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.
Pain is the main complication after TACE(Transcatheter Arterial Chemoembolization) for hepatocellular carcinoma, and its pathogenesis is not clear.The pain may be related to partial liver tissue swelling after blocking the tumor blood supply artery embolization agent, transient hepatic swelling causing tension or strain on the liver capsule, and chemical irritation by the anticancer drug-Lipiodol mixture,the inadvertent embolization of normal organs and individual sensitivity to pain. Ketamine produces anesthetic and analgesic effects mainly by inhibiting NMDA receptor(N-methyl-D-aspartic acid receptor), and previous studies have shown that low concentrations of ketamine have obvious analgesic effects. Not only that, ketamine also produces analgesic effects by inhibiting opioid receptors via G-protein coupling. In addition, ketamine can bind to monoaminergic receptors in the central and peripheral nervous system, showing an anticholinergic effect and producing an antispasmodic effect. Ketamine also inhibits inflammatory pain by reducing nitric oxide production by inhibiting nitric oxide synthase. Esketamine is about three to four times more potent than ketamine. Therefore,esketamine requires a lower dose, about half the dose of ketamine, to produce anesthetic and analgesic effects, with fewer side effects.
This project is expected to screen reliable serum markers in pregnant women with gestational diabetes mellitus (GDM) by using metabolic profiling and lipid profiling clinical high-throughput mass spectrometry technology. We intend to build an early pregnancy prediction model for postpartum glucose metabolism abnormalities of GDM. At the same time, this project plans to develop a predictive management system based on this model, so that it can be widely used in clinical detection process, realize the advance of the early warning window period of abnormal glucose metabolism, and provide theoretical guidance for the early postpartum blocking of GDM to the outcome of abnormal glucose metabolism.
The purpose of this study was to analyze the relationship between the microbial community, host immunity and the prognosis of patients with severe COVID-19.
In order to assessment the safety and efficacy of debulking atherectomy versus stent angioplasty for limb ischaemia of diabetic lower limb atherosclerosis-occlusive disease, we intend to conduct a prospective, multicenter, randomized controlled, non-inferiority trial. The main surgical methods included stent angioplasty group (Nickel-titanium self-expanding bare stent) and debulking atherectomy group (Excimer laser atherectomy combined with drug-coated balloon angioplasty). The sample size was 244 patients, and the patients were followed up at 30 days, 180 days, and 365 days after operation.
The purpose of this study is to assess the efficacy, safety, tolerability, Pharmacokinetic(s) (PK) and dosimetry of [177Lu]Lu-PSMA-617 when administered in addition to Best Supportive/Best Standard of Care (BSC/BSoC) in Chinese participants with progressive PSMA-positive mCRPC who received at least 1 novel androgen receptor pathway inhibitor (ARPI) and were previously treated with 1 to 2 taxane regimens. Furthermore, the safety, PK, and dosimetry of [68Ga]Ga-PSMA-11 are assessed. Data from this study will be used to bridge global pivotal phase III study (VISION, AAA617A12301) and to support China registration of [177Lu]Lu-PSMA-617 as a novel anticancer modality, namely radioligand therapy, in mCRPC.
- This is a multi-center, open-label, Phase 2 treatment extension study in participants with multiple myeloma who are still benefitting from isatuximab based therapy following completion of a Phase 1, 2, or 3 parental study. - This Treatment Extension study has the purpose to provide continued access to isatuximab. Adult participants with multiple myeloma who have enrolled on an isatuximab parental study for which study objectives are completed will be eligible to be enrolled in this Treatment Extension study. - The primary objective of the study is to assess long-term safety of isatuximab as study treatment.
The goal of this phase II single arm prospective clinical study is to evaluate the efficacy and toxicity of pamiparib + tamoxifen regimen in epithelial ovarian cancer patients with biochemical recurrence during first-line PARPi maintenance therapy. The main questions it aims to answer are: - Effect of the regimen on the reduction of CA125 - The delayed effect of treatment regimens on the patient's radiographic progression
Hepatic encephalopathy (HE) is one of the most serious complications of end-stage liver disease and an independent predictor of death in patients with liver cirrhosis. Recurrent hepatic encephalopathy is defined as recurrent hepatic encephalopathy after rifaximin combined with lactulose treatment. This project designs a prospective, multicenter cohort study on the treatment of recurrent hepatic encephalopathy with fecal microbiota transplantation, carries out the comparison of fecal microbiota transplantation with different amounts of bacteria, and the dynamic sequencing of the macro genome of the recipient's stool, compares the effectiveness and safety of fecal microbiota transplantation with different amounts of bacteria in the treatment of recurrent hepatic encephalopathy, and explores the internal mechanism of different effects, providing a new idea for the treatment of recurrent HE in clinical practice.
The goal of this observational study is to learn about in the development process of adverse reactions of anti-PD1 immunotherapy. The main question it aims to observe: - The autoantibody profile of patients - The adverse reactions of patients - The changes of immune cells and cytokine in patients
The goal of this clinical trial is to evaluate the efficacy, safety and immunogenicity of a live attenuated varicella vaccine manufactured by Beijing Institute of Biological Products Co., Ltd in healthy children.
