A non-invasive predictive diagnostic test for psoriasis. A dermal biomarker patch collects skin RNA in about five minutes, and Mindera's laboratory and machine learning models assess roughly 100 mRNA biomarkers to determine which biologic therapy a patient is likely to respond to.

• ·Penny-sized dermal biomarker patch, painless and applied in about five minutes
• ·Extracts thousands of RNA transcripts from the skin without a punch biopsy
• ·Assesses roughly 100 mRNA biomarkers predictive of biologic drug response
• ·Machine learning models trained on patient-specific transcriptome data
