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.
Allergic rhinitis (AR) is a non-infectious chronic inflammatory disease of the nasal mucosa mainly mediated by immunoglobulin E after exposure to allergens in atopic individuals. The typical symptoms of AR are paroxysmal sneezing, watery rhinorrhea, itching, and nasal congestion, which may be accompanied by ocular symptoms, including eye itching, tearing, redness, and burning sensation, which are more common in patients with hay fever allergies. Bronchial asthma is associated with bronchial asthma in 40% of patients with AR, suggesting a comorbid feature of allergic disease.
To assessed the current situation and outcome of critically ill patients with invasive aspergillus infection.
The early NSCLC（Non-small cell lung cancer） patients with partial solid nodules mainly composed of solid components, whose maximum tumor diameter was ≤ 2.0cm and 0.5<CTR（Consolidation tumor ratio）<1, as indicated by preoperative thin slice CT, were selected as the study objects. The short-term and long-term effects of segmental resection and lobectomy under Thoracoscopy were compared to provide high-level evidence for the selection of surgical treatment methods for early NSCLC.
This is a phase 1, first-in-human (FIH), open-label, multicohort study to evaluate the safety, tolerability and preliminary efficacy of CLL1 target CAR iPSC NK cells in patients with relapsed/refractory AML
The purpose of this trial was to investigate the safety and efficacy of fuser lateral bone grafting in ACDF. By observing the intervertebral bony fusion rate and clinical outcome scores of patients after fusion device lateral bone grafting, it was verified whether the fusion device lateral bone grafting approach could improve the bony fusion rate and clinical outcome of ACDF.
Acute kidney injury (AKI) is a common complication during the early postoperative period after noncardiac surgery. Patients with AKI are at an increased risk of developing chronic kidney disease, prolonging hospitalization, and experiencing higher rates of morbidity and mortality. Identifying preoperative risk factors for postoperative AKI can significantly contribute to the development of preventive strategies and improved perioperative care in this vulnerable patient population. The goal of this retrospective study is to investigate the predictive value of preoperative inflammatory status, as measured by complete blood count-derived inflammatory markers, such as the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), derived neutrophil-to-lymphocyte ratio (dNLR), neutrophil-to-lymphocyte*platelet ratio (NLPR), systemic immune-inflammatory index (SII), systemic inflammatory response index (SIRI), and aggregate index of systemic inflammation (AISI), on postoperative AKI in elderly patients undergoing non-cardiac surgery.
The Predictive Value of Clinical Data on Perioperative and Postoperative Risk Events in Patients With Head and Neck Artery Stenosis
Phase 1: Dose escalation study (Phase Ia) Main purpose: Evaluate the safety and tolerability of BIO-008 in patients with advanced solid tumors, and determine the maximum tolerable dose (MTD) and dose limiting toxicity (DLT) of BIO-008. Secondary purpose: Evaluate the pharmacokinetic (PK) characteristics of BIO-008; Evaluate the immunogenicity of BIO-008. Exploratory purposes: Preliminary evaluation of the anti-tumor activity of BIO-008 (if available); Detect the expression of CLDN18.2 in tumor tissue and explore its correlation with BIO-008 anti-tumor activity indicators (only applicable to subjects who can provide fresh or archived tumor tissue samples before the first administration). Phase 2: Dose Extension Study (Phase Ib) Main purpose: • Preliminary evaluation of ORR of BIO-008 in patients with CLDN18.2 positive advanced gastric cancer or gastroesophageal junction cancer (GC/GEJ), pancreatic cancer (PC) and other solid tumors; Determine the recommended dose for clinical phase II (RP2D). Secondary purpose: Evaluate the safety and tolerability of BIO-008; Evaluate the PK characteristics of BIO-008; Evaluate the immunogenicity of BIO-008; • Evaluate other anti-tumor activity indicators of BIO-008 in patients with CLDN18.2 positive advanced gastric cancer or gastroesophageal junction cancer, pancreatic cancer and other solid tumors; Evaluate the correlation between the anti-tumor activity of BIO-008 and the expression of CLDN18.2.
The goal of this clinical trial is to investigate the clinical efficacy of repetitive transcranial magnetic stimulation in the treatment of achalasia in patients diagnosed with achalasia by comprehensive evaluation of clinical symptoms, HREM, and barium meal examination, optimize rTMS treatment parameters, and provide an effective and noninvasive new treatment strategy for achalasia. The main questions it aims to answer are: 1. To investigate the clinical efficacy of individualized treatment of achalasia with optical 3D navigation repetitive transcranial magnetic stimulation. 2. Optimize rTMS parameters to achieve the best clinical treatment. Participants will need to fill out the Eckardt score scale and SF-36 quality of life scale, undergo cranial T1 structural magnetic resonance for functional connectivity analysis, and select the brain region with the strongest positive functional connectivity to the DMV as the rTMS target. All patients were randomly divided into four groups: sham-rTMS group, 5Hz-rTMS group, 10Hz-rTMS group, and 30Hz-rTMS group, and each group received acute and chronic stimulation, respectively. In the acute stimulation stage, patients only need to do rTMS once, and HREM and HRV detection are given before and after rTMS (stimulation for 1s, interval for 4s, 10 pulses per second, receiving a total of 3000 pulses); in the chronic stimulation stage, patients receive 25 minutes of rTMS actual stimulation or sham stimulation each time, lasting for 20 times, which is completed within 30 days, and the actual stimulation parameters are the same as those of acute stimulation, and the sham stimulation coil is consistent with the appearance and sound of proper stimulation, but there is no substantial stimulation. High-definition esophageal manometry, timed barium meal, heart rate coefficient of variation, and serum neurotransmitters were performed before and after chronic stimulation. Finally, a weekly telephone follow-up was performed for 12 weeks, including Eckardt score and SF-36 quality of life scale.
The objective of this study is to observe gastric mucosal injuries in NSAID and non-NSAID users with magnetically-controlled capsule gastroscopy, and explore the effects of NSAIDs on gastric mucosal damage.
