Primary Outcome Measures:
  • Pharmacokinetic disposition of ATG after a 7.5 mg/kg/course [ Time Frame: 100 days ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Development of graft-versus-host disease [ Time Frame: 100 days ] [ Designated as safety issue: No ]
  • CD3, CD4, and CD8 recovery [ Time Frame: 12 months ] [ Designated as safety issue: No ]
    CD3, CD4, CD8 recovery at 1, 3, 6, 12 months post HSCT is routinely done to evaluate T-cell reconstitution.

  • Development of EBV-related complications [ Time Frame: 100 days ] [ Designated as safety issue: No ]

Enrollment: 30
Study Start Date: November 2009
Study Completion Date: January 2014
Primary Completion Date: January 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Thymoglobulin
Thymoglobulin 7.5 mg/kg/course prior to HSCT
Biological: Thymoglobulin (rATG)

Thymoglobulin 2.5 mg/kg of body weight IV administered daily for 3 days prior to HSCT.

Thymoglobulin infused over a minimum of 6 hours for the first infusion and over at least 4 to 6 hours on subsequent days of therapy.

Other Name: Anti-thymocyte Globulin (Rabbit)

Detailed Description:

Allogeneic hematopoeitic stem cell transplantation (HSCT) is a therapeutic option for patients with malignancies as well as metabolic and genetic diseases. Conditioning regimens given prior to donor cell infusion aim to ablate the recipient bone-marrow, to allow engraftment of the stem-cells infused, and to prevent acute versus host disease (aGVHD). Anti-thymocyte globulin (ATG) is one of the immunosuppressive drugs given as a preparative regimen for HSCT. Subjects will be given an ATG infusion daily for 3 days prior to HSCT and serum levels will be collected, as per schedule, with the last sample taken +100 days post-HSCT.
