Research in multiple sclerosis
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 the disease better and in the future may help to find new treatments.
Research directions on MS treatments include investigations of MS pathogenesis and heterogeneity; research of more effective, convenient, or tolerable new treatments for RRMS; creation of therapies for the progressive subtypes; neuroprotection strategies; and the search for effective symptomatic treatments.
Several previous MS variants have been recently separated from MS after the discovery of a specific auto-antibody, specially autoantibodies against AQP4, MOG and Neurofascin proteins.
Previously recognized variants of MS like Optic-Spinal MS is now classified as a phenotype of the anti-AQP4 spectrum, and some tumefactive cases of MS as anti-MOG associated encephalomyelitis. Some researchers think that there could exist also an overlapping between Anti-NMDA receptor encephalitis cases and neuromyelitis optica or acute disseminated encephalomyelitis.
The following previous MS variants are now considered apart from MS:
Advancements during the last decades have led to the recent approval of several oral drugs. In March 2019 for example the Food and Drug Administration approved cladribine tablets (Mavenclad) to treat relapsing forms of multiple sclerosis (MS) in adults, to include relapsing-remitting disease and active secondary progressive disease. These drugs are expected to gain in popularity and frequency of use at the expense of previously existing therapies.
Further oral drugs are still under investigation, the most notable example being laquinimod, which was announced in August 2012 to be the focus of a third phase III trial after mixed results in the previous ones. Early trials of the female sex hormone estriol, led in part by Rhonda Voskuhl, have generated interest in reducing symptoms in women with RRMS. Similarly, several other studies are aimed to improve efficacy and ease of use of already existing therapies through the use of novel preparations.
Such is the case the PEGylated version of interferon-β-1a, that has a longer life than normal interferon and therefore it is being studied if given at less frequent doses has a similar efficacy than the existing product. Peginterferon beta-1a was approved for use in the United States in August 2014.
