Inclusion criteria
. Signed Institutional Review Board (IRB)-approved informed consent form that meets all criteria of current FDA regulations. For participants who are considered minors in the state the study is being conducted (\<18 years in most states), the parent or legal guardian should sign the consent form and the child will be required to sign a participant "assent" form, as appropriate. Participants 11-17 years of age will read and sign an IRB-approved assent form and participants 6-10 years of age will provide verbal assent. Participants 6 months-5 years of age will be exempt from providing assent based on the child's comprehension and cognitive skills.
. The participant and/or the participant's parent (legal guardian) is willing to apply the study product as directed, comply with study instructions, and commit to all follow-up visits for the duration of the study.
. Male or non-pregnant, non-lactating female, 6 months of age or older.
. Females of childbearing potential must not be pregnant or lactating at Visit 1 (Day -1 to 1) (as confirmed by a negative urine pregnancy test with a sensitivity of less than 50 milli-international units/milliliter \[mIU/mL\] or equivalent units of human chorionic gonadotropin). Women of childbearing potential must agree to the use of a reliable method of contraception. (for example, total abstinence, intrauterine device, a double-barrier method, oral, transdermal, injected, or implanted non-hormonal or hormonal contraceptive) throughout the study. Female participants using hormonal contraceptives should have been on the same product/dosing regimen for at least 28 days before Visit 1 (Day -1 to 1) and should not change this regimen during the study. A sterile sexual partner is not considered an adequate form of birth control.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Percentage of Index Participants Who Were Considered a Treatment Success: PP Population
Timeframe: Day 15 ± 2
2
Percentage of Index Participants Who Were Considered a Treatment Success: mITT Population
. Index participants (that is, the youngest household member) must have an active head lice infestation, defined as ≥3 live lice (that is, live adults and/or nymphs), at Visit 1 (Day -1 to 1).
. Household members participating in the study must have ≥1 live louse (that is; live adults and/or nymphs) at Visit 1 (Day -1 to 1).
. All members of the household must be present for examination. Any male head of household who is unable to attend Visit 1 (Day -1 to 1) may be assessed by a second member of the household as being lice free.
Exclusion criteria
. Females who are pregnant, lactating or planning to become pregnant during the study period.
. Participants who do not have a known household affiliation with their household members (that is, do not stay in 1 household consistently, sleeping at 1 place several nights and then at another place or location). Household is defined as living in a shared area or space (for example the same house or apartment unit).
. Any infested member of the household is unable or unwilling to be treated with the study product. This includes male heads of household who do not attend Visit 1 (Day -1 to 1) but report infestation with lice.
. More than 3 members of the household infested with lice.
. Presence of visible skin/scalp condition(s) or open wounds at the application site that are not attributable to head lice infestation and that in the opinion of the Investigator will interfere with safety and/or efficacy evaluations.
. Presence of eczema or atopic dermatitis at the application site.
. Use of any prescription, over-the-counter, or home remedies for the treatment of head lice within 7 days before Visit 1 (Day -1 to 1).
. Use of pediculicides within 4 weeks before Visit 1 (Day -1 to 1).
