Description
Summary:Dimethylfumarate (DMF) is approved for the treatment of moderate to severe psoriasis. In clinical practice, DMF tolerability is improved by slowly up-titrating the dose. Time-to-onset of gastrointestinal complaints (a common adverse event [AE]) is ∼4 weeks, coinciding with the increase in dose to one 120-mg tablet. The average DMF dose during maintenance treatment is also often lower than the maximum indicated dose of 720 mg/day. Here, a simplified dose-escalation strategy is described, where twice-daily DMF was up-titrated to a maximum of 720 mg/day (if required) in week 7. Ten patients received DMF according to the new scheme (maximum dose: 720 mg/day [n = 5], 480 mg/day [n = 3; escalation halted early due to good efficacy], and ≤240 mg/day [n = 2] by week 12). Mean Psoriasis Area Severity Index (PASI) decreased from 7.2 to 0.9 between weeks 0 and 24. Absolute Psoriasis Area Severity Index (aPASI) was ≤3 for 7 and 6 patients at weeks 12 and 24, respectively. Affected BSA and DLQI demonstrated similar improvements. Treatment was terminated in 3 patients due to AEs (diarrhea and lymphopenia). In this case series, simplified DMF dosing was largely well-tolerated and provided similar efficacy to the current scheme. Higher doses were reached more quickly and the dosing regimen was simpler for patients (twice instead of three times daily).
