UCN-01 and Cisplatin in Treating Patients With Advanced or Metastatic Solid Tumors

OBJECTIVES:

• Determine the maximum tolerated dose of cisplatin when administered with UCN-01 in patients with advanced solid tumors.
• Assess the toxicity and potential antitumor activity of this regimen in these patients.
• Determine the pharmacokinetics of this regimen in these patients.

OUTLINE: This is a dose-escalation, multicenter study of cisplatin.

Patients receive cisplatin IV over 1 hour on day 1 and UCN-01 IV continuously over 36-72 hours beginning on day 2. Treatment continues every 4 weeks for a total of 6 courses in the absence of disease progression or unacceptable toxicity.

Cohorts of 1-6 patients receive escalating doses of cisplatin until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity.

Patients are followed every 2-3 months for at least 1 year.

PROJECTED ACCRUAL: A total of 9-30 patients will be accrued for this study within 1 year.
