Results of Phase II Study Show Improvement in MS Symptoms
Bethesda, MD - Combining the estrogen hormone estriol with Copaxone, a drug indicated for the treatment of patients with relapsing forms of multiple sclerosis (MS), may improve symptoms in patients with the disorder, according to preliminary results from a clinical study of 158 patients with relapsing remitting multiple sclerosis (RRMS).
The findings were presented by Rhonda Voskuhl, M.D., from the University of California, Los Angeles, at the American Academy of Neurology Annual Meeting in Philadelphia. The study was funded by the National Institute of Neurological Disorders and Stroke (NINDS), part of the National Institutes of Health; and the National Multiple Sclerosis Society.
“While these results are encouraging, the results of this Phase II study should be considered preliminary as a larger study would be needed to know whether benefits outweigh the risks for persons affected by MS. At present, we cannot recommend estrogen as part of standard therapy for MS. We encourage patients to talk with their doctors before making any changes to their treatment plans,” said Walter Koroshetz, M.D., deputy director of NINDS.
Numerous laboratory studies have suggested that estrogen may have neuroprotective effects and may help decrease inflammation, which occurs in MS. In addition, it has been reported that MS patients experience improvement in symptoms during the phase of pregnancy when levels of estrogen increase. However, studies looking at the effects of estrogen therapy on women’s health have shown mixed results. Estriol, the form of estrogen examined in this study, is only produced in the body during pregnancy. Continue>
