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 protocol is to provide continued treatment access and safety follow-up for eligible participants who continue to derive a benefit from study intervention in the Pfizer sponsored lorlatinib parent studies that will be closed. Additional follow-up safety data collection will permit further characterization of the safety profile of lorlatinib in participants continuing to receive study intervention
The study is being conducted to determine the dose limited toxicity(DLT) and maximum tolerated dose(MTD) and recommended Phase 2 dose(RP2D) of HRS2398 in subjects with advanced malignant tumor ; The second objectives is to evaluate safety and preliminary efficacy and PK profile of HRS2398 in subjects with advanced malignant tumor ; Exploratory cohort is to explore the relationship between gene mutation and efficacy and resistance mechanisms.
Cognitive impairment is independently related to low birth weight, low birth length and small head circumference. SGA children who have not experienced height and / or head circumference catch-up have the worst cognitive function. The serum IGF-1 level of short SGA children is significantly lower than that of catch-up SGA children. This may be due to the defect of GH-IGF-1 axis, resulting in some hGH / IGF-1 deficiency. GH treatment can induce catch-up growth of head circumference, especially for those with small birth head circumference, growth hormone can help to improve IQ, behavior and self cognition of children with SGA. Two years after birth is the most critical period for children's physical, neurological, cognitive and emotional development. This study evaluated the effect of growth hormone treatment on the improvement of cognitive function and growth and development of symmetrical SGA children who did not show catch-up growth from 6 months to 2 years old. This is an innovative study. The minimum age of previous similar studies is 19 months. The starting age of this study is 6 months, and the results are to improve the cognitive development of SGA infants. This is the first of its kind. Although the safety of growth hormone in SGA infants younger than 2 years old has not been reported, it is based on a number of studies on the application of growth hormone in infants, such as PWS and GHD, It can be expected that there will be no short-term and long-term adverse reactions. The study was conducted in 17 hospitals led by Tongji Hospital Affiliated to Tongji Medical College of Huazhong University of science and technology
The purpose of the study is to evaluate the efficacy and safety of avatrombopag for the promotion of platelet engraftment after Allo-HSCT.
In this prospective, multicentered , diagnostic trial, nasal and fecal specimens will collected from patients with sepsis in two critical care units(ICU) at the enrollment day ,the third, seventh, and fourteen days after enrollment or until ICU discharge (whatever come first). Total DNA from the nasal and fecal specimens will be extracted, amplified, and sequenced to determined the characteristics of gut microbiota and nasal microbiota. Finally, the characteristics of gut microbiota and nasal microbiota combined clinical information will be used to construct a prediction model to predict the prognosis of sepsis.
CD276 (B7-H3) is a member of the B7 costimulatory molecule family. Its mRNA is widely expressed in tissues, but the protein expression is limited. It is expressed in resting fibroblasts, endothelial cells, osteoblasts, amniotic fluid stem cells and other non-immune cells, and The surface of induced antigen-presenting cells and NK cells. Many studies have revealed that B7-H3 is overexpressed in a variety of tumors, including melanoma, pancreatic cancer, breast cancer, prostate cancer, colorectal cancer and other tumors, and its expression level is closely related to the poor prognosis and clinical outcome of patients . Preclinical studies have confirmed that the expression of CD276 mRNA in pancreatic cancer tissues is significantly higher than that of normal adjacent groups.
Natural killer cells (NK cells) are derived from bone marrow lymphoid stem cells, which are a type of lymphocytes that can non-specifically kill tumor cells and virus-infected cells without pre-sensitization. NK cells can not only directly kill malignant diseased cells, but also participate in the regulation of immune cell response and play a role in a variety of tumor immunotherapy strategies. The 2-year survival rate of NK cells combined with stem cell therapy for patients with hematological malignancies reached 36%, which is significantly higher than the 2-year survival rate (about 15%) of stem cell therapy alone, which can extend the disease-free survival period of leukemia patients by an average of 1.5 years. Relapsed and refractory leukemia can achieve a complete remission rate of up to 40%.
Preclinical and clinical studies of CD19 CAR-T in r/r B-NHL have been extensively carried out. At the beginning of 2020, MorphoSys submitted its company-targeted CD19 monoclonal antibody to the FDA for r/r DLBL treatment and obtained FDA priority approval. It further confirms the safety and effectiveness of CD19 as a therapeutic target in r/r B-NHL. However, these CAR-T cells are constructed from patients' autologous T cells, and the production and preparation time is long; on the other hand, most patients have received multiple chemotherapy before CAR-T treatment, and the quantity and quality of T cells often cannot meet the needs of clinical treatment. It is also an important factor leading to the failure of CAR-T cell therapy, which limits the large-scale clinical application of CAR-T. T cells sourced from healthy people are not only sufficient in quantity and quality guaranteed, but also available at any time. In December 2020, lancet[2] reported a clinical study of 19 patients receiving allogeneic CAR-T cell therapy for B-ALL. 14 patients were evaluated as CR/CRi (67%) 28 days after treatment, with a median sustained remission Time 4.1 months. Allogeneic CAR-T cells are safe and effective for the treatment of B-cell malignant diseases, and their clinical application range is expected to further improve the remission rate and survival rate of patients with R/R B-cell non-Hodgkin's lymphoma.
Hospital-acquired infections (HAI) have been shown to increase length of hospital stay and mortality. Infections acquired during a hospital stay have been shown to be preventable. The skin of patients is considered a major reservoir for pathogens associated with hospital-acquired infections, and has been suggested as a potential target for interventions to reduce bacterial burden and subsequent risk of infection. The use of daily Chlorhexidine (CHG) bathing in intensive care patients has been advocated to reduce many of the infections in critically ill patients. However, the effectiveness of CHG bathing to reduce ICU infections has varied considerably among published trials, making the effectiveness of CHG bathing in ICU patients uncertain.
