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.
- Gefitinib is an orally active epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI). However, 20-30% of patients with EGFR-activating mutations show intrinsic resistance to EGFR-TKI. - EGFR-mutant non-small cell lung cancer (NSCLC) cells with BIM (BCL2L11) deletion polymorphism show the impaired generation of BIM with the proapoptotic BH3 domain, as well as resistance to EGFR-TKI-induced apoptosis. - Both BIM polymorphism (12.9%) and EGFR mutations (50% in lung adenocarcinoma) are more prevalent in the East Asian than in Caucasian populations. BIM is a BH3-only proapoptotic member of the Bcl-2 protein family. BIM upregulation is required for apoptosis induction by EGFR-TKI in EGFR-mutant NSCLC. - Vorinostat (suberoylanilide hydroxamic acid [SAHA]) is a small-molecule inhibitor of histone deacetylase (HDAC) and induces cell differentiation, cell cycle arrest, and apoptosis in several tumor cells. HDAC inhibition can epigenetically restore BIM function and death sensitivity of EGFR-TKI in patients with EGFR-mutant NSCLC in whom resistance to EGFR-TKI is associated with a common BIM polymorphism. EGFR-TKI resistance due to the BIM polymorphism may be able to be circumvented in combination with HDAC inhibition of vorinostat with gefitinib in NSCLC.
The study is to explore the effectiveness of omega-3 fatty acids and mindfulness-based stress management program to maintain healthy mental state in hospital nurses. The participants will be junior nurses who work in inpatient wards and are not clinically depressed. The participants will be randomly allocated to four intervention arms: 1) Mindfulness-based stress management program plus omega-3 fatty acids pills ; 2) Mindfulness-based stress management program plus placebo pills; 3) Psychoeducation leaflet plus omega-3 fatty acids pills; and 4) Psychoeducation leaflet plus placebo pills. Thirty participants will be allocated to each arm. These interventions will terminate until three months from registration for each participant. Information about depression and anxiety symptoms (primary outcome), insomnia, burnout, presenteeism, quality of life, sick leave, consultation about mental state of herself, and oxidative stress will be collected at 3 months, 6 months (primary time point) and 12 months from registration for each participant.
The purpose of this study is to examine the differences in perceived health, psychosocial functioning, behavioral outcomes and quality of life of adults with congenital heart disease who are living in different areas of the world, and how these differences can be understood (e.g., differences in sense of coherence or illness perceptions).
The objective of this Phase III study is to evaluate the efficacy of nintedanib in patients with metastatic colorectal cancer (mCRC) after failure of previous treatment with standard chemotherapy and biological agents.
FOLFIRINOX regimen was recently presented at an international oncology meeting and represents a new standard regimen in the treatment of metastatic pancreatic cancer. FOLFIRINOX is one of the high response rate treatment regimen , the investigators considered as a promising treatment as neoadjuvant chemotherapy . On the other hand , incidences of grade 3 or 4 neutropenia , febrile neutropenia and diarrhea were significantly higher in the FOLFIRINOX group compared with gemcitabine group. Therefore, it was decided to consider the balance of safety and efficacy as a preoperative chemotherapy, the investigators use the FIRINOX regimen by eliminating LV and bolus 5-FU, and irinotecan reduced to 150mg/m2 of 180mg/m2 from FOLFIRINOX regimen
The purpose of this study is to evaluate PK, PD and safety of a single oral dose of MT-1303 in subjects with Crohn's disease.
This was a non-randomized, open-label, phase II study to assess the efficacy and safety of eltrombopag in Japanese moderate or more severe aplastic anemia (AA) subjects with a platelet count <30,000/microliter who were refractory to anti-thymocyte globulin (ATG)-based immunosuppressive therapy (IST), who have relapsed after ATG-based IST, or who are ineligible for ATG-based IST. Eltrombopag was expected to improve trilineage blood cells and decrease transfusion frequency based on the result from the previous study in patients with severe AA. This study used the hematologic response rate, defined as the proportion of subjects showing improvement in at least one of the three blood cell lineages or a decrease in blood transfusion volume, as the primary endpoint. A total of 36 subjects were screened and 21 were enrolled in the study. Treatment with eltrombopag started at 25 milligram (mg)/day and increased by 25 mg/day every 2 weeks according to the platelet count up to 100 mg/day. Response assessment was performed at 3 months after starting the study treatment (Week 13). Subjects in whom the treatment was assessed as effective continued with the study treatment. Subjects in whom the treatment was assessed as effective (when meeting any of the response criteria) at 6 months after starting the study treatment (Week 26) might enter the extension phase and continue the treatment with eltrombopag. The primary endpoint was the hematologic response rate at Week26.
The efficacy and safety of a novel oral Xa inhibitor for stroke and systemic embolism, namely rivaroxaban, in non-valvular atrial fibrillation patients are evaluated in Japanese clinical practice.
This study (Protocol No. E6011-J081-002) is a single-center, randomized, double-blind, placebo-controlled, single ascending dose (SAD) study to evaluate mainly the safety and tolerability of a single subcutaneous administration of E6011. A total of 32 subjects will be randomized into four cohorts (50, 100, 200 and 400 mg groups). Of eight subjects per cohort, six subjects will receive the single subcutaneous E6011 administration and two subjects will receive the single subcutaneous placebo administration.
This trial is conducted in Asia. The aim of the trial is to investigate the pharmacokinetics (the exposure of the trial drug in the body), pharmacodynamics (the effect of the investigated drug on the body), and the safety and tolerability of semaglutide in healthy male Japanese and Caucasian subjects.
