PRIMARY OBJECTIVE:
I. To determine the optimal dose of anti-viral veto cells, defined as the dose which achieves engraftment without severe graft-vs-host disease (GVHD) at 42 days after non-myeloablative megadose T cell depleted haploidentical hematopoietic cell transplantation (HCT).
SECONDARY OBJECTIVES:
I. Toxicity. II. Response rate. III. Time to progression. IV. Infections. V. Immune reconstitution. VI. Overall survival up to 1 year.
OUTLINE: This is a dose-escalation study of cytokine-treated veto cells.
CONDITIONING REGIMEN: Patients receive anti-thymocyte globulin (ATG) intravenously (IV) over 4 hours on days -9 to -7 and fludarabine IV over 1 hour on days -6 to -3, then undergo total body irradiation (TBI) on day -1.
TRANSPLANT: Patients undergo peripheral blood stem cell transplantation (PBSCT) IV over 30-60 minutes on day 0.
GVHD PROPHYLAXIS: Patients receive cyclophosphamide IV over 3 hours on days +3 and +4 and cytokine-treated veto cells IV over 30-60 minutes on day +7.
After completion of stem cell transplant, patients are followed up once a week for 4 weeks, once a month for 3 months, and then periodically for one year.

- Optimal dose of donor-derived cytokine-treated veto cells [ Time Frame: Within 42 days of cytokine-treated veto cell infusion ]For the purpose of dose-finding, toxicity is defined as steroid resistant grade 3 or 4 graft-versus-host-disease (GVHD), or death from any cause, within 42 days of veto cell infusion.
- Efficacy of veto cells [ Time Frame: At day 42 post cytokine-treated veto cell infusion ]Efficacy is defined as the patient being alive and engrafted at day 42 post veto cell infusion.
- Incidence of adverse events [ Time Frame: Up to 1 year ]Unadjusted distributions of time-to-event outcomes will be estimated using the method of Kaplan and Meier and their relationship to prognostic covariates and veto cell dose level will be evaluated by Bayesian piecewise exponential survival regression.
- Response rate [ Time Frame: Up to 1 year ]Unadjusted distributions of time-to-event outcomes will be estimated using the method of Kaplan and Meier and their relationship to prognostic covariates and veto cell dose level will be evaluated by Bayesian piecewise exponential survival regression.
- Time to progression [ Time Frame: Up to 1 year ]Unadjusted distributions of time-to-event outcomes will be estimated using the method of Kaplan and Meier and their relationship to prognostic covariates and veto cell dose level will be evaluated by Bayesian piecewise exponential survival regression.
- Infections [ Time Frame: Up to 1 year ]Unadjusted distributions of time-to-event outcomes will be estimated using the method of Kaplan and Meier and their relationship to prognostic covariates and veto cell dose level will be evaluated by Bayesian piecewise exponential survival regression.
- Immune reconstitution [ Time Frame: Up to 1 year ]Unadjusted distributions of time-to-event outcomes will be estimated using the method of Kaplan and Meier and their relationship to prognostic covariates and veto cell dose level will be evaluated by Bayesian piecewise exponential survival regression.
- Overall survival [ Time Frame: Up to 1 year ]Unadjusted distributions of time-to-event outcomes will be estimated using the method of Kaplan and Meier and their relationship to prognostic covariates and veto cell dose level will be evaluated by Bayesian piecewise exponential survival regression.
