Objective:


To document efficacy, tolerability and safety of alternate (non-daily) dosing of fingolimod for MS.

Background:

Fingolimod 0.5 mg is approved for daily oral administration in MS. It has a half-life of 6 days and many clinicians utilize less frequent dosing (typically qod or tiw), especially for patients who develop liver enzyme elevations, severe lymphopenia or infections on standard daily dosing. Data on efficacy of alternate dosing is scarce.

Design/Methods:

 Multi-center retrospective chart and MRI review.

Results:

We identified 129 MS patients in 15 neurology clinics in the US, Spain, and Lebanon who received fingolimod at alternate doses (alt-dose) for >1 month. To date, chart review was completed for 42 patients (83% female, average age 43.0 +/-10.9 yrs, average disease duration 13.0 +/- 7.6 yrs).

All patients initially received daily fingolimod for (average) of 14.5 months (range 1.0 - 53.2 months) and later switched to alt-dose for (average) of 17.6 months (range 1.0 63.4 months). On daily dose, 5% of patients experienced ≥1 relapse and 31% had MRI activity, while on alt-dose, 12% experienced ≥1 relapse and 35% of patients had MRI activity.

Adverse events were recorded for 45% patients on daily dose and 12% of patients on alt-dose.

 62% [of the] patients remained on alt-dose at last follow-up, 4 (10%) went back to daily dose and 11 (26%) were switched to a different therapy. Updated data on full cohort will be presented.

Conclusions:

These observational data on MS patients treated with alternate dosing of fingolimod offers preliminary support for the use of this regimen, especially in patients who are not able to tolerate daily dosing. Alternate day dosing of fingolimod appears to be associated with less adverse effects (lower incidence of LFT [liver function test] abnormalities and severe lymphopenia) and is highly cost-effective. A prospective randomized non-inferiority trial of alternate day v. daily fingolimod 0.5 mg is warranted.
