velcade®-beam and autologous hematopoietic stem cell transplantation for non-hodgkin's lymphoma, or mantle cell lymphoma

Conditions: Non-hodgkin's Lymphoma; Mantle Cell Lymphoma

Summary: this is a phase i/ii trial designed to study the toxicity and maximum tolerated dose (mtd) of bortezomib in combination with beam (carmustine (bcnu), etoposide, cytarabine, melphalan) and autologous hematopoietic stem cell transplantation (asct) and to obtain a preliminary estimate of the response rate to this combination.

primary objective:the primary objective of the study is to evaluate the toxicity and determine the maximum tolerated dose (mtd) of bortezomib when added to a standard beam (carmustine (bcnu), etoposide, cytarabine, melphalan) conditioning regimen followed by autologous hematopoietic stem cell transplantation (asct). secondary objective: the secondary objective of the study is to obtain a preliminary estimate of the overall response rate (orr), progression free survival (pfs), and overall survival (os) with this regimen. enrolled subjects will receive bortezomib in combination with beam (carmustine (bcnu), etoposide, cytarabine, melphalan) and autologous hematopoietic stem cell transplantation (ahsct). phase i treatment will administer bortezomib in four dose cohorts,in addition to the beam and asct. three patients will be accrued in each dose cohort with enrollment starting at dose cohort. these subjects will be evaluated to establish the maximum tolerated dose of bortezomib in combination with beam autologous peripheral blood stem cell transplantation. once established, the maximum tolerated dose will be utilized in treating an additional 20 subjects. follow-up: data collected will be utilized to obtain a preliminary estimate of the overall response rate, progressions free survival and overall survival using this regimen.
