Purpose
Hematopoietic stem cell transplantation (HSCT) is one of the best, and sometimes the only, option for the treatment of leukemia. However, relapse rate was still the key question to influence the overall survival after transplantation, even in standard risk leukemia.There were good evidences that natural killer cells and T regulatory cells, which were expanded and stimulated by the application of IL-2, could mediate protection against GvHD while maintaining graft anti-tumor activity as a positive side effect. Meanwhile, it was found in our previous pilot study that low-dose IL-2 subcutaneous administration from 100 days for a prolonged period could be a safe and effective strategy to prevent relapse in acute lymphoblastic malignancy patients with high risk of recurrence after unmanipulated allo-HSCT.
The study hypothesis:
Prevention of relapse using low dose IL-2 following hematopoietic stem cell transplantation in patients with standard risk acute leukemia can
- reduce relapse rate
- improve survival

- To determine the feasibility and efficiency of administering 6 courses of subcutaneous IL-2 in these patients population. [ Time Frame: 2 years ] [ Designated as safety issue: Yes ]
investigate the incidences of severe GVHD and pancytopenia after IL-2 application to evaluate the safety of this drug.
observe the drug toxicity based on common toxicity criteria (CTC,version 3.0). compare the relapse rate and incidence of positive MRD between two groups to evaluate the efficiency of IL-2 application.
- To assess the immunologic impact of ultra-low dose subcutaneous IL-2 in patients after transplantation [ Time Frame: 2 years ] [ Designated as safety issue: No ]examine the immune reconstitution of subgroups of T cells after IL-2 application and compare with that of controlled group of patients.

Experimental: Interleukin-2
Interleukin-2 post-transplantation to prevent relapse of standard risk leukemia
|
Drug: Interleukin-2
Patients receive low dose interleukin-2(Daily 1×106 IU per square meter of body-surface area) on days 60 after unmanipulated blood and marrow transplantation. Interleukin-2 treatment repeats every 14 days for 6 courses in the absence of disease progression or unacceptable toxicity.
Other Name: IL-2

No Intervention: controlled group
controlled standard risk leukemia received regular transplantation without IL-2 intervention

Detailed Description:
Standard risk patients over 15 years old(except Ph+ ALL, AML t(8;21) and T-ALL) undergone unmanipulated blood and marrow transplantation following day 60 post-transplantation were randomized into treated group (with low dose IL-2 treatment) or controlled group (without any intervention post-transplantation). The end points were safety and clinical and immunologic response.Following time is 24 months.
Primary Outcome Measures:
*To determine the feasibility and efficacy of administering an 6 course of subcutaneous IL-2 in this patient population. [ Time Frame: 2 years ]
Secondary Outcome Measures:
*To assess the immunologic impact of ultra-low dose subcutaneous IL-2 in patients after transplantation [ Time Frame: 2 years ] Estimated Enrollment:360 Study Start Date:Jan 2012 Estimated Study Completion Date:Jan 2016
Intervention Details Description:
*Drug: Interleukin-2 Dose will vary depending upon when participant enters the trial: Given as a daily injection under the skin for 8 weeks.
Detailed Description:
- Patients receive low dose interleukin-2(Daily 1×106 IU per square meter of body-surface area) on days 60 after unmanipulated blood and marrow transplantation. Interleukin-2 treatment repeats every 14 days for 6 courses in the absence of disease progression or unacceptable toxicity.
- Participants will be seen periodically while they are receiving IL-2. Physical exams and blood tests will be performed weekly for the first two weeks and then every other week until the completion of 6 course therapy.
