Trial Outcomes & Findings for Perampanel in Seizure Patients With Primary Glial Brain Tumors (NCT NCT02363933)

NCT ID: NCT02363933

Last Updated: 2018-04-27

Results Overview

The primary objective of this study is to assess the efficacy of perampanel as an adjunctive anti-epileptic drug (AED) in patients with primary glioma presenting refractory partial onset seizure activity. Efficacy will be assessed by the 50% responder rate, defined as the percentage of patients with a ≥50% seizure reduction during the maintenance period compared with the seizure frequency before initiation of perampanel. Seizure frequency during maintenance perampanel will be computed as the ratio of the total number of seizure episodes while receiving perampanel during the maintenance period and the number of days perampanel is administered

Measure
Perampanel + Current Anti-Epileptic Drug
Primary glioma patients will receive perampanel along with their current AED for a total of 20 weeks. Perampanel will be titrated from 2 mg in weeks 1 and 2 and up to 8 mg daily by week 5 if well tolerated by the patient. They will then receive a maintenance dose of 8 mg per day through 16 weeks. After 16 weeks, subjects will be tapered off perampanel over a 4 week period. Perampanel: Perampanel is a highly selective non-competitive alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) type glutamate receptor antagonist that has shown efficacy in a randomized phase III study for refractory partial-onset seizures

PRIMARY outcome

Timeframe: 20 Weeks

Population: Seizure frequency was not systematically gathered at screening. As the 50% responder rate requires an adequate baseline comparison, it is not possible to compute the 50% responder rate.

The primary objective of this study is to assess the efficacy of perampanel as an adjunctive anti-epileptic drug (AED) in patients with primary glioma presenting refractory partial onset seizure activity. Efficacy will be assessed by the 50% responder rate, defined as the percentage of patients with a ≥50% seizure reduction during the maintenance period compared with the seizure frequency before initiation of perampanel. Seizure frequency during maintenance perampanel will be computed as the ratio of the total number of seizure episodes while receiving perampanel during the maintenance period and the number of days perampanel is administered

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: 24 Weeks

Population: All patients treated with perampanel is included in the attributable adverse event rate.

The percentage of patients with unacceptable adverse events that are possibly, probably, or definitely related to perampanel treatment will be calculated. Unacceptable adverse events include all Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 Grade 4 or 5 toxicities that are possibly, probably, or definitely related to perampanel, as well as suicidal ideation (any grade) or suicide attempt (Grade 3-5).
