Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Recruitment took place at an academic medical center.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Four screened subjects did not meet eligibility criteria. Forty subjects were enrolled, but one withdrew after randomization without receiving treatment, and is listed as a "non-completer". Thus, data are presented for 39 participants.

  Outcome Measures
  Show All Outcome Measures

1.  Primary:   Percentage of Participants With Response, Analyzed Per International Myeloma Working Group Response Criteria   [ Time Frame: Efficacy assessments will be made after the first two cycles of therapy (approximately 56 days--each cycle is 28 days) ]

2.  Primary:   Percentage of Participants With Response, Analyzed Per International Myeloma Working Group Response Criteria   [ Time Frame: After the initial efficacy assessment at the completion of cycle 2 (at approximately 56 days), efficacy assessments will be made after every other cycle (approximately every 56 days). ]

3.  Secondary:   To Compare the Effect of Continuous Versus Intermittent Regimens on F Actin Polymerization in Peripheral Blood Mononuclear Cells and Activation of Tumor Antigen-specific T Cells, as Well as Innate Lymphocytes (Natural Killer or Natural Killer T Cells).   [ Time Frame: Research blood draw will be obtained at baseline, and at 2-4 hr (on day 1), 1 wk, and 4 wk after initiation of cycles 1 and 2. ]

4.  Secondary:   To Correlate Drug Induced Changes in F Actin Polymerization With Adverse Effects and Clinical Responses.   [ Time Frame: Research bone marrow aspirate is obtained at baseline and after completion of 2 cycles of therapy (approximately 56 days) ]

5.  Secondary:   To Correlate Drug Induced Changes in F Actin With Cytokine Profile.   [ Time Frame: Research blood draw will be obtained at baseline, and at 2-4 hr (on day 1), 1 wk, and 4 wk after initiation of cycles 1 and 2. ]
