title: A randomized trial of amorolfine 5% solution nail lacquer combined with oral terbinafine compared with terbinafine alone in the treatment of dermatophytic toenail onychomycoses affecting the matrix region.
abstract: In view of recent advances in the development of antifungal agents, this study examined the possible synergy of two new antifungal agents, terbinafine and amorolfine. The study compared two different courses of terbinafine treatment combined with amorolfine 5% solution nail lacquer. Terbinafine was given orally for 6 (AT6 group) or 12 weeks (AT12 group) and amorolfine nail lacquer applied weekly for 15 months. A control group received terbinafine alone for 12 weeks. This was a randomized, prospective, open study of severe dermatophyte toenail onychomycosis with matrix region involvement. Nail samples were taken before the start of the study, at inclusion and at the visits at 6 weeks, 3, 9, 15 and 18 months. To assess the value of such combined therapy we chose an early parameter as the principal outcome variable, which was the result of mycological examination, including direct microscopy and culture, at 3 months (allowing a margin of 15 days). The secondary parameters of success were the mycological results at the later visits, clinical evaluation and a combined mycological-clinical response. Safety and tolerance were also assessed. Adverse events were recorded and liver function tests were performed monthly during the terbinafine treatment. Of the 147 patients included in the trial, 121 attended the 3-month visit, within a time limit of 15 days of 3 months after the beginning of treatment: 40 in the AT6 group, 40 in the AT12 group and 41 in the control group. In all, 32 of 121 patients (26. 4%) had negative mycological results on direct microscopy and culture: 14 of 40 (35.0%) in the AT6 group, 11 of 40 (27.5%) in the AT12 group and seven of 41 (17.1%) in the control group. The cure rate for the global (mycological and clinical cure) response measured at 18 months in 145 patients was 44.0% (22 patients) in the AT6 group, 72.3% (34 patients) in the AT12 group and 37.5% (18 patients) in the terbinafine group. These results suggest that the combination of amorolfine and terbinafine may be of value in the treatment of severe onychomycosis. At the same time a pilot pharmacoeconomic analysis was performed demonstrating a better cost per cure ratio for the patients receiving combination treatment.
