The Medicines Company Completes Clevidipine Phase III Safety Trials and Initiates Phase III Severe Hypertension Trial

ECLIPSE Enrollment Complete, First Patient Enrolled in VELOCITY

PARSIPPANY, N.J.--(HSMN NewsFeed)--Sept. 11, 2006--The Medicines Company (NASDAQ: MDCO ) today provided an update of Phase III clinical trials of clevidipine, an intravenous, ultrashort-acting calcium channel blocker intended for the treatment of severely-elevated blood pressure in the hospital setting when oral therapy is not feasible or desirable. Investigators have completed patient enrollment and follow-up of the ECLIPSE trials, a series of safety evaluations in the perioperative treatment of hypertension. The Company also announced initiation of the VELOCITY trial in patients with severely-elevated blood pressure who are presenting to the Emergency Department or Intensive Care Unit.

VELOCITY is a multi-center, single arm, open-label Phase III clinical trial in 100 patients with severe hypertension. The objective is to evaluate the safety of a titration dosing regimen of an intravenous infusion of clevidipine given continuously for at least 18 hours. The trials' co-principal investigators are Charles V. Pollack, MD, Chairman, Department of Emergency Medicine, at Pennsylvania Hospital and Frank Peacock, MD, Vice Chairman, ED Research, The Cleveland Clinic.

"Many of the patients treated in emergency situations have severely-elevated blood pressure that we need to bring down quickly," said Dr. Peacock. "The ideal antihypertensive drug in the hospital setting would act rapidly to reduce blood pressure to a desired range and go away rapidly to allow for fast and easy transition to an oral agent. Our patients are acutely ill with several co-morbidities and may need treatment for long durations -- even several days. In VELOCITY, we will evaluate clevidipine safety in a wide range of emergent patient types."

Two Phase III efficacy trials known as ESCAPE were completed previously and met their objectives. The three ECLIPSE studies compared clevidipine to active comparators; nitroglycerin, sodium nitroprusside, and nicardipine. The Company expects to review the completed ECLIPSE data in the fourth quarter of 2006. If these trials meet their objectives, The Medicines Company anticipates submitting an application for clevidipine U.S. marketing approval in the first half of 2007. The submission would include data from six Phase III safety and efficacy trials, including VELOCITY.

If approved for marketing, clevidipine would be the first of a third generation of intravenous dihydropyridine calcium channel blockers. It acts by selectively relaxing the smooth muscle cells that line small arteries, resulting in widening of the artery and reduction of blood pressure with minimal effect on the heart rate.

John Kelley, The Medicines Company's President and Chief Operating Officer, stated, "We expect clevidipine to be a cornerstone of our acute hospital care franchise. With the achievement of these milestones, we remain on track with our Phase III development goals."
