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.
Delirium is a common complication in elderly patients after surgery. And its occurrence is associated with worse outcomes. The causes of delirium are multifactorial but may include pain, stress response and inflammation. Dexamethasone is commonly used to prevent the occurrence of postoperative nausea and vomiting. In a randomized controlled trial, small-dose dexamethasone (8 mg) administered before anesthesia induction improved the quality of recovery in patients after cardiac surgery. Flurbiprofen axetil is commonly used to improve postoperative analgesia while decreasing the requirement of opioids. In a randomized trial of the investigators, combined use of flurbiprofen axetil with sufentanil for postoperative analgesia reduced delirium in elderly patients after orthopedic surgery. The purpose of this 2 plus 2 factorial randomized controlled trial is to test the hypothesis that combined use of dexamethasone and flurbiprofen axetil may reduce delirium in elderly patients after lung cancer surgery.
This study including two parts，one part is a randomized clinical trial design，another part is a registration study.
According to published studies, there are two main approaches in the dissection of intersegmental plane: stapling devices and energy instrument separation. However, only a few retrospective studies focused on the perioperative outcomes of these two approaches, and there has been no definitive conclusion about which method is better. So the investigators want to conduct a prospective study, trying to figure out this problem.
The study consists of the two parts, the first one is SHR7390 combined with SHR-1210, the second one is SHR7390 combined with SHR-1210 and SHR3162. Two parts of the study are separately to assess the safety and tolerability, to define dose limiting toxicity（DLT) and maximum tolerated dose (MTD),to evaluate the pharmacokinetics ,to assess the antitumor activity in patients with advanced solid tumors preliminarily and to recommend reasonable dosage regimen of SHR7390 for the follow-up clinical trial.
Surgical resection is the first choice treatment for patients with non-small-cell lung cancer. Despite of advances in surgical techniques, the long-term survival rate of postoperative patient is far from optimal. In a recent retrospective cohort study of the applicants, 588 patients after surgery for non-small-cell lung cancer were followed up for a medium of 5.2 years. The results showed that perioperative use of dexamethasone was associated with prolonged survival; perioperative use of flurbiprofen axetil was also associated with a slightly longer survival but not statistically significant. Further analysis showed that combined administration of dexamethasone and flurbiprofen axetil had additive effect in prolonging survival. We hypothesize that, for patients undergoing surgery for non-small-cell lung cancer, perioperative administration of dexamethasone and flurbiprofen axetil may improve long-term survival. However, evidences from randomized controlled trials are still lacking in this aspect.
The study will be conducted to compare the safety and efficacy of irinotecan combined with cisplatin (IP regimen) and etoposide combined with cisplatin (EP regimen) in advanced or metastatic gastrointestinal pancreatic and esophageal neuroendocrine carcinoma. In this prospective randomized phase II study, the investigators aim to compare the survival benefit as well as the safety for irinotecan combined with cisplatin (IP regimen) versus etoposide combined with cisplatin (EP regimen) in advanced or metastatic gastrointestinal pancreatic and esophageal neuroendocrine carcinoma.
Previous studies indicated that Granulocyte Macrophage-colony Stimulating Factor (GM-CSF) could improve survival rate in patients with acute liver failure and obtain higher HBsAg seroconversion rate when in combination with peg-interferon for chronic hepatitis B (CHB) patients. In this study, investigators will study the clinical effect of entecavir (ETV) plus GM-CSF in patients with CHB compared to ETV monotherapy.
Based upon biological behavior, those mCRC patients who respond well (SD, PR or CR according to RECIST Criteria) after 16-18 weeks of standard doublet chemotherapy as induction may enrolled into this study, randomly divided into capecitabine metronomic group or standard dosage group. The duration of disease control after randomization(PFS2) and progression free survival from enrollment (PFS1) are primary endpoints. Meanwhile, the overall survival, safety and quality of life are secondary endpoints. Exploratory markers involving angiogenesis (serum VEGF, PDGF, Tie-1 and Tie2, etc) and immune function (CD clusters, serum tumor mutation burden(TMB), etc), are conducted via liquid biopsy.
The purpose of this study is to determine the effects of CNP520 on cognition, global clinical status, and underlying AD pathology, as well as the safety of CNP520, in people at risk for the onset of clinical symptoms of AD based on their age, APOE genotype and elevated amyloid.
The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of CT053PTSA in Relapsed/refractory AML patients with FLT3 gene mutation.
