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.
This is a randomized controlled study to compare the effectiveness of interactive telephone reminders by a layperson on enhancing compliance with CRC screening by FOBT, when compared with usual care (i.e. no intervention).
Multipurpose solutions (MPS) are the most commonly prescribed regimen to clean, disinfect and rinse rigid lenses. The preservatives used in MPS may cause hypersensitivity and the presence of quaternary ammonium compounds (QAC) may increase development of antiseptic resistance mediated by QAC resistance genes, thus lowering the efficacy of disinfection. Povidone-iodine (PVI) has been safely used as a disinfectant for ophthalmic operations and eye drops. The cleadew GP (Ophtecs, Japan) tested in the current study is a PVI based rigid lens disinfecting solutions which does not employ QAC. If its efficacy and safety can be confirmed in this study, it will be a good alternative rigid lens care regimen for children.
This project aims to study the effects of treatment characteristics on myopia control in orthokeratology by investigating the effects of modified treatment zone by reducing the lens back optic zone diameter on the effect of myopia control. The project will be a two-year randomized, double-masked (examiner - mask axial length only) study conducted at The Hong Kong Polytechnic University recruiting sixty Chinese subjects aged between 6-11. Subjects will be randomly assigned to two ortho-k groups. The Control group will wear KATT BeFree lens with a BOZD of 6mm while the Test group will wear KATT MC lens with a modified BOZD of 5mm.
The purpose of this trial is to evaluate efficacy and safety of pembrolizumab plus standard of care (SOC) chemotherapy with cisplatin and 5-fluorouracil (5-FU) versus placebo plus SOC chemotherapy with cisplatin and 5-FU as first-line treatment in participants with locally advanced or metastatic esophageal carcinoma. The overall primary efficacy hypotheses are as follows: 1. In participants with esophageal squamous cell carcinoma (ESCC), participants whose tumors are programmed cell death-ligand 1 (PD-L1)-positive (defined as combined positive score [CPS] ≥10), ESCC participants whose tumors are PD-L1 positive (CPS ≥10), and in all participants, overall survival (OS) is superior with pembrolizumab plus SOC chemotherapy compared with placebo plus SOC chemotherapy. 2. In participants with ESCC, participants whose tumors are PD-L1 positive (CPS ≥10), and in all participants, progression-free survival (PFS) according to Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 as assessed by investigator is superior with pembrolizumab plus SOC chemotherapy compared with placebo plus SOC chemotherapy.
This is a prospective cohort study building upon the existing cohort study on the effectiveness of the Trekkers Family Enhancement Scheme. This study will sample 200 low-income parent-child pairs and follow them up for 24 months with yearly assessment on parental stress and child health using both subjective measures and objective physiological parameters. Additional data on parenting style, neighbourhood cohesion, child physical assault and neglect potential, parental mental health and HRQOL and family disharmony will also be collected at each assessment time point for testing mediating and moderating mechanisms between parental stress and child health. The baseline assessment will be carried out in 2016-17 with three repeated assessments after 6 months, 12 months, and 24 months.
Stroke survivors have higher risks of falling compared to other healthy non-stroke adults. Stroke patients' balance can be trained by Kinect-based training that enable user friendly and interactive training.
The present study will examine (1) the effectiveness of regular messages and semi-personalized instant messaging with AWARD brief advice and active referral to smoking cessation (SC) services and (2) explore the use of CBPR model to build capacity and to engage community partners in taking on this important public health issue for sustainability in the community. In addition, a process evaluation will be conducted to assess the effectiveness of the recruitment activity and how it is linked with the overall program outcomes.
Bioresorbable vascular scaffold (BVS, ABSORB BVS1.1, Abbott Vascular) has been approved (CE mark) and is used in daily clinical practice. While recent randomized controlled trials comparing BVS versus metallic drug-eluting stent showed higher risk of definite or probable device thrombosis after BVS implantation, the causes underlying thrombotic events occurring beyond one year after scaffold implantation remain unclear and require investigation in an independent manner. The INVEST registry is a world-wide, multi-center, observational, retrospective, investigator-initiated registry, which will include any patients who suffered from very late (>1 year) scaffold thrombosis, underwent optical coherence tomography (OCT) at the time of thrombosis and provided informed consent for the further use of their health related data for this registry.
The primary objective of this study is to evaluate the safety and tolerability and virologic response of tenofovir alafenamide (TAF) in virologically suppressed chronic hepatitis B participants with renal and/or hepatic impairment.
This study is a long-term study of ataluren in participants with nonsense mutation Duchenne muscular dystrophy.
