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.
To examine efficacy and safety after 12-week administration of ASP7991 in secondary hyperparathyroidism patients undergoing hemodialysis
The purpose of the study is to assess viral kinetics and clinical symptoms kinetics of Respiratory Syncytial Virus (RSV) in pediatric patients hospitalized with RSV confirmed lower respiratory tract infection (LRTI).
The purpose of the COAST clinical study data will be to utilize and to gain approval for commercializing the Micro Crown as part of the Coronary Orbital Atherectomy System (OAS).
The investigators assessed the hypothesis that whether RH-PAT index (RHI) as a marker of endothelial dysfunction could predict occurrence of ISR after percutaneous coronary intervention (PCI).
The study is performed to assess the efficacy and safety of different doses of BAY1002670 in subjects with uterine fibroids. The dose-response relationship will be evaluated. Further, the study aims to establish a population pharmacokinetic/pharmacodynamic relationship for BAY1002670 in subjects with uterine fibroids. To assess the efficacy of BAY1002670 the interchangeability of menstrual pictogram and alkaline hematin method for the judgement of menstrual blood loss will be assessed.
The purpose of this study is to evaluate the mean gain in best corrected visual acuity and the number of intravitreal ranibizumab (IVR) injections under the combination treatment of IVR, focal/grid laser and panretinal photocoagulation. Our hypothesis is that suitable photocoagulation decreases the number of IVR injections.
In Japan, post-approval execution of post marketing surveillance (PMS) is requested by the Japanese Pharmaceutical Affairs Law (J-PAL) in order to accumulate safety and efficacy data for reexamination. Reexamination period is defined by J-PAL. Eight years after approval of a new substance, results of PMS need to be submitted as a part of reexamination dossier to the Japanese regulatory authority, the Ministry of Health, Labour and Welfare (MHLW).
Early recurrence of cardioembolic stroke in patients with atrial fibrillation is common, reaching approximately 6% within 30 days after initial stroke. Therefore, it is preferable to provide early anticoagulation for cardioembolic stroke. However, early anticoagulation may increase the risk of hemorrhagic transformation of cerebral infarcts. It is difficult to decide the timing of initiation for anticoagulant therapy in stroke patients with non-valvular atrial fibrillation (NVAF). In 2013 the European Heart Rhythm Association presented the practical guides for oral anticoagulants in NVAF patients, which recommend that the optimal time to start anticoagulant therapy should be determined according to the stroke severity. However, this recommendation is principally an experts' opinion and is not suitable in the clinical practice in Japan. RELAXED, a multicenter observational study is planned to evaluate the efficacy and safety of an oral direct activated coagulation factor Xa inhibitor, rivaroxaban, for acute ischemic stroke patients with NVAF in consideration of the infarct size, timing of initiation for rivaroxaban medication, and other patient characteristics, and thereby to determine the optimal timing of the initiation during acute ischemic stroke. The consecutive acute ischemic stroke / transient ischemic attack (TIA) patients with NVAF who are treated with rivaroxaban will be enrolled. The infarction size at 0-48 hours after stroke onset will be measured by the diffusion weighted image (DWI) MRI. The primary efficacy endpoint is recurrent ischemic stroke within 3 months. The primary safety endpoint is major bleedings within 3 months. The optimal timing to initiate rivaroxaban during acute ischemic stroke is determined by analysis of co-relation between primary endpoints and the infarct size / time to initiate rivaroxaban.
To investigate the steady state pharmacokinetics of different formulation of Telmisartan, Amlodipine, and Hydrochlorothiazide (HCTZ).
The primary purpose of this study is to evaluate the safety and tolerability of intravenous (IV) ALXN1007 in persistently antiphospholipid (aPL)-positive patients with at least 1 of the following non-criteria manifestations of APS: aPL-nephropathy, skin ulcers and/or thrombocytopenia.
