Trial Outcomes & Findings for Non-Interventional Study With LYRICA (Pregabalin) In Patients With Epilepsy As Adjunctive Therapy Of Partial Seizures To Reduce Seizure Frequency (NCT NCT00684424)

NCT ID: NCT00684424

Last Updated: 2021-02-10

Results Overview

Responders: number of subjects with a 50 percent (%) or greater reduction in partial seizure frequency from Baseline to Final visit. Seizure frequency in treatment period = total number of partial seizures in maintenance treatment phase \* 28 divided by total number of days in the maintenance treatment phase. Missing category includes subjects with missing attack date, insufficient length of treatment period or no seizures in both baseline and treatment periods. Subjects with zero seizures in the baseline period and some seizures in the treatment period were treated as non-responders.

PRIMARY outcome

Timeframe: Baseline through Week 16

Population: Full Analysis Set: all subjects who received at least 1 dose of study drug and had at least 1 efficacy measurement.

Responders: number of subjects with a 50 percent (%) or greater reduction in partial seizure frequency from Baseline to Final visit. Seizure frequency in treatment period = total number of partial seizures in maintenance treatment phase \* 28 divided by total number of days in the maintenance treatment phase. Missing category includes subjects with missing attack date, insufficient length of treatment period or no seizures in both baseline and treatment periods.

SECONDARY outcome

Timeframe: Baseline through Week 16 (Final Visit )

Population: FAS. Subjects who discontinued less than 4 weeks into the treatment period or with missing date of the attack were excluded from analyses.

Change in 28-day partial seizure frequency between the baseline period and treatment period. Baseline period = the 4 weeks (28 days) prior to Baseline visit. Treatment period = last 12 weeks (84 days) of the study (maintenance treatment phase excluding 4-week titration phase). Seizure frequency in baseline period = total number of partial seizures in baseline phase \* 28 divided by total number of days in the baseline phase. Seizure frequency in treatment period = total number of partial seizures in maintenance treatment phase \* 28 divided by total number of days in maintenance treatment phase.

SECONDARY outcome

Timeframe: Baseline, Week 16 (Final Visit )

Population: FAS. A subscale was classified as missing if any of the questions used in the calculation were missing. Abbreviations: BL = Baseline, SOB = short of breath.

MOS-S: subject reported measure with 12 items that assess key constructs of sleep over the past week. Scoring based on 7 subscales: sleep disturbance, snoring, awakened short of breath or with headache, sleep adequacy, and somnolence (range:0-100); sleep quantity (range:0-24), and optimal sleep (yes:1, no:0). Six(6) and 9 item index measures of sleep disturbance were constructed to provide composite scores. Scores are transformed (actual raw score minus lowest possible score divided by possible raw score range \* 100); total score range: 0 to 100; higher score = greater intensity of attribute.

MOS: subject rated questionnaire to assess sleep quality and quantity. Optimal sleep subscale is derived from Sleep Quantity average hours of sleep each night during the past week. Number of subjects with response: YES (Optimal) if sleep quantity was 7 or 8 hours per night, or response = NO (Non-Optimal) if sleep quantity was less than (\<) 7 hours per night. Number of participants with shift in response categories from Baseline to Final Visit.
