There are about 36818 clinical studies being (or have been) conducted in China. 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.
The study was designed to evaluate the pharmacokinetic effects of itraconazole and rifampicin on HRS-1780 after oral administration of HRS-1780 tablets in healthy subjects
In terms of the diagnostic technology of brain neurodegenerative diseases, the injection of positron tracers into the human body, so that it can combine with the corresponding protein, and show its distribution through PET imaging is a mature technology in the industry. At present, several research groups around the world are working on the development and clinical efficacy evaluation of their respective tau imaging agent compounds.This clinical research project intends to display the abnormal changes of tau protein in living brain through [18F]PM-PBB3 PET imaging, which is a second-generation tracer further optimized on the basis of [11C]PBB3, and has the advantages of closer binding to tau protein entanglement and less non-specific binding than similar imaging agents. Better image quality and a wider range of clinical applications.
A multi-center, real world study to evaluate the clinical outcomes between initial CDK 4/6 Inhibitor plus endocrine therapy and initial chemotherapy in HR positive, HER2 negative unresectable or metastatic breast cancer.
A multi-center, real world study to evaluate the clinical outcomes and safety of Abemaciclib, Palbociclib or Dalpiciclib combined with endocrine therapy as first-line treatment in HR Positive, HER2 Negative unresectable or metastatic Breast Cancer.
To investigate the treatment pattern and efficacy of patients with negative primary ER lesion but positive ER expression in MBC using a novel convenient way of 18F-fluoroestradiol positron emission tomography/computed tomography (18F-FES PET/CT).
The main purpose of this study is to verify and compare the treatment effects of scarred ectropion surgery, perform statistical descriptions, compare patients undergoing tarsal strip and skin flap procedures with those undergoing simple skin flap treatment, and compare their pre- and post-operative Ectropion Grading Scale (EGS) and subjective and objective symptom changes. Secondary Objective: To observe the incidence and resolution of complications after lower eyelid ectropion surgery. Compare postoperative effects among patients of different ages undergoing the same surgery.
To Evaluate the Safety, Tolerability, and Pharmacokinetic Characteristics of JMKX003142 Injection Administered Randomly, Double-blind, Placebo-controlled, Single-ascending Dose and Multiple-ascending Doses in Chinese Healthy Adult Subjects
The INTELICE trial is a prospective, multicenter, 1:1 randomized controlled non-inferiority study. It aims to compare a novel intracardiac echography (ICE) catheter and combined ultrasound system with existing commercial ones. The evaluation will be conducted on patients undergoing planned intracardiac interventional process.
Herpes zoster (HZ) is a skin infection disease which cause severe zoster-associated pain (ZAP) along sensory nerve in the corresponding segment. Evidence for the efficacy of existing local therapies for acute/subacute ZAP is limited. The hypothesis is that patients with acute/subacute ZAP treated with TPIs with local anesthetic and steroids under the basis of standard treatment will show better clinical outcomes compared with subjects treated with standard antiviral medicine treatment only.
Pentoxifylline can improve cognitive impairment after ischemic stroke, possibly by improving the level of cerebral blood flow, affecting the content of blood oxygen and metabolic substances in the brain, and then playing a protective role in the transmission of nerve electrical signals, and ultimately improving cognitive function. The patients with cognitive impairment and non-dementia PSCIND after ischemic stroke were randomly divided into two groups. In addition to the basic drugs of ischemic stroke, the patients were given pentothemine sustained release tablets and blank control respectively to observe the effects of pentothemine on cognitive function and neuronal electrical signals in the patients with ischemic PSCIND. It is expected to explore the possible internal biological mechanism by using transcranial Doppler, oxygen-dependent functional magnetic resonance imaging and craniocerebral magnetic resonance pop analysis. Finally, statistical correlation analysis was used to elucidate the specific mechanism of pentoxifylline in improving cognitive function of non-dementia patients with cognitive impairment after ischemic stroke.
