Filter by:In a randomized, doubleblind and placebo-controlled trial we assess both clinical and cellular effects of atorvastatin in patients with liver cirrhosis. 162 participants will be allocated to atorvastatin 10-20 mg or placebo for 18 months. Clinical outcomes of survival, hospitalizations and safety will be evaluated. Also, the trial will investigate cellular functions in the liver by mass spectrometry proteomics, and single cell transcriptomics as well as exploring atorvastatin effects on different fenotypes by metagenomics.
it is a prospective longitudinal observational study, aiming to to identify clinical, and biochemical baseline predictors of motor and non-motor PD progression in sample of Egyptian patients. it measures the baseline motor, non-motor, biochemical and imaging characteristics at enrollment and its relation to PD progression over 3 years
Invasively measured fractional flow reserve (FFR) has proven to be useful in guiding coronary revascularization. Several studies have shown that it is justified to treat lesions with a value of 0.80 or lower and safe to defer from PCI in lesions with a value of >0.80. Recently, computational fluid dynamics have allowed FFR measurement from coronary computed tomography angiography images (FFRCT) with excellent diagnostic accuracy compared to invasive FFR. FFRCT can also effectively guide revascularization safely deferring patient with FFRCT >0.80 from invasive angiography. In functionally non-significant lesions, computational fluid dynamic models in addition to CT plaque characteristics (low attenuation, positive remodelling, spotty calcification and napkin-ring sign) may be able to predict which lesions will become flow-limiting, causing clinical events in the future. This study will evaluate disease progression in intermediate lesions (invasive FFR 0.81-0.90 at baseline) using FFRCT at 2 years and determine whether CT characteristics may help to identify lesions that are more susceptible for FFR decline. Additionally, we will correlate CT characteristics with coronary events (a composite endpoint consisting of all-cause mortality, target-vessel myocardial infarction and clinically driven target-vessel revascularization) up to 5 years after the baseline invasive FFR.
There is limited empirical data documenting disease progression and impact on quality of life for patients with X-linked hypophosphatemia (XLH). This study seeks to investigate the impact of XLH in adults living in the UK retrospectively and prospectively over a 12 month period, using qualitative interviews, SEIQoL-DW, EQ-5D-5L, SF36 quality of life tools. XLH is a rare, genetic, chronically debilitating and deforming condition (www.nice.org.uk/guidance/HST8). XLH is characterised by renal phosphate wasting, hypophosphatemia and defective bone mineralisation. The incidence of XLH is reported to be between 1:20,000 and 1:25,000 live births. In the UK, it is estimated that there are around 250 paediatric XLH patients and around 2,500 adult XLH patients (Delmestri,et al [Unpublished report]2018). The clinical phenotype of XLH is varied amongst patients, even among affected members of the same family. This can range from no signs or symptoms, slow growth in children, short stature, bone abnormalities that can affect movement and result in pain, bowed legs and knocked knees (where lower legs are positioned at an outward angle), tooth abscesses and excessive dental caries and hearing loss (adult patients only). This study will recruit 36 adults living with XLH, who are aged 28 years or over and living in the UK. The study will be advertised by the Sponsor and funder Medialis Ltd and via the patient organisation Metabolic Support UK. All study activities will take place via tele-visits and online questionnaires. The study will last approximately 2 years, allowing for one-year recruitment and a further 12 months to conduct all study visits.
Results of previous study showed high objective response but short-term activity of anti-angiogenesis tyrosine kinase inhibitors in advanced osteosarcoma. Given the recent success of immunotherapies, combinations of antiangiogenics with immune checkpoint blockers have become an attractive strategy. The investigators had completed an prospective phase 2 trial of the combination of apatinib and camrelizumab on advanced osteosarcoma and showed prolonged progression-free survival for this combination. Famitinib is a novel tyrosine kinase inhibitor targeting VEGFR-2, -3 and FGFR-1, -2, -3, -4 with high affinity, which showed broad antitumor activity against a variety of xenograft models. A Study to Compare the Efficacy and Safety of Levatinib with or without Ifosfamide and Etoposide in Children, Adolescents and Young Adults With Relapsed and Refractory Osteosarcoma showed promising median PFS of 11.3 months. Thus we also try to investigate the combination efficacy of TKIs with chemotherapy in advanced osteosarcoma. This study aims to investigate the recommended phase 2 dose for pediatric use of famitinib in combination with camrelizumab and trys to explore the efficacy and safety for single drug famitinib, famitinib and camrelizumab and famitinib and ifosfamide in patients with inoperable high-grade osteosarcoma progressing after chemotherapy.
