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 anhydrovinblastine in treating patients
who have advanced recurrent solid tumors.
OBJECTIVES: I. Determine the maximum tolerated dose and assess the toxicity of
anhydrovinblastine in patients with advanced refractory solid tumors. II. Assess the safety,
pharmacokinetics, and efficacy of this treatment regimen in this patient population.
OUTLINE: This is a dose escalation study. Patients receive anhydrovinblastine IV over 1 hour
on day 1. Courses are repeated every 3 weeks. Treatment continues in the absence of disease
progression or unacceptable toxicity. The dose of anhydrovinblastine is escalated in cohorts
of 1-6 patients until the maximum tolerated dose (MTD) is determined. The MTD is defined as
the dose that at which no more than 2 of 6 patients experience dose limiting toxicity.
Patients are followed at 1 month after treatment, and then monthly until death.
PROJECTED ACCRUAL: Approximately 30 patients will be accrued for this study within 8 months.
