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 main purpose of this study is to determine the tolerability and side effects related to lebrikizumab comparing with placebo given as a single dose administered under the skin to healthy Chinese participants. The study will also assess how fast lebrikizumab gets into the blood stream and how long the body takes to get rid of it. Each enrolled participant will receive a single dose of either Lebrikizumab or placebo. For each participant, the total duration of the study will be approximately up to 21 weeks, including screening period.
This is a prospective, single-arm, single-center registry study to investigate 6-month progression-free survival with Dalpiciclib, a CDK4/6 kinase inhibitor, plus letrozole in patients with unresectable refractory or resistant recurrent HR-positive, HER2-negative gynecologic solid tumors." Dalpiciclib is a CDK4/6 kinase inhibitor that selectively inhibits the activity of CDK4/6 kinase, so that the complex with Cyclin D cannot phosphorylate the downstream Rb protein and prevent cells from entering the S phase from G1 phase, thereby inhibiting cell proliferation and anti-tumor effects.
Early exploratory clinical study of the safety, tolerability and initial efficacy of JY231 injection in the treatment of refractory autoimmune diseases
Lung cancer is with the highest incidence rate and mortality among people over 60 years old in China. Postoperative pulmonary complications (PPCs) is the most common complication after pneumonectomy, which has a significant impact on the short-term and long-term prognosis of patients, and is even the primary risk factor leading to early postoperative death. High fraction of inspired oxygen (FiO2) is an independent risk factor for PPCs, but it is difficult to achieve oxygenation while avoiding hyperxemia during one lung ventilation (OLV). We will randomly divide patients who plan to undergo thoracoscopic pulmonary resection into two groups. During OLV, titration will be used to determine the optimal FiO2 for titration group while FiO2 of 80% will be used for mechanical ventilation for control group. The incidence of postoperative PPCs, hypoxia/hyperxemia, oxygenation index (PaO2/FiO2) and intrapulmonary shunt rate (Qs/Qt), oxidative stress indicators, and prolonged hospital stay will be observed in both groups of patients. We will evaluate the effectiveness and safety of titrating inhaled oxygen concentration in lung protection during OLV.
The goal of this clinical trial is to learn about efficacy and safety of dual antiplatelet therapy in ischemic stroke with intracranial artery stenosis. The main question it aims to answer are: whether aspirin combined with clopidogrel for 3 month is better than 1 months for patients with non-cardiogenic cerebral infarction with intracranial artery stenosis. Participants will get dual antiplatelet therapy (aspirin plus clopidogrel) for 1 month or 3 months within 7 days of the first stroke. Researchers will compare experimental group (3 months dual antiplatelet therapy) with comparison group (1 month dual antiplatelet therapy), to see if experimental group would reduce stroke recurrence or mortality, and increase bleeding and other adverse prognosis.
This study aims to evaluate the safety and efficacy of hippocampal-sparing WBRT combined with SRS as first-line treatment for SCLC patients with brain metastases.
This study will evaluate the effect and safety of 608 in patients with AS.
Colon cancer is one of the most common malignant tumors with an increasing incidence rate in China. Surgical resection is still the main treatment for colon cancer at present. Radical surgery followed by three/six months chemotherapy is the standard of care for stage III colon cancer; however, patients with different risk factors have different prognosis. The IDEA trial divided stage III colon cancer patients into low-risk (T1-3/N1) and high-risk (T4 or N2) groups, and showed that for some low-risk patients, three months chemotherapy did not decrease survival outcomes, while for some high-risk patients, the recurrence risk was still high even after six months chemotherapy. Therefore, it's worth to explore other risk stratification factors beyond T and N stage for these patients. Circulating tumor DNA (ctDNA) is derived from cancer cells and can be detected in blood. Literatures have reported that ctDNA can be used for tumor diagnosis, therapeutic monitoring, and prognosis assessment in multiple cancers, including colon cancer. The GERCOR-PRODIGE trial, an accompanying study of IDEA, reported that in the high-risk group of stage III colon cancer, patients with ctDNA-positive and receiving six months chemotherapy had similar prognosis to these with ctDNA-negative and receiving three months chemotherapy; in the low-risk group, patients with ctDNA-negative and receiving three or six months chemotherapy had similar prognosis to patients with ctDNA-positive and receiving 6 months chemotherapy, but patients with ctDNA-positive and receiving three months chemotherapy had the worst prognosis. The results of this trial suggests that ctDNA can be potentially used as a further stratification factor to guide adjuvant chemotherapy for stage III colon cancer. Several RCTs have shown that double-drug regimens chemotherapy based on oxaliplatin (FOLFOX and XELOX) can improve the prognosis of patients with stage III colon cancer. Therefore, the ESMO, NCCN, and CSCO guidelines recommend FOLFOX or XELOX for stage III colon cancer. The 2-year disease-free survival rate of these patients who received FOLFOX or XELOX chemotherapy was about 80%. It is worth to further explore how to improve the prognosis of these patients. Recently, the triple-drug regimens of oxaliplatin, irinotecan, and fluoropyrimidine (FOLFOXIRI) has been found to be superior to FOLFOX or XELOX for metastatic colorectal cancer in terms of response rate and survival. Currently, research on FOLFOXIRI plus targeted therapy in metastatic colorectal cancer is progressing rapidly, but there is little research on the use of FOLFOXIRI as adjuvant chemotherapy for stage III colon cancer. There is an ongoing international multicenter phase III RCT comparing FOLFOXIRI and FOLFOX6 adjuvant chemotherapy for high-risk stage III colon cancer patients, but it did not further stratify patients based on postoperative ctDNA status, which may result in some patients receiving excessive chemotherapy. The present study plans to enroll patients with stage III colon cancer with positive ctDNA within 1 month after surgery. These patients will receive 2 cycles of XELOX chemotherapy followed by retesting ctDNA. During the waiting period of the ctDNA results (approximately 3 weeks due to the testing time), all patients will receive another cycle of XELOX chemotherapy. If the ctDNA remains positive, the patients will be randomly assigned to receive 8 cycles of FOLFOXIRI as intensified adjuvant chemotherapy or 5 cycles of XELOX regimen as standard adjuvant chemotherapy. If the ctDNA is negative, the patients will continue to receive 5 cycles of XELOX chemotherapy. Within 3 weeks after the completion or termination of chemotherapy, ctDNA will be retested again. The aims of this study are to explore the value of ctDNA in surveillance of chemosensitivity and to preliminarily evaluate whether the intensified chemotherapy with FOLFOXIRI can increase ctDNA clearance as well as its safety in stage III colon cancer.
Stem cells are non-terminal cells that can self renew and replicate through symmetric or asymmetric division, with the potential to differentiate into different types of cells and tissues. Multiple studies have shown that mesenchymal stem cell has good safety and effectiveness in improving acute or chronic liver injury. Randomized controlled trials have confirmed the efficacy of single infusion of stem cells in treating ESLD. It seems that the multiple infusion is better than single infusion.
The goal of this multicenter, single-arm, observational cohort study is to investigate the efficacy and safety of irinotecan in combination with trifluridine-tipiracil and bevacizumab in colorectal cancer with prior oxaliplatin and fluoropyrimidine-based chemotherapy (including 5-FU/capecitabine/S-1) exposure in the metastatic setting or within 12 months of recurrence.
