Purpose
The main objective of this randomized trial is To compare disease-free survival (DFS) in high risk leukemia patients who underwent haploidentical HCT followed by an add back strategy of HSV-Tk donor lymphocytes or standard haploidentical HCT

- Disease-free survival (DFS) [ Time Frame: From the randomization date to relapse date or death ] [ Designated as safety issue: Yes ]
- Overall Survival (OS) [ Time Frame: From randomization to death ] [ Designated as safety issue: No ]
- Immuno reconstitution (IR) [ Time Frame: Weekly after HCT ] [ Designated as safety issue: Yes ]Defined as the time to reach a level of circulating CD3+ ≥ 100/µl for two consecutive observations
- Engraftment rate [ Time Frame: Weekly up to IR after HCT or up to 6 months after HCT if no IR ] [ Designated as safety issue: Yes ]Defined as the persistent blood cells count as a predefined level
- Cumulative incidence of grade 2, 3, or 4 acute GVHD (aGvHD) [ Time Frame: From the date of HCT until the date to the first occurence of relapse ] [ Designated as safety issue: Yes ]Diagnosed and graded according to standard criteria and computed in patients who will survive during the first 100 days after the transplantation.
- Cumulative incidence of extensive chronic GvHD (cGvHD) [ Time Frame: For at least 100 days after transplantation ] [ Designated as safety issue: Yes ]Diagnosed and graded according to standard NIH consensus criteria and computed in patients who will survive for at least 100 days after transplantation.
- Cumulative incidence of relapse (CIR) [ Time Frame: From the date of HCT until the date to the first occurence of relapse or death ] [ Designated as safety issue: Yes ]Defined on the basis of morphologic evidence of leukaemia in bone marrow or other sites.
- Disease-Free Survival (DFS) [ Time Frame: From the date of randomization until the date of relapse or death ] [ Designated as safety issue: No ]
- Incidence and duration of infectious episodes and infectious disease mortality [ Time Frame: From randomization to the end of study ] [ Designated as safety issue: Yes ]
- Evaluate the acute and long-term toxicity related to the HSV-Tk infusions [ Time Frame: From HSV-Tk infusions to death ] [ Designated as safety issue: Yes ]
- Quality of life (QoL) and Medical Care Utilization (MCU) in both arms [ Time Frame: From randomization to end of study ] [ Designated as safety issue: No ]Medical resource use data collected will be used in health economic analyses where it may be combined with other data from other sources such as cost data or other clinical parameters.
- Non-relapse mortality (NRM) [ Time Frame: From the date of HCT until to death ] [ Designated as safety issue: Yes ]Defined for all patients as any death without previous occurrence of a documented relapse

Detailed Description:
Delayed immune-reconstitution remains one of the main limitation of haploidentical stem cell transplantation. The risk of severe infections remains high for several months and CD4+ reconstitution could take more than 10 months. The low number of lymphocytes infused with the graft, the degree of HLA disparity, and a reduced thymic function in adults and differences in host/donor antigen presenting cells are contributing causes.
The infusions of HSV-TK engineered lymphocytes may represent a significant therapeutic improvement in haploidentical HCT, because it remarkably may enhance both GvL activity, thus reducing the occurrence of disease relapse, and post-transplant immune reconstitution in the absence of chronic immune suppression, thus decreasing the rate of both post-transplant opportunistic infections and transplant-related mortality. Furthermore, the efficient control of GvHD achieved via the suicide mechanism allows also the multiple infusion of HSV-TK-treated donor lymphocytes, when needed, that might further improve post-transplant host immune reconstitution, and survival in patients receiving haplo-HCT. Finally, this therapeutic approach can become a valuable option for all candidates, including patients with advanced disease and older age.
The proposed clinical trial represents an innovative therapeutic treatment for patients affected by high risk acute leukemia, who have undergone haploidentical stem cell transplantation.
