July 15, 2015 updated by: Medical Entomology Centre

A Randomised, Parallel Group Clinical Trial to Assess the Efficacy, Safety and Acceptability of a Surfactant Based Lotion in the Treatment of Head Louse Infection.

To assess the efficacy and safety of 10% Cocamide DEA using two treatment regimens in the eradication of head lice. To assess the ability of each treatment regimen to kill all viable ova and to assess patient acceptability of the product in use

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

A previous study found that a formulation of 10% cocamide diethanolamine (DEA) aqueous lotion showed some efficacy to eliminate head louse infestation but that the treatment regimen was inadequate to kill all lice or louse eggs. This study has been designed to compare two different application regimens that have been shown effective in vitro.

A planned total of 120 patients who, following examination, are found to suffer from active head lice infestation will be recruited to the trial. The patient will be treated with 10% cocamide DEA lotion using the appropriate treatment regimen according to the randomization code from a pre-prepared listing in balanced blocks of 12.

Group 1: 10% cocamide DEA is applied directly to dry hair, the excess water evaporated off using a hair dryer and is then left for 8 hour/overnight before washing off with clean water.

Group 2: 10% cocamide DEA is applied directly to dry hair, the excess water evaporated off using a hair dryer and is then left for 2 hours before washing off with clean water. A follow up treatment is given after 7 days.

Treatments will be applied by experienced investigators throughout the study. Assessments will be made by other investigators unaware of the treatment regimen used.

After treatment (day 0), follow up assessments will be performed on days 4, 8,11 then again at day 14 after which they will leave the study. Any adverse events or side effects from the treatments will be monitored during the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

  • Phase 3

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

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

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Male and female patients over the age of 4 who are found to have a head louse infection.
  • Patients who give written informed consent and, if the patient is under 16 years of age, whose guardian gives written informed consent to participate in the study.
  • Available for the duration of study i.e. 15 days.

Exclusion Criteria:

  • Patients with a known sensitivity to paraben preservatives.
  • Patients who have been treated with other head lice products within the last 2 weeks.
  • Patients who have undergone a course of antibiotic treatment within the last 4 weeks.
  • Patients who have any persistent skin disorder of the scalp (i.e. eczema, chronic dermatitis, psoriasis).
  • Patients whose hair has been bleached, colour treated or permed within the last 4 weeks.
  • Patients who have participated in another clinical trial within 1 month prior to entry to this study.
  • Patients who have already participated in this clinical trial.

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
Successful elimination of infestation
Time Frame: 14 days
No evidence of active head lice infestation 14 days after enrolment
14 days

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
Number of participants with treatment related adverse events as a measure of safety
