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 treatment of helicobacter pylori is very important. The routine treatment is quadruple therapy. In recent years, double therapy has appeared and the curative effect is fair. However, antacid generally uses proton pump inhibitor. The proton pump inhibitor needs double dose to achieve good antacid curative effect. The effect of vonoprazan used for inhibiting gastric acid is better than proton pump inhibitor. At present, many studies use vonoprazan instead of common proton pump inhibitor, but almost all use double dose of vonoprazan. In the previous study, we found that the effect of double dose of proton pump inhibitor can be achieved with 20mg QD of vonoprazan. Therefore, in this study, 20mg QD of vonoprazan was used to replace the double dose of proton pump inhibitor to observe the antibacterial effect of vonoprazan on Helicobacter pylori.
The primary objective of this study is to estimate the efficacy of Relmacabtagene Autoleucel in participants with high-risk large B-cell lymphoma.
The primary objective of this study is to evaluate the safety of an innovative integrated treatment regimen for recurrent glioblastoma , including patients with recurrent glioblastoma multiforme.
In recent years, the number of people with symptoms of depression or anxiety are on the rise. The aims of the prospective randomized study are: (1) to examine the effects of Baduanjin breathing training on reducing symptoms of depression or anxiety, and (2) to explore the correlates between improvements of depression or anxiety symptom and changes of lung functions.
The goal of this observational study is to establish a preoperative imaging diagnostic model which highly consistent with the histopathological examinations, as well as a accurate and systematic pathological grading standard of inferior vena cava (IVC) vascular wall invasion in renal cell carcinoma (RCC) with tumor thrombus invading vascular wall.The main questions it aims to answer are: - To establish a preoperative imaging diagnostic model which highly consistent with the histopathological examinations. - To determine what impact does different vascular wall layer invasion make on the long-term prognosis in RCC with IVC tumor thrombus; - To determine which layer invasion according to pathological examination make sense to clinical treatment (can significantly affect prognosis); Participants with IVC vascular wall invasion/ non-invasion are divided into experimental group (invaded group) or control group (non-invaded group) respectively according to pathological examinations, in order to establish a prospective cohort with three-year follow-up. The pathological characteristics of local recurrence and poor prognosis are summarized, and postoperative pathological diagnostic criteria of IVC vascular wall invasion and established. The local recurrence and distant recurrence outcomes are compared between experiment group and control group, in order to analyze the long-term influence of vascular wall invasion. Then the preoperative imaging diagnostic evaluation model will be established.
Assessment of aging is central to health management. Compared to chronological age, biological age can better reflect the aging process and health status; however, an effective indicator of biological age in clinical practice is lacking. Human lens accumulates biological changes during aging and is amenable to a rapid and objective assessment. Therefore, the investigators will develop LensAge as an innovative indicator to reveal biological age based on deep learning using lens photographs.
The purpose of this study is to determine the target dose of phase II and to evaluate the safety, tolerability, pharmacokinetics and efficacy of recombinant anti-IL-1β humanized monoclonal antibody injection at different doses in Chinese participants with acute gout.
This is a randomized, double-blind, placebo controlled, dose-ranging Phase 2 study. The primary objective is to evaluate the efficacy and safety of SAR443122 compared to placebo in participants with moderate to severe UC. Dose selection for further clinical development will be based on the multiple efficacy, safety and PK parameters. The study consists of 4 parallel arms (3 dose groups of SAR443122 vs placebo) to assess the efficacy and safety of SAR443122 in participants with moderate to severe UC. All participants will receive a total of 52 weeks (a 12-week induction treatment phase and a 40-week maintenance phase) of study treatment, except if treatment should be discontinued per investigator's assessment. At the end of the first 12 weeks of induction treatment, all participants in clinical response or remission will be offered study treatment up to 40 weeks and will continue with the same blinded treatment that was assigned. Participants who do not achieve clinical response or remission at the end of the initial 12 weeks induction treatment will roll over in an open-label treatment arm and will be treated with SAR443122 at the highest tested dose. In addition, participants from the maintenance treatment that lose clinical efficacy at any time up to V10/Week 40 (Week 28 of maintenance) will be offered to roll over in the open-label treatment arm with SAR443122 at the highest dose.
Pediatric population is at a high-risk of pressure injury (PI). Patients undergoing liver transplantation are more prone to PIs compared with other types of surgery. However, there is a lack of sensitive and specific assessment tools for the risk of PI in patients undergoing liver transplantation. How to accurately predict the incidence of PI in patients undergoing liver transplantation is needs to be urgently eliminated. The study is conducted in the Renji Hospital, School of Medicine, Shanghai Jiaotong University which is the largest liver transplantation center in China.
This study aims to evaluate the efficacy and safety of Tislelizumab combined with concurrent chemoradiotherapy in the treatment of cervical cancer patients with cervical mass > 4cm and regional lymph node metastasis, paracervical invasion and regional lymph node metastasis, stage IIIA, stage IIIB, and stage IVA. To provide a clinical reference for finding a safe and effective individualized treatment plan to improve the survival prognosis of locally advanced cervical cancer patients.
