Study Endpoints
Primary Endpoints
Median Percent Change in Seizure Frequency
End of double-blind treatment period (end of week 14) vs Baseline

Median percent change in seizure frequency and ≥ 50% seizure frequency reduction responder rates:

Incidence of treatment-emergent adverse events (TEAEs)
From the start of RAP-219 treatment through 8 weeks after last dose, up to Week 112
Young Mania Rating Scale (YMRS)
Baseline to End of Treatment at Week 3

The YMRS is a clinician administered scale that consists of 11 items used to assess the severity of manic symptoms (total scores range from 0 to 60). The higher the YMRS score, the more severe the subject's symptoms of mania.

Change in long episode frequency during the treatment period compared to pre-treatment baseline: Responder proportion, Percent Change Percent change
Screening until 5 months after enrollment

Change in long episode frequency per 28-day period during the treatment period compared to baseline

Secondary Endpoints
≥50% seizure frequency reduction responder rates
End of double-blind treatment period (end of week 14) vs Baseline.
Longest Seizure Free Interval
Across the entire 14-week double-blind treatment period
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.
