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.
Heart failure (HF) is one of the most important reasons for hospital admission and is associated with high mortality and morbidity. After discharge, up to 40% of patients are readmitted within 6 months and 1-year post-discharge mortality is high. The cost burden of treating patients with HF is high and ~80% of healthcare costs are related to hospital admissions. Sodium-glucose cotransporter-2 (SGLT2) inhibitor is considered one of the four foundational therapies (ACE-I or ARNI, beta-blockers, MRA, and SGLT2 inhibitors) for HFrEF. This is an investigator-initiated, prospective, single-centre, registry that evaluates the change in HRQL as measured by the KCCQ-TSS after the initiation of Dapagliflozin.
This is a single-arm clinical trial to evaluate the efficacy and safety of quadruple immunotherapy with natural killer (NK) cells, anti-GD2 antibody, cytokines (interleukin-2 (IL-2) and granulocyte-macrophage colony stimulating factor (GM-CSF)) and retinoid X receptor gamma (RXRg) agonist spironolactone for paediatric patients with relapsed or refractory neuroblastoma.
Outpatient hysteroscopy can serve as a diagnostic procedure to evaluate for abnormal uterine bleeding, such as menorrhagia or postmenopausal bleeding. This study focuses on the therapeutic aspect of outpatient hysteroscopy, such as myomectomy, polypectomy, intrauterine adhesiolysis and removal of lost intrauterine devices, etc. Apart from the conventional polyp scissors and biopsy forceps, there are also emerging hysterscopic tissue removal systems, such as Truclear®, that can decrease the operation time and increase success of outpatient hysteroscopic operations. On such occasions, the outpatient hysteroscopic operation needs to be re-arranged in an inpatient setting in the operation theatre under regional or general anesthesia. Therefore, improvement in pain management can reduce participants' health care experience, participants' anaesthetic and procedural risks, decrease healthcare costs, and reduce inconvenience to participants. This randomized controlled trial aims at evaluating the effectiveness of non-pharmacological interventions (virtual reality and music therapy) in pain management during hysteroscopic operations. It can hopefully provide more local clinical data to explore the role of nonpharmacological techniques in pain control, hence improve our participants' experience in hysteroscopic operations and the potential of providing more hysteroscopic operations as an outpatient setting.
The goal of this pilot randomized controlled trial is to explore the feasibility of e-health enhanced motor-cognitive interventions for discharged community-dwelling older adults with cognitive frailty in the emergency department and to evaluate the effectiveness of the interventions on (1) cognitive functions, (2) physical functions and (3) frailty status. Participants in the intervention group will receive three-90-minute weekly physical and cognitive training for 12 weeks, facilitated with persuasive technology on smartphones, in addition to the usual care. The control group will receive the usual care. Researchers will explore the feasibility and compare the changes of outcomes between two groups.
The primary objective of this study is to assess the efficacy of a single dose of ravulizumab IV compared with placebo in reducing the risk of the clinical consequences of AKI (MAKE) at 90 days in adult participants with CKD who undergo non-emergent cardiac surgery with CPB.
Hypertension is a common health problem that affects millions of people in the world. Poorly controlled blood pressure (BP) leads to cardiovascular, cerebrovascular and renal complications. Despite the availability of multitudes of anti-hypertensive drugs, the percentage of patients achieving optimal control of hypertension has remained disappointingly low. Resistant hypertension (rHT) is defined as the failure to achieve target BP despite concurrent use of antihypertensive drugs of different classes, with one of them being diuretics. The reported prevalence of this condition ranged from 5 to 30%. Lifestyle modification, enhancing drug compliance, treating of secondary causes, or adding mineralocorticoid receptor antagonist such as spironolactone or eplerenone are well established strategies to treat resistant hypertension. Besides factors such as, activated sympathetic nervous system (SNS) and increased sympathetic outflow was thought to contribute to the development of rHT as well. Autonomic sympathectomy by way of endovascular renal denervation (RDN) was once a hopeful candidate as an adjuvant treatment for patients with rHT and it had shown signals of efficacy in early trials. However, the blood-pressure lowering efficacy was not demonstrated in the larger-scaled, randomized, sham- controlled SYMPLICITY HTN-3 trial. One possible explanation of the lack of efficacy of RDN in this trial was the lower-than-expected BP responses in the RDN group and higher than-expected BP reduction in the control group which raised the speculation that some of the patients recruited were not true rHT as the trial intended to include. The suboptimal anti-hypertensive efficacy of RDN in HTN-3 was also partly attributed to the design of the first-generation RDN catheter, in which only a single electrode is deployed and might not offer sufficient sympathetic denervation as less than half of patients in the SYMPLICITY HTN-3 received 4 quadrants ablation. The second generation SYMPLICITY RDN catheterTM has 4 times electrodes that are arranged in spirally in 90-degree intervals. Theoretically, the newer generation catheter can provide more efficient and extensive denervation in a shorter period of time. Its efficacy was confirmed in SYMPLICITY HTN ON-MED and OFF-MED trial, which confirmed a consistent and durable BP reduction that lasted into 36 months with or without adjuvant anti-hypertensive drugs. BP reduction is only one of the effects of RDN. Previous observational studies of the first generation RDN catheter have shown an inconsistent effect of RDN in left ventricular (LV) remodelling, arrythmia modulation, arterial de-stiffening and quality of life. No report of these effects has been published with the newer generation catheter. Furthermore, vigorous efforts have been put into searching for clinical predictors that can identify patients in whom the BP reduction effect of RDN is most significant. This study aims to investigate the systemic effects of RDN using the new generation SYMLICITY RDN catheterTM in patients with rHT.
