Patients with anti-HCV(+) or anti-HIV(+) can be enrolled if: 1. anti-HCV(+) with undetectable HCV RNA = 3 months. 2. anti-HIV(+) with undetectable HIV viral load (either with or without Highly Active Anti- Retroviral Therapy, HAART). Exclusion Criteria: 1. Clinically significant illness or surgery that might interfere with study participation. 2.

Any history or presence of poorly controlled or clinically significant medical conditions that are not suitable to receive interferon-based treatment, at the discretion of the investigator: major psychiatric (including but not limited to those with severe depression, severe bi-polar disorder, schizophrenia, suicidal ideation or history of suicidal attempt), neurological, cardiovascular, pulmonary, hematologic, immunologic, autoimmune diseases, thyroid or other endocrine diseases, metabolic (e.g. diabetes mellitus with HbA1C > 8.0%) or other uncontrolled systemic disease, coagulation disorders or blood dyscrasias. 5. Pregnant subject; female subject who are breast feeding or lactating; female subject or the spouse of male subject, with child-bearing potential who is unwilling or unable to practice adequate contraception, defined as vasectomy in men, tubal ligation in women, or use of condoms and spermicides, or birth control pills, or intrauterine devices throughout the study. 6. History of severe allergic or hypersensitivity reactions, e.g. hypersensitivity to the active substance or to any of the excipients of ropeginterferon alfa 2b, ursodeoxycholic acid, tenofovir disoproxil fumarate and tenofovir alafenamide. 7. Therapy with any systemic anti-viral treatment, anti-neoplastic, or immunomodulatory treatment (including supraphysiologic doses of steroids and radiation) within 1 month (3 months for those with long elimination half-lives) prior to the first dose of study drug. 8. A depot injection or an implant of any drug within 3 months prior to administration of study medication, other than contraception or hyaluronic acid injections in joints for osteoarthritis. 9. Body organ transplant or taking immunosuppressant. 10. Use of an investigational drug within 4 weeks prior to the first dose of the study drug. 11. History of malignancy diagnosed or treated within 5 years prior to screening (except for localized treatment of squamous or non-invasive basal cell skin cancers; cervical carcinoma in situ); cancer survivors not on maintenance therapy within the past 5 years. 12. History of opportunistic infection (e.g., invasive candidiasis or pneumocystis pneumonia). 13. Serious localized infection (e.g., cellulitis, abscess) or systemic and life-threatening infection (e.g., septicemia) within 3 months prior to screening. 14. Clinically significant medical conditions known to interfere absorption, distribution, metabolism or excretion of the study drugs. 15. Decompensated liver disease, which includes but not limited to the following: total bilirubin = 2 mg/dL (except in Gilbert syndrome), direct bilirubin = 2X ULN, albumin level < 3.5 g/dL, INR = 1.5; clinical evidence of ascites, liver decompensation, hepatic encephalopathy, oesophageal varices or cirrhosis as identified by ultrasound or any other examination before study entry. 16. Significant steatohepatitis by ultrasound or other examination at the discretion of investigator. 17. Other form of significant chronic liver diseases, except those mentioned above. 18. Significant or major fundoscopic findings at screening including but not limited to retinal exudates, hemorrhage, detachment, neovascularization, papilloedema, optic atrophy, microaneurysms and macu-lar changes. 19. Patients with complete biliary obstruction, chololithiasis, severe pancreatic disease or peptic ulcer. 20. Patients treated by monotherapy of telbivudine/TDF/TAF/adefovir dipivoxil or any other combination therapy with telbivudine/TDF/TAF/adefovir dipivoxil within 1 month prior to screening. 21. Patient who vaccination with any live attenuated vaccine within 1 month prior to screening. |
