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.
A randomised trial on the use of luteal phase support in frozen-thawed embryo transfer cycles. The hypothesis of the study is that the use of luteal phase support with human chorionic gonadotrophin would increase the pregnancy rate in frozen-thawed embryo transfer cycles.
This trial is conducted in Africa, Asia, Europe and South America. The aim of the trial is to evaluate efficacy and safety of semaglutide once-weekly versus sitagliptin once-daily as add-on to metformin and/or TZD (thiazolidinedione) in subjects with type 2 diabetes.
The study aims to examine the relationship between early maintenance therapy decisions in first episode psychosis, and the subsequent long-term clinical outcome at 9-10 years by comparing a group of patients who were randomized to discontinue (placebo) or continue medication (quetiapine) in the early stage of their psychotic disorders.
The purpose of the study was to determine whether treatment with a PI3K inhibitor plus letrozole led to an increase in pathologic clinical response and Objective Response Rate compared to treatment with placebo plus letrozole in patients with Breast cancer.
There is no theoretical or practical reason why non-medical personnel such as nurses could not be trained to perform diagnostic colonoscopy with comparable proficiency as medical endoscopists. Nurse endoscopists have been widely accepted in the United Kingdom for the past 15 years as a valuable resource to cope with the increasing demand for endoscopic service, in particular diagnostic colonoscopy for colorectal screening. A pilot study performed in Hong Kong in 2008 has shown that endoscopy nurses can be trained to perform diagnostic endoscopy safely and reliably. This study aims to demonstrate that properly trained nurse endoscopists have a comparable proficiency in performing colonoscopy procedures as their medical counterparts.
This study was designed to evaluate the efficacy and safety of two different dosing regimens of 0.5 mg ranibizumab given as intravitreal injection in comparison to verteporfin PDT in patients with visual impairment due to choroidal neovascularization secondary to pathologic myopia (PM)
The investigators aim to examine the efficacy and safety of using a new citrate containing commercially available solutions (Prismocitrate 18/0) as the regional citrate anticoagulation in continuous renal replacement therapy for critically ill patients.
This was a multicenter, randomized, double-blind, placebo-controlled, parallel-group Phase 2 trial of Sprifermin administered intra-articularly in participants with primary osteoarthritis of the knee and Kellgren-Lawrence Grade 2 or 3. The trial was intended to investigate the efficacy and safety of different intra articular dosages of Sprifermin in these individuals.
Currently, five nucleos(t)ide analogs are approved for the treatment of chronic hepatitis B, namely lamivudine, adefovir dipivoxil, telbivudine, entecavir (ETV) and tenofovir disoproxil fumarate (TDF). ETV and TDF are recommended as first-line therapy by all regional guidelines due to their high anti-viral potency and low risk of inducing resistance. ETV monotherapy for chronic HBV infection is highly effective in both HBeAg-positive and negative treatment-naïve patients. The cumulative probability of maintained virologic suppression with undetectable HBV DNA at year 1, 2 and 3 were 76.5%, 83.0% and 88.3% respectively. TDF is another potent anti-viral treatment for chronic hepatitis B. Up to 72% and 87% of HBeAg-positive and -negative patients achieved undetectable HBV DNA by week 144 of TDF monotherapy. It is also effective in patients with prior exposure to other nucleo(s)tide analogs. Previous studies demonstrated that TDF can be used as an effective rescue therapy in lamivudine or adefovir-treated patients with incomplete virologic response. However, the optimal treatment for patients with suboptimal response to ETV is uncertain. With this background, we will conduct a randomized controlled trial to evaluate the efficacy of TDF switch therapy in patients with incomplete virologic response to ETV treatment.
This is a study to investigate the potential clinical benefit of refametinib when given in combination with sorafenib as first line treatment in patients with unresectable or metastatic HCC carrying a RAS mutation. The study will be conducted in 2 stages. Approximately 95 patients (15 at Stage 1/ 80 at Stage 2) will be accrued to this study to receive treatment. Stage 2 of the trial will only be conducted if at least 5 out of 15 patients at Stage 1 show at least partial response according to an objective criteria to evaluate tumor size based on contrast enhancement [modified response evaluation criteria in solid tumors (mRECIST)] assessed by external independent radiologists. Refametenib is an oral (i.e. taken by mouth) protein kinase inhibitor. A kinase inhibitor targets certain key proteins that are essential for the survival of the cancer cell. By specifically targeting these proteins, refametinib in combination with sorafenib may stop cancer growth. The growth of the tumor may be decreased by preventing these specific proteins from functioning. The primary endpoint (the most meaningful result to be tracked) of this study is based on the rate of response, i.e. the disease getting smaller. The aim is to show that the therapy with refametinib in combination with sorafenib improves the response rate in this patient population compared to historical results observed with the sorafenib only.
