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.
Although emerging evidence demonstrated that left bundle branch pacing (LBBP) is a promising alternative for patients with either a bradycardia or a heart failure pacing indication. However, a direct comparison of the safety, efficacy and LV systolic synchrony between LBBP and RVP regimens was rare. In this study, the investigators aim to conduct a comparison of the safety and effectiveness performance between these two pacing methods for patients with atrioventricular block (AVB). The investigators focused on AVB patients undergoing permanent pacemaker implantations from the 1st of January 2018 to the 18th of November 2021 at West China Hospital.
Peritoneal metastasis of gastric cancer is difficult to be detected in time, thus delaying treatment. Based on the conventional CT images of gastric cancer, this study plans to develop, improve and validate an intelligent analysis system based on radiomics. By extracting and combining the radiomics features related to peritoneal metastasis of gastric cancer, the intelligent analysis system could predict the risk of peritoneal metastasis, and provide personalized decision suggestions for the treatment of gastric cancer.
This is a single-arm, open-label, dose-escalation study to explore the safety, efficacy, and cytodynamic characteristics of the drug, and to initially observe the efficacy of the drug in subjects with relapsed/refractory B7-H3-positive acute myeloid cell line leukemia.
This study is to assess the pharmacokinetics (PK) and safety of SC MK-3475A vs intravenous (IV) pembrolizumab, administered with chemotherapy in first line treatment of adult participants with metastatic non-small cell lung cancer. The primary hypotheses of this study are MK-3475A subcutaneous (SC) is noninferior to pembrolizumab IV with respect to PK parameters.
This is a single-center, prospective, observational and exploratory clinical study. The object of this study is to evaluate the accuracy of proteomics approaches on resected lymph node samples in evaluating lymph node metastasis status in cholangiocarcinoma patients.
The main aim of this study is to learn about the time between the start and stop of treatment with brigatinib in Chinese participants with non-small-cell lung cancer (NSCLC) and who have been positively diagnosed with having the anaplastic lymphoma kinase (ALK) gene. Other study aims are to learn about the progression of NSCLC and participants' response to treatment with brigatinib.
At present, there are few researches on peritoneal dialysis, especially on ultrafiltration failure of peritoneal dialysis. To explore the regularity and mechanism of peritoneal ultrafiltration failure,investigators followed up the comprehensive data of participants from the insertion to the removal of the peritoneal dialysis catheter, and collected the peritoneal tissue for morphological and single-cell analysis when the participants inserting or removing their catheters. If the catheter is still in use when this study stop collecting data, the peritoneal dialysis effluent will substitute for peritoneal tissue to the morphological and single-cell analysis. Clinical data and single-cell sequence data were processed using statistical analyses to identify factors affecting ultrafiltration failure.
Maintenance therapy is very important in advanced HER-2 negative gastric cancer, and immune monotherapy has no obvious benefit in the first-line maintenance treatment of advanced gastric cancer； Fruquintinib is a potent small-molecule VEGFR inhibitor with high kinase selectivity；Studies have shown that immunotherapy combined with antiangiogenic agents is promising for synergistic antitumor effects； The aim of this study was to observe and evaluate the efficacy and safety of Fruquintinib combined with PD-1 inhibitor in the first-line maintenance treatment of advanced HER-2 negative gastric cancer.
This study is the first clinical study in PD-1 resistant patients with head and neck squamous cell carcinoma with drugs targeting EGFR signaling pathway combined with CDK4/6 inhibitors, which explores the new combination therapies urgently needed in clinical practice and lays a foundation for subsequent studies, with important scientific research significance and clinical value.
We hypothesize incremental peritoneal dialysis (incremental PD) protocol with icodextrin solution will help patients to achieve adequate ultrafiltration and adequate dialysis with less glucose exposure by manipulating a low frequency of exchanges, therefore prolong the time from incremental protocol to full dose protocol (Full dose dialysis is defined as a dialysis dose of more than 8 L (4 exchanges of 2 L) per day). The goal of this clinical trial is to investigate the effect of icodextrin postponing the shift of low dose to full dose dialysis in the first year of incremental peritoneal dialysis. The main questions are: - The effect of icodextrin on the shift of low dose to full dose dialysis in the first year in patients on incremental peritoneal dialysis. - The effect of icodextrin on clinical outcomes in patients on incremental peritoneal dialysis, such as the first episode of peritonitis, the incidence of anuria, the first incidence of hospitalization, technical failure, all cause mortality, cardiovascular disease free survival and the quality of life. Participants will be 1:1 randomized to the ICO (icodextrin) arm and CON (control) arm. Both arms patients will be followed every 2 months for fluid status by bioimpedance analysis. An extracellular water /total body water (ECW/TBW) ≥ 0.40 or edema is defined as overhydration (OH). The OH patients in the ICO arm will be prescribed icodextrin (Extraneal) for long night dwell to improve fluid overload till their re-measurement of ECW/TBW < 0.40 or edema disappeared. The OH patients in the CON arm will be prescribed hypertonic Dextrose solution for long night dwell to improve fluid overload till their ECW/TBW < 0.40 or edema disappeared. Researchers will compare the time of transferring from low dose PD to full dose and the clinical outcomes in the first year between the patients in ICO and CON groups to see the effect of icodextrin on the shift of low dose to full dose dialysis and clinical outcomes in the first year in patients on incremental peritoneal dialysis. Successful completion of the study will advance our strategy of incremental PD and help to prolong the shift from incremental to full dose dialysis, and offer new opportunities for the development of an effective and economical therapy for PD patients with residual kidney function (RKF)
