Outcome Measures
Primary Outcomes (1)
Safety of CD34+ Stem Cell Infusions Followed by LLME as Measured by 100-Day Mortality
Determine the safety of CD34+ stem cell infusions followed by the LLME treated CD34- fraction. This includes monitoring the patients for any side effects associated with the LLME treated cell infusion or any other unexpected adverse events. This regimen will be gauged as to its safety using 100 day mortality as the measured endpoint. Deaths from all causes will be included.
Through 100 days post-transplant or death
Secondary Outcomes (4)
Rate of Engraftment of Non-Myeloablative Transplants
Through 30 days post-transplant
Incidence of Grade II-IV Acute Graft-Versus-Host-Disease (GVHD)
Through 24 months post-treatment
Rate of Serious Infectious Complications
Through 3 months post-transplant
Number of Patients Who Achieve a CD4 Count > 200/Micro-liters
Through 60 Days Post Transplant
Study Arms (1)
LLME to Decrease GVHD Following HSC T
EXPERIMENTALTo determine if an experimental agent, LLME, can decrease the incidence and severity of Graft-Versus-Host-Disease (GVHD) following hematopoietic stem cell transplantation (HSCT).
Interventions
Infusion of L-leucyl-L-leucine methyl ester (LLME) treated donor white blood cells
Fludarabine 30 mg/m2 prior to HSCT infusion
Cytarabine 2gm/m2 prior to HSCT infusion
Cyclophosphamide 1gm/m2 prior to HSCT infusion
Tacrolimus given before and after HSCT infusion
Mesna 1gm/m2/day given prior to HSCT infusion.
GM-CSF given post HSCT infusion
CD34 selected allogeneic stem cell infusion with 5x104/kg untreated T cells
Eligibility Criteria
You may qualify if:
- Patients must be \> 18 years of age, with no upper age limit.
- Patients must have an ECOG performance status of 0 or 1.
- Any patient with a hematologic malignancy which is unlikely to be cured by conventional treatment is eligible for this study.
- Patients for whom a disease specific protocol exists will be transplanted on those protocols as discussed in the introduction.
- Patients who have had prior autografts may be treated on this protocol.
- Patients must have adequate physical function as measured by the following criteria:
- Cardiac: Asymptomatic or, if symptomatic, then left ventricular ejection fraction at rest must be \>40%.
- Hepatic: Aspartate transaminase (AST) micro 3x the upper limits of normal and total serum bilirubin \< 2.5 mg/dL. Patients with a higher bilirubin from "benign conditions" such as Gilbert's disease may still be eligible for the study.
- Renal: Serum creatinine within the normal range or if creatinine outside normal range then creatinine clearance \> 60 ml/min/1.73m2. Serum creatinine must be less than or equal to 2.0 mg/dl.
- Pulmonary: Asymptomatic or, if symptomatic, DLCO (diffusion capacity) \> 45% of predicted (corrected for hemoglobin)
- The patient or guardian(s) must be able to give informed consent to the study.
- Patient must have a suitable donor who is identical for HLA (human leukocyte antigens) -A, -B, -C, -DR. Single antigen mismatches for HLA-A, -B, -C, -DR are also permitted. Donors obtained through the National Marrow Donor Program (NMDP) will follow NMDP guidelines.
You may not qualify if:
- Patients who are eligible for a standard myeloablative transplant and for whom a standard myeloablative transplant is preferable will not be treated on this protocol.
