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 study aims to explore the effectiveness of tranexamic acid (also known as trans amine or TXA) in reducing hematoma expansion in patients with hemorrhagic stroke when given in the acute phase. METHODOLOGY This will be a Phase III, parallel-group double-blind randomised placebo control trial. Patients allocated to the control group will receive standard care for hemorrhagic stroke according to the 2015 American Heart Association guidelines. Patients allocated to the intervention group will receive, in addition to standard care, a loading dose of intravenous TXA 1gm within 3 hours of symptom onset followed by a 1gm maintenance dose over 8 hours. Timing and dosing are in accordance to previous established study protocols. Patients in the intervention group will only receive a single treatment course of TXA. Study subjects will be identified by either the on-duty clinicians from the Department of Neurosurgery of this institution or by the study investigators. Should the patient meet study eligibility criteria consent will be obtained either from the patient or from his/her next of kin. 1:1 block randomization will be performed by a remote internet randomization service by accessing a website. Patients allocated to the intervention arm will have 1gm of TXA added to 100ml of normal saline (0.9%) infused over 10 minutes as a loading dose. This is then followed by a maintenance dose of 1gm of TXA in 500ml of intravenous isotonic solution infused at 120mg/hour (60ml/hour) for 8 hours. Patient's allocated to the control arm will have an equal volume of normal saline (0.9%) infused as a placebo. The patient and the outcome assessor will be blinded to study group allocation. The primary endpoint of this study will be to assess the percentage change in brain blood clot volume by computed tomography brain scans on admission, 6 hours later, at 24 hours and at 1 week.
To investigate whether an oral nutritional supplement of a mixture of arginine, glutamine and HMB for a maximum period of four weeks is more beneficial than the standard dietary approach to the healing of pressure ulcers, and to examine whether the use of it can reduce admissions and length of hospitalizations for these patients.
The purpose of the present study is to examine the effects of perspective-taking reappraisals on the well-being of adult-child dementia caregivers.
Conventional chemotherapeutic regimens designed for aggressive B-cell lymphomas are generally less effective when applied to mature T-cell or NK-cell lymphomas. The treatment outcome for relapsed or refractory disease is especially poor. This is a single centre, prospective, non-randomized, open-label, phase II study to evaluate the efficacy of pembrolizumab in patients with relapsed or refractory mature T-cell or NK-cell lymphomas. Patients will receive pembrolizumab 200mg i.v. once every 3 weeks until disease progression or unacceptable toxicity. A baseline radiological assessment by positron emission tomography / computed tomography (PET/CT) scan is obtained before commencement of treatment. Tumor response and progression are evaluated by physical examination, standard laboratory tests, and PET/CT scan according to standard criteria. Standard response criteria for non-Hodgkin lymphomas are used for assessment . PET/CT scan will be done at week 12, week 24, week 36 and every 18 weeks thereafter.
This randomized phase III trial studies how well imatinib mesylate works in combination with two different chemotherapy regimens in treating patients with newly diagnosed Philadelphia chromosome positive acute lymphoblastic leukemia (ALL). Imatinib mesylate has been shown to improve outcomes in children and adolescents with Philadelphia chromosome positive (Ph+) ALL when given with strong chemotherapy, but the combination has many side effects. This trial is testing whether a different chemotherapy regimen may work as well as the stronger one but have fewer side effects when given with imatinib. The trial is also testing how well the combination of chemotherapy and imatinib works in another group of patients with a type of ALL that is similar to Ph+ ALL. This type of ALL is called "ABL-class fusion positive ALL", and because it is similar to Ph+ ALL, is thought it will respond well to the combination of agents used to treat Ph+ ALL.
The purpose of this study is to compare the effects of qigong practice with fitness exercise on balance, fall-efficacy, physical functions, psychological wellbeing and quality of life of stroke survivors.
Efficacy and Safety of ibrutinib in patients with chronic lymphocytic leukemia and other indolent B-cell lymphomas who are chronic hepatitis B virus carriers or occult hepatitis B virus carriers

The purpose of this study is to collect long term safety data in subjects who are continuing to derive clinical benefit from treatment with Enzalutamide from the subjects participation in an enzalutamide clinical study sponsored by Astellas or Medivation (i.e., parent study) which has completed, at a minimum, the primary analysis or the study specified evaluation period.
High definition tDCS will be conducted to both stroke and healthy subjects on primary motor cortex area to explore the motor excitability changes before and after stimulation. In next stage, a randomized control trial with 20-session training will be conducted to evaluate the effectiveness of transient modulation of cortical excitability through multisite HD-tDCS with EMG driven robot hand training, a sham stimulation with EMG-driven robot hand training will be applied as control group.