The purpose of this phase II, single-arm, open-label, three center study is to evaluate the efficacy, safety, and tolerability of sEphB4-HSA in patients with mCRPC (metastatic castration-resistant prostate cancer). The study drug, sEphB4-HAS, is a form of protein that has not been approved for sale by the United States Food and Drug Administration (FDA). The study drug prevents tumor cells from multiplying and blocks several compounds that promote the growth of blood vessels that bring nutrients to the tumor.
This phase I/II trial studies the side effects and best dose of modified immune cells called CD19-CD22 chimeric antigen receptor (CAR) T cells in treating patients with CD19 positive(+), CD22+ B-acute lymphoblastic leukemia, chronic lymphocytic leukemia, or non-Hodgkin's lymphoma that has come back (recurrent) or does not respond to treatment (refractory). T-cells are collected from the patient and genetic materials called "chimeric antigen receptors (CAR)" are transferred to the collected T-cells. The CAR T-cells are then infused back to the patient's body. Giving CD19- CD22 CAR T cells after chemotherapy may help to control the disease.
This randomized double-blind placebo-controlled trial tests whether intervention with atorvastatin delays development of castration resistance compared to placebo during androgen deprivation therapy (ADT) for prostate cancer.
The presence of circulating tumor cells (CTCs) in the blood of prostate cancer patients has been shown to be an important indicator of metastatic disease and poor prognosis. Additionally, changes in CTC number throughout treatment have been demonstrated to reflect therapy response. However, the CellSearch® (Menarini-Silicon Biosystems) is the only FDA- and Health Canada-cleared CTC platform available at the present time, and is thus considered the current "gold standard" for clinical CTC analysis. Notably, CTCs are undetectable in ~35% of metastatic CRPC patients. This suggests that either CTCs are truly not present in >1/3 of patients with advanced metastatic disease; and/or that CTCs are present but not detectable as they do not meet the standard CellSearch® definition of CTCs. Given the accumulating evidence that prostate cancer cells can lose epithelial characteristics as they evolve towards a more metastatic phenotype, the investigators believe the latter scenario is most likely. The epithelial-to-mesenchymal transition (EMT) is a critical process during embryonic development and cancer metastasis. Although the role of androgen receptor (AR) signaling in EMT is poorly understood, studies have also demonstrated that EMT may be facilitated by androgen deprivation, castration-resistance, and/or disruption of androgen signaling. Importantly, several clinical studies have demonstrated that CTCs with a purely mesenchymal phenotype are undetectable by CellSearch®, but that the presence of mesenchymal marker expression on CTCs with a hybrid epithelial-mesenchymal phenotype is indicative of poor prognosis. In addition, previous pre-clinical data from the Allan laboratory has demonstrated that in animal models, prostate cancers with a mesenchymal phenotype shed greater numbers of CTCs more quickly and with greater metastatic capacity than those with an epithelial phenotype. Notably, the clinically-used CellSearch®-based assay captured the majority of CTCs shed during early-stage disease in vivo, and only after the establishment of metastases were a significant number of undetectable CTCs present. This suggests that current clinical assays may be limiting ability to capitalize on the full potential of CTCs, and that a greater understanding of CTC biology is necessary in order to guide future technology development and translation to the clinic.
This phase I/II trial studies the best dose and side effects of encorafenib, cetuximab, and nivolumab and how well they work together in treating patients with microsatellite stable, BRAFV600E gene mutated colorectal cancer that cannot be removed by surgery (unresectable) or has spread to other places in the body (metastatic). Encorafenib and cetuximab may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.Giving encorafenib, cetuximab, and nivolumab may work better in treating patients with colorectal cancer compared to cetuximab alone.
