Acute Myeloid Leukemia Clinical Trial
Total Marrow and Lymphoid Irradiation and Chemotherapy Before DSCT in Treating Patients With High-Risk ALL or AML
This phase II trial studies the safety and efficacy of total marrow and lymphoid irradiation (TMLI) in combination with two chemotherapy drugs, etoposide and cyclophosphamide, as a preparative regimen before donor stem cell transplant in treating patients with high-risk acute lymphocytic leukemia (ALL) or acute myeloid leukemia (AML) who have failed previous therapy. Intensity-modulated radiation therapy (IMRT) uses imaging to provide a three-dimensional view of the area to be irradiated. Doctors can then shape and direct the radiation beams at the area from multiple directions while avoiding, as much as possible, nearby organs. TMLI is a method of using IMRT to direct radiation to the bone marrow. Radiation therapy is given before transplant to suppress the immune system, prevent rejection of the transplanted cells, and wipe out any remaining cancer cells. TMLI may allow a greater radiation dose to be delivered to the bone marrow as a preparative regimen before transplant while causing fewer side effects than standard radiation therapy.
PRIMARY OBJECTIVES: I. Following a patient safety lead-in, evaluate the anti-tumor activity of the allogeneic hematopoietic cell transplant (alloHCT) preparative regimen - TMLI, cyclophosphamide (Cy) and etoposide (VP-16), as assessed by 2-year progression-free survival (PFS).
SECONDARY OBJECTIVES: I. Estimate overall survival (OS), cumulative incidence (CI) of relapse/progression, and non-relapse mortality (NRM) at 100 days, 1 year and 2 years.
II. Evaluate early and late toxicities/complications by organ and severity, and characterize by organ dose/dose volume, including acute/chronic graft-versus-host-disease (GVHD), infection, and longer-term complications (via protocol #s 07173 and 00029).
OUTLINE: Patients undergo image guided TMLI on days -9 to -5, receive etoposide intravenously (IV) on day -4 and cyclophosphamide IV on day -2, and undergo allogeneic peripheral blood stem cell or bone marrow transplant on day 0.
After completion of study treatment, patients are followed up for 5 years.
Participant has the ability and the willingness to sign the informed consent document (for adults only, for participants with mild cognitive abilities may use a legally authorized representative)
Documented (signed) informed consent; the patient, family member and transplant staff physician (physician, nurse, and social worker) meet at least once prior to starting the transplant procedure; during this meeting all pertinent information with respect to risks and benefits to donor and recipient will be presented; alternative treatment modalities will be discussed; the risks are explained in detail in the enclosed consent forms
Karnofsky performance status >= 70% =< 2
Acute lymphocytic leukemia or acute myelogenous leukemia who are not in first remission or second remission i.e. after failing induction therapy, or in relapse or beyond second remission; (prior therapy with VP-16 and Cytoxan is allowed)
All candidates for this study must have a human leukocyte antigen (HLA) (A, B, C, DR) identical siblings who is willing to donate bone marrow or primed blood stem cells or a 10/10 allele matched unrelated donor; a single allele mismatch at A, B, C, DR or DQ and a killer immunoglobulin-like receptor (KIR) mismatch at C will be allowed; all ABO blood group combinations of the donor/recipient are acceptable
The time from the end last induction, re-induction, or consolidation regimen should be greater than or equal to 14 days from planned start of study treatment; Note: Chemotherapy given within 14 days of planned study enrollment for the purpose of controlling counts is permitted

Serum glutamic oxaloacetic transaminase (SGOT) and serum glutamate pyruvate transaminase (SGPT) =< 5 x ULN
Measured creatinine clearance >= 80 ml/min per 24 hour urine collection OR serum creatinine =< 1.3 mg/dL
Women of child bearing potential only: Negative urine or serum pregnancy test
Pulmonary function tests: Forced expiratory volume in one second (FEV1) and carbon monoxide diffusion capacity (DLCO) (adjusted for Hb) >= 50% adjusted of predicted normal value
Echocardiogram (ECHO) or multi gated acquisition scan (MUGA): ejection fraction of >= 50% AND no finding of abnormal wall motion (i.e. report does not indicate that wall motion is "abnormal" or "altered")
Electrocardiogram (EKG) showing no ischemic changes and no abnormal rhythm
Agreement of men AND women-of-child-bearing-potential to use adequate contraception (hormonal or barrier method of birth control or abstinence) prior to study entry and for six months following duration of study participation; should a woman become pregnant or suspect that she is pregnant while participating on the trial, she should inform her treating physician immediately
DONOR ELIGIBILITY: Donor evaluation and eligibility will be assessed as per current City of Hope standard operating procedure (SOP)
Prior autologous or allogeneic hematopoietic stem cell
Prior radiation therapy that would exclude the use of TMLI
Plans during the trial to receive any other (non-trial) investigational agents, or concurrent biological, chemotherapy, or radiation therapy; (chemotherapy for white blood count control is permitted)
Uncontrolled illness including ongoing or active infection
History of allergic reactions attributed to compounds of similar chemical or biologic composition to etoposide
Patients with other active malignancies are ineligible for this study, other than localized malignancies
Patients with psychological or medical condition that patient's physician deems unacceptable to proceed to allogeneic hematopoietic stem cell transplantation
Women who are planning to become pregnant or breast feed during the trial
Subjects, who in the opinion of the investigator, may not be able to comply with the safety monitoring requirements of the study
