BACKGROUND: Chronic spontaneous urticaria (CSU), a mast cell-driven condition, is debilitating, common, and hard to treat. Miltefosine, a lipid raft modulator, can inhibit mast cell responses in vivo.
OBJECTIVE: To study the safety and efficacy of systemic miltefosine treatment in CSU patients resistant to standard-dosed antihistamines.
METHODS: In this investigator-initiated multicentre, randomized, double-blind, placebo-controlled study, CSU patients were treated for 4 weeks with daily doses of up to 150-mg miltefosine (n = 47) or placebo (n = 26). Disease activity was assessed using the urticaria activity score. Safety and tolerability of miltefosine were also assessed.
RESULTS: After 4 weeks of treatment, Urticaria Activity Score (UAS7) levels were substantially more reduced in miltefosine-treated patients (-6.3 vs. -3.5 in placebo-treated patients; P = 0.05). Also, the number of weals, but not the intensity of pruritus, was significantly reduced in miltefosine-treated patients vs. placebo-treated patients (P = 0.02). In general, adverse events were frequent in both groups (miltefosine: 88%, placebo: 65% of patients) but mostly mild to moderate in severity. We did not observe any serious adverse events.
CONCLUSIONS: The results of this study indicate that miltefosine is an effective and safe treatment option for CSU patients who do not respond to standard-dosed antihistamines.
