The ASCEND study was a large, international trial that aimed to assess the effects of avosentan on diabetic nephropathy. To the disappointment of the nephrology community who had anticipated that the trial would demonstrate beneficial effects of this treatment, ASCEND was terminated early owing to excessive rates of adverse events, such as congestive heart failure associated with avosentan use.
