Eligibility
Key inclusion criteria
Main Inclusion Criteria for All Subjects:

1. Subject has provided written consent.
2. In the investigator's opinion, the subject is able to understand and comply with protocol requirements, instructions, and study restrictions and is likely to complete the study as planned.
3. Subject is in good health as deemed by the investigator, based on the totality of findings following a medical evaluation, including medical history, physical examination, laboratory tests and ECG.
4. Male or female, 18-60 years of age.
5. Body mass index 18-30 kg/m2, inclusive. The minimum weight is 50 kg.
6. A female subject is eligible to participate in this study if she is of non-childbearing potential (defined as females with a documented tubal ligation, bilateral oophorectomy or hysterectomy) or postmenopausal (defined as 12 months of spontaneous amenorrhea and follicle stimulating hormone level within the laboratory's reference range for postmenopausal females). A post-menopausal female receiving hormone replacement therapy who is willing to discontinue hormone therapy 28 days before study drug dosing and agrees to remain off hormone replacement therapy for the duration of the study may be eligible for study participation.
7. If male, subject is surgically sterile or practicing required forms of birth control until 6 months after the last dose of the study drug(s). Males must agree to refrain from sperm donation from check-in through 6 months after the last dose of the study drug(s).
8. Subject has been a nonsmoker and has not used nicotine or nicotine-containing products for at least 6 months.
9. Subjects who participated in Part 1 and/or Part 2 may participate in subsequent Part(s) upon satisfactory completion of a posttreatment visit, 7 days (+2 days) following the subject's last dose, and provided they continue to meet all of the inclusion criteria and none of the exclusion criteria.

Main exclusion criteria:

3. Subject has an estimated creatinine clearance of =80 mL/min based on the Cockcroft-Gault equation; An actual creatinine clearance, as determined by a 24-hour urine collection, may be used in place of, or in conjunction with, the Cockcroft-Gault equation; subjects who have an actual or estimated creatinine clearance within 10% of 80 mL/min may be enrolled in the study at the discretion of the investigator.

6. Subject has a history of malignancy except completely excised basal cell carcinoma or squamous cell carcinoma of the skin.
7. Subject lacks or has poor peripheral venous access.
8. Positive screening result for hepatitis B, hepatitis C and/or HIV serology.
9. Any condition that, in the opinion of the investigator, would compromise the study's objectives or the well-being of the subject or prevent the subject from meeting the study requirements.
10. Clinically significant abnormal ECG findings. Particularly, a history or family history of prolonged QT syndrome (eg, torsade de pointes) or sudden cardiac death.

12. Subject has had major surgery, or clinically significant blood loss or elective blood donation of significant volume (ie, >500 mL) within 60 days of first dose of study drug; >1 unit of plasma within 7 days of first dose of study drug.
13. Abnormal heart rate, respiratory rate, temperature or blood pressure values outside of the normal range (evaluated in a semi-recumbent or recumbent position after 5 minutes of rest). One repeat measurement after an additional 5 minutes of rest is permitted.
14. Evidence of active infection.
15. Unwilling to abstain from alcohol for at least 48 hours prior to the start of dosing through the study completion visit.
16. History of regular alcohol intake >7 units per week of alcohol for females and >14 units per week for males (one unit is defined as 10 g alcohol) within 3 months of the screening visit.
17. The subject has a positive screening or Day -1 drugs of abuse screen.
18. The use of concomitant medications, including prescription, over the counter medications, and herbal medications (such as St. John's Wort [Hypericum perforatum]) within 30 days prior to the first dose of study medication is excluded, unless approved by the Sponsor's Medical Monitor. Occasional use of ibuprofen/paracetamol/ acetaminophen is permitted.
19. Subject has received an investigational drug (including investigational vaccines) or used an invasive investigational medical device within 90 days before the planned study drug.
20. Subject has a history of significant multiple and/or severe allergies, or has had an anaphylactic reaction or significant intolerability to prescription or non-prescription drugs or food.
21. Hypersensitivity to the active substances or to any of the excipients of AL-3778, entecavir or tenofovir disoproxil fumarate.
22. Subject has known allergy to heparin or history of heparin-induced thrombocytopenia.
23. Abnormal biochemistry or hematology laboratory results obtained at screening determined to be clinically significant by the Investigator. Screening ALT, AST, GGT, albumin, and total bilirubin must be within normal ranges. Creatine kinase >1.5 x ULN is exlusionary
24. Unwillingness or inability to comply with the study protocol for any other reason.
