Mechanism of Action

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. Ponesimod binds with high affinity to S1P receptor 1 blocking the capacity of lymphocytes to egress from lymph nodes, reducing the number of lymphocytes in peripheral blood.

Ponvory Indications

Indications

Relapsing forms of multiple sclerosis (MS), to include clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease.

Ponvory Dosage and Administration

Prior to Treatment Evaluations

Complete Blood Count (CBC)

  • Obtain a recent CBC (i.e., within 6 months or after discontinuation of prior therapy) before initiating treatment with Ponvory.

Cardiac Evaluation 

  • Obtain an electrocardiogram (ECG) to determine whether preexisting conduction abnormalities are present. In patients with certain preexisting conditions, obtain advice from cardiologist and recommend first-dose monitoring. 

Liver Function

  • Obtain recent (i.e., within the last 6 months) transaminases (ALT and AST) and bilirubin levels.

Ophthalmic Evaluation

  • Obtain an evaluation of the fundus, including the macula.

Current or Prior Medications with Immune System Effects

  • Consider possible unintended additive immunosuppressive effects prior to initiation if concomitant use with anti-neoplastic, immunosuppressive, or immune-modulating therapies, or if there is a history of prior use of these drugs.

Vaccinations

  • Test patients for antibodies to varicella zoster virus (VZV) before initiating; VZV vaccination of antibody-negative patients is recommended prior to commencing treatment with Ponvory. If live attenuated vaccine immunizations are required, administer at least 1 month prior to initiation of Ponvory.

Adult

Swallow whole. Initially 2mg once daily on Days 1 and 2; 3mg once daily on Days 3 and 4; 4mg once daily on Days 5 and 6; 5mg once daily on Day 7; 6mg once daily on Day 8; 7mg once daily on Day 9; 8mg once daily on Day 10; 9mg once daily on Day 11; 10mg once daily on Days 12, 13, and 14. Maintenance: 20mg once daily on Day 15 and thereafter. First dose 4hr monitoring for bradycardia, other abnormalities: see full labeling. Re-initiation of therapy after interruption for ≥4 consecutive doses: start with Day 1 of titration regimen.

Adult

Treatment Initiation

  • Swallow whole.

  • Use 14-day starter pack when initiating treatment with Ponvory.

  • Initiate 2mg once daily on Days 1 and 2; 3mg once daily on Days 3 and 4; 4mg once daily on Days 5 and 6; 5mg once daily on Day 7; 6mg once daily on Day 8; 7mg once daily on Day 9; 8mg once daily on Day 10; 9mg once daily on Day 11; 10mg once daily on Days 12, 13, and 14.

Maintenance Dosage

  • After dose titration is complete, 20mg once daily on Day 15 and thereafter.

First-Dose Monitoring

  • Initiation of Ponvory treatment results in a decrease in heart rate, first-dose 4-hour monitoring is recommended for patients with sinus bradycardia (HR <55bpm), first- or second-degree (Mobitz type I) AV block, or a history of MI or HF occurring >6 months prior to treatment initiation and in stable condition. 

First 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 ECG prior to dosing and at the end of the 4-hour observation period.

Additional Monitoring After 4-Hour Monitoring

  • Continue monitoring until the abnormality resolves if any of the following is present (even in the absence of symptoms) after 4 hours:

    • the heart rate 4 hours post-dose is <45 beats per minute (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 ≥500msec, 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.

  • If treatment with Ponvory is considered in the following patients, advice from a cardiologist should be sought to determine the most appropriate monitoring strategy during treatment initiation:

    • With some preexisting heart and cerebrovascular conditions

    • With a prolonged QTc interval before dosing or during the 4-hour observations, or at additional risk for QT prolongation, or on concurrent therapy with QT prolonging drugs with a known risk of torsades de pointes

    • Receiving concurrent therapy with drugs that slow heart rate or AV conduction 

Reinitiation of Ponvory After Treatment Interruption

  • Interruption during treatment, especially during titration, is not recommended.

  • If less 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:

    • Reinitiate treatment with Day 1 of the titration regimen (new starter pack).

Children

Not established.

Warnings/Precautions

Infections

  • Obtain a recent CBC (i.e., within 6 months or after discontinuation of prior therapy) before initiating treatment with Ponvory. 

  • Consider interrupting treatment with Ponvory if a patient develops a serious infection. 

  • Do not initiate treatment in patients with active infection until resolved. Monitor for infection during and for 1 to 2 weeks after discontinuation.

  • Herpes Viral Infections: 

    • Test for antibodies to varicella zoster virus; if negative, consider immunization before starting Ponvory.

  • Cryptococcal Infections: 

    • Evaluate for signs or symptoms consistent with a cryptococcal infection and undergo prompt diagnostic evaluation and treatment.

