OBJECTIVES: Primary * Determine the maximum tolerated dose of 17-dimethylaminoethylamino-17-demethoxygeldanamycin (17-DMAG) in patients with an advanced malignant solid tumor or lymphoma. * Determine the dose-limiting toxic effects and toxicity profile of this drug in these patients. Secondary * Compare the effects of this drug on heat shock protein 90 (Hsp90) client proteins when assayed in peripheral blood mononuclear cells (PBMC) vs tumor tissue from patients treated with this drug. * Correlate disturbances in key signaling pathways with administration of this drug in these patients. * Determine the dose that alters key proteins in the majority of patients treated with this drug. * Correlate serum proteomic patterns with target interactions or DMAG clinical effects in patients treated with this drug. * Determine the pharmacokinetics of this drug in these patients. OUTLINE: This is a single-center, dose-escalation study. Patients receive 17-dimethylaminoethylamino-17-demethoxygeldanamycin (17-DMAG) IV over 1-2 hour on days 1 and 4 or days 2 and 5 weekly for 4 weeks. Treatment repeats every 4 weeks in the absence of disease progression or unacceptable toxicity. Cohorts of 1-6 patients receive escalating doses of 17-DMAG until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of up to 6 patients experience dose-limiting toxicity. Once the MTD is determined, 10 additional patients are treated at the MTD. PROJECTED ACCRUAL: Approximately 40 patients will be accrued for this study within 2 years.

Protocol

This section provides details of the study plan, including how the study is designed and what the study is measuring.
Design Details

40 patients to be enrolled

Total number of participants that the clinical trial aims to recruit.

Treatment Study

These studies test new ways to treat a disease, condition, or health issue. The goal is to see if a new drug, therapy, or approach works better or has fewer side effects than existing options.

Eligibility

Researchers look for people who fit a certain description, called eligibility criteria: person's general health condition or prior treatments.
