CRx-119 is a novel synergistic combination drug candidate discovered using the CombinatoRx combination High Throughput Screening (cHTS(TM)) technology with potential therapeutic use in a broad range of immuno-inflammatory conditions. CRx-119 is a combination of a low dose of the steroid prednisolone, 3mg, and amoxapine.
Dược Lực Học : CRx-119 is a novel orally available syncretic drug candidate in clinical development for immunoinflammatory diseases. A syncretic drug comprises two compounds that are designed to act together synergistically through multiple pathways to provide a novel therapeutic effect which neither component alone can achieve. CRx-119 contains a low dose of the steroid prednisolone and amoxapine. The target product profile for CRx-119 is to selectively amplify certain elements of prednisolone's anti-inflammatory and immunomodulatory effects, without replicating steroid toxicity.
Cơ Chế Tác Dụng : CRx-119 is a novel synergistic combination drug candidate discovered using the CombinatoRx combination High Throughput Screening (cHTS(TM)) technology with potential therapeutic use in a broad range of immuno-inflammatory conditions. CRx-119 is a combination of a low dose of the steroid prednisolone, 3mg, and amoxapine. Amoxapine acts by decreasing the reuptake of norepinephrine and serotonin (5-HT). Glucocorticoids such as prednisolone can inhibit leukocyte infiltration at the site of inflammation, interfere with mediators of inflammatory response, and suppress humoral immune responses. The antiinflammatory actions of glucocorticoids are thought to involve phospholipase A2 inhibitory proteins, lipocortins, which control the biosynthesis of potent mediators of inflammation such as prostaglandins and leukotrienes. Prednisolone reduces inflammatory reaction by limiting the capillary dilatation and permeability of the vascular structures. These compounds restrict the accumulation of polymorphonuclear leukocytes and macrophages and reduce the release of vasoactive kinins. Recent research suggests that corticosteroids may inhibit the release of arachidonic acid from phospholipids, thereby reducing the formation of prostaglandins. Prednisolone is a glucocorticoid receptor agonist. On binding, the corticoreceptor-ligand complex translocates itself into the cell nucleus, where it binds to many glucocorticoid response elements (GRE) in the promoter region of the target genes. The DNA bound receptor then interacts with basic transcription factors, causing an increase or decrease in expression of specific target genes, including suppression of IL2 (interleukin 2) expression.
Độc Tính : CRx-119 was generally well tolerated and there were no drug-related serious adverse events reported. The most common adverse event observed with CRx-119 was drowsiness, a known side-effect of amoxapine.
Chỉ Định : Investigated for use/treatment in periodontal disease and rheumatoid arthritis.
