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 study is a further observation and follow-up of the patients enrolled in the registration number NCT04295330 to further evaluate the effect of long-term infusion of lidocaine on postoperative chronic pain, long-term quality of life and survival rate in patients undergoing liver cancer surgery.
This study plans to enrol 1000 participants 18 years and above, with ≥10% participants ≥60 years old. According to SARS-CoV-2 vaccine vaccination history, they will be evenly divided into 2 groups, Group A and Group B. Group A: will enrol 500 participants who have received 2 doses of inactivated SARS-CoV-2 vaccine according to national immunization planning, whose last dose was given at least 6 months ago. They will be given one dose of the study vaccine (SYS6006) after enrolment. Group B: will enrol 500 participants who have received 3 doses of inactivated SARS-CoV-2 vaccine according to national immunization planning, whose last dose was given at least 6 months ago. They will be given one dose of the study vaccine (SYS6006) after enrolment. The study is devided into two stages, the first stage will enrol 200 participants with 100 in Group A and 100 in Group B. They will undergo laboratory examination, immunogenicity observation and safety observation. The first 30 participants in each group will take extra cellular immune testing; the second stage will enrol the remaining 800 participants for safety observation.
The primary purpose of this clinical trial is to compare the effects of study medicine (Ponsegromab/PF-06946860) with a placebo (an injection that looks like the study medicine but does not contain the active medicine) to find out if the study medicine is better than the placebo (an injection that looks like the study medicine but does not contain the active medicine) for treatment of symptoms related to heart failure. Participants will not know which treatment group they are assigned to. Most participants in this study will receive the study medicine or placebo by shots under the skin every four weeks. People may be able to participate in this study if they have heart failure. Participants will take part in this study for about 9 months. During this time participants will visit the study clinic once a month. A separate PK cohort within this clinical trial will receive open-label study medicine (Ponsegromab/PF-06946860) only. Participants in this open-label, PK cohort will not receive placebo. These participants will receive the study medicine by shots under the skin every four weeks. People may be able to participate in this study cohort if they also have heart failure. Participants will take part in the open-label, PK cohort for about 7 months.
This is a Phase 1b/2 Study to Evaluate the Safety, Tolerability, Pharmacokinetics and Efficacy of D-1553 Combination Therapy in Subjects with KRAS G12C-mutated Locally Advanced or Metastatic Non-Small Cell Lung Cancer.
This is a prospective, single-arm, multicenter, phase II study to investigate the efficacy and safety of Ensartinib plus Bevacizumab in metastatic anaplastic lymphoma kinase (ALK)-rearranged Non-Small Cell Lung Cancer (NSCLC) with TP53 mutation.
Cataract is an important cause of blindness and visual impairment worldwide. At present, the only effective treatment method is surgery. The visual function of most patients can be significantly improved after surgery, but there are still 5-20% of patients whose visual function cannot be improved after surgery. Previous studies have found that the surgical complications and postoperative visual function of cataract patients are closely related to the condition of the fundus, but the current fundus camera cannot perform clear fundus imaging of cataract patients, and the existing potential visual inspections, such as retinal visual inspection, are also inaccurate. Predict postoperative visual acuity. Therefore, there is an urgent need for a reliable postoperative effect prediction system for cataract patients to provide reference for both ophthalmologists and patients. This study intends to collect patient medical record information and traditional/ultra-wide fundus photos and other multi-modal data. Firstly, this study will use artificial intelligence technology to enhance fundus photos of cataract patients to obtain clearer fundus photos. Then this study will use both medical record information and traditional/ultra-wide fundus photographs to predict postoperative vision and visual function of cataract patients.
Hemophagocytic lymphohistiocytosis (HLH) is a rapidly fatal disease caused by immune-dysregulation characterized by hypercytokinemia, with about 30%-40% of patients suffering death in children. Stratification strategy and individualized treatment is important to improve the survival. In our recent retrospective study, risk stratification based on IL-10 and IFN-γ levels well distinguished patients with different outcomes. In this multicenter prospective study, we will enroll the newly diagnosed pediatric HLH patients and divide them into low, intermediate and high-risk cytokine groups according to IFN-γ and IL-10 levels. The patients'clinical manifestation and laboratory findings will be further evaluated into severe and non-severe groups. For low/intermediate risk and non-severe patients, steroid or ruxolitinib will be used initially; while those with high risk or severe diseases, DXM+VP16±ruxolitinib will be administered. The treatment strategy could be adjusted after evaluation 48-72 hours later.
This is a single arm, multi-center study to evaluate the efficacy and safety of orelabrutinib for Chronic lymphocytic lymphoma（CLL)/small lymphocytic lymphoma (SLL) patients who are slowly responding to Ibrutinib switched to Orelabrutinib.
Angiogenesis is essential in tumor growth, proliferation, progression, and metastasis. Overexpression of aminopeptidase N (APN/CD13) and/or integrin αvβ3 in endothelial and tumor cells is an essential marker of tumor-associated angiogenesis. It is highly expressed in malignant tissues such as ovarian and pancreatic cancer but less expressed in normal tissues. Therefore, CD13 and αvβ3 are important targets for diagnosis and efficacy assessment in ovarian and pancreatic cancer. Single receptor targeting probes have many disadvantages, such as relatively low binding affinity, short tumor retention time, and low tumor uptake. RGD (Arg-Gly-Asp) and NGR (Asp-Gly-Arg) are recognized peptide sequences targeting CD13 or αvβ3. PET imaging with 68Ga-HX01, a radionuclide 68Ga labeled peptide isomer formed from RGD and NGR, can be helpful for targeted diagnosis and efficacy assessment of malignant tumors. This project proposes to use 68Ga-HX01 PET imaging in the diagnosis and staging of malignant tumors, i.e., ovarian and pancreatic cancer, and to compare the diagnostic efficacy of 68Ga-HX01 with the pathology gold standard. And this study was conducted to compensate for the lack of value of 18F-FDG PET imaging for the diagnosis and staging of malignant tumors by comparing 68Ga-HX01 with the commonly used 18F-FDG PET imaging.
The current standard for anemia screening, complete blood count, presents invasiveness, infrastructure requirements and high costs, leading to serious underestimation of anemia prevalence and insufficient care for anemia patients. Here, the investigators established and validated an artificial intelligence system to achieve automatic detection of anemia based on patient-sourced images of fingernails and conjunctivae. This system has been integrated into a smartphone app to be further validated through hospital-based and population-based clinical trials.
