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 current measurement methods of strabismus include the corneal light reflection method, prism alternate covering, etc., which especially rely on the subjective experience of doctors, and there is a large error between different measurers， leading to serious underestimation of strabismus prevalence and insufficient care for strabismus patients. Here, the investigators established and validated an artificial intelligence system to achieve an automatic diagnosis of strabismus based on patient-sourced videos of programmatic cover tests. Three-dimensional reconstruction methods are used to digitize the parameters of head and eye positions. This system has been integrated into a smartphone platform to be further validated through hospital-based and population-based clinical trials.
This pilot phase I trial aims to investigate the safety and tolerability of low dose radiotherapy (LDRT) and concurrent partial stereotactic body radiation therapy (SBRT) in combination with programmed cell death-1 (PD-1) inhibitors in Stage IV non-small cell lung cancer (NSCLC) patients who have failed standard therapy. At least 9 participants will be enrolled in this study. All will take part at West China Hospital, Sichuan University.
Treatment with immune checkpoint inhibitors such as programmed death receptor 1 (PD-1 inhibitors) for advanced and metastatic esophageal squamous cell carcinoma (ESCC) significantly improves patients' overall survival compared to chemotherapy alone. Despite this milestone breakthrough, immunochemotherapy also has known limitations. Indeed, only 45-72% of patients achieved objective responses. It is urgent to find out easily-determined and convenient biomarkers to identify patients who will benefit from such treatment modality. Due to the luminal structure of the esophagus, the exact diameter of esophageal tumor cannot be precisely measured per RECIST 1.1. Moreover, the definition of the metastatic lymph node in which the short-axis lengths should be longer than 1.5 cm hinders the risk of missing the smaller metastatic lymph node foci. Thus, it is difficult to implement morphology-based criteria for evaluating the neoadjuvant immunochemotherapy response. The current study aimed to investigate the role of iPERCIST in predicting tumor response and the short-term overall survival of patients with locally advanced ESCC after neoadjuvant immunochemotherapy.
Compare the effectiveness and safety of contact aspiration (CA) and stent retriever (SR) in acute ischemic stroke patients with basilar artery occlusion.
The main purpose of this study is to learn more about the safety, side effects, and effectiveness of LOXO-435. LOXO-435 may be used to treat cancer of the cells that line the urinary system and other solid tumor cancers that have a change in a particular gene (known as the FGFR3 gene). Participation could last up to 30 months (2.5 years) and possibly longer if the disease does not get worse.
The purpose of this trial is to evaluate safety and efficacy of intravenous delivery of EXG001-307 as a treatment of spinal muscular atrophy Type 1 (SMN1).
Soft tissue sarcoma (STS) refers to a group of malignant tumors derived from non-epithelial extraosseous tissues, mainly from the mesoderm, partly from the neuroectoderm, including muscle, fat, fibrous tissue, blood vessels and peripheral nerves . STS is divided into 12 major categories based on tissue origin. According to different morphologies and biological behaviors, there are more than 50 subtypes. The most common subtypes include: undifferentiated pleomorphic sarcoma (UPS), liposarcoma (LPS), leiomyosarcoma (LMS), synovial sarcoma ( SS). The most common soft tissue sarcoma in children and adolescents is rhabdomyosarcoma (RMS). Soft tissue sarcoma is a group of highly heterogeneous tumors, which are characterized by local invasiveness, invasive or destructive growth, local recurrence and distant metastasis. The pathological features of STS that occur in the nasal cavity and sinuses are similar to other parts of the body. However, because it can affect important structures such as the orbit, optic nerve, skull base bone, dura mater, cranial nerve and even brain tissue, the diseased site is deep, the anatomical structure is complex, the treatment is difficult, the range of surgical resection is limited, and the surgical margin Negative is difficult to guarantee, and related treatments may have obvious complications, which affect the survival and prognosis of patients. Surgical treatment is the most important and most likely effective treatment for STS. With the development of endoscopic skull base anatomy and surgical techniques, the safety and effectiveness of endoscopic sinus surgery for the treatment of nasal cavity and sinus tumors have been fully confirmed, and it has become the main surgical method for nasal cavity and sinus STS. This is also the theoretical and practical basis for the feasibility of this research. The study intends to conduct a single-arm, prospective, observational study of endoscopic sinus surgery for the treatment of soft tissue sarcoma of the nasal cavity and paranasal sinuses to explore the therapeutic effect and complications of endoscopic surgery for the treatment of soft tissue sarcoma of the nasal cavity and paranasal sinuses, and explore its relationship with chemotherapy and radiotherapy. The model of comprehensive treatment between.
