The following serious adverse reactions are described elsewhere in labeling:
- Suicidal Behavior and Ideation [see WARNINGS AND PRECAUTIONS]
- Neurological Adverse Reactions [see WARNINGS AND PRECAUTIONS]
- Psychiatric Adverse Reactions [see WARNINGS AND PRECAUTIONS]
- Hypersensitivity: Bronchospasm and Angioedema [see WARNINGS AND PRECAUTIONS]
- Withdrawal of Antiepileptic Drugs [see WARNINGS AND PRECAUTIONS]
Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
In all controlled and uncontrolled trials performed in adult epilepsy patients, BRIVIACT was administered as adjunctive therapy to 2437 patients. Of these patients, 1929 were treated for at least 6 months, 1500 for at least 12 months, 1056 for at least 24 months, and 758 for at least 36 months. A total of 1558 patients (1099 patients treated with BRIVIACT and 459 patients treated with placebo) constituted the safety population in the pooled analysis of Phase 3 placebo-controlled studies in patients with partial-onset seizures (Studies 1, 2, and 3) [see Clinical Studies]. The adverse reactions presented in Table 2 are based on this safety population; the median length of treatment in these studies was 12 weeks. Of the patients in those studies, approximately 51% were male, 74% were Caucasian, and the mean age was 38 years.
In the Phase 3 controlled epilepsy studies, adverse events occurred in 68% of patients treated with BRIVIACT and 62% treated with placebo. 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 (16%), dizziness (12%), fatigue (9%), and nausea and vomiting symptoms (5%).
The discontinuation rates due to adverse events were 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.
Table 3 lists adverse reactions for BRIVIACT that occurred at least 2% more frequently for BRIVIACT doses of at least 50 mg/day than placebo.
Table 3: Adverse Reactions in Pooled
Placebo-Controlled Adjunctive Therapy Studies in Adult Patients with
Partial-Onset Seizures (BRIVIACT50 mg/day,100 mg/day,and200 mg/day)
|Nervous system disorders|
|Somnolence and sedation||16||8|
|Cerebellar coordination and balance disturbances*||3||1|
|* Cerebellar coordination and balance disturbances includes ataxia, balance disorder, coordination abnormal, and nystagmus.|
There was no apparent dose-dependent increase in adverse reactions listed in Table 3 with the exceptionof somnolence and sedation.
Pediatric Patients(4 Years To Less Than 16 Years Of Age)
Safety of BRIVIACT was evaluated in two open-label, safety and pharmacokinetic trials in pediatric patients 4 years to less than 16 years of age. Across studies of pediatric patients with partial onset seizures, 149 patients 4 years to less than16 years of age received BRIVIACT oral solution or tablet, of whom 107 received BRIVIACT for at least 12 months. Adverse reactions reported in clinical studies of pediatric patients 4 years to less than16 years of age were generally similar to those seen in adult patients.
BRIVIACT can cause hematologic abnormalities. In the Phase 3 controlled adjunctive epilepsy studies, a total of 1.8% of BRIVIACT-treated patients and 1.1% of placebo-treated patients had at least one clinically significant decreased white blood cell count(<3.0x109/L),and0.3%ofBRIVIACT-treated patientsand0%ofplacebo-treatedpatientshadatleastoneclinically significant decreased neutrophil count (<1.0 x109/L).
Adverse Reactions With BRIVIACT Injection
Adverse reactions with BRIVIACT injection administered to adult patients were generally similar to those observed with BRIVIACT tablets. Other adverse events that occurred in at least 3% of patients who received BRIVIACT injection included dysgeusia, euphoric mood, feeling drunk, and infusion site pain.
Comparison By Sex
There were no significant differences by sex in the incidence of adverse reactions.
Co-administration with rifampin decreases BRIVIACT plasma concentrations likely because of CYP2C19 induction [see CLINICAL PHARMACOLOGY]. Prescribers should increase the BRIVIACT dose by up to 100% (i.e., double the dosage) in patients while receiving concomitant treatment with rifampin [see DOSAGE AND ADMINISTRATION].
Co-administration with carbamazepine may increase exposure to carbamazepine-epoxide, the active metabolite of carbamazepine. Though available data did not reveal any safety concerns, if tolerability issues arise when co-administered, carbamazepine dose reduction should be considered [see CLINICAL PHARMACOLOGY].
