There are about 7997 clinical studies being (or have been) conducted in Japan. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The purpose of the study is to compare how treatment with Fulvestrant (FASLODEX) or Anastrozole (ARIMIDEX) effects disease progression for women with locally advanced or metastatic breast cancer who have not had prior hormonal treatment.
The investigators identified three cancer-testis antigens, as targets for cancer vaccination against lung cancer. In this clinical study, the investigators examine using a combination of three peptides from these three antigens (S-488410) the safety, immunogenicity, and antitumor effect of vaccine treatment for advanced non-small cell lung cancer patients.
International GBS Outcome Study (IGOS) is a study conducted by the members of the Inflammatory Neuropathy Consortium (INC) and Peripheral Nerve Society (PNS) on disease course and outcome in Guillain-Barré syndrome (GBS). The IGOS aims to identify clinical and biological determinants and predictors of disease course and outcome in individual patients with Guillain-Barré syndrome, as early as possible after onset of disease.
The purpose of this study is to determine choice of anticoagulant therapy during acute and chronic stages of ischemic stroke/TIA and short- and long-term outcomes, including stroke recurrence and bleeding complications, in patients having nonvalvular atrial fibrillation.
The primary objective of this study is to make a comparison of safety and efficacy of DESs with different link number (2-link Nobori and 3-link Xience) in patients with de novo true bifurcation lesions. The minimum lumen diameter of the side branch ostium in bifurcation at 8 months and the MACE rate until one year after PCI will be assessed in both groups.
It is well known that incretin, particular GLP-１enhances satiety and reduces energy intake in controlling appetite and dietary in humans (Flint A, et al. Gutzwiller JP et al.). Recently, incretin-based therapy has been attracted a lot of interest (Hare KJ, Knop FK). However, it is not clear how the incretin-based therapy affects energy and content of dietary intake in patients with type 2 diabetes mellitus (T2DM). Previously, the investigators reported the amount of energy and content of dietary intake in type 2 diabetic Japanese patients with more than 10 years of long time duration after discovery using questionnaire (Inoue K et al.) and the patients were impaired a secretion of active GLP-1 (Kamoi et al). The investigators examine whether the incretin-based therapy effects on the energy and content of dietary intake in the same patients before and one year after administration of incretin-related drugs using the same method previously (Inoue K et al.).
Previous cross-sectional studies have demonstrated that blood pressure (BP) measurements at home (HBP) in the morning offer stronger predictive power for micro- and macrovascular complications in patients with type 1 and 2 diabetes than casual/clinic blood pressure measurements (CBP) (Kamoi K et al, 2002-2003). Further, a prospective, longitudinal study for 6 years in patients with type 2 diabetes also demonstrated that control of wakening-up HBP provides the stronger predictive power for the outcomes than that of CBP did (Kamoi et al, 2010). However, it is not clear to show which of BP measurement provides the stronger predictive power for outcomes by comparing cumulative events over a longer time than 6 years. Therefore, the investigators examined which of HBP or CBP provides the stronger predictive power for outcomes in addition of renal anemia reported previously over 10 years in the patients with type 2 diabetes.
Rossi NF & Schrier RW reported that for having differential diagnosis in hyponatremic state, it is important to have a grasp of extra cellular fluid (ECF) volume. However, recent works showed that it is not easy to estimate the ECF state using by physical findings and by usual laboratory methods. Damaraju SC et al. first demonstrated that measuring central venous pressure (CVP) is significant to evaluate the ECF state in hyponatremic patients with intracranial diseases. Accordingly, it may be useful to measure the CVP in the hyponatremic patients. However, usually it is difficult to measure the CVP in all patients with hyponatremia because that the method is due to invasive procedure. With recently development, it is possible to estimate the CVP calculation using cardiac echogram without invasion. However, it is not clear that an evaluation by using such echogram estimates the state of ECF volume in hyponatremic patients. Therefore, the investigators examine whether the CVP calculation by using cardiac echogram by Marcelino P et al. method without invasion is estimated such condition in hyponatremic patients before and after treatments. As the primary endpoint, the VCI index values is investigated and compared with each group before and after correction of disorders of fluid with sodium. Furthermore, some variables including sodium, potassium, chloride, creatinine, BUN, uric acid, osmolality in blood and urine and plasma vasopressin are investigated and compared with each group before and after correction of disorders of fluid with sodium.
The aim of this study is to clarify safety of robot assisted distal gastrectomy with lymph node dissection in patients with stage Ia early gastric cancer.
The clinical benefits of sunitinib and sorafenib have been demonstrated in patients with cytokine-refractory metastatic renal cell carcinoma. Sunitinib has also been shown to improve progression free survival and overall survival in a comparative study with interferon-alpha. When sunitinib is used as first-line molecular-targeted therapy, switching to sorafenib is one of the treatment options after disease progression. Reversely, when sorafenib is used as first-line molecular-targeted therapy, sunitinib is used as second-line therapy. The goal of cancer treatment is cure, and if cure is not possible, it is to prolong survival. In this study, sunitinib or sorafenib will be administered as first-line molecular-targeted therapy and treatment switched to the other test drug, sorafenib or sunitinib, when disease progression is detected to assess which treatment sequence produces longer progression free survival and offers a better safety profile (causing fewer adverse events). The purpose of this trial is to compare progression free survival of first line sunitinib versus sorafenib, and that of two treatment sequences, i.e. sunitinib followed by sorafenib versus sorafenib followed by sunitinib.