    • Suspend treatment until a cryptococcal infection has been excluded. If cryptococcal meningitis is diagnosed, initiate appropriate treatment.

  • Progressive Multifocal Leukoencephalopathy (PML):

    • MRI findings may be apparent before clinical signs or symptoms. Monitoring with MRI for signs that may be consistent with PML may be useful.

    • Suspend Ponvory treatment if PML is suspected until PML has been excluded. Discontinue Ponvory treatment if PML is confirmed.

    • Monitor for the development of immune reconstitution syndrome (IRIS) and treat appropriately.
  • Prior and Concomitant Treatment with Antineoplastic, Immunosuppressive, or Immune-Modulating Therapies: 

    • Use caution when coadministering Ponvory with anti-neoplastic, immune-modulating, or immunosuppressive therapies (including corticosteroids) due to the risk of additive immune system effects.

  • Vaccinations:

    • Test for antibodies to VZV before initiating Ponvory in patients without a healthcare professional confirmed history of chickenpox or without documentation of a full course of vaccination against VZV. 

    • VZV vaccination for antibody-negative patients 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.

    • If live attenuated vaccine immunizations are required, give at least 1 month prior to starting Ponvoy. 

    • Avoid using live attenuated vaccines during and for 1 to 2 weeks after treatment with Ponvoy.

Bradyarrhythmia and Atrioventricular Conduction Delays

  • An up-titration scheme must be used to reach the maintenance dosage of Ponvory.

  • Reduction in heart rate 

    • Treatment initiation may result in a transient decrease in HR. 

  • Atrioventricular Conduction Delays 

    • Treatment initiation may result in transient AV conduction delays. 

    • 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.

    • If treatment with Ponvory is considered, seek advice from a cardiologist for individual with: significant QT prolongation (QTc >500msec); or atrial flutter/fibrillation or arrhythmia treated with Class Ia or Class III anti-arrhythmic drugs; or unstable ischemic heart disease, cardiac decompensated failure occurring more than 6 months prior to treatment initiation, history of cardiac arrest, cerebrovascular disease (TIA, stroke occurring more than 6 months prior to treatment initiation), or uncontrolled hypertension; or a history of Mobitz Type II second degree AV block or higher-grade AV block, sick-sinus syndrome, or sino-atrial heart block.

  • Treatment Initiation Recommendations

    • If patients is receiving a stable dose of beta-blocker, consider resting HR prior to starting Ponvory. If HR is >55bpm, Ponvory can be initiated. If HR is ≤55bpm, interrupt beta-blocker until baseline HR is >55bpm.

    • Do not initiate Ponvory treatment in patients receiving other drugs that decrease HR without consulting a cardiologist.

    • For all patients, obtain an ECG to determine whether preexisting conduction abnormalities are present. Dose titration is recommended for initiation to reduce cardiac effects.

    • First-dose monitoring is recommended for patients with sinus bradycardia, first-or second-degree [Mobitz type I] AV block, or a history of myocardial infarction or heart failure with onset more than 6 months prior to initiation.

    • Not recommended for patients with history of cardiac arrest, cerebrovascular disease (e.g., TIA, stroke occurring more than 6 months prior to treatment initiation), uncontrolled hypertension, or severe untreated sleep apnea. If treatment is considered, seek advice from a cardiologist.

    • Assess the overall benefit-risk of Ponvory use in patients with a history of recurrent syncope or symptomatic bradycardia. If treatment is considered, seek advice from a cardiologist.

    • Concomitant use with drugs that decrease HR (e.g., beta-blockers, non-dihydropyridine calcium channel blockers - diltiazem and verapamil, and other drugs that may decrease heart rate such as digoxin) may be associated with severe bradycardia and heart block. If treatment is considered, seek advice from a cardiologist.

Respiratory Effects

  • Use caution in patients with severe respiratory disease (i.e., pulmonary fibrosis, asthma, and chronic obstructive pulmonary disease). Perform spirometric evaluation of respiratory function during treatment if clinically indicated.

Liver Injury

  • Obtain transaminase and bilirubin levels prior to starting treatment with Ponvory (within 6 months). 

  • Evaluate hepatic enzymes in patients who develop symptoms that may indicate hepatic dysfunction, including unexplained nausea, vomiting, abdominal pain, fatigue, anorexia, rash with eosinophilia, or jaundice and/or dark urine. 

  • Discontinue Ponvory if significant liver injury is confirmed.

  • Not recommended to use in patients with moderate or severe hepatic impairment.

Increased Blood Pressure

  • Monitor blood pressure (BP) during treatment with Ponvory.

Cutaneous Malignancies

  • Periodic skin examination is recommended for all patients, particularly those with risk factors for skin cancer. 

