Tanezumab (INN, codenamed RN624) is a monoclonal antibody against nerve growth factor as a treatment for pain via a novel mechanisms different from conventional pain-killer drugs. [1] Tanezumab was discovered and developed by Rinat Neuroscience [2] and was acquired by Pfizer in 2006.
In 2009 there was a Phase III trial for knee pain due to osteoarthritis (OA). [3] Another Phase III trial for hip pain in OA [4] was halted in June 2010 when some patients needed hip replacement. [5]
Tanezumab is undergoing Phase II clinical trials for the treatment of various pain entities, including chronic low back pain, bone cancer pain, and interstitial cystitis. [6]
In March 2012, the Anti-NGF Testing - FDA Committee voted in favor of a continuation of the development of nerve-blocking medications, as long as certain safety precautions were observed. [7] [8]
A Phase III trial published in 2013 found tanezumab was superior to placebo for painful hip osteoarthritis. [9]
At February 19, 2019 the co-development partners - Eli Lilly and Pfizer - announced that treatment with tanezumab 10 mg met the primary endpoint, demonstrating a statistically significant improvement in chronic low back pain at 16 weeks compared to placebo (however, 5 mg arm demonstrated a numerical improvement in pain, but did not reach statistical significance compared to placebo at the week 16 analysis). [10]
On 16 September 2021, the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) recommended the refusal of the marketing authorization for tanezumab (Raylumis), a medicine intended for the treatment of pain associated with osteoarthritis. [11]
On 25 March 2021, the FDA Joint Arthritis Advisory Committee and Drug Safety and Risk Management Advisory Committee voted 1 to 19 against the question : on whether the proposed risk evaluation and mitigation strategy (REMS) for tanezumab will ensure its benefits outweigh its risks. [12]
Infliximab, a chimeric monoclonal antibody, sold under the brand name Remicade among others, is a medication used to treat a number of autoimmune diseases. This includes Crohn's disease, ulcerative colitis, rheumatoid arthritis, ankylosing spondylitis, psoriasis, psoriatic arthritis, and Behçet's disease. It is given by slow injection into a vein, typically at six- to eight-week intervals.
Ocrelizumab, sold under the brand name Ocrevus, is a medication used for the treatment of multiple sclerosis (MS). It is a humanized anti-CD20 monoclonal antibody. It targets CD20 marker on B lymphocytes and is an immunosuppressive drug. Ocrelizumab binds to an epitope that overlaps with the epitope to which rituximab binds.
Reslizumab is a humanized monoclonal antibody against human interleukin-5 (IL-5). Reslizumab binds specifically to IL-5, a key cytokine responsible for the differentiation, maturation, recruitment and activation of human eosinophils. By binding to human IL-5, it blocks its biological function; consequently survival and activity of eosinophils are reduced. The benefits with reslizumab are its ability to reduce the exacerbation rate and improve lung function and asthma-related quality of life in patients with severe eosinophilic asthma and with at least one previous asthma exacerbation in the preceding year. The most common side effects are increased blood creatine phosphokinase, myalgia and anaphylactic reactions.
Canakinumab, sold under the brand name Ilaris, is a medication for the treatment of systemic juvenile idiopathic arthritis, active Still's disease, including adult-onset Still's disease, gout flares. It is a human monoclonal antibody targeted at interleukin-1 beta. It has no cross-reactivity with other members of the interleukin-1 family, including interleukin-1 alpha.
Tolerx, Inc. was a biopharmaceutical company headquartered in Cambridge, Massachusetts. The company was focused on discovering and developing new therapies designed to treat patients by reprogramming the immune system, allowing for long-term remission of immune-related diseases after a short course of therapy. Targeted diseases include type 1 diabetes, rheumatoid arthritis, Inflammatory bowel disease (IBD), cancer, chronic and viral diseases. In 2008, Tolerx was named one of Fierce Biotech’s Fierce 15. In October 2011, Tolerx was shut down due to an unsuccessful Phase III trial in patients recently diagnosed with Type 1 diabetes.
