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 an investigator-initiated, single-arm, exploratory clinical study.The study population consisted of treatment naive advanced esophageal squamous cell carcinoma patients. The purpose of this study was to evaluate the efficacy and safety of immunotherapy combined with chemotherapy and residual lesions irradiation of esophageal squamous cell carcinoma.
The goal of this registry-based observational study is to establish a comprehensive management plan, which focus on medical therapy, cardiac rehabilitation and active post-market surveillance of medical devices, in patients with cardiovascular diseases (CVD). Patients with CVD mainly refers to four groups of patients：1) post-percutaneous coronary intervention (post-PCI) patients; 2) patients with heart failure (HF); 3) patients with cardiometabolic diseases (CMD); 4) patients with structural heart disease (SHD), and the detailed definition of each group can be found in "Eligibility" section. The main questions this study aims to answer are: - the effectiveness of exercise-based cardiac rehabilitation in improving cardiac function, reducing CVD recurrence and mortality, and promoting quality of life for patients with CVD; - the feasibility of registry-based active post-market surveillance of high-risk medical devices used in cardiovascular surgeries, such as PCI, heart valve replacement, and cardiac resynchronization therapy (CRT); - the utilization of multiomics datasets to identify and dissect cardiovascular heterogeneity in both healthy and diseased populations and to guide precision medicine in patients with CVD; - the analysis and evaluation of the prescription patterns and drug response in patients with CVD.
This was a prospective clinical study that all voriconazole-treated adult Chinese patients with invasive pulmonary infection admitted to Zhengzhou Central Hospital affiliated to Zhengzhou University from July 2018 to June 2023. The initial voriconazole serum trough concentration, Correlation of various factors, and risk prediction factors for voriconazole serum trough concentration and hepatotoxicity were compared between elderly and non-elderly patients.
There are two parts to this trial. First, to compare the rate of myopia progression of spectacle films using Spatio Temporal Optic Phase (S.T.O.P.®) technology that provide a dynamic optical cue against single vision spectacle lenses. Second, to compare the rate of myopia progression of spectacle films using S.T.O.P.® technology that provide a dynamic optical cue against spectacle films using S.T.O.P.® technology that provide a static optical cue. A dynamic optical cue is one that changes, and a static optical cue is one that does not change.
This study aims to assess the risk factors and evaluate the long-term outcomes of patients with coronary chronic total occlusion (CTO) treated with percutaneous coronary intervention or medical treatment.
Screening for risk factors related to lung function impairment in patients who have recovered from AIDS with severe pneumonia, to provide clinical evidence for early identification and intervention of lung function damage in this population.
This is a Phase 1/2, global multicentre, open-label, single-arm, dose escalation and dose optimisation study of AZD0486 to evaluate the safety, tolerability, and efficacy of AZD0486 monotherapy in participants with R/R B ALL who have received ≥ 2 prior lines of therapies. The study will consist of 3 parts. Part A monotherapy dose escalation. Part B dose optimisation. Part C Dose expansion at the recommended phase 2 dose (RP2D)
The effect of Telitacicept treatment on the changes of transitional regulatory B lymphocyte T1, T2B cell subsets and plasma blasts and the expression levels of cytokines IL-10, IL-35, April and BAFF in SLE.
This is a single-arm, single-centre phase II study to evaluate the efficacy (PFS, ORR, DCR) and safety of recombinant human adenovirus type 5 in combination with tirelizumab and platinum-containing dual-agent chemotherapy in previously untreated patients with advanced non-small cell lung cancer who are EGFR/ALK negative. The study is divided into 2 phases.
The goal of this observational study is to test the diagnostic performance of ferumoxytol-enhanced magnetic resonance angiography/ venography（FE-MRA/MRV） on panvascular disease. The main questions it aims to answer are: 1. How about the imaging quality of FE-MRA/MRV for panvascular disease? 2. What is the diagnostic performance of FE-MRA/MRV for panvascular disease? Participants will be divided into two groups based on their symptoms, body signs or laboratory examinations. Participants who suspected with multisite atherosclerotic diseases like coronary artery disease accompany with renal artery stenosis or peripheral arterial disease will be recruited in multisite artery disease (MAD) group. While participants who suspected with venous thromboembolism (VTE) like pulmonary embolism or deep vein thrombosis will be recruited in VTE group. Participants in MAD group will take both FE-MRA and percutaneous selective angiography measurements of coronary, renal, or lower extremity artery, while participant in VTE group need to do pulmonary artery FE-MRA and computed tomography pulmonary angiography (CTPA), lower extremity vein FE-MRV and ultrasonography.
