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.
To evaluate the efficacy and safety of anlotinib plus TQB2450 combined with nab-paclitaxel and cisplatin as first-line treatment for advanced biliary tract cancer
This observational study includes patients at medium-to-high cardiovascular risks undergoing major noncardiac surgery, measures their baseline demographic and clinical characteristics, preoperative cardiac biomarkers and intraoperative surgery/anesthesia related data, and screens them for the occurrence of myocardial injury and major adverse cardiac events after surgery. The primary aim is to develop and validate a pre- and an immediate postoperative prediction model for occurrence of major adverse cardiac events.
Nipple discharge is one of the common symptoms of breast disease patients. Nipple discharge can be divided into physiological and pathological nipple discharge (PND). Among patients with PND symptoms who undergo biopsy, 5%-21% of them are malignant, and the risk of malignancy increases with age. The primary diagnostic imaging methods for PND patients include mammography and breast ultrasound. Nearly half of PND patients who undergo traditional mammography and ultrasound examination have negative findings, but this does not rule out the presence of malignant lesions. Central duct excision is the gold standard for PND diagnosis, but invasive surgery without imaging guidance can lead to some complications. Magnetic Resonance Ductography (MRD), which uses water imaging technology to visualize the inside of the duct without contrast injection, can show imaging features of ductal lesions such as filling defects, irregularities of duct walls, and ductal obstruction. However, previous studies have shown that the signal-to-noise ratio of MRD images needs to be improved. Microscopy coil has the characteristics of small voxels and high spatial resolution, making it suitable for high signal-to-noise ratio imaging of small superficial structures. This provides a hardware foundation for improving the quality of MRD images. Therefore, in this study, the investigators aim to use the 3T MR instrument and microscopy coil to perform non-invasive high-resolution Magnetic Resonance Ductography (HR-MRD) on PND patients to evaluate the ability of HR-MRD to detect PND causes and the imaging features of duct-related lesions on HR-MRD, to assist in the accurate diagnosis and treatment of PND.
1) Safety and efficacy of TCR-T cells in subjects with refractory/relapsed solid tumors. 2) The activation and proliferation of TCR-T cells in the subject, and the survival time.
Many RCT(randomized controlled trial) studies reported that tranexamic acid reduced blood loss in women who had elective cesareans. However, most of these elective cesareans are without high-risk factors of postpartum hemorrhage, such as placenta previa. The prophylactic use of tranexamic acid in the placenta previa is not clear. studies had poor quality and lacked adequate power to assess severe adverse events.
Repeated Red Light Therapy had been used as an amblyopia therapy for children as well as the myopia control in primary schools. However, ultra low lever of red light therapy with irradiance of 0.37mW and 0.60mW effectiveness and safety for 3~ 6 year-old myopia treatment or slow myopia progression are seldom reported.
. 1 Clarify the difference in efficacy of regofinib combined with TACE compared with second-line treatment of advanced liver cancer; 2. To evaluate the safety and prognostic imaging factors of regorofenib in advanced second-line therapy; 3, to explore whether it is necessary to increase the treatment of TACE in the second-line treatment of advanced HCC.
This is a multi-center, Phase IIa, randomized, double-blind, placebo-controlled study designed to evaluate the efficacy, safety of two doses of 50561 compared to placebo in participants diagnosed with mild to moderate Alzheimer's disease.
To evaluate the efficacy and safety of efgartigimod IV in Chinese patients with primary membranous nephropathy (pMN).
