Non-pregnant woman (negative pregnancy test) and not currently breast feeding., 5.

Subjects agree to use acceptable non-hormonal contraceptive methods such as condom, diaphragm, foams, jellies or abstinence for at least 14 days prior to check-in in Period 1 until 14 days after the end of study in Period 2. Female subjects of non-childbearing potential must meet at least one of the following criteria prior to check-in in Period 1: Postmenopausal for at least 1 year or Surgically sterile (bilateral tubal ligation, bilateral oophorectomy or hysterectomy) at least 6 months., 6. Male subjects who are willing or able to use effective contraceptive e.g. condom or abstinence after check-in in Period 1 until 14 days after the end of study in Period 2., 7. Have voluntarily given written informed consent (signed and dated) by the subject prior to participating in this study.
1. History of allergic reaction or hypersensitivity to entecavir or any of the excipients of the product, 2. History or evidence of clinically significant renal, hepatic, gastrointestinal, hematological (e.g. anemia), endocrine (e.g. hyper-/hypothyroid, diabetes), pulmonary or respiratory (e.g. asthma), cardiovascular (e.g. hyper-/hypotension), psychiatric (e.g. depression), neurologic (e.g. convulsant), allergic disease (including drug allergies, but excluding untreated, asymptomatic, seasonal allergies at time of dosing) or any significant ongoing chronic medical illness, 3. Have high risk for coronavirus infection based on risk assessment questionnaire or diagnosed as confirmed case of COVID-19, 4. History about administration of first dose or second dose of COVID-19 vaccine within 30 days prior to check-in in each Period., 5. History or evidence of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption, 6. History of problems with swallowing tablet or capsule, 7. History of sensitivity to heparin or heparin-induced thrombocytopenia, 8. Any condition possibly affecting drug absorption e.g. gastrectomy, enterectomy, gastritis or duodenal or gastric ulceration other than appendectomy, 9. History of vomiting or diarrhea within 24 hours prior to check-in in each period, 10. History or evidence of drug addict or investigation with urine sample shows a positive test for drug of abuse (morphine, marijuana or methamphetamine), 11. 12-lead ECG demonstrating QTc more than 450 msec, a QRS interval more than 120 msec or with an abnormality considered clinically significant at screening. If QTc exceeds 450 msec, or QRS exceeds 120 msec, the ECG will be repeated two more times and the average of the three QTc or QRS values will be used to determine the subjects eligibility., 12. Investigation with blood sample shows positive test for HBsAg., 13. Abnormal liver function, more than or equal to 1.5 times of upper normal limit of reference range for ALT, AST or bilirubin levels at screening laboratory test, 14. History or evidence of habitual use of tobacco or nicotine containing products and cannot abstain for at least 48 hours prior to check-in in Period 1 and continued for entire duration of the study, 15. History or evidence of alcoholism or harmful use of alcohol (less than 2 years) i.e., alcohol consumption of more than 14 standard drinks per week for men and 7 standard drinks per week for women (A standard drink is defined as 360 mL of beer or 150 mL of wine or 45 mL of 40% distilled spirits, such as rum, whisky, brandy etc.), 16.

In case of alcohol breath test result represents the alcohol concentration range of 1 - 10 mg% BAC and the physician carefully considers that the value came from other reasons, not from the alcohol drinking behavior of subjects, the test will be repeated two times separately, not more than 10 minutes. The result of the last time should be used for subjects eligibility which must be 0 mg%BAC., 17.
