Drug companies weren't interested in estriol because it isn't a patented chemical, Voskuhl says. So she turned to the National Institutes of Health, the National Multiple Sclerosis Society and foundations, including one set up by the family of Melissa Sherak Glasser.
Ultimately, Voskuhl got the millions of dollars she needed to conduct a two-year trial of estriol in women who also were taking the widely used MS drug Copaxone. The success of that trial clears the way for a much larger study that can be submitted to the Food and Drug Administration for approval.
