PBAC outcome
7.1 The PBAC recommended the listing of perampanel for the treatment of primary generalised tonic-clonic (PGTC) seizures in patients with idiopathic generalised epilepsy (IGE), on the basis of a mixed comparison against placebo in refractory patients who have failed to respond adequately to other anti-epileptic drugs (AED); and against other AEDs (valproate, lamotrigine, levetiracetam and topiramate) for refractory patients in whom perampanel will …PSD · Jul 2017
7.2 The PBAC noted the comments in the sponsor hearing and clinician statement and agreed that there was a clinical need for an additional treatment option for patients with PGTC seizures.PSD · Jul 2017
Economic analysis
6.27 The re-submission presented two economic evaluations:  A cost-utility analysis of perampanel (plus standard care) vs. placebo (plus standard care). This approach was consistent with the clinical claim of superiority of perampanel compared with placebo; and  A cost-minimisation analysis of perampanel (plus standard care) vs. other AEDs (plus standard care).PSD · Jul 2017
6.28 The re-submission presented a modelled economic evaluation for perampanel compared with placebo. The model was the same as the one presented in the previous submission, except that the re-submission used an alternative source for health state utilities, and updated cost and mortality components to the most current estimates. A small change was also made to the transition probabilities from the ‘≤50% response’ transition state.PSD · Jul 2017
Clinical claim
6.21 The re-submission described perampanel as superior in terms of comparative effectiveness and inferior in terms of comparative safety to placebo. This is unchanged from the previous submission.PSD · Jul 2017
6.22 The re-submission described perampanel as non-inferior in terms of comparative effectiveness and non-inferior in terms of comparative safety, to either lamotrigine or levetiracetam.PSD · Jul 2017
Consumer comments
6.2 The PBAC noted and welcomed the input from several organisations (3) via the Consumer Comments facility on the PBS website. The comments described the need for a variety of treatments to be available to patients with epilepsy.PSD · Jul 2016
Financial management – risk sharing
6.63 Perampanel is currently PBS listed for partial – onset (or focal) epilepsy and a price- volume based risk-share arrangement exists in conjunction with UCB Biosciences (lacosamide – Vimpat). This is encompassed within a Commonwealth Deed which is intended to expire on 1st April 2020. The sponsor is willing to undertake a separate price-volume, risk-share arrangement for IGE-PGTC.PSD · Jul 2017

Cost-effectiveness

ICER not stated in the public document. The submission included a cost-utility analysis (vs. placebo) and cost-minimisation analysis (vs. other AEDs), but no numeric ICER is printed in this PSD.

ICER uncertainEconomic model disputed

Decision context

PopulationAdults and adolescents aged 12 years or older with Idiopathic Generalised Epilepsy with Primary Generalised Tonic-Clonic seizures who have failed to be controlled satisfactorily by at least two anti-epileptic drugs and require treatment in combination with at least one PBS subsidised anti-epileptic drug.
