| Primary | Percent Change From Baseline in 28-day Seizure Frequency at Week 21. | The seizures were recorded by the participants, by a family member, by a caregiver, or by a legal guardian and documented in a daily seizure diary. Participant's 28-day seizure frequency of all partial seizure was assessed during double blind (TP + MP) phase compared with baseline. Total partial seizure is defined as the total number of (simple partial seizure + complex partial seizure + secondary generalized tonic clonic seizure [SGTC]). | Full analysis set (FAS) included all randomized participants who had received at least 1 blinded dose of study drug and had at least 1 baseline and post baseline primary efficacy evaluation. | Posted | | Median | Full Range | percent change | | 6 weeks Baseline, 21 weeks through End of MP for 27 weeks | | | | ID | Title | Description |

| OG000 | Pregabalin | Pregabalin was initiated at 150 mg/day [50 mg capsules orally three times a day (TID)] for 1 Week followed by pregabalin 300 mg/day (100 mg TID) orally TID up to Week 5 in the Titration Phase (TP). Participants who had adequate seizure control (adequate: >=50% reduction in seizures) with acceptable tolerability with pregabalin 300 mg/day in TP, continued same dose until the end of TP (Week 9) and then entered the maintenance phase (MP) on this dose. If seizure control was inadequate, the pregabalin dose was escalated to 450 mg/day orally (150 mg TID) from Weeks 5 through 9. If the participants had adequate seizure control with acceptable tolerability on this dose, then they entered the MP on this dose. If there was inadequate seizure control at the end of Week 9, the dose was escalated a final time to 600 mg/day (200 mg TID) at which time they entered the MP. | | OG001 | Gabapentin | Gabapentin was initiated at 300 mg/day [100 mg capsules orally three times a day (TID)] followed by gabapentin 600 mg/day (200 mg TID) on Day 3. At the end of Week 1 (Day 7), the dose was increased to 1200 mg/day (400 mg TID) and remained on this dose for the next 4 weeks). Participants who had adequate seizure control (>=50% reduction in seizure frequency) with acceptable tolerability during this initial 5-week period, remained on this dose until the end of theTP (Week 9), then entered the MP on this dose. If seizure control was inadequate, the gabapentin dose was escalated to 1500 mg/day (500 mg TID) during Weeks 5 through 9. If they had adequate seizure control with acceptable tolerability on this dose, they entered the MP on this dose. If there was inadequate seizure control at the end of Week 9, the dose was escalated a final time to 1800 mg/day (600 mg TID), at which time they entered the MP. |
