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.
Tipepidine (3-[di-2-thienylmethylene]-1-methylpiperidine) has been used solely as a nonnarcotic antitussive in Japan since 1959. The safety of tipepidine in children and adults has already been established. It is reported that tipepidine inhibits G-protein-coupled inwardly rectifying potassium (GIRK)-channel currents. The inhibition of GIRK channels by tipepidine is expected to modulate the level of monoamines in the brain. We put forward the hypothesis that tipepidine can improve attention deficit/hyperactivity disorder (ADHD) symptoms by modulating monoaminergic neurotransmission through the inhibition of GIRK channels. The purpose of this double-blind, placebo-controlled trial is to confirm whether treatment with tipepidine can improve symptoms in pediatric patients with ADHD.
The purpose of the study was to assess the use of Multikinase Inhibitors (MKIs) in the treatment of patients with a progressive differentiated thyroid carcinoma (DTC) refractory to radioactive iodine (RAI) who do not have any symptoms.
This is a Phase III, global, multicenter, open-label, two-arm, randomized, controlled study designed to evaluate the efficacy and safety of atezolizumab compared with chemotherapy in participants with locally advanced or metastatic urothelial bladder cancer (UBC) who have progressed during or following a platinum-containing regimen. The anticipated time on study treatment is based on continued clinical benefit, i.e., until disease progression or unacceptable toxicity. The target sample size is 931 participants.
To evaluate the safety and efficacy of eculizumab in the treatment of refractory generalized myasthenia gravis (gMG) as an extension study for the participants who previously completed Study ECU-MG-301(NCT01997229).
Post-marketing surveillance to investigate the clinical safety and effectiveness in patients of all implantation of Gliadel with malignant glioma in the actual medical setting.
The objective of this study is to determine the survival status of patients enrolled in study GLI01S (all-case observational study).
To determine the appropriateness of the dose of nintedanib 200 mg b.i.d. plus docetaxel 75 mg/m2 as starting dose by evaluating the safety in Japanese patients with body surface area (BSA) <1.5 m2 and locally advanced or metastatic adenocarcinoma subtype non-small cell lung cancer (NSCLC) after failure of first line platinum- based chemotherapy
The purpose of the present study is to evaluate the effect of the extract of the flour fermented with Bacillus subtilis var natto DC-15 on postprandial glucose level in subjects with prediabetes.
The objective of this survey is to confirm the safety of Suglat Tablets when used in the elderly.
The overall objective is to assess the effect of once daily tiotropium + olodaterol fixed dose combination compared to 5 µg tiotropium (both delivered with the Respimat® inhaler) on moderate to severe COPD exacerbation in patients with severe to very severe COPD.
