## Resource

In the second episode of this series, Dr. Justin Abbatemarco and Dr. Benjamin P. Trewin discuss what was found in non-steroidal maintenance therapies. Read more about this abstract on the AAN website . Show transcript: Dr. Justin Abbatemarco: Hello and welcome back. This is Justin Abbatemarco from the Cleveland Clinic. And we're joined by Ben Trewin on his abstract maintenance immunotherapy and MOGAD, early steroid benefit, dose thresholds and disability risk. Ben, in our first episode we really talked about corticosteroids, but your paper and abstract looked at other therapies. What did you find in those non-steroidal maintenance therapies? Dr. Benjamin Trewin: In addition to looking at oral corticosteroid therapies, we also looked at B-cell depleting therapies, namely rituximab and ocrelizumab, and intravenous immunoglobulin and steroid-sparing therapies, namely azathioprine and mycophenolate predominantly, I suppose a couple on methotrexate. Now, what we found, it's important to note that we were able to tease apart the effects of all these drugs with our Cox proportional hazard model chops up, follow up into distinct intervals with different combinations and permutations of these medications and their different doses in a more granular way than is allowed by previous techniques like incident rate ratios when we compare pre and post annualized relapse rate, and we think this is a strength of the study. With this methodological strength, we were able to see that steroid-sparing therapies, despite 334 patient years of data, do not appear to have any independent benefit with respect to time to next relapse. The estimate of effect there was 1.06. And then for time to confirm sustained disability, there was also no confidence signal, the confidence interval being 0.15 to…
