Eligibility

Age
18 Years to 99 Years

Inclusion criteria

Inclusion criteria: • Age >= 18 with HCT comorbidity index < 3 (Appendix I);• Any of the following conditions:;• AML and ALL in 1st complete remission (CR) at high risk of relapse based on negative prognostic factors (for the definition of high-risk of relapse see Appendix H);• AML and ALL in 2nd or subsequent CR;• secondary AML in CR;• Absence of timely and suitable fully HLA matched or one HLA locus mismatched family or unrelated donor and, at Investigator*s discretion, absence of other possible therapeutic alternatives;• Stable clinical conditions and life expectancy > 3 months;• PS ECOG < 2;• Serum creatinine < 1.5 x ULN;• Bilirubin < 1.5 x ULN; transaminases < 3 x ULN;• Left ventricular ejection fraction > 45%;• QTc interval < 450 ms;• DLCO > 50%;• Patients and donors, or independent witnesses must sign an informed consent indicating that they are aware this is a research study and have been told of its possible benefits and toxic side effects.

Exclusion criteria

Exclusion criteria: • Patients with life-threatening condition or complication other than their basic disease;• Contraindication to haploidentical HCT as defined by the Investigator;• Patients with active CNS disease;• Pregnant or lactation. Patients both males and females with reproductive potential (i.e. menopausal for less than 1 year and not surgically sterilized) must practice effective;contraceptive measures throughout the study. Women of childbearing potential must provide a negative pregnancy test (serum or urine) within 14 days prior to registration.

Design outcomes

Primary

MeasureTime frame
Primary efficacy parameter: - Disease-Free Survival (DSF) will be measured for all patients from the date of randomization until the date of relapse or death from any cause, whichever occurs first

Secondary

MeasureTime frame
Secondary efficacy parameters: - Overall Survival (OS) will be measured for all patients from the date of randomization until death from any cause - Non-relapse mortality (NRM) will be defined for all patients as any death without previous occurence of a documented relapse - Immune Reconstitution (IR) will be defined as the time to reach a level of circulating CD3+ >= 100/µl - Engraftment rate will be defined as the persistent blood cells count above a predefined level (ANC >= 1 x 109/L per 3 consecutive days with evidence of donor haematopoiesis; platelets >= 50 x 109/L, unsupported by transfusions, for 7 days) - Cummulative incidence of grade 2, 3 or 4 acute GvHD, diagnosed and graded according to standard criteria, will be computed from the transplantation - Cummulative incidence extensive chronic GvHD, diagnosed and graded according to standard criteria, will be computed from the transplantation - Cummulative incidence of relapse will be defined on the basis of morphologic evidence of leukaemia in bone marrow or other sites. Safety and tolerability parameters: - Adverse Events (AE) and laboratory abnormalities graded according tot the CTCAE v 4.02 - laboratory assessments (urinalisis, hematology, blood chemistry, immunophenotype, PCR-TK, RCR analysis), bone marrow asprirate - physical examination and vital signs - Serious Adverse Events (SAE) - Suspected Unexpected Serious Adverse Reactions (SUSARs) - Long term follow up Quality of life: FACT-BMT to summarize and evaluate patient convenience and satisfaction Pharmacoeconomics on medical care utilization. To summarize and evaluate treatment group differences.
