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 study is a single-center, open-label, crossover study, conducted in healthy Chinese populations, and plans to enroll 48 healthy adult subjects (male and female).
The purpose of this trial is to demonstrate the clinical efficacy of GR1501 at week 16; and to demonstrate safety and tolerability of GR1501 compared to placebo in patients with Radiographic Axial Spondyloarthritis at week 16 and long term safety up to Week 48。 The main question it aims to answer is whether GR1501 injection was superior to placebo in the proportion of subjects with ASAS20 response at week 16 in patients with Radiographic Axial Spondyloarthritis.
In this study, colorectal cancer patients with initially resectable liver-only metastases, as prospectively confirmed by a local multidisciplinary team (MDT) according to predefined criteria, will be tested for RAS and BRAF tumor mutation status. Patients with gene mutant or right-sidedness will be randomised between anatomical resection (AR) or nonanatomical resection (NAR). The primary end-point is the relapse-free survival.
Acute-on-chronic liver failure refers to a liver failure syndrome in which some patients with chronic liver disease with relatively stable liver function suffer from acute liver decompensation and liver failure due to the effects of various acute injury factors. Liver transplantation is the only curative treatment for this type of end-stage liver disease. The potential of MSCs to repair or regenerate damaged tissue and suppress immune responses makes them promising in the treatment of liver diseases, especially in the field of liver transplantation. Many studies have shown that MSC-based therapies can reduce the symptoms of liver disease due to their paracrine effects. Therefore, compared to the cells they derive from, mesenchymal stem cells-derived extracellular vesicles (MSC-EV) are gradually gaining attention for their enhanced safety, as they do not replicate or cause microvascular embolism, and can be easily stored without losing their properties. It represents a novel and effective cell-free therapeutic agent as alternative to cell-based therapies for liver diseases, and liver failure was also concerned. This study was designed to evaluate the safety and tolerability of MSC-EV in acute-on-chronic liver failure after liver transplantation.
It is a prospective clinical control study on red light control myopia with specail design spectacles for 75 children in 3 groups. Study Groups with two different powers of 0.6 mW and 1.2 mW at wavelength of 650nm. The control group is to wear the same brand and design spectalces as those two study groups. In addition, the progression of myopia is usually accompanied by the changes in a variety of ocular parameters, such as refractive error, reduced submacular choroidal thickness, and prolonged length of the ocular axis length.The goal is to test which power (1.2mW and 0.6mW) is better in myopic children for 3 month's follow-up and also to test how to get better result with the increaing or decreasing lighting power for the total 6 month follow-up results .
With the same tumor control rate as classic radical cystectomy, radical cystectomy with partial preservation of the prostate and seminal vesicle can effectively preserve penile erection and fertility, improve urinary control rate and shorten hospitalization time. In this project, transurethral resection of the prostate was used to remove part of the prostate, which further reduced the trauma of radical cystectomy and better preserved the nerves and urethral sphincter. Rapid intraoperative examination of resected tissue can provide a basis for the selection of surgical options. Robot-assisted radical cystectomy can perform pelvic lymph node dissection more accurately, preserve neurovascular complex more effectively, and improve the control effect of tumor and the protective effect of sexual function and reproductive function. In view of the shortcomings of the internationally accepted orthotopic ileal neobladder, this study improved the operation according to the physiological and anatomical characteristics, restored the orthophoria of the new bladder, maintained the consistency of physiological anatomy, and minimized the bladder pressure.
This study aims to collect serum samples from healthy non-pregnant women, pregnant women with and without Gestational Diabetes Mellitus (GDM). We will analyze the metabolite changes among the three groups using clinical metabolomics and identify potential biomarkers and metabolic pathways. This study will provide scientific evidence for early clinical diagnosis, prevention, control, and treatment research of GDM.
New York Esophageal Squamous Cell Carcinoma 1 (NY-ESO-1) is a cancer-testis antigen (CTA) which is expressed in various tumors. In TCR-T therapy, researchers take the blood of a certain patient, select T cells and insert genes into the cell that expressing a kind of protein that targeting NY-ESO-1. The genetically engineered cells are called NY-ESO-1 TCR-T cells. Then the engineered cells are re-infused to the cancer patients to cure the disease or prolong life.
Aortic valve stenosis is the most common debilitating valvular heart lesion in old patients. Transcatheter aortic valve replacement (TAVR) is an emergent technique for high-risk patients with aortic stenosis. In recent times, treatment has expanded to also include low- and intermediate-risk individuals. General anesthesia offers many advantages, mainly regarding the possibility of an early diagnosis and treatment of possible complications through the use of transesophageal echocardiography. Propofol is the most used sedative-hypnotic agent for the induction and maintenance of general anesthesia. However, adverse events such as hypotension, and bradycardia are associated with propofol sedation. Ciprofol is a novel anesthetic/sedative agent similar to propofol, with an equivalent efficacy ratio to propofol of 1/4 to 1/5. Ciprofol has properties of fast onset of action, rapid recovery, reduced injection pain and stable cardiorespiratory function, making it a promising alternative to propofol. The aim of this study is to explore the safety and efficacy of ciprofol when used for general anesthesia in patients undergoing transcatheter aortic valve replacement compared to propofol.
Based on the current treatment with retinoic acid (ATRA) and arsenic (As), most patients with APL achieved long-term survival. There are few patients relapsed and became refractory to the RA and As treatment. In our pre-clinical study, we found that targeting histone deacetylase inhibitor 3 (HDAC3)degraded PML-RARa oncoprotein and induced differentiation and apoptosis of RA and As resistant APL in vitro and in vivo. In this study, we evaluate the efficacy and feasibility of combination therapy for HDAC3 inhibitor and venetoclax in patients with refractory APL.
