A total of 1438 MS patients have received PONVORY at doses of at least 2 mg daily. These patients were included in Study 1 (2-year active-controlled versus teriflunomide 14 mg) [see Clinical Studies (14) ] and in a Phase 2 (6-month placebo-controlled) study in patients with MS and the uncontrolled extension studies. In Study 1, 82% of PONVORY-treated patients completed 2 years of study treatment, compared to 82.2% of patients receiving teriflunomide 14 mg. Adverse events led to discontinuation of treatment in 8.7% of PONVORY-treated patients, compared to 6% of patients receiving teriflunomide 14 mg. The most common adverse reactions (incidence at least 10%) in PONVORY-treated patients in Study 1 were upper respiratory tract infection, hepatic transaminase elevation, and hypertension. Table 3 lists adverse reactions that occurred in at least 2% of PONVORY-treated patients and at a higher rate than in patients receiving teriflunomide 14 mg. Table 3: Adverse Reactions Reported in Study 1 Occurring in at Least 2% of PONVORY-Treated Patients and at a Higher Rate Than in Patients Receiving Teriflunomide 14 mg Adverse Reaction PONVORY Teriflunomide 14 mg N=565 (%) N=566 (%) Upper respiratory infection Includes the following terms: nasopharyngitis, upper respiratory tract infection, pharyngitis, respiratory tract infection, bronchitis, respiratory tract infection viral, viral upper respiratory tract infection, tracheitis, and laryngitis. 37 34 Hepatic transaminase elevation Includes the following terms: alanine aminotransferase increased, aspartate aminotransferase increased, hepatic enzyme increased, and transaminases increased. 23 12 Hypertension Includes the following terms: hypertension, hypertensive crisis, blood pressure increased, blood pressure systolic increased, and blood pressure diastolic increased. 10 9 Urinary tract infection 6 5 Dyspnea 5 1 Dizziness 5 3 Cough 4 2 Pain in extremity 4 3 Somnolence 3 2 Pyrexia 2 1 C-reactive protein increased 2 1 Hypercholesterolemia 2 1 Vertigo 2 1 In Study 1, the following adverse reactions occurred in less than 2% of PONVORY-treated patients, but at a rate at least 1% higher than in patients receiving teriflunomide 14 mg: viral infection, herpes zoster, hyperkalemia, lymphopenia [see Warnings and Precautions (5.1) , and macular edema [see Warnings and Precautions (5.8) ]. Adverse reactions in patients treated with PONVORY in an additional 6-month placebo-controlled study were generally similar to those in Study 1. The following additional adverse reactions occurred in at least 2% of PONVORY 20 mg-treated patients and at a higher rate than in patients receiving placebo (but did not meet the reporting rate criteria for inclusion in Study 1): rhinitis, fatigue, chest discomfort, peripheral edema, joint swelling, blood cholesterol increased, migraine, insomnia, depression, dyspepsia, dry mouth, bradycardia, back pain, and sinusitis. Additionally, in uncontrolled extension trials, the adverse reaction of pneumonia was reported. Seizures In Study 1, cases of seizures were reported in 1.4% of PONVORY-treated patients, compared to 0.2% in patients receiving teriflunomide 14 mg. It is not known whether these events were related to the effects of MS, to PONVORY, or to a combination of both. Respiratory Effects In Study 1, dose-dependent reductions in forced expiratory volume over 1 second (FEV 1 ) were observed in patients treated with PONVORY [see Warnings and Precautions (5.3) ] . Malignancies In Study 1, two cases of basal cell carcinoma (0.4%) were reported in PONVORY-treated patients, compared to one case of basal cell carcinoma (0.2%) in patients receiving teriflunomide 14 mg, and a case of malignant melanoma was reported in a PONVORY-treated patient. An increased risk of cutaneous malignancies has been reported in association with other S1P receptor modulators, including PONVORY [see Warnings and Precautions (5.6) ] .

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
