Results in Dravet syndrome

Callie, living life with Dravet syndrome

FINTEPLA offers profound
seizure reduction

In the medical community, anything equal to or greater than 75% reduction in monthly seizures is considered a profound result.

In a clinical trial for Dravet syndrome, FINTEPLA reached this incredible achievement.

In a 14-week clinical study, FINTEPLA reduced monthly seizures by 79%This is compared with only 16% for patients taking a placebo

Patients took FINTEPLA (0.7 mg/kg/day) or placebo on top of their current antiseizure treatment plans during the study. Results may vary.

FINTEPLA is available only through the FINTEPLA Risk Evaluation and Mitigation Strategy (REMS), which requires monitoring for potential side effects, such as problems with the heart valves or high blood pressure in the arteries of the lungs. The FINTEPLA REMS was created with your loved one’s safety in mind. It requires that your loved one have regular heart checkups (echocardiograms) to help manage potential safety concerns.
Please see Important Safety Information.

21 days in a row seizure free

In a clinical study, 50% of patients taking FINTEPLA (0.7 mg/kg/day) had a seizure-free streak lasting at least 21 days. This is compared with 8 days for patients taking placebo.

About the Dravet syndrome clinical study

Safety and effectiveness of FINTEPLA were evaluated in 2 clinical studies of patients with Dravet syndrome aged 2 years and older. Study 1 had 117 patients and Study 2 had 85 patients.

Study 1 compared improvement in monthly seizure frequency of 2 different doses of FINTEPLA versus placebo over a 14-week treatment period.

Before joining FINTEPLA Study 1, patients had:

  • Uncontrolled seizures: 6 or more convulsive seizures over the course of 6 weeks
  • A current treatment plan for seizures: 1 to 4 antiseizure medicines or treatments, including use of a vagal nerve stimulator or a ketogenic diet

In the study, patients were randomly placed into 1 of 3 groups:

  • Patients taking 0.2 mg/kg/day of FINTEPLA (n=38)
  • Patients taking 0.7 mg/kg/day of FINTEPLA (n=40)
  • Patients taking placebo (n=39)

All patients added either FINTEPLA or placebo to their existing treatment plans.

As Austen’s seizures started to decrease, we started to hear more laughter, not just from her but from all of our kids.

Long-term results

From the original clinical study

94% of patients continued with FINTEPLA and participated in a long-term, open-label extension study*

Throughout this 36-month, long-term, open-label extension study, most patients maintained the seizure reduction they experienced in the clinical studies.

In this open-label extension study:

64% of patients experienced at least 50% seizure reduction
41% of patients experienced at least 75% seizure reduction

Patients added FINTEPLA (0.7 mg/kg/day) to their current antiseizure treatment plans. Since this was an open-label, flexible-dose study, no conclusions of efficacy or safety should be made based on these results. Results may vary. An open-label study means patients knew they were being treated with FINTEPLA and not a placebo.

  • FINTEPLA is a prescription medicine used to treat seizures associated with Dravet syndrome and Lennox-Gastaut syndrome in patients 2 years of age and older.
  • It is not known if FINTEPLA is safe and effective in children less than 2 years of age.

Important Safety Information

FINTEPLA can cause serious side effects, including:

  1. 1.Problems with the valves in the heart (valvular heart disease) and high blood pressure in the arteries of the lungs (pulmonary arterial hypertension) have been associated with fenfluramine, the active ingredient in FINTEPLA. Your healthcare provider will do a test called an echocardiogram to check your heart and to evaluate for high blood pressure in the arteries of the lungs before you start taking FINTEPLA, again every 6 months during treatment, and one time 3 to 6 months after you take your last dose of FINTEPLA.

