Gilead Sciences received a major pipeline setback with disappointing results from a phase III trial of darusentan in which it failed to achieve its primary endpoint.
The drug was being studied under an international clinical trial (DAR-312) for the treatment of resistant hypertension. As a result of the setback, Gilead is considering the option of dropping the program so that its resources can be utilized for other potential candidates rather than conducting another intensive phase III study.

Gilead Sciences has filed an appeal in the Indian Intellectual Property Appellate Board (IPAB) to challenge a recent order by an Indian Patent Office that rejected two patent claims for its best seller drug Viread (tenofovir disoproxil fumarate).
In August, the Indian Patent Office in Delhi rejected two patents sought by the firm for Viread after patient groups and Indian company Cipla challenged its patentability.

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.
