Notice bibliographique
Résumé
OBJECTIVE: To report the interim results of the PERPRISE study (Study 509; NCT04202159), which is evaluating perampanel as the only adjunctive anti-seizure medication (ASM) in adults with focal to bilateral tonic-clonic seizures (FBTCS) or primary generalized tonic-clonic seizures (GTCS). METHODS: PERPRISE is an ongoing 12-month multicenter, prospective, observational, non-interventional study of perampanel in a real-world setting in Germany. Patients are aged ≥18 years with FBTCS or GTCS due to focal or idiopathic generalized epilepsy. Perampanel, as an adjunctive therapy to ASM monotherapy ('add-on therapy') or as a substitute for one ASM in dual therapy ('substitution therapy'), is prescribed in line with its SmPC. The Interim Analysis Set comprises the first 100 patients who received ≥1 dose of perampanel and attended or discontinued prior to the ~6-month visit. Interim endpoints include retention rate, measures of effects on seizure frequency, and treatment-emergent adverse events (TEAEs). RESULTS: One hundred patients were included in the Interim Analysis Set (add-on, n = 43 [43.0%]; substitution, n = 55 [55.0%]; unknown, n = 2). The 6-month retention rate was 78.0% (add-on, 83.7%; substitution, 72.7%). For the overall population with GTCS and/or FBTCS, seizure-freedom rate at 6 months was 58.8% (add-on, 72.2%; substitution, 47.9%) and 50% responder rate at 6 months was 82.6% (add-on, 89.2%; substitution, 76.6%). Retention rates and seizure outcomes were better with perampanel as an early-line treatment than as a late-line treatment. TEAEs were reported by 48 patients (48.0%), most commonly dizziness (n = 9), fatigue (n = 7), and irritability (n = 7). Sixteen patients (16.0%) withdrew from perampanel treatment due to TEAEs. SIGNIFICANCE: The interim analysis of PERPRISE offers insight into the real-world use of perampanel in Germany, including for the first time, clinical practice data from patients with GTCS and switching ASMs within a dual therapy. Further data from PERPRISE will be of value to inform clinical decision-making in this patient cohort. PLAIN LANGUAGE SUMMARY: Patients with epilepsy often take more than one medication for seizure control. This 12month study looked at patients in Germany receiving perampanel as only add-on medication. The interim analysis shows, that at 6 months, over 70% of the 100 patients continued to use perampanel; 59% experienced no seizures during treatment with perampanel, and in 83%, seizure frequency was reduced by half. Side effects occurred in 48% of patients (most commonly dizziness, fatigue, and irritability) and caused 16% to withdraw from the study. Overall, perampanel was a suitable as only add-on medication for patients with epilepsy.

Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
