Multiple Myeloma
Conditions
Brief summary
The primary goal of this study is to determine the feasibility and safety of giving two doses of denileukin diftitox (DD) at days 0 and 21 post autologous stem cell transplantation in a dose escalation fashion. Secondary goals include evaluating the the effect of DD on the number and percentage of T-regs in the peripheral blood post transplant at each dose level, the effect of DD on T cell (CD4/CD8) reconstitution post transplant at each dose level and determining the time to engraftment: absolute neutrophil count (\>0.5 x 10\^9/L for 3 consecutive days), and platelet (\>20X 10\^9/L for 3 consecutive days). The hypothesis for the study is based on the ability of DD to deplete T-regs and subsequently enhance the immune reconstitution and reverse post transplant lymphopenia. This may indirectly enhance the efficacy of autologous transplantation and reduce disease relapse.
Interventions
After receiving their stem cell transplant on Day 0, participants will receive study agent via a 30 minute infusion. Participants will also receive a 30 minute infusion of study agent on Day 21. Follow-up visits for clinical assessment, blood draws for routine clinical laboratory studies and for immuno-correlative studies will also take place on days 42, 90, 180 and 360.

Eligibility
Inclusion criteria
All patients age \> =18 who have been diagnosed with Multiple Myeloma and are scheduled for autologous peripheral blood hematopoietic stem cell transplant (AHSCT) will be screened for eligibility. Patients must fulfill all of the following inclusion criteria to be eligible for this study: 1. Diagnosis of Multiple Myeloma 2. Age \>=18 and no more than 70 years. 3.
