Multiple sclerosis (MS) is a demyelinating disease in which the insulating covers of nerve cells in the brain and spinal cord are damaged. This damage disrupts the ability of parts of the nervous system to transmit signals, resulting in a range of signs and symptoms, including physical, mental, and sometimes psychiatric problems. Specific symptoms can include double vision, blindness in one eye, muscle weakness and trouble with sensation or coordination. MS takes several forms, with new symptoms either occurring in isolated attacks or building up over time. Between attacks, symptoms may disappear completely; however, permanent neurological problems often remain, especially with the advancement of the disease.
Biogen Inc. is an American multinational biotechnology company based in Cambridge, Massachusetts, specializing in the discovery, development, and delivery of therapies for the treatment of neurological diseases to patients worldwide.
Daclizumab is a therapeutic humanized monoclonal antibody which was used for the treatment of adults with relapsing forms of multiple sclerosis (MS). Daclizumab works by binding to CD25, the alpha subunit of the IL-2 receptor of T-cells.
Élan Corporation plc was a major drugs firm based in Dublin, Ireland, which had major interests in the United States. It was listed on the New York Stock Exchange as ELN, the Irish Stock Exchange as ELN.I, and the London Stock Exchange as ELN.L. In 2013, the company merged with Perrigo to form Perrigo Company PLC.
Natalizumab, sold under the brand name Tysabri among others, is a medication used to treat multiple sclerosis and Crohn's disease. It is a humanized monoclonal antibody against the cell adhesion molecule α4-integrin. It is given by intravenous infusion every 28 days. The drug is believed to work by reducing the ability of inflammatory immune cells to attach to and pass through the cell layers lining the intestines and blood–brain barrier. Natalizumab has proven effective in treating the symptoms of both diseases, preventing relapse, vision loss, cognitive decline and significantly improving quality of life in people with multiple sclerosis, as well as increasing rates of remission and preventing relapse in multiple sclerosis.
Fontolizumab is a humanized monoclonal antibody and an immunosuppressive drug for the treatment of auto-immune diseases like Crohn's disease. A phase II clinical trial investigating the use for rheumatoid arthritis was terminated because the first phase did not meet the endpoint.
Ocrelizumab, sold under the brand name Ocrevus, is a humanized anti-CD20 monoclonal antibody. It targets CD20 marker on B lymphocytes and hence is an immunosuppressive drug. Ocrelizumab binds to an epitope that overlaps with the epitope to which rituximab binds.
Priliximab is a human-mouse chimeric anti-CD4 monoclonal antibody. It has been tested on patients with Crohn's disease and multiple sclerosis but has not yet received U.S. Food and Drug Administration licensing. The patent belongs to the biotechnology company Centocor.
Research in multiple sclerosis may find new pathways to interact with the disease, improve function, curtail attacks, or limit the progression of the underlying disease. Many treatments already in clinical trials involve drugs that are used in other diseases or medications that have not been designed specifically for multiple sclerosis. There are also trials involving the combination of drugs that are already in use for multiple sclerosis. Finally, there are also many basic investigations that try to understand better the disease and in the future may help to find new treatments.
Zaurategrast (CDP323) is a small-molecule prodrug antagonist of the vascular cell adhesion molecule 1 (VCAM-1) binding to α4-integrins. It was originally developed by the British biopharmaceutical company Celltech plc. and was a putative new drug for oral treatment of multiple sclerosis.
Leucine rich repeat and Immunoglobin-like domain-containing protein 1 also known as LINGO-1 is a protein which is encoded by the LINGO1 gene in humans. It belongs to the family of leucine-rich repeat proteins which are known for playing key roles in the biology of the central nervous system. LINGO-1 is a functional component of the Nogo receptor also known as the reticulon 4 receptor.
Figitumumab is a monoclonal antibody targeting the insulin-like growth factor-1 receptor that was investigated for the treatment of various types of cancer, for example adrenocortical carcinoma and non-small cell lung cancer (NSCLC).
Briakinumab (ABT-874) is a human monoclonal antibody being developed by Abbott Laboratories for the treatment of rheumatoid arthritis, inflammatory bowel disease, and multiple sclerosis. As of 2011 drug development for psoriasis has been discontinued in the U.S. and Europe.
Amatuximab is a chimeric monoclonal antibody designed for the treatment of cancer.
Carlumab is a discontinued human recombinant monoclonal antibody that targets human CC chemokine ligand 2 (CCL2)/monocyte chemoattractant protein (MCP1). Carlumab was under development for use in the treatment of oncology and immune indications and was studied for application in systemic sclerosis, atherosclerosis, diabetic nephropathy, liver fibrosis and type 2 diabetes.
Ozanezumab is a monoclonal antibody designed for the treatment of ALS and multiple sclerosis.
GSK2831781 is a monoclonal antibody being developed by GlaxoSmithKline (GSK) for autoimmune diseases. The antibody targets the T cell activation marker LAG-3, which is mainly expressed in inflamed tissues. In GSK's March 2015 Product development pipeline document the antibody is listed under 'Immuno-inflammation' candidates. GSK2831781 entered a Phase I clinical trial in psoriasis early in 2015.
Opicinumab (BIIB033) is a fully human monoclonal antibody designed for the treatment of multiple sclerosis, acute optic neuritis (AON), and other associated demyelinating diseases. A biologic drug, it is designed to function as a LINGO-1 protein antagonist, known as “Anti-Lingo-1”.
This page describes the process and status of pharmaceuticals for treating multiple sclerosis (MS).
Otilimab is a fully human antibody which has been developed by the biotechnology company MorphoSys. It can also be referred to as HuCAL antibody, HuCAL standing for Human Combinatorial Antibody Library and being a technology used to generate monoclonal antibodies. Otilimab is directed against the granulocyte-macrophage colony stimulating factor (GM-CSF), a monomeric glycoprotein functioning as a cytokine promoting both proliferation and activation of macrophages and neutrophils.