Because BRIVIACT can increase plasma concentrations of phenytoin, phenytoin levels should be monitored in patients when concomitant BRIVIACT is added to or discontinued from ongoing phenytoin therapy [see CLINICAL PHARMACOLOGY].
BRIVIACT provided no added therapeutic benefit to levetiracetam when the two drugs were co-administered [see Clinical Studies].
Drug Abuse And Dependence
BRIVIACT contains brivaracetam and is listed as a Schedule V controlled substance.
In a human abuse potential study, single doses of BRIVIACT at therapeutic and supratherapeutic doses were compared to alprazolam (C-IV) (1.5 mg and 3 mg). BRIVIACT at the recommended single dose (50 mg) caused fewer sedative and euphoric effects than alprazolam; however, BRIVIACT at supratherapeutic single doses (200mg and 1000 mg) was similar to alprazolam on other measures of abuse.
There was no evidence of physical dependence potential or a withdrawal syndrome with BRIVIACT in a pooled review of placebo-controlled adjunctive therapy studies [see WARNINGS AND PRECAUTIONS].
Included as part of the PRECAUTIONS section.
Suicidal Behavior And Ideation
Antiepileptic drugs (AEDs), including BRIVIACT, increase the riskof suicidal thoughts or behavior in patients taking these drugs for any indication. Patients treated with any AED for any indication should be monitored for the emergence or worsening of depression, suicidal thoughts or behavior, and/or any unusual changes in mood or behavior.
Pooled analyses of 199 placebo-controlled clinical trials (mono-and adjunctive therapy) of 11 different AEDs showed that patients randomized to one of the AEDs had approximately twice the risk (adjusted Relative Risk 1.8, 95% CI:1.2, 2.7) of suicidal thinking or behavior compared to patients randomized to placebo. In these trials, which had a median treatment duration of 12 weeks, the estimated incidence rate of suicidal behavior or ideation among 27,863 AED-treated patients was 0.43%, compared to 0.24% among 16,029 placebo-treated patients, representing an increase of approximately one case of suicidal thinking or behavior for every 530 patients treated. There were four suicides in drug-treated patients in the trials and none in placebo-treated patients, but the number is too small to allow any conclusion about drug effect on suicide.
The increased risk of suicidal thoughts or behavior with AEDs was observed as early as one week after starting drug treatment with AEDs and persisted for the duration of treatment assessed. Because most trials included in the analysis did not extend beyond 24 weeks, the risk of suicidal thoughts or behavior beyond 24 weeks could not be assessed.
The risk of suicidal thoughts or behavior was generally consistent among drugs in the data analyzed. The finding of increased risk with AEDs of varying mechanisms of action and across a range of indications suggests that the risk applies to all AEDs used for any indication. The risk did not vary substantially by age (5-100 years) in the clinical trials analyzed. Table 2 shows absolute and relative risk by indication for all evaluated AEDs.
Table 2: Risk of Suicidal Thoughts Or Behaviors By Indication
For Antiepileptic Drugs In The Pooled Analysis
|Indication||Placebo Patients with Events Per 1000 Patients||Drug Patients with Events Per 1000 Patients||Relative Risk: Incidence of Events in Drug Patients/Incidence in Placebo Patients||Risk Difference: Additional Drug Patients with Events Per 1000 Patients|
The relative risk for suicidal thoughts or behavior was higher in clinical trials in patients with epilepsy than in clinical trials in patients with psychiatric or other conditions, but the absolute risk differences were similar for the epilepsy and psychiatric indications.
Anyone considering prescribing BRIVIACT or any other AED must balance the risk of suicidal thoughts or behaviors with the risk of untreated illness. Epilepsy and many other illnesses for which AEDs are prescribed are themselves associated with morbidity and mortality and an increased risk of suicidal thoughts and behavior. Should suicidal thoughts and behavior emerge during treatment, consider whether the emergence of these symptoms in any given patient may be related to the illness being treated.
Neurological Adverse Reactions
BRIVIACT causes somnolence, fatigue, dizziness, and disturbance in coordination. Patients should be monitored for these signs and symptoms and advised 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.
