DOSAGE AND ADMINISTRATION Assessments are required prior to initiating PONVORY ( 2.1 ) Titration is required for treatment initiation ( 2.2 ) The recommended maintenance dosage is 20 mg taken orally once daily ( 2.2 ) First-dose monitoring is recommended for patients with sinus bradycardia, first- or second-degree [Mobitz type I] atrioventricular (AV) block, or a history of myocardial infarction or heart failure ( 2.3 ) 2.1 Assessments Prior to First Dose of PONVORY Before initiation of treatment with PONVORY, assess the following: Cardiac Evaluation Obtain an electrocardiogram (ECG) to determine whether preexisting conduction abnormalities are present. In patients with certain preexisting conditions, advice from a cardiologist should be sought and first-dose monitoring is recommended [see Dosage and Administration ( 2.3 ) and Warnings and Precautions ( 5.2 )] . Complete Blood Count Obtain a recent (i.e., within the last 6 months or after discontinuation of prior MS therapy) complete blood count (CBC), including lymphocyte count [see Warnings and Precautions ( 5.1 )] . Determine whether patients are taking drugs that could slow heart rate or atrioventricular (AV) conduction [see Warnings and Precautions ( 5.2 ) and Drug Interactions ( 7.2 , 7.3 )] . Liver Function Tests Obtain recent (i.e., within the last 6 months) transaminase and bilirubin levels [see Warnings and Precautions ( 5.4 )] . Ophthalmic Evaluation Obtain a baseline evaluation of the fundus, including the macula, near the start of treatment with PONVORY [see Warnings and Precautions ( 5.8 )] . Skin Examination Obtain a baseline skin examination prior to or shortly after initiation of PONVORY. If a suspicious skin lesion is observed, it should be promptly evaluated [see Warnings and Precautions ( 5.6 )] . Current or Prior Medications with Immune System Effects If patients are taking anti-neoplastic, immunosuppressive, or immune-modulating therapies, or if there is a history of prior use of these drugs, consider possible unintended additive immunosuppressive effects before initiating treatment with PONVORY [see Warnings and Precautions ( 5.1 , 5.10 ) and Drug Interactions ( 7.1 )] . Vaccinations Test patients for antibodies to varicella zoster virus (VZV) before initiating PONVORY; VZV vaccination of antibody-negative patients is recommended prior to commencing treatment with PONVORY [see Warnings and Precautions ( 5.1 )] . If live attenuated vaccine immunizations are required, administer at least 1 month prior to initiation of PONVORY. 2.2 Recommended Dosage Maintenance Dosage After dose titration is complete (see Treatment Initiation) , the recommended maintenance dosage of PONVORY is 20 mg taken orally once daily starting on Day 15. Administer PONVORY orally once daily. Swallow the tablet whole. PONVORY can be taken with or without food. Treatment Initiation A starter pack must be used for patients initiating treatment with PONVORY [see How Supplied/Storage and Handling ( 16.1 )] . Initiate PONVORY treatment with a 14-day titration; start with one 2 mg tablet orally once daily and progress with the titration schedule as shown in Table 1 [see Warnings and Precautions ( 5.2 )] . Table 1: Dose Titration Regimen Titration Day Daily Dose Days 1 and 2 2 mg Days 3 and 4 3 mg Days 5 and 6 4 mg Day 7 5 mg Day 8 6 mg Day 9 7 mg Day 10 8 mg Day 11 9 mg Days 12, 13, and 14 10 mg Maintenance Daily Dose Day 15 and thereafter 20 mg If dose titration is interrupted, missed dose instructions must be followed [see Dosage and Administration ( 2.4 )] . 2.3 First Dose Monitoring in Patients with Certain Preexisting Cardiac Conditions Because initiation of PONVORY treatment results in a decrease in heart rate, first-dose 4-hour monitoring is recommended for patients with sinus bradycardia [heart rate less than 55 beats per minute (bpm)], first- or second-degree [Mobitz type I] AV block, or a history of myocardial infarction or heart failure occurring more than 6 months prior to treatment initiation and in stable condition [see Warnings and Precautions ( 5.2 ) and Clinical Pharmacology ( 12.2 )] . First Dose 4-Hour Monitoring Administer the first dose of PONVORY in a setting where resources to appropriately manage symptomatic bradycardia are available. Monitor patients for 4 hours after the first dose for signs and symptoms of bradycardia with a minimum of hourly pulse and blood pressure measurements. Obtain an ECG in these patients prior to dosing and at the end of the 4-hour observation period. Additional Monitoring After 4-Hour Monitoring If any of the following abnormalities are present after 4 hours (even in the absence of symptoms), continue monitoring until the abnormality resolves: The heart rate 4 hours post-dose is less than 45 bpm The heart rate 4 hours post-dose is at the lowest value post-dose, suggesting that the maximum pharmacodynamic effect on the heart may not have occurred The ECG 4 hours post-dose shows new onset second-degree or higher AV block If post-dose symptomatic bradycardia, bradyarrhythmia, or conduction related symptoms occur, or