Results showed that FINTEPLA was generally well tolerated. The most common treatment-emergent adverse events (TEAEs) were pyrexia, nasopharyngitis and decreased appetite.2 The efficacy analysis showed a statistically significant and clinically meaningful sustained reduction in monthly convulsive seizure frequency (MCSF) with FINTEPLA in both children and adults with DS.2 FINTEPLA® (fenfluramine) is approved by the U.S. Food and Drug Administration (FDA) for the treatment of seizures associated with Dravet syndrome and Lennox-Gastaut syndrome in patients two years of age and older. (PRNewsfoto/UCB) "Anti-seizure medications that provide long-term tolerability and effectiveness are needed for patients with DS, who often have many other medical conditions that are adversely impacted by seizure frequency and severity," said Ingrid E. Scheffer, MBBS, Ph.D., co-author of the publication and laureate professor, chair of pediatric neurology at the University of Melbourne. "This analysis, showing that FINTEPLA was generally well tolerated over the long-term and increased seizure-free days, builds on previous findings from randomized, controlled trials in adults and children with DS and provides additional evidence of the sustained tolerability and efficacy of this treatment." The OLE study enrolled patients with DS who had participated in one of three randomized, placebo-controlled Phase 3 trials of FINTEPLA or who were 19 to 35 years old and had not received FINTEPLA prior to study entry. The primary objective of the OLE study was to assess the long-term safety and tolerability of FINTEPLA. Efficacy endpoints evaluated the median percentage change in MCSF from Day 1 to end of study (EOS) and Day 31 to EOS compared with baseline; the proportion of patients to achieve seizure reduction thresholds; the longest convulsive seizure-free interval; and the percentage of convulsive seizure-free days in the modified intent-to-treat (mITT) population. Clinical Global Impression-Improvement (CGI-I) ratings by caregiver and investigator and changes in baseline in the Quality of Life Childhood Epilepsy (QOLCE) score were also evaluated. Results showed that FINTEPLA was generally well tolerated with only 11 patients (2.9%) discontinuing therapy due to an adverse event. TEAEs occurring in ≥10% of patients were pyrexia, nasopharyngitis, decreased appetite, seizure, decreased blood glucose, diarrhea, abnormal echocardiogram (only physiologic regurgitation), upper respiratory tract infection, influenza, vomiting, and ear infection. No valvular heart disease or pulmonary arterial hypertension was observed in this study. Efficacy outcomes showed a sustained reduction in MCSF with FINTEPLA in the mITT population of 324 patients, with a median change from Day 1 to EOS compared with baseline of -66.8% (p<0.001) and -67.8% (p<0.001) from Day 31 to EOS compared with baseline. FINTEPLA was effective in both patients less than six years old and those six years or older. The analysis showed that 64.2% of patients experienced a 50% or more reduction in MCSF; two patients were seizure-free throughout the OLE. From Month 1 to EOS, there was a significant 20.3% median increase in convulsive seizure-free days (p<0.0001). Caregivers rated 61.3% of patients as much/very much improved at the last visit on the CGI-I, as did 62.6% of investigators. Significant improvements from baseline were observed in several subscales of the QOLCE, including energy/fatigue, language, general health, QOL and overall QOL. DS is a rare, severe, drug-resistant developmental and epileptic encephalopathy (DEE) that is characterized by seizure onset before the first year of life and developmental slowing or regression.4,5 DS is often challenging to diagnose.6 Patients often experience multiple seizure types5 and effects beyond seizures, including cognitive impairment, speech impairment, sleep and gait issues, and behavioral issues, including impulsivity and hyperactivity, that can adversely impact quality of life.5-7 "The ability to meaningfully address the complexities of Dravet, inclusive of the severe and often debilitating seizures, is critical for patients living with this rare syndrome and those who care for them," said Brad Chapman, head of U.S. epilepsy and rare syndromes at UCB. "The publication of these new long-term findings, in which patients were exposed to FINTEPLA for up to 3.5 years and experienced durable and clinically meaningful reductions in seizure frequency, emphasizes the benefit of this treatment and our commitment to helping improve outcomes for patients with DS and other rare epilepsies." About FINTEPLA Important Safety Information about FINTEPLA® (fenfluramine) in