The Medicines Company Discontinues Phase 3 CHAMPION Clinical Trial Program of Cangrelor

Interim Analyses Indicate CHAMPION Program Will Not Meet Efficacy Endpoints

Company to Continue and Accelerate Phase 2/3 Studies of Cangrelor in Settings Where Oral Drugs Cannot Be Used or Short Half-Life Is Desirable

PARSIPPANY, NJ--(Healthcare Sales & Marketing Network)--May 13, 2009 -- The Medicines Company (NasdaqGS:MDCO ) today announced that it is discontinuing its Phase 3 CHAMPION clinical trial program of cangrelor in patients undergoing percutaneous coronary intervention (PCI).

The program's independent Interim Analysis Review Committee (IARC), after conferring with the Drug Safety Monitoring Board, reported to the Company that the CHAMPION-PLATFORM trial would not meet the goal of demonstrating persuasive evidence of clinical effectiveness that could form the basis for regulatory approval. This placebo-controlled trial compared treatment with cangrelor (in combination with usual care) to usual care in patients who require PCI.

The IARC also reported to the Company that, based on updated information, the CHAMPION-PCI trial, a clinical trial comparing treatment with cangrelor to clopidogrel (600 mg loading dose) in patients who require PCI, showed no significant differences in measures of clinical effectiveness.

Safety findings for the program were consistent with those expected from short-term P2Y12 platelet inhibition and included an increase in minor bleeding among patients given cangrelor in comparison to placebo, but not in comparison to clopidogrel.

Based on the totality of these data, the IARC has recommended that enrollment in both trials be discontinued and that all remaining data should be collected and analyzed. The Company is in the process of notifying the investigators and regulatory agencies of the discontinuation of the CHAMPION program.

The IARC also recommended that the Company should consider focusing on short-term use of cangrelor in settings where oral drugs cannot be used or when a short half-life is highly desirable. The Company had previously begun studying cangrelor in such a setting. This research, known as the BRIDGE study aims to establish the dosage of cangrelor that achieves greater than or equal to 60% inhibition of platelet aggregation for five days. The Company plans to enroll approximately 200 patients who discontinue clopidogrel in preparation for cardiac surgery. The aim is to show safe "bridging" of patients during the pre- and post-surgical period of risk. If successful, this approach may form the basis for subsequent regulatory filings.

"We are disappointed that the CHAMPION program has not provided sufficient evidence of the clinical effectiveness of cangrelor to warrant completion of these Phase 3 trials. We thank the Investigators and oversight Committees for their work and we will follow their guidance. The trials are being discontinued; we plan to finalize data collection and analyses, and we expect that the data will be presented at a major cardiology meeting in due course. We will now move forward more quickly with our studies where cangrelor is tested to enable safe 'bridging' of patients undergoing surgery. In this setting of high unmet medical need, long-term clopidogrel is often discontinued at considerable risk to patients. The rapid onset, offset and titratable anti-platelet pharmacology of cangrelor seems ideally suited for this potential use. The development of cangrelor will therefore continue," said Clive Meanwell, M.D., Ph.D., Chief Executive Officer of The Medicines Company.

"Looking longer term, it is important to note that The Medicines Company is not dependent on a single product. We have a diversified portfolio of current and pipeline products, industry-leading operational capabilities and we are cash flow positive. We believe the Company is well positioned to deliver future growth and long-term shareholder value. We remain committed to our strategy of building a leading global critical care hospital medicines business. We will continue to focus on our market-leading Angiomax product, the Angiox business, the ongoing Cleviprex launch in the United States and international Cleviprex regulatory filings now underway, advancing Phase 3 trials of oritavancin and on our early stage development program with CU2010," he continued.

The Company noted that the discontinuation of the CHAMPION program will result in cost savings of approximately $5 million in 2009.


Cangrelor is an investigational intravenous Antiplatelet Agent exclusively licensed in December 2003 from AstraZeneca.

The Phase 3 program for cangrelor consisted of two large studies with a combined planned total enrollment of 15,400 patients. The CHAMPION-PCI study, which commenced enrollment in March 2006, enrolled 98% of the patients out of a planned target of 9,000 patients. The objective of this study was to demonstrate that the efficacy of cangrelor is superior, or at least non-inferior, to that of clopidogrel in subjects requiring PCI as measured by a composite of all-cause mortality, myocardial infarction (MI), and ischemia driven revascularization (IDR) at 48 hours after PCI. The second trial in the Phase 3 program, referred to as CHAMPION-PLATFORM, commenced enrollment in October 2006 and enrolled 83% of the planned target of 6,400 patients. The objective of this study was to demonstrate that the efficacy of cangrelor (combined with usual care) is superior to that of usual care, in subjects requiring PCI, as measured by a composite of all-cause mortality, MI, and IDR.

In both studies, the incidence of hemorrhage by clinically relevant criteria (ACUITY, GUSTO, TIMI) and the need for blood transfusions was also measured up to 48 hours.
