Brief summary

This pilot phase I trial studies the side effects of total bone marrow and lymphoid irradiation and how well it works with cyclophosphamide in treating patients with acute myeloid leukemia. Total marrow and lymphoid irradiation targets cancer in bone marrow and blood, instead of applying radiation to the whole body. Giving total bone marrow and lymphoid irradiation before a donor transplant helps stop the growth of cells in the bone marrow, including normal blood-forming cells (stem cells) and cancer cells. Drugs used in chemotherapy, such as cyclophosphamide, 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. Giving total bone marrow and lymphoid irradiation before donor transplant and cyclophosphamide after transplant may work better at treating acute myeloid leukemia.

Detailed description

PRIMARY OBJECTIVE: I. To evaluate the safety/feasibility of combining a total marrow and lymphoid irradiation (TMLI) transplant conditioning regimen with a post-transplant high dose cyclophosphamide (PTCy)-based graft versus host disease (GvHD) prophylaxis strategy, through the assessment of: adverse events: type, frequency, severity, attribution, time course, duration and complications: including acute GvHD, infection and delayed neutrophil/platelet engraftment. SECONDARY OBJECTIVES: I. To estimate the cumulative incidence (CI) of acute GvHD at 100 days post allogeneic hematopoietic cell transplantation (alloHCT). II. To estimate the CI of chronic GvHD at 6 months, 1- and 2-years post alloHCT. III. To estimate GVHD-free relapse-free survival (GRFS) at 1- and 2-years post alloHCT. IV. To describe the kinetics of immune reconstitution and T cell repertoire in the first year post alloHCT. V. To estimate overall survival (OS), relapse-free survival (RFS) and CI of relapse, and non-relapse mortality (NRM) at 100 days, 1- and 2-years post alloHCT. VI. To characterize quality of life using 36-Item Short Form Health Survey (SF-36), Functional Assessment of Cancer Therapy-Bone Marrow Transplant (FACT-BMT), and M. D. Anderson Symptom Inventory (MDASI) or Pediatric Quality of Life Inventory (PedsQL) at 100 days, 6 months, 1- and 2-years post alloHCT. VII. To assess bone marrow cellularity from bone marrow samples. VIII. To assess the clonogenic potential of cells from bone marrow samples. IX. To assess stromal damage from bone marrow samples. X. To evaluate cytokines and oxidative stress markers. OUTLINE: This is a dose-escalation study of TMLI. Patients undergo TMLI twice daily (BID) on days -4 to 0, then undergo bone marrow or peripheral blood stem cell transplant on day 0. Patients receive cyclophosphamide intravenously (IV) over 2 hours on days 3 and 4, tacrolimus given by continuous intravenous infusion (CIV) on days 5-90, and filgrastim beginning on day 5 until absolute neutrophil count (ANC) is at least 1,500/mm\^3 for 3 consecutive days. After completion of study treatment, patients are followed for up to 24 months.

Design outcomes

Primary

MeasureTime frameDescription
1a. Incidence of adverse eventsUp to 24 monthsAssessed using Bearman Scale Regimen-Related Toxicity scale. Scale range: Grade 0-4 (increasing grade reflects increasing severity), where Grade 0-none/did not experience and Grade 4=death.
1b. Incidence of adverse eventsUp to 24 monthsAssessed using National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.03 scale. Scale range: Grade 1-5 (increasing grade reflects increasing severity), where Grade 1 reflects a more milder form of the adverse event and Grade 5=death.

Secondary

MeasureTime frameDescription
Time to neutrophil and platelet recovery/engraftmentFrom day 0 to recovery or declaration of engraftment failure, assessed up to 24 months
Acute graft versus host disease (GvHD)Day 0 to 100 (120) days post-transplantGraded according to the Consensus Grading. The first day of acute GvHD 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. Will be calculated using the competing risk method as described by Gooley et al. (1999).
Chronic GVHDFrom day (80) 100 to the onset of chronic GvHD, death or last contact, whichever comes first, assessed up to 24 monthsThe first day of chronic GvHD onset will be used to calculate cumulative incidence curves, with relapse/death prior to onset considered competing events. Will be calculated using the competing risk method as described by Gooley et al. (1999).
GvHD-free/relapse-free survival (GRFS)From start of treatment (hematopoietic stem cell transplant [HCT]) to grade 3-4 acute GvHD, chronic GvHD requiring systemic treatment, relapse, or death (from any cause), whichever occurs first, assessed p to 24 monthsWill be calculated using the Kaplan-Meier method.
Levels of immune cellsUp to 24 monthsWill be measured by flow cytometry for cell subsets: a. T-cells.
Overall survivalFrom start of treatment until death, or last follow-up, whichever comes first, assessed up to 24 monthsWill be calculated using the Kaplan-Meier method.
Relapse-free survivalFrom the start of treatment to the date of death, disease relapse, or last follow-up whichever occurs first, assessed up to 24 monthsWill be calculated using the Kaplan-Meier method.
RelapseFrom start of therapy, assessed up to 24 monthsWill be calculated using the competing risk method as described by Gooley et al. (1999).
Non-relapse mortality (NRM)From start of treatment until non-disease related death, or last follow-up, whichever comes first, assessed up to 24 monthsThe cumulative incidence of NRM will be calculated reflecting relapse as a competing risk. Will be calculated using the Kaplan-Meier method and the competing risk method as described by Gooley et al. (1999).
Quality of life -QuestionnaireUp to 24 monthsAssessed using a. 36-Item Short Form Health Survey (SF-36). The SF-36 consists of eight scaled scores, which are the weighted sums of the questions in their section. Each scale is directly transformed into a 0-100 scale on the assumption that each question carries equal weight. The lower the score the more disability. The higher the score the less disability i.e., a score of zero is equivalent to maximum disability and a score of 100 is equivalent to no disability. The eight sections are: * a1. vitality * a2. physical functioning * a3. bodily pain * a4. general health perceptions * a5. physical role functioning * a6. emotional role functioning * a7. social role functioning * a8. mental health
Quality of life-Function AssessmentUp to 24 monthsAssessed using b. Functional Assessment of Cancer Therapy-Bone Marrow Transplant (FACT-BMT). (FACT-BMT) is a 47-item, valid and reliable measure of five dimensions of quality of life in bone marrow transplant patients. The dimensions collected and assessed are: * b1.physical well being * b2. Social and family well being * b3. Emotional well being * b4. Functional well being * b5. Additional concerns.
Quality of life -Symptom InventoryUp to 24 monthsAssessed using c. M. D. Anderson Symptom Inventory (MDASI). MDASI is a multi-symptom patient-reported outcome (PRO) measure for clinical and research use. Use the MDASI to assess the severity of symptoms experienced by patients with cancer and the interference with daily living caused by these symptoms. The following parameters will be reported: * c1a. Pain * c1b. Fatigue * c1c. Nausea * c1d. Disturbed sleep * c1e. Distress/feeling upset * c1f. Shortness of breath * c1g. Difficulty remembering * c1h. Lack of appetite * c1i. Drowsiness * c1j.

Enjoyment of life * c1s. Mood A total of eight quality of life parameters will be reported on each pediatric transplant patient. * c2a.Pain and Hurt * c2b. Fatigue and Sleep * c2c. Nausea * c2d. Worry * c2e. Nutrition * c2f. Thinking * c2g. Communication
