| Secondary study design | Randomised controlled trial |
| Study type | Participant information sheet |
| Scientific title | A randomised, controlled, assessor-blind, clinical trial to compare Liceko® with Nix® / Lyclear® 1% permethrin creme rinse in the treatment of head lice. |
| Study objectives | To confirm that Liceko® is effective to kill head lice and their eggs using two applications in comparison with two applications of Nix® / Lyclear®, and to identify any significant difference in performance (superiority) of one product over the other in the eradication of head lice. |
| Ethics approval(s) | Not provided at time of registration |
| Health condition(s) or problem(s) studied | Head louse infestation |
| Intervention | Group A Liceko®: The product will be applied directly to dry hair. Sufficient product will be applied to saturate the hair and scalp. The product will be left in place for 20 minutes before being shampooed and rinsed off with water. Group B Nix® / Lyclear® : The product will be applied to washed and towel dried hair. Sufficient product will be applied to saturate the hair and scalp. The product will be left in place for 10 minutes before being rinsed off with water. For both treatments the product will be reapplied at Day 7. |
| Intervention type | Other |
| Primary outcome measure(s) |
Cure of infestation, defined as no evidence of head lice, assessed between completion of the second application of treatment on day 7 and day 14 (the first treatment being applied on day 0). |
| Key secondary outcome measure(s) |
1. Comparison of the efficacy of Liceko® with that of Nix® / Lyclear® crème rinse and to identify superiority of one product over the other if appropriate. |
