Pediculosis - single application

Trial or other data

Nov 16: results from two PIII trials (NCT02060903, NCT02062060; total n=704) have been presented at the American Academy of Pediatrics 2016 National Conference. Participants, of whom about a third were children, had active head-lice infestation and were treated as households with a single application of abametapir 0.74% lotion or the lotion vehicle as placebo; primary outcome was proportion of index subjects lice-free at 14 days follow-up. For the two studies, in the total abametapir index subject group (n=187), cure rate was 88% and 81%, compared with 62% and 60.5% in the placebo groups (n=192 index subjects), p<0.001 for both trials. A high placebo response was expected as the vehicle contains mineral oil, which will act as a suffocant [1].