the US INDICATIONS AND USAGE FINTEPLA is indicated for the treatment of seizures associated with Dravet syndrome (DS) and Lennox-Gastaut syndrome (LGS) in patients 2 years of age and older. IMPORTANT SAFETY INFORMATION BOXED WARNING: VALVULAR HEART DISEASE and PULMONARY ARTERIAL HYPERTENSION There is an association between serotonergic drugs with 5-HT2B receptor agonist activity, including fenfluramine (the active ingredient in FINTEPLA), and valvular heart disease and pulmonary arterial hypertension. Echocardiogram assessments are required before, during, and after treatment with FINTEPLA. FINTEPLA is available only through a restricted program called the FINTEPLA REMS. CONTRAINDICATIONS FINTEPLA is contraindicated in patients with hypersensitivity to fenfluramine or any of the excipients in FINTEPLA and with concomitant use, or within 14 days of the administration, of monoamine oxidase inhibitors because of an increased risk of serotonin syndrome. WARNINGS AND PRECAUTIONS Valvular Heart Disease and Pulmonary Arterial Hypertension (see Boxed Warning): Because of the association between serotonergic drugs with 5-HT2B receptor agonist activity, including fenfluramine (the active ingredient in FINTEPLA), and valvular heart disease (VHD) and pulmonary arterial hypertension (PAH), cardiac monitoring via echocardiogram is required prior to starting treatment, during treatment, and after treatment with FINTEPLA concludes. Cardiac monitoring via echocardiogram can aid in early detection of these conditions. In clinical trials for DS and LGS of up to 3 years in duration, no patient receiving FINTEPLA developed VHD or PAH. Monitoring: Prior to starting treatment, patients must undergo an echocardiogram to evaluate for VHD and PAH. Echocardiograms should be repeated every 6 months, and once at 3-6 months post treatment with FINTEPLA. The prescriber must consider the benefits versus the risks of initiating or continuing treatment with FINTEPLA if any of the following signs are observed via echocardiogram: valvular abnormality or new abnormality; VHD indicated by mild or greater aortic regurgitation or moderate or greater mitral regurgitation, with additional characteristics of VHD (eg, valve thickening or restrictive valve motion); PAH indicated by elevated right heart/pulmonary artery pressure (PASP >35 mmHg). FINTEPLA REMS Program (see Boxed Warning): FINTEPLA is available only through a restricted distribution program called the FINTEPLA Risk Evaluation and Mitigation Strategy (REMS) Program. Prescribers must be certified by enrolling in the FINTEPLA REMS. Prescribers must counsel patients receiving FINTEPLA about the risk of VHD and PAH, how to recognize signs and symptoms of VHD and PAH, the need for baseline (pretreatment) and periodic cardiac monitoring via echocardiogram during FINTEPLA treatment, and cardiac monitoring after FINTEPLA treatment. Patients must enroll in the FINTEPLA REMS and comply with ongoing monitoring requirements. The pharmacy must be certified by enrolling in the FINTEPLA REMS and must only dispense to patients who are authorized to receive FINTEPLA. Wholesalers and distributors must only distribute to certified pharmacies. Further information is available at or by telephone at 1-877-964-3649. Decreased Appetite and Decreased Weight: FINTEPLA can cause decreases in appetite and weight. Decreases in weight appear to be dose related. Approximately half of the patients with LGS and most patients with DS resumed the expected measured increases in weight during the open-label extension studies. Weight should be monitored regularly during treatment with FINTEPLA, and dose modifications should be considered if a decrease in weight is observed. Somnolence, Sedation, and Lethargy: FINTEPLA can cause somnolence, sedation, and lethargy. Other central nervous system (CNS) depressants, including alcohol, could potentiate these effects of FINTEPLA. Prescribers should monitor patients for somnolence and sedation and should advise patients not to drive or operate machinery until they have gained sufficient experience on FINTEPLA to gauge whether it adversely affects their ability to drive or operate machinery. Suicidal Behavior and Ideation: Antiepileptic drugs (AEDs), including FINTEPLA, increase the risk of suicidal thoughts or behaviors in patients taking these drugs for any indication. Patients treated with an AED for any indication should be monitored for the emergence or worsening of depression, suicidal thoughts or behaviors, or any unusual changes in mood or behavior. Anyone considering prescribing FINTEPLA or any other AED must balance the risk of suicidal thoughts or behaviors with the risks 