Study Summary

Acne vulgaris is a multifactorial disease caused by overgrowth of Propionibacterium acnes (P. acnes), impaction of hair follicles, excessive sebum production and hormonal dysregulation. Recent literature from the Human Microbiome Project has shown there are unique microbial signatures specific to healthy and acne disease states. From this data, the investigators hypothesize that by eliminating resident disease-associated bacterial strains and replacing them with health-associated strains, recurrences/fares of acne may be improved, mitigated, and prevented. Instead of current approaches which focus on eliminating all bacteria from the skin, the investigators aim to deliver healthy bacteria to restore the skin to a healthy state via this replacement therapy. The investigators aim to test this in a Phase Ib single application study evaluating the safety, tolerability, and clinical impact that a single application of NB01, a live strain of P. acnes, has on adult subjects with moderate acne.

Primary Outcome

Engraftment is defined as the percentage of bacteria recovered from hair follicles that are health-associated (NB01) as measured with proprietary quantitative polymerase chain assays. Successful follicular engraftment, defined as both deoR/PanBac \>40% and Cas5/PanBac \>40% in the Day 2 (24H) ) Biore Strip samples. Cas5/PanBac and deoR/PanBac are the percentages of bacteria in a sample containing the CRISPR associated protein Cas5 and a repressor of porphyrin production deoR, respectively. Pan-B
