Additional Information

CVT-6883, a selective A2B adenosine antagonist, represents a novel potential approach to treating cardiopulmonary diseases. A pre-clinical study showed that CVT-6883 significantly reduced elevated markers of inflammation, fibrosis and pulmonary injury in in vivo preclinical models. An initial Phase 1 study of CVT-6883 has been completed. In this randomized, double-blind, placebo-controlled, single ascending dose study in 24 healthy volunteers, CVT-6883 was well tolerated with no serious adverse events reported. In 2007, we completed a second Phase 1 trial, an ascending, multi-dose study in 30 healthy volunteers.
On November 02, 2007, CV Therapeutics, Inc. announced that data from a randomized, single-blind, placebo-controlled, multiple ascending dose Phase 1 study of CVT-6883, a potentially first in class adenosine A2B antagonist, show that a range of doses were safe and well tolerated in 30 healthy volunteers.
