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 purpose of this clinical trial is to learn about the safety and effects of the study medicine (called marstacimab) for the potential treatment of hemophilia in pediatric patients. This study will enroll pediatric participants from ages 1 to 17 years in a sequential manner. The study will open enrollment to adolescent participants aged 12 to 17 years first. Then children aged 6 to 11 years will be permitted to enroll. Lastly, children aged 1 to 5 years will be permitted to enroll. This study will enroll participants who: - have severe Hemophilia A or moderately severe to severe Hemophilia B (with or without inhibitors) - have accurate historical records documenting all factor VIII, factor IX, or bypass agent infusions and hemophilia bleed events for at least 1 year prior to entering the study - if a non-inhibitor patient, must be on a stable routine prophylaxis regimen with factor VIII or factor IX replacement products for at least 12 months prior to study entry - if an inhibitor patient, must be on an on-demand bypass treatment regimen during the 12 months prior to study entry All participants in this study will receive marstacimab to use prophylactically. Marstacimab will be given once a week as a subcutaneous (under the skin) shot. The first dose of marstacimab will be given at the study site by the study site staff. During the 12-month treatment period, weekly doses of marstacimab can be given at home, or if preferred, the doses may be given by the study site staff. To help us determine if the study medicine is safe and effective, we will compare participant experiences when they are taking the study medicine to a historical period when they were not. Researchers want to see if the study medicine works to prevent the bleeding episodes commonly experienced by patients with Hemophilia. Participants will be in this study for about 14 months (approximately 1 month in a Screening period, 12 months receiving treatment, and 1 month in a follow-up period) during which they will visit the study site at least 10 times. If preferred, and if local regulations allow it, 2 of the study visits can be completed at the participant's home instead of at the study site. There will also be 6 scheduled telephone calls approximately every 2 months.
The goal of this observational study is to learn about the morphological characteristics of different bladder lesions under narrow-band imaging（NBI） techniques in All patients requiring cystoscopy and biopsy. The main questions it aims to answer are: 1. To clarify the characteristics of different bladder lesions under NBI and to establish a diagnostic classification system for bladder tumors under NBI based on pathological findings. 2. Verify the accuracy of this classification system. Participants will record the morphological characteristics under ordinary white light and NBI during cystoscopy, analyze the pathological characteristics of different tissues corresponding to the NBI characteristics, establish a diagnostic classification system for bladder tumor under NBI using pathological biopsy as the diagnostic standard, and then verify the accuracy of this classification standard through clinical.
The effect of polyethylene glycol Losenatide on body fat, insulin resistance, weight, blood sugar, blood lipid, stomach volume and other factors in patients with type 2 diabetes through 12 week follow-up, and explore the factors affecting the efficacy, so as to provide more evidence-based medical basis for drug treatment and benefit patients.
This randomized phase II trial studies how well lose dose bevacizumab with Hypofractionated Stereotactic Radiotherapy (HSRT) works versus bevacizumab alone in treating patients with glioblastoma at first recurrence. The primary endpoint is 6-month progress-free survivaloverall survival after the treatment. Secondary endpoints included overall survival, objective response rate, cognitive function, quality of life and toxicity.
the purpose of this study is to assess the efficacy and safety of camrelizumab plus Docetaxel and Cisplatin as First-line Therapy in Recurrent or Metastatic Oral Squamous Cell Carcinoma Patients
Mechanical ventilation will bring many adverse effects. Positive pressure can affect hemodynamics. Inhalation of higher concentrations of oxygen during mechanical ventilation can result in reabsorbed atelectasis for the lungs with a low ventilation-perfusion ratio. Patients who are intubated and mechanically ventilated are at risk for ventilator-associated pneumonia. Mechanical ventilation can induce or aggravate lung injury, called ventilator-induced lung injury (VILI) , Minimizing the duration of mechanical ventilation is the best way to reduce complications. Sevoflurane is a halogen group of inhaled anesthetics commonly used in clinical, with sedation, analgesia, muscle relaxation. Sevoflurane also inhibited respiratory function, tidal volume decreased with the depth of anesthesia, respiratory rate increased, higher than the conscious respiratory rate, but not enough to fully compensate for the decreased tidal volume. The results showed that with the increase of the depth of anesthesia, the minute ventilation decreased, and the ability to remove carbon dioxide also decreased. Based on the background of the study and the pharmacological properties of sevoflurane, we sought to explore the maximum alveolar concentration of sevoflurane for maintaining effective spontaneous respiration in patients, i.e.FiO2 = 30% , PaO2 > 92% , VT > 5 ml/kg, RR > 8/min, PETCO2 < 50 mmHg, sustained > 20s, the time from the beginning of inhalation induction to 1 point OAAS, the changes of hemodynamics during induction, and the recall of induction and operation were also explored.
To evaluate the safety and tolerability of GS3-007A in single, multiple, and single oral administration after high-fat meals in Chinese healthy adults.
This study intends to take patients with RGD as objects. Further construct a community-based rehabilitation management (CBRM) program with drug treatment, rehabilitation measures of education, psychology and exercise as its core content on the basis of evidence-based practice approach. Based on the cost-utility analysis of health economics, the health and economic benefits of the CBRM program will be evaluated, and a theoretical reference will be provided for community health institutions to carry out whole-course rehabilitation management practice and health policy formulation.
Anastomotic leakage is one of the most serious postoperative complications of low rectal cancer, with an incidence of 3%-21%. The occurrence of anastomotic leakage is related to many factors, and the occurrence of anastomotic leakage can be predicted by building a prediction model. Most of the anastomotic leakage prediction models constructed in the past are nomograms, which have limitations in the fitting of model creation. In the previous study, the center took the lead in building a random forest anastomotic leakage prediction model based on machine learning. This study intends to prospectively enroll patients with rectal cancer undergoing anterior abdominal resection and use their clinical data to prospectively verify the efficacy of the anastomotic leakage prediction model, and further improve and promote the prediction model.
This study investigates the ability of tumor budding to identify prognosis in different MMR states and different levels of tumor lymphocyte infiltration. Tumor budding is usually defined as an isolated single cancer cell or a cluster of up to four cancer cells located at the front of an infiltrating tumor.
