    Time frame: Baseline to 15, 30, 45, 60 mins and 2, 3, and 4 hours post-dose for each of the 3 treatment period dosing visits.

    For the primary central tendency analysis, the changes from baseline (ΔQTcF) were compared between APL-130277 and placebo (ΔΔQTcF). Baseline was defined as the mean of the 9 ECGs (3 sets of triplicate ECGs) recorded at baseline (P1V1). In case any of the 9 ECGs were missing, the baseline was defined as the mean of the available baseline values. The post-dose ECGs were evaluated at 15, 30, 45 and 60 minutes (mins) and 2, 3 and 4 hours post-dose at each of the 3 treatment period dosing visits during the Randomized Crossover Assessment Phase. For each of the time points, an average value was calculated based on the 3 (or all available) ECGs. These average values were used in all change from baseline calculations.

If the patient did not turn fully 'ON' within 90 minutes the duration of 'ON' was defined as zero minutes. If the patient turned fully 'ON' and did not turn 'OFF' by 90 minutes, the data was censored at 90 minutes minus the time when the patient turned fully 'ON'.

    The median duration of a full 'ON' response during the Dose Titration Phase following the highest tolerated APL-130277 dose level (indicated as Day 2) and the lowest APL-130277 dose resulting in a full 'ON' (indicated as Day 1) are presented. The median duration of 'ON' on Day 1 and Day 2 was calculated using the Kaplan-Meier method.
