  • ("Pernix") (NYSE Amex: PTX), a specialty pharmaceutical company primarily focused on the pediatric market, and ParaPRO, LLC today announced the commercial launch of Natroba™ (spinosad) Topical Suspension, 0.9%, an FDA-approved prescription treatment for head lice in patients four years of age and older.

  • Natroba™ treats head lice using spinosad, a compound derived from a soil microbe.

  • At the time of the announcement ParaPRO had submitted a drug candidate containing the API spinosad to the FDA seeking approval for the treatment of head lice.

  • The trials compared the efficacy of spinosad with that of permethrin Nix.

  • Based on the apparent advantages of spinosad over the current standard of care, along with a U.S. market for head lice treatment estimated at approximately $240 million, we think this deal with ParaPRO could be potentially very lucrative for Pernix.

  • Results showed that approximately 85% (trial 1) and 87% (trial 2) of spinosad-treated participants were lice free after 14 days.

  • The study authors thus concluded that spinosad was significantly more effective that permethrin for the treatment of head lice.
