The purpose of the study is to evaluate the safety and tolerability of a single application of Ha44 Gel 0.74% w/v for the treatment of head lice under maximal use conditions.
Secondary objective is to evaluate pharmacokinetics of Ha44 and benzyl alcohol (contained in Ha44 vehicle) under maximal use conditions.
|Condition or disease||Intervention/treatment||Phase|
|Head Lice Infestation||Drug: Ha44 Gel||Phase 2|
This is an open-label safety and pharmacokinetic (PK) study involving a single application of Ha44 Gel 0.74% administered under maximal use conditions.
All participants must have an active head lice infestation (at least 3 live lice) and be 6 months to 17 years of age. The study will enroll approximately 36 pediatric subjects between the ages of 6 months and 17 years.
Pediatric PK samples will be collected at 0 (predose), 30 and 60 mins and 2 and 8 hrs time points.
More than one household member with an active lice infestation may participate in the study. Eligible subjects will be consented and screened for study eligibility on Day 0 (Visit 1). All subjects will return to the study site for three follow-up clinic visits at Days 1, 7 and 14. The maximum study duration for a subject is 16 days.
