Primary Outcome Measures:
  • Local safety [ Time Frame: April 2010 - November 2010 ]
    The primary objective of this study is to assess the local safety of azithromycin dermal formulation when applied to healthy skin in healthy volunteers. This will be done by determination (in cohort 1) and confirmation (in cohort 2) of the maximal tolerated dose (MTD) after dermal application of SHB001 in 4 different dose regimens.

Secondary Outcome Measures:
  • Pharmacokinetics of SHB001 [ Time Frame: April 2010 - November 2010 ]
    • To assess the pharmacokinetics of azithromycin dermal formulation in the plasma in healthy volunteers after daily administration for three consecutive days in cohort 1 and cohort 2.
    • To assess the pharmacokinetics of azithromycin dermal formulation in the skin in healthy volunteers after daily administration for 1 - 3 consecutive days in cohort 2 only.
    • To demonstrate that the Minimal Inhibitory Concentration (MIC) of B.b. (=0.03μg/ml) in the skin is reached at least for 2 consecutive assessments (biopsies) in cohort 2.
    • To assess general safety in cohort 1 and 2.

Enrollment: 32
Study Start Date: April 2010
Study Completion Date: November 2010
Primary Completion Date: November 2010 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: Application of SHB001
    • Cohort 1: Application of SHB001 on the skin of right thigh
    • Cohort 2:

      1. Application of SHB001 on the skin of right thigh
      2. punch biopsies of treated skin areas
    Other Names:
    • 0% SHB001 azitrhomycin dermal formulation (placebo)
    • 5% SHB001 azitrhomycin dermal formulation
    • 10% SHB001 azitrhomycin dermal formulation
Detailed Description:

In this study two consecutive cohorts will be treated:

  • Cohort 1: 8 volunteers
  • Cohort 2: 24 volunteers, divided into 3 groups of 8 subjects each

The study will be conducted in the following three phases:

  1. Treatment of cohort 1: The aim is to establish the maximal tolerated dose (MTD) for a local treatment with azithromycin dermal formulation.

    1. Treatment of cohort 1 with azithromycin dermal formulation and follow up
    2. Assessment of local safety within the 7 days following the first treatment
    3. The maximal tolerated dose (MTD) will be determined
  2. Treatment of cohort 2: The aim is to confirm the local tolerance of the selected doses and to evaluate the local skin and plasma concentration of azithromycin after application of SHB001 dermal formulation.

    1. Treatment of cohort 2 with azithromycin dermal formulation at maximal tolerated dose (MTD), with a dose one or more concentrations lower than maximal tolerated dose (MTD) and with placebo
    2. Skin biopsies of treated skin areas will be taken for the PK assessment
  3. Study completion examination
