Purpose
This is a randomized, double-blind study comparing 0.1% NVC-422, 0.5% NVC-422 and 1.5% NVC-422 topical gel in children with impetigo.

- Clinical Response [ Time Frame: End of Treatment (Day 8) and Follow-up (Day 15) ] [ Designated as safety issue: No ]Sufficient resolution of signs and symptoms of infection of the target lesion such that no additional antimicrobial therapy is required to treat the impetigo as evidenced by the SIRS score of 0 each for exudate/pus, crusting and pain and 0 or 1 each for erythema/inflammation and itching for a clinical success or a SIRS score of 0 for exudate/pus but does not meet all the criteria for clinical success for a clinical improvement.
- Bacteriological Response [ Time Frame: End of Treatment (Day 8) and Follow-up (Day 15) ] [ Designated as safety issue: No ]The causative pathogen isolated from the target lesion at Baseline (Staphylococcus aureus and/or Streptococcus pyogenes) are eliminated on culture, or response is such that no material was available for culture and therefore is evidence of pathogen eradication.

Detailed Description:
This study is a randomized, sequential group, double-blind study. The first 60 subjects enrolled will be randomized to either 0.1% NVC-422 or 0.5% NVC-422. Randomization is 1:2 where 20 subjects will receive 0.1% NVC-422 and 40 subjects will receive 0.5% NVC-422. If there are no safety issues regarding the first 2 doses tested, the next 60 subjects will be randomized to either 0.1% or 1.5% NVC-422 with 20 subjects receiving 0.1% and 40 subjects receiving 1.5% NVC-422.
The lesion most representative of the subject's infection will be identified as the target lesion. This target lesion will be photographed, graded clinically, and its location recorded. At Visit 1, Screening and/or Baseline, a Gram stain will be performed to assess presence of Gram-positive cocci. If Gram-positive cocci are present, a swab for culture and sensitivity will be obtained. Treatment will began immediately after randomization.
Treatment will be 3 times per day (TID) for 7 consecutive days, following a morning, afternoon, and evening schedule.
After the start of treatment (Day 1), subjects will be assessed for safety on Day 4 (± 1). Clinical and bacteriological assessments of the target lesion will also occur on Day 8 (+1) and Follow-up on Day 15 (± 2).
