Fintepla (fenfluramine) is indicated for the treatment of seizures associated with Dravet syndrome as an add-on therapy to other antiepileptic medicines for patients 2 years of age and older.1

Is Fintepla the next step for your
patients with Dravet syndrome?

Launch of Fintepla in Europe

On the 11th February 2021, a live interactive session was streamed to healthcare professionals in Europe, announcing the launch of Fintepla. The meeting included expert presentations from Prof. Lieven Lagae, Prof. Rima Nabbout and Prof. Julia Jacobs and the content is available on-demand now.

“My personal view is that we should start treating patients quite early in the disease course and we should consider Fintepla as one of the first add-on therapy for those patients.”

Prof. Sameer Zuberi

“Any new option for improving seizure frequency and improving their child's quality of life and their family's quality of life, will be regarded with great enthusiasm and positivity by families and family organisations."

Fintepla demonstrated significant convulsive seizure frequency reduction in patients aged 2-18 years with Dravet syndrome2

When added to an existing antiepileptic drug (AED) regimen (without concomitant stiripentol) Fintepla 0.7mg/kg/day showed a 62.3% greater reduction in mean monthly convulsive seizure frequency than with placebo (primary endpoint) (P<0.0001)

In a 14-week multicentre, randomised, double-blind, parallel group, placebo-controlled study with add-on Fintepla 0.7mg/kg/day (Study 1):2


of patients experienced a ≥50% reduction in mean monthly convulsive seizure frequency (key secondary endpoint)


of patients experienced a ≥75% reduction in mean monthly convulsive seizure frequency (secondary endpoint)


of patients achieved near seizure freedom* (post-hoc analysis)

*Defined as 0 or 1 convulsive seizure during the 14-week treatment period

In a phase 3, randomised, double-blind, placebo-controlled study (Study 2), Fintepla 0.4mg/kg/day showed a greater reduction in mean monthly convulsive seizure frequency than those receiving placebo, when added to an antiepileptic drug (AED) regimen containing stiripentol (primary endpoint)3

Fintepla 0.4mg/kg/day reduced convulsive seizure frequency by ≥50% in 54% of patients when added to an AED regimen containing stiripentol (key secondary endpoint)3

In an open-label extension study Fintepla demonstrated consistent and sustained control in convulsive seizures up to 36 months in patients with Dravet syndrome4


Patients experienced a median reduction in monthly convulsive seizure frequency of 64.5% over the entire treatment period (median treatment duration of 631 days)4