Renal sympathetic denervation (RDN) was considered an effective alternative for patients whose blood pressure (BP) is not optimally controlled. The RDN works mainly by selectively disabling the nerves around the renal arteries and reducing blood pressure increase. However, despite the early success showed in the SYMPLICITY HTN-2 trial, the SYMPLICITY HTN-3 trial failed to demonstrate a significant BP reduction when compared to sham-control. incomplete disabling might result in inadequate denervation and were cited as some of the contributors to the nil result in the SYMPLICITY HTN-3 . The new generation of the Symplicity Spyral catheter aims to address some of these issues by altering the configuration of the catheter to allow better apposition to the renal arterial wall and increasing the numbers of electrodes to faciiitate more thorough ablations. However, the adequacy of sympathetic denervation with this new catheter can not be easily assessed at the time of the procedure as there is no simple physiological or biochemical feedbacks that can be monitored during the procedure. Blood pressure response by renal nerve simulation (RNS) during RDN procedure using the previous generation of the Symplicity Flex catheter have been reported to be potential parameter to assess the efficacy during the procedure and predict the BP response 6 months after RDN. The feasibility of RNS guided RDN procedure using the new generation of Symplicity Spyral catheter has not been reported. We therefore aim to explore the feasibility of RNS guided RDN with Symplicity Spyral Radiofrequency Catheter in patient with resistant hypertension.
Nitrogen-containing bisphosphonates (N-BPs; such as alendronate and zoledronate) are commonly used in the treatment of osteoporosis and fracture prevention, in which zoledronate has a proven better efficacy than alendronate. In 2018, our real-world propensity score matched study showed that the use of N-BPs was significantly associated with reduced risk of myocardial infarction and stroke in hip fracture patients. In addition to cardiovascular diseases, both preclinical study and sensitivity analysis also suggest evidence for N-BPs in pneumonia prevention. Moreover, a pragmatic clinical trial is developed to evaluate effect of the tested intervention in real-life routine clinical practice since traditional explanatory radomised controlled trial (RCT) may have poor generalizability due to highly selected patients and controlled environments. This study aims to evaluate if zoledronate reduces risk of pneumonia in hip fracture patients using pragmatic clinical trial approach. This is an open-label, multi-centre, pragmatic, randomised controlled trial. Patients will be recruited from 4 hospitals, namely Caritas Medical Centre, Prince of Wales Hospital, Queen Mary Hospital, and United Christian Hospital. Age, sex, body mass index, eGFR, history of fracture, chronic respiratory diseases, and other medical history, will be measured and recorded at recruitment.
This study aims to examine the comparative effectiveness of different exercise frequencies (once-a-week vs. thrice-a-week) for reducing liver fat in centrally obese adults with non-alcoholic fatty liver disease (NAFLD), with weekly exercise volumes aligned with the World Health Organization's physical activity recommendations.
CKJX839D12302 is a pivotal Phase III study designed to test the hypothesis that treatment with inclisiran sodium 300 milligram (mg) subcutaneous (s.c.) administered on Day 1, Day 90, and every 6 months thereafter in patients at high cardiovascular (CV) risk without a prior major atherosclerotic cardiovascular disease (ASCVD) event will significantly reduce the risk of 4-Point-Major Adverse Cardiovascular Events (4P-MACE) defined as a composite of CV death, non-fatal myocardial infarction (MI), non-fatal ischemic stroke, and urgent coronary revascularization, compared to placebo.
