US drugmaker Gilead Sciences' darusentan showed signifcant reductions in blood pressure when added to existing antihypertensive regimens in a very difficult-to-treat patient population, according to data presented at the 2009 annual meeting of the American Society of Hypertension, in San Francisco.
The once-daily oral endothelin receptor antagonist is one of the key drug candidates set to help the firm diversify its portfolio away from its current focus on antivirals. The agent yielded mean reductions in trough sitting systolic BP from baseline of 16.5mmHg, 18.1mmHg, 18.1mmHg and 8.6mmHg for the darusentan 50mg, 100mg, 300mg and placebo groups, respectively, after 14 weeks of treatment.
