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 prevalence of diabetes has been increasing year by year. According to the International Diabetes Federation (IDF) statistics in 2021, the global number of people with diabetes has reached 537 million. The patient population is large and heterogeneous, and precise diagnosis and treatment of diabetes patients have been a focus of attention. The objective of this study is to clarify the current status of precision classification and diagnosis of diabetes patients through retrospective and prospective cohort studies, and to establish a model for precision classification and diagnosis of diabetes, improving the accuracy of diabetes classification and diagnosis; based on big data of precision medicine for diabetes patients and follow-up cohorts, to establish precise diagnostic, therapeutic, and predictive methods for diabetes; and through multi-omics data analysis, to explore the potential pathogenesis of diabetes, explaining the heterogeneity of patients, and guiding individualized treatment for patients.
Patients with advanced biliary tract malignant tumors who had not received systematic treatment before and could not be cured were selected as the subjects of the study. The primary endpoint of the study was investigator-assessed 6-month progression-free survival (6-month PFS%) based on the RECIST v1.1 criteria, and 43 subjects were planned to be enrolled. Patients eligible for enrollment will receive Adebrelimab and a tyrosine kinase inhibitor (TKI) in combination with gemcitabine and oxaliplatin (GEMOX).
The evidence for different frequencies of rotation-traction manipulation treatment in cervical radiculopathy is insufficient. This study determined whether 3 sessions per week of rotation-traction manipulation treatment are superior to 1 session per week for symptomatic outcomes in cervical radiculopathy based on a multicenter randomized controlled trial.
TQB2223 is a recombinant, fully human antibody that binds to lymphocyte activation gene-3 (LAG-3) and blocks the LAG-3/ major histocompatibility complex class II (MHC-II) interaction, thus allowing for increased T-cell proliferation and cytokine production. This is a phase Ib study aimed at evaluating the safety, tolerability, and immunogenicity characteristics of TQB2223 injection combined with AK105 injection in the treatment of advanced hepatocellular carcinoma.
The CHANCE-4 study is a multicenter, double-blind, double-simulation, randomized controlled study. In patients at high-risk for mild ischemic stroke or transient ischemic attack with symptomatic intracranial artery stenosis within 24 hours of onset, we will examine whether treatment with tirofiban for 48 hours reduce the risk of ischemic stroke recurrence within 90 days compared with placebo.
Extracorporeal membrane pulmonary oxygenation (ECMO) may provide partial or complete support for organ replacement in patients with severe cardiopulmonary failure, buying time for further management of the primary disease. However, ECMO may significantly alter the pharmacokinetic and pharmacodynamic profiles of critically ill patients, affecting the safety and efficacy of drug therapy. This prospective observational study aims to investigate the impact of ECMO treatment on the pharmacokinetics and pharmacodynamics of antimicrobial drugs in critically ill adult patients. Investigators intend to establish a Population Pharmacokinetic (POP PK) and Pharmacokinetic/Pharmacodynamic (PK/PD) model by prospectively collecting blood samples from patients and relevant treatment data. The primary objective is to quantitatively characterize the pharmacokinetic profiles of critically ill patients undergoing ECMO support and provide model-based recommendations for drug regimens tailored to critically ill patients.
Petroclival meningioma (PCM) is a technically challenging lesion. We aimed to analyze the role of various skull base approaches and evaluate the therapeutic outcomes guided by the modified classification. We retrospectively analyzed the clinical characteristics, surgical approaches, outcomes and follow-up data from 179 cases of PCM from January 2011 to December 2020. We modified the previous classification into updated five types with two subtypes: clivus type (CV), petroclival type (PC), petroclivosphenoidal type (PC-S), sphenopetroclival type (S-PC) with two subtypes of S-PC I and S-PC II and central skull base type (CSB). Statistical analysis was performed using IBM SPSS Statistical Package 21.0. The t-test was performed to clinical data comparisons between the two groups and the ANOVA test was used to compare the difference between multiple groups. P < 0.05 was considered statistically significant.
This is a global, multicenter, randomized, open-label, Phase III confirmatory study to investigate the efficacy and safety of Lisaftoclax (APG-2575) in combination with Acalabrutinib in patients with newly diagnosed CLL/SLL.
Tacrolimus is the most commonly used immunosuppressant for preventing and treating rejection after liver transplantation. However, its treatment window is narrow, the pharmacokinetic individual differences are large, routine dose according to body weight, sometimes low dose will cause graft rejection of patients, or high dose will lead to infection and liver and kidney toxicity and other adverse reactions. Moreover, the conventional drug testing can not fully reflect the efficacy of tacrolimus, and there are shortcomings of lag, experience and passivity. FK506 is metabolized primarily by cytochrome P450 member 3A5 in the liver and intestines. CYP3A5*3 is the most important factor determining the expression level of CYP3A5. This mutation can cause variable shear and produce unstable protein, so that patients carrying CYP3A5*3/*3 gene do not express CYP3A5. Acute kidney injury is a common and important complication after liver transplantation. Despite recent advances in organ preservation, surgical techniques, and immunosuppressive protocols, the incidence of AKI after orthotopic liver transplantation remains high. AKI has a significant impact on both short - and long-term prognosis of orthotopic liver transplantation recipients. Studies have shown that orthotopic liver transplantation recipients with AKI have significantly higher mortality rates in hospital, at 28 days and at 1 year after surgery than those without AKI. In this study, the relationship between donor and recipient CYP3A5 gene polymorphism and tacrolimus concentration was investigated, and the effect of donor and recipient CYP3A5 gene polymorphism and tacrolimus concentration on acute kidney injury after liver transplantation was investigated. To provide guidance for individual administration of gene-directed tacrolimus in patients, and provide basis for prevention and reduction of postoperative acute kidney injury in liver transplantation patients.
This is a pilot exploratory observational prospective cohort phase I study. In this study, we will gather preliminary data to evaluate (i) the magnitude of changes in blood flow in the bowel before and after feeding and (ii) the differences between preterm and term infants.
