Ozanimod
Brand names: Zeposia
Ozanimod is an oral sphingosine-1-phosphate (S1P) receptor modulator used to treat relapsing-remitting multiple sclerosis and moderately-to-severely active ulcerative colitis.
Adult dose
Dose adjustments
eMC §4.2: no dose adjustment is necessary for patients with renal impairment.
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
- Hypersensitivity to the active substance or to any of the excipients (eMC §4.3)
- Immunodeficient state predisposing to systemic opportunistic infections (eMC §4.3)
- Myocardial infarction, unstable angina, stroke, transient ischaemic attack, decompensated heart failure requiring hospitalisation, or NYHA Class III/IV heart failure in the last 6 months (eMC §4.3)
- History or presence of second-degree AV block Type II or third-degree AV block, or sick sinus syndrome, unless the patient has a functioning pacemaker (eMC §4.3; the US label adds sino-atrial block and severe untreated sleep apnoea)
- Severe active infections, active chronic infections such as hepatitis and tuberculosis; active malignancies; severe hepatic impairment (Child-Pugh C); pregnancy and women of childbearing potential not using effective contraception (eMC §4.3). The US label also contraindicates concomitant use of a monoamine oxidase inhibitor.
Side effects
- Nasopharyngitis - very common (12.3%); pharyngitis, viral respiratory tract infection, urinary tract infection, herpes zoster and herpes simplex - common; progressive multifocal leukoencephalopathy - rare
- Lymphopenia - very common
- Raised liver enzymes - alanine aminotransferase increased (5%), gamma-glutamyl transferase increased (5.4%) and blood bilirubin increased - common; liver injury - rare (post-marketing). Liver enzyme elevations were the most common cause of discontinuation (1.1% in MS studies)
- Bradycardia - common (transient on initiation, usually resolving by the end of the first week); hypertension and orthostatic hypotension - common
- Headache - common; peripheral oedema - common; macular oedema - uncommon (in patients with pre-existing risk factors); hypersensitivity including rash and urticaria - uncommon; abnormal pulmonary function tests - common
Interactions
- Beta-blockers and calcium-channel blockers (e.g. diltiazem, verapamil) - caution when initiating ozanimod because of additive heart-rate lowering; these agents may be started in patients already on stable ozanimod doses. Co-administration of ozanimod in patients on a beta-blocker combined with a calcium-channel blocker has not been studied (eMC §4.4/§4.5)
- Monoamine oxidase inhibitors - concomitant use is contraindicated in the US label (§4, §7)
- Anti-neoplastic, immune-modulating or non-corticosteroid immunosuppressive therapies - not studied in combination (except ciclosporin, which showed no pharmacokinetic interaction); use with caution because of the risk of additive immune effects during and in the weeks after such therapy (US label §7)
- Alemtuzumab - initiating ozanimod after alemtuzumab is not recommended because of the characteristics and duration of alemtuzumab's immunosuppressive effects (US label §7)
- Beta interferon or glatiramer acetate - ozanimod can generally be started immediately after discontinuation (US label §7). Live attenuated vaccines should be given at least 1 month before initiation (US label §2.1). The full eMC §4.5 interaction section was not captured in this bundle - clinician to review it in the SPC.
Clinical monograph
How it works
It selectively engages S1P1 and S1P5 receptors, trapping lymphocytes within lymph nodes and reducing the number of circulating lymphocytes available to enter the central nervous system.
Prescribing in practice
- Because it can cause bradycardia and AV conduction delay, a baseline ECG and cardiology review are needed in those with relevant cardiac disease, and dose initiation follows a gradual titration.
- Screening before starting must include full blood count, varicella-zoster immunity, liver function and an ophthalmological assessment for macular oedema risk.
- It is contraindicated with concomitant MAO inhibitors, and tyramine-rich foods should be limited because of an active metabolite with MAO-inhibitory properties.
Monitoring
Monitor full blood count, liver function, blood pressure and for signs of infection or macular oedema during treatment, with cardiac observation at initiation where indicated.
Counselling the patient
- Do not miss doses, as restarting may require repeating the gradual dose build-up.
- Report any visual disturbance, breathlessness, palpitations, or signs of infection promptly.
- Avoid live vaccines during and shortly after treatment, and tell your team if you plan to become pregnant.
Evidence & guidelines
The SUNBEAM and RADIANCE trials established its efficacy in relapsing MS, and it is recommended by NICE for relapsing-remitting disease and for ulcerative colitis.
