Abstract
Objective: to evaluate the efficacy and tolerability of perampanel suspension (Fycompa®) in real-world clinical practice among children and adolescents with epilepsy in a cohort of Russian patients.
Material and methods. A retrospective multicenter analysis was conducted of depersonalized data from 80 patients from 27 centres (40 boys, 40 girls) aged between 4–18 years (mean age 8.2 years) with various forms of epilepsy who received perampanel suspension (PER) as adjunctive therapy. Inclusion criteria were a verified diagnosis of epilepsy consistent with the drug's approved indications, and the availability of data on seizure frequency prior to treatment and after 1–3 months of therapy. To assess efficacy after 3–6 months, data were used from patients who continued treatment and had corresponding records. Statistical analysis was performed using descriptive statistical methods. The primary outcome measures were changes in seizure frequency after 1–3 and 3–6 months of therapy, the proportion of responders, the rate of remission, and adverse events (AEs).
Results. After 1–3 months of treatment, the highest efficacy was observed in isolated bilateral tonic-clonic seizures (BTCS; remission – 78.5%, overall response rate – 89.2%) and generalised tonic-clonic seizures (GTCS; remission – 71.4%, overall response rate – 100%). For focal seizures (FS) without progression to BTCS, remission was 38%, and the overall response rate was 71%. In FS progressing to BTCS, remission was recorded in 37.5% of patients, with an overall response rate of 62.5%. In patients with a combination of these seizure types and other types of seizures, a reduction in the frequency of concomitant seizures was also observed. At the 3–6-month stage, an additional response (remission or a ≥50% reduction in seizure frequency) was observed in only a small proportion of patients (for example, additional remission in FS without BTCS was observed in 10.3% of patients). The drug demonstrated reasonably good tolerability: AEs were reported in 16.3% of patients after 1–3 months, and the need for discontinuation was 2.5%.
Conclusion. The PER suspension is well tolerated and effective in children aged 4 years and older with FS, with or without progression to BTCS, and in children aged 7 years and older with GTCS, including patients weighing less than 30 kg. The liquid formulation allows for precise dose titration and is convenient to administer, particularly in patients with dysphagia.
