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.
Primary liver cancer is the sixth most common cancer worldwide, including hepatocellular carcinoma and intrahepatic cholangiocarcinoma, of which intrahepatic cholangiocarcinoma accounts for 10%-15%. Surgical resection is the only curative method for ICC, but most patients are diagnosed at an advanced stage, and only 15% of patients can undergo surgical resection. In locally advanced ICC patients without distant metastases, although the tumor was initially assessed as unresectable, these patients may have the opportunity for surgical resection after reducing the size tumor lesion and increasing the remnant liver volume through conversion therapy. The current standard first-line treatment for unresectable ICC is gemcitabine combined with cisplatin, with a median overall survival of only 11.7 months and an ORR of 26.1%. In view of the poor effect of the standard chemotherapy regimen, the NCCN guidelines recommend that patients could participate in clinical study. Hepatic arterial infusion chemotherapy can increase the local blood drug concentration and improve the tumor regression rate. By reducing the dose of systemic chemotherapy drugs concentration, the incidence of adverse reactions can be reduced. Hepatic arterial infusion chemotherapy may be a better choice for locally advanced intrahepatic cholangiocarcinoma. PD-1 immunotherapy combined with targeted therapy is expected to improve the prognosis of patients with intrahepatic cholangiocarcinoma. This study investigates the safety and efficacy of hepatic arterial infusion chemotherapy combined with sintilimab and bevacizumabin the treatment of unresectable ICC.
This study aims to explore the clinical characteristics and mechanism of inhibitors of janus kinase in the treatment of idiopathic inflammatory myopathies
This is a two-phase, open-label Phase Ib clinical trial to evaluate the safety and efficacy of TQB2618 injection combined with Penpulimab in patients with relapsed and refractory lymphoma
Chronic obstructive pulmonary disease (COPD) is a common, preventable, and treatable disease, that causes obstructed airflow from the lungs that causes persistent obstructive airflow limitation. Acute exacerbation, especially frequent exacerbation, is associated with an increased risk of death in COPD patients. The most common causes of acute attacks are viral and bacterial infections. This study will assess the efficacy and safety of sitafloxacin, a quinolone antibacterial drug, in participants with AECOPD.
Although systemic inflammatory response induced by cardiopulmonary bypass is believed as one of main reasons for these adverse events, the involved mechanism is still unclear.This cohort study would include patients undergoing on-pump valve surgery or CABG. By detecting the changes of immune cell expression profile and inflammatory related substances in blood, the spatiotemporal change curve of immune function of patients is drawn for avoiding or treating adverse events.
This observational matched prospective study aims to assess the effectiveness and adherence for inclisiran in combination with Lipid lowering therapies or Lipid lowering treatments (LLT) compared to other LLTs under conditions of routine clinical practice.
1. Research background NobelBiocare manufacture put forward a new abutment called on1. This concept is based on a two-stage abutment in which the on1 abutment is placed directly on the implant during surgery and will not be disconnected since then. At present, there are very a few clinical prospective studies about clinical effect of Nobelparallel CC implant combined with on1 abutment. 2. Research objective This study will evaluate the clinical efficacy of Nobel parallel with on1 abutment compared to traditional healing cap in posterior teeth in a short term(one year) and long trem (five year) follow-up. 3. Study design and methods: Design type: prospective clinical study. Study duration: 5 years Start time: From the date of adoption of ethics. End time: 2026. Follow up examination: Panoramic images will be taken at all times to measure the marginal bone level of the implant. Clinical examination and questionnaire survey will be conducted to obtain the implant conditions and patients' satisfaction. Periodontal indexes such as keratinized gingival width, plaque index, gingival index, bleeding on probe, probing depth of peri-implant tissue will be evaluate.
Percutaneous coronary intervention (PCI) remains the major revascularization strategy for patients with obstructive coronary artery disease (CAD).However,in a substantial number of PCI cases for acute coronary syndrome (ACS) and chronic coronary syndrome (CCS),periprocedural myocardial injury or myocardial infarction (MI) occurs,both these PCI-related complications may be associated with an increased risk of future major adverse cardiovascular events (such as death, re-infarction, and revascularization).The incidence of periprocedural myocardial injury varies according to the different definition and cardiac biomarker .For 4th UDMI criteria with hs-cTn, 78% to 85% patients who undergoing elective PCI may suffer from periprocedural myocardial injury. Experimental and clinical evidence highlight the abnormalities of the coronary microcirculation is one of the causes of myocardial ischemia.Coronary microvascular disturbances (CMD) have been associated with early stages of atherosclerosis even prior to any angiographic evidence of epicardial coronary stenosis, as well as to other cardiac pathologies such as myocardial hypertrophy and heart failure. In this study, we try to conduct a double blinded, randomized, placebo-controlled trial，the aim of our trial is: (1) to observe whether the prophylactically intracoronary administration of nicorandil and verapamil could reduce the occurrence of periprocedural myocardial injury and infarction in CAD patients undergoing elective PCI.;(2) to observe whether the prophylactically intracoronary administration of nicorandil and verapamil has protective effect on coronary microcirculation after elective PCI.
