Summary:

      This is a multi-center, double-blind, randomized, two arm parallel design study. This study
      is comprised of two phases: screening and treatment. The screening period will be up to 5
      days, followed by the treatment phase of 28±4 days. During the treatment phase subjects will
      be randomized to receive either test or reference treatments in a double-blind manner in an
      outpatient setting. Randomization of subjects will be in a 1:1 ratio for the test and
      reference drug arms and will be stratified by site.

      Screening will begin at visit 1, during which eligibility will be determined and prohibited
      treatments will be discontinued. Randomization will occur following the confirmation of the
      eligibility criteria at visit 2 (baseline, Day 1) i.e. initiation of treatment phase. The
      treatment phase will be 28±4 days in duration wherein subject will receive treatment with
      investigational product (either test or reference) on Day 1 or Baseline (visit 2). Safety and
      tolerability assessments will be performed on Day 7 (visit 3). Efficacy, safety and
      tolerability will be assessed on Day 14 (visit 4) followed by the End of study visit on Day
      28 (visit 5). If positive identification of scabies is confirmed at Day 14 (visit 4), the
      subject will be retreated with the second application of the investigational product.

          4. Subjects must be willing to make every effort to immediately disinfect clothes,
             towels, and linens and all potentially infected household items upon diagnosis of
             infestation to prevent re-infestation.

          5. All household members with prolonged physical contact with the subject must be willing
             to attend Baseline visit and receive treatment with standard of care if deemed

          6. Subject or representative must read and sign an Institutional Review Board/Independent
             Ethics Committee (IRB/IEC) approved Informed Consent Form (ICF); for minor subjects
             (18 years or younger in most states) the parent or legal guardian should sign the ICF
             and the child will be required to sign the Assent Form that will written in such a way
             as to be understandable to a child.

          7. Subject must be able to apply study product to self. If the subject is a child, then
             parent/guardian will apply study product to him/her.
