Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Ha44 is a novel insect ovicide. It is a lotion (0.37% or 0.74%) which is applied topically to the hair and scalp as a single dose at the start of the study. The lotion is washed off after 10 or 20 minutes.
Four groups will be studied, each group consisting of 8 subjects, 6 of whom will be treated with Ha44 and 2 with vehicle only. The vehicle onsists of a number of excipients, all of which are listed on the FDA database of inactive ingredients and within the allowed concentrations.
The first group will be treated with 0.37% Ha44 or vehicle for 10 minutes. After review of 7 day safety data, a second group will be treated with 0.37% Ha44 or vehicle for 20 minutes. After review of their 7 day safety data, a third group will be treated with 0.74% Ha44 or vehicle for 10 minutes. After review of 7 day safety data, a fourth group will be treated with 0.74% Ha44 or vehicle for 20 minutes.
