The first segment, is a procedural pilot conducted prior to the main study, that is aimed at ensuring optimal execution of the FNA procedure. During the procedural pilot, core needle biopsy (CNB) will be performed on participants as part of their standard of care, but no study drugs will be administered, nor will any procedures other than FNA be conducted. The second segment, the main study, is designed to evaluate the feasibility of measuring Grazoprevir by FNA. During the main study, drugs will be administered, and other additional procedures will be conducted.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '65
