Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

2 years and older (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Inclusion Criteria:

  1. Subjects must have an active head lice infestation present at Day 0.
  2. Subjects can be female or male, at least 6 months of age.
  3. Subjects must be in good general health based on medical history.
  4. Each subject must have an appropriately signed Informed Consent agreement. Subjects under the age of 12 must also provide written or oral assent.
  5. The subject/caregiver must be able to read English or Spanish at a 7th grade level.

  8. Subjects must agree not to cut or chemically treat their hair in the period between the initial treatment and the final visit.

Exclusion Criteria:

  1. Individuals with history of irritation or sensitivity to pediculicides or hair care products.
  2. Individuals with any visible skin/scalp condition at the treatment site which, in the opinion of the investigative personnel or Sponsor, will interfere with the evaluation.
  3. Individuals who require treatment with topical salicylic acid, topical corticosteroids, anthralin, vitamin D analogs, retinoids, immunosuppressants, topical hair growth formulations, and topical dandruff treatments.
  4. Infested subjects who have been previously treated with a pediculicide within the 48 hours prior to the study.
  5. Individuals with a condition or illness that, in the opinion of the Investigator, may compromise the objective of the protocol.

  10. Females who are pregnant or nursing. Females of childbearing potential must have a negative urine pregnancy test prior to treatment at Day 0. If a household has a pregnant female with an active case of head lice, the entire household is excluded from participation.

  11. Sexually active females not using effective contraception.
  12. Individuals who have a history of drug abuse in the past year.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Efficacy of NatrOVA Creme Rinse - 1% Relative to NIX Creme Rinse in Subjects Infested With Head Lice
Time Frame: Assessment were made 14 days following the final product treatment
The primary efficacy endpoint was the proportion of primary subjects in the enrolled households who were lice free (no live lice, adults or nymphs), as assessed by the trained evaluator, 14 days after the last treatment (i.e., Day 14 for subjects who treated once and Day 21 for subjects who treated twice).
Assessment were made 14 days following the final product treatment

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Evaluation of the Safety of NatrOVA Creme Rinse - 1% Based Upon Reported Adverse Events and Observed Skin/Scalp Reactions.
Time Frame: Participants were followed for a minimum of 14 days (1 treatment) and a maximum of 21 days (2 treatments)
To evaluate the safety of NatrOVA® 1% Creme Rinse based upon reported adverse events and observed skin/scalp reactions. Additional safety assessments included cutaneous/ocular irritation.
