About FINTEPLA^=C2=AE (fenfluramine) C-IV FINTEPLA^=C2=AE (fenfluramine) oral solution is a prescription medication a= pproved by the FDA and authorized by the EU Commission, and under regulator= y review with the PMDA (Japan), for the treatment of seizures associated wi= th Dravet syndrome in patients two years of age and older.^8,12 A Type II V= ariation Application has also been submitted to the European Medicines Agen= cy (EMA) for the treatment of seizures associated with LGS.^13 In the United States, FINTEPLA is available only through a restricted distr= ibution program called the FINTEPLA REMS program. FINTEPLA is available in = EU under a controlled access program requested by the EMA to prevent off-la= bel use for weight management and to confirm that prescribing physicians ha= ve been informed of the need for periodic cardiac monitoring in patients ta= king FINTEPLA.

Aortic or mitral valvular heart disease. Pulmonary arterial h= ypertension. 4 Within 14 days of the administration of monoamine oxidase in= hibitors due to an increased risk of serotonin syndrome Summary of the safety profile=C2=A0 The most commonly reported adverse reactions are decreased appetite (44.2%)= , diarrhoea (30.8%), pyrexia (25.6%), fatigue (25.6%), upper respiratory tr= act infection (20.5%), lethargy (17.5%), somnolence (15.4%), and bronchitis= (11.6%) Special warnings and precautions for use Aortic or mitral valvular heart disease and pulmonary arterial hypertension Because of reported cases of valvular heart disease that may have been caus= ed by fenfluramine at higher doses used to treat adult obesity, cardiac mon= itoring must be performed using echocardiography. In the controlled clinica= l studies of fenfluramine for the treatment of Dravet syndrome, no valvular= heart disease was observed. Prior to starting treatment, patients must undergo an echocardiogram to est= ablish a baseline prior to initiating treatment (see section 4.3) and exclu= de any pre-existing valvular heart disease or pulmonary hypertension. Echocardiogram monitoring should be conducted every 6 months for the first = 2 years and annually thereafter. If an echocardiogram indicates pathologica= l valvular changes, a follow-up echocardiogram should be considered at an e= arlier timeframe to evaluate whether the abnormality is persistent. If path= ological abnormalities on the echocardiogram are observed, it is recommende= d to evaluate the benefit versus risk of continuing fenfluramine treatment = with the prescriber, caregiver, and cardiologist. If treatment is stopped because of aortic or mitral valvular heart disease,= appropriate monitoring and follow-up should be provided in accordance with= local guidelines for the treatment of aortic or mitral valvular heart dise= ase. With past use in higher doses to treat adult obesity, fenfluramine was repo= rted to be associated with pulmonary arterial hypertension. Pulmonary arter= ial hypertension was not observed in the clinical programme, but because of= the low incidence of this disease, the clinical trial experience with fenf= luramine is inadequate to determine if fenfluramine increases the risk for = pulmonary arterial hypertension in patients with Dravet syndrome. If echoca= rdiogram findings are suggestive of pulmonary arterial hypertension, a repe= at echocardiogram should be performed as soon as possible and within 3 mont= hs to confirm these findings. If the echocardiogram finding is confirmed su= ggestive of an increased probability of pulmonary arterial hypertension def= ined as =E2=80=9Cintermediate probability=E2=80=9D by the 2015 European Soc= iety of Cardiology (ESC) and the European Respiratory Society (ERS) Guideli= nes, it should lead to a benefit-risk evaluation of continuation of Fintepl= a by the prescriber, carer, and cardiologist. If the echocardiogram finding= , after confirmation, suggests of a high probability of pulmonary arterial = hypertension, as defined by the 2015 ESC and ERS Guidelines, it is recommen= ded fenfluramine treatment should be stopped. Decreased appetite and weight loss Fenfluramine can cause decreased appetite and weight loss (see section 4.8)= . An additive effect on decreased appetite can occur when fenfluramine is c= ombined with other anti-epileptic medicines, for example stiripentol. The d= ecrease in weight appears to be dose related. Most subjects resumed weight = gain over time while continuing treatment. The patient's weight should be m= onitored. A benefit risk evaluation should be undertaken prior to commencin= g treatment with fenfluramine in patients with a history of anorexia nervos= a or bulimia nervosa. Fintepla controlled access programme A controlled access programme has been created to 1) prevent off-label use = in weight management in obese patients and 2) confirm that prescribing phys= icians have been informed of the need for periodic cardiac monitoring in pa= tients taking Fintepla. Somnolence Fenfluramine can cause somnolence. Other central nervous system depressants, including alcohol, could potentia= te the somnolence effect of fenfluramine (see sections 4.5 and 4.7). Suicidal behaviour and ideation Suicidal behaviour and ideation have been reported in patients