Filter by:A 4-month, randomized, prospective, open-label comparison trial of hydroxychloroquine vs. pioglitazone in type 2 diabetic patients inadequately controlled on maximally tolerated doses of metformin plus a sulfonylurea.
A comparison of anterioposterior versus oblique view approach method for fluoroscopically-guided epidural block in the midthoracic region. The investigators evaluate differences on total radiation time and technical feasibility between anterioposterior and oblique view approach method.
Study Title: Intercalating and maintenance Gefitinib in combination with chemotherapy (gemcitabine plus carboplatin) as first-line treatment for patients with advanced EGFR mutation-positive non-small cell lung cancer: A randomized, open-label, multiple-centre study. Target population-Treatment naive EGFR mutant-positive advanced NSCLC patients. Study Objectives - Primary Study Objective: To investigate whether intercalating and maintenance Gefitinib in combination with chemotherapy improve the Progression-Free Survival (PFS) vs. Gefitinib alone in advanced NSCLC with EGFR activating mutation. - Secondary Study Objective： To evaluate whether intercalating and maintenance Gefitinib in combination with chemotherapy improve the Objective Response Rate (ORR), Disease control rate (DCR), Overall survival (OS), 2-year OS rate, QOL vs. Gefitinib alone. Evaluation the safety of Intercalating and Maintenance Gefitinib in combination with chemotherapy. - Exploratory objective: PFS of arm A vs. PFS 1 + PFS 2 of arm B Dynamic biomarker analysis using blood sample a: The PFS 1 of arm B is the time from randomization to disease progression of 1st-line therapy or death from any cause, whichever occurs first. The PFS 2 of arm B is the time from the time of PFS 1 to disease progression of 2nd-line therapy or death from any cause, whichever occurs first. Study Design-Prospective, open-label, randomized, multi-center study.
This study will evaluate the safety and tolerability of epacadostat (INCB024360) administered in combination with atezolizumab (MPDL3280A) in patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) that have been previously treated with platinum-based chemotherapy and Stage IV urothelial carcinoma who have failed a platinum-based chemotherapy regimen. The study will be conducted in two phases. The dose escalation phase will utilize a 3 + 3 design to identify the maximum tolerated dose (MTD) or a Pharmacologically Active Dose (PAD) of the combination. This will be followed by a dose expansion phase, which will be comprised of three cohorts. Expansion Cohorts 1 & 2 will further evaluate the safety, tolerability, efficacy, pharmacokinetics (PK), and pharmacodynamics at the dose identified in phase one. Expansion Cohort 3 will evaluate the change in biomarker expression following treatment with epacadostat as monotherapy followed by epacadostat and atezolizumab administered in combination.
Ketorolac is a non-steroidal anti-inflammatory drug (NSAID) that is typically given to both adults and children by the intravenous (IV) or intramuscular (IM) route for analgesic purposes. Ketorolac can also be given by the intranasal (IN) route using a mucosal atomization device (MAD). We aim to study the pharmacokinetics of ketorolac when administered by the IN route using the MAD.
Respiratory viruses are known to be risk factors for asthma (e.g respiratory syncytial viruses, RSVs, and Human Rhinoviruses, HRVs, may induce bronchiolitis, and wheezing illnesses respectively). The common flu is also known to be a risk factor and the Centers for Disease Control and Prevention (CDC) recommends that asthmatics receive the annual flu vaccine, as a high-risk group for related asthma exacerbations. The investigators will be evaluating the variation in individual responses over time after controlled immune activation following influenza vaccination of monozygotic twins, both discordant for asthma, and concordant non-asthmatic. The transition from initial healthy to immune-system activated physiological states post vaccination will provide unprecedented molecular (omics) data on the molecular dynamics of immune response to vaccination, and novel insight into the flu response. The investigators will infer novel networks and pathways and as well as the dynamics of genes and mechanisms involved in asthma, flu vaccination, and individual responses, and correlate them to evaluated personalized genetic risks in the same study. The investigators will be able to also contrast the vaccination response in asthmatic and non-asthmatic individuals, in a longitudinal approach which has never been performed before using multiple-omics that included an immunization response.
In this research study, the investigators will determine whether a procedure called Extracorporeal Photopheresis (ECP) is helpful in preventing progression of disability in people with SPMS when compared to monthly corticosteroid infusions. This study will determine whether ECP has an effect on inflammatory cells in people with SPMS and whether it has a beneficial therapeutic effect.
Objective of study: To evaluate the safety and efficacy of infusional gemcitabine prior to HDM (high-dose melphalan) as HDCT (High Dose Chemotherapy) followed by autologous stem cell transplantation in patients with relapsed/refractory lymphoma.
The clinical efficacy of double filtration plasmapheresis(DFPP) in patients with antineutrophil cytoplasmic autoantibody associated glomerulonephritis(AAGN).
The inflammatory tumor micro-environment is a consequence and a driver of tumorogenesis. On one hand it promotes antitumor immune responses and on the other hand it favors development and progression of cancerous lesions. Factors regulating the complex interplay between epithelial and immune cells are still poorly characterized. Extracellular ATP (eATP) acting on the purinergic P2X7 receptors (P2RX7) has recently emerged as a key signaling pathway in the immune response. Recent data have revealed the crucial role of P2RX7-NLRP3-Caspase-1 for priming dendritic cells (DC) within the tumor microenvironment upon treatment with certain types of chemotherapy drugs. Despite this important discovery, no previous study has so far investigated the global in vivo effect of P2RX7 modulation in inflammation-induced carcinogenesis of mucosal tissues. Our consortium, endowed by a long standing experience in the field of mucosal immunology, inflammation and signaling, already demonstrated that the P2RX7 is differentially expressed in the mucosa of patients with active and quiescent inflammatory bowel disease (IBD), where eATP is present at very high concentration, and that P2RX7 controls an amplification loop of the inflammatory response (Cesaro et al., 2010). Furthermore, we uncovered that P2RX7 controls homeostasis, survival and function of regulatory T cells (Hubert et al., 2010). In addition, our recent demonstration that P2RX7 deficiency lowered mucosal inflammation but unexpectedly enhanced tumor formation in vivo warrants additional efforts to explore the molecular and cellular mechanisms accounting for this effect and suggest that enhancing P2RX7 function may have an anti-tumor therapeutic effect. These observations emphasize the tumor suppressor role of P2X7 receptor, warrant further investigation to better understand the molecular mechanisms responsible for this anti-tumor effect and suggest that enhancing the function of P2X7R could have a therapeutic effect significant antitumor. Our main objectives is to explore the role of P2RX7 in healthy, inflammatory and cancerous colonic mucosa. For this we will map the expression of the protein P2RX7 and realize genotype of P2RX7 forms in inflammatory diseases and cancer of the colon.