Somnolence And Fatigue
BRIVIACT causes dose-dependent increases in somnolence and fatigue-related adverse reactions (fatigue, asthenia, malaise, hypersomnia, sedation, and lethargy) [see ADVERSE REACTIONS]. In the Phase 3 controlled adjunctive epilepsy trials, these events were reported in 25% of patients randomized to receive BRIVIACT at least 50 mg/day (20% at 50 mg/day, 26% at 100 mg/day, and 27% at 200 mg/day) compared to 14% of patients who received placebo. The risk is greatest early in treatment but can occur at any time.
Dizziness And Disturbance In Gait And Coordination
BRIVIACT causes adverse reactions related to dizziness and disturbance in gait and coordination (dizziness, vertigo, balance disorder, ataxia, nystagmus, gait disturbance, and abnormal coordination) [see ADVERSE REACTIONS]. In the Phase 3 controlled adjunctive epilepsy trials, these events were reported in 16% of patients randomized to receive BRIVIACT at least 50 mg/day compared to 10% of patients who received placebo. The risk is greatest early in treatment but can occur at any time.
Psychiatric Adverse Reactions
BRIVIACT causes psychiatric adverse reactions. In the Phase 3 controlled adjunctive epilepsy trials, psychiatric adverse reactions were reported in approximately 13% of patients who received BRIVIACT (at least 50 mg/day) compared to 8% of patients who received placebo. Psychiatric events included both non-psychotic symptoms (irritability, anxiety, nervousness, aggression, belligerence, anger, agitation, restlessness, depression, depressed mood, tearfulness, apathy, altered mood, mood swings, affect lability, psychomotor hyperactivity, abnormal behavior, and adjustment disorder) and psychotic symptoms (psychotic disorder along with hallucination, paranoia, acute psychosis, and psychotic behavior). A total of 1.7% of adult patients treated with BRIVIACT discontinued treatment because of psychiatric reactions compared to 1.3% of patients who received placebo.
Psychiatric adverse reactions were also observed in open-label pediatric trials and were generally similar to those observed in adults [see ADVERSE REACTIONS and Use In Specific Populations].
Hypersensitivity: Bronchospasm And Angioedema
BRIVIACT can cause hypersensitivity reactions. Bronchospasm and angioedema have been reported in patients taking BRIVIACT. If a patient develops hypersensitivity reactions after treatment with BRIVIACT, the drug should be discontinued. BRIVIACT is contraindicated in patients with a prior hypersensitivity reaction to brivaracetam or any of the inactive ingredients [see CONTRAINDICATIONS].
Withdrawal Of Antiepileptic Drugs
As with most antiepileptic drugs, BRIVIACT should generally be withdrawn gradually because of the risk of increased seizure frequency and status epilepticus [see DOSAGE AND ADMINISTRATION and Clinical Studies]. But if withdrawal is needed because of a serious adverse event, rapid discontinuation can be considered.
Patient Counseling Information
Advise the patient to read the FDA-approved patient labeling (Medication Guide).
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 changesinmoodorbehavior;orsuicidalthoughts,behavior,orthoughtsaboutself-harm.Advise patients,theircaregivers,and/or families to report behaviors of concern immediately to a healthcare provider [see WARNINGS AND PRECAUTIONS].
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 [see WARNINGS AND PRECAUTIONS].
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 [see WARNINGS AND PRECAUTIONS].
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 [see WARNINGS AND PRECAUTIONS].
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 [see WARNINGS AND PRECAUTIONS].
Advise patientstonotifytheirhealthcareprovideriftheybecomepregnantorintendtobecomepregnantduringBRIVIACT 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 [see Use In Specific Populations].
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 [see DOSAGE AND ADMINISTRATION].
Advise patients that the dosage of BRIVIACT oral solution should be measured using a calibrated measuring device and not a house hold teaspoon. Instruct patients to discard any unused BRIVIACT oralsolutionafter5monthsoffirstopeningthebottle [see DOSAGE AND ADMINISTRATION].