treated with= anti-epileptic medicines in several indications. A meta-analysis of random= ised placebo-controlled trials with anti-epileptic medicines that did not i= nclude fenfluramine has shown a small increased risk of suicidal behaviour = and ideation. The mechanism of this risk is not known, and the available da= ta do not exclude the possibility of an increased risk for fenfluramine. Pa= tients and caregivers of patients should be advised to seek medical advice = should any signs of suicidal behaviour and ideation emerge. Serotonin syndrome As with other serotonergic agents, serotonin syndrome, a potentially life-t= hreatening condition, may occur with fenfluramine treatment, particularly w= ith concomitant use of other serotonergic agents (including SSRIs, SNRIs, t= ricyclic antidepressants, or triptans); with agents that impair metabolism = of serotonin such as MAOIs; or with antipsychotics that may affect the sero= tonergic neurotransmitter systems (see sections 4.3 and 4.5). Serotonin syndrome symptoms may include mental status changes (eg, agitatio= n, hallucinations, coma), autonomic instability (eg, tachycardia, labile bl= ood pressure, hyperthermia), neuromuscular aberrations (eg, hyperreflexia, = incoordination), and/or gastrointestinal symptoms (eg, nausea, vomiting, di= arrhoea). If concomitant treatment with fenfluramine and other serotonergic agents th= at may affect the serotonergic systems is clinically warranted, careful obs= ervation of the patient is advised, particularly during treatment initiatio= n and dose increases. Increased seizure frequency As with other anti-epileptic medicines, a clinically relevant increase in s= eizure frequency may occur during treatment with fenfluramine, which may re= quire adjustment in the dose of fenfluramine and/or concomitant anti-epilep= tic medicines, or discontinuation of fenfluramine, should the benefit-risk = be negative. Cyproheptadine Cyproheptadine is a potent serotonin receptor antagonist and may therefore = decrease the efficacy of fenfluramine. If cyproheptadine is added to treatm= ent with fenfluramine, patients should be monitored for worsening of seizur= es. If fenfluramine treatment is initiated in a patient taking cyproheptadi= ne, fenfluramine's efficacy may be reduced. Glaucoma Fenfluramine can cause mydriasis and can precipitate angle closure glaucoma= . Discontinue therapy in patients with acute decreases in visual acuity. Co= nsider discontinuation if there is ocular pain and another cause cannot be = determined. Strong CYP1A2 or CYP2B6 inducers Co-administration with strong CYP1A2 inducers or CYP2B6 inducers may decrea= se fenfluramine plasma concentrations (see section 4.5). An increase in fenfluramine dosage should be considered when co-administere= d with a strong CYP1A2 or CYP2B6 inducer; the maximum daily dose should not= be exceeded. Excipients This medicinal product contains sodium ethyl para-hydroxybenzoate (E 215) a= nd sodium methyl para-hydroxybenzoate (E 219) which may cause allergic reac= tions (possibly delayed). It also contains sulfur dioxide (E 220) which may rarely cause severe hyper= sensitivity reactions and bronchospasm.

IMPORTANT SAFETY INFORMATION BOXED WARNING: VALVULAR HEART DISEASE and PULMONARY ARTERIAL HYPERTENSION =C2=B7 There is an association between serotonergic drugs with 5-HT2B recep= tor agonist activity, including fenfluramine (the active ingredient in FINT= EPLA), and valvular heart disease and pulmonary arterial hypertension.=C2= =A0 =C2=B7 Echocardiogram assessments are required before, during, and after tr= eatment with FINTEPLA.=C2=A0 =C2=B7 FINTEPLA is available only through a restricted program called the F= INTEPLA REMS. CONTRAINDICATIONS FINTEPLA is contraindicated in patients with hypersensitivity to fenflurami= ne or any of the excipients in FINTEPLA and with concomitant use, or within= 14 days of the administration of monoamine oxidase inhibitors because of a= n increased risk of serotonin syndrome. WARNINGS AND PRECAUTIONS Valvular Heart Disease and Pulmonary Arterial Hypertension (see Boxed Warni= ng): Because of the association between serotonergic drugs with 5 HT2B rece= ptor agonist activity, including fenfluramine (the active ingredient in FIN= TEPLA), and valvular heart disease (VHD) and pulmonary arterial hypertensio= n (PAH), cardiac monitoring via echocardiogram is required prior to startin= g 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 echocardi= ogram 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 obser= ved via echocardiogram: valvular abnormality or new abnormality; VHD indica= ted by mild or greater aortic regurgitation or moderate or greater mitral r= egurgitation, with additional characteristics of VHD (eg, valve thickening = or restrictive valve motion); PAH indicated by elevated right heart/pulmona= ry artery pressure (PASP >35mmHg). FINTEPLA REMS Program (see Boxed Warning): FINTEPLA is available only throu= gh a restricted distribution program called the FINTEPLA Risk Evaluation an= d Mitigation Strategy (REMS) Program. Prescribers must be certified by enro= lling in the FINTEPLA REMS. Prescribers must counsel patients receiving FIN= TEPLA about the risk of valvular heart disease and pulmonary arterial hyper= tension, how to recognize signs and symptoms of valvular heart disease and = pulmonary arterial hypertension, the need for baseline (pretreatment) and p= eriodic cardiac monitoring via echocardiogram during FINTEPLA treatment, an= d 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 distri= butors must only distribute to certified pharmacies. Further information is= available at www.FinteplaREMS.com or by telephone at 1-877-964-3649. Decreased Appetite and Decreased Weight: FINTEPLA can cause decreases in ap= petite and weight. Decreases in weight appear to be dose related. Approxima= tely half of the patients with LGS and most patients with DS resumed the ex= pected 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= .