Reduced Intensity Conditioning Before Partially Matched Donor Stem Cell Transplant in Treating Patients With Advanced Cutaneous T Cell Lymphoma
Study Details
Study Description
Brief Summary
This phase I trial studies the side effects and the best dose of donor lymphocyte infusion when given together with reduced intensity conditioning regimen before partially matched donor stem cell transplant in treating patients with stage IIB-IV mycosis fungoides or Sezary syndrome. Giving chemotherapy and low-dose total-body irradiation followed by high-dose cyclophosphamide before a donor peripheral blood stem cell transplant helps stop the growth of cells in the bone marrow, including normal blood-forming cells (stem cells) and cancer cells. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells (called graft-versus-host disease). Removing the T-cells from the donor cells and giving them before transplant may stop this from happening. Additionally, giving tacrolimus and mycophenolate mofetil before and after transplant may also stop this from happening.

Detailed Description
PRIMARY OBJECTVES:
-
To evaluate regimen related toxicity, engraftment and graft versus host disease (GVHD) in the first 100 days with new reduced intensity haploidentical regimen protocol, including fludarabine (fludarabine phosphate), low dose total body irradiation, and cyclophosphamide.
-
To determine an effective donor lymphocyte infusion (DLI) dose that provides successful engraftment without causing GVHD.
SECONDARY OBJECTIVES:
-
To assess myeloid and lymphoid engraftment rates of patients undergoing treatment on this regimen.
-
To determine the incidence and severity of GVHD in patients undergoing treatment on this regimen using a combination of tacrolimus and mycophenolate mofetil (MMF) as GVHD prophylaxis.
-
To examine progression free survival and overall survival in patients with cytotoxic T-cell lymphoma (CTCL) undergoing treatment on this regimen.
-
To assess the pace of lymphoid recovery in this patient population.
OUTLINE: This is a phase I, dose-escalation study of DLI.
REDUCED INTENSITY CONDITIONING: Patients receive fludarabine phosphate intravenously (IV) over 30 minutes on days -11 to -8 and undergo total body irradiation twice daily (BID) on day -7. Patients also receive donor cluster of differentiation (CD)3+ enriched T lymphocyte infusion on day -6 and high-dose cyclophosphamide IV over 2 hours on days -3 to -2.
TRANSPLANT: Patients undergo allogeneic peripheral blood stem cell transplant (PBSCT) on day 0.
GVHD PROPHYLAXIS: Beginning on day -1, patients receive tacrolimus IV with taper (drug wean) by day 60 and mycophenolate mofetil IV BID on days -1 to 28 in the absence of GVHD.
After completion of treatment, patients are followed up periodically.

Outcome Measures
Primary Outcome Measures
- Rate of regimen-related toxicities [Up to 100 days post-transplant]
Estimate of dose-specific rates of toxicity will be presented with corresponding confidence intervals using the exact method. The method of Atkinson and Brown will be used for any rate related to definition of dose limiting toxicity, due to two-stage sampling.
- Rate for hematopoietic engraftment [Up to 100 days post-transplant]
Estimate of dose-specific rate for engraftment will be presented with corresponding confidence intervals using the exact method. The method of Atkinson and Brown will be used for any rate related to definition of dose limiting toxicity, due to two-stage sampling.
- Rate for immune reconstitution [Up to 100 days post-transplant]
Estimate of dose-specific rate for immune reconstitution will be presented with corresponding confidence intervals using the exact method. The method of Atkinson and Brown will be used for any rate related to definition of dose limiting toxicity, due to two-stage sampling.
- Incidence of GVHD [Up to 100 days post-transplant]
- Maximum tolerated dose of DLI, determined according to dose limiting toxicities [day -4]
Secondary Outcome Measures
- Myeloid engraftment rate [Up to 6 months post-transplant]
- Lymphoid engraftment rate [Up to 6 months post-transplant]
- Incidence of GVHD using tacrolimus and mycophenolate mofetil prophylaxis [Up to 6 months post-transplant]
- Progression free survival [Up to 6 months post-transplant]
Progression free survival will be estimated by the Kaplan-Meier method.
- Overall survival (OS) [Up to 6 months post-transplant]
OS will be estimated by the Kaplan-Meier method.
- Rate of lymphoid recovery [Up to 6 months post-transplant]
- Incidence of adverse events [Up to 6 months]
All estimates of dose-specific rates (e.g., toxicity) will be presented with corresponding confidence intervals using the exact method. The method of Atkinson and Brown will be used for any rate related to definition of dose limiting toxicity, due to two-stage sampling.
