SMART Use of Biologics in Chronic Rhinosinusitis With Nasal Polyposis (CRSwNP)
The prevalence of Chronic Sinusitis with Nasal Polyps (CRSwNP) in the United States is estimated at roughly 4%, which equates to over 13 million Americans. Until recently, the only medical treatment options available for patients with CRSwNP were corticosteroids, with surgery reserved for medical failure. The development of biologic medications over the last 5 years has revolutionized the treatment of CRSwNP. Three biologic medications have been FDA approved and available for the treatment of CRSwNP: dupilumab, omalizumab, and mepolizumab. However, data from the clinical trials for these drugs do not show universal improvement across all patients with CRSwNP. In fact, there is a wide range of outcomes for patients in these trials. The result is that clinicians have no way of knowing which specific biologic would be the best option for any given patient, nor do they know whether biomarkers can be used to predict response to biologics. It is hoped that findings from this study will inform whether any one biologic has superior outcomes to another and whether clinicians can identify patients at baseline who are most likely to improve on biologic therapy.

The 22-item SinoNasal Outcome Test (SNOT-22; ©2006, Washington University, St. Louis, MO) will serve as the primary outcome of interest for all study aims/objectives. The SNOT-22 survey is a CRS-specific QOL instrument containing 22 questions (total summarized score range: 0-110) with high internal consistency and high test-retest reliability. The SNOT-22 utilizes Likert scales numbering from 0 ("No problem") to 5 "Problem as bad as it can be"). The SNOT-22 has been shown to discriminate between subjects with CRS and healthy controls, as well as identify significant differences after both medical and surgical treatments.