Carcinogenesis, Mutagenesis, Impairment Of Fertility
In a carcinogenicity study in mice, oral administration of brivaracetam (0, 400, 550, or 700 mg/kg/day) for 104 weeks increased the incidence of liver tumors (hepatocellular adenoma and carcinoma) in male mice at the two highest doses tested. At the dose (400 mg/kg) not associated with an increase in liver tumors, plasma exposures (AUC) were approximately equal to those in humans at the maximum recommended dose (MRD) of 200 mg/day. Oral administration (0, 150, 230, 450, or 700 mg/kg/day) to rats for 104 weeks resulted in an increased incidence of thymus tumors (benign thymoma) in female rats at the highest dose tested. At the highest dose not associated with an increase in thymus tumors, plasma exposures were approximately 9 times those in humans at the MRD.
Impairment Of Fertility
Oral administration of brivaracetam (0, 100, 200, or 400 mg/kg/day) to male and female rats prior to and throughout mating and early gestation produced no adverse effects on fertility. The highest dose tested was associated with plasma exposures approximately 6 (males) and 13 (females) times those in humans at the MRD.
Use In Specific Populations
Pregnancy Exposure Registry
There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to antiepileptic drugs (AEDs), such as BRIVIACT, during pregnancy. Encourage patients who are taking BRIVIACT during pregnancy to enroll in the North American Antiepileptic Drug (NAAED) Pregnancy Registry by calling the toll free number 1-888-233-2334 or visiting http://www.aedpregnancyregistry.org/.
There are no adequate data on the developmental risks associated with use of BRIVIACT in pregnant women. In animal studies, brivaracetam produced evidence of developmental toxicity (increased embryofetal mortality and decreased fetal body weights in rabbits; decreased growth, delayed sexual maturation, and long-term neurobehavioral changes in rat offspring) at maternal plasma exposures greater than clinical exposures [see Data].
In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. The background risk of major birth defects and miscarriage for the indicated population is unknown.
Oral administration of brivaracetam(0,150,300,or600mg/kg/day)to pregnant rats during the period of organogenesis did not produce any significant maternal or embryofetal toxicity. The highest dose tested was associated with maternal plasma exposures (AUC) approximately 30 times exposures in humans at the maximum recommended dose (MRD) of 200 mg/day.
Oral administration of brivaracetam (0, 30, 60, 120, or 240 mg/kg/day) to pregnant rabbits during the period of organogenesis resulted in embryofetal mortality and decreased fetal body weights at the highest dose tested, which was also maternally toxic. The highest no-effect dose (120 mg/kg/day) was associated with maternal plasma exposures approximately 4 times human exposures at the MRD.
When brivaracetam (0, 150, 300, or 600 mg/kg/day) was orally administered to rats throughout pregnancy and lactation, decreased growth, delayed sexual maturation (female), and long-term neurobehavioral changes were observed in the offspring at the highest dose. The highest no-effect dose (300 mg/kg/day) was associated with maternal plasma exposures approximately 7 times human exposures at the MRD.
Brivaracetam was shown to readily cross the placenta in pregnant rats after a single oral (5 mg/kg) dose of 14C-brivaracetam. From1 hour post dose, radioactivity levels in fetuses, amniotic fluid, and placenta were similar to those measured in maternal blood.
No data are available regarding the presence of brivaracetam inhuman milk, the effects on the breastfed infant, or the effects of the drug on milk production. Studies in lactatingrats have shown excretionof brivaracetam or metabolites in milk [see Data].
The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for BRIVIACT and any potential adverse effectson the breastfed infant from BRIVIACT or from the underlying maternal condition.
Following a single oral (5 mg/kg) dose of 14C-brivaracetam to lactating rats, radioactivity was secreted in milkand rapidly reached levels similar to those in plasma.
Safety and effectiveness of BRIVIACT tablets and oral solution have been established in pediatric patients 4 years to less than 16 years of age. Use of BRIVIACT in these age groups is supported by evidence from adequate and well-controlled studies of BRIVIACT in adults with partial-onset seizures, pharmacokinetic data from adult and pediatric patients, and safety data in 149 pediatric patients 4 years to less than 16 years of age [see DOSAGE AND ADMINISTRATION, WARNINGS AND PRECAUTIONS, ADVERSE REACTIONS, and CLINICAL PHARMACOLOGY].
Safety of BRIVIACT injection in pediatric patients has not been established.
Safety and effectiveness in pediatric patients below the age of 4 years have not been established.
