PRIMARY OBJECTIVES:
I. To estimate the graft versus host disease (GVHD)-free relapse/progression-free survival (GRFS) at one-year post hematopoietic cell transplantation (HCT) and to evaluate the clinical activity of post-transplant high dose cyclophosphamide (PTCy).
SECONDARY OBJECTIVES:
I. To summarize toxicities/complications/infections including type, frequency, severity, attribution, time course and duration through 100 days post-transplant.
II. To estimate the cumulative incidence (CI) of acute and chronic GVHD. III. To characterize the time course of neutrophil and platelet recovery/engraftment.
IV. To estimate overall survival (OS), progression-free survival (PFS), CI of relapse/progression and non-relapse mortality (NRM) at 100 days, 1 year and 2 years.
V. To describe quality of life at 100 days, 6 months, 1 and 2 years. VI. To characterize immune cell reconstitution and T cell repertoire post high dose cyclophosphamide in mismatched donor HCT.
VII. To characterize quality of life.
OUTLINE:
CONDITIONING REGIMEN: Patients are assigned to 1 of 3 conditioning regimens at the discretion of the attending physician and principal investigator.
REGIMEN A (REDUCED INTENSITY CONDITIONING): Patients receive fludarabine phosphate intravenously (IV) over 60 minutes on days -7 to -3 and melphalan hydrochloride IV over 20 minutes on day -2.
REGIMEN B (MYELOABLATIVE CONDITIONING [MAC]): Patients receive fludarabine phosphate IV over 1-3 hours and busulfan IV over 3 hour on days -5 to -2.
REGIMEN C (MAC): Patients receive fludarabine phosphate IV over 60 minutes on days -7 to -5 and total body irradiation (TBI) twice daily (BID) on days -4 to -1.
TRANSPLANT: Patients undergo peripheral blood stem cell (PBSC) hematopoietic cell transplantation (HCT) on day 0.
GVHD PROPHYLAXIS: Patients receive cyclophosphamide IV over 1-2 hours on days 3-4, mycophenolate mofetil IV or orally (PO) thrice daily (TID) beginning on day 5 and stopping on day 35 if no severe GVHD is present, and tacrolimus IV continuously on days 5-180 with a taper beginning on day 90 in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up twice weekly for 100 days, twice monthly for 6 months, monthly until no evidence of GVHD, and then yearly for up to 2 years.

- GRFS [ Time Frame: From stem cell infusion to grade 3-4 acute graft versus host disease (GVHD), moderate-severe chronic GVHD, relapse, progression or death (from any cause), whichever occurs first, assessed for up to 2 years ]Estimates will be calculated using the Kaplan-Meier method, Greenwood formula will be used to calculate standard error (SE), and log-log transformation method will be used to construct 95% confidence intervals. Graft versus host disease (GVHD, acute and chronic), disease status and vital status will be monitored per clinical standard operating procedure. For this endpoint failure is defined as the first occurrence of grade 3 or 4 acute GVHD, or moderate/severe chronic GVHD, or disease relapse (for patients in complete remission at the start of conditioning) or disease progression (for patients with active disease at the start of conditioning) or death (from any cause). Patients not experiencing any of these will be censored at his/her date of last contact.
- Acute graft versus host disease (aGVHD) of grades 2-4 and 3-4 graded according to the Consensus Grading [ Time Frame: Up to 100 days post-stem cell infusion ]The first day of aGVHD onset at a certain grade will be used to calculate cumulative incidence curves for that GVHD grade. Relapse/death prior to onset will be considered competing events.
- Change in quality of life as assessed by SF-36, Functional Assessment of Cancer Therapy Bone Marrow Transplant questionnaire [ Time Frame: Baseline up to 2 years ]
- Change in quality of life as assessed by the MD Anderson Symptom Inventory questionnaire [ Time Frame: Baseline up to 2 years ]
- Change in quality of life as assessed by the PedsQL Stem Cell Transplant module [ Time Frame: Baseline up to 2 years ]
- Chronic graft versus host disease (cGVHD) graded according to the National Institutes of Health Consensus Staging [ Time Frame: Day 100 post-stem cell infusion up to 2 years ]The first day of cGVHD onset at a certain grade will be used to calculate cumulative incidence curves. Relapse/death prior to onset will be considered competing events.
- Cumulative incidence of relapse/progression [ Time Frame: From start of protocol therapy, assessed for up to 2 years ]Will be calculated as competing risks using the Gray method.
- Incidence of adverse events graded using the Common Terminology Criteria for Adverse Events (CTCAE) version 4.03 Toxicity Scale [ Time Frame: Up to 100 days post-stem cell infusion ]Will include the type, severity, and the probable association with the study regimen. Tables will be constructed to summarize the observed incidence by severity and type of toxicity.
- Incidence of adverse events graded using the Berman Toxicity Scale [ Time Frame: Up to 100 days post-stem cell infusion ]Will include the type and severity. Tables will be constructed to summarize the observed incidence by type of toxicity.
- Microbiologically documented infections [ Time Frame: Up to 100 days post-stem cell infusion ]Will be reported by site of disease, date of onset, severity and resolution.
- Non-relapse Mortality (NRM) [ Time Frame: From start of protocol therapy until non-disease related death, or last follow-up, whichever comes first, assessed for up to 2 years ]Will be calculated as competing risks using the Gray method.
- Overall Survival (OS) [ Time Frame: From start of protocol therapy to death, or last follow up, whichever occurs first, assessed for up to 2 years ]Estimates will be calculated using the Kaplan-Meier method, Greenwood formula will be used to calculate SE, and log-log transformation method will be used to construct 95% confidence intervals. Each patient's vital status will be monitored per clinical standard operating procedure. For this endpoint failure is defined as death (from any cause). Patients not experiencing a death event will be censored at his/her date of last contact.
- Progression Free Survival (PFS) [ Time Frame: From start of protocol therapy to death, relapse/progression, or last follow up, whichever occurs first, assessed for up to 2 years ]Estimates will be calculated using the Kaplan-Meier method, Greenwood formula will be used to calculate SE, and log-log transformation method will be used to construct 95% confidence intervals. Disease status and vital status will be monitored per clinical standard operating procedure. For this endpoint failure is defined as disease relapse (for patients in complete remission at the start of conditioning) or disease progression (for patients with active disease at the start of conditioning) or death (from any cause). Patients not experiencing any of these will be censored at his/her date of last contact.
- Time to hematological recovery in terms of neutrophil (absolute neutrophil count >= 500/ul, 1.0 x 10^3/ul) and platelet (20 x 10^3/ul and 100 x 10^3/ul) engraftment time [ Time Frame: Up to 2 years ]
