Patients Treated with Eslicarbazepine Acetate Monotherapy Show Quality of Life Improvement (P2.028)

OBJECTIVE: To evaluate changes in health-related quality-of-life (HRQOL) among epilepsy patients who received eslicarbazepine acetate (ESL) monotherapy (1200 mg QD or 1600 mg QD).
BACKGROUND: Patient quality of life is important in treatment decision-making. Information on HRQOL in patients with partial-onset seizures, not being controlled by anti-epileptic drugs, was collected in two randomized, historical-controlled, double-blind clinical trials of ESL monotherapy (093-045/093-046) using the Quality of Life in Epilepsy-31 (QOLIE-31).
DESIGN/METHODS: This analysis examined changes from baseline to week 18 (end of monotherapy period) in QOLIE-31 Total Score and its seven subscales among two groups of patients pooled from the two trials: 1) those who converted to ESL monotherapy over an 8-week taper/conversion period and remained on monotherapy through week 18 (Completers; n=226, 68.1[percnt] of efficacy population), and 2) those who achieved a seizure frequency reduction ≥50[percnt] (Responders; n=134, 40.4[percnt] of efficacy population). Mean changes were tested for being significantly different than zero using paired two-sided t-tests and were also compared to established minimal clinically-important differences (MCIDs).
RESULTS: The QOLIE-31 was completed at both baseline and week 18 by 211 (93.4[percnt]) of 226 Completers and 107 (79.9[percnt]) of 134 Responders. Among Completers and Responders, Total Score significantly improved and exceeded the MCID of 5.19 (mean change=6.72, p p p p <0.05). Lastly, six subscales among Completers and five subscales among Responders showed improvement above their MCIDs.
CONCLUSIONS: In this pooled analysis, patients who converted to ESL monotherapy and/or achieved a seizure frequency reduction ≥50[percnt] experienced significant improvement in HRQOL, with many experiencing clinically-meaningful improvement.
