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 this study is to evaluate the safety and efficacy of ramucirumab in participants with hepatocellular carcinoma (HCC) and elevated baseline alpha-fetoprotein. Participants will be randomized to ramucirumab or placebo in a 2:1 ratio (Main Global Cohort and China Maximized Extended Enrollment [MEE] Cohort). Participants may also receive ramucirumab if eligible to be enrolled in Open-Label Expansion (OLE) Cohort.
The primary objective of the study is to evaluate the safety and tolerability of single and multiple intravenous (IV) infusions of Aducanumab in Japanese participants with mild to moderate Alzheimer's Disease (AD). The secondary objectives of this study are as follows: To evaluate the serum pharmacokinetics (PK) of Aducanumab after single and multiple intravenous (IV) infusions of Aducanumab; To evaluate the effect of single and multiple IV infusions of Aducanumab on immunogenicity.
The purpose of this study was to understand the biological and functional changes after one year of smoking cessation and to collect data on a broad range of biomarkers of exposure (BoExp) and biomarkers of effect (BoE).
The main purpose of this study is to evaluate the safety and efficacy of the study drug known as tadalafil in participants with benign prostatic hyperplasia who are being treated with an alpha1 blocker. This study has two treatment periods. Participants will receive tadalafil or placebo in each treatment period.
To evaluate the suitability (i.e. number of tests completed and number of participants completing the tests, variance estimate of baseline and of the change from baseline values) of neurocognitive tests and functioning scales in view of their use in future multicenter, multinational clinical efficacy trials testing a putative cognitive enhancer for individuals with Down syndrome aged 6-30.
This study is a post-marketing surveillance of lenvatinib in participants with unresectable thyroid cancer. The objectives of this study are to capture unknown adverse reactions, incidences of adverse drug reaction, efficacy, factors considered to have effect to safety and effectiveness, and incidences of hypertension, hemorrhagic events and thromboembolic event, and liver disorder.
The primary objective in this study is to collect post-marketing information on Riociguat safety.Thus, the information on adverse events (AEs) and adverse drug reactions (ADRs) that occur within the first 12 months and in the following 6 -year observation at most, after starting Riociguat treatment under the routine clinical practice will be collected. The secondary objectives are collecting information on Riociguat effectiveness, such as 6-Minute Walking Distance (6MWD) Test. Since it is assumed that Riociguat is for long-term use, information on Pulmonary Arterial Hypertension (PAH) clinical worsening will also be surveyed once a year.
The purpose of this study is to determine whether TBI-1401(HF10), a spontaneously attenuated mutant of Herpes Simplex Virus Type 1 (HSV-1), is safe and tolerable in the treatment of solid tumors with superficial lesions.
To evaluate the safety and tolerability of perampanel given as an adjunctive therapy in participants with epilepsy. This study will be continued until perampanel is commercially available.
The main purpose of this study is to evaluate the safety and efficacy of the study drug ramucirumab in combination with docetaxel in participants with urothelial cancer who failed prior platinum-based therapy.
