The IMC-I109V study is divided into 3 main parts: Part 1 - Single Ascending Dose (SAD); Part 2 - Multiple Ascending Dose (MAD), in HBeAg-negative CHB; Part 3 will evaluate safety, tolerability, antiviral activity, PK and anti-tumor efficacy of Multiple Ascending Doses of IMC-I109V in participants with HBV-associated hepatocellular carcinoma (HBV HCC) who are virally suppressed on NA therapy.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '65 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria\n\nParts 1 and 2:\n\n* ≥18 to 65 years old at time of informed consent\n* HLA-A\\*02:01 positive\n* Documented evidence of CHB based on one of the following: a.
