Warnings
• Infections: Fingolimod may increase the risk. Obtain a complete blood count (CBC) before initiating treatment. Monitor for infection during treatment and for 2 months after discontinuation. Do not start in patients with active infections. ( 5.2 ) • Progressive Multifocal Leukoencephalopathy (PML): Withhold fingolimod at the first sign or symptom suggestive of PML. ( 5.3 ) • Macular Edema : Increases the risk of macular edema. Obtain a baseline evaluation of the fundus, including the macula, near the start of treatment with fingolimod. Conduct an evaluation of the fundus, including the macula, 3 to 4 months after treatment start, periodically while on therapy and any time there is a change in vision. Consider discontinuing fingolimod if macular edema develops. Diabetes mellitus and uveitis increase the risk. ( 5.4 ) • Liver Injury : Obtain liver enzyme results before initiation and periodically during treatment. Closely monitor patients with severe hepatic impairment. Discontinue if there is evidence of liver injury without other cause. ( 5.5 , 8.6 , 12.3 ) • Posterior Reversible Encephalopathy Syndrome (PRES): If suspected, discontinue fingolimod. ( 5.6 ) • Respiratory Effects: Evaluate when clinically indicated. ( 5.7 ) • Fetal Risk: May cause fetal harm. Advise females of reproductive potential of the potential risk to a fetus and to use an effective method of contraception during treatment and for 2 months after stopping fingolimod. ( 5.8 , 8.1 , 8.3 ) • Severe Increase in Disability After Stopping Fingolimod : Monitor for development of severe increase in disability following discontinuation and begin appropriate treatment as needed. ( 5.9 ) • Tumefactive MS : Consider when severe MS relapse occurs during treatment or after discontinuation. Obtain imaging and begin treatment as needed. (5.10) • Increased Blood Pressure (BP): Monitor BP in adult and pediatric patients during treatment. ( 5.11 ) • Malignancies: Skin examination prior to or shortly after the start of treatment and periodically thereafter is recommended. Suspicious skin lesions should be evaluated. ( 5.12 ) 5.1 Bradyarrhythmia and Atrioventricular Blocks Because of a risk for bradyarrhythmia and AV blocks, patients should be monitored during fingolimod treatment initiation [ see Dosage and Administration ( 2.4 ) ]. Reduction in Heart Rate After the first dose of fingolimod, the heart rate decrease starts within an hour. On Day 1, the maximum decline in heart rate generally occurs within 6 hours and recovers, although not to baseline levels, by 8 to 10 hours postdose. Because of physiological diurnal variation, there is a second period of heart rate decrease within 24 hours after the first dose. In some patients, heart rate decrease during the second period is more pronounced than the decrease observed in the first 6 hours. Heart rates below 40 bpm in adults, and below 50 bpm in pediatric patients occurred rarely. In controlled clinical trials in adult patients, adverse reactions of symptomatic bradycardia following the first dose were reported in 0.6% of patients receiving fingolimod capsules 0.5 mg and in 0.1% of patients on placebo. Patients who experienced bradycardia were generally asymptomatic, but some patients experienced hypotension, dizziness, fatigue, palpitations, and/or chest pain that usually resolved within the first 24 hours on treatment. Patients with some preexisting conditions (e.g., ischemic heart disease, history of myocardial infarction, congestive heart failure, history of cardiac arrest, cerebrovascular disease, uncontrolled hypertension, history of symptomatic bradycardia, history of recurrent syncope, severe untreated sleep apnea, AV block, sinoatrial heart block) may poorly tolerate the fingolimod-induced bradycardia, or experience serious rhythm disturbances after the first dose of fingolimod. Prior to treatment with fingolimod, these patients should have a cardiac evaluation by a physician appropriately trained to conduct such evaluation, and if treated with fingolimod, should be monitored overnight with continuous ECG in a medical facility after the first dose. Since initiation of fingolimod treatment results in decreased heart rate and may prolong the QT interval, patients with a prolonged QTc interval (>450 msec adult and pediatric males, >470 msec adult females, or >460 msec pediatric females) before dosing or during 6-hour observation, or at additional risk for QT prolongation (e.g., hypokalemia, hypomagnesemia, congenital long-QT syndrome), or on concurrent therapy with QT prolonging drugs with a known risk of torsades de pointes (e.g., citalopram, chlorpromazine, haloperidol, methadone, erythromycin) should be monitored overnight with continuous ECG in a medical facility. Following the second dose, a further decrease in heart rate may occur when compared to the heart rate prior to the second dose, but this change is of a smaller magnitude than that observed following the first dose. With continued dosing, the heart rate returns to baseline within 1 month of chronic treatment. Clinical data indicate effects of fingolimod on heart rate are maximal after the first dose although milder effects on heart rate may persist for, on average, 2 to 4 weeks after initiation of therapy at which time heart rate generally returns to baseline. Physicians should continue to be alert to patient reports of cardiac symptoms. Atrioventricular Blocks Initiation of fingolimod treatment has resulted in transient AV conduction delays. In controlled clinical trials in adult patients, first-degree AV block after the first dose occurred in 4.7% of patients receiving fingolimod and 1.6% of patients on placebo. In a study of 697 patients with available 24-hour Holter monitoring data after their first dose (N=351 receiving fingolimod and N=346 on placebo), second-degree AV blocks (Mobitz Types I [Wenckebach] or 2:1 AV blocks) occurred in 4% (N=14) of patients receiving fingolimod and 2% (N=7) of