new treatment for osteoarthritis 2021

common in the older adult population, oa is associated with loss of cartilage over time. they examined the mir-455 parent molecule that is an unusual one in that it creates two different strands of functional mirna, 5p and 3p. individual mirnas target a repertoire of genes that contain their specific binding sequence in the gene message. a previous study has shown that deleting the mir-455-3p strand in mice causes degeneration of the mouse knee cartilage but the details, and the effect of the 5p strand, remained unclear. “our interest in the topic was aroused by this lack of information and reinforced by the exceptionality of mir-455 in generating two distinct strands of mirna that both have biological effects.” the researchers examined mir-455 levels in human cartilage samples and found that individuals with oa had significantly lower amounts of this mirna. “we performed a detailed genetic screening and found that the gene message for a protein called hypoxia-inducible factor-2α (hif-2α) was amongst the targets of mir-455.”

hif-2α is a protein that is involved in the breakdown of cartilage. “our findings not only help us better understand the biology of cartilage regulation and oa pathogenesis, but also show that mir-455 has the potential to be developed into a novel therapeutic method for treating oa,” explains ito. this study provides strong support for using both strands of mir-455 in such a manner for oa. use this form if you have come across a typo, inaccuracy or would like to send an edit request for the content on this page. for general feedback, use the public comments section below (please adhere to guidelines). the information you enter will appear in your e-mail message and is not retained by medical xpress in any form. you can unsubscribe at any time and we’ll never share your details to third parties.

osteoarthritis (oa) can be viewed as the structural and functional failure of the synovial joint organ (loeser et al., 2012). the inflammatory mediators can be detected in both synovial fluid and serum in oa patients, indicating that inflammation does play a significant role in the pathogenesis of oa (legrand et al., 2001). however, the results from two recent phase ii clinical studies to assess the efficacy of lutikizumab in patients with hand oa and knee oa were unsatisfactory (fleischmann et al., 2019; kloppenburg et al., 2019). a pilot study investigated the efficacy and tolerability of ia injection of infliximab in erosive hand oa (fioravanti et al., 2009). a 12-month, double-blind, randomized controlled trial evaluated the efficacy and safety of adalimumab in controlling structural damage in patients with erosive hand oa (verbruggen et al., 2012). the balance of wnt pathway activity is integral for regulating the differentiation of progenitor cells in the joint and maintaining cartilage homeostasis (lories et al., 2013; thysen et al., 2015). cathepsin-k is the predominant cysteine cathepsin in the skeleton and it plays an important role in the resorption of cartilage and bone (dejica et al., 2008). a randomized, double-blind, placebo-controlled phase i b proof-of-concept trial evaluated the efficacy and safety of ia injection of sprifermin (10, 30, and 100 μg) in patients with symptomatic knee oa (lohmander et al., 2014). two randomized, double-blind, placebo-controlled phase ii studies to evaluate the safety and efficacy of ia injection of gec-tgf-β1 in patients with knee oa (cherian et al., 2015; ha et al., 2015). increased subchondral bone resorption and bone turnover contribute to the pathogenesis of oa (karsdal et al., 2014). it promotes the proliferation and survival of osteoblasts, which is a bone anabolic therapy for osteoporosis (sampson et al., 2011). a phase iib/iii clinical trial assessed the efficacy, tolerability, and joint safety of fasinumab in patients with hip and/or knee oa (dakin et al., 2019). the anti-ngf treatment undoubtedly provides great potential for improving the pain and function of patients with severely symptomatic oa, but it carries the risk of aggravating the structural progression of oa (miller et al., 2017). the oa patients in the progressed periods are potentially more responsive to interventions, and these patients might be recruited in dmoad trials to assess the efficacy of a new drug in the future. long-term rcts are still needed to confirm the safety and efficacy of these novel oa pharmacotherapy medicines. overexpression of active tgf-beta-1 in the murine knee joint: evidence for synovial-layer-dependent chondro-osteophyte formation. subcutaneous tanezumab for osteoarthritis of the hip or knee: efficacy and safety results from a 24-week randomised phase iii study with a 24-week follow-up period. a high-throughput quantification method of curcuminoids and curcumin metabolites in human plasma via high-performance liquid chromatography/tandem mass spectrometry. preliminary results of a phase ii randomized study to determine the efficacy and safety of genetically engineered allogeneic human chondrocytes expressing tgf-β1 in patients with grade 3 chronic degenerative joint disease of the knee. adalimumab in patients with hand osteoarthritis refractory to analgesics and nsaids: a randomised, multicentre, double-blind, placebo-controlled trial. a randomized, double-blind study of amg 108 (a fully human monoclonal antibody to il-1r1) in patients with osteoarthritis of the knee. mechanisms and therapeutic implications of cellular senescence in osteoarthritis. effectiveness of non-steroidal anti-inflammatory drugs for the treatment of pain in knee and hip osteoarthritis: a network meta-analysis. a small-molecule inhibitor of the wnt pathway (sm04690) as a potential disease modifying agent for the treatment of osteoarthritis of the knee. serum levels of vitamin d, sunlight exposure, and knee cartilage loss in older adults: the tasmanian older adult cohort study. intra-articular sprifermin reduces cartilage loss in addition to increasing cartilage gain independent of location in the femorotibial joint: post-hoc analysis of a randomised, placebo-controlled phase ii clinical trial. safety of opioids in osteoarthritis: outcomes of a systematic review and meta-analysis. a multicenter, single-blind, phase iia clinical trial to evaluate the efficacy and safety of a cell-mediated gene therapy in degenerative knee arthritis patients. effect of intra-articular sprifermin vs placebo on femorotibial joint cartilage thickness in patients with osteoarthritis.
