PRIMARY OBJECTIVES: I. To determine the maximum tolerated dose (MTD) of PS-341 (Velcade, Bortezomib) in combination with 17-allyamino-17-demethoxygeldanamycin (17-AAG) in patients with relapsed or refractory acute myeloid leukemia (AML) or acute lymphoblastic leukemia (ALL). II. To determine the MTD of PS-341 in combination with 17-AAG in patients with relapsed or refractory chronic lymphocytic leukemia (CLL), and non-Hodgkin's lymphoma (NHL). III. To define the specific toxicities and the dose limiting toxicity (DLT) of PS-341 in combination with 17-AAG in the treatment of patients with relapsed or refractory hematologic malignancies. SECONDARY OBJECTIVES: I. To determine the pharmacokinetics of 17-AAG alone and in combination with PS-341 in patients with AML, ALL, CLL, and NHL. II. To evaluate 20S proteasome inhibition following combination therapy with 17-AAG and PS-341 in patients with AML, ALL, CLL, and NHL. III. To assess the relationship between FLT3 mutational status and leukemic cell response to PS-341 and 17-AAG in patients with AML. IV. To assess the relationship between Bcl-2 over-expression and response to 17-AAG and PS-341 in patients with AML and NHL. V. To evaluate the effects of the combination of PS-341 and 17-AAG on Hsp90 and NF-kappaB and their downstream targets including Hsp70, Akt, phosphorylated Akt, p21, and caspases 3 and 9 in patient-derived primary AML and NHL cells. OUTLINE: This is a dose-escalation study. Patients are stratified according to diagnosis (acute myeloid leukemia \[AML\] or acute lymphoblastic leukemia vs chronic lymphoctyic leukemia or non-Hodgkin's lymphoma \[NHL\]). Patients receive 17-N-allylamino-17-demethoxygeldanamycin (17-AAG) intravenously (IV) over 1-6 hours on days 1, 4, 8, and 11 and bortezomib IV over 3-5 seconds on days 4, 8, and 11 of course 1 and on days 1, 4, 8, and 11 of all subsequent courses. Treatment repeats every 21 days for 3-12 courses provided patient is receiving clinical benefit. Patients achieving objective response may discontinue therapy to undergo stem cell transplantation.Cohorts of 3-6 patients with receive escalating doses of 17-AAG and bortezomib 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. After the MTD is determined, an additional 20 patients (10 per stratum with AML or follicular NHL) are enrolled and receive 17-AAG and bortezomib as above at the MTD.
