Hypersensitivity to brivaracetam or any of the inactive ingredients in BRIVIACT (bronchospasm and angioedema have occurred)

The following serious adverse reactions are described elsewhere in labeling:

There is limited clinical experience with BRIVIACT overdose in humans. Somnolence and dizziness were reported in a patient taking a single dose of 1400 mg (14 times the highest recommended single dose) of BRIVIACT. The following adverse reactions were reported with BRIVIACT overdose: vertigo, balance disorder, fatigue, nausea, diplopia, anxiety, and bradycardia. In general, the adverse reactions associated with BRIVIACT overdose were consistent with the known adverse reactions.

There is no specific antidote for overdose with BRIVIACT. In the event of overdose, standard medical practice for the management of any overdose should be used. An adequate airway, oxygenation, and ventilation should be ensured; monitoring of cardiac rate and rhythm and vital signs is recommended. A certified poison control center should be contacted for updated information on the management of overdose with BRIVIACT. There are no data on the removal of brivaracetam using hemodialysis, but because less than 10% of brivaracetam is excreted in urine, hemodialysis is not expected to enhance BRIVIACT clearance.

The chemical name of BRIVIACT (brivaracetam) is (2S)-2-[(4R)-2-oxo-4-propyltetrahydro-1

Brivaracetam is a white to off-white crystalline powder. It is very soluble in water, buffer (pH 1.2, 4.5, and 7.4), ethanol, methanol, and glacial acetic acid. It is freely soluble in acetonitrile and acetone and soluble in toluene. It is very slightly soluble in n-hexane.

Tablets

BRIVIACT tablets are for oral administration and contain the following inactive ingredients: croscarmellose sodium, lactose monohydrate, betadex (β-cyclodextrin), anhydrous lactose, magnesium stearate, and film coating agents specified below:

10 mg tablets: polyvinyl alcohol, talc, polyethylene glycol 3350, titanium dioxide

Oral Solution

BRIVIACT oral solution contains 10 mg of brivaracetam per mL. The inactive ingredients are sodium citrate, anhydrous citric acid, methylparaben, sodium carboxymethylcellulose, sucralose, sorbitol solution, glycerin, raspberry flavor, and purified water.

Injection

BRIVIACT injection is a clear, colorless liquid provided as a sterile, preservative-free solution. BRIVIACT injection contains 10 mg brivaracetam per mL for intravenous administration. One vial contains 50 mg of brivaracetam drug substance. It contains the following inactive ingredients: sodium acetate, trihydrate (1.64 mg/mL), glacial acetic acid (for pH adjustment to 5.5), sodium chloride (9.00 mg/mL), and water for injection.

The effectiveness of BRIVIACT in partial-onset seizures with or without secondary generalization was established in 3 fixed-dose, randomized, double-blind, placebo-controlled, multicenter studies (Studies 1, 2, and 3), which included 1550 patients. Patients enrolled had partial-onset seizures that were not adequately controlled with 1 to 2 concomitant antiepileptic drugs (AEDs). In each of these studies, 72% to 86% of patients were taking 2 or more concomitant AEDs with or without vagal nerve stimulation. The median baseline seizure frequency across the 3 studies was 9 seizures per 28 days. Patients had a mean duration of epilepsy of approximately 23 years.

All trials had an 8-week baseline period, during which patients were required to have at least 8 partial-onset seizures. The baseline period was followed by a 12-week treatment period. There was no titration period in these studies. Study 1 compared doses of BRIVIACT 50 mg/day and 100 mg/day with placebo. Study 2 compared a dose of BRIVIACT 50 mg/day with placebo. Study 3 compared doses of BRIVIACT 100 mg/day and 200 mg/day with placebo. BRIVIACT was administered in equally divided twice daily doses. Upon termination of BRIVIACT treatment, patients were down-titrated over a 1-, 2-, and 4-week duration for patients receiving 25, 50, and 100 mg twice daily BRIVIACT, respectively.