To investigate the performance of enhanced computed tomography (CT) or magnetic resonance (MR) imaging by deep learning relative to conventional CT or MR imaging in brain stroke and vascular neurology. We expect that the deep enhanced imaging method can shorten the time stay in the imaging session of stroke patients, optimize the overall imaging quality and improve the patients' care in imaging session.
This registry will include consecutive patients presenting with at least one chronic total occlusion on coronary angiogram who will be treated by percutaneous coronary intervention in our center. All patients will undergo a non-invasive assessment for myocardial ischemia/viability using cardiac magnetic resonance (CMR) prior to revascularization therapy. Follow up CMR will be repeated in all participants after three months and one year. Additionally, clinical outcomes and quality of life will be evaluated at baseline and at follow-up. Primary objective of this study is to investigate the the reduction in ischemia (as evaluated by follow-up CMR) and the severity of angina according to clinical evaluation (including Seattle Angina Questionnaires [SAQ], Canadian Class Score[CCS] and 6-mins walking test).
Researchers are looking for a better way to treat people who have advanced solid tumors. Advanced solid tumors are types of cancer that may have spread to nearby tissue, lymph nodes, and/or to distant parts of the body and that are unlikely to be cured or controlled with currently available treatments. This study focuses on certain types of skin cancer, kidney cancer, stomach cancer, and lung cancer. The study treatment BAY2965501 is currently under development as monotherapy or in combination with a drug named pembrolizumab for the treatment of people with advanced solid tumors. BAY2965501 blocks an enzyme in T-cells to activate them. T-cells are a type of immune cell that are known to have an anti-cancer effect and BAY2965501 is a potential new immunotherapy. The main purpose of this first-in-human study is to learn: - how safe different doses of BAY2965501 are when given as a single drug or in combination, - the degree to which medical problems caused by BAY2965501 when given as a single drug or in combination, can be tolerated (also called tolerability), - what maximum amount can be given as a single drug or in combination, and - how it moves into, through and out of the body as a single drug or in combination. To answer this, researchers will look at: - the number and severity of medical problems participants have after taking BAY2965501 as a single drug or in combination for each dose level. These medical problems are also referred to as adverse events. - the (average) total level of BAY2965501 in the blood (also called AUC) after intake of single and multiple doses - the (average) highest level of BAY2965501 in the blood (also called Cmax) after intake of single and multiple doses Doctors keep track of all medical problems that participants have during the study, even if they do not think the medical problem might be related to the study treatment. In addition, the researchers want to know if and how the participants' tumors change after taking BAY2965501. The study will have two parts. The first part, called dose escalation, is done to find the most appropriate dose that can be given in the second part. For this, participants will be assigned to receive one of the planned doses and schedules of BAY2965501 as single drug or participants will be assigned to one of the increasing doses of BAY2965501 in combination with 200mg pembrolizumab. All participants will take BAY2965501 by mouth. Additionally, in the combination group, pembrozilumab will be given. In the second part, called dose expansion, all participants in the single drug group will receive up to 2 of the most appropriate doses of BAY2965501 from the 1st part as tablet by mouth. The participants in the combination group will receive the most appropriate dose of BAY2965501 from the first part. Participants in both parts of the study, will take the study treatment until the tumor gets worse (also known as 'disease progression'), or until the participants have medical problems. In general, the study treatment is planned for a maximum of 35 cycles. Each participant will be in the study for several months, including a screening phase of up to 28 days, few months of treatment depending on the participant's benefit, and a follow up phase after the end of treatment. The following approximate numbers of visits to the study site are planned: two during the screening phase, six in the first treatment month, one to three per month in the following periods. Participants in part two will be assigned to one of 3 groups depending on cancer characteristics. Study procedures described below may vary between these groups. During the study, the study team will: - take blood and urine samples - do physical examinations - check vital signs such as blood pressure, heart rate, body temperature - examine heart health using ECG (electrocardiogram) - check if the participants' cancer has grown and/or spread using CT (computed tomography) or MRI (magnetic resonance imaging) and, if needed, bone scan - take tumor samples (if required) The treatment period ends with a visit no later than 7 days after the last BAY2965501 dose in the single drug and combination group. About 30 and 90 days after the last dose and every 12 weeks thereafter, the study team will check the participants' health and any changes in cancer. This follow-up period ends with worsening of the cancer, start of new anti-cancer therapy, or until the participant leaves the study. In addition, the study doctors and their team will contact the participant every 12 weeks to learn about the participant's survival. This ends no later than 12 months after the last participant started treatment or by the end of the study, whichever comes first.