=C2=A0 Somnolence, Sedation, and Lethargy: FINTEPLA can cause somnolence, sedation= , and lethargy. Other central nervous system (CNS) depressants, including a= lcohol, could potentiate these effects of FINTEPLA. Prescribers should moni= tor 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 op= erate machinery. Suicidal Behavior and Ideation: Antiepileptic drugs (AEDs), including FINTE= PLA, increase the risk of suicidal thoughts or behaviors in patients taking= these drugs for any indication. Patients treated with an AED for any indic= ation should be monitored for the emergence or worsening of depression, sui= cidal thoughts or behaviors, or any unusual changes in mood or behavior. Anyone considering prescribing FINTEPLA or any other AED must balance the r= isk of suicidal thoughts or behaviors with the risks of untreated illness. = Epilepsy and many other illnesses for which AEDs are prescribed are themsel= ves associated with morbidity and mortality and an increased risk of suicid= al thoughts and behaviors. Should suicidal thoughts and behaviors emerge du= ring treatment, consider whether the emergence of these symptoms in any giv= en patient may be related to the illness being treated. Withdrawal of Antiepileptic Drugs: As with most AEDs, FINTEPLA should gener= ally be withdrawn gradually because of the risk of increased seizure freque= ncy and status epilepticus. If withdrawal is needed because of a serious ad= verse reaction, rapid discontinuation can be considered. Serotonin Syndrome: Serotonin syndrome, a potentially life-threatening cond= ition, may occur with FINTEPLA, particularly during concomitant administrat= ion of FINTEPLA with other serotonergic drugs, including, but not limited t= o, selective serotonin-norepinephrine reuptake inhibitors (SNRIs), selectiv= e serotonin reuptake inhibitors (SSRIs), tricyclic antidepressants (TCAs), = bupropion, triptans, dietary supplements (eg, St. John=E2=80=99s Wort, tryp= tophan), drugs that impair metabolism of serotonin (including monoamine oxi= dase inhibitors [MAOIs], which are contraindicated with FINTEPLA), dextrome= thorphan, lithium, tramadol, and antipsychotics with serotonergic agonist a= ctivity. Patients should be monitored for the emergence of signs and sympto= ms of serotonin syndrome, which include mental status changes (eg, agitatio= n, hallucinations, coma), autonomic instability (eg, tachycardia, labile bl= ood pressure, hyperthermia), neuromuscular signs (eg, hyperreflexia, incoor= dination), and/or gastrointestinal symptoms (eg, nausea, vomiting, diarrhea= ). If serotonin syndrome is suspected, treatment with FINTEPLA should be st= opped immediately and symptomatic treatment should be started.=C2=A0 Increase in Blood Pressure: FINTEPLA can cause an increase in blood pressur= e. Rare cases of significant elevation in blood pressure, including hyperte= nsive 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 closur= e 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 leas= t 10% and greater than placebo) were decreased appetite; somnolence, sedati= on, lethargy; diarrhea; constipation; abnormal echocardiogram; fatigue, mal= aise, asthenia; ataxia, balance disorder, gait disturbance; blood pressure = increased; drooling, salivary hypersecretion; pyrexia; upper respiratory tr= act infection; vomiting; decreased weight; fall; status epilepticus. The most common adverse reactions observed in the LGS study (incidence at l= east 10% and greater than placebo) were diarrhea; decreased appetite; fatig= ue; somnolence; vomiting. DRUG INTERACTIONS Strong CYP1A2, CYP2B6, or CYP3A Inducers: Coadministration with strong CYP1= A2, CYP2B6, or CYP3A inducers will decrease fenfluramine plasma concentrati= ons. If coadministration of a strong CYP1A2, CYP2B6, or CYP3A inducer with = FINTEPLA is necessary, monitor the patient for reduced efficacy and conside= r 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 administere= d prior to initiating the inducer. Strong CYP1A2 or CYP2D6 Inhibitors: Coadministration with strong CYP1A2 or = CYP2D6 inhibitors will increase fenfluramine plasma concentrations. If FINT= EPLA 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 gradua= l increase in the FINTEPLA dosage to the dose recommended without CYP1A2 or= CYP2D6 inhibitors. If FINTEPLA is coadministered with stiripentol and a st= rong CYP1A2 or CYP2D6 inhibitor, the maximum daily dosage of FINTEPLA is 17= mg.
