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.
According to statistics, in 2020, new head and neck malignancies in the world accounted for 4.9% (931931 cases) of malignant tumors in the whole body, and the new death cases were 467125, accounting for 4.7% of malignant tumors in the whole body. The high incidence rate and mortality brought great burden to the medical system. In addition, due to various types of head and neck cancer, hidden location, impact on function and quality of life, and low overall survival rate, this type of disease has seriously threatened human health and social development. The incidence of oropharyngeal cancer and laryngeal cancer is more subtle. Traditional examination methods include CT(computer tomography), MR(magnetic resonance), and laryngoscopy, but they cannot make accurate judgments on the systemic TNM(primary tumor, regional nodes, metastasis) staging of oropharyngeal cancer and laryngeal cancer. 18F-FDG(18F-2-fluoro-2-deoxy-D-glucose fluorodeoxyglucose) PET/CT examination can better diagnose and stage compared to traditional examination methods. However, due to the interference of more inflammatory lesions or physiological uptake in the pharynx, the false positive rate of 18F-FDG PET/CT examination is significantly increased, 18F-FAPI(18F-fibroblast activation protein inhibitors) is a novel broad-spectrum tumor imaging agent that can be specifically uptake by fibroblasts in the tumor microenvironment, and has lower physiological uptake and acute inflammatory lesion uptake in the larynx. 18F-FAPI PET/CT examination can more accurately stage tumors throughout the body than 18F-FDG PET/CT examination. Combined with PET/MR local scanning, it will further improve the accuracy of T and N staging of local tumors. Therefore, It is of great significance for clinical diagnosis and treatment to effectively and reliably determine the systemic TNM staging of oropharyngeal and laryngeal cancer through non-invasive methods.
Upper-extremity impairment after stroke remains a major therapeutic challenge and a target of neuromodulation treatment efforts.In this open-label, randomized phase I trial, we applied deep brain stimulation to the cerebellar dentate nucleus combined with bilateral or unilateral stimulation. We hypothesized that bilateral stimulation was superior to unilateral stimulation as the motor rehabilitation after stroke benefits from both side of cerebellum.
The short-term and long-term efficacy of recanalization therapy needs to be further confirmed by large-sample prospective studies. The comparison of success rate, complication rate and efficacy among the three recanalization modalities also needs to be further explored. The purpose of this cohort study is to observe the success rate, efficacy and safety of recanalization treatment for non-acute occlusion, and to further compare the advantages and disadvantages of CEA, endovascular intervention and hybrid surgery.
The primary objective of this trial is to evaluate the safety and efficacy of SINOMED IAS in patients with intracranial aneurysms.
This study is an open-label, single-center trial which aim to evaluate of efficacy and safety of human umbilical cord-derived mesenchymal stem cells (hUC-MSCs) combined with platelet-rich plasma (PRP) in stage 3 and 4 stress injury.
Malignant tumor of bone is rare with poor prognosis. Surgery is the main treatment for non- metastatic bone tumor. Although neoadjuvant chemotherapy for non-metastatic bone tumor cannot improve survival rate based on adjuvant chemotherapy, it can reduce and clarify tumor boundary. Control of local recurrence rate is the core objective of oncotherapy. Surgery way and boundary have a significant effect on prognosis of non- metastatic bone tumor. Narlumosbartmab, a RANKL inhibitor, can make tumor boundary clear and reduce surgical difficulty by inhibiting osteoclast. This is a prospective, randomized, controlled, two-arm, open, single-center clinical trial to compare the efficacy and safety of narlumosbartmab combined with neoadjuvant chemotherapy and neoadjuvant chemotherapy alone in bone-derived malignancies with bone lytic lesions and multinucleated giant cells. Investigators mainly observe the local recurrence rate to evaluate the survival benefit for patients with poor prognosis.
A total of 17 to 23 participants are anticipated to be enrolled in the Phase I clinical trial, which is further divided into two distinct parts: one part involves single-agent cell therapy, while the other entails a combination of cell therapy and Serplulimab Injection. To be more precise, the study aims to include patients who have been diagnosed with metastatic or locally advanced refractory/recurrent malignant solid tumors and have shown resistance to standard therapeutic interventions. These tumor types may encompass head and neck cancer, ovarian cancer, lung cancer, melanoma, and others.
This is a multicenter, open study to evaluate the long-term safety and efficacy of TPN171H in men with erectile dysfunction.
This is a single-arm, prospective, exploratory clinical study to evaluate the efficacy and safety of endostar combined with stereotactic body radiation therapy (SBRT) and Envafolimab in patients with advanced gastrointestinal cancer after multi-line treatment.
To compare the incidence of the composite endpoints of non-fatal ischaemic stroke, transient ischaemia (TIA) and all-cause mortality at 12-month follow-up after implantation of Bridge for the treatment of symptomatic vertebral artery stenosis in subjects who had been taking different durations of dual-antiplatelet therapy (3 vs 6 months) and ticagrelor monotherapy.