Juvenile Animal Toxicity Data
The potential adverse effects of brivaracetam on postnatal growth and development were investigated in juvenile rats and dogs. Oral administration (0, 150, 300, or 600mg/kg/day) to rats during the neonatal and juvenile periods of development (approximately equivalent to neonatal through adolescent development in humans) resulted in increased mortality, decreased body weight gain, delayed male sexual maturation, and adverse neurobehavioral effects at the highest dose tested and decreased brain size and weight at all doses. Therefore, ano-effect dose was not established; the lowest dose tested in juvenile rats was associated with plasma exposures (AUC) approximately 2 times those in children and adolescents at the recommended maintenance dose. In dogs, oral administration (0, 15, 30, or 100 mg/kg/day) throughout the neonatal and juvenile periods of development induced liver changes similar to those observed in adult animals at the highest dose but produced no adverse effects on growth, bone density or strength, neurological testing, or neuropathology evaluation. The overall no-effect dose(30 mg/kg/day) and the no-effect dose for adverse effects on developmental parameters (100 mg/kg/day) were associated with plasma exposures approximately equal to and 4 times, respectively, those in children and adolescents at the recommended maintenance dose.
There were insufficient numbers of patients 65 years of age and older in the double-blind, placebo-controlled epilepsytrials (n=38) to allow adequate assessment of the effectiveness of BRIVIACT in this population. In general, dose selection for an elderly patient should be judicious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy [see CLINICAL PHARMACOLOGY].
Dose adjustments are not required for patients with impaired renal function. There are no data in patients with end-stage renal disease undergoing dialysis, and use of BRIVIACT is not recommended in this patient population [see CLINICAL PHARMACOLOGY].
Because of increases in BRIVIACT exposure, dosage adjustment is recommended for all stages of hepatic impairment [see WARNINGS AND PRECAUTIONS and CLINICAL PHARMACOLOGY].
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.
Hypersensitivity to brivaracetam or any of the inactive ingredients in BRIVIACT (bronchospasm and angioedema have occurred) [see WARNINGS AND PRECAUTIONS].
Mechanism Of Action
The precise mechanism by which BRIVIACT exerts its anticonvulsant activity is not known. Brivaracetam displays a high and selective affinity for synaptic vesicle protein 2A(SV2A) in the brain, which may contribute to the anticonvulsant effect.
Interactions With Alcohol
In a pharmacokinetic and pharmacodynamic interaction study in healthy subjects, co-administration of BRIVIACT (single dose 200 mg [2 times greater than the highest recommended single dose]) and ethanol (continuous intravenous infusion to achieve a blood alcohol concentration of 60 mg/100 mL during 5 hours) increased the effects of alcohol on psychomotor function, attention, and memory. Co-administration of BRIVIACT and ethanol caused a larger decrease from baseline in saccadic peak velocity, smooth pursuit, adaptive tracking performance, and Visual Analog Scale (VAS) alertness, and a larger increase from baseline in body sway and in saccadic reaction time compared with BRIVIACT alone or ethanol alone. The immediate word recall scores were generally lower for BRIVIACT when co-administered with ethanol.
At a dose 4 times the maximum recommended dose, BRIVIACT did not prolong the QT interval to a clinically relevant extent.
BRIVIACT tablets, oral solution, and injection can be used interchangeably. Brivaracetam exhibits linear and time-independent pharmacokinetics at the approved doses.
The pharmacokinetics of brivaracetam are similar when used as mono therapy or as adjunctive therapy for the treatment of partial-onset seizures.
Brivaracetam is highly permeable and is rapidly and almost completely absorbed after oral administration. Pharmacokinetics is dose-proportional from 10 to 600 mg (a range that extends beyond the minimum and maximum single-administration dose levels described in Dosage and Administration [see DOSAGE AND ADMINISTRATION]). The median Tmax for tablets taken without food is 1 hour (range 0.25 to 3 hours). Co-administration with a high-fat meal slowed absorption, but the extent of absorption remained unchanged. Specifically, when a 50 mg tablet was administered with a high-fat meal, Cmax (maximum brivaracetam plasma concentration during a dose interval, an exposure metric) was decreased by 37% and Tmax was delayed by 3 hours, but AUC (area under the brivaracetam plasma concentration versus time curve, an exposure metric) was essentially unchanged (decreased by 5%).
