In this two-year study, patients received Copaxone along with 8 milligrams per day of estriol or placebo pills. The primary goal of the trial was to determine if estriol helped decrease the number of relapses experienced by RRMS patients who were also taking Copaxone.
Researchers found that at 12 months, estrogen combination therapy was associated with a greater reduction in relapse rates compared to Copaxone and placebo. However, at 24 months, the difference between the treatment groups was not as great as it was at 12 months.
"The findings presented by Dr. Voskuhl suggest that there may be benefits to supplementing Copaxone therapy with estrogen. A longer study, with more patients, would be necessary to definitively validate these provocative, although early, findings," said Dr. Koroshetz.