patients on placebo. Of the 14 patients receiving fingolimod, 7 patients had 2:1 AV block (5 patients within the first 6 hours postdose and 2 patients after 6 hours postdose). All second-degree AV blocks on placebo were Mobitz Type I and occurred after the first 12 hours postdose. The conduction abnormalities were usually transient and asymptomatic, and resolved within the first 24 hours on treatment, but they occasionally required treatment with atropine or isoproterenol. Postmarketing Experience In the postmarketing setting, third-degree AV block and AV block with junctional escape have been observed during the first-dose 6-hour observation period with fingolimod. Isolated delayed onset events, including transient asystole and unexplained death, have occurred within 24 hours of the first dose. These events were confounded by concomitant medications and/or preexisting disease, and the relationship to fingolimod is uncertain. Cases of syncope were also reported after the first dose of fingolimod capsules. 5.2 Infections Risk of Infections Fingolimod causes a dose-dependent reduction in peripheral lymphocyte count to 20% to 30% of baseline values because of reversible sequestration of lymphocytes in lymphoid tissues. Fingolimod may therefore increase the risk of infections, some serious in nature [ see Clinical Pharmacology ( 12.2 ) ] . Life-threatening and fatal infections have occurred in association with fingolimod. Before initiating treatment with fingolimod, a recent CBC (i.e., within 6 months or after discontinuation of prior therapy) should be available. Consider suspending treatment with fingolimod if a patient develops a serious infection, and reassess the benefits and risks prior to reinitiation of therapy. Because the elimination of fingolimod after discontinuation may take up to 2 months, continue monitoring for infections throughout this period. Instruct patients receiving fingolimod to report symptoms of infections to a physician. Patients with active acute or chronic infections should not start treatment until the infection(s) is resolved. In MS placebo-controlled trials in adult patients, the overall rate of infections (72%) with fingolimod was similar to placebo. However, bronchitis, herpes zoster, influenza, sinusitis, and pneumonia were more common in fingolimod -treated patients. Serious infections occurred at a rate of 2.3% in the fingolimod group versus 1.6% in the placebo group. In the postmarketing setting, serious infections with opportunistic pathogens, including viruses (e.g., John Cunningham virus [JCV], herpes simplex viruses 1 and 2, varicella zoster virus), fungi (e.g., cryptococci), and bacteria (e.g., atypical mycobacteria) have been reported with fingolimod. Patients with symptoms and signs consistent with any of these infections should undergo prompt diagnostic evaluation and appropriate treatment. Herpes Viral Infections In placebo-controlled trials in adult patients, the rate of herpetic infections was 9% in patients receiving fingolimod capsule 0.5 mg and 7% on placebo. Two patients died of herpetic infections during controlled trials. One death was due to disseminated primary herpes zoster and the other was to herpes simplex encephalitis. In both cases, the patients were taking a 1.25 mg dose of fingolimod (higher than the recommended 0.5 mg dose) and had received high-dose corticosteroid therapy to treat suspected MS relapses. Serious, life-threatening events of disseminated varicella zoster and herpes simplex infections, including cases of encephalitis and multiorgan failure, have occurred with fingolimod in the postmarketing setting. Include disseminated herpetic infections in the differential diagnosis of patients who are receiving fingolimod and present with an atypical MS relapse or multiorgan failure. Cases of Kaposi's sarcoma have been reported in the postmarketing setting. Kaposi's sarcoma is an angioproliferative disorder that is associated with infection with human herpes virus 8 (HHV-8). Patients with symptoms or signs consistent with Kaposi's sarcoma should be referred for prompt diagnostic evaluation and management. Cryptococcal Infections Cryptococcal infections, including cases of fatal cryptococcal meningitis and disseminated cryptococcal infections, have been reported with fingolimod in the postmarketing setting. Cryptococcal infections have generally occurred after approximately 2 years of fingolimod treatment, but may occur earlier. The relationship between the risk of cryptococcal infection and the duration of treatment is unknown. Patients with symptoms and signs consistent with a cryptococcal infection should undergo prompt diagnostic evaluation and treatment. Prior and Concomitant Treatment with Antineoplastic, Immunosuppressive, or Immune-Modulating Therapies In clinical studies, patients who received fingolimod did not receive concomitant treatment with antineoplastic, noncorticosteroid immunosuppressive, or immune-modulating therapies used for treatment of MS. Concomitant use of fingolimod with any of these therapies, and also with corticosteroids, would be expected to increase the risk of immunosuppression [see Drug Interactions ( 7.4 )] . When switching to fingolimod from immune-modulating or immunosuppressive medications, consider the duration of their effects and their mode of action to avoid unintended additive immunosuppressive effects. Varicella Zoster Virus Antibody Testing/Vaccination Patients without a healthcare professional confirmed history of chickenpox or without documentation of a full course of vaccination against VZV should be tested for antibodies to VZV before initiating fingolimod. VZV vaccination of antibody-negative patients is recommended prior to commencing treatment with fingolimod, following which initiation of treatment with fingolimod should be postponed for 1 month to allow the full effect of vaccination to occur [see Drug Interactions ( 7.3 ), Use in Specific Populations ( 8.4 )].

