Rolofylline Did Not Demonstrate Efficacy For Acute Heart Failure In Clinical Trial

Merck & Co., Inc. said that preliminary results for the pivotal Phase III study of rolofylline (MK-7418), the Company's investigational medicine for the treatment of acute heart failure, show that rolofylline did not meet the primary or secondary efficacy endpoints. While Merck will continue to analyze the data with outside experts, the Company will not file applications for regulatory approval this year. The results from this study will be presented at a medical meeting later this year.
