Study of KIR-Ligand Mismatched Haplo-Identical Natural Killer Cells Transfused Before Autologous Stem Cell Transplant

2014-08-27 03:54:10 | BioPortfolio

Summary

The purpose of this study is to induce anti-myeloma responses in patients with high risk or relapsed myeloma using combination chemo- and immunotherapy comprising sequentially: 1) lymphoid and myeloid suppressive conditioning, 2) adoptive transfer of purified KIR-ligand mismatched Natural Killer cells from a haplo-identical donor, and 3) autografting two weeks after infusion of NK cells to ensure autologous reconstitution. Other objectives include establishing the response rate, disease free survival, progression free survival and toxicity of regimen. Secondary objectives are to monitor the persistence of haplo-identical purified KIR-ligand mismatched Natural Killer cells by molecular methods, select haplo-identical purified KIR-ligand mismatched donors and predict prior to therapy which donor will induce a response, monitor Natural Killer cell reconstitution prior to and after autografting, and establish Natural Killer cell clones after autografting and determine origin and specificity.

Description

This study will induce anti-myeloma responses in patients with high risk or relapsed myeloma using combination chemo- and immunotherapy comprising sequentially: 1) lymphoid suppressive conditioning to avoid rejection of the donor NK cells, 2) adoptive transfer of purified KIR-ligand mismatched Natural Killer cells from a haplo-identical donor, and 3) autografting two weeks after infusion of NK cells to ensure autologous reconstitution.

Medical and Biotech [MESH] Definitions

An alkylating nitrogen mustard that is used as an antineoplastic in the form of the levo isomer - MELPHALAN, the racemic mixture - MERPHALAN, and the dextro isomer - MEDPHALAN; toxic to bone marrow, but little vesicant action; potential carcinogen.

An interleukin receptor subunit that was originally discovered as a component of the INTERLEUKIN 2 RECEPTOR. It was subsequently found to be a component of several other receptors including the INTERLEUKIN 4 RECEPTOR, the INTERLEUKIN 7 RECEPTOR, the INTERLEUKIN-9 RECEPTOR, the INTERLEUKIN-15 RECEPTOR, and the INTERLEUKIN-21 RECEPTOR. Mutations in the gene for the interleukin common gamma chain have been associated with X-LINKED COMBINED IMMUNODEFICIENCY DISEASES.

Cell surface receptors for INTERLEUKIN-13. Included under this heading are the INTERLEUKIN-13 RECEPTOR ALPHA2 which is a monomeric receptor and the INTERLEUKIN-4 RECEPTOR TYPE II which has specificity for both INTERLEUKIN-4 and INTERLEUKIN-13.

A cytokine subunit that is a component of both interleukin-12 and interleukin-23. It binds to the INTERLEUKIN-12 SUBUNIT P35 via a disulfide bond to form interleukin-12 and to INTERLEUKIN-23 SUBUNIT P19 to form interleukin-23.

Precursor of an alkylating nitrogen mustard antineoplastic and immunosuppressive agent that must be activated in the LIVER to form the active aldophosphamide. It has been used in the treatment of LYMPHOMA and LEUKEMIA. Its side effect, ALOPECIA, has been used for defleecing sheep. Cyclophosphamide may also cause sterility, birth defects, mutations, and cancer.
