Dose Escalation Trial of Denileukin Diftitox (Ontak) Post Autologous Transplantation

Stopped early · Phase 1

Conditions studied: Multiple Myeloma

In brief

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.

Who can join

Age: 18 and older, up to 70. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• 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:
• Diagnosis of Multiple Myeloma
• Age >=18 and no more than 70 years.
• Able to understand and sign a consent form.
• Can collect peripheral blood stem cells with a CD34+ cell dose of at least 5.0 x 106/kg. The CD34 molecule is a Cluster of Differentiation molecule present on hematopoietic stem cells.
• Conditioning regimen to be high dose Melphalan at a dose of 200mg/m2.
• Karnofsky Performance Score (KPS) >60 or ECOG (Eastern Cooperative Oncology Group) performance status <=2
• Kidney function:Creatinine <2.0 mg/dl or creatinine clearance >50 ml/min
• Heart function: Ejection fraction >45%
• Liver function tests :Serum bilirubin, alanine aminotransferase (ALT), aspartate aminotransferase (AST) less than 3 X upper limit of normal
• Lung function tests: Forced Vital Capacity (FVC), Forced Expiratory Volume in One Second (FEV1) or Diffusing Capacity of the Lung for Carbon Monoxide (DLCO) >45% predicted

You may not qualify if…

• Age <18 years or > 70 years
• Previous exposure to denileukin diftitox.
• Patients with documented uncontrolled central nervous system (CNS) disease.
• Previous AHSCT.
• Significant organ dysfunction deemed to be inappropriate for autologous transplantation.
