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.
Dyspepsia is a very common gastrointestinal disease, presented as predominant symptom of upper abdominal pain. Underlying causes for dyspepsia can classified as organic or functional dyspepsia. Some medications (eg. non-steroid anti-inflammatory drugs (NSAIDs)) were associated with higher frequent incidences of organic lesions. Multiple medications showed an increased trend with aging of the population and multimorbidity. Multiple medications were suggested to be strongly relate to adverse drug events (ADEs), adverse drug reactions (ADRs), drug-drug interactions, and drug-disease interactions, which had been reported to lead to higher incidences of some diseases, including fractures, cognitive impairment and malnutrition. However, it was unknown if multiple medications was associated with more incidences of organic dyspepsia.
The purpose of this study is to evaluate the safety differences between intracranial support catheter and guide catheter for stent-assisted embolization in the treatment of unruptured intracranial aneurysms in the anterior circulation.
To investigate the efficacy and safety of carotid stenting for vulnerable carotid plaques. All patients with carotid artery stenosis underwent carotid arterial contrast-enhanced ultrasonography before operation. According to the examination results, they were divided into two groups: vulnerable plaque group and stable plaque group. The incidence of perioperative stroke events in the two groups was compared. The incidence of stroke events in the two groups within 1 year was compared.
This is a multicenter, single-arm, phase II clinical trial. The purpose of this study is to evaluate the efficacy and adverse effect of SBRT combined with programmed death 1 (PD-1) antibody and chemotherapy in nasopharyngeal carcinoma patients with oligometastasis.
This study is a case-control study. In this study, 2ml of vein blood samples were collected from patients with atrial fibrillation undergoing radiofrequency ablation and those in the control group who underwent electrophysiological examination alone and confirmed no arrhythmia. The purpose of this study is to identify the relationship between the aldehyde dehydrogenase 2 (ALDH2) gene polymorphism and susceptibility to atrial fibrillation, and to explore the relationship between the genotype of ALDH2 SNP and the prognosis of patients with atrial fibrillation undergoing radiofrequency ablation.
The purpose of this study is to assess the safety, tolerability and pharmacokinetics of ALMB-0166 in patients with acute spinal cord injury.
Concurrent chemoradiotherapy is the standard modality for locally advanced small-cell lung cancer, which could achieve median overall survival of 25 mos. Conventional fractionation of 66Gy/33f and hyperfractionation of 45Gy/30f twice daily have been acknowledged as the two standard radiotherapy modalities according to CONVERT study. In 2021, a phase II trial demonstrated that 60Gy/40f twice daily was superior to the standard 45Gy/30f twice daily in light of overall survival (2y OS 74.2% vs. 39% p=0.0005), which to some extent implied that higher dose may confer better survival. Hypofractionated radiotherapy was another useful modality to increase biological effective dose with the advantage of short course and convenience. The effectiveness and safety of 60Gy/15f has been demonstrated in the treatment of locally advanced non-small cell lung cancer. Therefore, this trial is designed to explore the safety and primary efficacy of hypofraction radiotherapy for stage III locally advanced small cell lung cancer.
The purpose of this study is to compare the clinical efficacy and economic cost of enucleation after placement of pancreatic duct stents before surgery with that of direct enucleation alone, and to evaluate its safety and feasibility.
To evaluate the safety and efficacy of Dasatinib plus CD19/CD22 Bispecific CAR-T for the treatment of elderly Ph-positive lymphoblastic leukemia. Newly diagnosed Ph-positive patients will be given Dasatinib plus VP chemotherapy for induction treatment,if a hematologic complete remission was observed then a lymphocyte collection will be administrated to patients. Then chemotherapy regimen of fludarabine and cyclophosphamide followed by a single infusion of CD19/CD22 CAR+ T cells
Establish a deep learning model based on multi-parameter magnetic resonance imaging to predict the efficacy of neoadjuvant therapy for locally advanced rectal cancer.This study intends to combine DCE with conventional MRI images for DL, establish a multi-parameter MRI model for predicting the efficacy of CRT, and compare it with the DL and non-artificial quantitative MRI diagnostic model constructed by conventional MRI to evaluate the role of DL in MRI predicting CRT. And this study also tries to build a DL platform to assess the efficacy of LARC neoadjuvant radiotherapy and chemotherapy, accurately assess patients' complete respose (pCR) after CRT, and provide an important basis for guiding clinical decision-making.
