Pharmacokinetics/Pharmacodynamics of S1P Receptor Modulators: Implications for Clinical Care

Practical Aspects of Use: Monitoring and Titration

Assessments

• All agents: CBC, cardiac evaluation, liver function, medications, vaccinations

• Ophthalmic assessment: all agents (for ozanimod, only in patients with certain conditionse)

• CYP2C9 genotype: siponimod

Titrationd

Siponimod, ozanimod (per prescribing information)

First-Dose Monitoringd

Siponimod (patients with certain conditionsf),

fingolimod

S1P Receptor Modulators T1/2 Elimination Median Recovery Timeto Normal Lymphocyte Count

Fingolimod 6-9 da 1-2 months

Siponimod 30 h 10 days, but up to 3-4 weeks for some patients

Ozanimod CC112273b

21 h11 d 30 daysc

Ponesimod (investigational) 21-33 h 4 days

a Increased by 50% in patients with moderate to severe heart disease. b Major ozanimod active metabolite. c Ninety percent recovery to baseline lymphocyte count within 3 months. d Also on reinitiation following treatment interruption. e For ozanimod, requirement for pre-initiation assessment is specific to patients with a history of uveitis or macular edema. f Sinus bradycardia, Mobitz type I AV block, history of MI or HF.