    Call your healthcare provider right away if you develop any of these signs and symptoms of heart or lung problems during treatment with FINTEPLA:

    • shortness of breath
    • tiredness or weakness, especially with increased activity
    • lightheadedness or fainting
    • swollen ankles or feet
    • chest pain
    • sensations of a rapid, fluttering heartbeat (palpitations)
    • irregular pulse
    • bluish color of your lips and skin (cyanosis)

    Because of the risk of heart valve problems (valvular heart disease) and high blood pressure in arteries of lungs (pulmonary arterial hypertension), FINTEPLA is only available through a restricted program called the FINTEPLA Risk Evaluation and Mitigation Strategy (REMS) Program. Before you or your child receives FINTEPLA, your healthcare provider or pharmacist will make sure you understand how to take FINTEPLA safely. If you have any questions about FINTEPLA, ask your healthcare provider, visit, or call 1-877-964-3649.

  2. 2. Decreased appetite and decreased weight. Decreased appetite and decreased weight are both serious and common side effects of FINTEPLA in people with Dravet syndrome (DS) or Lennox-Gastaut syndrome (LGS).

    • Your weight should be checked regularly during your treatment with FINTEPLA.
    • Your healthcare provider may need to make changes to your FINTEPLA dose if your weight decreases. In some cases, FINTEPLA may need to be stopped.
  3. 3. Sleepiness, sedation, and lack of energy (lethargy). These are both serious and common side effects of FINTEPLA in people with Dravet syndrome (DS) or Lennox-Gastaut syndrome (LGS). Taking FINTEPLA with central nervous system (CNS) depressants, including alcohol, may increase sleepiness. Do not drive, operate heavy machinery, or do other dangerous activities until you know how FINTEPLA affects you.

  4. 4. Like all other antiepileptic drugs, FINTEPLA may cause suicidal thoughts or actions in a very small number of people (about 1 in 500).

    Call your healthcare provider right away if you have any of these symptoms, especially if they are new, worse, or worry you:

    • thoughts about suicide or dying
    • trouble sleeping (insomnia)
    • attempts to commit suicide
    • new or worse irritability
    • new or worse depression
    • acting aggressive, being angry or violent
    • new or worse anxiety
    • acting on dangerous impulses
    • feeling agitated or restless
    • an extreme increase in activity and talking (mania)
    • panic attacks
    • other unusual changes in behavior or mood

    How can I watch for early symptoms of suicidal thoughts and actions?

    • Pay attention to any changes, especially sudden changes, in mood, behaviors, thoughts, or feelings.
    • Keep all follow-up visits with your healthcare provider as scheduled.

    Suicidal thoughts or actions can be caused by things other than medicines. If you have suicidal thoughts or actions, your healthcare provider may check for other causes.

  5. 5. Do not stop taking FINTEPLA without first talking to your healthcare provider. Stopping a seizure medicine such as FINTEPLA can suddenly cause you to have seizures more often or seizures that do not stop (status epilepticus).

    Call your healthcare provider between visits as needed, especially if you are worried about symptoms.

    Do not take FINTEPLA if you:

    • are allergic to fenfluramine or any of the ingredients in FINTEPLA. See below for a complete list of ingredients in FINTEPLA.
    • are taking or have stopped taking medicines called monoamine oxidase inhibitors (MAOIs) in the last 14 days. This may cause a serious or life-threatening problem called serotonin syndrome. If you are not sure whether or not you are taking one of these medicines, contact your healthcare provider.

    Before taking FINTEPLA, tell your healthcare provider about all of your medical conditions, including if you:

    • have heart problems
    • have or have had weight loss

      • If you become pregnant while taking FINTEPLA, talk to your healthcare provider about registering with the North American Antiepileptic Drug Pregnancy Registry. You can enroll in this registry by calling 1-888-233-2334 or go to The purpose of this registry is to collect information about the safety of antiepileptic drugs during pregnancy.
    • are breastfeeding or plan to breastfeed. It is not known if FINTEPLA passes into your breast milk. Talk to your healthcare provider about the best way to feed your baby while taking FINTEPLA.

    Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements.
