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.
Pancreatic ductal adenocarcinoma (PDAC) is a dismal disease with a 5-year survival rate as low as 6%. It causes body composition changes and many patients develop muscle loss with disease progression. Computed tomography (CT) is a common, noninvasive method of muscle assessment.Known as myoesteatosis,low muscle radiodensity is reflective of intermuscular adipose tissue that influences survival outcomes in patients with cancer.Serum creatinine (Scr) and cystatin C (CysC) are usually employed to estimate renal function in clinical practice. Scr is a metabolic waste product produced by creatine in skeletal muscle. CysC can be produced by all nucleated cells in the body at a constant production rate. CysC is used as an endogenous marker to reflect the glomerular filtration rate. Some studies have supported that the Scr/CysC ratio (CCR) is a simple and inexpensive measure that can be used to evaluate the skeletal muscle mass of patients with malignancies, such as gastric cancer. Therefore, the purpose of the present study is to explore the association between CCR and myosteatosis upon diagnosis of PDAC, specially whether the co-occurrence of these factors could predict survival outcomes.Preoperative assessment of muscle quality may be valuable for treatment planning and optimization of nutritional support. This retrospective study enrolls patients who underwent surgery for PDAC, from January 2016 to December 2021. Patients will be divided into myosteatosis and non-myosteatosis groups. Clinical and imaging data are collected.The study does not have any intervention measures and harm to subjects.
A clinical study to assess dose escalation, tolerance, safety, pharmacokinetics, and multi cohort expansion of ZGGS18 in patients with advanced solid tumors
This research is being done to study the efficacy and safety of unrelated umbilical cord blood stem cell microtransplantation combined with azacitidine(AZA) based treatment for advanced myelodysplastic syndromes(MDS), Chronic myelomonocytic leukemia-2(CMML-2) and secondary acute myeloid leukemia(sAML). The study protocol involved unrelated umbilical cord blood stem cell combined with azacitidine based treatment, which including azacitidine alone and azacitidine plus a targeted agent or chemotherapy agent.
The goal of this observational study is to explore the correlation between the difficulty of colonoscopy and the patients' personality in the population receiving initial colonoscopy in Peking Union Medical College Hospital. The main question it aims to answer is: Whether the difficulty of colonoscopy is related to any personality score of big five personality dimensions Participants will: 1. Receive routine colonoscopy 2. Fill out the GAD-7 and PHQ-9 scales 3. Fill out the Big Five Personality Questionnaire.
This study is designed to evaluate the vaccine efficacy, immunogenicity and safety of the 4-valent Human Papillomavirus (Types 6, 11, 16, and 18) Recombinant Vaccine (Hansenula Polymorpha) in Chinese Female Subjects Aged 18-45 Years .
Empagliflozin was recommended for patients with heart failure with reduced ejection fraction (HFrEF) in 2021 European Society of Cardiology (ESC) guidelines (Class of Recommendation Ia) and patients with heart failure with preserved ejection fraction (HFpEF) in 2022 American Heart Association (AHA) guidelines (Class of Recommendation IIa). However, the physiopathologic mechanisms in its effects on HFpEF are not clear. Studies illustrate that gut microbiota plays an essential role in the progress of the heart failure. Studies on mice found that sodium-glucose cotransporter-2 inhibitors (sglt-2i) could affect the intestinal microbiota in mice. The purpose of this study is to clarify the changes of gut microbiota in the patients with HFpEF taking Empagliflozin and explore the role of gut microbiota in this process.
This study will assess the safety, tolerability, pharmacokinetics and preliminary efficacy of 610 as an adjunctive therapy in adult subjects with severe eosinophilic asthma.
This is a prospective multicenter clinical study. This study aims to construct an auxiliary decision-making system for lung cancer immunotherapy combined with radiotherapy by fusing three modes of imagomics, clinicopathological features, and molecular pathological features.
This study is a phase II study to evaluate the efficacy, safety and tolerability of HLX26 and HLX10 in the treatment of patients with metastatic colorectal carcinoma that had received 3 prior therapies.
Background: Arthroscopic anterior cruciate ligament(ACL) reconstruction is so far the gold standard for the treatment of ACL ruptures, but this technique still suffers from problems of tendon-bone healing, bone tunnel enlargement, bone resorption, a low rate of return to motion,etc. In recent years, due to the innovation of medical materials and surgical techniques, anterior cruciate ligament repair technology has returned to the field of vision of clinical doctors. This technique has the advantages of preserving the natural ligaments and their proprioceptive sensation, avoiding the bone injury of the tunnel and the complications of the donor site. However, there is still a lack of high-quality clinical randomized controlled trails to provide evidence of the effect of arthroscopic ACL repair. Hypothesis: Arthroscopic ACL repair is comparable to ACL reconstruction in patients with ACL tears (Sherman grades I and II). Study Design: This study was a prospective, multicenter, randomized, double-blinded, parallel-controlled, non-inferiority trial design. A total of 330 patients with ACL tears were randomly divided into 2 groups, and were randomly assigned to the experimental group (arthroscopic anterior cruciate ligament repair) and the control group (arthroscopic anterior cruciate ligament reconstruction) according to 1:1. Follow-up knee function and other scores were performed at 3 months, 6 months, 1 year, and 2 years after surgery, and the total study time is expected to be 3 years.
