Brief Summary
To prove that a study drug is noninferior to a control drug with a proportion of subjects who showed HBV DNA undetected (less than 400 copies/mL (69 IU/mL)) at the 48th week after 48-week administration of Besifovir 150 mg, or Tenofovir 300 mg as a control drug to chronic hepatitis B patients
