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.
This is a multi-center, randomized, double blind, placebo-controlled study to evaluate the efficacy, safety, tolerance, pharmacokinetics, pharmacodynamics, and immunogenicity of CM326 in moderate-severe atopic dermatitis subjects.
Due to lacking of evidence on surveillance for gastric neuroendocrine carcinoma (G-NEC), this study aimed to determine the optimal postsurgical surveillance strategy for G-NEC patients and compare its cost-effectiveness with traditional surveillance strategies.
About 60% of patients with hypertrophic cardiomyopathy have microvascular dysfunction. Microvascular dysfunction is directly related to prognosis in hypertrophic cardiomyopathy. This new measurement method is microcirculation resistance (MR) based on quantitative flow ratio (QFR), which does not need a pressure guide wire on the basis of angiography. The QFR system is used to evaluate the blood vessels distal pressure and blood flow, and their ratio is microcirculation resistance (MR). The quantitative blood flow fraction measurement system was analyzed by interventional laboratory platform image analysis software (AngioPlus 2.0). This study is a single-center retrospective cohort study. Participants were selected from patients who were diagnosed with hypertrophic obstructive cardiomyopathy in Fuwai Hospital from January 2020 to November 2021. The risk factor is whether there is microcirculation resistance disorder. The outcome was the major adverse cardiovascular events related to HCM (including all-cause death, heart transplantation, left ventricular pacemaker, and heart failure readmission) that were followed up one year after angiography. Aim To further clarify whether there is a certain correlation between microvascular resistance and adverse cardiovascular prognosis.
China's new cases and deaths of hepatocellular carcinoma (HCC) rank first in the world. hepatocellular carcinoma is the third most morbid, second-most mortal malignancy in China. Up to 80% of hepatocellular carcinoma patients caused by HBV infection. Antiviral therapy can significantly reduce the incidence and mortality of hepatocellular carcinoma in patients with chronic hepatitis B (CHB), hinder the progression of liver disease, and effectively control the disease. However, studies in recent years have found that long-term therapy with Nucleos(t)ide analogue (NAs) cannot completely eliminate the risk of liver cancer in patients with chronic hepatitis B. In addition, a number of retrospective studies at home and abroad have shown that compared with long-term oral NAs, peginterferon can significantly reduce the risk of hepatocellular carcinoma in patients with chronic hepatitis B. However, there is limit prospective studies. This multicenter, randomized, open-label, controlled trial study is aim to evaluate the pegylated interferon alfa-2b injection in comparing to NAs in reducing the incidence of hepatocellular carcinoma, to provide evidences for new management and treatment strategy options for improving clinical outcomes for the chronic hepatitis B patients. About 267 chronic hepatitis patients with intermediate to high risk of liver cancer who are now receiving nucleoside therapy will be enrolled. Subjects will be randomized into the peginterferon combined NAs group and the NAs monotherapy group at a ratio of 2:1. Level of HBsAg, proportion of patients with HBsAg clearance and seroconversion, incidence of liver cirrhosis and hepatocellular carcinoma will be assessed.
The goal of this study to investigate the volatile organic compounds (VOCs) in the urine samples of both healthy individual and bladder cancer patients, using gas chromatography - mass spectrometry. Researchers aim to find a set of certain VOCs specific to bladder cancer and use this set to construct a diagnostic model that can help diagnosing bladder cancer. Participants will be asked to collect their early morning midstream urine in a predesignated container. Researchers will compare urine VOCs from bladder cancer patients and healthy individuals to see if there is any VOC whose concentration differ significantly among the two groups.
The primary objective of this investigation is to compare the efficacy of two different antithrombotic strategies after percutaneous LAA occlusion with a Watchman device on the prevention of silent cerebral embolism.
The goal of this clinical trial is to study the efficacy of collagen supplement on the moisture content and elasticity. 70 participants of 30-50 years old women will be enrolled from two study sites and randomly assigned to use two products (study product plus collagen supplement and placebo product without collagen supplement) for 2 months. Researchers will compare the two groups to validate the assumption that there is significant improvement on skin anti-aging effect for participants using study product plus collagen supplement.
The study is being conducted to evaluate the Opportune Administration of Nab-paclitaxel in the First Line Treatment Strategy, Camrelizumab and Famitinib with/without Nab-paclitaxel, of Patients with Unresectable Locally Advanced or Metastatic Immunomodulatory Triple Negative Breast Cancer.
In clinical trials of preclinical pharmacodynamic studies, Wei Li Bai capsules has been proved to significantly improve the learning and memory ability of Alzheimer's disease model. In this study, the researchers will use a multicenter, randomized, double-blind, placebo-controlled parallel method to recruit Alzheimer's disease patients to confirm the efficacy and safety of Wei Li Bai capsules. Confirmation of drug efficacy will be observed through changes in Alzheimer's disease patients' general cognitive function scores, scores of different cognitive domains, daily living activities, and symptom severities.
The goal of this observational study is to compare the incidence of ARI and/or diarrheal disease associated with feeding different formulas with and without lactoferrin supplement in children of 2-3 years old. 200 children eligible for the study will be enrolled from two study sites and randomly assigned to two groups (a2 growing up stage 3 formula puls lactoferrin supplement, and Enfinitas growing up stage 3 formula) to feed for 90 days. About 160 children (80 for each group) are expected to finish the study, and data will be collected during the four visits across the study. Researchers will compare the two groups to see if there is significant decrease of the occurrence of diarrheal disease and/or acute respiratory infection for children fed with a2 growing up stage 3 formula puls lactoferrin supplement
