There are about 35759 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.
Subjects were inoperable Chinese patients with histologically or cytologically confirmed advanced malignant solid tumors (mainly focusing on MSS type colorectal cancer) who had failed standard systemic therapy. In the first stage, each subject was given three doses on day 1, day 3 and day 5, and was divided into 4 dose groups, including 1 subject in the first dose group and 3-6 subjects in each of the last three dose groups. The second stage was the dose extension stage, with 2 dose groups, at least 10 subjects were enrolled in the selected group, and the administration method was the same as that of the first stage. There were about 20-60 cases in the two stages.
Assess the effects of a single IV bolus of HSK3486 single dose on cardiac repolarization for healthy subjects.
Large doses of systemic corticosteroids ，severe lung tissue damage and longer COPD diagnosis may increase the risk of IPA in patients with chronic structural lung disease. By comparing the risk factors of aspergillus colonization group and aspergillus infection group, the main risk factors of aspergillus pneumonia were determined.
Objectives of Study： Through the cross-sectional study of stroke and depression, key biomarkers are targeted by screening disease-associated intestinal bacteria, metabolites and immune factors through multi-omics techniques.
Multiple myeloma (MM) is a malignant disease characterized by the abnormal proliferation of clonal plasma cells. However, multiple myeloma remains an incurable disease and requires the exploration of more effective treatment methods to improve the efficacy of relapsed refractory multiple myeloma and prolong survival time.Currently, clinical application of CAR-T is mostly based on autologous T cell preparation, while relapsed/refractory AML patients have undergone multiple chemotherapy treatments, resulting in impaired self-T cell function, which affects the efficacy and prognosis of CAR-T therapy. Therefore, it is necessary to find new alternative treatments. NK cells are important immune cells in the body and are an important component of innate immunity. Compared with CAR-T cell therapy, CAR-NK cells have unique advantages in adoptive cell therapy. NKG2D receptor is an activating receptor expressed on NK cells, which can recognize NKG2D ligands (NKG2DL) expressed on tumor cells, activating NK cell killing activity through NKG2D-NKG2DL interaction. Therefore, the investigators plan to treat relapsed multiple myeloma by infusing NKG2D-CAR-NK cells to evaluate its efficacy and safety.
The goal of this observational study is to explore the association of peptidoglycan fragments derived from gut microbiota with colorectal cancer (CRC). The main question it aims to answer is: Are peptidoglycan fragments from the gut microbiota associated with the progression of colorectal cancer? Participants will provide biological specimens (blood, feces, colon tissue obtained during surgery)
This study is a single-center, prospective, single-arm exploratory study aimed at evaluating the efficacy and safety of trifluridine/tipiracil in combination with cetuximab in the treatment of third-line and above RAS/BRAF wild-type metastatic colorectal cancer.
This registry aims to evaluate the long-term prognosis and valve durability of transcatheter aortic valve replacement (TAVR) in a real-world setting. Baseline characteristics, procedural data, and clinical outcomes will be collected in a prospective and observational manner.
Tourette syndrome is a refractory type of tic disorder. Previous clinical studies have confirmed that Tuina has a good effect on TS, but the mechanism of action is still uncertain. Studies have found that the pathogenesis of TS may be related to immune factors, and patients will accompanied by the overflow of inflammatory factors such as interleukin-1β (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) during the onset of the disease. Other studies have found that the serum levels of IgG1, IgG2, IgG3, IgG4, IgGM, IgGA, IgGE, complement C3 and complement C4 are closely related to the pathogenesis of TS, and the abnormal humoral immune response mediated by food intolerance has an important impact on the pathogenesis of mental illness in children. The immune system plays a very complex role in TS. Based on this, we hypothesized that there may be differences in serum humoral immune effector levels between children with TS and healthy children, whether these differences are related to the consumption of certain allergenic foods or not, and so does Tuina spinal balancing can improve the clinical symptoms of children with TS by changing the levels of inflammatory and immune factors in peripheral serum. This study studied the peripheral mechanism of humoral immune effector mediated by Tourette syndrome and the intervention effect of Tuina through comprehensive scale analysis and advanced laboratory technology, which will provide a scientific theoretical basis and a safe and effective method for the treatment of multiple tics, and will have broad application prospects.
HMA maintenance therapy is expected to benefit OS and RFS in AML patients with favorable risk.
