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.
XIENCE 28 Global Study is a prospective, single arm, multi-center, open label, non-randomized trial to further evaluate the safety of 1-month (as short as 28 days) dual antiplatelet therapy (DAPT) in subjects at high risk of bleeding (HBR) undergoing percutaneous coronary intervention (PCI) with the approved XIENCE family (XIENCE Xpedition Everolimus Eluting Coronary Stent System [EECSS], XIENCE Alpine EECSS, XIENCE PROX EECSS, XIENCE ProA EECSS or XIENCE Sierra EECSS of coronary drug-eluting stents
Caring for people with dementia (PWD) poses many challenges which may cause high levels of caregiver stress. This study aims to investigate the effects of a modified Mindfulness-based Cognitive Therapy for stress reduction in the family caregivers of PWD. A prospective, single-blind, parallel-group randomized controlled trial (RCT) of 76 family caregivers of PWD will be recruited and randomized to either the MBCT or the control groups.The primary outcomes (stress) and secondary outcomes (anxiety, depression, burden, quality of life and resilience) will be measured at immediate post-intervention (T1) and at 3 months follow up (T2) which will be compared with the baseline (T0). Mixed repeated measure MANOVA will be performed to assess the effects of time, group, and time-group interaction on all outcome measurements.To understand the therapeutic components and identify the strengths, limitations, and difficulties of the MBCT program, process evaluation will be conducted through focus group interviews with 15 participants from the MBI group. It is hypothesized that the MBCT group will have a significantly greater reduction of stress (primary outcome) and improvement in the secondary outcomes, namely depression, anxiety, and burden, at T1 and/or T2 than the control group.
Study to investigate if the study drug ticagrelor and ASA is more effective than Placebo (inactive tablet) and ASA in preventing new stroke events
Background: Previous studies have confirmed that most patients with idiopathic REM sleep behaviour disorder (iRBD) eventually develop neurodegenerative diseases. In addition, REM sleep without atonia (RSWA), a hallmark of RBD feature, is a significant predictor of development of neurodegenerative diseases in patients with iRBD. Some preliminary studies have implied that isolated RSWA in the absence of RBD symptoms may also indicate neurodegeneration. However, this speculation needs to be confirmed by more refined study with sophisticated measures in both RSWA and markers of neurodegeneration Objectives: 1) to determine the differences in striatal dopamine transmission and other markers of neurodegeneration among individuals with isolated RSWA and healthy controls; 2) to examine the correlation of severity of RSWA with striatal dopamine transmission. Design: Case-control study Setting: Community-based sample Participants: 1) iRBD first degree relatives with isolated RSWA (n=18) 2) iRBD first degree relatives without isolated RSWA (n=18) 3) Community-based health controls without isolated RSWA (n=18) Main outcome measures: 1. The dopamine transmission as measured by triple-tracer PET/ CT imaging protocol including 18F-DOPA, 11C-Raclopride and 18F-FDG images; 2. Brain glucose metabolism and neurocognitive measures; 3. Severity of EMG activity during REM sleep
Irradiation of the parotid gland with subsequent long-term xerostomia is a well-recognized complication after radiotherapy for head and neck (HAN) cancers. A number of studies have shown that IMRT could minimize the radiation dose to the parotid glands and hence the risk of developing xerostomia. The benefit of IMRT has also been demonstrated in prior dosimetric and non-randomized studies in NPC patients. In 2007, the investigators have published the prospective randomized study of IMRT versus 2DRT in early stage NPC patients. In the study, IMRT had lower incidence of observer-rated severe xerostomia, higher parotid and whole saliva flow rate, than patients in 2DRT arm at 1 year after treatment. However, there was no significant difference in patient-reported outcome, i.e. subjective xerostomia scoring, between the 2 arms. The underlying reason for the incoherent findings in terms of objective and subjective xerostomia outcome remains uncertain. One of the possible explanations for this observation could be the better parotidsparing with IMRT alone may not entirely sufficient to maintain oral cavity lubrication while the other mucin-secretory salivary gland protection is also essential. Another possible explanation for the insignificant improvement in patient-reported outcome with IMRT is the short follow-up time. Gradual recovery or improvement in various quality of life parameters was not uncommonly seen several years after definitive radiotherapy for HAN cancer patients. There is much interest in studying the long term clinical outcome, especially the treatment-related complications, for the patients who had randomized and treated in the prior presented prospective study. In this study, the long term results, in particular the xerostomia rating will be assessed and compared in NPC patients who had participated in the prior reported prospective randomized study of IMRT vs 2DRT.

The purpose of this study is to demonstrate that injection cycles consisting of a single administration of paliperidone palmitate 6-month (PP6M) are not less effective than 2 sequentially administered injections of paliperidone palmitate 3-month PP3M) (350 or 525 mg eq.) for the prevention of relapse in participants with schizophrenia previously stabilized on corresponding doses of paliperidone palmitate 1-month (PP1M) (100 or 150 mg eq.) or PP3M (350 or 525 mg eq.).
The purpose of this study is to evaluate the clinical safety and effectiveness of the Resolute Onyx stent in subjects deemed at high risk for bleeding and/or medically unsuitable for more than 1 month DAPT treatment receiving reduced duration (1 month) of DAPT following stent implantation.
The study aims to test the effect a smartphone-based intervention on primary school students and their parents' attitudes towards tobacco industry and their tobacco-related communications.
