Chemotherapy and Amifostine in Treating Patients With Recurrent or Refractory Solid Tumors
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Chemoprotective drugs, such as amifostine, may protect normal cells from the bad side effects of chemotherapy.
PURPOSE: Randomized phase I trial to study the effectiveness of amifostine in treating patients who are receiving chemotherapy for recurrent or refractory solid tumors.
Drug/Agent Toxicity by Tissue/Organ
Unspecified Adult Solid Tumor, Protocol Specific
Drug: amifostine trihydrate
Drug: gemcitabine hydrochloride
|Study Design:||Primary Purpose: Supportive Care|
|Official Title:||Phase I Study of Amifostine (Ethyol) as a Cytoprotector of Gemcitabine/Cisplatin Combination|
|Study Start Date:||August 1997|
|Primary Completion Date:||April 2001 (Final data collection date for primary outcome measure)|
OBJECTIVES: I. Evaluate the ability of amifostine to facilitate increased dose escalation of gemcitabine and cisplatin. II. Compare the dose limiting toxicities of gemcitabine and cisplatin administered with and without amifostine in these patients. III. Determine the maximum tolerated dose of gemcitabine and cisplatin administered with amifostine in these patients. IV. Determine whether synergy is produced by administering gemcitabine and cisplatin on the same day.
OUTLINE: This is a two stage study. The first stage is a randomized study, and the second stage is a dose escalation study. In the first stage of the study, patients receive either intravenous gemcitabine/amifostine/cisplation (GAP) or gemcitabine/cisplatin (GP) in the first cycle. Patients are administered the other arm in the second cycle. In the second stage of the study (dose escalation), the initial dose of GP or GAP is given on days 1 and 8 every 28 days. Dose escalation is carried out in cohorts of 3 patients per dose level. If 1 of 3 patients experiences dose limiting toxicity (DLT), then 3 more patients are accrued at the same dose level. The maximum tolerated dose (MTD) is defined as the lowest dose at which 2 of 6 or 2 of 3 patients experience DLT. Patients experiencing grade 3 or 4 toxicity or tumor progression are removed from the study. Patients will be reassessed every 12 weeks.
PROJECTED ACCRUAL: A total of 32 patients will be accrued over 12-24 months in the first stage of this study, and 9-12 patients will be accrued for the second stage..
