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.
Our project is going to clarify the efficacy and safety of Toripalimab in lung cancer in the real world, and to evaluate the incidence of adverse events (AEs) of special interest during Toripalimab immunotherapy.
This research group plans to take patients with mild to moderate UC and diarrhea IBS diagnosed in the First Affiliated Hospital of Xinxiang Medical College as examples, and divide them into UC group and IBS group; Each group was randomly divided into two groups, namely, conventional treatment+probiotics group and conventional treatment+probiotics placebo group.Starting from the intervention of probiotics on intestinal flora to alleviate intestinal injury caused by UC and IBS patients, the indicators of intestinal flora, serum inflammatory factors, metabolites in vivo, intestinal barrier-related protein expression, and fecal short-chain fatty acid level were detected to explore the clinical efficacy, intestinal protective effect and mechanism of probiotics in adjuvant treatment of UC and IBS patients.To provide new methods and new ideas for refractory UC and IBS, so as to improve the cure rate of UC and IBS, reduce the recurrence rate, relieve the physical and mental pain and economic burden of patients, and provide new ideas for the development and utilization of functional probiotics. It also seeks biosafety evidence for the future use of probiotics in antibiotic environment.
The goal of this clinical trial is to study of the Safety and Efficacy of Chimeric Antigen Receptor NK Cell Injection Targeting BCMA (BCMA CAR-NK) in Patients with Relapsed/Refractory Multiple Myeloma Primary Endpoints: To evaluate the safety and tolerability of patients with relapsed/refractory multiple myeloma (RR/MM) after BCMA CAR-NK infusion. To determine the maximum tolerated dose (MTD) and/or subsequent recommended dose (RD) of BCMA CAR-NK in patients with RR/MM. Secondary Endpoints: To preliminarily evaluate the effectiveness of BCMA CAR-NK in patients with RR/MM. To preliminarily evaluate the pharmacokinetic parameters of BCMA CAR-NK cells in patients with RR/MM. To preliminarily evaluate BCMA CAR-NK cell survival in subjects blood in relation to efficacy, adverse events and relevant biomarker levels. To preliminarily evaluate the relationship between donors and subjects KIR-Ligand mismatch and safety & efficacy. To preliminarily evaluate the impact of the degree of HLA genotype matching between donors and subjects on the survival of BCMA CAR-NK cells in the subjects blood. Subjects are enrolled and treated with lymphocyte clearance chemotherapy (including pre-clearance evaluation), pre-infusion evaluation and BCMA CAR-NK cells infusion and enter the follow-up period after the end of the DLT observation period.
The study is a prospective, randomized, single-blind clinical trial aiming to compare two method in guidance of Vein of Marshall ethanol infusion (VOMEI), i.e., the conventional fluoroscopy-guided VOMEI and UNIVU-guided VOMEI.
Radiotherapy and immunotherapy have achieved good survival benefit in advanced nasopharyngeal carcinoma. A number of clinical studies of immunotherapy combined with radiotherapy for nasopharyngeal carcinoma are also ongoing. This study preliminarily explored the efficacy and safety of SBRT combined with tislelizumab and chemotherapy in metastatic nasopharyngeal carcinoma. Hypofractionated radiotherapy combine with systemic chemotherapy and immunotherapy in advanced nasopharyngeal carcinoma. Not only it can achieve rapid response of distant metastases, but also to achieve long-term survival benefit for patients, which provides the reference for subsequent studies.
The primary purpose of this clinical trial is to evaluate the efficacy and safety of the transcatheter aortic valve system in the treatment of patients with failing bioprosthetic valve
1. To observe and measure the distance between the origin of LCA (left colonic artery，LCA) and IMA (inferior mesenteric artery，IMA) root and the distance between IMA and IMV (inferior mesenteric vein，IMV) at the origin of LCA in rectal cancer patients. Statistical analysis of intraoperative measured data, on the basis of the original anatomical relationship, to achieve anatomical localization of quantitative and accurate, for the preservation of LCA laparoscopic radical resection of rectal cancer to provide a strong anatomical basis. 2. The operation time, 253 lymph node dissection time, intraoperative blood loss, postoperative anal exhaust time, postoperative feeding time, postoperative hospital stay, postoperative ischemic colitis rate and postoperative anastomotic leakage rate of patients with laparoscopic radical resection of rectal cancer with preservation of LCA were recorded. The surgical efficacy and clinical significance of laparoscopic radical resection of rectal cancer with preservation of LCA were evaluated.
The incidence of colorectal cancer in China is increasing year by year. Studies have shown that colorectal cancer is more common in the left colon，especially in the China. Our previous study also showed a higher rate of missed adenoma in the left colon than the right colon during colonoscopy. Additionally, prolonging withdrawal time could only improve the ADR of right colon, but had limited effect on the ADR of left colon in our previous research. Our aim is to evaluate the effect of a second forward view examination of the left colon on the detection of adenoma detection during colonoscopy.
This is a future-proof and randomized controlled clinical study on the clinical efficacy of graphene photothermal adjuvant therapy in Corona Virus Disease 2019(COVID-19) patients with mild symptoms. The objective is to examine the effect of graphene photothermal adjuvant therapy on the time line for such Corona Virus Disease 2019 patients to achieve a negative severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) nucleic acid test result, and their duration of disease. Patients who meet study criteria will be randomized into the Grapheme adjuvant therapy combined with conventional therapy group (treatment group) and the conventional therapy only group (control group). Contrasted to the control groups, the treatment groups will undergo 30-min of graphene adjuvant therapy every day for 7 d.
At present, prophylactic cranial irradiation (PCI) is part of standard care for patients with limited-stage small cell lung cancer (SCLC) who have achieved good response after definitive thoracic radiotherapy and chemotherapy. However, the value of PCI is being challenged in the era when MRI examination of brain has been popularized. The goal of this clinical study is to compare PCI and regular brain MRI follow-up (control arm) and regular brain MRI follow-up alone (study arm) in patients with limited-stage SCLC who have received definitive radiotherapy and chemotherapy and acheived complete remission (CR) of tumor. The main questions to answer are: 1. Whether the 2-year brain metastasis-free survival rate of the study group is not inferior to that of the control group. 2. The difference of 2-year overall survival rate between the control group and the study group. 3. Whether the patients in the study group have better overall quality of life than those in the control group. Participants will randomly receive either PCI and regular brain MRI follow-up or regular brain MRI follow-up alone.
