Safety, Skin and Plasma Concentration of Azithromycin Dermal Formulation

Phase 1
Completed
Conditions
Lyme Disease
Registration Number
NCT01243008
Lead Sponsor
University of Zurich
Brief Summary

IXODES GmbH intends to develop SHB001, an azithromycin dermal formulation in order to prevent Lyme disease at early stages of infection after tick bite.

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

Primary Outcome Measures
NameTimeMethod
Local safetyApril 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
NameTimeMethod
Pharmacokinetics of SHB001April 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.
