Introducing ONTOZRY®▼ (cenobamate)

ONTOZRY® is indicated for the adjunctive treatment of focal-onset seizures with or without secondary generalisation in adult patients with epilepsy who have not been adequately controlled, despite treatment with at least 2 anti-epileptic medicinal products1

Why choose ONTOZRY®?

Significant unmet need remains for patients with epilepsy, particularly for those with uncontrolled epilepsy5

In clinical studies of patients with uncontrolled focal seizures, ONTOZRY® significantly reduced seizure frequency compared with placebo7 

    • 56% of patients achieved a ≥50% reduction in seizure frequency with ONTOZRY® 200 mg/day vs 25% of patients with placebo when added to SOC1,7*,† 

Seizure freedom is possible with ONTOZRY® for some drug-resistant patients7 

    • 21% of patients achieved seizure freedom with ONTOZRY® 400 mg/day vs 1% of patients with placebo when added to SOC1,7*,‡ 

ONTOZRY® is generally well tolerated, with a dose-dependent TEAE profile1,7 

    • Most common adverse reactions were somnolence, dizziness, fatigue and headache1,7

Footnotes

*In the randomly assigned population at baseline, median number of previous ASMs taken at any time before the start of the study was 3 (range 2 - 4); these might or might not have been ongoing during the study. 74% (n=322/437) of patients were taking 2–3 concomitant ASMs during the study.7

†During the 12-week maintenance phase of fixed-dose, double-blind treatment, responder rates from baseline were 25% (n=26/102) for the placebo group compared with 56% (n=55/98; OR 3.74 [2.06-6.80], 95% CI; p<0.0001) for the ONTOZRY® 200 mg/day dose group.7

‡Seizure freedom was defined as 100% reduction in seizure frequency. During the 12-week maintenance phase, seizure freedom responder rates from baseline were 1% (n=1/102) for the placebo group, 4% (n=4/102) for the ONTOZRY® 100 mg/day group, 11% (n=11/98; p=0.0022) for the ONTOZRY® 200 mg/day group and 21% (n=20/95; p<0.0001) for the ONTOZRY® 400 mg/day group.7

ASM = anti-seizure medication; CI = confidence interval; OR = odds ratio, SOC = standard of care; TEAE = treatment-emergent adverse event.
