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.
By incorporating dual-tracer PET/CT (PSMA and FDG) and ctDNA, we aimed to evaluate lesion heterogeneity and genomic change of mCRPC patients receiving novel hormonal therapy. The relationship between treatment response and different molecular characterization, as well as imaging features would also be evaluated.
Chronic kidney disease (CKD) refers to a variety of different diseases characterized by impairment of kidney structure and/or renal function. The prevalence of CKD in China is as high as 10.8%. With a population of more than 150 million, China has the largest number of CKD patients all over the world. People with CKD would not only progress to uremia and need renal replace treatment, it also significantly increases risk of cardiovascular disease than non-CKD population. It has created a heavy burden on people's health and national economy. There is an urgent need to establish an effective system for CKD prevention and control in China. Evidences from large sample cohort and real world based research are still rare. This study will provide good experience for reducing the occurrence and development of CKD.
Primary aldosteronism is the most common cause of secondary hypertension. The two main types of primary aldosteronism are aldosteronoma(30%) and adrenal hyperplasia(60%). The gold standard that determines the diagnosis and treatment strategy of primary aldosteronism is adrenal vein sampling(AVS), but the success rate is only about 80%. Using CXCR4 as a probe for 68Ga-Pentixafor PET/CT imaging can guide the classification diagnosis and treatment strategy of primary aldosteronism, which is a favorable supplement to AVS. Superselective adrenal artery embolization(SAAE) and laparoscopy are the main operation treatments for primary aldosteronism. SAAE is an invasive interventional operation. It is a novel way to evaluate the changes in the structure and function of adrenal tissue pre-postoperative SAAE by using the changes in 68Ga-Pentixafor PET/CT imaging.
Currently, data of the efficacy of trastuzumab plus pertuzumab and chemotherapy is limited in the HER2 positive metastatic breast cancer patients previously treated with trastuzumab during (neo)adjuvant and metastatic setting, and results are not consistent.The main purpose of this study is to evaluate the 6-month progression free survival(PFS) of trastuzumab(Henlius®) combined with Pertuzumab(Perjeta®) and Chemotherapy as first to third line therapy in Chinese patients with HER2 positive metastatic breast cancer who received trastuzumab previously.Primary Endpoint is 6-month Progression-free survival (PFS);Secondary Endpoint(s) include Progression-free survival (PFS) Overall Survival (OS);Objective Response Rate(ORR);
The objective of this study is to assess the safety, efficacy, pharmacokinetics, and immunogenicity of MRG003 in patients with EGFR-positive, HER2-negative, inoperable locally advanced or metastatic gastric cancer.
The study aims to evaluate the efficacy of ridge preservation with collagen sponge or collagen membrane in combination with collagenated bovine bone mineral in extraction sockets of periodontally diseased teeth.
Post-stroke depression (PSD) is a common complication of stroke that leads to dysfunction and reduces the quality of life. PSD exacerbates cognitive dysfunction, delays the recovery process, and increases the disability, mortality and recurrence rates of stroke. Therefore, early clinical treatments for PSD are important to improve the prognosis and restore the social functions of stroke patients. Integrated rehabilitation has significant advantages in the treatment of PSD. First of all, there is a wide range of rehabilitation methods, such as acupuncture, traditional Chinese medicine, and repetitive transcranial magnetic stimulation, which have been proved to be effective for PSD. However, as the application of integrated rehabilitation becomes more and more widespread, its shortcomings are gradually emerging. For example, most of the treatment protocols used in clinical studies are based on personal experience of the investigators, a unified protocol has not yet been formed; treatment methods are still insufficient in standardization and reproducibility. More studies focus solely on the improvement of a certain symptom by a certain rehabilitation therapy, but ignore the important theoretical basis of the "holistic concept", thus showing the uneven clinical efficacy. For the above existing problems, it is necessary to conduct original and innovative research.
The aim of this study was to evaluate the diagnostic efficacy of computer aided diagnostic tool for neck masses using machine learning and deep learning techniques on clinical information and radiological images in children.
This study will take progression-free survival and overall survival as the main evaluation indexes, to evaluate the Efficacy of Jianpi Huatan Decoction in the Treatment of Advanced Colorectal Cancer. Decision Trees and Discriminant Analysis will be used to analyze the characteristics of dominant population combined with clinical data of patients. DNA methylation of the subjects will be detected to study the methylation characteristics of the preponderant population of Jianpi Huatan Decoction.
The purpose of this study is to illustrate pharmacokinetics of sugammadex in reversal of rocuronium-induced moderate neuromuscular blockade in patients during renal transplantation
