Michael Levy, MD, PhD – Johns Hopkins University:
We recognize that NMO patients have a range of relapse rates. Some patients present with multiple relapses, one after the other, and other patients can go years between relapses. We put all of our data together in the U.S., and we found that, on average, the median relapse rate is once every seven months untreated and once every 15 months on treatment. So despite treatment, there’s still a relapse rate of about once every 15 months.