  • Monitor for suspicious skin lesions. Promptly evaluate if a suspicious skin lesion is observed. Limit exposure to sunlight and ultraviolet light by wearing protective clothing and using a sunscreen with a high protection factor due to an increased risk for skin cancer.

  • Ponvory is not recommended in patients receiving phototherapy with UV-B radiation or PUVA-photochemotherapy.

Fetal Risk 

  • Advise females of reproductive potential to use effective contraception during and for 1 week after discontinuation.

Macular Edema

  • Perform an examination of the fundus, including the macula in all patients before starting treatment, and again at any time if a patient reports vision changes while on Ponvory therapy.  

  • Assess potential benefits and risks on whether or not to discontinue Ponvory therapy. Continuation of Ponvory therapy in patients with macular edema has not been evaluated.

  • Increased risk of macular edema in patients with a history of uveitis and patients with diabetes mellitus. Obtain regular follow-up examinations of the fundus in these patients.

Posterior Reversible Encephalopathy Syndrome (PRES)

  • Symptoms of PRES are usually reversible but may evolve into ischemic stroke or cerebral hemorrhage. Delay in diagnosis and treatment may lead to permanent neurological sequelae. 

  • Discontinue treatment if PRES is suspected.

Severe Increase in Disability After Stopping Ponvory

  • Monitor for development of severe increase in disability following discontinuation of Ponvory and begin appropriate treatment as needed.

Immune System Effects After Stopping Ponvory

  • When using immunosuppressants after stopping Ponvory therapy, apply caution 1 to 2 weeks after the last dose of Ponvory due to an additive effect on the immune system.

Pregnancy Considerations

Risk Summary

  • No adequate and well-controlled studies of Ponvory in pregnant women.

Ponvory Pharmacokinetics

Absorption

The time to reach maximum plasma concentration of ponesimod is 2–4 hours post-dose. The absolute oral bioavailability of a 10 mg dose is 84%. 

Distribution

Volme of distribution at steady state: 160 L. Ponesimod is highly bound to plasma proteins (>99%) and is mainly (78.5%) distributed in the plasma fraction of whole blood. 

Metabolism

Multiple CYP450 (CYP2J2, CYP3A4, CYP3A5, CYP4F3A, and CYP4F12) and non-CYP450 enzymes catalyze the oxidation of ponesimod to M12. Ponesimod also undergoes direct glucuronidation (mainly UGT1A1 and UGT2B7).

 

Elimination

After a single IV administration, the total clearance of ponesimod is 3.8 L/hour. The elimination half-life after oral administration is ~33 hours. Following a single oral administration of 14C-ponesimod, 57% to 80% of the dose was recovered in feces (16% as unchanged ponesimod), and 10% to 18% in urine (no unchanged ponesimod).

Ponvory Interactions

Interactions

Concomitant antineoplastic, immunosuppressant or immune-modulating therapies may increase risk of immunosuppression; use caution when switching from long-acting immunotherapies; caution for 1–2 weeks after discontinuing ponesimod. Initiation after treatment with alemtuzumab: not recommended. Concomitant QT prolonging drugs (eg, quinidine, procainamide, amiodarone, sotalol): risk of torsades de pointes; refer to cardiologist if treatment is considered. Concomitant β-blockers, digoxin, diltiazem, verapamil during initiation may be associated with severe bradycardia or heart block; refer to cardiologist if treatment is considered. Avoid live attenuated vaccines during and for 1–2 weeks after discontinuing ponesimod; may have suboptimal response. Antagonized by strong CYP3A4 and UGT1A1 inducers (eg, rifampin, phenytoin, carbamazepine): concomitant use not recommended. Concomitant phototherapy with UV-B radiation or PUVA-photochemotherapy: not recommended.

Ponvory Adverse Reactions

Adverse Reactions

Upper respiratory tract infection, hepatic transaminase elevation, hypertension, UTI, dyspnea, dizziness; macular edema, basal cell carcinoma/melanoma, decreased pulmonary function; PML, IRIS; rare: posterior reversible encephalopathy syndrome (discontinue if suspected).

Ponvory Clinical Trials

Clinical Trials

The approval was based on results from a phase 3 head-to-head, randomized trial of Ponvory vs teriflunomide. A total of 1133 patients with relapsing MS, were randomly assigned to either Ponvory 20mg once daily or teriflunomide 14mg once daily.

Results showed that the annualized relapse rate from baseline to Week 108 was reduced by 30.5% for the Ponvory group vs the teriflunomoide group, meeting the trial’s primary endpoint (P =.0003). Moreover, 70.7% of patients treated with Ponvory had no confirmed relapses compared with 60.6% of patients treated with teriflunomide.

Moreover, Ponvory showed superiority in reducing the number of new gadolinium-enhancing (GdE) T1 and T2 lesions compared with  teriflunomide by 58.5% and 55.7%, respectively (for both P <.0001).
