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.
In order to further observe the long-term safety and effectiveness of real-world polyethylene glycol-recombinant human growth hormone(PEG-rhGH) treatment of GHD, idiopathic short stature, and SGA in children, explore and analyze the factors affecting the efficacy of PEG-rhGH and the height prediction model after treatment, etc., collect and analyze more scientifically and rationally, and understand the situation of real-world PEG-GH treatment. A database registration study was developed.
The goal of this observational study is to compare the safety and effectiveness of a 3-steps standardized repair-oriented strategy with annuloplasty only in pediatric patients with mild to moderate mitral valve regurgitation. The main questions it aims to answer are: - Can 3-steps standardized repair-oriented strategy improve both left ventricular and mitral valve function in pediatric patients with mild to moderate mitral valve regurgitation? - Can surgical complications caused by the 3-steps standardized repair-oriented strategy be non-inferior (clinically acceptable) to annuloplasty only? Participants will be assigned to either the Standardized Group (including subvalvular apparatus rehabilitation (leaflet plication if chordae absent on leaflet margin, mal-connected chordae resection if chordae mal-connected to leaflet body, papillary muscle splitting if short chordae or dysplastic or fused papillary muscle etc.), leaflets repair (leaflets plication if functional leaflet prolapse, leaflet cleft closure and patch augmentation for anatomical leaflet defect, etc.) and annuloplasty (posterior annuloplasty for annular dilatation and shallow leaflet coaptation, etc.)) or the Annuloplasty Group (annuloplasty only during mitral repair surgeries. Additionally, echocardiography, electrocardiograms, and measurements of N-terminal pro-brain natriuretic peptide (NT-proBNP) were conducted before the initiation of surgery and at 1 months, 3 months, and 6 months after mitral repair. Researchers will compare the Standardized Group and the Annuloplasty Group to see if the recurrence rate of moderate to severe mitral valve regurgitation, as assessed by echocardiography after 6 months of surgery, is lower in the former than in the latter.
The goal of this observational study is to compare the safety and effectiveness of a modified drug therapy with traditional drug therapy in pediatric patients with mild to moderate mitral valve regurgitation. The main questions it aims to answer are: - Can a modified drug therapy improve both left ventricular and mitral valve function in pediatric patients with mild to moderate mitral valve regurgitation? - Can the adverse drug reactions caused by the modified drug therapy be non-inferior (clinically acceptable) to those of the traditional drug therapy? Participants will be assigned to either the Modified Drug Therapy Group (comprising angiotensin-converting enzyme inhibitor (ACE-I), beta-blockers, diuretics, potassium supplements, and spironolactone) or the Traditional Drug Therapy Group (diuretics and potassium supplements) based on personal preferences and clinical assessments by their attending physicians. They will undergo a one-year course of medication. Additionally, echocardiography, electrocardiograms, complete blood counts, biochemical tests, and measurements of N-terminal pro-brain natriuretic peptide (NT-proBNP) were conducted before the initiation of medication therapy and at 3 months, 6 months, and 12 months after treatment commencement. Researchers will compare the Modified Drug Therapy Group and the Traditional Drug Therapy Group to see if the recurrence rate of moderate to severe mitral valve regurgitation, as assessed by echocardiography after 12 months of treatment, is lower in the former than in the latter.
The study will be a prospective, randomized controlled trial comparing prostatic urethral lift (PUL) versus transurethral resection of prostate (TURP) in benign prostate hyperplasia (BPH) patients with urinary retention. The primary objective of this study is to compare the catheter-free rates of PUL vs TURP. Secondary objectives include comparison of complications rates, cost effectiveness, patient satisfactory, symptom scores, quality of life measures and urodynamic parameters.
Critically ill patients need reasonable and moderate analgesic and sedative treatment to eliminate or reduce pain, anxiety and restlessness, improve patient comfort and cooperation, reduce patients' stress response, protect organ function and optimize prognosis. As a semi-synthetic opioid receptor agonist-antagonist, nalbuphine can bind to μ, κand δ receptors, has partial antagonistic effect on μ receptor, and is fully activated on κreceptor, with very weak δ receptor activity. Results of a study on the efficacy and safety of nalbuphine for analgesia in ICU patients showed that nalbuphine has sustained and stable analgesic effect for patients with mild to moderate analgesic needs in ICU, the onset time is comparable to sufentanil, and excessive sedation caused by sufentanil can be avoided, and the effect on hemodynamics is small. It can be used as a new choice of analgesic drugs in ICU. A single-center, randomized, single-blind, prospective study was designed to compare nalbuphine and sufentanil in patients with ARDS after surgery. Sixty patients with ARDS after surgery to be admitted to ICU were randomly divided into experimental group (Nalbuphine group) and control group (Sufentanil group). This study aims to determine the analgesic efficacy and safety of nalbuphine hydrochloride in patients with Acute Respiratory distress syndrome (ARDS) after surgery. The successful development of this study will provide more theoretical basis for the individualized analgesic sedation program for surgical patients.
This is an open-label, single-arm, multicenter, phase Ib study to evaluate the efficacy and safety of SY-3505 capsule in patients with locally advanced or metastatic, LTK fusion-positive solid tumor who have progressed on or are intolerant to prior standard therapy.
HDAC inhibitor chidamide and PI3K inhibitor linperlisib has shown clinical activity as mono therapy in PTCL. The combination of duvelisib and romidepsin is highly active against relapsed and refractory T-cell lymphomas including cutaneous T-cell lymphomas (CTCLs). The aim of this study is to further explore the efficacy and safety of HDAC inhibitor chidamide combined with PI3K inhibitor linperlisib in the treatment of relapsed and refractory CTCLs.
This prospective, non-interventional study is designed to evaluate the quality of life of Chinese ovarian cancer patients with long-term niraparib use in a real-world setting. Participants will complete questionnaires or accept telephone follow-up to provide information about their quality of life.
The incidence of thyroid cancer has increased rapidly in recent years, especially in women. Early differentiated thyroid cancer has a good prognosis, and surgery is the main treatment. Traditional open surgery would leave a scar on the neck. However, emerging minimally invasive procedures can avoid the scar on the neck, resulting in better aesthetic effect, which would have an impact on the quality of life of patients to a certain degree. This study intend to follow up patients regularly with early differentiated thyroid cancer undergoing different surgery. The quality of life, voice, scar would be assessed by authoritative questionaires or scales. We hope to demonstrate that minimally invasive surgery is better than traditional open surgery in order to provide reliable evidence for clinical practice.
This is a Phase 1, open-label, dose-escalation study to evaluate the safety, PK, PD and immunogenicity of CC312 following intravenous doses of CC312 in patients with relapsed and refractory (r/r) CD19 expressing B-cell non-Hodgkin lymphoma and B-cell lymphocytic leukemia.
