Impetigo Clinical Update (Partnered with Galderma)

Affecting over 1.4 million patients in the U.S., impetigo is a highly contagious superficial bacterial infection of the skin that affects mostly children.  Most cases are caused by Staphylococcus aureus, Streptococcus pyogenes, or a mixture of both organisms.  Methicillin-resistant S. aureus (MRSA) is being observed with increasing frequency in this population.  Impetigo is currently being treated with antibiotic ointments, to which bacteria has developed resistance.

Recently, NovaBay announced top-line results from its randomized, sequential group, double-blind study designed to evaluate the efficacy and safety of three different strengths of NVC-422 topical gel in the treatment of impetigo.  A total of 129 children in the age range 2-12 presenting with impetigo were randomized for treatment with NVC-422 topical gel three times daily for 7 days.  Efficacy evaluations, compared to baseline, were conducted at the end of treatment and one week later.  Clinical and bacteriological response rates for the three concentrations of drug applied ranged from 84% to 95% at end of treatment and at follow-up.  These response rates were substantially higher than the response rate anticipated for placebo (30-50%).  Notably, response rates for MRSA infections were 100% (10/10) across all treatment groups. The clinical and bacteriological response rates across the treatment groups suggested a dose response, although differences were not statistically significant.  Infrequent adverse events were mild to moderate in severity and were predominantly local.

Acne Clinical Update (Partnered with Galderma)

Acne is the most common skin disease that affects people of all races and age groups, but it is most common in teenagers and young adults. An estimated 80 percent of all people between the ages of 11 and 30 suffer from outbreaks of acne at some point, and some people in their 40s and 50s are also affected. There is a clear need for more effective antimicrobial treatments than the currently available antibiotics.