Adults In clinical trials (Studies 1, 2, and 3), a total of 1,212 patients with relapsing forms of multiple sclerosis received fingolimod capsule 0.5 mg. This included 783 patients who received fingolimod capsule 0.5 mg in the 2-year placebo-controlled trials (Studies 1 and 3) and 429 patients who received fingolimod capsule 0.5 mg in the 1-year active-controlled trial (Study 2). The overall exposure in the controlled trials was equivalent to 1,716 person-years . Approximately 1,000 patients received at least 2 years of treatment with fingolimod capsule 0.5 mg. In all clinical studies, including uncontrolled extension studies, the exposure to fingolimod capsule 0.5 mg was approximately 4,119 person-years. In placebo-controlled trials, the most frequent adverse reactions (incidence ≥10% and greater than placebo) for fingolimod capsule 0.5 mg were headache, liver transaminase elevation, diarrhea, cough, influenza, sinusitis, back pain, abdominal pain, and pain in extremity. Adverse events that led to treatment discontinuation and occurred in more than 1% of patients taking fingolimod capsule 0.5 mg, were serum transaminase elevations (4.7% compared to 1% on placebo) and basal cell carcinoma (1% compared to 0.5% on placebo). Table 1 lists adverse reactions in clinical studies in adults that occurred in ≥ 1% of fingolimod-treated patients and ≥ 1% higher rate than for placebo.

Adverse reactions of seizure, dizziness, pneumonia, eczema, and pruritus were also reported in Studies 1 and 3, but did not meet the reporting rate criteria for inclusion in Table 1 (difference was less than 1%). Adverse reactions with fingolimod capsule 0.5 mg in Study 2, the 1-year active-controlled (versus interferon beta-1a) study were generally similar to those in Studies 1 and 3. Vascular Events Vascular events, including ischemic and hemorrhagic strokes, and peripheral arterial occlusive disease were reported in premarketing clinical trials in patients who received fingolimod doses (1.25 mg to 5 mg) higher than recommended for use in MS. Similar events have been reported with fingolimod in the postmarketing setting although a causal relationship has not been established. Seizure Cases of seizures, including status epilepticus, have been reported with the use of fingolimod in clinical trials and in the postmarketing setting in adults [see Adverse Reactions ( 6.2 )]. In adult clinical trials, the rate of seizures was 0.9% in fingolimod-treated patients and 0.3% in placebo-treated patients. It is unknown whether these events were related to the effects of multiple sclerosis alone, to fingolimod, or to a combination of both. Pediatric Patients 10 Years of Age and Older In the controlled pediatric trial (Study 4), the safety profile in pediatric patients receiving fingolimod 0.25 mg or 0.5 mg daily was similar to that seen in adult patients. In the pediatric study, cases of seizures were reported in 5.6% of fingolimod-treated patients and 0.9% of interferon beta-1a-treated patients [see Use in Specific Populations (8.4)]. 6.2 Postmarketing Experience The following adverse reactions have been identified during postapproval use of fingolimod. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Blood and Lymphatic System Disorders: Hemolytic anemia and thrombocytopenia Hepatobiliary Disorders: Liver injury [see Warnings and Precautions ( 5.5 )] Infections: Infections, including cryptococcal infections [see Warnings and Precautions ( 5.2 )], human papilloma virus (HPV) infection, including papilloma, dysplasia, warts and HPV-related cancer [see Warnings and Precautions ( 5.2 )], progressive multifocal leukoencephalopathy [see Warnings and Precautions ( 5.3 )] Musculoskeletal and Connective Tissue Disorders: Arthralgia, myalgia Nervous System Disorders : Posterior reversible encephalopathy syndrome [see Warnings and Precautions ( 5.6 )], seizures, including status epilepticus [see Adverse Reactions ( 6.1 )] Neoplasms, Benign, Malignant, and Unspecified (including cysts and polyps): Melanoma, Merkel cell carcinoma, cutaneous T-cell lymphoma (including mycosis fungoides), Kaposi’s sarcoma, squamous cell carcinoma [see Warnings and Precautions ( 5.12 )] Skin and Subcutaneous Tissue Disorders: Hypersensitivity [see Warnings and Precautions ( 5.14 )]
