Project description:Background: Systemic-Onset Juvenile Idiopathic Arthritis (SJIA) is a rare disease associated with dysregulated interleukin (IL)-1 activity. Objectives: To assess the efficacy and safety of Anakinra, an IL-1 receptor antagonist in SJIA and its effects on gene expression profiling. Methods: We conducted a multicenter, randomized, double-blind placebo-controlled trial. The primary objective was to compare the efficacy of a one-month treatment with anakinra (2 mg/kg subcutaneoulsy daily, maximum 100 mg) to a placebo between 2 groups of 12 SJIA patients each. Response was defined by a 30% improvement of the pediatric American College of Rheumatology criteria for JIA, resolution of systemic symptoms and a decrease of at least 50% of both C-reactive protein and erythrocyte sedimentation rate compared to baseline. An intention-to-treat analyze was performed. After Month 1 (M1), patients taking placebo were switched to Anakinra. Secondary objectives included tolerance and efficacy assessment for 12 months. Results: At M1, concluding the randomized trial, there was a significant difference in the response rate between patients treated with Anakinra (8/12 responders) and placebo (1/12) (p=0.003). The number of adverse events, mainly pain to injections, was similar between both groups. Ten patients from the placebo group switched to Anakinra at M1; nine were responders at M2. Between M1 and M12, six patients stopped treatment for an adverse event (Crohn’s disease, hepatitis), a lack of efficacy or a disease flare (2 cases each). Blood gene expression profiling at enrollment and upon follow-up allowed us to identify one set of dysregulated genes that reverted to normal values in the clinical responders and a second set, including interferon-inducible genes, that was induced by Anakinra. Conclusion: Anakinra is an effective treatment of SJIA. Its effect is associated with normalization of blood gene expression profiles in clinical responders and de novo induction of an interferon signature.

Project description:Autophagy selectively degrades aggregation-prone misfolded proteins caused by defective cellular proteostasis. However, the complexity of autophagy may prevent the full appreciation of how its modulation could be used as a therapeutic strategy in disease management. Here we define a molecular pathway through which recombinant interleukin-1 receptor antagonist (IL-1Ra, anakinra) affects cellular proteostasis independently from the IL-1 receptor (IL-1R1). Anakinra promoted H2O2-driven autophagy through a xenobiotic sensing pathway involving the aryl hydrocarbon receptor that, activated through the indoleamine 2,3-dioxygenase 1-kynurenine pathway, transcriptionally activates NADPH Oxidase 4 independent of the IL-1R1. By coupling the mitochondrial redox balance to autophagy, anakinra improved the dysregulated proteostasis network in murine and human cystic fibrosis. We anticipate that anakinra may represent a therapeutic option in addition to its IL-1R1 dependent anti-inflammatory properties by acting at the intersection of mitochondrial oxidative stress and autophagy with the capacity to restore conditions in which defective proteostasis leads to human disease.

Project description:Various studies showed a significant production/release of IL-1 beta following status epilepticus (SE) and during epileptogenesis. We studied the role of this cytokine in the epileptogenic process by blocking its production and downstream effects in vivo in a model of acquired epilepsy following SE induction. We used a pharmacological strategy consisting of the administration of two drugs, namely VX-765 and Anakinra, which selectively block the biosynthesis and the receptor type 1 of this cytokine, respectively.

Project description:A peptidomic analysis of plasma from patients with well characterised pancreatic neuroendocrine tumours (PNET) was performed. A nano LC-MS analysis identified a number of peptides from the glucagon gene, which were idenfiried in a previous case study using multiple immunoassays. Peptides to other proteins involved in peptide secretion were also identified. Plasma from a second glucagonoma patient was analysed using a high flow approach, and this identified similar peptides to the nano analysis. In order to demonstrate the potential clinical application of LC-MS to characterising neuroendocrine tumours, a large cohort of plasma samples were analysed to demonstrate the ability of this approach to identify glucagonoma patients, and differentiate from a single insulinoma patient

Project description:MTC-DOX is Doxorubicin or DOX, a chemotherapy drug, that is adsorbed, or made to "stick", to magnetic beads (MTCs). MTCs are tiny, microscopic particles of iron and carbon. When DOX is added to MTCs, DOX attaches to the carbon part of the MTCs. MTC-DOX is directed to and deposited in the area of a tumor, where it is thought that it then "leaks" through the blood vessel walls. Once in the surrounding tissues, it is thought that Doxorubicin becomes "free from" the magnetic beads and will then be able to act against the tumor cells. The iron component of the particle has magnetic properties, making it possible to direct MTC-DOX to specific tumor sites in the liver by placing a magnet on the body surface. It is hoped that MTC-DOX used with the magnet may target the chemotherapy drug directly to liver tumors and provide a treatment to patients with cancers that have spread to the liver.

Project description:Inflammatory factors that activate NFkB play an important role in the pathogenesis of chronic lymphocytic leukemia (CLL) but are not addressed specifically by current therapies. Interleukin-1 (IL-1) is a master-regulator of inflammation that is inhibited safely in humans by the IL-1 receptor antagonist anakinra. Anakinra was found to inhibit NFkB activity in CLL cells in an IL-1 receptor independent manner and had properties of an intracellular anti-oxidant in vitro. A phase I dose-escalation trial in 11 previously untreated CLL patients (NCT04691765) indicated anakinra was safe at doses up to 400 mg daily and produced transient clinical responses associated with down-regulation of NFkB and oxidative stress in circulating CLL cells in vivo. However, type 1 interferon (IFN)-signaling and c-MYC-regulated genes and proteins were induced at the same time.
