A Randomized, Double-Blind, Parallel-Design, Multiple-Site Study to Evaluate the Therapeutic Equivalence of Permethrin Cream 5% (Encube Ethicals) Compared to Elimite™ Cream (permethrin) 5% (Prestium Pharma, Inc.) in the Treatment of Scabies.

The objectives of this study are to:

• Evaluate the therapeutic equivalence of the Test formulation, Permethrin Cream, 5% (Encube Ethicals) to the marketed product, Elimite™ Cream (permethrin) 5% (Prestium Pharma, Inc.) in patients with scabies.
• Compare the safety of Test and Reference treatments in patients with scabies.

Inclusion criteria

• Male or non-pregnant, non-lactating female, 2 years of age or older.
• If female and of childbearing potential, prepared to abstain from sexual intercourse or use a reliable method of contraception during the study (e.g., double barrier methods, intrauterine device (IUD), oral, transdermal or injected hormonal contraceptives). Female patients using hormonal contraceptives should have been on the same product/dosing regimen for at least 28 days before baseline and should not change this regimen during the study.
• Signed informed consent that meets all criteria of current FDA and International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH) regulations. For patients 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 patient "assent" form, as appropriate. Patients 11-17 years of age will read and sign an Independent Review Board (IRB)-approved assent form and patients 6-10 years of age will provide verbal assent. Patients 2-5 years of age will be exempt from providing assent based on the child's comprehension and cognitive skills.
• Clinical diagnosis of active scabies by presence of a burrow and/or typical scabietic lesions at the classic sites of infestation.
• Parasitological confirmation of clinical diagnosis with demonstration under light microscope of mites and/or their products (larvae, eggs or fecal material).
• Symptom score of 2 or 3 on a 4-point rating scale of 0-3 for nocturnal itching/pruritus.
• Ability to apply or have study product applied as directed. If patient is a child, then parent/guardian will apply study product to him/her.
