Clinical trial: Chemotherapy in Treating Patients With Refractory Advanced Solid Tumors or Hematologic Cancer

Summary: RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die.
  PURPOSE: This phase I trial is studying the side effects and best dose of 17-N-allylamino-17-demethoxygeldanamycin in treating patients with refractory advanced solid tumors or hematologic cancers.

Detailed description: OBJECTIVES:
  -  Determine the maximum tolerated dose of 17-N-allylamino-17-demethoxygeldanamycin (17-AAG) in patients with refractory or advanced solid tumors or hematologic malignancies.
  -  Evaluate the effects of this drug on the expression of signaling proteins present on an individual patient's cancer at the start of treatment and, if possible, post treatment.
  OUTLINE: This is a two-phase, dose-escalation, multicenter study. Patients are stratified according to disease (chronic myelogenous leukemia [CML] or Philadelphia chromosome [Ph]+ acute lymphoblastic leukemia [ALL] vs solid tumor).
  Patients receive 17-N-allylamino-17-demethoxygeldanamycin (17-AAG) IV over 60-90 minutes twice weekly. Courses repeat every 12 weeks in the absence of disease progression (after at least 2 courses for CML or Ph+ ALL patients) or unacceptable toxicity.
  -  Accelerated phase: Single patients receive escalating dose levels of 17-AAG until one patient experiences a first course grade 3 or greater toxicity or two different patients experience grade 2 toxicity during any course.
  -  Standard phase: Cohorts of 3-6 patients in each stratum receive escalating doses of 17-AAG 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.
  PROJECTED ACCRUAL: Approximately 51 patients will be accrued for this study.