if ECG 4 hours post-dose shows new onset second degree or higher AV block or QTc greater than or equal to 500 msec, initiate appropriate management, begin continuous ECG monitoring, and continue monitoring until the symptoms have resolved if no pharmacological treatment is required. If pharmacological treatment is required, continue monitoring overnight and repeat 4-hour monitoring after the second dose. Advice from a cardiologist should be sought to determine the most appropriate monitoring strategy (which may include overnight monitoring) during treatment initiation, if treatment with PONVORY is considered in patients: With some preexisting heart and cerebrovascular conditions [see Warnings and Precautions ( 5.2 )] With a prolonged QTc interval before dosing or during the 4-hour observation, or at additional risk for QT prolongation, or on concurrent therapy with QT prolonging drugs with a known risk of torsades de pointes [see Warnings and Precautions ( 5.2 ) and Drug Interactions ( 7.2 )] Receiving concurrent therapy with drugs that slow heart rate or AV conduction [see Drug Interactions ( 7.2 , 7.3 )] 2.4 Reinitiation of PONVORY After Treatment Interruption Interruption during treatment, especially during titration, is not recommended; however: If fewer than 4 consecutive doses are missed: during titration: resume treatment with the first missed titration dose and resume the titration schedule at that dose and titration day. during maintenance: resume treatment with the maintenance dosage. If 4 or more consecutive doses are missed during titration or maintenance: treatment should be reinitiated with Day 1 of the titration regimen (new starter pack). If treatment needs to be reinitiated with Day 1 of the titration regimen (new starter pack), complete first-dose monitoring in patients for whom it is recommended [see Dosage and Administration ( 2.3 )] .

WARNINGS AND PRECAUTIONS Infections : PONVORY may increase the risk of infections. Obtain a complete blood count (CBC) before initiating treatment. Monitor for infection during treatment and for 1-2 weeks after discontinuation. Do not start PONVORY in patients with active infection. ( 5.1 ) Bradyarrhythmia and Atrioventricular Conduction Delays : PONVORY may result in a transient decrease in heart rate; titration is required for treatment initiation. Check an electrocardiogram (ECG) to assess for preexisting cardiac conduction abnormalities before starting PONVORY. Consider cardiology consultation for conduction abnormalities or concomitant use with other drugs that decrease heart rate. ( 5.2 , 7.2 , 7.3 ) Respiratory Effects : May cause a decline in pulmonary function. Assess pulmonary function (e.g., spirometry) if clinically indicated. ( 5.3 ) Liver Injury : Discontinue if significant liver injury is confirmed. Obtain liver function tests before initiating PONVORY. ( 5.4 ) Increased Blood Pressure (BP) : Monitor BP during treatment. ( 5.5 ) Cutaneous Malignancies : Skin examination prior to or shortly after the start of treatment and periodically is recommended. Suspicious skin lesions should be evaluated. ( 5.6 ) Fetal Risk : Women of childbearing potential should use effective contraception during and for 1 week after stopping PONVORY. ( 5.7 ) Macular Edema : Increases the risk of macular edema. Obtain a baseline evaluation of the fundus, including the macula, near the start of treatment with PONVORY. Conduct an evaluation of the fundus, including the macula, periodically while on therapy and any time there is a change in vision. Consider discontinuing PONVORY if macular edema develops. Diabetes mellitus and uveitis increase the risk. ( 5.8 ) 5.1 Infections Risk of Infections PONVORY causes a dose-dependent reduction in peripheral lymphocyte count to 30-40% of baseline values because of reversible sequestration of lymphocytes in lymphoid tissues [see Clinical Pharmacology ( 12.2 )] . PONVORY may therefore increase the susceptibility to infections. Life-threatening and rare fatal infections have been reported in association with other sphingosine 1-phosphate (S1P) receptor modulators. In Study 1 [see Clinical Studies ( 14 )] , the overall rate of infections was comparable between the PONVORY-treated patients and those receiving teriflunomide 14 mg (54.2% vs 52.1%, respectively). PONVORY increased the risk of upper respiratory tract infections. Serious or severe infections occurred in 1.6% of PONVORY-treated patients compared to 0.9% of patients receiving teriflunomide 14 mg. Before initiating treatment with PONVORY, results from a recent (i.e., within 6 months or after discontinuation of prior therapy) complete blood count including lymphocyte count should be reviewed. Initiation of treatment with PONVORY should be delayed in patients with active infection until resolution. Lymphocyte counts returned to the normal range in 90% of patients within 1 week of stopping therapy in modeling studies [see Clinical Pharmacology ( 12.2 )] . In Study 1, peripheral lymphocyte counts returned to normal range within 2 weeks after discontinuation of