There are about 36818 clinical studies being (or have been) conducted in China. 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 test the therapeutic ratio of accelerated radiotherapy and/or chemotherapy on locally advanced nasopharyngeal carcinoma.
Idiopathic or functional constipation is a common disorder, affecting up to 20% of the population depending on demographic factors, the sampling situation and the definitions used. Constipation is a symptom of many diseases and is a collective term, used by the patient to imply that stools are too hard, too infrequent or too difficult to pass. A recent survey conducted in Hong Kong showed a prevalence of 14% according to the Rome criteria. Based on an epidemiological study in US, there were 2.5 million annual physician visits for this problem. Exact epidemiological data however are lacking, mainly because of the difference between self-reported constipation and scientifically defined constipation. Treatment of constipation is usually based on increased dietary fiber and supplementation with bulking agents, exercise, and habit training. However, often only partial relief is obtained, and the majority of patients use non-bulking laxatives on a regular basis without medical supervision. Chronic use of non-bulking laxatives is often inappropriate3, and may lead to side effects such as dependency and progressive tolerance, electrolyte imbalance, and, for the anthraquinones, melanosis coli. In addition, stimulant laxatives may damage the myenteric plexus4, resulting in cathartic colon5. A more appropriate approach to the therapy of constipation consists of physiologically stimulating intestinal motility. Tegaserod, an aminoguanidine indole compound, is a representative of a new class of 5-HT4 agonists, with regard to both chemistry and pharmacology. Activation of 5-HT4 receptors triggers the release of neurotransmitters from the enteric nerves resulting in increased contractility and stimulation of the peristaltic reflex. In animal models, tegaserod acts as a motility-enhancing agent, exerting activity throughout the gastrointestinal tract11. Tegaserod has also been shown to significantly accelerate bowel transit in healthy volunteers and in patients with constipation-predominant irritable bowel syndrome (C-IBS). Based on the pharmacodynamic properties, tegaserod is a promotile compound suitable for the treatment associated with small and/or large bowel dysfunction e.g. constipation. From phase III adequate and well-controlled studies in patients with C-IBS it has been shown that tegaserod was effective in relieving symptoms of C-IBS. The effect was seen as early as the first week of treatment with sustained effects over 12 weeks. Both tegaserod 4 mg/d (2 mg bid) and 12 mg/d (6 mg bid) significantly increased bowel frequency and decreased stool consistency. It is proposed to test both doses for the phase III program in chronic constipation. The aim of this study is to demonstrate the effect of tegaserod on bowel habits in patients suffering from chronic idiopathic constipation.
The purpose of the study is to compare alfuzosin GITS once daily versus placebo in achieving a successful TWOC after AUR due to BPH, among Chinese males in Hong Kong, and in delaying or avoiding a TURP.
The purpose of the study is to compare two alpha blockers, terazosin and doxazosin GITS, in achieving a successful TWOC after AUR due to BPH, among Chinese males in Hong Kong, and in delaying or avoiding a TURP.
The purpose of this study conducted in Asia-Pacific was to evaluate the efficacy and safety of Sorafenib in combination with paclitaxel and carboplatin versus placebo in combination with paclitaxel and carboplatin for chemonaive patients with unresectable stage IIIB (with effusion) or stage IV NSCLC. However, as indicated below, the study was terminated prematurely when the results from Study 11961 (NCT00300885), an earlier Phase 3 study of similar design in subjects with advanced NSCLC, showed an overall lack of efficacy and increased mortality in subjects with squamous subtype. The data available is presented as descriptive analyses, due to the limitations of implementing the statistical analysis plan.
This is a Phase III, multicenter, open-label extension, single-group study in male and female outpatients with mild-to-moderate Alzheimer's disease (AD) who have completed AVA105640. All subjects will receive rosiglitazone extended-release (RSG XR) 4mg once daily for the first 4 weeks of the study followed by 8mg RSG XR. Subject participation will last until one of 5 conditions applies. After a 52-week open-label treatment phase, subjects will attend a final Follow-Up Visit 6 weeks after the end of treatment. The primary objective of this study is to evaluate the long-term safety and tolerability of RSG XR in subjects with mild-to-moderate AD who have completed AVA105640. The secondary objective of this study is to explore further the long-term efficacy of RSG XR in terms of cognitive function and overall clinical response as a function of apolipoprotein E (APOE) e4 allele status
The purpose of this study was to determine whether, in patients with type 2 diabetes and pre-existing disease of the heart and the circulatory system and/or the kidney, aliskiren at a target dose of 300 mg once daily (compared to placebo), on top of conventional treatment, reduces death and disease caused by the heart, the circulatory system and the kidney. AMENDMENT 4 RATIONALE (MARCH 2012) : Protocol amendment 4 served to address the data monitoring committee recommendation dated 14 Dec 2011 to discontinue study treatment in all participating patients. It also addressed the subsequent Health Authorities request to implement a 12 month safety follow-up period (actual duration was 9 months in average) post study drug discontinuation.
The purpose of this study is to determine whether Betamarc is effective in improving the appetite and reversing weight loss in patients with advanced Non-Small Cell Lung Cancer.
Local study in China and Hong Kong to evaluate safety and efficacy in lapatinib + capecitabine in women with Human epidermal growth factor receptor 2 (HER2) positive advanced or metastatic breast cancer.
The objectives of this study are to compare in nucleoside treatment-naïve subjects, the efficacy and safety of clevudine 30 mg once daily versus adefovir 10 mg once daily, each as monotherapy, for 48 weeks, 72 weeks, and 96 weeks.
