Natural Killer Cells and Bortezomib to Treat Cancer
NCT00720785 · View on ClinicalTrials.gov ↗
Study Summary
Natural killer (NK) cells are white blood cells that have a limited ability to kill cancer cells. This ability might be enhanced if they are given 24 hours after an injection of the drug bortezomib. This study will determine the following: * What dose of NK cells can be given safely to subjects with metastatic solid tumors or leukemia. * The effectiveness and side effects of NK cell therapy * How the body handles NK cells. People between 18 and 70 years of age who have a solid tumor or leukemia, and for whom standard treatments are not effective, may be eligible for this study. Participants undergo the following procedures: Apheresis to collect NK cells. For this procedure, a catheter (plastic tube) is placed in a vein in the subject s arm. Blood flows from the vein into a cell separator machine, which separates the white cells from the other blood components. The white cells are extracted and the rest of the blood is returned to the body through a second tube placed in a vein in the other arm. Chemotherapy with the drug pentostatin to suppress the immune system and prevent it from attacking the NK cells that will be infused. Chemotherapy with bortezomib to increase NK cell function. Infusion of the NK cells. In this dose-escalating study, successive groups of patients entering the study receive increasingly higher numbers of cells to determine the highest safe dose level. Up to ten dose levels may be studied. Interleukin-2 drug therapy to maintain NK cell activity. Evaluations during therapy including: * Clinical assessment, history and review of medications * Blood draws for routine and research tests. * Pharmacokinetics study after the NK infusion to see how the body handles the cells. For this test, the number of NK cells in the blood are measured over time. This requires drawing about 1 teaspoon of blood at 15 minutes, 30 minutes, 1, 2, 4, 8, 12, and 24 hours after the infusion (day 1); then every 24 hours on days 2 through 7, then once on days 10, 14,

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00720785
The ClinicalTrials.gov registry entry for NCT00720785 describes a study currently listed as completed. It is categorized as Phase 1, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 35 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Heart, Lung, and Blood Institute (NHLBI), which has 381 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 5 conditions, with Multiple Myeloma appearing as the primary indexed condition, and to 2 interventions — of which Bortezomib is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT00720785 reports 1 study location spanning 1 distinct geographic area — top geographies include Maryland. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
