OBJECTIVE: Assess cognitive effects of adjunctive perampanel in adolescents.
METHODS: In this double-blind study (ClinicalTrials.gov identifier: NCT01161524), patients aged 12 to <18 years with partial-onset seizures despite receiving 1-3 antiepileptic drugs were randomized (2:1) to perampanel or placebo. Perampanel was increased weekly in 2-mg increments to 8-12 mg/day (6-week titration; 13-week maintenance). Changes in neuropsychological outcomes were assessed at end of maintenance: Cognitive Drug Research (CDR) System Global Cognition Score (primary end point), five CDR System domain T-scores (secondary end points), letter fluency, category fluency, and Lafayette Grooved Pegboard Test (LGPT).
RESULTS: One hundred thirty-three patients were randomized. In the full analysis set, there were no differences of perampanel (n = 79) vs. placebo (n = 44) in CDR System Global Cognition Score (least squares mean change, -0.6 vs. 1.6; p = 0.145), Quality of Working Memory (1.1 vs. 2.0; p = 0.579), or Power of Attention (-6.9 vs. -2.7; p = 0.219). There were small differences with perampanel vs. placebo in other CDR System domains: improvements in Quality of Episodic Memory (3.0 vs. -1.2; p = 0.012), and worsening in Continuity of Attention (-3.3 vs. 1.6; p = 0.013) and Speed of Memory (0.3 vs. 7.0; p = 0.032). Letter fluency, category fluency, and LGPT were not significantly different between groups. The most frequent adverse events with perampanel were dizziness (30.6%) and somnolence (15.3%).
SIGNIFICANCE: Perampanel did not differ from placebo in the global cognitive score, two of five subdomains, and four other cognitive measures. Perampanel was worse on two and better on one subdomain.
