This is a single center phase II trial designed to expand CD3/CD19 depleted allogeneic natural killer (NK) cells and induce disease response in patients with recurrent ovarian, fallopian tube, primary peritoneal cancer and advanced metastatic breast cancer using chemotherapy followed by haploidentical NK cells and IL-2.
The study will use a two-step enrollment procedure. Enrollment in stage I will include patients with an early stop if 3 or fewer patients have successful NK expansion. If 4 or more have expansion, enrollment will continue.
Allocation: Non-Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment

RATIONALE: Giving chemotherapy before a donor natural killer (NK) cell infusion helps stop the growth of tumor cells. It also helps stop the patient's immune system from rejecting the dono...
RATIONALE: Drugs used in chemotherapy, such as cyclophosphamide and fludarabine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them f...
RATIONALE: Aldesleukin may stimulate natural killer cells to kill cancer cells. Treating natural killer cells with aldesleukin in the laboratory may help the natural killer cells kill more...
Primary: Evaluate safety, feasibility, persistence, and anti-tumor effect of infused haploidentical donor-derived natural killer (NK) cells and low-dose interleukin-2 (IL-2). Secon...
This is a phase II therapeutic study of related donor HLA-haploidentical NK-cell based therapy after a high dose of fludarabine/cyclophosphamide with denileukin diftitox preparative regime...
Natural killer (NK) cells eliminate cancer cells in a contact-dependent manner. However, how NK cells find cancer cells remain unclear. Here, using time-lapse imaging, we investigated how individual N...
Natural killer (NK) cell interactions with stimulatory dendritic cells (SDC) enhance immunotherapy.
The natural killer group 2D (NKG2D) receptor on natural killer (NK) cells play an important role in immunosurveillance to cancer cells, which could mediate the eradication of tumor cells through speci...
In our previous study, we demonstrated that sesamolin can increase the level of cancer cell susceptibility to natural killer (NK) cell mediated cytolysis when it treats cancer cells. The present study...
Natural killer (NK) cells are key players of the innate immune system. NK cells provide protection against infectious pathogens and malignancies in cell. This characteristic may be attributable to the...
Bone marrow-derived lymphocytes that possess cytotoxic properties, classically directed against transformed and virus-infected cells. Unlike T CELLS; and B CELLS; NK CELLS are not antigen specific. The cytotoxicity of natural killer cells is determined by the collective signaling of an array of inhibitory and stimulatory CELL SURFACE RECEPTORS. A subset of T-LYMPHOCYTES referred to as NATURAL KILLER T CELLS shares some of the properties of this cell type.
Cytolytic lymphocytes with the unique capacity of killing natural killer (NK)-resistant fresh tumor cells. They are INTERLEUKIN-2-activated NK cells that have no MAJOR HISTOCOMPATIBILITY COMPLEX restriction or need for antigen stimulation. LAK cells are used for ADOPTIVE IMMUNOTHERAPY in cancer patients.
A specialized subset of T-LYMPHOCYTES that exhibit features of INNATE IMMUNITY similar to that of NATURAL KILLER CELLS. They are reactive to glycolipids presented in the context of the major histocompatibility complex (MHC) class I-like molecule, CD1D ANTIGEN.
Receptors that are specifically found on the surface of NATURAL KILLER CELLS. They play an important role in regulating the cellular component of INNATE IMMUNITY.
Immunized T-lymphocytes which can directly destroy appropriate target cells. These cytotoxic lymphocytes may be generated in vitro in mixed lymphocyte cultures (MLC), in vivo during a graft-versus-host (GVH) reaction, or after immunization with an allograft, tumor cell or virally transformed or chemically modified target cell. The lytic phenomenon is sometimes referred to as cell-mediated lympholysis (CML). These CD8-positive cells are distinct from NATURAL KILLER CELLS and NATURAL KILLER T-CELLS. There are two effector phenotypes: TC1 and TC2.
In a clinical trial or interventional study, participants receive specific interventions according to the research plan or protocol created by the investigators. These interventions may be medical products, such as drugs or devices; procedures; or change...