Brivaracetam is weakly bound to plasma proteins (≤20%). The volume of distribution is 0.5 L/kg, a value close to that of the total body water. Brivaracetam is rapidly and evenly distributed in most tissues.
Brivaracetam is primarily metabolized by hydrolysis of the amide moiety to form the corresponding carboxylic acid metabolite, and secondarily by hydroxylation on the propyl side chain to form the hydroxy metabolite. The hydrolysis reaction is mediated by hepatic and extra-hepatic amidase. The hydroxylation pathway is mediated primarily by CYP2C19. In human subjects possessing genetic variations in CYP2C19, production of the hydroxy metabolite is decreased 2-fold or 10-fold, while the bloodlevel of brivaracetam itself is increased by 22% or 42%, respectively, inindividuals with one or both mutated alleles. CYP2C19 poor metabolizers and patients using inhibitors of CYP2C19 may require dose reduction. An additional hydroxy acid metabolite is created by hydrolysis of the amide moiety on the hydroxyl metabolite or hydroxylation of the propyl side chain on the carboxylic acid metabolite (mainly by CYP2C9). None of the 3 metabolites are pharmacologically active.
Brivaracetam is eliminated primarily by metabolism and by excretionin the urine. More than 95% of the dose, including metabolites, is excreted in the urine within 72 hours after intake. Fecal excretion accounts for less than 1% of the dose. Less than 10% of the dose is excreted unchanged in the urine. Thirty-four percent of the dose is excreted as the carboxylic acid metabolite in urine. The terminal plasma half-life (t½) is approximately 9 hours.
Anopen-label, single-arm, multicenter, pharmacokinetic
study with a 3-weekevaluation period and fixed 3 step up-titration using BRIVIACT
oral solution was conducted in 59 pediatric patients 4 years to less than 16
years of age. In those patients, plasma concentrations were shown to be
dose-proportional. A weight-based dosing regimen is necessary to achieve
brivaracetam exposures inpediatric patients 4 years to less than 16 years of
age that are similar to those observed in adults treated at effective
of BRIVIACT [see DOSAGE AND ADMINISTRATION]. The estimated plasma
clearance was 1.61 L/h; 2.18 L/h; 3.19 L/h for pediatric patients weighing 20
kg, 30 kg, and 50 kg, respectively. In comparison, plasma clearance was
estimated at 3.58 L/h in adult patients (70 kg body weight).
Ina study in elderly subjects (65 to 79 years old; creatinine clearance 53 to 98 mL/min/1.73 m²) receiving BRIVIACT 200 mg twice daily (2 times the highest recommended dosage), the plasma half-life of brivaracetam was 7.9 hours and 9.3 hours in the 65 to 75 and >75 years groups, respectively. The steady-state plasma clearance of brivaracetam was slightly lower (0.76 mL/min/kg) than in young healthy controls (0.83 mL/min/kg).
There were no differences observed in the pharmacokinetics of brivaracetam between male and female subjects.
A population pharmacokinetic analysis comparing Caucasian and non-Caucasian patients showed no significant pharmacokinetic difference.
A study in adult subjects with severe renal impairment (creatinine clearance<30 mL/min/1.73m² and not requiring dialysis) revealed that the plasma AUC of brivaracetam was moderately increased(21%) relative to healthy controls, while the AUCs of the acid, hydroxy, and hydroxyacidmetaboliteswereincreased3-fold,4-fold,and21-fold,respectively.Therenal clearance of these inactive metabolites was decreased 10-fold. Brivaracetam has not been studied in patients undergoing hemodialysis [see Use In Specific Populations].
A pharmacokinetic study in adult subjects with hepatic cirrhosis, Child-Pugh grades A, B, and C, showed 50%, 57%, and 59% increases in brivaracetam exposure, respectively, compared to matched healthy controls. The effect of hepatic impairment on brivaracetam pharmacokinetics in pediatric patients is expected to be comparable to the effect observed in adults [see DOSAGE AND ADMINISTRATION and Use In Specific Populations].
Drug Interaction Studies
In Vitro Assessment Of Drug Interactions
Drug-Metabolizing Enzyme Inhibition
Brivaracetam did not inhibit CYP1A2, 2A6, 2B6, 2C8, 2C9, 2D6, or 3A4. Brivaracetam weakly inhibited CYP2C19 and would not be expected to cause significant inhibitionof CYP2C19 in humans. Brivaracetam was an inhibitor of epoxide hydrolase, (IC50 = 8.2 μM), suggesting that brivaracetam can inhibit the enzyme in vivo.
