According to 2009 data from the Organisation for Economic Co-operation and Development (OECD), more than 2.5 million PCIs are performed globally per year. Treatment guidelines in the United States and Europe recommend stent patients receive oral P2Y12 inhibitors for up to 12 months following percutaneous coronary intervention (PCI). It is estimated that up to 25 percent of these patients with stents in place will require a surgical procedure during the first five years after PCI.
Dimitrios Goundis, PhD, head of R&D at The Medicines Company added, "With strong patient enrollment in the Phase 3 PHOENIX trial of cangrelor in PCI patients and these results from the BRIDGE trial, there is great momentum with the cangrelor program, which is an important part of our portfolio of acute and intensive care hospital compounds."
Summary methods and results
The first stage of BRIDGE identified the cangrelor dose that maintains a 'thienopyridine-like' level of platelet inhibition. The second stage reported today was a prospective, randomized, double-blind, placebo-controlled trial in 210 patients with an acute coronary syndromes (ACS) or treated with a coronary stent (bare metal stent or drug eluting stent) on a thienopyridine awaiting coronary artery bypass grafting (CABG). After thienopyridine discontinuation (<72 hours), patients were administered cangrelor or placebo for at least 48 hours and up to 7 days, which was discontinued 1-6 hours prior to CABG. The objective was to demonstrate that a cangrelor IV infusion would maintain levels of platelet reactivity <240 P2Y12 Reaction Units (PRU) throughout the pre-operative period as measured by a P2Y12 assay. Platelet inhibition results are shown in this press release:
