Study Summary

The study objective is to characterize the shift in the diversity and abundance of the skin microbial community at baseline and in response to Altreno monotherapy as compared to benzoyl peroxide (BPO) 2.5% leave-on gel monotherapy in acne patients.

Primary Outcome

The primary outcome measures the relative abundance of Kingella after treatment with Altreno in acne patients vs without treatment in healthy subjects. The relative abundance was represented as centered log ratio (CLR) transformation. These values are all relative terms centered around 0, more negative means less abundant in comparison. More positive means more abundant in comparison.
