Once-A-Day Pregabalin For Partial Seizures

Seizures were recorded and documented in a daily Seizure Diary by the participants, family member, caregiver, or legal guardian. Simple partial seizures without a visible motor component (ie, lacking visible movements during the seizure) were not counted toward eligibility, or in the primary or secondary efficacy analyses. Participants who had a ≥50% reduction in the 28-day partial seizure rate from baseline were defined as a responder, otherwise they were default as a non-responder.

Simple partial seizures without a visible motor component (ie, lacking visible movements during the seizure) were not counted toward eligibility, or in the primary or secondary efficacy analyses. Natural logarithm of the 28-day seizure rate was reported in this outcome measure.

HADS: participant rated questionnaire with 2 subscales. HADS-A assesses state of generalized anxiety (anxious mood, restlessness, anxious thoughts, panic attacks); HADS-D assesses state of lost interest and diminished pleasure response (lowering of hedonic tone). Each subscale comprised of 7 items with range 0 (no presence of anxiety or depression) to 3 (severe feeling of anxiety or depression). Total score 0 to 21 for each subscale; higher score indicates greater severity of anxiety and depression symptoms.

Participant-rated 12-item questionnaire to assess key constructs of sleep over the past week. 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). 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.

Optimal sleep was considered between 7 to 8 hours of average sleep per night inclusive, while average sleep less than or greater than the 7 to 8 hour of average sleep per night was non-optimal.

The BSW consisted of 3 single-item measures designed to capture the participant's perception of the effect of treatment in terms of the relative benefit, their satisfaction, and their intention or willingness to continue on therapy. The BSW was read aloud to the participant by the investigator or designated center personnel and then was given to the participant to complete independently.

Physical examinations included general appearance (including hight at baseline), vital sign (sitting heart rate and sitting blood pressure), weight, skin (examination for the presence of rash), HEENT (examinatin of head, eyes, ears, nose and throat), chest ausculation of lung fields), cardiovascular (ausculatin of heart sounds (S1 and S2) and for the presence of murmurs, gallops, or rubs), gastrointestinal (abdominal rigidity and tenderness), an extremities (e.g. edema). Clinically significant physical examination abnormalities were considered as adverse events based on investigator's discretion.

Neurological examinations included level of consciousness, mental status, cranial nerve assessment, muscle strength, reflexes, pin prick and vibratory sensation (the latter using a 128-Hz tuning fork), coordination and gait.

C-CASA is described as a standardized suicidal rating system. The C-CASA has eight categories (4 suicidal events: completed suicide, suicide attempt, preparatory act toward imminent suicidal behavior (PAISB), and suicidal ideation; 2 nonsuicidal events: self-injurious behavior, no suicidal intent (SIB-NSI) and other no deliberate self-harm, and 2 indeterminate or potentially suicidal events: self-injurious behavior, suicidal intent unknown and not enough information) that distinguish suicidal events from nonsuicidal events and indeterminate or potentially suicidal events.

The original ECG was reviewed by the investigator and kept on site as part of source documentation. A central ECG reader was also used for this study. QT interval corrected using the Fridericia formula (QTcF) and QT interval corrected using the Bazett's formula (QTcB) were calculated.

The original ECG was reviewed by the investigator and kept on site as part of source documentation. A central ECG reader was also used for this study. 25/50% represents ≥25% or ≥50% increase over baseline respectively, based on cut points. Cut points are 100 ms for QRS and 200 ms for PR.

Laboratory samples in hematology, chemistry, and urinalysis were analyzed by a cental laboratory. Any laboratory value that was identified as clinically significant was reported as an AE. LLN: Lower limit of normal, ULN: Uper limit of normal, RBC: Red Blood Cell, WBC: White Blood Cell, AST: Aspartate Aminotransferase, ALT: Alanine Aminotransferase, BUN: Blood Urea Nitrogen
