Abstract
Perampanel, a novel, noncompetitive, selective AMPA-receptor antagonist demonstrated evidence of efficacy in reducing motor symptoms in animal models of Parkinson's disease (PD). We assessed the safety and efficacy of perampanel for treatment of "wearing off" motor fluctuations in patients with PD. Patients (N = 263) were randomly assigned to once-daily add-on 0.5, 1, or 2 mg of perampanel or placebo. The primary objective was to determine whether there was a dose-response relationship for efficacy among the 3 perampanel doses and placebo. The primary efficacy endpoint for each treatment was measured as the least-squares (LS) mean change from baseline to week 12 in percent "off' time reduction during the waking day, as recorded by patient diaries. The primary efficacy analysis was a 1-sided Williams test for dose-response trend at the 0.025 level of significance. At week 12, dose-response trends, as determined by the Williams test, were not statistically significant for LS mean reduction in percent "off" time during the waking day (P = 0.061, with significance defined as P ≤ 0.025). The 2 higher perampanel doses (ITT population; n = 258) produced non-significant reductions from baseline to week 12 in percent "off" time during the waking day versus placebo (7.59%, P = 0.421 [1 mg], 8.60%, P = 0.257 [2 mg] versus 5.05% [placebo]; significance for pairwise comparisons defined as P ≤ 0.05). There were no significant changes in dyskinesia or cognitive function in any perampanel group versus placebo. Adverse events were similar across treatment groups. Perampanel treatment was well tolerated and safe, but failed to achieve statistical significance in primary and secondary endpoints.

Patients (N = 263) were randomly assigned to once-daily add-on 0.5, 1, or 2 mg of perampanel or placebo. The primary objective was to determine whether there was a dose-response relationship for efficacy among the 3 perampanel doses and placebo. The primary efficacy endpoint for each treatment was measured as the least-squares (LS) mean change from baseline to week 12 in percent "off' time reduction during the waking day, as recorded by patient diaries. The primary efficacy analysis was a 1-sided Williams test for dose-response trend at the 0.025 level of significance. At week 12, dose-response trends, as determined by the Williams test, were not statistically significant for LS mean reduction in percent "off" time during the waking day (P = 0.061, with significance defined as P ≤ 0.025). The 2 higher perampanel doses (ITT population; n = 258) produced non-significant reductions from baseline to week 12 in percent "off" time during the waking day versus placebo (7.59%, P = 0.421 [1 mg], 8.60%, P = 0.257 [2 mg] versus 5.05% [placebo]; significance for pairwise comparisons defined as P ≤ 0.05). There were no significant changes in dyskinesia or cognitive function in any perampanel group versus placebo. Adverse events were similar across treatment groups. Perampanel treatment was well tolerated and safe, but failed to achieve statistical significance in primary and secondary endpoints.</div></front></TEI><affiliations><list><country><li>Allemagne</li><li>Autriche</li><li>Espagne</li><li>France</li><li>Italie</li><li>Royaume-Uni</li><li>République tchèque</li><li>Serbie</li><li>Turquie</li><li>États-Unis</li></country><region><li>Angleterre</li><li>Bohême centrale</li><li>Catalogne</li><li>District de Cologne</li><li>District de Giessen</li><li>District de Kassel</li><li>Grand Londres</li><li>Hesse (Land)</li><li>Latium</li><li>Midi-Pyrénées</li><li>New Jersey</li><li>Rhénanie-du-Nord-Westphalie</li><li>Tyrol (Land)</li><li>Vienne (Autriche)</li></region><settlement><li>Barcelone</li><li>Bonn</li><li>Cassel (Hesse)</li><li>Innsbruck</li><li>Londres</li><li>Marbourg</li><li>Prague</li><li>Rome</li><li>Toulouse</li><li>Vienne (Autriche)</li></settlement><orgName><li>National Hospital for Neurology and Neurosurgery</li><li>Université Toulouse III - Paul Sabatier</li><li>Université de Toulouse</li><li>Université de médecine d'Innsbruck</li></orgName></list><tree><country name="Allemagne"><region name="Hesse (Land)"><name sortKey="Eggert, Karla" sort="Eggert, Karla" uniqKey="Eggert K" first="Karla" last="Eggert">Karla Eggert</name></region><name sortKey="Dodel, Richard" sort="Dodel, Richard" uniqKey="Dodel R" first="Richard" last="Dodel">Richard Dodel</name><name sortKey="Oertel, Wolfgang" sort="Oertel, Wolfgang" uniqKey="Oertel W" first="Wolfgang" last="Oertel">Wolfgang Oertel</name><name sortKey="Trenkwalder, Claudia" sort="Trenkwalder, Claudia" uniqKey="Trenkwalder C" first="Claudia" last="Trenkwalder">Claudia Trenkwalder</name></country><country name="États-Unis"><region name="New Jersey"><name sortKey="Squillacote, David" sort="Squillacote, David" uniqKey="Squillacote D" first="David" last="Squillacote">David Squillacote</name></region></country><country name="Italie"><noRegion><name sortKey="Barone, Paolo" sort="Barone, Paolo" uniqKey="Barone P" first="Paolo" last="Barone">Paolo Barone</name></noRegion><name sortKey="Nappi, Giuseppe" sort="Nappi, Giuseppe" uniqKey="Nappi G" first="Giuseppe" last="Nappi">Giuseppe Nappi</name><name sortKey="Nappi, Giuseppe" sort="Nappi, Giuseppe" uniqKey="Nappi G" first="Giuseppe" last="Nappi">Giuseppe Nappi</name><name sortKey="Onofrj, Marco" sort="Onofrj, Marco" uniqKey="Onofrj M" first="Marco" last="Onofrj">Marco Onofrj</name><name sortKey="Stocchi, Fabrizio" sort="Stocchi, Fabrizio" uniqKey="Stocchi F" first="Fabrizio" last="Stocchi">Fabrizio Stocchi</name></country><country name="Autriche"><region name="Vienne (Autriche)"><name sortKey="Katzenschlager, Regina" sort="Katzenschlager, Regina" uniqKey="Katzenschlager R" first="Regina" last="Katzenschlager">Regina Katzenschlager</name></region><name sortKey="Poewe, Werner" sort="Poewe, Werner" uniqKey="Poewe W" first="Werner" last="Poewe">Werner Poewe</name></country><country name="Turquie"><noRegion><name sortKey="Emre, Murat" sort="Emre, Murat" uniqKey="Emre M" first="Murat" last="Emre">Murat Emre</name></noRegion></country><country name="Royaume-Uni"><region name="Angleterre"><name sortKey="Lees, Andrew J" sort="Lees, Andrew J" uniqKey="Lees A" first="Andrew J." last="Lees">Andrew Lees (neurologue)</name></region></country><country name="France"><noRegion><name sortKey="Rascol, Olivier" sort="Rascol, Olivier" uniqKey="Rascol O" first="Olivier" last="Rascol">Olivier Rascol</name></noRegion><name sortKey="Rascol, Olivier" sort="Rascol, Olivier" uniqKey="Rascol O" first="Olivier" last="Rascol">Olivier Rascol</name></country><country name="Espagne"><region name="Catalogne"><name sortKey="Tolosa, Eduardo" sort="Tolosa, Eduardo" uniqKey="Tolosa E" first="Eduardo" last="Tolosa">Eduardo Tolosa</name></region></country><country name="Serbie"><noRegion><name sortKey="Kostic, Vladimir" sort="Kostic, Vladimir" uniqKey="Kostic V" first="Vladimir" last="Kostic">Vladimir Kostic</name></noRegion><name sortKey="Potic, Jagoda" sort="Potic, Jagoda" uniqKey="Potic J" first="Jagoda" last="Potic">Jagoda Potic</name></country><country name="République tchèque"><region name="Bohême centrale"><name sortKey="Ruzicka, Evzen" sort="Ruzicka, Evzen" uniqKey="Ruzicka E" first="Evzen" last="Ruzicka">Evzen Ruzicka</name></region></country></tree></affiliations></record>Pour manipuler ce document sous Unix (Dilib)
