Haploidentical Stem Cell Transplantation and NK Cell Therapy in Patients With High-risk Solid Tumors

September 17, 2018 updated by: KiWoong Sung, Samsung Medical Center

Haploidentical Stem Cell Transplantation Followed by NK Cell Infusion in Patients With High-risk Solid Tumors Who Failed Autologous Stem Cell Transplantation

To evaluate feasibility and efficacy of haploidentical stem cell transplantation in patients with high-risk solid tumors who failed after tandem high-dose chemotherapy and autologous stem cell transplantation.

To evaluate feasibility and efficacy of NK cell infusion after haploidentical stem cell transplantation in patients with high-risk solid tumors who failed after tandem high-dose chemotherapy and autologous stem cell transplantation.

Detailed Description

HaploSCT following reduced-intensity conditioning (RIC) regimen will be performed in patients with high-risk solid tumors. Both parents will be evaluated for their KIR genotype and phenotype and the one with the greatest degree of KIR-L mismatch with the patient will be selected as the donor. In addition, ex-vivo expanded NK cells derived from the donor will then be administered after haploSCT to increase the GVT effect. Low-dose IL-2 will be given after expanded NK cell infusion to enhance NK cell alloreactivity.
