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.
Recent small subcortical infarction (RSSI) is defined as a small deep infarction in the territory of a perforating artery with maximum axial diameters (MAD) of less than 20 mm. Although RSSI is generally considered to be of a relatively favorable prognosis, about 13.5% to 43% of RSSI patients experience early neurological deterioration (END) in the acute phase, which often bring adverse effects on long-term outcomes. Although a number of risk factors for END have been identified previously, however, the risk factors of END and the underlying etiological mechanism are still ambiguous, and also the relevant intervention measures lack sufficient evidences, which is a thorny problem that clinicians have to face. In this multicenter, large-sample prospective registry study, we ought to investigate the natural course of END in patients with RSSI. Exploring the risk factors and potential mechanism of its occurrence and development, and trying to establish a comprehensive predictive model for END that integrates multi-dimensional information including clinical symptom, demographic data, biochemical biomarker and image data, and so as to provide a valuable tool for clinical evaluation and early management. Simultaneously, our study will provide information for the design of therapeutic randomized controlled trials in the future.
This is a phase 1, open-label study to assess the efficacy, safety and pharmacokinetics of ThisCART19A (Allogeneic Anti CD19 CAR-T) bridging to HSCT in patients with refractory or relapsed B cell acute lymphoblastic leukemia (r/r B-ALL).
Elderly patients are vulnerable to postoperative complications. Preoperative malnutrition and poor oral hygiene are risk factors for postoperative complications especially pulmonary complications. This study aims to investigate the feasibility and efficacy of perioperative oral decontamination and immunonutrition supplement on reducing postoperative complications in elderly surgical patients.
This study included two topics: one was to test the efficacy and safety of fecal microbiota transplants plus partial enteral nutrition (PEN) in refractory pediatric UC where conventional therapy has failed, and the other was to explore the efficacy and safety of FMT plus PEN as first-line therapy for pediatric active UC
COVID-19 remains a widespread global epidemic, increasing morbidity, mortality, healthcare resource consumption, and socio-economic burden on patients worldwide. The onset of COVID-19 ranges from mild, self-limiting respiratory disease to severe progressive pneumonia, mainly acute respiratory distress syndrome (ARDS), with critically ill patients requiring admission to the intensive care unit (ICU). Prone positioning has been shown to improve oxygenation and reduce complications and mortality in patients with severe ARDS. Prone position increases functional residual volume and chest wall elasticity, reduces dorsal segment edema in both lower lungs, facilitates uniform ventilation distribution, improves V/Q ratio, reduces alveolar shunts, and aids secretion drainage. In clinical practice, the prone position is mainly used for patients with diffuse bilateral lung lesions. However, it is less effective in unilateral or predominantly upper lung patients. Moreover, some patients are unable to tolerate prone ventilation. Therefore, we construct an individualized approach to postural oxygen therapy by guiding the patient's position based on the pulmonary imaging information. A study on the optimal ventilation position for patients with severe COVID-19 will be conducted at the Department of Respiratory and Critical Care Medicine, Wuhan Union Hospital. The investigators enrolled adult patients (without endotracheal intubation) diagnosed with severe COVID-19 requiring oxygen therapy from 2023.01.10 to 2024.01.10. Patients were grouped into control and intervention groups according to current treatment protocol and pulmonary imaging combined with patients' wishes and degree of postural tolerance. Patients in the intervention group were ventilated in different positions according to pulmonary imaging, including prone, left/right lateral, supine, semi-recumbent, and seated. In contrast, patients in the control group were ventilated comfortably according to the treatment principles and their wishes. The primary observation was 28-day mortality. Secondary observations were oxygenation index (PaO2/FiO2) before and after a position change, endotracheal intubation rate, duration of respiratory support, length of hospital stay, and comfort in position.
ASCEND-BRAIN is a prospective, observational study aimed at early-detection of intracranial tumors by combined assays of cfDNA methylation and other biomarkers. The study will enroll approximately 358 participants including intracranial malignant tumors, patients with benign disorders of central nervous system and healthy participants.
Based on the safety and benefit of neoadjuvant therapy for patients with pancreatic cancer in the available evidence, as well as the principle of sequential chemotherapy with different regimens and the existing preliminary investigation , the aim of this study was to further explore the efficacy and safety of neoadjuvant therapy with AG regimen followed by FOLFIRINOX regimen in patients with resectable pancreatic cancer, and to assess the impact of neoadjuvant therapy on the health-related quality of life of patients, in order to bring new treatment options for neoadjuvant therapy of pancreatic cancer.
This is a single-arm, open-label, multi-center phase 2 clinical trial of ICP-192. The purpose of this study is to evaluate the efficacy and safety in patients with FGFR2-Rearranged unresectable or metastatic intrahepatic cholangiocarcinoma who failed prior therapy
We did an multi-centre, observational cohort study in patients who had surgery in 2023. We included participants who underwent surgery after the COVID-19 to lift the lockdown in China. Patients meeting the same criteria were eligible who had been treated during the same calendar period of 2019 through 2021. The primary outcomes were the post-operative in-hospital complications. We hypothesized that the post-operative in-hospital complications during the COVID-19 to lift the lockdown period in China were different to complications for the same kind of patients during the same calendar period of the previous years.
In the assessment of severity in coronavirus disease 2019 (COVID-19), the modified Brit_x0002_ish Thoracic Society (mBTS)，CURB65 et al. rules identifies patients with severe pneumonia but not patients who might be suitable for home management. A multicentre prospective study was conducted to derive and validate a practical severity assessment model for stratifying adults hospitalised with COVID-19 into different management groups.
