Design outcomes

Primary

MeasureTime frame
Main Objective: To confirm non-inferiority of the once-daily application of the sustained release study preparation (SR-OXC) compared to the twice-daily immediate release reference preparation Timox®(IM-OXC).;Secondary Objective: Proportion of patients remaining seizure-free during the 12 weeks of randomised treatment; proportion of adverse events;Primary end point(s): The primary endpoint for statistical analysis is the time-to exit (failure time), i.e. the time when one of the exit creiteria is fulfilled. It is of no clinical relevance for which reason the patient stopped continuing the treatment.
