Combination Chemotherapy, Total Body Irradiation, and Donor Blood Stem Cell Transplant in Treating Patients With Primary or Secondary Myelofibrosis
A Pilot Study of Reduced Intensity HLA-Haploidentical Hematopoietic Cell Transplantation With Post-Transplant Cyclophosphamide in Patients With Advanced Myelofibrosis

Detailed Description
PRIMARY OBJECTIVE:
I. To evaluate the safety and tolerability of reduced-intensity (FM) haploidentical hematopoietic cell transplantation (Haplo-HCT) followed by post-transplant cyclophosphamide (PTCy) in patients with advanced myelofibrosis (MF), as assessed by the evaluation of toxicities, including type, frequency, severity, attribution, time course and duration.
SECONDARY OBJECTIVES:
I. To summarize and evaluate hematologic (neutrophil and platelet) recovery. II. To estimate graft failure-free survival (GFS) at 100-days post-transplant. III. To estimate overall survival (OS), progression-free survival (PFS) and cumulative incidence (CI) of relapse/progression, and non-relapse mortality (NRM) at 100-days, 1-year, and 2-year post transplant.
IV. To estimate the cumulative incidence of acute graft-versus-host disease (GvHD), grade II-IV, at 100-days post-transplant (per Keystone Consensus modification of the Glucksberg criteria).
V. To estimate the cumulative incidence of chronic GvHD at 1-year and 2-year post transplant (per National Institute of Health [NIH] Consensus Criteria).
VI. To characterize the severity and extent of acute and chronic GvHD.
OUTLINE:
Patients receive melphalan intravenously (IV) over 30 minutes on days -5, fludarabine phosphate IV over 1 hour on days -5 to -2. Patients undergo total body irradiation (TBI) on day -1 and hematopoietic stem cell transplant (HCT) on day 0. Patients then receive cyclophosphamide IV over 1-2 hours on days 3 and 4. Beginning on day 5, patients receive tacrolimus IV continuously for approximately 2 weeks, then orally (PO) for 6 months followed by a taper, mycophenolate mofetil PO thrice daily (TID) until day 100, and filgrastim subcutaneously (SC) daily from day 7 until continued until absolute neutrophil count (ANC) > 1,500/mm^3 for 3 consecutive days. Treatment continues in the absence of disease progression or unexpected toxicity.
After completion of study treatment, patients are followed up at 1, 3, 6, 9, 12 and 24 months.

Description
Inclusion Criteria:
- Diagnosis of primary or secondary Myelofibrosis with transplant indication by DIPSS-plus (> intermediate -1);
- Age 18-70; patients >/= age 50 must have an comorbidity score (HCT-CI) </= 4 (Sorror). The Principal Investigator is the final arbiter for comorbidity;
- Patients can be in chronic phase (CP) with BM blast count </= 10% or after progression to AML and achieved </= 5% BM blasts (morphologic CR prior to transplant);
- Lack of an HLA matched donor or need to proceed fast to transplantation when a patient does not have an immediately available matched unrelated donor (typed by high-resolution in the registry);
- Performance status >/=70% (Karnofsky); patients > 50 years should have adequate cognitive function; any concerns regarding cognitive function should be addressed by a Geriatrician/Neurologist;
- Adequate organ function: ALT/AST/billirubin </= 5X UNL, creatinine clearance > 50mls/min (calculated with Cockroft-Gault formula); LVEF >/= 50%, DLCOc >/= 50%;
- Prior treatment with JAK2 inhibitor therapy is not excluded. Patients on a JAK2 inhibitor may continue through conditioning until Day -3 then tapered at the discretion of the investigator.
Exclusion:
Evidence of portal hypertension with varices, ascites, or hepatic encephalopathy;
->10% bone marrow blasts at transplant if no history of AML and >5% if had previous progression to AML;
- HIV positive; active hepatitis B or C;
- Patients with active infections. The PI is the final arbiter of the eligibility;
- Liver cirrhosis;
- Prior CNS involvement by tumor cells;
- Severe pulmonary hypertension (PHT) (On echo or right side cardiac catheterization);
- History of another primary malignancy that has not been in remission for at least 3 years (the following are exempt from the 3-year limit: non-melanoma skin cancer, fully excised melanoma in situ [Stage 0], curatively treated localized prostate cancer, and cervical or breast carcinoma in situ on biopsy or a squamous intraepithelial lesion on PAP smear);
- Positive Beta HCG test in a woman with child bearing potential defined as not post-menopausal for 12 months or no previous surgical sterilization;
- Noncompliance - Inability or unwillingness to comply with medical recommendations regarding therapy or follow-up, including smoking tobacco. Smoking cessation is a standard teaching practice prior to admission for all patients undergoing stem cell transplant. Any patient who refuses to stop smoking prior to transplant will not be eligible for this study.
