VIDEO: Efficacy of DMTs decreases with age



The efficacy of immunomodulatory disease-modifying therapies for multiple sclerosis decreases with age, and high-efficacy drugs do a better job of inhibiting MS disability compared with low-efficacy drugs only in patients younger than 40.5 years.

Those are the key conclusions from a meta-analysis of the age-dependent efficacy of MS treatments that was published in the November 2017 issue of Frontiers in Neurology. In a video interview, Ann Marie Weideman, lead study author, discussed highlights from the meta-analysis at the meeting held by the Americas Committee for Treatment and Research in Multiple Sclerosis. The meta-analysis drew from more than 28,000 individuals with MS participating in 38 trials of 13 categories of immunomodulatory drugs.

Ms. Weideman is an IRTA Fellow at the National Institute of Neurological Disorders and Stroke, Bethesda, Md. She reported that study coauthor Bibiana Bielekova, MD, is coinventor of several patents related to daclizumab.
