Brief Summary

Patients receiving haplo-SCT are at high-risk of relapse. Vγ9Vδ2 T cells exhibit is a well-known population able to exert cytotoxicity toward a large range of tumor in vitro or in vivo. Activating and expanding Vγ9Vδ2 T cells early after haplo-SCT by using a combination of Zoledronic acid and low-dose interleukine (IL) -2 may be of benefit for patients by reducing incidence of relapse. The optimal dose of IL-2 to use remains to be determined. This will be a Phase 1 3+3 escalation study. Three to 15 patients are planned. It will be proposed to Patients who refuse to participate to have samples collected until day +70 to study immune and gamma/delta T cells reconstitutions after haplo-transplant.

Outcome Measures

Primary Outcomes (1)

  • determine the maximum tolerated dose (MTD) of early administration of increasing doses of low-dose IL-2 in combination with a fixed dose of Zoledronic acid after haplo-SCT

    A dose-limiting toxicity (DLT) will be defined as: * non-hematological toxicity of grade 4, including grade 4 acute GVHD 4. * non-hematological toxicity of grade 3 non-reversible for \> 7 days or reappearance of the same grade 3 after reintroduction of IL2 in case of return to at least one grade 1. * an acute GVHD grade 2-3 for \> 7 days or reappearance of GVHD grade 2-3 acute GVHD after reintroduction of IL2 if at least grade 1 acute GVHD is restored. * a reappearance of a grade 3/4 IL2 allergic reaction after reintroduction of IL2 in the event of a return to at least grade 1 after the occurrence of an allergic reaction of grade 3/4 IL2 when of the administration. * grade 4 pancytopenia with hypocellular bone marrow (no disease detection) for \> 4 weeks after the last administration of IL2.

    28 days after the last injection of IL2

Secondary Outcomes (13)

  • Engraftment
