Prespecified exploratory analysis

Of all NMOSD trials, CHAMPION-NMOSD had the largest percentage of patients with prior rituximab use1-7

36.2% (21 of 58) of patients had prior exposure to rituximab and at least 1 relapse in the 12 months prior to screening1*

  • In a prespecified exploratory analysis, 20 of the 21 patients treated with ULTOMIRIS were previously treated with rituximab in the year before screening (placebo, n=17)1†
Zero

RELAPSES WERE SEEN IN THE CHAMPION-NMOSD STUDY1‡

In patients with prior rituximab use, ULTOMIRIS reduced the risk of relapse by 93.7% compared with placebo1

  • The last rituximab dose permitted was >3 months prior to screening1

CHAMPION-NMOSD study limitation: Results or clinical outcomes should be interpreted with caution since this was a prespecified exploratory analysis.

Post hoc analysis

Transitioning to a complement inhibitor after previous exposure to rituximab8

In the post hoc analysis, patients had previous exposure within 1 year prior to enrolling in CHAMPION-NMOSD and PREVENT8

Among the 154 patients receiving complement inhibitors, 38 patients were exposed to rituximab within the year prior to treatment8

6.5 (2.0) months was the mean (SD) time from the last rituximab dose to the first complement inhibitor dose8

5.4 (2.0) months was the mean (SD) time from the last rituximab dose to the first meningococcal vaccination8

There are currently no published guidelines on transitioning from rituximab to ULTOMIRIS in patients with NMOSD9

CHAMPION-NMOSD study limitation: Results or clinical outcomes should be interpreted with caution since this was a prespecified post hoc analysis.

*Patients with prior exposure to rituximab may have been on additional concurrent therapies.1

One of the 21 patients exposed to rituximab was exposed >12 months prior to screening.1

Observed during the primary treatment period, which ended when the last patient completed 50 weeks and represented a median study duration of 73.5 weeks (min 13.7, max 117.7).10
