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 aim of the study is to collect real world information on patients with locally advanced or metastatic non small cell lung cancer (NSCLC) who progressed after first line treatment with an approved Tyrosine-Kinase Inhibitor (TKI), who are known to be T790M positive and have been prescribed second line platinum-based chemotherapy (Pemetrexed + Cisplatin /Carboplatin).
It's to investigate the efficacy of Zoledronic acid treatment on the early prosthetic fixation in post-menopausal osteoporosis women under cementless total hip arthroplasty after 24-month observation.
Background: Repeated episodes of bleeding from gastrointestinal vascular malformations refractory to endoscopic or surgical therapy often pose a major therapeutic challenge. Methods: The investigators will perform a randomized, double blind, placebo controlled study of thalidomide as a retreatment therapy for recurrent gastrointestinal bleeding due to vascular malformation. Patients with failure of first course treatment of thalidomide will be randomly grouped, prescribed a second four-month course regimen of 25 mg of thalidomide or placebo orally four times daily. All patients will be monitored for at least one year. The primary end point is defined as the patients whose rebleeds decrease from baseline by ≥ 50% at 12 months and the cessation of bleeding. Rebleeding is defined based on a positive fecal occult blood test (FOBT) (monoclonal colloidal gold color technology) at any visit after treatment. Secondary outcomes include the participants dependent on blood transfusions and changes from baseline in transfused packed red cell units, bleeding episodes, and hemoglobin levels at 12 months. Statistical significance is defined at P < 0.05.
Currently, concurrent chemoradiotherapy with/without sequential chemotherapy is the standard treatment modality for intermediate risk NPC (stage II and T3N0M0) according to the National Comprehensive Cancer Network guideline. However these recommendations were based on the evidence in the two-dimensional conventional radiotherapy (2DCRT) era. The introduction of intensity-modulated radiotherapy (IMRT) in NPC treatment has brought substantial better treatment outcomes than 2DCRT. It has been questioned whether additional concurrent chemotherapy is still necessary for intermediate risk NPC within the excellent framework of IMRT. hus, we jointly conduct the first non-inferior randomized trial to determine the value of concurrent chemotherapy with cisplatin for intermediate risk NPC patients treated with IMRT. Given the results of clinical studies mentioned above, we decide to adopt the concurrent regimen to be cisplatin 100 mg/m2 on day 1, 22, 43
Esophageal cancer is one of common malignant tumors in China and esophageal squamous cell carcinoma (ESCC) is the dominant pathological type, accounting for more than 95% of all cases. One of our phase Ⅱ study introduced a combination treatment of an anti epithelial growth factor receptor (EGFR) agent, nimotuzumab, with paclitaxel and cisplatin as first-line treatment in unresectable or metastatic ESCC. The results showed that the overall response rate was 51.8% (29/56) and disease control rate was 92.9% (52/56). As a median follow-up of 24 months, the median progression-free survival for patients with metastatic disease and local advanced disease were 8.2 months and more than 23 months respectively. The overall survival for patients with metastatic disease was 13.9 months. It implied that as first-line chemotherapy, an addition of nimotuzumab to chemotherapy was a more active treatment option compared to other regimens published in previous studies. Investigations by Liang, J. and Ling, Y. also suggested that nimotuzumab in combining with radiotherapy or chemotherapy also showed anti-tumor activities and limited toxicities. Therefore, we initiated this phase Ⅱ to Ⅲ clinical trial in which combining neoadjuvant treatments of nimotuzumab with chemotherapy or nimotuzumab with radiotherapy are compared with surgery alone for resectable stage Ⅱa to Ⅲ middle and lower thoracic esophageal squamous cell carcinoma patients. We hope to explore if these neoadjuvant combination treatments could bring survival benefit for ESCC patients.
The project was undertaking by Qilu Hospital of Shandong University and other 5 well-known hospitals in China. In order to report the efficacy and safety of recombinant human thrombopoietin combining with cyclosporin A for the treatment of adults with refractory immune thrombocytopenia (ITP), compared to cyclosporin A monotherapy.
This prospective randomized double-blinded study was conducted to compare the antishivering effects of two different types of intrathecal administration.
China Rural Hypertension Control (CRHC) Project is a cluster randomized trial aims to test the effectiveness of a standardized protocol-based treatment program on hypertension control in rural China.
The purpose of this study is to determine whether TACE combined endovascular stent implantation confers a survival benefit over TACE alone.
This study was performed in 131 adult patients undergoing transurethral, urological or lower limb surgery under combined spinal and epidural anesthesia. Patients were stratified according to age: 20-30, 31-40, 41-50, 51-60, 61-70, and 71-80 years. The spinal component of the anesthetic was established by bolus administration of up-and-down doses of 0.75% plain bupivacaine, determined by Dixon's method. The degree of motor block after intrathecal administration of each concentration was evaluated by the modified Bromage and Hip motor function score. The EC50 were estimated from the up-and-down sequences using the method of Dixon and Massey and logistic regression. Other endpoints were included on the basis of sensory block level, duration of motor blockade, hypotension, and vasopressor requirements.
