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 purpose of this study is to investigate the long-term outcomes of conservative management in patients with moyamoya disease and their first-degree relatives, and provide potential pathogenesis of moyamoya disease.
The primary purpose of this study is to evaluate the feasibility, the safety and the efficacy of the transapical beating-heart septal myectomy for the treatment of hypertrophic obstructive cardiomyopathy. This is a prospective, single-arm, single-center, first-in-man study.
This study is designed to evaluate the effectiveness and safety of low-dose rituximab in patients with refractory myasthenia gravis. The traditional treatment of MG is immunosuppressive therapy, usually beginning with corticosteroids. However, up to 70% of treated patients show an incomplete response, including 10 - 30% who are unresponsive. Corticosteroids and other immunosuppressive therapies presented also many side effects. The investigators propose to evaluate in a pilot, open, prospective, single central study, the interest of rituximab (RTX) in the treatment of patients with refractory MG. Fifty patients with refractory MG will be included in the study and divided into two stages: 14 patients in the first stage were followed up after using RTX according to the study protocol. The study will move into the second stage on if the number of effective cases is greater than 3, otherwise, the study will be discontinued (based on Simon's Optimal Two-stage Design). The remaining 36 patients were enrolled in the second stage. In the first and second stages, the treatment plan and follow-up plan were consistent. The therapeutical schema is rituximab 100-200 mg/week for a total of 2-4 times, followed by adequate organ function, laboratory parameters and assessment of MG after each injection and end of follow up for 24 weeks.
The purpose of this study is to evaluate the safety and efficacy of transarterial chemoembolization (TACE) in combination with PD-1/PD-L1 Inhibitors and molecular target therapies in patients with Intermediate-stage hepatocellular carcinoma (HCC).
The primary study objective is to evaluate medium- and long-term safety of HBM9161 in combination with background treatment for gMG patients through the observation on adverse events and laboratory abnormalities during study period.
This is a multicenter, single-arm phase II clinical trial to evaluate the efficacy and safety of RC48 in metastatic human epidermal growth factor receptor 2 (HER2) expressing breast cancer with abnormal activation of PAM pathway.
This is a Multi-center, Open-label, Single-arm Phase II Study to Evaluate the Efficacy and Safety of HL-085 in the treatment of Adult Participants with Neurofibromatosis Type 1 (NF1) and Inoperable Plexiform Neurofibromas(PN)
Identifying patients at risk of NAFLD(Nonalcoholic fatty liver disease), especially severe disease with NASH(nonalcoholic steatohepatitis) and fibrosis, is critical. Prevalence of NAFLD in PLWH(People Living With HIV) evaluated by different imaging techniques including US (ultrasonography), elastography, CT(computed tomography ), and magnetic resonance varies from 13% to 58.6% in all published studies. In previous studies, the effect of ART(Anti-Retroviral Therapy) on NAFLD was limited. A cross-sectional analysis found that INSTI（Integrase strand transfer inhibitor） was associated with a higher prevalence of steatosis in AIDS (acquired immunodeficiency syndrome) patients. However, it is not clear whether there is a difference in the degree of nonalcoholic steatosis between AIDS patients receiving NNRTI(non-nucleoside reverse transcriptase inhibitors). Therefore, the investigators plan to conduct a prospective study to assess whether there is any difference in the degree of nonalcoholic steatosis and fibrosis between Chinese HIV(human immunodeficiency virus)/AIDS patients after initial treatment with NNRTI or INSTI, or switching from NNRTI to INSTI.
Lumbar disc herniation compressed the nerve cause pain, numbness, weak legs called sciatica, which seriously decrease the quality of life and work efficiency. Both collagenase chemonucleolysis(CCNL) and percutaneous endoscopic lumbar discectomy (PELD) was effective to treat lumbar disc herniation(LDH) requires surgery. whether functional clinical outcomes of CCNL vs PELD effect on LDH was superior, and no study provided convincing evidence.
