NCT00607672
Each year over a million patients worldwide undergo cardiac surgery requiring cardiopulmonary bypass (CPB).1 CPB is associated with significant morbidity including hemodynamic instability, the transfusion of allogenic blood products, and inflammation. Blood product transfusion increases mortality after cardiac surgery. Enhanced fibrinolysis contributes to increased blood product transfusion requirements in the perioperative period. CPB activates the kallikrein-kinin system (KKS), leading to increased bradykinin concentrations. Bradykinin, acting through its B2 receptor, stimulates the release of nitric oxide, inflammatory cytokines and tissue-type plasminogen activator (t-PA). Based on data indicating that angiotensin-converting enzyme (ACE) inhibitors reduce mortality in patients with coronary artery disease, many patients undergoing CPB are taking ACE inhibitors. While interruption of the renin-angiotensin system (RAS) reduces inflammation in response to CPB, ACE inhibitors also potentiate the effects of bradykinin and may augment B2-mediated change in fibrinolytic balance and inflammation. In contrast, angiotensin II type 1 receptor antagonism does not potentiate bradykinin and does not inhibit bradykinin metabolism. Studies in animals suggest that bradykinin receptor antagonism inhibits reperfusion-induced increases in vascular permeability and neutrophil recruitment.A randomized, placebo controlled clinical trial of a bradykinin B2 receptor antagonist demonstrated some effect on survival in patients with systemic inflammatory response syndrome and gram-negative sepsis. In addition, we and others have shown bradykinin B2 receptor antagonism reduces vascular t-PA release during ACE inhibition. The current proposal derives from data from our laboratory and others elucidating the role of the KKS in the inflammatory, hypotensive and fibrinolytic response to CPB. Specifically, we have found that CPB activates the KKS and that ACE inhibition and smoking further increases bradykinin concentrations. During CPB, bradykinin concentrations correlate inversely with mean arterial pressure and directly with t-PA. Moreover, we have found that bradykinin receptor antagonism attenuates protamine-related hypotension following CPB. The current proposal tests the central hypothesis that the fibrinolytic and inflammatory response to cardiopulmonary bypass differ during angiotensin-converting enzyme inhibition and angiotensin II type 1 receptor antagonism.
NCT00387010
The primary purpose of the study is to evaluate the impact of treatment with fentanyl buccal tablets on the anxiety symptoms commonly associated with chronic pain in patients with breakthrough pain (BTP). Other purposes are to assess the management of BTP, to evaluate patient functioning, and to determine any influences on the successful dose achieved.
NCT00734591
In studies of Exubera in persons with diabetes, lung cancer occurred in a few more people who were taking Exubera than in people who were taking other diabetes medicines. All subjects diagnosed with lung cancer had a history of smoking and the number of lung cancer cases observed fell within the expected range based on population-based data. There is currently not enough information to determine if any of the observed lung cancer cases were related to Exubera use, therefore, the study is being conducted to further investigate whether Exubera use makes the appearance of lung cancer more likely.
NCT01013948
This is a cross-sectional study to determine the prevalence of symptomatic airway obstruction using the LFQ as a screening tool in primary care patients with a history of cigarette smoking and to provide descriptive data of this patient population. The study design is multicenter, cross-sectional, and involves a single visit. This study is not intended to evaluate the efficacy or safety of any investigational products. Following completion of written informed consent, eligible study subjects will complete a single study visit encompassing all required study assessments. Study subjects will not receive blinded study medication for evaluations of efficacy and safety. All eligible patients will complete a self-administered Web survey that will include the LFQ. To meet both the primary and secondary aims, all patients with LFQ ≤ 18 (current cut-off for obstruction), as well as 5% of patients who score \> 18, will be candidates for spirometric assessment. Only this subset of patients will undergo pulmonary function tests. Albuterol will be self-administered for determination of post-bronchodilator forced expiratory volume in one-second (FEV1)/forced vital capacity (FVC) ratio and post-bronchodilator FEV1 percentage of predicted normal. The study will end when 800 patients have been assessed spirometrically or 3,000 patients have completed the LFQ (whichever criterion is achieved first). Prior to implementation of the full study, a pilot study will be conducted at two of the chosen study sites to pretest the proposed study procedures.

NCT00889863
This two-part study assessed the sustained efficacy of canakinumab in the double-blind Part II and the ability to taper steroids in the open label Part I.
NCT00555321
The purpose of this clinical research study is to evaluate the effects of belatacept, relative to tacrolimus, on the incidence of rejection, graft loss and death in subjects receiving a liver transplant
NCT00456248
This is a 60-to-72 week multicenter study to evaluate Infergen and Ribavirin in patients with Chronic Hepatitis C Virus after partial response to treatment using peginterferon-alfa and Ribavirin therapy. The study will be conducted at approximately 50 sites across the United States.
NCT00226759
The anterior cruciate ligament (ACL) is an important stabilizer of the knee. Orthopedic surgeons replace the torn ligament during ACL reconstruction surgery. Surgical trauma initiates an acute inflammatory response, including swelling and pain, that leads to restricted joint motion and loss of function. OMS103HP was designed to deliver targeted therapeutic agents directly to the surgical site during the arthroscopic procedure to inhibit inflammation and pain before they can begin. The purpose of this study is to assess the effectiveness and safety of OMS103HP in improving knee function following ACL reconstruction. Secondary benefits being evaluated include reduced postoperative pain, improvement in knee range of motion and earlier return to work.
NCT00447187
This was a pivotal trial to determine whether LX201 reduces the likelihood of a graft rejection episode following corneal transplantation in patients at high immunological risk for rejection.
NCT00603304
The CAMUS trial will test Saw palmetto in about 369 men. Men who decide to be part of the CAMUS trial will be given one out of two possible treatments at random. One out of every two men would get an inactive placebo treatment. One out of every two men would get Saw palmetto pills. This kind of scientific study is the best way to find out if the plant extracts really work to prevent men with benign prostatic hyperplasia (BPH) from getting worse. During the study, men will not know which of the two treatments they are assigned to. They will be followed very closely by a study team every 12 weeks to see how they are doing. Men in the CAMUS trial will be studied over 72 weeks. Tests and all medications needed as part of the study will be provided at no charge to the participant. Participants will be responsible for all other costs not associated with the study tests and medications. All information on study participants will be held in the strictest confidence and no one would have access to patient information other than the required authorized health care and research personnel.

NCT00080678
RATIONALE: Drugs used in chemotherapy, such as docetaxel, work in different ways to stop tumor cells from dividing so they stop growing or die. Imatinib mesylate may stop the growth of tumor cells by blocking the enzymes necessary for their growth. Combining docetaxel with imatinib mesylate may be effective treatment for androgen-independent prostate cancer and bone metastases. PURPOSE: This randomized phase II trial is studying docetaxel and imatinib mesylate to see how well they work compared to docetaxel alone in treating patients with androgen-independent prostate cancer and bone metastases.
NCT00892723
