e15045 Background: Human papillomavirus (HPV) is an oncogenic driver of several human cancers, including those of the anal canal, uterine cervix, and head and neck (predominantly oropharynx). Despite advancements in our understanding of HPV-related cancers, there remains an unmet need for a comprehensive biomarker-driven registry to establish correlations between biomarker detectability and clinicopathologic features in patients diagnosed and treated for HPV-driven cancers. To address this need, the NAVigate-HPV Registry has been established to systematically collect and analyze integrated biomarker and clinical data from many U.S. cancer centers. Methods: NavDx (Naveris, Inc.) is a clinically validated blood-based assay detecting circulating cell-free tumor tissue modified viral (TTMV)-HPV DNA. The NAVigate-HPV Registry is a web-based data platform based on a centrally IRB approved protocol. Participating investigators will include providers that order NavDx tests in the routine clinical care of their patients and agree to the terms and conditions for use of the registry. Eligible subjects will have or have had an HPV-driven cancer (with an initial focus on HPV-driven oropharynx cancer with confirmatory tissue testing) and have received one or more NavDx blood tests during routine clinical care. Clinical data and TTMV-HPV DNA scores will be collected at enrollment and defined intervals over five years or until death. Results: In the initial phase, the registry has enlisted participation and established a steering committee composed of a representative from each of 14 institutions. These institutions are geographically diverse centers ranging from community hospitals to clinics and academic medical facilities. An IRB protocol governing the registry will maintain ethical standards, ensuring compliance and ethical conduct throughout the registry process. Data extraction methods have been previously established to evaluate an initial cohort of 543 patients (Hanna GJ, Roof SA, et. al 2023). Conclusions: Naveris and collaborators have together successfully launched the NAVigate-HPV registry with the aim of creating a robust database linking tumor biomarker results from NavDx with clinical outcomes data for HPV-related cancers. The NAVigate-HPV database is expected to encompass more than 1,000 patients within 1 year and grow to &gt; 5,000 patients within 5 years, serving as a powerful tool for precision cancer medicine in this patient cancer population. Establishing this registry will deepen insights into HPV-related cancers and advance diagnostic and therapeutic approaches to improve patient outcomes.
