A Dose Ranging Vehicle Controlled Study to Determine the Safety and Efficacy of Permethrin Foam, 5% and Permethrin Foam, 4% for the Treatment of Scabies

Change in Disease-related Signs and Symptoms for Those Subjects Provided With Re-treatment at Day 14 Who Show Improvement in Their Investigator's Global Assessment (IGA) Score at Day 28

The change in the total score of signs and symptoms related to the condition in each treatment group at Days 14 and 28, as well as at Day 42 for those subjects provided with re-treatment at Day 14 who show improvement in their IGA score at Day 28. Scale details: The overall average presence of the individual signs and symptoms of scabies was evaluated over the entire body. Erythema, papules, pustules, crusting, scaling, excoriations, and pruritus were assessed as follows for each sign and symptom: None=0, Trace=1, Mild=2, Moderate=3, Severe=4. From these assessments, the total score of the Signs and Symptoms (from 0 to 28, higher scores mean a worse outcome) was calculated as the sum of the individual signs and symptoms scores at Baseline and Days 2, 14, 28, and 42 (if applicable).The change from baseline in the total score can range from -28 as the best reduction possible (better outcome) to +28 as the worst increase possible (worse outcome) in signs and symptoms.

Time frame: Baseline, Day 14, 28, and 42

Number of Re-treated Subjects Designated as "Treatment Success"

Each subject was designated as "re-treatment success" at Day 42 based upon the criteria in the protocol to which he/she was enrolled. In protocol v2.0, "treatment success" was defined as an Investigator's Global Assessment (IGA) score of 0 (clear) or 1 (almost clear). In protocol v3.0, "treatment success" was defined as an "eradication of infestation": a) no burrows, b) a reduction in the Signs/Symptoms, and c) no evidence of a live mite on microscopy.
