Background and study aims
Some head louse treatments are not effective because they are difficult to use or are affected by insecticide resistance. This trial looked at a shampoo containing soya oil as an active material to coat the lice (mosquito®LäuseShampoo) and compared it with an insecticide-based product containing 0.5% permethrin used extensively in Germany (InfectoPedicul® lotion).

Who can participate?
Anyone over 2 years of age who had head lice could take part.

What does the study involve?
The participants were randomly allocated to receive one of the two treatment methods: shampoo or lotion. Both treatments were applied on the first day, with repeat treatment after 9 days, and there were four follow-ups over 2 weeks to see how well they worked.

What are the possible benefits and risks of participating?
The possible benefit of the trial was that patients could get rid of their head lice without charge. The possible risks of the trial were discomfort or irritation where the treatment was applied either during or after the treatment.

Where is the study run from?
Medical Entomology Centre, Insect Research & Development Limited, UK.

When is the study starting and how long is it expected to run for?
The study started in June 2010 and ran until December 2010.

Who is funding the study?
Wepa Apothekenbedarf GmbH & Co KG.

Scientific titleA randomised, controlled, assessor-blind, clinical investigation of the activity of mosquito® LäuseShampoo compared with Infectopedicul® permethrin 0.5% lotion in the treatment of head lice
Study objectivesTo investigate:
1. Non-inferiority of mosquito® LäuseShampoo to Infectopedicul® in the eradication of head louse infestation
2. If a sufficient difference in efficacy is identified to detect superiority of mosquito® LäuseShampoo compared with Infectopedicul®
3. To compare the products for safety, ease of application and participant acceptability
Ethics approval(s)Added 05/02/2014: Oxfordshire REC Committee A, ref: 10/H0604/30
Health condition(s) or problem(s) studiedHead louse infestation
InterventionParticipants will be randomly divided into two equal groups.

Half the participants (48) will receive mosquito® LäuseShampoo (modified coconut oil and soya oil based shampoo): the product is first used like an ordinary shampoo and partially towel dried. The product will be applied directly to the damp hair. Sufficient product will be applied to the hair and scalp that when thoroughly massaged in produces a homogenous and stable foam, which covers all the hair and the scalp. If no such foam is built, more product has to be applied. The foamed product will be left in place for 30 minutes (a shower cap will be used to secure the foam) before being rinsed off with warm water and towel dried. The product is then reapplied to produce a stable foam and left in place for a further 30 minutes (maximum dose 100 ml per treatment application). The product will be reapplied at Day 9.

The other half (48) will receive Infectopedicul® 0.5% permethrin alcoholic lotion: The product will be applied directly to washed and towel dried hair. Sufficient product will be applied to saturate the hair and scalp (maximum dose 100 ml per application). The product will be left in place for 30 minutes before being rinsed off with warm water. The product will be reapplied at Day 9.

PhasePhase IV
Drug / device / biological / vaccine name(s)mosquito® LäuseShampoo, Infectopedicul® lotion
Primary outcome measureTo investigate the non-inferiority of mosquito® LäuseShampoo in comparison with Infectopedicul® lotion in the eradication of head louse infestation, defined as no evidence of head lice, assessed between completion of the second application of treatment on day 9 and day 14 (the first treatment being applied on day 0).
Secondary outcome measures1. If there is sufficient margin in efficacy, to detect superiority of efficacy of mosquito® LäuseShampoo over Infectopedicul® lotion in the eradication of head louse infestation
2. To compare mosquito® LäuseShampoo with Infectopedicul® lotion with regard to the following factors:
2.1. Safety of the products monitored by observation for adverse events on days 0, 2, 9, 11, and 14 of the study
2.2. Ease of use by investigators, assessed by a questionnaire on the day of the first treatment
2.3. Participant acceptability, assessed by a questionnaire at the assessment on day 2
