Gilead Sciences (GILD)

Gilead Sciences today announced the presentation of three-year (144-week) open label data from two pivotal Phase III clinical trials, Studies 102 and 103, evaluating the safety and efficacy of once-daily Viread® (tenofovir disoproxil fumarate) among adult patients with chronic hepatitis B virus (HBV) infection.
These new data show that the majority of patients who received Viread for up to 144 weeks experienced sustained suppression of HBV DNA levels in the blood to below 400 copies/mL (87 percent in Study 102 and 71 percent in Study 103). Additionally, cumulatively over 144 weeks, 8 percent of all patients in Study 103 (HBeAg-positive) experienced “s” antigen (HBsAg) loss, which can contribute to resolution of chronic hepatitis B infection. Notably, no mutations associated with resistance to Viread developed in any patients up to 144 weeks of treatment.
