    From the start of RAP-219 treatment through 8 weeks after last dose, up to Week 112

Secondary Outcomes (13)

  • Percent change in clinical seizure frequency

    Throughout the open-label period until 8 weeks after the last dose, up to Week 112, compared to the pre-treatment baseline period.

  • Clinical seizure 25%, 50%, 75%, and 100% responder proportions

    Throughout the open-label period until 8 weeks after the last dose, up to Week 112, compared to the pre-treatment baseline period.

  • Change in clinical seizure-free day frequency

    Throughout the open-label period until 8 weeks after the last dose, up to Week 112, compared to the pre-treatment baseline period.

  • Longest clinical seizure-free interval

    Throughout the open-label period until 8 weeks after the last dose, up to Week 112, compared to the pre-treatment baseline period.

  • Time to pre-randomization clinical seizure count

    Throughout the open-label period until 8 weeks after the last dose, up to Week 112, compared to the pre-treatment baseline period.

  • +8 more secondary outcomes
