Summary: this phase i trial studies the side effects of donor stem cell transplant in treating patients with high risk acute myeloid leukemia. giving low doses of chemotherapy before a donor peripheral blood stem cell transplant helps stop the growth of cancer cells. it may also stop the patient's immune system from rejecting the donor's stem cells when they do not exactly match the patient's blood. the donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect)

primary objectives: i. to assess the feasibility of cytarabine based chemotherapy and human leukocyte antigen (hla)-mismatched allogeneic cellular therapy (hmmact) in patients with high risk acute myeloid leukemia (aml), with feasibility measured by induction mortality (im) and complete response rate. secondary objectives: i. to obtain preliminary estimates of clinical outcome following cytarabine based chemotherapy and hmmact in patients with high risk aml, as measured by event free survival (efs) and overall survival (os). ii. to further evaluate the safety outcomes of induction and consolidation of cytarabine and hmmact in terms of serious infections (grade 4), time to recovery of absolute neutrophil counts and platelets and incidence of graft versus host disease (gvhd). iii. to further evaluate the feasibility of this approach in terms of identifying a suitable donor in this elderly population. iv. to compare in preliminary manner the clinical outcomes of cytarabine and hmmact in patients with high risk aml as measured by complete response rate (crr), event free survival (efs) and overall survival (os) by donor/recipient hla-c1 vs c2 pairs. v. to characterize in a preliminary manner, the numbers of suppressor regulatory t cells (tregs), t helper 17 cells (th17), and cytotoxic t cells during pre and post hmmact treatment, and with clinical outcomes in leukemia. outline: induction chemotherapy: patients receive mitoxantrone hydrochloride intravenously (iv) on days 1-3 and cytarabine iv on days 1-7. hmmact: patients receive filgrastim (g-csf) mobilized peripheral blood stem cells (g-pbsc) on day 9. after completion of study treatment, patients are followed up monthly for 3 years.

Eligibility criteria:

if a bone marrow aspirate and biopsy were obtained within 28 days prior to the first dose of remission induction therapy then these tests may be submitted for review at university of southern california (usc) and a repeat screening bone marrow does not need to be conducted; * cohort a: newly diagnosed aml, no prior cytotoxic chemotherapy * cohort b: newly diagnosed aml, failed to achieve complete remission (cr) with single standard induction chemo. * patient has at least one medically fit family member expected to be hla mismatched at 1-9/10; more commonly and preferred: 4-6/10 loci (parent, sibling, niece/nephew, etc but adult children preferred) * absolute neutrophil count (anc) \> 1500, unless due to direct bone marrow involvement of disease * platelets \> 75,000, unless due to direct bone marrow involvement of disease * hemoglobin \> 8.0 gm/dl, transfusion allowed * serum creatinine \< 2.0 x the upper limits of institutional normal (uln) * total bilirubin \< 1.5 x the upper limits of institutional normal * aspartate aminotransferase (ast)/alanine aminotransferase (alt )\< 2.5 x the upper limits of institutional normal (=\< 5 x uln for patients with liver involvement of leukemia) * cardiac left ventricular ejection fraction (lvef) \> 45% * eastern cooperative oncology group (ecog) performance status of 0, 1, or 2 * estimated survival of at least 3 months * patients must be able to understand and agree to sign an institutional review board (irb)-approved informed consent form * women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control) prior to study entry, for the duration of study, and for two months after study participation * donor: donor screening; all donors will meet the standard blood donor criteria established by the participating local blood center, american association of blood banks (aabb) * donor: donors will be selected from among the subject's relatives, adult children preferred * donor: infectious disease testing will be done per hemacare policy and aaab guidelines * donor: donor and intended recipient red cell type and compatibility will be determined * donor: donors will be pre-selected on the basis of hla haploidentity * donor: if patient is cytomegalovirus (cmv)-negative, donors who are cmv-negative will be preferred; cmv serology of the donor will be tested prior to the allogeneic cell donation; donations from cmv-positive donors to cmv-negative recipients will be given if no cmv negative donor is available, and cmv surveillance and pre-emptive treatment given exclusion criteria: * cohort a: patients who have received prior cytotoxic chemotherapy, such as anthracyclines and cytarabine not permitted; but prior treatment with demethylating agents (azacytidine or decitabine, lenalidomide, etc) allowed. * cohort b: patients who have received prior fludarabine, clorarabine or drugs known to target t cells not permitted; but prior standard induction with anthracylines and cytarabine allowed including after demethylating agents. * have uncontrolled systemic infections, coagulation disorders, or other major medical illnesses of the cardiovascular or respiratory systems * pregnant and/or lactating * patients who have had non-biopsy surgery in the last 10 days * active central nervous system (cns) disease;
