Rebeccamycin Analog and Cisplatin With or Without Filgrastim in Treating Patients With Advanced Cancer

National Cancer Institute (NCI)40 enrolled

Overview

Phase I trial to study the effectiveness of rebeccamycin analog and cisplatin with or without filgrastim in treating patients who have advanced cancer. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. Colony-stimulating factors such as filgrastim may increase the number of immune cells found in bone marrow or peripheral blood and may help a person's immune system recover from the side effects of chemotherapy.

OBJECTIVES: I. Determine the maximum tolerated doses of a rebeccamycin analogue and cisplatin with or without filgrastim (G-CSF) in patients with advanced malignancies. II. Determine the qualitative and quantitative toxicities of these regimens in these patients. III. Determine if the pharmacokinetics of a rebeccamycin analogue are affected by cisplatin and if there are sequence dependent pharmacokinetic effects. IV. Assess any antitumor effects of this regimen in these patients. OUTLINE: This is a dose-escalation, multicenter study of a rebeccamycin analogue and cisplatin. Part I (previously untreated or minimally pretreated patients): The first patient of each cohort receives cisplatin IV over 1 hour followed 2 hours later by a rebeccamycin analogue IV over 1 hour on day 1. The second patient in the same cohort receives the same drugs in the reverse order. The drug sequence for each additional patient within the same cohort is alternated with reference to the preceding patient. During each subsequent course, the study drugs are administered to each patient in the reverse order as compared to the prior course. Treatment repeats every 3 weeks for 4 courses in the absence of disease progression or unacceptable toxicity. Dose escalation is initially performed without filgrastim (G-CSF). Cohorts of 4-6 patients receive escalating doses of a rebeccamycin analogue and cisplatin until the maximum tolerated dose (MTD) of each drug is determined. The MTD is defined as the highest dose at which less than 2 of 6 patients experience dose limiting toxicity (DLT). If 2 of the first 6 patients experience DLT, then dose escalation proceeds in combination with G-CSF treatment. Patients receive G-CSF subcutaneously daily beginning on day 2 and continuing until blood counts have recovered for 2 days or until approximately day 15. Cohorts of 4-6 patients receive escalating doses of a rebeccamycin analogue and cisplatin as above. The MTD is defined as above. Part II (heavily pretreated patients): Heavily pretreated patients receive a rebeccamycin analogue and cisplatin starting at 2 dose levels preceding the MTD from part I. Patients are followed for at least 30 days.
