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.
Dysphagia is an important complication in patients with medullary infarction, the incidence rate is 57%-69%. Compared with other brain infarctions, the medulla oblongata involves multiple swallowing-related nerve nuclei, and the possibility of brain remodeling after injury is small. Dysphagia has become a prominent clinical problem in patients with medullary infarction, which can lead to malnutrition, decrease the quality of life of patients and affect the prognosis of the disease. Solving this clinical problem is particularly important for patients with medullary infarction. The incidence of UES opening disorder in patients with medullary infarction is as high as 80%, and the clinical problem of UES opening disorder is enthusiastically studied at home and abroad. At present, the intervention measures include balloon dilatation, surgical incision and botulinum toxin injection. Balloon dilatation is easy to cause mucosal edema and damage, and cricopharyngeal myotomy often has complications such as local infection, massive hemorrhage and local nerve injury. There is no significant difference between the success rate of UES botulinum toxin injection and surgical incision. Among the above measures, UES botulinum toxin injection has a good clinical application prospect, but the drug dosage and injection method are still not unified in clinic. In particular, how to accurately locate has become a hot topic in current research. On this basis, this study uses ultrasound combined with balloon localization to inject UES botulinum toxin and make clinical observation.
The purpose of this study is to evaluate the PK effects of SHR4640 tablets on repaglinide and midazolam, as well as the effects of SHR4640 tablets on the QT interval in healthy subjects.
Gastric cancer is an important disease burden that threatens human health. Due to the complex biological characteristics of gastric cancer, the research on gastric cancer is still at a low level. Organoid technology is a breakthrough technology in cancer research. Gastric cancer organoid is a good model for gastric cancer research by three-dimensional culture of tumor cells in vitro, which simulates the spatial morphology and structure of tumors in vivo while preserving the biological characteristics of tumor cells. At present, gastric cancer organoid models have shown great advantages in many fields, such as the mechanism of gastric cancer development, tumor drug resistance, large-throughput chemotherapy drug screening, novel therapeutic target searching, and preclinical validation of novel drugs. In the current clinical trial, investigators cultured organoids from gastroscopic biopsy tissue of gastric cancer patients, and compared the organoids with the sampled tumors, including immunohistochemical indicators (Ki67+/CK20+/CDX2+), WES sequencing results. At the same time according to the guidelines. The recommended treatment plan is to compare the organoid model drug screening results with the clinical drug sensitivity.
The purpose of this study is to assess the effectiveness of acupuncture for treating catheter-related-bladder discomfort in adults after bladder outlet obstruction surgery.
This multicenter prospective cohort study aims to compare the difference in the effects of medical treatment within 1 year between the two groups of ICAS patients divided hemodynamically by Magnetic Resonance Fractional Flow Reserve. PC MRA will be applied for FFR measurement. The primary outcome is the composite of ischemic stroke or death related to the qualifying artery territory for 1 year.
The trial is a multicentre, prospective, open-label, blinded endpoint (PROBE), phase 3, randomized controlled design. Patients with acute ischemic stroke due to basilar artery occlusion presenting within 24 hours will be randomized 1:1 to intravenous tenecteplase (0.25mg/kg, maximum 25mg) ± thrombectomy or 'best practice'which may be alteplase (0.9mg/kg) within 4.5 hours from stroke onset or standard care (no lysis) ± thrombectomy at treating clinician's discretion.
Acute non-traumatic chest pain is one of the common causes of presentation in emergency patients, but the causes of acute non-traumatic chest pain are complex, the severity of the condition varies greatly, and the specificity of symptoms is not high. Machine learning and intelligent auxiliary models can greatly shorten the time of clinical decision-making, and improve the accuracy of etiological diagnosis in patients with chest pain, reduce the rate of misdiagnosis and missed diagnosis, and provide a clear direction for further treatment.
This is an open label, single-arm, Phase 2 study to evaluate the efficacy and safety of Anti-FcRL5 CAR-T in subjects with relapsed and refractory multiple myeloma. A leukapheresis procedure will be performed to manufacture. Anti-FcRL5 chimeric antigen receptor (CAR) modified T cells. Prior to Anti-FcRL5 infusion subjects will receive lymphodepleting therapy with fludarabine and cyclophosphamide.
Deep brain stimulation (DBS) is an effective treatment for a variety of neurological and psychiatric disorders, with more than 200,000 patients implanted with DBS devices worldwide. Parkinson's disease is one of the typical indications.The clinical outcomes of DBS depends on the accurate implantation of the lead, and the identification of the lead locations is the basis for evaluating the effectiveness of the treatment. The aim of this study is to localize the implantation position of the lead based on postoperative MRI images and to reconstruct the relative spatial relationship between the lead and the stimulation target. By comparing with the lead position identified based on postoperative CT, this study will evaluate the accuracy of identifying the DBS lead position directly from MRI. This study may help to optimise the stimulation parameters and investigate the best stimulation targets for DBS patients.
This is a Phase 2 randomized, double-blind, placebo-controlled, multicenter study evaluating the efficacy and safety of AK117 or placebo, combined with azacitidine in patients with newly diagnosed higher-risk myelodysplastic syndromes (HR-MDS).
