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.
This is a small-scale pre-clinical exploratory study to investigate the safety of a novel single-port robotic system for general surgery.
This study is a multicenter, randomized, double-blind study. There are three dosage groups: Hemay005 45 mg BID group, 60 mg BID group or placebo group, with 36 patients in each dosage group. All patients will enter a 12-week double-blind treatment period. All subjects who have received the investigational drug should be subjected to a 4-week observation after the end of treatment.
80% of patients with mantle cell lymphoma (mantle cell lymphoma, MCL)were in the advanced tumor stage when they were first diagnosed. Zabutinib, as a new generation of BTK inhibitors, has better targeting and safety in clinical application. Previous studies have confirmed that zabutinib has good efficacy in treating relapsed refractory MCL. However, for patients with a high risk of drug resistance to BTK inhibitors or patients with drug resistance, the efficacy of BTK inhibitors alone is poor, and combined therapy can improve the poor prognosis of these patients. Therefore, the primary purpose of this study is to evaluate the safety and efficacy of zebutenil in treating recurrent, refractory mantle cell lymphoma.
This trial is a prospective, multicenter, single-group target-value clinical trial in which patients with chronic left heart failure are planned to be recruited. Using the atrial shunt implantation system developed and produced by Morningside (Nantong) Medical Device Co., Ltd., the atrial septum is used to implant the instruments in the atrial septum. to verify the safety and efficacy of the atrial shunt implant system for the treatment of patients with chronic left heart failure.
The incidence of colorectal cancer liver metastasis is high and the prognosis is poor. Improving the treatment effect of colorectal cancer liver metastasis is the key to improving the prognosis of colorectal cancer patients. Rigofenib is one of the standard third-line treatments for advanced colorectal cancer, but has limited efficacy. Immune checkpoint inhibitors (PD-L1 monoclonal antibody, PD-1 monoclonal antibody) have achieved good results in the treatment of various malignant tumors. In a mouse transplant tumor model of colorectal cancer, regorafenib combined with PD-1 monoclonal antibody treatment significantly improved the antitumor activity, but the efficacy rate in clinical studies was not very high, especially for liver metastases. Radiofrequency ablation (RFA) is one of the common methods for the treatment of liver metastases. RFA may improve the immune microenvironment and the efficacy of immunotherapy,and the purpose of this trial is to explore the efficacy and safety of rigofenib and terepliumab combined with RFA in patients with refractory colorectal cancer liver metastasis.
This is a phase II study to determine the efficacy and safety of Pembrolizumab when given in combination with Lenvatinib as treatment for patients with the advanced kidney cancer. Further evaluate whether the treatment plan is beneficial to the patient's operation. Patients will receive treatment with Pembrolizumab in combination with Lenvatinib every 3 weeks for 3 cycles pre-operation and patients need to continue taking the drug for a year after surgery.
This is a phase II study to determine the efficacy and safety of Tislelizumab when given in combination with Lenvatinib as treatment for patients with the advanced kidney cancer . Patients will receive treatment with Tislelizumab in combination with Lenvatinib every 3 weeks unitl tumor progression or serious side effects
Identify the pathogenic factors involved in the occurrence and development of panvascular disease and its pathogenesis.
In this study, the safety and preliminary efficacy of GNC-038 in patients with r relapsed or refractory primary central nervous system lymphoma (PCNSL) and relapsed or refractory secondary central nervous system lymphoma (SCNSL) will be investigated to assess the dose-limiting toxicity (DLT), maximum tolerated dose (MTD) or maximum administered dose (MAD) for MTD is not reached of GNC-038. The recommended dose for phase II (RP2D) clinical study will also be determined.
This is a retrospective, observational multi-center study. The participants undergone lumbar spine surgery for degenerative lumbar scoliosis and followed up for at least 2 years are retrospectively enrolled from 8 centers. This study mainly focuses on the short-term and long-term outcomes of lumbar surgery in participants with degenerative lumbar scoliosis, and that how much the surgical outcomes are related with demographic, surgical, and radiographic features before and after surgery. The objective is to offer more detailed clinical evidence to guide the surgical strategy development for degenerative lumbar scoliosis.
