Phase I trial to study the effectiveness of geldanamycin analogue in treating patients who have advanced solid tumors or non-Hodgkin's lymphoma. Drugs used in chemotherapy work in different ways to stop tumor cells from dividing so they stop growing or die.
PRIMARY OBJECTIVES: I. To determine the maximum tolerated dose of geldanamycin analogue (AAG) in patients with advanced solid tumors. II. To determine the toxic effects of this drug in this patient population. III. To determine the biochemical and molecular effects of this drug in normal and accessible tumor tissue in these patients. IV. To determine the pharmacokinetics of this drug in these patients. V. To assess any antitumor activity of this drug in these patients. OUTLINE: This is a dose-escalation study. Patients receive geldanamycin analogue (AAG) IV over 1-6 hours once daily on days 1, 4, 15, and 18. Courses repeat every 4 weeks in the absence of disease progression or unacceptable toxicity. Cohorts of 3-6 patients receive escalating doses of AAG until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 6 patients experience dose-limiting toxicity. Once the MTD is determined, an additional 10 patients are treated at the MTD. Patients are followed every 6 weeks.

Maximum tolerated dose of tanespimycin
DLT are defined as any greater than or equal to grade 3 non-hematologic toxicity (except for alopecia of any grade, grade 3 nausea or vomiting during less than maximal antiemetic therapy, and grade 3 fever in the absence of neutropenia and infection), any grade 4 hematologic toxicity (except for anemia of any grade), or the inability to resume treatment by day 42 (longer than two week delay) because of drug related toxicity.
Time frame: 28 days
Biomolecular effects of tanespimycin in normal tissues such as peripheral blood and bone marrow mononuclear cells
Changes in the protein expression of the molecular markers will be assessed by western blot analysis.
Time frame: Up to day 5
Pharmacokinetics of tanespimycin
Determined by HPLC with photodiode array detection. The pharmacokinetic parameters that will be determined for parent drug include the maximum plasma concentration (Cmax), time of maximum plasma concentration (Tmax), area under the concentration-time curve (AUC), terminal half-life, clearance and volume of distribution.
Time frame: Pre-infusion, 20 minutes, 40, 50, 60 (end of infusion), 70, 80, 95 and 110 minutes, and 2.5, 3, 4, 5, 6.5, 8, 10, 14 and 24 hours
