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 aim of this observational study is to comprehensively analyze the metabolites in plasma samples from multi-cancer patients using advanced mass spectrometry detection technology, in conjunction with metabolomics approaches. The goal is to construct a plasma metabolite database for multi-cancer patients. Simultaneously, we will delve into the exploration and validation of a series of metabolic biomarkers for early multi-cancer diagnosis. The objective is to establish a safer, more convenient, and more sensitive early screening method, thereby providing a reliable scientific foundation and critical evidence for improving the early diagnostic process for individuals at high risk of multi-cancer.
The goal of this clinical trial is to evaluate the efficacy and safety of cardonilizumab injection combined with TKI in second-line treatment of advanced hepatocellular carcinoma. The main questions it aims to answer are: - Objective response rate (ORR) for evaluation - Disease Control Rate (DCR); Duration of relief (DoR); Progression free survival (PFS); Total survival time (OS); Safety。
The purpose of this study is to investigate the preliminary surgical outcomes of laparoscopic right hemicolectomy with transrectal specimen extraction. The hypothesis is that this type of natural orifice specimen extraction surgery (NOSES) could achieve good short-term and oncological outcomes for right colon cancer patients.
The purpose of this study is to evaluate a cognitive-motor exercise on dual-task interference during dual-task ankle movement and the corresponding alterations of brain activity.
1. Integrate pharmacokinetic-pharmacodynamic (PK-PD) modeling and pharmacogenomics techniques to develop a population PK-PD model, aiming to explore monitoring and dose guidance schemes for Direct Oral Anticoagulants (DOACs). 2. Investigate the factors influencing PK-PD of DOACs in the pulmonary embolism population, clarifying the correlation between genotype characteristics and clinical outcomes. 3. Explore the correlation between drug concentrations, coagulation indices, and clinical outcomes of DOACs, defining the indications for DOACs testing and the overall monitoring process.
Accurate preoperative detection of muscle-invasive bladder cancer remains a clinical challenge. The investigators aimed to develop and validate a knowledge-guided causal diagnostic network for the detection of muscle-invasive bladder cancer with multiparametric magnetic resonance imaging(MRI).
Explore the impact of the first-line application of Toripalimab with or without Lenvatinib or chemotherapy, on the survival, disease progression, and drug safety of patients with advanced biliary tract cancers
The goal of this clinical trial is to compare the cancer detection rates of MRI artificial intelligence-guided cTB (AI-cTB) and routine cTB, and explore the added value of using AI for the guidance of cTB. The main questions it aims to answer are: Does AI-cTB promote the accurate diagnosis and treatment of prostate cancer? What's the value of prostate MRI artificial intelligence assistant diagnosis system in developing the best scheme of prostate biopsy? What's the value of prostate MRI artificial intelligence assistant diagnosis system in predicting the pathological results of prostate targeted biopsy? Researchers will compare the cancer detection rates of AI-cTB and routine cTB to explore the added value of using AI for the guidance of cTB. Participants will: Receive AI-cTB or routine cTB.
The goal of this multi-center observational clinical trial is to investigate the genetic risk factors of patients with premature CAD and none traditional CAD risk factors through a multi-omics approach. The main questions it aims to answer are: - Genetic risk factors & metabolic fingerprints of patients with premature CAD and none traditional CAD risk factors remain unknown. - How to optimize current primary prevention strategy for this rare CAD subgroup？
This study includes two cohorts, cohort A is for non-squamous NSCLC and cohort B is for squamous NSCLC.
