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.
Echocardiography is the main method of bedside examination of neonatal cardiac morphology, which can timely diagnose congenital heart disease and quantitatively assess its severity, but the diagnosis and evaluation process depends on the normal range of neonatal echocardiography.At present, there have been normal reference standards for echocardiography in children and adults at home and abroad, but there is no uniform standard for echocardiographic parameters in newborns, especially premature infants.This study intends to carry out a national multicenter, prospective, observational study to establish the reference range of echocardiography at different time periods after birth in newborns, and stratified according to gestational age, birth weight and gender, to conduct a more accurate hemodynamic assessment of clinically critically ill newborns and guide the treatment of critically ill newborns in real time.
Current guidelines recommend moderate-intensity lipid-lowering therapy (goal for LDL-C <2.6 mmol/L or 30%-50% reduction from baseline) for patients with intermediate 10-year ASCVD risk. In these patients, early coronary atherosclerotic plaques (luminal stenosis<50%) detected by coronary CT angiography are common, but further interventions are lacking. This study aims to analyze whether intensive lipid-lowering therapy (goal for LDL-C <1.8 mmol/L or ≥50% reduction from baseline) could delay the progression of coronary atherosclerotic lesions and reduce the adverse cardiovascular events in these target patients.
Hirschsprung disease (HSCR) is characterized by the absence of ganglion cells (aganglionosis) in the distal bowel extending proximally for varying distances that results in persistent spasm in the affected bowel and functional intestinal obstruction. Patients can be classified as rectosigmoid HSCR when aganglionosis confined to the rectosigmoid and long-segment or total colonic HSCR when aganglionosis extends beyond the upper sigmoid. Aganglionosis of long-segment HSCR can extend to the descending colon, transverse colon, ascending colon, but not to the terminal ileum. To date, there is insufficient evidence to recommend a preferred or superior method for the surgical repair for long-segment HSCR. In general, a pull-through with standard of care for the intestine and mesentery, which avoids excessive resection of the colon and coloanal reconstruction, is performed for long-segment HSCR.There are reports that a significant percentage of long-segment HSCR patients continue to have difficulty with soiling and incontinence,however there were also reports long-segment HSCR patients have the same continece as rectosigmoid HSCR.The outcome of long-segment HSCR should be thoroughly evaluated. The present study was designed to evaluate the long-term outcomes of long-segment HSCR.
In this study, the dose of methimazole was adjusted according to the different states of thyroid function, and the effects of conventional therapy and intensive therapy on the cumulative recurrence of Graves' hyperthyroidism after two years of drug withdrawal were evaluated. At the same time, the changes of immune indexes and inflammatory factors in the regulation process were evaluated. This study is a phase IV clinical study designed and carried out by the First Affiliated Hospital of Nanjing Medical University (Jiangsu Province Hospital), which is a randomized, open and routine treatment group with parallel control.
Randomized-controlled trial to comparison of early radial artery occlusion via distal vs proximal radial artery among ST segment elevation myocardial infarction patients for primary percutaneous coronary intervention.
In phase Ia study, the safety and tolerability of BL-B07D1 in patients with locally advanced or metastatic HER2-positive/low-expression breast cancer and other solid tumors will be investigated to determine the dose-limiting toxicity (DLT), maximum tolerated dose (MTD) of BL-M07D1. In phase Ib study, the safety and tolerability of BL-M07D1 at the phase Ia recommended dose will be further investigated, and recommended phase II dose (RP2D) for phase II clinical studies will be determined. In addition, the preliminary efficacy, pharmacokinetic characteristics, and immunogenicity of BL-M07D1 in patients
The purpose of this study is to investigate whether the eradication rate of H.pylori will be improved when adding fucoidan to the duplex scheme combination of amoxicillin and vonoprazan, and to explore the effect of fucoidan on gastrointestinal flora of patients.
This study is a randomized, multi-center, double blind, Lucentis controlled non-inferiority study in neovascular age-related macular degeneration patients. The objective of this study is to compare the efficacy and safety of TAB014 and ranibizumab (Lucentis).
This is an open label, phase 1 clinical study to evaluate the safety, tolerability, dose limiting toxicities (DLTs), maximum tolerated dose (MTD) or maximum administered dose (MAD) and recommended phase 2 dose (RP2D) of QLS31904 q2w/q3w intravenous use in patients with advanced solid tumors. Additional objectives are to characterise pharmacokinetics and pharmacodynamics, and to evaluate efficacy signals. This study is consisted of phase Ia (Dose Escalation) and phase Ib (Dose Expansion). Phase Ib will further explore QLS31904 in selected patients populations based on data from phase Ia. The Phase Ib objectives, endpoints and design will be specified in a study protocol amendment after availability of phase Ia results.
This randomized controlled trial was designed to evaluate the efficacy and safety of Docetaxel combined with Platinum-based drugs compared with Docetaxel alone for metastatic hormone-sensitive prostate cancer patients carrying DNA repair mutation.
