A Study to Evaluate the Therapeutic Equivalence of Generic Permethrin Cream 5% to Elimite® in the Treatment of Scabies

Phase 3

Completed

• Conditions: Scabies
• Interventions: Drug: Permethrin

• Registration Number: NCT02572986
• Lead Sponsor: Dr. Reddy's Laboratories Limited

Brief Summary

Scabies is an infestation of the skin by the human itch mite (Sarcoptes scabiei). Diagnosis of scabies is made based on clinical symptoms, such as nocturnal itching, and appearance and distribution of the rash. Definitive diagnosis includes the microscopic identification of the mite, mite eggs, or mite fecal matter in the skin. Topical permethrin is considered the drug of choice for the treatment of scabies. It is a synthetic pyrethroid that is safe for use in adults and children 2 months and older.

This study will evaluate the therapeutic equivalence of a generic permethrin cream 5% to Elimite® in the Treatment of Scabies.
