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 the study is to evaluate the long-term safety and tolerability of Brivaracetam (BRV) in focal epilepsy subjects with partial seizures and to evaluate the maintenance of efficacy of BRV over time.
This is a prospective case-control study on SAA patients treated with HSCT, order to further discuss and assess the safety, feasibility and effectiveness of HFD-HSCT which performed with reduced-intensity fludarabine-based conditioning regimen.Our findings would indicate that SAA patients who lack MSD benefited most if HFD-HSCT was performed with reduced-intensity fludarabine-based conditioning regimen, and our improved outcomes with HFD-HSCT may lead to a salvaged therapy and an expanded direct role for SAA in the future.
The investigators performed a multi-centered, randomized, placebo-controlled, prospective clinical trial on the effect of comprehensive rehabilitation program to improve quality of life(QOL) and long-term survival of postoperative patients with early lung cancer. The investigators plan to enroll 236 cases in 3 years (118 cases for rehabilitation training plus traditional Chinese medicine (TCM), 118 cases for rehabilitation education plus placebo), expecting that comprehensive rehabilitation program has a better efficacy on improving QOL and long-term survival.
This is a single-center, open-label, dose-escalating study to evaluate the safety, pharmacokinetics, immunogenicity, and preliminary efficacy of single dose subcutaneous injection of a fully human monoclonal antibody of receptor activator for nuclear factor-κ B ligand (RNAKL) (code name: TK006) in postmenopausal women.
Hepatitis A is the most prevalent hepatitis which account for approximately 45% . The susceptible population is Children and adolescence, also the morbidity in adult presented rising trend in recent years. Therefore, vaccination of Hepatitis A Vaccine play an important role in National Immunisation Program(China). The aim of this experiment is to verify the effects of experimental group non-inferior than control group. The experiment methods is compared the difference of seroconversion rate and Antibody geometric mean titer (GMT)between experimental and control Hepatitis A Vaccines. In addition, evaluating the safety of two Hepatitis A Vaccines in 18-24 months Chinese Children.
Liver diseases are worldwide problems. liver fibrosis and hepatocellular carcinoma are mostly concerned by clinicians. Radiomcis can improve diagnosis accuracy and evaluate disease progression. Hence,investors try to combine radiomics and ultrasound images together in order to improve diagnosis performances of liver fibrosis, benign and malignant tumor and progression after liver ablations.
In China, there's no effective prevention and treatment on preterm birth for pregnant women ≥35 years old, so this study is necessary.
There are always poor outcomes in patients with acute myocardial infarction(AMI) combined with elevated BNP/NT-proBNP level. An elevated BNP/NT-proBNP level highly indicates acute heart failure(AHF).Levosimendan is recommended in many clinical trials of heart failure and Chinese heart failure guidelines. As a result, the investigators form a hypothesis that when patients with AMI combined with elevated BNP/NT-proBNP level are in conditions before AHF, to use levosimendan may reduces the risk of heart failure and improve the outcome.
Mother-to-Child-Transmission (MTCT) of HBV is the most important route in high endemic countries. Although active-passive immune prophylaxis is generally administrated to infants delivered by HBsAg positive women, there are a lot of people infected with HBV in China. High HBV DNA load (>10^5IU/ml) is the vital cause of MTCT. So some researchers used TDF （tenofovir） or LDT（telbivudine） to treat patients with high HBV DNA load during middle, late pregnancy, in order to decrease MTCT. As a result, some data about it were gradually reported in late years. Recently, American Association for the Study of Liver Diseases, European Association for the Study of Liver Diseases and China guidelines for CHB (chronic hepatitis B) suggest that pregnant women with high HBV DNA load be treated with TDF or LDT at 24-28 weeks of gestation to lower MTCT of HBV. Although TDF or LDT is classified as pregnancy B drugs by FDA, and many studies report that MTCT rate of HBV decreases after women with high HBV DNA load are administrated with TDF or LDT at 24-28 weeks of gestation, a few birth defects are reported. Furthermore, the long-effect of TDF or LDT on infants remains unclear thoroughly. Some CHB women had severe liver dysfunction before pregnancy or during pregnancy, and routine liver protection therapy could not effect. Some of them could develop into liver failure, fibrosis, cirrhosis, and even died. Moreover, severe liver dysfunction often leads to adverse effects to pregnant women and fetuses, such as pregnancy failure, lower weight, premature birth, etc. As a result, these women have to accept TDF or LDT before pregnancy, or during early pregnancy. So the long-effect of TDF or LDT on infants needs thoroughly investigating. Taken together, the investigators will enroll women with chronic HBV infection and evaluate their state of illness. Then the investigators treat participants with TDF or LDT or routine liver protection therapy, and follow up the participants for a long period. The investigators' objectives are as follows: A, To clarify efficacy and adverse effects of TDF/LDT in preventing MTCT between immune-tolerant and immune-active CHB patients. B, To clarify efficacy and adverse effects of TDF/LDT in preventing MTCT during different trimesters of pregnancy. C, To compare MTCT rate between patients received TDF/LDT therapy and patients without TDF/LDT therapy. D, To compare MTCT rate and adverse effects between LDT and TDF.
It is universally accepted that the persistent infection of high-risk human papillomavirus(HR-HPV) is the cause of cervical intraepithelial neoplasias and cancer. Some researches indicate that the virus load may relate the extent of the disease. The objective of the study is to detect the virus load of 14 types HR-HPV among the participants, using a new HPV DNA hybrid capture technology,sequentially find the diagnostic significance of virus load of HPV.
