New indication for BRIVIACT® (brivaracetam): UCB's newest antiepileptic drug approved by FDA as monotherapy treatment of partial-onset seizures in adults

ATLANTA and BRUSSELS, Sept. 15, 2017 /PRNewswire/ -- UCB announced today that the U.S. Food and Drug Administration (FDA) has approved a supplemental new drug application (sNDA) for BRIVIACT^® (brivaracetam) CV as monotherapy for partial-onset (focal) seizures (POS) in patients 16 years and older with epilepsy.¹

This is a new indication for BRIVIACT, which is already approved in the U.S. as adjunctive treatment for POS in patients in this age group. As a result, adults and adolescents aged 16 years and older with POS in the U.S. can now be initiated on BRIVIACT as monotherapy or adjunctive therapy.

BRIVIACT is the newest antiepileptic drug (AED) in the 'racetam' class of medicines and demonstrates a high and selective affinity for synaptic vesicle protein 2A (SV2A) in the brain, which may contribute to its anticonvulsant effects. Gradual dose escalation is not required when initiating treatment with BRIVIACT for monotherapy or adjunctive therapy, allowing clinicians to initiate treatment at a therapeutic dose from day one.¹

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.¹ Please see additional BRIVIACT Important Safety Information below. 

"This new monotherapy indication builds on an already strong and compelling clinical profile for BRIVIACT, providing doctors the flexibility to tailor their choice of AED to match individual patient needs and circumstances," explained Dr. Pavel Klein, director of the Mid-Atlantic Epilepsy and Sleep Center. "In helping to progress their journey towards seizure freedom by providing a choice of treatment which can be initiated as monotherapy, at a therapeutic dose, from day one, BRIVIACT provides an additional treatment choice for neurologists and their patients."

UCB submitted a supplemental application for a BRIVIACT monotherapy indication taking into account a recent General Advice Letter, issued by the FDA,² which stated it is acceptable to extrapolate the efficacy and safety of drugs approved as adjunctive therapy for the treatment of POS to their use as monotherapy for the treatment of POS. As a result of the FDA's approach to assessing extrapolated data, UCB was able to support its BRIVIACT monotherapy submission with a wealth of brivaracetam clinical trials data, which involved more than 2,400 adult patients with POS.¹

"We are delighted that, with this new monotherapy indication for BRIVIACT, we can support people with epilepsy to reach their treatment goals. Coming just 18 months after our launch in the U.S., this is evidence of our commitment to increasing the speed at which our therapies are approved and made available to as many patients as possible," explained Jeff Wren, Executive Vice-President, Head of UCB's Neurology Patient Value Unit. "Discovering, validating and improving access to new and innovative solutions to support people living with epilepsy has been, and will continue to be, a core UCB mission. With this BRIVIACT monotherapy indication, we build on our longstanding commitment to help people with seizure disorders at every point of their journey."

About Epilepsy^3,4,5,6

Epilepsy is a chronic neurological disorder of the brain. It is the fourth most common neurological condition worldwide and affects approximately 65 million people. In the U.S., more than 3 million people have epilepsy. Anyone can develop epilepsy; it occurs across all ages, races and genders, and is defined as one or more unprovoked seizures with a risk of further seizures. Around one-third of patients with epilepsy currently live with uncontrolled seizures.

About BRIVIACT^1,7

BRIVIACT (brivaracetam) 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.

In the U.S., BRIVIACT is approved as monotherapy and adjunctive therapy (a therapy used together with primary treatment) for the treatment of partial-onset seizures in patients 16 years of age and older with epilepsy. BRIVIACT is available in three formulations (film-coated tablets, oral solution, and injection).

In the European Union, BRIVIACT is approved as adjunctive therapy in the treatment of partial-onset seizures in patients 16 years of age and older with epilepsy. The European Medicines Agency has different regulatory requirements from FDA for approval of monotherapy indications.

Important Safety Information about BRIVIACT^® in the U.S.¹

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.

Dosing Considerations

• Dose adjustments are recommended for patients with all stages of hepatic impairment.
• When BRIVIACT is co-administered with rifampin, an increase in the BRIVIACT dose is recommended.

Adverse Reactions

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.

BRIVIACT is a Schedule V controlled substance.