Drug-Metabolizing Enzyme Induction
Brivaracetam at concentrations up to 10 μM caused little or no change of mRNA expression of CYP1A2, 2B6, 2C9, 2C19, 3A4, and epoxide hydrolase. It is unlikely that brivaracetam will induce these enzymes in vivo.
Brivaracetam was not a substrate of P-gp, MRP1, or MRP2. Brivaracetam did not inhibit or weakly inhibit BCRP, BSEP, MATE1, MATE2/K, MRP2, OAT1, OAT3, OCT1, OCT2, OATP1B1, OATP1B3, or P-gp, suggesting that brivaracetam is unlikely to inhibit these transporters in vivo.
In Vivo Assessment Of Drug Interactions
Drug Interaction Studies with Antiepileptic Drugs (AEDs)
Potential interactions between BRIVIACT (25 mg twice daily to 100 mg twice daily) and other AEDs were investigated in a pooled analysis of plasma drug concentrations from all Phase 2 and 3 studies and in a population exposure-response analysis of placebo-controlled, Phase 3 studies in adjunctive therapy in the treatment of partial-onset seizures. None of the interactions require changes in the dose of BRIVIACT. Interactions with carbamazepine and phenytoin can be clinically important [see DRUG INTERACTIONS]. The interactions are summarized in Table 4.
Table 4: Drug Interactions Between BRIVIACT and Concomitant
|Concomitant AED||Influence of AED on BRIVIACT||Influence of BRIVIACT on AED|
|Carbamazepine||26% decrease in plasma concentration||None for carbamazepine Increase of carbamazepine-epoxide metabolite* [see DRUG INTERACTIONS]|
|Oxcarbazepine||None||None on the active monohydroxy metabolite derivative (MHD)|
|Phenobarbital||19% decrease in plasma concentration||None|
|Phenytoin||21% decrease in plasma concentration||Up to 20% increase in plasma concentration [see DRUG INTERACTIONS]**|
|* Brivaracetam is a reversible inhibitor of epoxide
hydrolase resulting in an increased concentration of carbamazepine epoxide, an
active metabolite of carbamazepine. The carbamazepine epoxide plasma
concentration increased up to 198% at a BRIVIACT dose of 100 mg twice daily.
** At a supratherapeutic dose of 400 mg/day brivaracetam, there was a 20% increase in phenytoin plasma concentration.
Drug Interaction Studies With Other Drugs
Effect Of Other Drugs On BRIVIACT
Co-administration with CYP inhibitors or transporter inhibitors is unlikely to significantly affect brivaracetam exposure.
Co-administration of BRIVIACT 200 mg twice daily (twice the recommended maximum daily dosage) with an oral contraceptive containing ethinylestradiol (0.03 mg) and levonorgestrel (0.15 mg) reduced estrogen and progestin AUCs by 27% and 23%, respectively, without impact on suppression of ovulation. However, co-administration of BRIVIACT 50 mg twice daily with an oral contraceptive containing ethinylestradiol (0.03 mg) and levonorgestrel (0.15 mg) did not significantly influence the pharmacokinetics of either substance. The interaction is not expected to be of clinical significance.
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 out come 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 5 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.

Response for BRIVIACT and Placebo Across all Three Double Blind Trials
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.

What is the most important information I should know about BRIVIACT?
BRIVIACT is a federally controlled substance (CV) because it can be abused or lead to dependence. Keep BRIVIACT in a safe place to prevent misuse and abuse. Selling or giving away BRIVIACT may harm others and is against the law.
Like other antiepileptic drugs, BRIVIACT may cause suicidal thoughts or actions in a very small number of people, about 1 in 500 people taking it.
Call a 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
- new or worse depression
- feeling agitated or restless
- trouble sleeping (insomnia)
- acting aggressive, feeling angry, or being violent
- an extreme increase in activity and talking (mania)
- attempts to commit suicide
- new or worse anxiety
- panic attacks
- new or worse irritability
- acting on dangerous impulses
- other unusual changes in behavior or mood
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.
How can I watch for early symptoms of suicidal thoughts and actions?
