Fingolimod
Brand names: Gilenya
Fingolimod is an oral sphingosine-1-phosphate receptor modulator used as a disease-modifying therapy for highly active relapsing-remitting multiple sclerosis.
Adult dose
Dose adjustments
Fingolimod was not studied in patients with renal impairment in the multiple sclerosis pivotal studies; based on clinical pharmacology studies, no dose adjustments are needed in patients with mild to severe renal impairment (eMC §4.2).
Dose auto-extracted from UK Summary of Product Characteristics (SPC) via the eMC; US FDA prescribing information (openFDA / DailyMed) — cross-check; US labelling may differ from UK — not yet clinician-verified. Always confirm against the product SmPC and your local formulary before prescribing.
Contraindications
- Immunodeficiency syndrome
- Patients at increased risk of opportunistic infections, including immunocompromised patients (those currently receiving immunosuppressive therapies or immunocompromised by prior therapies)
- Suspected or confirmed progressive multifocal leukoencephalopathy (PML)
- Severe active infections, and active chronic infections (hepatitis, tuberculosis)
- Active malignancies
- Severe liver impairment (Child-Pugh class C)
- Myocardial infarction, unstable angina pectoris, stroke/TIA, decompensated heart failure requiring inpatient treatment, or NYHA class III/IV heart failure in the previous 6 months
- Severe cardiac arrhythmias requiring anti-arrhythmic treatment with class Ia or class III anti-arrhythmic medicines
- Second-degree Mobitz type II or third-degree AV block, or sick-sinus syndrome, in patients without a pacemaker
- Baseline QTc interval of 500 msec or more
- Pregnancy, and women of childbearing potential not using effective contraception
- Hypersensitivity to the active substance or to any of the excipients
Side effects
- Headache (24.5%), hepatic enzyme increased — ALT, GGT, AST (15.2%), diarrhoea (12.6%) and back pain (10.0%) — all very common at the 0.5 mg dose
- Infections: influenza (11.4%) and sinusitis (10.9%) very common; cough (12.3%) very common and bronchitis, herpes viral infections and tinea versicolor common; pneumonia uncommon; progressive multifocal leukoencephalopathy and cryptococcal infections reported (frequency not known)
- Bradycardia and atrioventricular block (common) — first-dose monitoring is required; hypertension (common)
- Lymphopenia and leucopenia (common), thrombocytopenia (uncommon); macular oedema and blurred vision; seizure (uncommon) and posterior reversible encephalopathy syndrome (rare)
- Malignancies: basal cell carcinoma (common), malignant melanoma (uncommon), lymphoma and squamous cell carcinoma (rare); also acute hepatic failure and severe exacerbation of disease after fingolimod discontinuation (frequency not known)
Interactions
- QT-prolonging drugs with a known risk of torsades de pointes (e.g. citalopram, chlorpromazine, haloperidol, methadone, erythromycin) — patients should be monitored overnight with continuous ECG in a medical facility, since fingolimod decreases heart rate and may prolong the QT interval (US labelling §7.1)
- Systemic ketoconazole — blood levels of fingolimod and fingolimod-phosphate are increased 1.7-fold; monitor closely as the risk of adverse reactions is increased (US labelling §7.2)
- Live attenuated vaccines — avoid during treatment and for 2 months after stopping; fingolimod reduces the immune response to vaccination and vaccination may be less effective during and for up to 2 months after discontinuation (US labelling §7.3)
- Drugs that slow heart rate or atrioventricular conduction — determine whether the patient is taking any before starting treatment, as they affect first-dose monitoring requirements (US labelling §2.1, §2.4)
- Antineoplastic, immunosuppressive or immune-modulating therapies (current or prior) — consider possible unintended additive immunosuppressive effects before initiating fingolimod (US labelling §2.1)
- The eMC §4.5 interaction section was not captured in this bundle — clinician to review it in the SPC
Clinical monograph
How it works
It is phosphorylated in vivo and sequesters lymphocytes within lymph nodes by down-regulating S1P receptors, reducing infiltration of autoreactive T cells into the central nervous system.
Prescribing in practice
- First-dose bradycardia and atrioventricular block can occur, so initiation requires baseline ECG and a period of monitored cardiac observation after the first dose.
- Screen for varicella-zoster immunity, baseline liver function and a recent dermatological and macular assessment before starting.
- Contraindicated in significant cardiac disease, recent cardiovascular events and during pregnancy because of teratogenicity.
Monitoring
Monitor full blood count, liver function, blood pressure, ophthalmic review for macular oedema and remain alert for infection throughout treatment.
Counselling the patient
- Report any breathlessness, dizziness or palpitations, particularly in the first hours after the initial dose.
- Use effective contraception during and for a defined period after stopping, and tell your team promptly if pregnancy is possible.
- Seek urgent advice for fever, persistent infection or visual disturbance.
Evidence & guidelines
NICE recommends fingolimod within its marketing authorisation for highly active relapsing-remitting multiple sclerosis.
