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.
the early application of non-invasive PNS in MV patients can increase the number of days without mechanical ventilation, delay disuse phrenic atrophy, and improve the strength of inspiratory muscle.
Monotherapy with DPP-IV inhibitors, SGLT-2 inhibitors or insulin secretagogues frequently failed to maintain blood glucose in patients with type 2 diabtes. It was critical to determine which was more suitable of acarbose versus metformin plus pioglitazone.
The purpose of the study is to explore the optimal dose and administration of the experimental drug, and to evaluate the safety and efficacy of the drug in patients with renal anemia. Patients with renal anemia on regular dialysis treatment are expected to be enrolled in this study.
This is a Phase III, randomized, open-label, 3-arm, multicenter, international study assessing the efficacy and safety of Dato-DXd with or without durvalumab compared with ICT in participants with stage I to III TNBC with residual invasive disease in the breast and/or axillary lymph nodes at surgical resection following neoadjuvant systemic therapy.
Urinary incontinence (UI) is a common disease that refers to involuntary loss of urine. The prevalence of female UI varies widely across different studies, mostly ranging from 25-40%. Stress urinary incontinence (SUI) is the most common type of UI. SUI is defined as involuntary loss of urine when abdominal pressure increases suddenly such as coughing or sneezing. SUI affects women's quality of life seriously, causing psychological problems such as anxiety and depression, even socialization difficulties. There are many treatment options for female SUI, including non-surgical and surgical interventions. Clinicians and patients need a highly effective and low-risk therapy urgently, thus energy-based therapies were born on demand. This study aims to demonstrate the efficacy and safety of the fractional CO2 laser in the treatment of female SUI, as well as its impact on women's quality of life.
The goal of this observational study is to compare the incidence of relapse in G-CSF/ATG based and PT-Cy based haploidentical transplantation] in [patients aged 18 to 55 years with a diagnosis of hematological malignancies who unmanipulated haplo-HSCT with myeloablative conditioning]. The main question it aims to answer are: Primary objective: To compare the incidence of relapse in G-CSF/ATG based and PT-Cy based haploidentical transplantation and illustrate the possible immune mechanism. Secondary objectives: To compare CMV infection, GVHD and survival outcomes, and to observe the dynamic immune reconstitution of G-CSF/ATG based or PT-Cy based model. Exploratory objectives: To compare the long-term quality of life among recipients who receive G-CSF/ATG based or PT-Cy based protocol.
The goal of this observational patient registry is to learn how expert centers treat patients with chronic thromboembolic pulmonary hypertension (CTEPH). CTEPH is a condition in which blood clots block the blood vessels in the lungs. There are currently three treatment options for patients with CTEPH: - surgery to remove blood clots from large vessels in the lungs (pulmonary endarterectomy (PEA)) - the use of a small balloon to unblock smaller blood vessels (balloon pulmonary angioplasty (BPA)) - drugs Patients can also receive a combination of these treatments. The main question this registry aims to answer are: - How many patients receive a given kind of treatment? - How do expert centers combine the different treatments? - Are patients doing better after they receive a given kind of treatment? - How many patients are alive 1, 3 and 5 years after they receive a given kind of treatment? Participants will receive the same treatments that they would receive if they did not participate in the study. During the study, patients will visit their doctors as they would do normally. The doctors will collect information on the patients' health and enter it into the study database. The follow-up time will be at least 3 years for all patients.
The goal of this observational study is to learn about how to utilize multiple evaluation techniques in carotid artery stenosis patients for optimizing assessment of diagnosis and treatment strategy. The main questions it aims to answer are: - Identify best strategy that use multi-modal MRI and CT to assess patients' cerebral lesions and perfusion. - Identify best strategy that use multi-modal MRI, PET-MRI ultrasound and CT to assess components and characters of patients' carotid plaques. Participants will accept imaging examination before and after surgery. And doctors will collect basic characteristics, imaging results and biological samples of patients for analysis.
This is a multicenter, case-control study that aims to investigate the relationship between microbiota and sperm quality via stool, blood, and urine microbiome, metabolomics, and collected clinical metadata. The results of the spermatogenic dysfunction, including aspermia, oligozoospermia, asthenozoospermia, and teratozoospermia, will be compared to normal basic semen analysis utilizing the World Health Organization (WHO) semen analysis procedure 5th edition.
Nasopharyngeal carcinoma is biologically different from traditional head and neck squamous cell carcinoma. The mainstay treatment for locally advanced nasopharyngeal carcinoma is cisplatin-based concurrent chemoradiation. Recent phase III randomized control trials have demonstrated that induction chemotherapy plus concurrent chemoradiation further improved progression-free survival. However, not every patient has good response to induction chemotherapy. Evidence has accumulated that those with poor response to induction chemotherapy, or those with detectable Epstein-Barr Virus (EBV) DNA post induction chemotherapy, correlated with poorer progression-free survival. Huang CL et al. (Int J Radiat Oncol Bio Phys. 2019) reported that plasma EBV DNA load at completion of induction chemotherapy was an independent and earlier predictor for progression-free survival and overall survival in locally advanced nasopharyngeal carcinoma. Lv J et al. (Nat Commun. 2019) demonstrated that real-time monitoring of plasma EBV DNA response added prognostic information, and had the potential uitility for risk-adapted treatment intensification in nasopharyngeal carcinoma. Therefore, investigators selects those with poor plasma EBV DNA response during and after induction chemotherapy, and intensifies the treatment with combination of anti-PD-1 antibody, in order to improve progression-free survival in locally advanced nasopharyngeal carcinoma, according to response-adapted strategy.