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 behaviors. Should suicidal thoughts and behaviors emerge during treatment, consider whether the emergence of these symptoms in any given patient may be related to the illness being treated. Withdrawal of Antiepileptic Drugs: As with most AEDs, FINTEPLA should generally be withdrawn gradually because of the risk of increased seizure frequency and status epilepticus. If withdrawal is needed because of a serious adverse reaction, rapid discontinuation can be considered. Serotonin Syndrome: Serotonin syndrome, a potentially life-threatening condition, may occur with FINTEPLA, particularly during concomitant administration of FINTEPLA with other serotonergic drugs, including, but not limited to, selective serotonin-norepinephrine reuptake inhibitors (SNRIs), selective serotonin reuptake inhibitors (SSRIs), tricyclic antidepressants (TCAs), bupropion, triptans, dietary supplements (eg, St. John's Wort, tryptophan), drugs that impair metabolism of serotonin (including monoamine oxidase inhibitors [MAOIs], which are contraindicated with FINTEPLA), dextromethorphan, lithium, tramadol, and antipsychotics with serotonergic agonist activity. Patients should be monitored for the emergence of signs and symptoms of serotonin syndrome, which include mental status changes (eg, agitation, hallucinations, coma), autonomic instability (eg, tachycardia, labile blood pressure, hyperthermia), neuromuscular signs (eg, hyperreflexia, incoordination), and/or gastrointestinal symptoms (eg, nausea, vomiting, diarrhea). If serotonin syndrome is suspected, treatment with FINTEPLA should be stopped immediately and symptomatic treatment should be started. Increase in Blood Pressure: FINTEPLA can cause an increase in blood pressure. Rare cases of significant elevation in blood pressure, including hypertensive crisis, has been reported in adult patients treated with fenfluramine, including patients without a history of hypertension. In clinical trials for DS and LGS of up to 3 years in duration, no pediatric or adult patient receiving FINTEPLA developed hypertensive crisis. Monitor blood pressure in patients treated with FINTEPLA. Glaucoma: Fenfluramine can cause mydriasis and can precipitate angle closure glaucoma. Consider discontinuing treatment with FINTEPLA in patients with acute decreases in visual acuity or ocular pain. ADVERSE REACTIONS The most common adverse reactions observed in DS studies (incidence at least 10% and greater than placebo) were decreased appetite; somnolence, sedation, lethargy; diarrhea; constipation; abnormal echocardiogram; fatigue, malaise, asthenia; ataxia, balance disorder, gait disturbance; blood pressure increased; drooling, salivary hypersecretion; pyrexia; upper respiratory tract infection; vomiting; decreased weight; fall; status epilepticus. The most common adverse reactions observed in the LGS study (incidence at least 10% and greater than placebo) were diarrhea; decreased appetite; fatigue; somnolence; vomiting. DRUG INTERACTIONS Strong CYP1A2, CYP2B6, or CYP3A Inducers: Coadministration with strong CYP1A2, CYP2B6, or CYP3A inducers will decrease fenfluramine plasma concentrations. If coadministration of a strong CYP1A2, CYP2B6, or CYP3A inducer with FINTEPLA is necessary, monitor the patient for reduced efficacy and consider increasing the dosage of FINTEPLA as needed. If a strong CYP1A2, CYP2B6, or CYP3A inducer is discontinued during maintenance treatment with FINTEPLA, consider gradual reduction in the FINTEPLA dosage to the dose administered prior to initiating the inducer. Strong CYP1A2 or CYP2D6 Inhibitors: Coadministration with strong CYP1A2 or CYP2D6 inhibitors will increase fenfluramine plasma concentrations. If FINTEPLA is coadministered with strong CYP1A2 or CYP2D6 inhibitors, the maximum daily dosage of FINTEPLA is 20 mg. If a strong CYP1A2 or CYP2D6 inhibitor is discontinued during maintenance treatment with FINTEPLA, consider gradual increase in the FINTEPLA dosage to the dose recommended without CYP1A2 or CYP2D6 inhibitors. If FINTEPLA is coadministered with stiripentol and a strong CYP1A2 or CYP2D6 inhibitor, the maximum daily dosage of FINTEPLA is 17 mg. USE IN SPECIFIC POPULATIONS In patients with severe impairment of kidney function (estimated glomerular filtration rate [eGFR]) 15 to 29 mL/min/1.73m2, dosage adjustments are recommended. FINTEPLA has not been studied in patients with kidney failure (eGFR <15 mL/min/1.73m2). Combined molar exposures of fenfluramine and norfenfluramine were increased in subjects with various degrees of hepatic impairment (Child-Pugh Class A, B, and C), necessitating a dosage adjustment in these patients.
