Evidence Threshold for a Precision Medicine Test that Predicts Optimal Response to a Biologic Agent in Patients With Psoriasis: A Consensus Panel.

Precision medicine approaches are receiving increased attention in dermatology, including inflammatory skin diseases. In psoriasis, a precision medicine treatment paradigm could temper the rapid increase in pharmacy costs that have resulted from a tremendous expansion in the number of available biologic drug options. However, without a clear and agreed upon proof of clinical utility in a real-world setting, costly new pharmacotherapies are often burdened with barriers to coverage by payers and ultimately, routine patient care. This panel was assembled to discuss the evidence threshold required to demonstrate the clinical utility of a precision medicine diagnostic that predicts the biologic therapeutic class for treating psoriasis patients. The panel reviewed clinical utility study designs and economic impact study designs aimed at delineating net savings and waste reduction. A psoriasis biologic precision medicine test could optimize pharmacotherapy management of psoriasis patients. The consensus opinion of this panel was that positive results from the study described here would prove the clinical utility of this precision medicine test.
