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.
Helicobacter pylori (H. pylori) infection is a common global infectious disease of the gastrointestinal tract. Helicobacter pylori eradication can effectively prevent the development of gastric cancer.The researchers collect H.pylori-positive patients who need native therapy. The subjects were randomized to receive7 days and 14 days of bismuth quadruple eradication therapy. 6-8 weeks after treatment, the subjects will re-take the 13C-urea breath test. Calculate the eradication rates, adverse reaction rates and patient compliance of each group.
This is a study to evaluate the maximum tolerated dose (MTD), occurrence of all adverse events (AEs) and serious adverse events (SAEs), pharmacokinetic parameters and antitumor effect of TQB3912 tablets in Chinese adult patients with advanced malignant neoplasm. The study was divided into phase Ia and phase Ib, Phase Ia: Dose escalation period, to evaluate the safety and tolerability of TQB3912 tablets, determine MTD; Phase Ib: Effectiveness exploration period, to expand the safe and effective dose group, and to recommend appropriate dosage and method for subsequent clinical research.
To evaluate the efficacy and safety of different doses of triamcinolone for local infiltration analgesia during total knee replacement
Oral lichen planus (OLP) is a common chronic inflammatory disease of Oral mucosa. The pathogenesis of OLP is not clear, and there is no effective method to cure it. In vitro, previous studies have shown that oral mucosal mesenchymal stem cell cells (MSCs) can secrete Ido, which is involved in the pathogenesis of OLP. It has been proved that mental disorders such as depression and anxiety play an important role in the pathogenesis and treatment of OLP. Mental stress factors can cause abnormal changes of inflammatory factors, leading to immune dysfunction, which is also one of the main causes of OLP. In this study, we integrated the advantages of stomatology, psychiatry, neurobiology and traditional Chinese medicine, focused on the clinical problems of mental disorders with oral mucosal comorbidity, and assessed the depressive and anxiety status of OLP patients, so as to improve the therapeutic effect of OLP.
Importance: Lymphovascular invasion (LVI) is a poor prognosis pathologic feature in pancreatic ductal adenocarcinoma (PDAC) patients. Neoadjuvant therapy may bring survival benefits to these patients. Objective: To construct a preoperative model which could predict LVI in PDAC patients and further validate it in other cohorts. Design, Setting, and Participants: Patients from 3 three tertiary hospitals were included in this study. Univariate and multivariate Logistic regression analyses were conducted to define independent prediction factors of LVI. A nomogram was constructed based on the result of multivariate analysis.The predictive value of the model was assessed using receiver operating characteristic (ROC) curves and the maximum Youden index of the ROC curve was defined as the cut-off point. The calibration plot was utilized to assess the concordance of the model. The decision curve analyses (DCA) were applied to estimate the clinical benefit of using this model to predict LVI.
A randomized controlled trial is to be conducted to confirm the efficacy and safety of intramuscular injection of botulinum toxin in the treatment of Parkinson's bladder overactivity.
To observe the safety and efficacy of intensive drug therapy for ischemic stroke caused by severe intracranial arterial stenosis.Patients with acute stroke caused by intracranial arterial stenosis (stenosis rate ≥70%) were enrolled and accept dual antiplatelet therapy (DAPT) (aspirin 100 mg/d and clopidogrel 75 mg/d for 90 days, followed by aspirin 100 mg/d for long term) under the guidance of platelet function analysis (Verifynow) combined with the intensive statin therapy (40 mg/d for 14 days, followed by 20 mg/d for long term).
This study will evaluate the efficacy and safety of intravenous RC48-ADC in adjuvant/salvage treatment of HER2 positive high-risk non-muscle-invasive bladder cancer.
This study will look at how well the new medicine CagriSema helps people with excess body weight losing weight compared to a "dummy" medicine and a medicine called semaglutide. Participants will either get CagriSema, a dummy medicine or semaglutide. Which treatment participants get is decided by chance. Participants will take one injection once a week. The study medicine will be injected briefly with a thin needle, typically in the stomach, thighs or upper arms. The study will last for about 1 year.
In the recently published multi-center, prospective, single-blind study (THUNDER study), using the methylation signal in cfDNA isolated from the peripheral blood to detect the six types of cancer, the sensitivity for liver cancer detection achieved 87.8%, with a specificity of 98.9%. In this study, a multicenter, case-control study is designed to establish an early cancer detection model based on cfDNA methylation biomarkers using qPCR to detect primary liver cancer and further validate the performance of the model.