PONVORY, which was the first timepoint evaluated. Because residual pharmacodynamic effects, such as lowering effects on peripheral lymphocyte count, may persist for 1 to 2 weeks after discontinuation of PONVORY, vigilance for infection should be continued for 1 to 2 weeks after PONVORY is discontinued [see Warnings and Precautions ( 5.12 )] . In Study 1, the proportion of patients who experienced lymphocyte counts less than 0.2x10 9 /L was 3.2%. Effective diagnostic and therapeutic strategies should be employed in patients with symptoms of infection while on therapy. Consider interruption of treatment with PONVORY if a patient develops a serious infection. Herpes Viral Infections Cases of herpes viral infection have been reported in the development program of PONVORY; herpes simplex encephalitis and varicella zoster meningitis have been reported with other S1P receptor modulators. In Study 1, the rate of herpetic infections was 4.8% for both PONVORY-treated patients and those receiving teriflunomide 14 mg. Patients without a healthcare professional confirmed history of varicella (chickenpox) or without documentation of a full course of vaccination against VZV should be tested for antibodies to VZV before initiating PONVORY (see Vaccinations ) . Cryptococcal Infections Cases of fatal cryptococcal meningitis (CM) and disseminated cryptococcal infections have been reported with other S1P receptor modulators. Physicians should be vigilant for clinical symptoms or signs of CM. Patients with symptoms or signs consistent with a cryptococcal infection should undergo prompt diagnostic evaluation and treatment. PONVORY treatment should be suspended until a cryptococcal infection has been excluded. If CM is diagnosed, appropriate treatment should be initiated. Progressive Multifocal Leukoencephalopathy Progressive multifocal leukoencephalopathy (PML) is an opportunistic viral infection of the brain caused by the JC virus (JCV) that typically only occurs in patients who are immunocompromised, and that usually leads to death or severe disability. Typical symptoms associated with PML are diverse, progress over days to weeks, and include progressive weakness on one side of the body or clumsiness of limbs, disturbance of vision, and changes in thinking, memory, and orientation leading to confusion and personality changes. PML has been reported in patients treated with S1P receptor modulators and other multiple sclerosis (MS) therapies and has been associated with some risk factors (e.g., immunocompromised patients, polytherapy with immunosuppressants, duration of use). Longer treatment duration increases the risk of PML in patients treated with S1P receptor modulators, and the majority of PML cases have occurred in patients treated with S1P receptor modulators for at least 18 months. Physicians should be vigilant for clinical symptoms or magnetic resonance imaging (MRI) findings that may be suggestive of PML. MRI findings may be apparent before clinical signs or symptoms. If PML is suspected, treatment with PONVORY should be suspended until PML has been excluded. If PML is confirmed, treatment with PONVORY should be discontinued. Immune reconstitution inflammatory syndrome (IRIS) has been reported in patients treated with S1P receptor modulators who developed PML and subsequently discontinued treatment. IRIS presents as a clinical decline in the patient’s condition that may be rapid, can lead to serious neurological complications or death, and is often associated with characteristic changes on MRI. The time to onset of IRIS in patients with PML was generally within a few months after S1P receptor modulator discontinuation. Monitoring for development of IRIS and appropriate treatment of the associated inflammation should be undertaken. Prior and Concomitant Treatment with Anti-neoplastic, Immune-Modulating, or Immunosuppressive Therapies Anti-neoplastic, immune-modulating, or immunosuppressive therapies (including corticosteroids) should be coadministered with caution because of the risk of additive immune system effects [see Drug Interactions ( 7.1 )] . Vaccinations 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 PONVORY treatment. A full course of vaccination for antibody-negative patients with varicella vaccine is recommended prior to commencing treatment with PONVORY, following which initiation of treatment with PONVORY should be postponed for 4 weeks to allow the full effect of vaccination to occur. No clinical data are available on the efficacy and safety of vaccinations in patients taking PONVORY. Vaccinations may be less effective if administered during PONVORY treatment. I

Mechanism of Action Ponesimod is a sphingosine 1-phosphate (S1P) receptor 1 modulator that binds with high affinity to S1P receptor 1. Ponesimod blocks the capacity of lymphocytes to egress from lymph nodes, reducing the number of lymphocytes in peripheral blood. The mechanism by which ponesimod exerts therapeutic effects in multiple sclerosis is unknown, but may involve reduction of lymphocyte migration into the central nervous system.
