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 reproduce anatomical reduction and appropriate implant placement/choices during osteosynthesis for elbow fractures, a 3D preoperative planning system was developed. To assess the utility of 3D digital preoperative planning for the osteosynthesis of distal humerus fractures, the reproducibility of implant reduction shapes and placements in patients with distal humerus fractures will be evaluated.
Japanese Lead Extraction (J-LEX) Registry is an observational nationwide registry, performed by Japanese Heart Rhythm Society, collaborated with the National Cerebral and Cardiovascular Center. The acute success rate at discharge and the complications associated with transvenous lead extraction will be collected. J-LEX registry will provide a reliable information on indications, methods, the success rate, complications and the prognosis at 30 days prognosis.
Rheumatoid Arthritis (RA) is a chronic inflammatory disease causing pain, stiffness, swelling and loss of joint function. RA can reduce the ability to perform everyday tasks. The purpose of this study is to observe the incidence of serious infections, regardless of their relationship to RINVOQ, in Japanese daily practice. RINVOQ is an approved drug for the treatment of adults with moderately to severely active RA. This study evaluates medical records from institutions participating in the study to identify any adverse events (untoward medical occurrence), and reasons for discontinuation of RINVOQ in participants taking the study drug. A target of 1000 Japanese participants' data will be observed for 3 years. Participants will receive RINVOQ per their physicians' usual prescription. Individual data will be collected for three years. No additional study-related tests will be conducted during routine clinic visits. Only data which are routinely collected during clinic visits will be utilized for this study.
This study is conducted to investigate whether modified chemoradiotherapy with elective nodal irradiation reduces the locoregional recurrence that cannot be completely resected by salvage endoscopic resection and preserve esophagus without compromising overall survival.
Approximately one fourth of cases of endometrial cancer (EC) are diagnosed in premenopausal women, of whom approximately 40% wish to preserve their fertility. When arising in young women, EC usually presents with favorable prognostic features, as a focal, well differentiated endometrioid tumor, with minimal or absent myometrial invasion. This profile corresponds to the Type 1 EC, which correlates with the estrogen/progesterone receptor positive (ER+/PR+) pattern. On the other hand, these patients frequently present with clinical signs of a hyperestrogenism (chronic anovulation, infertility, obesity). Primary progestin therapy has been demonstrated to be effective in early well differentiated tumors and in poor operative candidates with response rates ranging from 58-100%.Currently, the therapeutic approach to an early stage EC consists of a staging laparotomy/laparoscopy, including a total abdominal hysterectomy and bilateral salpingo-oophorectomy (TAH-BSO), peritoneal washings, and lymphadenectomy (pelvic and aortic), depending on the pathological risk profile pre- and intraoperatively determined. Therefore, the current standard of surgical approach is preclusive of fertility. The worldwide experience and data on conservative management of EC are, however, still limited. Most of reports based on cases retrospectively collected, harboring potential methodological bias, using different treatments and drugs, and with insufficient follow-up. Some systematic reviews have been published in the last decade, trying to summarize the literature data. Therapeutic results seem to be promising with a regression rate of approximately 75% and relapse occurring in 25-40% of cases, with anecdotical reports of deaths of disease (DOD). The fertility outcome was, however, not satisfying with about 30% pregnancy rate in patients attempting to conceive, and an overall low rate of assisted reproductive techniques (ART) despite the subfertile clinical profile.Therefore, there is a need for a prospective, multicentre cooperative project able to systematically collect data from consecutive patients treated according to defined (not necessarily identical) protocols, concerning the oncological, as well as, the obstetrical outcomes. Moreover, this project could represent the "template" in which a pretreatment fertility counseling, psychological support, and definitive surgery are routinely included according to shared criteria.
JCOG1801 is a randomized phase III trial which was initiated in Japan in August 2019 to confirm the superiority of preoperative chemoradiotherapy followed by surgery plus adjuvant chemotherapy for local relapse-free survival over standard treatment, i.e. surgery plus adjuvant chemotherapy, for previously non-irradiated locally recurrent rectal cancer.
The purpose of this study is to evaluate the safety, tolerability, and preliminary efficacy of INCB057643 as monotherapy or combination with ruxolitinib for participants with myelofibrosis (MF) and other myeloid neoplasms.
The purpose of this study is to demonstrate superiority of macitentan 75 milligrams (mg) in prolonging the time to the first clinical events committee (CEC)-adjudicated morbidity or mortality (M/M) event in participants with symptomatic pulmonary arterial hypertension (PAH) compared to macitentan 10 mg.
The primary purpose of the study is to evaluate the effects of mild and moderate hepatic impairment on PK of tasurgratinib after a single dose administration.
Indication:Patients with Advanced c-MET-positive Non-Small Cell Lung Cancer Phase Ib (China only): Approximately 90 patients Phase Ⅱ (globally): Approximately 78 evaluable patients; addition of at least 6 patients in Safety Run-in (US only)
