Study Endpoints
Primary Endpoints
Number of participants with treatment emergent adverse events (AEs).
Baseline until the end of study, approximately 2.5 years (Dec-2021).

Treatment-emergent adverse events and serious adverse events will be grouped by MedDRA System Organ Class, dose level at onset, time on drug at onset, and relationship to dose titration.

Incidence of Treatment-Emergent Adverse Events and Serious Adverse Events
Baseline, Week 2, Month 1, Month 2 Visits, with bimonthly follow up for up to 16 months.

There were two treatment arms analyzed for events in the study. All subjects that participated in the PK study were part of the transition group and not analyzed separately for adverse events. Treatment-Emergent Adverse Events and Serious Adverse Events will be grouped by MedDRA System Organ Class, dose level, time on drug, and relationship to dose titration
