There are about 3753 clinical studies being (or have been) conducted in Hong Kong. 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.
Active parathyroid glands among renal dialysis patients contribute to calcified and hardened blood vessels. Such damage to the blood vessels, in turn, takes a significant toll in terms of cardiovascular disease. Calcimimetics has been suggested to lower the risk of vascular calcification. Role of cinacalcet was demonstrated in animal model but human data are lacking. The investigators designed an open label pilot study to evaluate the effect of cinacalcet in 20 peritoneal dialysis patients with inadequately controlled secondary hyperparathyroidism despite standard treatment. The primary outcome is the aortic pulse wave velocity at 26 and 52 months after cinacalcet treatment.
This is a Phase 3 multicenter, randomized study evaluating the safety and efficacy of ramucirumab DP plus BSC as a double-blind, placebo-controlled (placebo plus BSC) comparison. Approximately 544 participants, at least 18 years of age, with Child-Pugh score < 7 and diagnosed with hepatocellular carcinoma will be randomized. Participants must have received sorafenib as first-line systemic treatment for hepatocellular carcinoma (HCC), and must have discontinued sorafenib prior to entering the study. Hypothesis: This sample size will allow differentiation of the expected increase in median overall survival (OS), from 8 months in the placebo arm to 10.67 months in the ramucirumab arm. Upon registration and completion of screening procedures, eligible participants with HCC who have disease progression during or following first-line therapy with sorafenib, or were intolerant to this agent, will be randomized to receive either ramucirumab DP or placebo. The treatment regimen will be continued until radiographic or symptomatic progression, the development of unacceptable toxicity, noncompliance or withdrawal of consent by the participant, or investigator decision.
Irritable bowel syndrome is a common digestive disorder worldwide. However, there is no effective treatment of irritable bowel syndrome. Visceral pain thresholds in response to stress are lower in patients with IBS compared to healthy volunteers, but the triggers to visceral hypersensitivity remain largely unknown. Animal models suggest roles for both host immune response and intestinal bacteria in the induction of visceral hypersensitivity. For instance colorectal distension increased in association with an alteration in bacterial flora induced by antibiotic therapy, which suggest a relationship between bacterial gut content and visceral afferent processing. Intestinal bacteria play a significant role in inducing IBS. Clinical studies have shown that manipulation of the commensal microbiota with probiotic bacteria, in particularly preparations that contain bifidobacteria, can alleviate IBS symptoms. Serotonin (5-HT) plays a crucial role in the regulation of gastrointestinal physiology and alterations in mucosal serotonin signaling is a possible mechanism of altered function and sensation in patients with IBS. Impairment of serotonin reuptake transporter (SERT) expression and function may also play a role in IBS. The investigators hypothesise that bacteria modulate sensory afferent and serotonin signaling necessary for visceral sensation and that these pathways can be targeted for therapy of IBS using probiotic bacteria. The first part of this study will be a cross-sectional study comparing the colonic microbiota and SERT polymorphisms in IBS patients and healthy controls. The second part will be an open-label pilot study to assess the effects of oral probiotic bacteria in visceral hypersensitivity and mucosal microbiota in patients with IBS. Clinical response will be assessed based on IBS symptom score and rectal sensitivity, and changes in mucosa microbiota will be measured using 454 pyrosequencing. This proposal will provide novel data on gut microbiota in Asian IBS patients, and explore the mechanisms underlying visceral hypersensitivity to direct future targeting of therapy in IBS.
Dental procedures such as wisdom tooth removal evoke very high levels of patients' anxiety and it is, therefore, common practice to provide concomitant pharmacologic sedation. Sedative agents can be administered by the oral, rectal, intra muscular and intravenous routes. The oldest, safest and most convenient route at present is the oral route. However, as Uygur-Bayramicli et al. mentioned that administering the drugs orally can result in problems like delayed effect. Intranasal administration is a straightforward procedure. It is simple and relatively painless. Although it may be objectionable, less patient cooperation is required than with oral administration, especially in which the child must swallow the medication. Many studies on dental sedation have been carried out by anesthesiologists but there is no ideal drug that can offer effects of both sedation and analgesia. Some drugs offer only one effect and others are not safe enough for clinical use. Midazolam, a benzodiazepine drug, is the traditional choice for sedation, but it has properties such as relatively slow onset and no analgesia. Propofol is an alkylphenol sedative and hypnotic agent with a rapid onset and offset. It has been used in patient controlled sedation before. But it has no analgesic properties. It can provide some antegrade amnesia, but it is not as reliable an amnestic as the benzodiazepine drugs. Because of these characteristics, propofol often is supplemented with narcotics and benzodiazepines. Although not irritant, it can cause pain during intravenous infusion. A new drug, an alpha agonist with its relatively high ratio of α2/α1-activity (1620:1 as compared with 220:1 for clonidine) of theα2 receptor is dexmedetomidine. This property may lead to more potent effects of both sedation and analgesia without unwanted cardiovascular effects fromα1 receptor activation. Most of the data evaluating the use of dexmedetomidine in the intensive care unit (ICU) were obtained in the immediate postoperative period, mainly in patients who underwent open-heart surgery. Currently, clinicians are awaiting studies in broader patient populations. In the studies that have been completed to date, sedation has been attained easily with maintenance of respiratory function. Patients are readily arousable. There is a minimal increase in blood pressure initially, followed by a slight decrease in blood pressure. Lower dose ranges, avoidance of rapid bolus injection, and a slow rate of administration tend to decrease these circulatory side effects. So many clinical studies have shown that it can be well and safely used intravenously, intramuscularly and transdermally. Although not an officially technique, there are also reports of intranasal administration resulting in fairly predictable onset in both adults and children. The investigators propose that intranasal can help to improve postoperative pain relief with better sedation.
The aim of the present study is to investigate the safety of BI 10773 treatment in patients with Type 2 Diabetes Mellitus and high cardiovascular risk.
The goal of the MultiSENSE study is to collect chronic information from multiple sensors in an implanted device for evaluation in heart failure patients.
This is an open-label, single arm, multi-center, multi-national, adaptive design, dose-escalation Phase 1/2 study to determine the maximum tolerated dose (MTD) of temsirolimus with daily neratinib, and to determine the safety and efficacy of this combination when given to patients with advanced breast carcinoma, specifically trastuzumab-refractory HER2-amplified disease or triple-negative disease.
Objective: Chronic obstructive pulmonary disease (COPD) is a disease with significant morbidity and incurs heavy utilization of healthcare resources. The direct cost of hospital admissions related to COPD is the single largest source of expenditure in the public hospital system. This study aims to assess whether a comprehensive care programme can decrease the rate of hospital admissions for COPD patients.
The purpose of this study is to determine whether saxagliptin can reduce the risk of cardiovascular events when used alone or added to other diabetes medications
The purpose of this study is to evaluate the efficacy and safety of 2 different doses of canagliflozin compared with placebo in older patients (55 to 80 years of age) with type 2 diabetes mellitus (T2DM) with inadequate control on their current diabetes treatment regimen.
