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.
To investigate the efficacy and safety of short-course radiotherapy sequential fruquintinib in combination with adebrelimab and CAPOX (full course neoadjuvant therapy) in patients with locally advanced rectal cancer.
This is a randomized, open-label study to evaluate the safety and efficacy of ZG005 in combination with Donafenib or Bevacizumab in patients with advanced hepatocellular carcinoma.
This is a single-center, single-arm, open-label study that includes patients meeting the inclusion criteria (liver-GTV volume < 700ml or estimated liver-GTV V5 < 300ml) with hepatocellular carcinoma with diffuse tumor thrombosis involving both left and right lobes. All lesions receive moderate-dose hypofractionated intensity-modulated radiotherapy, with a gross tumor dose of 25Gy/5f, and a maximum dose of 35Gy/5f at the tumor center. One week before or during the radiotherapy, patients receive concurrent Tislelizumab at a dose of 200mg. Subsequently, Tislelizumab is administered intravenously every 3 weeks. Follow-up examinations are conducted 1-3 months post-radiotherapy. Lenvatinib 4mg may be used for maintenance therapy with Tislelizumab if there are no contraindications. Maintenance therapy is continued until disease progression or intolerance. The primary endpoint is median overall survival (mOS), and secondary endpoints include objective response rate (ORR), progression-free survival (PFS), and toxicity.
- To quantitatively analyze the total radioactivity (TRA) in excrement after a single oral dose of [14C] D-1553 in healthy subjects, and obtain radioactivity recovery and primary excretion pathways in humans; - To obtain radioactive metabolite profiles of human plasma, urine and feces , identify major metabolites of D-1553 and determine the major metabolic pathways and elimination pathways; - To quantitatively analyze the TRA in whole blood and plasma and obtain PK parameters of plasma TRA and investigate whole blood/plasma ratio for TRA.
To evaluate the decreasing rate of blood IL-6, β2-MG and PTH in maintenance hemodialysis patients in the 52nd week compared with routine hemodialysis.
The most effective treatment for atlantoaxial dislocation is surgical treatment, with the principle of achieving reduction, reconstruction, and fusion of the atlantoaxial joint. The surgical strategies mainly include simple anterior approach, simple posterior approach, and combined anterior posterior approach. The investigators have summarized 904 cases of atlantoaxial instability or dislocation from 1998 to 2010 and preliminarily published the diagnosis and treatment strategy tree of the Third Hospital of Beijing Medical University. This strategy is divided into four types based on the severity of atlantoaxial dislocation: unstable, reversible, difficult to recover, and skeletal, and enters different surgical treatment processes. With the increase in the number of cases, accumulation of experience, and technological improvements in the past decade, spinal surgery colleagues have updated their classification diagnosis, diagnosis and treatment processes, and surgical techniques for atlantoaxial instability or dislocation. However, the selection of treatment strategies for atlantoaxial dislocation is mostly based on the surgeon's own experience, and there is a lack of standardized, large-scale, and high-level evidence-based medical research on the safety and effectiveness of current empirical strategies. Based on this, this study intends to adopt a multicenter, retrospective, and prospective study to construct a high-quality clinical cohort of atlantoaxial dislocation, update the classification and diagnosis and treatment strategies of atlantoaxial dislocation. And conduct long-term follow-up on patients to evaluate their safety and effectiveness, guide the surgical treatment of atlantoaxial dislocation, and thus form a recognized diagnostic and treatment standard for atlantoaxial dislocation.
Acute myeloid leukemia (AML) accounts for about 15% to 20% of childhood leukemia, but the death rate accounts for about 50%. About 20-30% of children with AML did not achieve complete response (CR) after 2 induction treatments, and about 30% of children with CR had relapse within 3 years (including recurrence after hematopoietic stem cell transplantation).Relapsed/refractory (R/R) AML is a major cause of treatment failure and refractory survival. Reinduction chemotherapy for R/R-AML to obtain CR again, followed by hematopoietic stem cell transplantation, is the current treatment. At present, there is no recognized reinduction protocol, and the reinduction remission rate of R/R-AML varies greatly among different treatment regimens, ranging from 23 to 81%. Current guidelines recommend a new combination chemotherapy regimen consisting of new drugs without cross-resistance. This method selects sensitive chemotherapeutic drugs, and then forms a new combination chemotherapy regimen according to the characteristics of drugs, which is the choice of R/R-AML reinduction therapy.This study intends to conduct a clinical study on the individualized treatment of R/R AML patients through in vitro drug sensitivity test combined with patient transcriptomic characteristics.
Crohn's disease (CD) is a long-lasting condition causing inflammation that can affect any part of the gut. The purpose of this study is to evaluate the efficacy and safety of TAK-279 versus placebo in participants with moderately to severely active Crohn's disease (CD). The main aim of this study is to learn if the 3 different doses of TAK-279 reduce bowel inflammation and ulcers in the bowel compared to the placebo after 12 weeks of treatment. Another aim is to compare any medical problems that participants have when they take TAK-279 or placebo and how well the participants tolerate any problems. An endoscopy will be used to check the bowel for inflammation. The participants will be treated with TAK-279 for 52 weeks (1 year). During the study, participants will visit their study clinic 15 times.t
The goal of this type of study to describe a new sandwich technique of minimally invasive keratoplasty (STMIK) by using SMILE-extracted lenticules for treatment corneal perforation and effectiveness. The main question[s] it aims to answer are: 1.Corneal perforations require urgent attendances for prompt treatments. How can we restore the integrity of the eyeball as soon as possible, reduce complications, and restore vision in the case of lack of corneal material according to the conditions that may be obtained. 2.In China, nearly 1 million lenticules are obtained through all-femtosecond surgery every year. How to reuse and turn waste into precious materials for clinical application is an important study. Participants will understand and signed the informed consent to take this new method for the treatment of their corneal perforations disease, which will obtain good results, but there may be a certain risk of complications.The main tasks participants will be asked to cooperate as required.The clinical eye check includes the test of includes visual acuity, slit lamp, anterior segment phase, anterior segment OCT and IOP.
Currently there are very few studies using wide-body detectors for 4DCT to determine lung tumor volume and comparing them with conventional detector 4DCT images, and no prospective clinical trials comparing 4DCT images from different width detectors have been queried, therefore, in this study, we will prospectively explore in a body model and patients: 1) the degree of artifacts, tumor volume, and radiation dose of the 4DCT scans performed by different width detectors. differences, and scanning radiation dose. (ii) Whether there are differences in different tumor ITV outlining modalities on 4DCT with different detector widths.
