BRUSSELS, Feb. 19, 2016 /PRNewswire/ -- Today UCB announced that the U.S. Food and Drug Administration (FDA) has approved BRIVIACT® (brivaracetam) as adjunctive therapy (a therapy used together with primary treatment) in the treatment of partial-onset seizures in patients 16 years of age and older with epilepsy. The Drug Enforcement Administration is anticipated to classify BRIVIACT® according to the drug scheduling process within the next 90 days, after which time BRIVIACT® will become commercially available in the U.S.1
"The FDA's approval of BRIVIACT® is significant, because uncontrolled seizures can have serious, long-term effects, and approximately 30% of epilepsy patients remain uncontrolled on currently available treatments," said Dr. Pavel Klein, MD, Director, Mid-Atlantic Epilepsy and Sleep Center, Bethesda, Maryland.
"We are excited to introduce BRIVIACT® as a new therapeutic option that may make a difference in the lives of people with epilepsy in the U.S.," said Jeff Wren, Head of Neurology and Executive Vice President at UCB. "This approval is the culmination of more than eight years of clinical trials involving more than 2,400 adult patients with partial-onset seizures. The development of BRIVIACT® builds upon our longstanding heritage in developing meaningful treatment solutions for people living with epilepsy."
The approved indication is based on data from three pivotal Phase 3 studies (Studies N01252, N01253 and N01358), in which BRIVIACT® demonstrated efficacy over placebo in reducing partial-onset seizure frequency during the treatment period.1
The most common adverse reactions occurring at a frequency of at least 5% in patients treated with BRIVIACT doses of at least 50 mg/day and greater than placebo were somnolence and sedation, dizziness, fatigue, and nausea and vomiting symptoms. The discontinuation rate due to adverse events was 5%, 8%, and 7% for patients randomized to receive BRIVIACT® at the recommended doses of 50 mg, 100 mg, and 200 mg/day, respectively, compared to 4% in patients randomized to receive placebo.1
In January 2016, the European Commission granted the marketing authorization for BRIVIACT® as an adjunctive therapy in the treatment of partial-onset seizures with or without secondary generalization in adult and adolescent patients from 16 years of age with epilepsy. In the EU, BRIVIACT® is already available to patients in the UK and Germany. UCB has submitted additional regulatory applications for brivaracetam in other countries including Australia, Brazil, Canada, Russia, Switzerland and Turkey.
BRIVIACT® is a new molecular entity that was rationally designed and developed by UCB. Brivaracetam displays a high and selective affinity for synaptic vesicle protein 2A (SV2A) in the brain, which may contribute to the anticonvulsant effect. However, the precise mechanism of action by which BRIVIACT® exerts its anticonvulsant activity is not known. BRIVIACT® will be available in three formulations (film-coated tablets, oral solution, and injection).1,4
IMPORTANT SAFETY INFORMATION
Warnings and Precautions
- Suicidal Behavior and Ideation: Antiepileptic drugs, including BRIVIACT, increase the risk of suicidal behavior and ideation. Monitor patients taking BRIVIACT for the emergence or worsening of depression; unusual changes in mood or behavior; or suicidal thoughts, behavior, or self-harm. Advise patients, their caregivers, and/or families to be alert for these behavioral changes and report them immediately to a healthcare provider.
- Neurological Adverse Reactions: BRIVIACT causes somnolence, fatigue, dizziness, and disturbance in coordination. Somnolence and fatigue-related adverse reactions were reported in 25% of patients taking at least 50 mg per day of BRIVIACT compared to 14% of patients taking placebo. Dizziness and disturbance in gait and coordination were reported in 16% of patients taking at least 50 mg per day of BRIVIACT compared to 10% of patients taking placebo. The risk is greatest early in treatment but can occur at any time. Monitor patients for these signs and symptoms and advise them not to drive or operate machinery until they have gained sufficient experience on BRIVIACT.
- Psychiatric Adverse Reactions: BRIVIACT causes psychiatric adverse reactions, including non-psychotic and psychotic symptoms. These events were reported in approximately 13% of patients taking at least 50 mg per day of BRIVIACT compared to 8% of patients taking placebo. A total of 1.7% of adult patients taking BRIVIACT discontinued treatment due to psychiatric reactions compared to 1.3% of patients taking placebo. Advise patients to report these symptoms immediately to a healthcare provider.
- Hypersensitivity: BRIVIACT can cause hypersensitivity reactions. Bronchospasm and angioedema have been reported. Discontinue BRIVIACT if a patient develops a hypersensitivity reaction after treatment. BRIVIACT is contraindicated in patients with a prior hypersensitivity reaction to brivaracetam or any of the inactive ingredients.
- Withdrawal of Antiepileptic Drugs: As with all antiepileptic drugs, BRIVIACT should generally be withdrawn gradually because of the risk of increased seizure frequency and status epilepticus.
The most common adverse reactions (at least 5% for BRIVIACT and at least 2% more frequently than placebo) are somnolence and sedation, dizziness, fatigue, and nausea and vomiting symptoms.

Epilepsy is a chronic neurological disorder affecting approximately 65 million people worldwide and more than 2 million people in the U.S. It is the fourth most common neurological disorder in the U.S. Although epilepsy may be linked to factors such as health conditions, race and age, it can develop in anyone at any age. Approximately one in 26 people will develop epilepsy in their lifetime.
There are many different types of epilepsy but the main characteristic of the condition is recurrent seizures. Seizures are classified by the pattern of onset—partial seizures start in one part of the brain and generalized seizures are characterized by widespread involvement of the whole brain.
Epilepsy is considered to be a disease of the brain defined by any of the following conditions: (1) at least two unprovoked (or reflex) seizures occurring >24 hours apart; (2) one unprovoked (or reflex) seizure and a probability of further seizures similar to the general recurrence risk (at least 60%) after two unprovoked seizures, occurring over the next 10 years; (3) diagnosis of an epilepsy syndrome.
