Racial/Ethnic Groups
  • There are no significant racial differences in entecavir pharmacokinetics. The safety and efficacy of Baraclude 0.5 mg once daily were assessed in a single-arm, open-label trial of HBeAgpositive or -negative, nucleoside-naïve, Black/African American (n=40) and Hispanic (n=6) subjects with chronic HBV infection.

The trial population was 82% male, 39% Caucasian, and 37% Asian, with a mean age of 49 years; 89% of subjects had
