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 clinical trial is to evaluate the efficacy and safety of visual function training software (model: SJ-JRS2021) in the treatment of mild to moderate amblyopia in children. The main questions it aims to answer are: - Whether virtual reality training is more effective than occlusion therapy - Safety of virtual reality training in amblyopia treatment If participants have refractive problems, correct the refraction first and wear corrective glasses. The experimental group will be treated using visual function training therapy software (model: SJ-JRS2021). The control group will be treated with occlusion therapy covering the contralateral eye for 2 hours a day. Researchers will compare experimental group with control group to see if the experimental group has better corrected vision recovery.
This clinical study was mainly aimed at exploring the efficacy of herbal medicine (Huange Capsule) in the treatment of patients with prostatitis with elevated PSA. The main questions it aims to answer are: 1. To evaluate the influence and exact curative effect of huange capsule on serum PSA level of patients with PSA-elevated prostatitis, to improve the specificity of PSA and reduce unnecessary puncture biopsy. 2. To provide evidence-based evidence for clinical efficacy evaluation Subjects will be randomized to a routine regimen with or without the use of Huangge capsules. To evaluate whether the efficacy of the conventional treatment combined with Huange capsule group was superior to that of the conventional medication group.
The purpose of this clinical trial is to learn about the pharmacokinetics. safety and tolerability of the study medicine (called ARV-471) for the potential treatment of advanced estrogen receptor postive and human epidermal growth factor receptor 2 negative breast cancer. This study is seeking participants have - ER+/HER2- advanced breast cancer - received at least 1 line of endocrine therapy with or without CDK4/6 inhibitor - received up to 2 prior regimens of chemotherapy for advanced setting. All participants in this study will receive ARV-471. ARV-471 will be given by mouth at home once a day. The experiences of people receiving the study medicine will be examined. This will help determine if the study medicine is safe and effective. Participants will take part in this study until their cancer is no longer responding. During this time, they will have visits at the study clinic about every 4 weeks.
Preclinical data support the investigation of PARP inhibitors in other neoplasms exhibiting homologous recombination deficiency (HRD) as monotherapy as well as in combination with chemotherapy. However，in colorectal cancer (CRC), the role of HRD alterations is mostly unknown. This study aims to explore the the Efficacy and Safety of Fluzoparib combined with Irinotecan in the Second-line treatment of HRD alterations metastatic colorectal cancer.
The objective of this prospective cohort study is to explore the association between the development of post-traumatic stress disorder (PTSD) in surgeons and anesthesiologists and postoperative prognosis in surgical patients they care for during the COVID-19 pandemic. There are 2 cohorts included in this study. The first cohort consists of registered surgeons and anesthesiologists in the study center. The development of PTSD will be evaluated with a series of questionnaires and scales. This cohort defines exposure (with PTSD). The second cohort consists of surgical patients managed by the surgeons and anesthesiologists in the first cohort. The postoperative outcome of these patients will be evaluated thus to explore the association between PTSD in physicians and adverse patient outcomes. The second cohort defines the outcomes( response).
Although randomized trials have demonstrated there is no benefit of renal-artery stenting in addition to medical therapy for patients with atherosclerosis renal artery stenosis, many patients indeed gained benefit in daily practices after stenting, such as reduction in blood pressure and recovery in renal functions. One important gap is that there is no universal standard to determine whether to stent in these patients. Fraction Flow Reserve (FFR) has been studied for many year in chronic coronary heart disease and FFR-guided revascularization strategy is known to be better than both angiography-guided revascularization and medication alone. The goal of this clinical trial is to learn whether Fraction Flow Reserve (FFR) is appropriate to determine stenting in hypertension patients with atherosclerosis renal artery stenosis. The main questions it aims to answer are: - Is it appropriate to use FFR to determine whether or not stenting for hypertension patients with atherosclerosis renal artery stenosis? - To provide detailed data supporting design of further trial, such as sample size calculating, cut-off value for FFR in renal artery stenosis, etc. Participants met the inclusive/exclusive criteria will be randomized to stenting or not in the renal artery, then hyperemic FFR induced by dopamine will be measured in all participants. If FFR is ≥0.80, randomization will be applied. If FFR is <0.80, randomization will be ignored, and stenting will be performed as planned. The blood pressure and anti-hypertensive medications will be compared before and 3 months after the procedure based on ambulatory blood pressure monitoring, all participants will be followed up for 1 year.
Breast cancer patients often have sleep disturbances during the perioperative period. Dexmedetomidine is a highly selective alpha 2-adrenoceptor agonist with sedative, anxiolytic, and analgesic effects. Previous studies showed that night-time low-dose dexmedetomidine infusion improved sleep quality. Esketamine is a N-methyl-D-aspartic acid receptor antagonist and has been used as an anesthetic and analgesic. Recent studies showed that low-dose esketamine has anti-depressive and sleep-promoting effects. The investigators suppose that low-dose dexmedetomidine-esketamine combined nasal administration at night can improve perioperative sleep quality in patients scheduled for breast cancer surgery.
Open label, single- and multiple-dose administration, dose-exploratory clinical phase I study to evaluate the safety, tolerability and PK profile of HX301 monolactate capsules in patients with advanced malignant solid tumors and to preliminarily evaluate its antitumor efficacy.
This is the first in man study of E-SeaLATM developed and manufactured by Hangzhou Dinova EP Technology Co., Ltd, which can achieve pulsed field ablation and mechanical closure of the Left Atrial Appendage simultaneously, this study aims to initially verify the safety and efficacy of the device.
This is a multicenter, nonrandomized, open-label, parallel controlled Phase I clinical study to evaluate the Pharmacokinetics, Safety and Tolerability of SIM0417 combined with ritonavir after a single dose in subjects with mild and moderate renal impairment, moderate hepatic impairment, normal renal function, and normal hepatic function. It is divided into Part A (subjects with mild/moderate renal impairment and subjects with normal renal function) and Part B (subjects with moderate hepatic impairment and subjects with normal hepatic function).