Tofacitinib, sold under the brand Xeljanz among others, is a medication used to treat rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, polyarticular course juvenile idiopathic arthritis, and ulcerative colitis. It is a janus kinase (JAK) inhibitor, discovered and developed by the National Institutes of Health and Pfizer.
Fulranumab is a monoclonal antibody against nerve growth factor. It was designed for the treatment of pain.
Ixekizumab, sold under the brand name Taltz, is an injectable medication for the treatment of autoimmune diseases. Chemically, it is a form of a humanized monoclonal antibody. The substance acts by binding interleukin 17A and neutralizing it, reducing inflammation.
Fasinumab is a human monoclonal antibody designed for the treatment of acute sciatic pain.
Helixmith Co. LTD. is a biotechnology company located in Seoul, South Korea with US presence in San Diego. The company has an extensive gene therapy pipeline, including a non-viral plasmid DNA program for neuromuscular and ischemic disease, a CAR-T program targeting several different types of solid tumors, and an AAV vector program targeting neuromuscular diseases. Helixmith’s lead gene is Engensis (VM202), currently in phase III diabetic peripheral neuropathy (DPN) in the US. Engensis (VM202) is a plasmid DNA designed to simultaneously express two isoforms of hepatocyte growth factor (HGF), HGF 728 and HGF 723. In addition to DPN, Engensis is also being studied in diabetic foot ulcers (DFU), amyotrophic lateral sclerosis (ALS), coronary artery disease (CAD), claudication, and Charcot-Marie-Tooth disease (CMT).
Tildrakizumab, sold under the brand names Ilumya and Ilumetri, is a monoclonal antibody designed for the treatment of immunologically mediated inflammatory disorders. It is approved for the treatment of adult patients with moderate-to-severe plaque psoriasis in the United States and the European Union.
Guselkumab, sold under the brand name Tremfya, is a monoclonal antibody against interleukin-23 used for the treatment of plaque psoriasis.
A significant amount of research has been performed on glycosaminoglycans, especially glucosamine and chondroitin, for the treatment of arthritis. These compounds are commonly marketed as nutritional supplements and numerous 'soft therapeutic claims' are made about their health benefits - especially in aging populations. Since glucosamine is a precursor for glycosaminoglycans, and glycosaminoglycans are major components of cartilage, ingesting glucosamine might nourish joints, and thereby alleviate arthritis symptoms. Authoritative opinions on the actual therapeutic value of these compounds have been very mixed.
Rinat Neuroscience Corporation was a privately held biotechnology company that discovered and developed antibody-based drugs, including:
Risankizumab, sold under the brand name Skyrizi, is a humanized monoclonal antibody used for the treatment of plaque psoriasis, psoriatic arthritis, and Crohn's disease. It is designed to target interleukin 23A (IL-23A). It is given by subcutaneous injection.
A disease-modifying osteoarthritis drug (DMOAD) is a disease-modifying drug that would inhibit or even reverse the progression of osteoarthritis. Since the main hallmark of osteoarthritis is cartilage loss, a typical DMOAD would prevent the loss of cartilage and potentially regenerate it. Other DMOADs may attempt to help repair adjacent tissues by reducing inflammation. A successful DMOAD would be expected to show an improvement in patient pain and function with an improvement of the health of the joint tissues.
Nerve growth factor (NGF) inhibitors are a class of compounds that inhibit the action of the neurotrophin nerve growth factor by targeting NGF molecules or NGF receptors. NGF inhibitors have demonstrated therapeutic potential in treatment of certain chronic pain disorders, including osteoarthritis, and chronic lower back pain. Two NGF inhibitors are undergoing clinical trials as potential treatments for pain disorders.
Frunevetmab, sold under the brand name Solensia, is a medication used to treat pain associated with osteoarthritis in cats.
