简要总结

This is a randomized, double-blinded, placebo-controlled, multi center, dose ranging study of safety and efficacy in both volunteers with chronic hepatitis B virus infection and in volunteers with hepatitis D virus coinfection. Volunteers will be administered multiple oral doses of ATI-2173 and assessed for safety and efficacy including blood tests to show how the body metabolizes and eliminates the investigational drug as well as how the drug effects the virus infection.

•Is of childbearing potential and agrees to use an acceptable contraceptive method. Acceptable contraceptive methods include:
•Abstinence from heterosexual intercourse from the first study drug administration through to at least 6 months after the last dose of the study drug or until completion of the study, whichever is longer
•Use a systemic contraceptive or an intrauterine device (with or without hormones), from at least 28 days prior to the first study drug administration through to at least 6 months after the last dose of the study drug or until completion of the study, whichever is longer, with a male condom or a diaphragm/cervical cap plus spermicide from the first study drug administration through to at least 30 days after the last dose of the study drug or until completion of the study, whichever is longer
•Male partner vasectomized at least 6 months prior to the first study drug administration OR
•Male partner has had a vasectomy less than 6 months prior to dosing, and the female subject agrees to use an additional acceptable contraceptive method from the first study drug administration through to at least 6 months after the last dose of the study drug or until completion of the study, whichever is longer Or
•Is of non-childbearing potential, defined as surgically sterile (ie, has undergone complete hysterectomy, bilateral oophorectomy, or tubal ligation) or is in a postmenopausal state (ie, at least 1 year without menses without an alternative medical condition prior to the first study drug administration and follicle-stimulating hormone [FSH] levels within the normal ranges for postmenopausal state of the clinical site at screening)
•If male, meets one of the following criteria:
•Is able to procreate and agrees to use one of the accepted contraceptive regimens and not to donate sperm from the first study drug administration to at least 90 days after the last drug administration. Only for Cohort D: male subjects able to procreate must agree to use an accepted contraceptive regimen and not to donate sperm from the first study drug administration to at least 6 months after the last drug administration. An acceptable method of contraception includes one of the following:
•Abstinence from heterosexual intercourse
•Male condom with spermicide or male condom with a vaginal spermicide (gel, foam, or suppository) Or
•Is unable to procreate; defined as surgically sterile (ie, has undergone a vasectomy at least 6 months prior to the first study drug administration)
•Male or female aged at least 18 years but not older than 70 years
•Body mass index (BMI) within 18.0 kg/m2 to 35.0 kg/m2, inclusively
•Light-, non- or ex-smoker (A light smoker is defined as someone using 10.0 nicotine units or less per day for at least 90 days prior to the first study drug administration [refer to APPENDIX 7 for conversions of nicotine usage]. An ex-smoker is defined as someone who completely stopped using nicotine products for at least 6 months prior to the first study drug administration)
•Serum HBsAg positive at screening and at least 6 months prior to screening
•For Cohorts A, B and E only, serum HBeAg positive and HBV DNA ≥ 20,000 IU/mL, or serum HBeAg negative and HBV DNA ≥ 2,000 IU/mL at screening
•ALT and AST < 5 times the upper limit of normal (ULN) at screening and on the day prior to the first study drug administration (Day -1)
•SUBJECTS COINFECTED WITH CHRONIC HBV AND HDV ONLY:
•HDV RNA in serum ≥ 500 IU/mL at screening and evidence of HDV infection (HDVAb or HDV RNA) at least 6 months prior to screening
•SUBJECTS IN COHORT D ONLY:
•Serum HBsAg levels ≥ 100 IU/mL at screening

排除标准

•Female who is pregnant according to the pregnancy test at screening or prior to the first study drug administration
•History of significant hypersensitivity to clevudine, tenofovir disoproxil fumarate or any related products (including excipients of ATI-2173, tenofovir disoproxil fumarate, and the placebo) as well as severe hypersensitivity reactions (like angioedema) to any drugs
•History of significant cardiovascular, pulmonary, hematologic, neurological, psychiatric, endocrine, immunologic or dermatologic disease
•Presence of clinically significant muscle disorders, myopathies or other forms of liver disease
•Presence of any clinically significant disease, as captured in the medical history or evidence of findings on the physical examination, vital sign assessment and/or ECG assessment, and that would otherwise exclude subject from eligibility in the context of all other listed inclusion and exclusion criteria, as determined by an Investigator

•Positive test result for alcohol and/or drugs of abuse at screening or prior to the first drug administration
•Any history of tuberculosis

•A score greater than F2 (or greater than F3 for HBV/HDV coinfected subjects) on liver biopsy within 12 months prior to screening or at the time of screening
•History of or known presence of hepatocellular carcinoma
•Acute infection or any other clinically significant illness within 14 days of Day 1 of the study
•History of organ transplantation
•Presence of uncontrolled hypertension
•Positive screening results to HIV Ag/Ab combo or hepatitis C virus tests

•Donation of 50 mL or more of blood in the 28 days prior to the first study drug administration
