Outcome
Type Measure Description Time frame Safety issue
Primary Response Ratio of Gabapentin in Japanese Pediatric Patients With Partial Seizures The Response Ratio calculated by the following equation was assessed as the primary endpoint: R Ratio = (T-B) / (T+B) where T is seizure frequency per 28 days (i.e., the number of seizures per 28 days) calculated from the total number of seizures for the 12-week treatment period, and B is seizure frequency per 28 days (i.e., the number of seizures per 28 days) calculated from the total number of seizures for the 6-week baseline period. 12 weeks
Secondary Responder Rate Responder Rate was defined as the percentage of subjects with a 50% or greater reduction in the seizure frequency per 28 days for the 12-week treatment period in comparison with the frequency per 28 days for the 6-week baseline period. 12 weeks
Secondary Percent Change in Seizure Frequency (PCH) PCH calculated by the following equation was assessed as secondary endpoint: PCH = 100 (T-B) / B where T is seizure frequency per 28 days (i.e., the number of seizures per 28 days) calculated from the total number of seizures for the 12-week treatment period, and B is seizure frequency per 28 days (i.e., the number of seizures per 28 days) calculated from the total number of seizures for the 6-week baseline period. 12 weeks