The primary efficacy outcome in Study 1 and Study 2 was the percent reduction in 7-day partial-onset seizure frequency over placebo, while the primary outcome for Study 3 was the percent reduction in 28-day partial-onset seizure frequency over placebo. The criteria for statistical significance for all 3 studies was p<0.05. Table 6 presents the primary efficacy outcome of the percent change in seizure frequency over placebo, based upon each study's protocol-defined 7- and 28-day seizure frequency efficacy outcome.

Figure 1 presents the percentage of patients by category of reduction from baseline in partial-onset seizure frequency per 28 days for all pooled patients in the 3 pivotal studies. Patients in whom the seizure frequency increased are shown at left as "worse." Patients with an improvement in percent reduction from baseline partial-onset seizure frequency are shown in the 4 right-most categories.

Treatment with Levetiracetam

In Studies 1 and 2, which evaluated BRIVIACT dosages of 50 mg and 100 mg daily, approximately 20% of the patients were on concomitant levetiracetam. Although the numbers of patients were limited, BRIVIACT provided no added benefit when it was added to levetiracetam.

Although patients on concomitant levetiracetam were excluded from Study 3, which evaluated 100 and 200 mg daily, approximately 54% of patients in this study had prior exposure to levetiracetam.

Advise the patient to read the FDA-approved patient labeling (Medication Guide). The Medication Guide accompanies the product and can also be accessed on www.briviact.com or by calling 1-844-599-2273.

Suicidal Behavior and Ideation

Counsel patients, their caregivers, and/or families that antiepileptic drugs, including BRIVIACT, may increase the risk of suicidal thoughts and behavior, and advise patients to be alert for the emergence or worsening of symptoms of depression; unusual changes in mood or behavior; or suicidal thoughts, behavior, or thoughts about self-harm. Advise patients, their caregivers, and/or families to report behaviors of concern immediately to a healthcare provider

Neurological Adverse Reactions

Counsel patients that BRIVIACT causes somnolence, fatigue, dizziness, and gait disturbance. These adverse reactions, if observed, are more likely to occur early in treatment but can occur at any time. Advise patients not to drive or operate machinery until they have gained sufficient experience on BRIVIACT to gauge whether it adversely affects their ability to drive or operate machinery

Psychiatric Adverse Reactions

Advise patients that BRIVIACT causes changes in behavior (e.g., aggression, agitation, anger, anxiety, and irritability) and psychotic symptoms. Instruct patients to report these symptoms immediately to their healthcare provider

Hypersensitivity: Bronchospasm and Angioedema

Advise patients that symptoms of hypersensitivity including bronchospasm and angioedema can occur with BRIVIACT. Instruct them to seek immediate medical care should they experience signs and symptoms of hypersensitivity

Serious Dermatologic Reactions

Advise patients of the early signs and symptoms of serious dermatologic adverse reactions and to report any occurrence immediately to a healthcare provider

Withdrawal of Antiepileptic Drugs

Advise patients not to discontinue use of BRIVIACT without consulting with their healthcare provider. BRIVIACT should normally be gradually withdrawn to reduce the potential for increased seizure frequency and status epilepticus

Pregnancy

Advise patients to notify their healthcare provider if they become pregnant or intend to become pregnant during BRIVIACT therapy. Encourage patients to enroll in the North American Antiepileptic Drug Pregnancy Registry if they become pregnant. This registry is collecting information about the safety of antiepileptic drugs during pregnancy

Lactation

Counsel patients that brivaracetam, the active ingredient in BRIVIACT, is present in breast milk. Instruct patients to discuss with their healthcare provider if they are breastfeeding or intend to breastfeed

Dosing Instructions

Counsel patients that BRIVIACT may be taken with or without food. Instruct patients that BRIVIACT tablets should be swallowed whole with liquid and not chewed or crushed

Advise patients that the dosage of BRIVIACT oral solution should be measured using a calibrated measuring device and not a household teaspoon. Instruct patients to discard any unused BRIVIACT oral solution after 5 months of first opening the bottle
