NCT00484159
Lumbar zygapophysial (facet) joint pain is a common cause of low back pain. Radiofrequency (RF) denervation is an effective and low risk treatment of chronic low back pain of suspected facet joint etiology. Blocks of the medial branches innervating the joints are commonly used to localize the pain and make the diagnosis of facet joint pain. There is currently no standard number of diagnostic blocks: zero, one, and two blocks have all been utilized. Considering the high false positive and false negative rates of these blocks, the cost: benefit ratio has been questioned. No study to date has examined the practice of diagnostic medial branch blocks before RF denervation. The purpose of this study is to determine the optimal number of blocks before radiofrequency denervation. Three groups of patients will be studied. In group I, patients will undergo RF denervation based on history and physical exam alone. In group II, patients will undergo RF denervation based on a positive response to a single diagnostic block with local anesthetic. In group III, patients will undergo RF treatment only after a positive screening block and a positive confirmatory block.
NCT00077883
The purpose of this trial is to study the efficacy and safety of the combination of TLK286 with cisplatin as first-line therapy for patients with locally advanced or metastatic non-small cell lung cancer.
NCT00057720
The purpose of this study is to demonstrate superiority in survival in favor of TLK286 as compared to active control therapy with Doxil/Caelyx or Hycamtin in the intent-to-treat (ITT) populations.
NCT00040677
ICA-17043 is being developed for the chronic treatment of patients with sickle cell disease (SCD) in both adults and children. ICA-17043 is a potent and specific inhibitor of a channel in human red blood cells (RBCs) that blocks RBC dehydration. ICA-17043 is expected to inhibit RBC dehydration and thus should prevent or delay the sickling process. By reducing sickled cells, an improvement in anemia, a reduction in painful crises, and ultimately, less end-organ disease is anticipated.
NCT00001934
This study will examine the safety and effectiveness of Zenapax (a laboratory-manufactured antibody) in treating multiple sclerosis. Multiple sclerosis may be caused by an abnormal immune response in which white blood cells called T lymphocytes attack the myelin sheath that covers nerves and parts of the spinal cord. Zenapax binds to protein receptors on lymphocytes, keeping them from interacting with interleukin-2, a substance necessary for their growth. Patients with multiple sclerosis who have had at least one relapse within 18 months of the start of the study and in whom interferon-beta treatment has not been successful may be considered for this study. There are two study phases: baseline and treatment. During the baseline phase, patients will have three magnetic resonance imaging (MRI) scans over 2 months to evaluate their disease activity. During treatment, patients will receive seven intravenous (I.V.) infusions of Zenapax in the clinic. The first two infusions will be given 2 weeks apart; the next five will be given once a month. Patients will have MRI scans before each infusion. The MRIs will be done using the standard procedure and again using a contrast agent, gadolinium, injected into a vein. Gadolinium helps identify new multiple sclerosis lesions in the brain. Blood and urine samples will be taken during each clinic visit. In addition, patients will have skin tests, similar to a tuberculin test, to evaluate immune status, and will be asked to undergo two lumbar punctures (spinal tap; these will be optional)-one before the treatment phase begins, and another when treatment is completed. Lymphocytes will also be collected from patients before, during and after treatment. The lymphocytes are obtained by a procedure called apheresis: about a pint of whole blood is drawn through a needle in the arm, the lymphocytes are separated out and removed by a machine, and the rest of the blood is returned through a needle in the other arm. These studies will hopefully allow conclusions about the safety of Zenapax in MS, but also address its effectiveness with respect to modifying the inflammatory activity in the brain of MS patients and inhibit autoimmune T lymphocytes that are involved in the disease process. ...
NCT01152229
The objective is to describe and quantify levels of platelet reactivity in three different cohorts of patients taking thienopyridine: patients who report nuisance bleeding, patients who report alarming bleeding, and patients who report no nuisance or alarming bleeding. The investigators hypothesize that patients with nuisance or alarming bleeding events on maintenance thienopyridine therapy will have lower levels of platelet reactivity than patients without nuisance or alarming bleeding on thienopyridine therapy.
