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 Phase 1b clinical study is a multi-center, open-label, dose escalation, prime only, and prime plus boost therapeutic vaccination study of 2 distinct chimpanzee adenoviral vectors (AdC6 and AdC7), containing parts of hepatitis B virus (HBV) core and polymerase antigens fused within glycoprotein D in a cohort of chronic hepatitis B (CHB)-infected adult participants who are currently receiving entecavir, tenofovir (tenofovir alafenamide fumarate or tenofovir disoproxil fumarate), or lamivudine, with documented HBV viral load suppression for at least 12 months. Approximately 24 participants will be enrolled in Group 1 and randomized to Cohort 1a or Cohort 1b. Those assigned to Cohort 1a will receive a low dose prime therapeutic vaccination of vector AdC7 on Day 1, followed by a booster vaccination on Day 91 using vector AdC6. Those assigned to Cohort 1b will receive a low dose prime therapeutic vaccination of vector AdC6 on Day 1, and will not receive a booster vaccination. Group 2 will then enroll approximately 24 participants randomized to Cohort 2a or Cohort 2b. Those assigned to Cohort 2a will receive a high dose prime therapeutic vaccination of vector AdC7 on Day 1, followed by a booster vaccination on Day 91 using vector AdC6. Those assigned to Cohort 2b will receive a high dose prime therapeutic vaccination of vector AdC6 on Day 1, and will not receive a booster vaccination. All vaccine doses will be administered by intramuscular (IM) injection. All study participants will be followed for a total of 1 year post-prime vaccination.
IgE-mediated wheat allergy is a growing allergy problem in children, and affected children can predict with immediate-type allergic reactions to the extent of anaphylactic shock. Current diagnostic methods based on crude wheat extract are inaccurate and unreliable. Besides, these children are managed by a passive "wait-and-see" approach that reflect the natural history of wheat allergy. Nonetheless, a significant proportion of wheat-allergic children have persistent disease until school-age and adolescence. There is an unmet need for designing effective and safe immunotherapeutic strategy for wheat allergy. This study aims to investigate performance of allergy tests based on crude wheat and wheat allergens as measured using both quantitative and functional IgE-based assays for diagnosing IgE-mediated wheat allergy; and to compare efficacy and safety of different dosages of wheat oral immunotherapy (OIT) for treating these paediatric patients. For the initial part, this study will recruit children with immediate-onset adverse reactions after wheat ingestion for different allergy tests, with their wheat allergy ascertained by the gold-standard double-blind, placebo-controlled food challenge. The investigators will then recruit the wheat-allergic children into a randomized, double-blind, parallel-group clinical trial with low-dose and standard-dose wheat OIT for 12 months. The main outcomes include the diagnostic performance of different conventional and novel allergy tests for challenge-confirmed wheat allergy and the rates of desensitization and sustained unresponsiveness achieved by the two dosing regimens of wheat OIT.
This is a Phase III, randomized, open-label multicenter study that will evaluate the efficacy and safety of giredestrant compared with fulvestrant, both in combination with the investigator's choice of a CDK4/6 inhibitor (palbociclib, ribociclib or abemaciclib), in participants with estrogen receptor-positive (ER+), human epidermal growth factor receptor 2-negative (HER2-) advanced breast cancer who have developed resistance to adjuvant endocrine therapy.
The goal of this observational study is to determine the utility of desmosine, D-dimer and aggrecan as early diagnostic biomarkers in aortic dissection. The main questions it aims to answer are: - To investigate the plasma levels of selected biomarkers in ED patients with confirmed aortic dissection - To study the diagnostic performance of plasma levels of selected biomarkers for aortic dissection - To study the association between plasma levels of selected biomarkers and clinical outcomes
The goal of this observational study is to assess the correlation between the artificial intelligence (AI) derived effective withdrawal time (EWT) during colonoscopy and endoscopists' baseline adenoma detection rate (ADR). The association between the AI derived EWT with ADR during the prospective colonoscopy series would also be determined. The colonoscopy video of participants will be monitored by the AI and the result of EWT will be blinded to the endoscopists
The research purpose is to investigate the feasibility of using a motor-cable-driven system for wrist and forearm recovery of hemiplegic subjects suffered from stroke, where assistive force would be generated from cables connected to pulleys and electrical motors. The system may use EMG signal to control the movements.
Colonoscopic removal of adenomatous polyps reduce both the incidence and mortality of colorectal cancer (CRC). The common clinical management of colorectal polyp detected during colonoscopy is to remove them and send for histopathology to determine the subsequent surveillance interval. More than 80% of polyps detected during screening or surveillance colonoscopy are diminutive (≤5mm). As the chance of diminutive polyps to harbor cancer or advanced neoplasia is low, leave-in-situ and resect-and-discard strategies using optical diagnosis are recommended for non-neoplastic polyps by the American Society for Gastrointestinal Endoscopy (ASGE) and the European Society for Gastrointestinal Endoscopy (ESGE) so as to reduce the financial burden of polypectomy and histopathology. The societies proposed leave-in-situ strategy if optical diagnosis can achieve a negative predictive value (NPV) of >90% for rectosigmoid polyp and resect-and-discard if an agreement of more than 90% concordance with histopathology-based post-polypectomy surveillance interval can be achieved. However, optical diagnosis is operator dependent and most endoscopists are reluctant to adopt this strategy in routine practice because of the need of strict training and auditing and fear of incorrect diagnosis. In the past decade, with the exponential increase in computational power, reduced cost of data storage, improved algorithmic sophistication, and increased availability of electronic health data, artificial intelligence (AI) assisted technologies were widely adopted in various healthcare settings to improve clinical outcomes, especially the quality of colonoscopy in the area of gastroenterology. Real time use of computer-aided diagnosis (CADx) for adenoma using AI systems were developed and proven to be useful to help endoscopists to distinguish neoplastic polyps from non-adenomatous polyps. However, these studies only examined diminutive polyp but not polyp of larger size (>5mm). They were conducted with small sample size of less than few hundred subjects and the study settings were open-label and non-randomized. The investigators aim to conduct a large scale randomized controlled trial to evaluate the performance of colorectal polyp characterization of all size polyps by real-time CADx using AI system against conventional colonoscopy with optical diagnosis.
The goal of this randomised controlled trial is to test the effectiveness of a mobile instant messaging-based lifestyle intervention in pregnant women at risk of gestational diabetes
This study will evaluate the feasibility of performing robotic navigation of peripheral airways in human subjects for the purpose of biopsying peripheral lung lesions.
The combination of neoadjuvant immunotherapy plus chemotherapy has recently been shown to improve survival outcome compared to chemotherapy alone and was recently approved for resectable non-small cell lung cancer (NSCLC). Despite so, recurrence risk of NSCLC after surgical resection remains high. Sacituzumab govitecan, a novel antibody drug conjugate, was demonstrated to be clinically active in metastatic NSCLC. This study aims to study the clinical efficacy of sacituzumab govitecan plus immunotherapy in resectable NSCLC. This is a open-label, single arm, multicentre, phase II study. Patients with EGFR/ALK negative, stage II-III (AJCC 8th edition), resectable NSCLC are eligible and will receive 4 cycles of neoadjuvant pembrolizumab plus sacituzumab govitecan, followed by surgical resection of tumour, and then 13 cycles of maintenance pembrolizumab.
