Therefore, we performed this study to investigate the role of haploidentical NK cell therapy in patients with refractory or relapsed malignant melanoma.', 'detailedDescription': 'Human NK cells recognize and kill transformed cells in a MHC-unrestricted fashion, suggesting the role of cancer immunotherapy. However, autologous NK cells showed the lack of significant clinical effects, because they are inhibited by self MHC class I molecules, based on the missing-self hypothesis. Contrarily, haploidentical NK cells with KIR-ligand incompatibility can mediate graft-versus-leukemia effect and protect patients with acute myelogenous leukemia (AML) from graft-versus-host disease. In addition, adoptive transfer of haploidentical NK cells following high-intensity conditioning induced complete remission (26%) in poor-prognosis AML patients. Thus, this study was designed to investigate the role of adoptive NK cell therapy in patients with refractory or relapsed malignant melanoma using CD3+ depleting CliniMACS® system.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '75 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Histologically confirmed metastatic or relapsed malignant melanoma\n* Patients who received prior chemotherapy or immunotherapy\n* Patients who have at least one haploidentical donor willing to donate\n* ECOG performance status 0 or 1\n* 18 - 75 years\n* At least one measurable disease according to the RECIST criteria\n* Patients with 45% or more left ventricular ejection fraction\n* Patients with 50% or more predicted DLCO\n* Adequate bone marrow function: absolute neutrophil count ≥ 1.5 x 109/L; platelet count ≥ 100 x 109/L; and hemoglobin ≥ 9 g/dL\n* Adequate liver function: total bilirubin ≤ 1.0 x upper limit of the normal range (ULN); AST/ALT ≤ 2.5 x ULN; and alkaline phosphatase ≤ 2.5 x ULN\n* Adequate renal function: serum creatinine ≤ 1.0 x ULN or creatinine clearance ≥ 60 mL/min/1.73m2\n* At least 3 months of expected survival\n* Patients who signed informed consent\n\nExclusion Criteria:\n\n* Patients who received other chemotherapeutic agents within 30 days prior to study enrollment\n* Patients who received adoptive cell therapy including hematopoietic stem cell transplantation\n* Patients infected with HIV, HBV, or HCV\n* Hypersensitivity to cyclophosphamide or interleukin-2\n* Patients who received organ transplantation\n* Patients who had arrhythmia or ischemic heart disease\n* Pregnant or lactating women\n* Patients with uncontrolled infection who did not respond to appropriate antimicrobial agents'}, 'identificationModule': {'nctId': 'NCT00846833', 'briefTitle': 'Haploidentical NK Cell Infusion in Malignant Melanoma', 'organization': {'class': 'OTHER', 'fullName': 'Seoul National University Hospital'}, 'officialTitle': 'Phase I/II Study of Haploidentical Natural Killer Cell Infusion in Patients With Refractory or Relapsed Malignant Melanoma', 'orgStudyIdInfo': {'id': 'H-0808-024-253'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Cyclophosphamide, high-dose interleukin-2, NK cell', 'interventionNames': ['Biological: Haploidentical NK cell']}], 'interventions': [{'name': 'Haploidentical NK cell', 'type': 'BIOLOGICAL', 'description': '1.
