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 goal of this observational study is to learn about in children aged 6-18 years, after the acute phase of SARS-CoV-2 infection, the COVID symptoms or Long COVID symptoms to impact their daily activities. We aimed to investigate the prevalence of long-lasting symptoms, the duration and intensity of symptoms, quality of life, number of sick days or absences from school, and psychological and social outcomes. The participants will be asked to fill in Long COVID symptom burden questionnaires who had been infected with SARS-CoV-2 as self-reported PRC test or antigen test positive.
The purpose of this clinical trial is to evaluate the effect of light-emitting diodes (LEDs) with a continuous spectrum of 430-780 nm for lighting in the classroom on myopia prevention among children in Grades 2 and 3.
The coprimary objectives of the study are to: - evaluate the efficacy of rocatinlimab in combination with topical corticosteroid and/or topical calcineurin inhibitor (TCS/TCI), compared with placebo in combination with TCS/TCI at Week 24, assessed using Validated Investigator's Global Assessment for Atopic Dermatitis (vIGA-AD™). - evaluate the efficacy of rocatinlimab, in combination with TCS/TCI, compared with placebo in combination with TCS/TCI at Week 24, assessed using Eczema Area and Severity Index (EASI).
This study is to assess the pharmacokinetics (PK) and safety of SC MK-3475A vs intravenous (IV) pembrolizumab, administered with chemotherapy in first line treatment of adult participants with metastatic non-small cell lung cancer. The primary hypotheses of this study are MK-3475A subcutaneous (SC) is noninferior to pembrolizumab IV with respect to PK parameters.
At present, there are few researches on peritoneal dialysis, especially on ultrafiltration failure of peritoneal dialysis. To explore the regularity and mechanism of peritoneal ultrafiltration failure,investigators followed up the comprehensive data of participants from the insertion to the removal of the peritoneal dialysis catheter, and collected the peritoneal tissue for morphological and single-cell analysis when the participants inserting or removing their catheters. If the catheter is still in use when this study stop collecting data, the peritoneal dialysis effluent will substitute for peritoneal tissue to the morphological and single-cell analysis. Clinical data and single-cell sequence data were processed using statistical analyses to identify factors affecting ultrafiltration failure.
Chronic postsurgical pain (CPSP) refers to pain that occurs or increases after surgery and lasts longer than 3 months. Severe postoperative acute pain is one of the major risk factors of CPSP. Spine surgery brings severe postoperative pain due to large trauma and long duration. Ketamine and esketamine are N-methyl-D-aspartate receptor antagonists; they have anti-hyperalgesic effects and may reduce CPSP. Dexmedetomidine is an alpha 2-adrenoceptor agonist with sedative, anxiolytic, and analgesic effect; it is frequently used as an adjuvant to postoperative analgesia. In a previous trial of the investigators, 200 patients following scoliosis correction surgery were randomzied to receive opioid analgsia supplemented with either mini-dose esketamine-dexmedetomidine combination or placebo. The results showed that esketamine-dexmedetomidine supplement analgesia significantly improved analgesia and sleep quality after surgery. This study is designed to test the hypothesis that mini-dose esketamine-dexmedetomidine supplemented analgesia may reduce CPSP at 2 years after scoliosis correction surgery.
Superficial cerebral veins findings in assessment of brain swelling in patients with aneurysmal subarachnoid hemorrhage who underwent intravenenous DSA examinations
This center intends to conduct a multicenter, randomized, placebo-controlled study to evaluate the effectiveness and safety of Nintedanib ethanesulfonate soft capsule in the treatment of pulmonary fibrosis in patients with moderate to severe COVID-19.
Flonoltinib Maleate as a JAK/FLT3 dual target inhibitor, previous pharmacological experiments showed that the IC50 inhibition of JAK2 kinase was as low as 0.8 nM, while the IC50 inhibition of JAK1, JAK3 and TYK2 kinases was 26 nM, 39 nM and 2 nM, respectively, and the IC50 of FLT3 kinase was 15 nM. It has high inhibitory activity for JAK2 kinase and good selectivity for JAK family.Multiple pharmacodynamic models evaluating the anti-inflammatory effect of Flonoltinib Maleate showed that Flonoltinib Maleate showed better therapeutic effect than the clinical drug Ruxolitinib with lower toxicity.
This is a Phase II, single-arm, multi-center clinical study to evaluate the anti-tumor efficacy, safety, tolerability and pharmacokinetics of DZD9008 in participants with locally advanced or metastatic NSCLC carrying EGFR exon 20 insertion mutations whose disease has progressed on prior platinum-based chemotherapy
