Brief Summary:
Double Blind, Three Cohort, Placebo-controlled Trial to Assess Safety, Tolerance and Induced Bacterial Colony Counts of Three Ascending Doses of AZT-04 in Healthy Adult Volunteers

Condition or disease Intervention/treatment Phase
Study of Three Doses of AZT-04 for Skin Appearance Other: AZT-04 Not Applicable

Detailed Description:

This is a single-center, prospective, double-blind, three cohort pilot study to assess the tolerability and induced changes in skin microbiome population and diversity of three ascending doses of test article code AZT-04 in normal, healthy subjects.

The study will consist of up to 7 scheduled study visits. There will be three cohorts in this study, each cohort composed of 6 subjects (total number of subjects is at least 18). Each cohort will be treated with both a placebo ointment and an ointment containing different concentrations of the Staphylococcus epidermidis. Approximately 1 ml of placebo ointment and 1 ml of AZT-04 ointment (test product composed of a commensal strain of Staphylococcus epidermidis) will be applied topically to two separate skin sites on the back, each site approximately 8 x 5 cm. Skin microbiome sampling will be performed before application of any test article (i.e., baseline) and each subsequent day for four (4) consecutive days. Samples will be shipped to a laboratory chosen by the Sponsor for analyses

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Safety and Tolerance: mean erythema [ Time Frame: 9 days ]
    to demonstrate the tolerability of three different doses of AZT-04 containing Staphylococcus epidermidis compared to placebo in healthy adult population--as s measured by mean erythema scores


Secondary Outcome Measures :
  1. Bacterial Count [ Time Frame: 9 days ]
    to assess the colonization of the test articles and placebo treated sites as it relates to the number of colony forming units (CFU's) over time after application and overall change in the microbiome diversity
