Detailed Description:
This is a sequentially staged (Stage 1-4), proof of concept study assessing the safety of photodynamic therapy (PDT) and lemuteporfin topical solution (LTS) in healthy subjects and subjects with mild acne. Approximately 12 subjects will be enrolled in Stage 1 in order to determine a maximum tolerated light dose following LTS application. Up to 90 subjects with mild acne will be enrolled in Stage 2 in order to assess the safety of PDT following a single LTS application. Up to 50 subjects will be enrolled in Stage 3 in order to assess the safety of PDT following repeat LTS applications. Up to 40 subjects will be enrolled into Stage 4 to assess multiple treatments of LTS-PDT.