NCT00525850
To evaluate two different diets and their effects on weight loss and measurements of several risk factors for cardiovascular disease. One diet will be a high saturated fat diet (HSFD) and the other is a low saturated fat diet (LSFD) that limits fat but especially saturated fat as red meat. All participants in this study must eat both diets as this is a randomized cross-over design.
NCT00243503
The current study is to evaluate: Overall response rate for the combination of trastuzumab and SU011248 in metastatic or locally recurrent breast cancer; evaluate safety and tolerability of the combination; measure duration of tumor control and survival; assess patient reported outcomes; assess PK in combination with trastuzumab and compare efficacy and safety.
NCT00509301
RATIONALE: Cotara® is an experimental new treatment that links a radioactive isotope (iodine 131) to a targeted monoclonal antibody. This monoclonal antibody is designed to bind tumor cells and deliver radiation directly to the center of the tumor mass while minimizing effects on normal tissues. Cotara® thus literally destroys the tumor "from the inside out." This may be an effective treatment for glioblastoma multiforme, a malignant type of brain cancer. PURPOSE: This trial is studying the safety and radiation distribution of Cotara® in patients with recurrent glioblastoma multiforme.

NCT00143715
Excessive prolongation of the international normalized ratio (INR) occurs frequently in patients taking warfarin; in fact, about one in six INR values is above the desired range. Excessive prolongation of the INR is clinically important because the risk of bleeding approximately doubles for each one point increase in the INR beyond the usual therapeutic range. Thus, treatment strategies which rapidly and reliably lower an excessively prolonged INR into the desired range have the potential to reduce bleeding. When taken by patients with INR values between 4.5 and 10, a small dose of oral vitamin K (1 mg to 2.5mg) reduces the INR into the desired INR range in about 75% of cases within 24 hours of its administration. If warfarin is simply withheld, and no vitamin K is given, about 25% of patients will have an INR in the desired range at 24 hours. However, vitamin K is rarely given to such patients. In a recent survey carried out by our group, less than 20% of such patients would have been given low dose oral vitamin K by a group of physicians who regularly supervise warfarin therapy. The most common treatment for excessive prolongation of the INR is to simply withhold warfarin and allow the INR to fall into the therapeutic range. Although this strategy is effective its safety has never been adequately examined. In fact, recent evidence suggests that patients with INR values of more than 6.0 who are treated with simple warfarin withdrawal have a risk of major bleeding of 4% in the two weeks after they develop their prolonged INR. When asked why they did not give oral vitamin K to a non-bleeding patient who has an excessively prolonged INR, physicians generally give one of three reasons: (1)They are not convinced that oral vitamin K reduces bleeding. (2) They are concerned that oral vitamin K may cause thrombosis. (3) In contrast with simply withholding warfarin, giving oral vitamin K requires a patient to visit the physician, and the physician must have a supply of vitamin K. The investigators hypothesize that the routine practice of not administering oral vitamin K to patients with excessively prolonged INR values is causing patients to have major, life-threatening and fatal bleeds. To convince physicians that oral vitamin K should be administered to all non-bleeding patients with INR values of more than 4.5, the investigators propose a study which the investigators anticipate will demonstrate that oral vitamin K reduces bleeding, does not cause thrombosis, and can be administered at home without direct physician supervision. To accomplish these goals, the investigators propose a multinational, double-blind, placebo-controlled trial. The investigators will randomize patients with INR values between 4.5 and 10.0 to receive 1.25 mg of oral vitamin K or placebo and follow them for bleeding and thrombosis. Patients with INR values of more than 10.0 will receive a single 1.25 mg dose of oral vitamin K. Successful completion of this study will establish a treatment standard supported by clinical data which will, in turn, change the way that patients taking warfarin who present with an excessively prolonged INR are treated.
