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.
Primary Objective: - Response rate (by contrast CT scan) Secondary Objectives: - Progression-free survival (PFS) - Overall survival (OS)
The main aim of this oral health intervention project is to compare the effect of providing 1) professional oral hygiene instruction alone versus 2) professional oral hygiene instruction plus adjunctive Chlorhexidine mouth rinse versus 3) professional oral hygiene instruction plus adjunctive assisted tooth brushing and Chlorhexidine mouth rinse, on the oral health condition, the general health condition and health-related quality of life (HRQoL) of patients with stroke who are receiving hospital-based rehabilitation. An additional aim is to assess potential longer term oral intervention-related health and HRQoL outcomes.
Approximately 30% percent of subjects with partial seizures are refractory to treatment with single or combination antiepileptic drugs. The present study will compare the efficacy of two different dosages of pregabalin CR dosed once daily as compared to placebo, when used as adjunctive therapy in subjects requiring adjunctive therapy for partial onset epilepsy, using a randomized, parallel group design.
This study will evaluate the efficacy and safety of brivaracetam at doses of 100 and 200mg/day compared to placebo as adjunctive treatment in adult focal epilepsy subjects with partial onset seizures not fully controlled despite current treatment with 1 or 2 concomitant antiepileptic drugs.
Both Billroth II and Roux en Y are acceptable techniques of reconstruction after subtotal gastrectomy, however the debate one which is better remains unanswered. The aim of this study is to compare Billroth II and Roux en Y reconstruction techniques after radical distal subtotal gastrectomy for gastric cancer in terms of postoperative outcomes and quality of life. The investigators hypothesize that Roux en Y will have lesser gastrointestinal symptoms and reflux problems when compared to Billroth II reconstruction. Patients with resectable gastric cancer meeting the inclusion criteria will be consented and enrolled. Data on demographics, nutrition, gastrointestinal symptoms, and quality of life will be collected. They will be randomized after completion of distal subtotal gastrectomy to under go either Roux en Y or Billroth II reconstruction. Surgery data will be collected post-operatively. At 6 months follow up a repeat nutritional assessment using clinical and biochemical parameters will be carried out. The biochemical markers are part of routine follow up. The final assessment will be at the one year post surgery visit when by interview using EORTC 30 questionnaire quality of life data, gastrointestinal symptoms and nutritional assessment and surgery data for recurrence will be repeated. At one year patients will also have upper gastrointestinal endoscopy, which is part of routine follow up. At endoscopy stump gastritis will be graded and esophageal reflux assessed as per Los Angeles classification. It is postulated that 5% of the patients on Roux en Y reconstruction will experience poor clinical symptoms compared to 25% of those on Billroth II based on reflux symptoms. To achieve a statistical significance with 95% power and a 2-sided test of 5% for this 20% clinical difference, 80 subjects for each arm will be required. Factoring a 10% attrition rate for mortality and lost to follow up, a total of 160 subjects to be randomized equally will be recruited.
This is a phase I, dose escalation trial of MVA-EBNA1/LMP2 vaccine across a pre-defined range of doses in patients in remission having had an EBV+ nasopharyngeal carcinoma (NPC).
The purpose of this study is to assess the efficacy and safety of multiple doses of vortioxetine, once daily (QD), in participants with major depressive disorder.
This is a phase I/II study to evaluate dose limited toxicity and efficacy of Torisel
VEGF Trap-Eye will be tested for safety and efficacy in patients with vision loss due to choroidal neovascularization secondary to pathologic myopia. This will be a placebo-controlled trial. 3 out of 4 patients will receive an injection of VEGF Trap-Eye into the affected eye (and repeated injections if required), and 1 out of 4 patients will receive a sham injection requiring no needle stick, but making the patient unaware of whether or not he received active treatment. Outcome of the two treatment groups will be compared after 24 weeks. From week 24, sham patients may receive active treatment. Total duration of the study will be 48 weeks.
This is an open-label, single arm, phase 2 clinical trial evaluating the activity and safety of single-agent axitinib in recurrent or metastatic NPC patients who failed at least one line of platinum based chemotherapy.
