NCT ID: NCT00577668

Last Updated: 2011-05-03

Basic Information

• Recruitment Status: WITHDRAWN
• Clinical Phase: PHASE2
• Study Classification: INTERVENTIONAL
• Study Start Date: 2007-04-30

Brief Summary

In this study, researchers want to find out if using the VTD regimen, along with higher doses melphalan, in subjects who have relapsed or progressed after previous transplant(s), can be given safely to subjects who have failed previous transplant(s).

Detailed Description

Autologous transplant is now considered a standard treatment for many patients with multiple myeloma. An autologous transplant is a procedure in which stem cells are removed from a patient and then given back to the patient following intensive treatment. Doctors remove healthy stem cells from a patient's circulating blood system and store them before the patient receives high-dose chemotherapy. The stem cells are then returned to the patient, where they can produce new blood cells to replace cells destroyed by the treatment. The drug usually used before transplant is melphalan alone in 1 or 2 high doses. In past studies conducted at UAMS, researchers have shown that a chemotherapy treatment regimen called "VTD" is effective in patients with multiple myeloma who have failed previous treatments. VTD is a combination of drugs consisting of VelcadeTM (also known as bortezomib), Thalidomide, and Dexamethasone. In this study, researchers want to find out if using the VTD regimen, along with higher doses melphalan, in subjects who have relapsed or progressed after previous transplant(s) can be given safely to subjects who have failed previous transplant(s).

Study Design

• Allocation Method: NON_RANDOMIZED
• Intervention Model: SINGLE_GROUP
• Primary Study Purpose: PREVENTION
• Blinding Strategy: NONE

Study Groups

VDT and Melphalan

To find out if three drugs, bortezomib, thalidomide, and dexamethasone in addition to high doses of melphalan (M-VTD) and autologous transplant can be given safely and effectively to subjects who have failed previous regimens with transplant(s).

Group Type: EXPERIMENTAL

Melphalan, Velcade, Thalidomide, Dexamethasone

Intervention Type: DRUG

To assess, in patients with one or two prior auto transplants, the efficacy of a high-dose combination chemotherapy with MEL 300 (in 3 fractions of 100 mg/m2 on days -7, -4, -1) plus VTD (Velcade = bortezomib 1.3 mg/m2 on days -7, -4, -1; Thalidomide 200 mg/d on days -1 through -7; Dexamethasone 40 mg on days -7, -6, -4, -3, -1, 0) followed by autologous peripheral blood stem cell (PBSC) infusion of a minimum dose of 3 million CD34 cells/kg.

Intervention Type: DRUG

Eligibility Criteria

Inclusion Criteria

• History of histologically documented MM with relapsed or progressive disease after either scheduled tandem or one autologous transplantation.
• Patient has measurable disease in which to capture response.
• Performance status of 2 as per Zubroid scale, unless PS of 3-4 based solely on bone pain.
• Patients must have a platelet count 75,000/μL, and an ANC of at least 1,000/μL.
• Patients must have adequate renal function defined as serum creatinine < 2.5 mg/dL.
• Patients must have adequate hepatic function defined as serum transaminases and direct bilirubin < 2 x the upper limit of normal.
• Pregnant or nursing women may not participate. Women of childbearing potential must have a negative pregnancy documented within one week of registration. Women of reproductive potential may not participate unless they have agreed to use an effective contraceptive method.
• Male or female adults of at least 18 years of age.
• Patients must have signed an IRB-approved written informed consent form and demonstrate willingness to meet follow-up schedule and study procedure obligations.

Exclusion Criteria

• Chemotherapy or radiotherapy received within the previous 2 weeks.
