRPC who have progressed following one prior chemotherapy regimen.

Docetaxel is a taxane that is indicated for the treatment of patients with non-small cell lung, breast, and prostate cancers. Specifically, it was recently approved in combination with prednisone for the treatment of patients with hormone refractory prostate cancer (HRPC). Docetaxel administered every 3 weeks was associated with a survival advantage versus mitoxantrone. Docetaxel administered weekly showed an improvement in survival versus mitoxantrone that was not statistically significant. However, it was better tolerated than docetaxel administered every 3 weeks, with significantly less grade 3 and 4 toxicities, especially neutropenia. The combination of satraplatin and weekly docetaxel may be a feasible regimen for patients with chemotherapy-naïve HRPC and for patients with other malignancies for which these medications show activity.

OBJECTIVE:

The objective of this study is to determine the optimum doses for satraplatin and weekly docetaxel when the 2 drugs are given in combination.

Drug Information available for: Docetaxel


Intervention Details:
  • Drug: Satraplatin
    Satraplatin is an oral platinum analogue that has shown promising activity in multiple tumor settings. Satraplatin (40 to 80 mg/m2/day) will be administered orally on days 1 to 5 of a 21 day cycle.


Primary Outcome Measures :
  1. To assess the maximum tolerated dose (MTD) of satraplatin administered every 4 weeks in combination with docetaxel administered weekly (3 of 4 weeks) [ Time Frame: 30 days ]

Secondary Outcome Measures :
  1. To assess safety and tolerability (as per NCI-CTCAE version 3.0) [ Time Frame: 30 days ]
  2. To assess preliminary antitumor activity [ Time Frame: 6 months ]
