BPX-01 Minocycline 1% Topical Gel for Reduction of Propionibacterium Acnes

Study Overview
=================
Brief Summary
-----------------
This is a Phase 2a study which is being conducted in healthy volunteers in order to evaluate the comparative reduction of Propionibacterium acnes in-vivo following once daily topical administration of BPX-01 Minocycline 1% Topical Gel (BPX-01) or BPX-01 Vehicle control.

Detailed Description
-----------------
The objective of this study is to evaluate the comparative reduction of Propionibacterium acnes (P. acnes) in-vivo following once daily topical administration of BPX-01 Minocycline 1% Topical Gel or BPX-01 Vehicle control Gel. A secondary objective is to assess the tolerance of the treatment regimen versus a vehicle control. Safety laboratory data (chemistry and hematology) and plasma levels of minocycline are also of significant interest to the sponsor. This is a single center, randomized, double blind, two-cell, vehicle controlled P. acnes study. All subjects will be randomized 2:1 to 1% BPX-01 or vehicle control to be applied as a topical gel once daily for four (4) weeks. This is a six (6) week study with a four (4) week treatment period and a two (2) week post treatment follow up visit. The clinical endpoint is in-vivo quantification of P.acnes. The safety/tolerance endpoints are; observer reported: erythema, scaling-peeling, edema, and subject reported: tightness, burning-stinging, and itching. Plasma levels of minocycline and basic hematology and chemistry laboratory values will be collected.
