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.
A phase 3 study to evaluate the efficacy and safety of SY-3505 vs. crizotinib in patients with ALK-positive non-small cell lung cancer who had not received prior systemic therapy.
This study was conducted to investigate whether the use of tourniquet after delivery of the fetus could reduce the amount of amniotic fluid entering the bloodstream and thus reduce the incidence of intraoperative adverse events.
The main purpose of this study is to investigate the efficacy and safety of JY09 versus placebo in patients with type 2 diabetes mellitus (T2DM) inadequately controlled by diet and exercise alone
To evaluate the efficacy and safety of lithium-containing mouthwash for prevention and treatment of oral mucositis and dysgeusia in patients undergoing radiotherapy for malignant head and neck tumors.
Our aim is to compare early versus late pancreatic stent placement in preventing PEP among patients with naive papilla. The EVL trial will provide essential answers regarding the optimal timing of prophylactic pancreatic stent placement in PEP prevention.All patients with difficult biliary cannulation undergoing endoscopic retrograde cholangiopancreatography (ERCP) with pancreatic guidewire-assisted technique for biliary access will be told about the opportunity to participate in EVL research. In total, 768 patients will be randomly assigned (1:1) to two arms: (1) early pancreatic stent placement (EPSP) (a pancreatic stent will be placed immediately after endoscopic retrograde cholangiography (ERC) or endoscopic sphincterotomy (EST)) and (2) late pancreatic stent placement (LPSP) (a pancreatic stent will be placed after all completion of therapeutic biliary procedures, e.g. biliary stone removal or drainage).The primary outcome is the rate and severity of PEP. The secondary outcomes are hyperamylasemia, the rate of stenting success, and other ERCP-related adverse events (AEs).
Based on the comprehensive etiological screening results of patients with recurrent pregnancy loss, including basic characteristics, coagulation function indicators, autoimmune indicators, endocrine indicators, and gynecological ultrasound examination results, as well as the outcome of subsequent pregnancy after the patient's visit, analyze the independent risk factors affecting recurrent pregnancy loss, construct and validate an abortion risk prediction model to predict the risk of subsequent pregnancy loss in patients with recurrent pregnancy loss, and classify the patient's risk, Screening high-risk populations and guiding clinical early intervention and active treatment to improve pregnancy success rates.
This is an exploratory, single-arm, multi-center study to assess the efficacy and safety of T-DXd combined with pyrotinib as the first-line treatment of HER2-positive metastatic breast cancer. This study is planned to recruit 3 to 12 patients in safety run-in (Part A) and 39 to 42 patients in dose expansion (Part B) in several investigational sites in China. The total number of patients enrolled in the study will be 45 to 51. Among them, 45 patients will start at the recommended dose. Patients who fulfill all the inclusion criteria and none of the exclusion criteria will receive T-DXd combined with pyrotinib until confirmed progressive disease. Patients will attend a safety follow up visit 40 days after last dose of T-DXd with pyrotinib. There are two main parts to this study; Part A, Combination dose finding and Parts B, Dose expansion. Tumor assessments will be performed at Screening as baseline with follow-up every 9 weeks(±7 days) from the date of first dosing date of T-DXd with pyrotinib for 54 weeks, and then every 12 weeks (±7 days) until confirmed objective disease progression. Primary Objective for Part A: To define the recommended dose of pyrotinib combined with T-DXd Recommended dose Secondary Objective for Part A: To investigate the safety and tolerability of T-DXd + pyrotinib as first-line treatment of HER2-positive metastatic breast cancer. Primary Objective for Part B : To determine the efficacy of T-DXd + pyrotinib as first-line treatment of HER2-positive metastatic breast cancer. Secondary Objective for Part B : To further determine the efficacy of T-DXd + pyrotinib as first-line treatment of HER2-positive metastatic breast cancer and To further evaluate the safety and tolerability profile of T-DXd + pyrotinib as first-line treatment of HER2-positive metastatic breast cancer.
To observe the improvement of Chalder scale score in patients with chronic fatigue syndrome treated by compound Ciwujia granules. Improvement =[(baseline score - post-treatment score)/baseline score]*100%
The primary objective of this study is to evaluate the protective efficacy against future infections of HPV types 16/18 or related diseases and immuno-persistence (type specific IgG antibody) of the bivalent HPV vaccine in young female populations aged 9-17 years.
Early exploratory clinical study of the safety, tolerability and initial efficacy of JY231 injection in the treatment of refractory autoimmune diseases
