Phase I Dose Escalation Study to Evaluate the Safety of T138067-Sodium in Patients With Advanced Refractory Cancer
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die.
PURPOSE: Phase I trial to study the effectiveness of T138067 sodium in treating patients with advanced refractory cancer.
OBJECTIVES: I. Determine the maximum tolerated dose of T138067 sodium that can be given to patients with advanced refractory cancer on a 28-day schedule and establish a dose for further study. II. Evaluate the safety and dose limiting toxicity of T138067 sodium in these patients. III. Determine the pharmacokinetic parameters after a single intravenous dose of this agent in these patients. IV. Obtain safety data and preliminary efficacy information after repetition of single doses of T138067 sodium in these patients.
OUTLINE: This is an open label, dose escalation study. Patients receive T138067 sodium by IV over 3 hours. Patients may be retreated every 4 weeks for up to 6 courses (6 months total) in the absence of disease progression or dose limiting toxicity (DLT). At least 3 patients are treated at each dose level in the absence of DLT. The maximum tolerated dose is defined as the dose level where 2 of 3-6 patients experience DLT.
PROJECTED ACCRUAL: Approximately 3-24 patients will be accrued into this study.

PATIENT CHARACTERISTICS: Age: 18 and over Performance status: Karnofsky 60-100% Life expectancy: Greater than 3 months Hematopoietic: Absolute neutrophil count at least 1,500/mm3 Platelet count at least 100,000/mm3 Prothrombin time at least 30% of control Partial thromboplastin time at least 30% of control Hepatic: Bilirubin less than 2 mg/dL ALT and AST no greater than 2 times normal Alkaline phosphatase no greater than 2 times normal Renal: Creatinine less than 1.5 mg/dL OR Creatinine clearance at least 60 mL/min Cardiovascular: No New York Heart Association class III or IV heart disease No myocardial infarction in the past 6 months Other: No immunodeficiency syndrome (acquired or congenital) No uncontrolled infection No significant comorbidity that may compromise participation in this study Not pregnant Effective contraception required of all fertile patients during and until 3 months after study
