An Early Phase 1 interventional study of Cyclophosphamide and Filgrastim in Primary Myelofibrosis and Secondary Myelofibrosis, sponsored by M.D. Anderson Cancer Center. Completed at 1 site in United States. Open to participants aged 18 Years to 70 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2020-10-14.

This early phase I trial studies the side effects of combination chemotherapy, total body irradiation, and donor blood stem cell transplant in treating patients with primary or secondary myelofibrosis. Drugs used in chemotherapy, such as melphalan, fludarabine phosphate, cyclophosphamide, tacrolimus, mycophenolate mofetil, and filgrastim work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high energy x-rays to kill cancer cells and shrink tumors. Giving combination chemotherapy and total body irradiation before a donor blood stem cell transplant helps to stop the growth of cells in the bone marrow, including normal blood-forming cells (stem cells) and cancer cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets.
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.

A 0–100 scale of how well someone can carry out everyday activities. 100 is no complaints and no signs of illness; 70 is able to look after yourself but not to work or keep up normal activity; 50 is needing considerable help and frequent medical care.
Studies often ask for 60 or 70 and above. Your doctor gives the score.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
How quickly the kidneys clear creatinine, a waste product, from the blood. A study may estimate it from a blood test with age, weight and sex (often by the Cockcroft–Gault formula), or measure it using blood and urine collected over a set time. Given in mL/min; higher is better.
The share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.
Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.
Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).
Karnofsky performance status (KPS)
