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.
Safe and effective severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines may reduce the transmission of and achieve population immunity against the COVID-19 pandemic, which accounted for more than 3.75million deaths worldwide. With World Health Organization's (WHO) effort on ensuring equitable access to COVID-19 vaccines, vaccination rate may increase in the near future. On the other hand, vaccination hesitancy has emerged as a major hindrance on the global vaccination campaigns in certain areas due to safety concerns, social factors, and public health policies. For instance, a recent survey conducted in Hong Kong showed a low vaccine acceptance rate of 37%. Long-term safety concerns and post-vaccination events relayed by the social media maybe reasons for vaccination hesitancy. Among which, cerebrovascular accidents (CVA) after vaccination were one of the most frequently reported post-vaccination events. These reports ranged from ischemic strokes in elderly patients with multiple cardiovascular co-morbidities, to hemorrhage strokes in otherwise "young-and-fit" adults. While many of these events were investigated by the COVID-19 immunization expert committee, an important premise to address the apprehension of CVA after vaccination is the provision of evidence-based information of the impact of COVID-19 vaccines on brain health. In this prospective, longitudinal, observational study, we aim to elucidate the relationship between COVID-19 vaccines and cerebrovascular health in healthy citizens in a population-based cohort.
This randomized controlled trial aims to examine the effectiveness of the Acceptance and Commitment Therapy-based Asthma Management Training Program on the health outcomes of asthmatic children with attention deficit hyperactivity disorder (ADHD) and their caregivers over a 12-month post-intervention.
Adding chemotherapy or anti-VEGF to immunotherapy is an emerging strategy to enhance the efficacy of immunotherapy in many cancers. This phase 2 study aims to explore the preliminary efficacy of combination pembrolizumab with lenvatinib and chemotherapy in NSCLC patients with sensitizing EGFR, ALK, or ROS1 genetic aberration refractory to standard targeted therapy.
This study is a prospective phase II, single arm mono-institutional study conducted in Queen Mary Hospital (Hong Kong) assessing the efficacy and safety of the sequential administration of trans-arterial chemo-embolization (TACE) and stereotactic body radiotherapy (SBRT) with immune checkpoint inhibitors in unresectable hepatocellular carcinoma (HCC) patients.
Introduction: Approximately 35% patients can not return to sports after anterior cruciate ligament reconstruction(ACLR). Persistent quadriceps weakness is a factor that prevents patients return to sports. Pre-operative quadriceps strength is a predictor for the outcomes after ACLR. Therefore, enhancing pre-operative quadriceps is important. However, current prehabilitation can not well restore quadriceps strength may be due to quadricep inhibition. Whole body vibration was proposed as a promising intervention to increase muscle strength and modulate quadriceps inhibition simultaneously. Therefore, this study aim to investigate if whole body vibration has the efficacy of enhancing pre-operative quadriceps and modulating quadricep inhibition in patients with ACL injuries. Methods: A randomized controlled trial was designed. Patients with primary ACL injuries, age from 18-45 yrs, BMI<29, physically active who awaiting ACLR will be included. Patients with any previous lower-limb injuries within 1 year, any cardiovascular or metabolic disorders will be excluded. All the subjects in this study have to finish their routine 5 week prehabilitation as well as the interventions. The primary outcomes of this study include quadriceps strength and quadriceps central activation ratio. Secondary outcomes include the score of IKDC and ACL-RSI, as well as the concentrations of myokines in serum.
This is a multi-centre phase 2 open-label prospective study designed to assess the efficacy and safety of ropeg patients with pre-fibrotic primary myelofibrosis or DIPSS low/intermediate-1 risk myelofibrosis after 24 months of treatment.
This is a prospective cohort study of children with GSD1b to evaluate their outcome after using empagliflozin for neutrophil defects.
Pneumonia is the most common infection in intensive care unit (ICU) patients and occurs in 10% of all ICU admissions. Unfortunately, ICU patient outcomes remain poor with a high mortality rate associated with pneumonia despite recent therapeutic advances. Previous studies of antibiotics used in ICU patients, which includes ceftriaxone, meropenem and piperacillin/tazobactam, have quantified major differences in pharmacokinetics (PK) between ICU and non-ICU patients, with ICU patients displaying a unique spectrum of plasma concentration-time profiles. These PK differences can lead to suboptimal antibiotic concentrations in blood, which have been associated with a reduced likelihood of clinical cure for pneumonia. Furthermore, highlighting the importance of optimised dosing for pneumonia is that multi-drug resistant (MDR) pathogens emerge during antibiotic therapy in approximately half of the ICU patients, frequently emerging from the lung. Previous work has highlighted how infection site concentrations determine patient outcome. For pneumonia, the infection site is best described as the epithelial lining fluid (ELF) in the lung. Although optimal antibiotic therapy should be considered a priority for ICU patients with pneumonia to improve the persisting poor outcomes, the dosing regimens that can achieve therapeutic concentrations at the infection site (i.e., ELF) in ICU patients with pneumonia remain unknown. The PNEUDOS study aims to address this significant knowledge gap by defining novel individualised dosing regimens that can maximise antibiotic efficacy by achieving therapeutic concentrations in the blood and ELF of ICU patients with pneumonia. These dosing regimens can then be validated in future clinical trials.
The key aim of the study is to test the efficacy of a 4-week ecological momentary intervention (EMI), as compared with the regular weekly-based intervention (control group), in reducing (1) symptoms of depression and (2) rumination in community-dwelling individuals. The efficacy of the EMI in reducing distress and improving functioning is also examined. For both EMI and control groups, the intervention will be delivered through SMS text messages, with a link to a user-friendly and locally-adapted intervention platform designed using Qualtrics (online survey programme). It is hypothesised that (1) those in the EMI group, as compared to the control group, will show greater reductions in (1) depressive symptoms, (2) rumination level, (3) distress, and in (4) improving functioning. These effects are hypothesised to be observed in individuals with varying levels of symptom severity.
This is a single-centre prospective, non-randomized trial to investigate the efficacy of cryotherapy in patients with localized prostate cancer.The aim of study is to investigate the safety profile of cryotherapy in the treatment of prostate cancer and to evaluate the oncological control of prostate cancer by means of cryotherapy focal treatment.
