CARY, N.C., Jan. 25, 2022 (GLOBE NEWSWIRE) -- Chiesi USA (key-ay-zee), the U.S. affiliate of Chiesi Farmaceutici, an international research-focused healthcare Group (Chiesi Group), today announced the new publication of a post hoc analysis of the CHAMPION PHOENIX clinical trial that evaluated the timing, number and type of early cardiovascular events that occurred with treatment of KENGREAL® (cangrelor) compared to clopidogrel in patients undergoing PCI. The analysis is published in Circulation: Cardiovascular Interventions, a journal of the American Heart Association, and can be accessed here. The overall trial results of CHAMPION PHOENIX showing a significant benefit in the primary endpoint and key secondary endpoint were previously published in the New England Journal of Medicine and can be accessed here.
Patients undergoing PCI are at risk of thrombotic complications. KENGREAL is the only intravenous P2Y12 platelet inhibitor indicated as an adjunct to PCI to reduce the risk of periprocedural myocardial infarction (MI), repeat coronary revascularization, and stent thrombosis (ST) in patients who have not been treated with a P2Y12 platelet inhibitor and are not being given a glycoprotein IIb/IIIa inhibitor.
The current post hoc analysis found that in the first two hours post-randomization, KENGREAL significantly decreased the primary composite endpoint of death, MI, ischemia-driven revascularization (IDR) or ST by 25% when compared with clopidogrel (4.1% vs 5.4%; hazard ratio, 0.76 [95% CI, 0.64–0.90], p=0.002). Similar findings were seen when evaluating the secondary composite endpoint of death, Society of Coronary Angiography and Intervention (SCAI)-defined MI, IDR, or Academic Research Consortium (ARC)-defined ST at two hours (0.9% vs. 1.6%; hazard ratio 0.57 [95% CI, 0.40–0.80], p=0.001). There was no rebound increase in cardiovascular events during the time period in which patients were transitioned from KENGREAL to an oral P2Y12 inhibitor.
The majority of cardiovascular events (63%) as defined within the secondary composite endpoint occurred within two hours after randomization, supporting prior findings of the increased risk of ischemic events in the early time period around PCI. The most common early event was SCAI-MI (44%), followed by ARC-ST (7%), IDR (7%) and death (5%).
“These data add to the main results as well as multiple prior analyses from CHAMPION PHOENIX demonstrating the efficacy of cangrelor in reducing important ischemic events, in particular in the early period of PCI when patients are at the highest risk of complications,” stated study co-chair Deepak L. Bhatt, MD, MPH, Executive Director of Interventional Cardiovascular Programs at Brigham and Women’s Hospital and Professor of Medicine at Harvard Medical School. “These results further strengthen the case for using cangrelor in appropriate PCI patients,” added study co-chair Robert A. Harrington, MD, Chairman of Medicine and Arthur L. Bloomfield Professor of Medicine at Stanford University.
“These results demonstrate the importance of potent platelet inhibition during this critical window of treatment,” said Martin Marciniak, Vice President and Head of U.S. Medical Affairs at Chiesi. “We are thankful for the contributions of everyone who participated in this valuable analysis, and we’re committed to supporting advancements in interventional cardiology to improve care for cardiac patients.”
CHAMPION PHOENIX was a randomized, double-blind, placebo-controlled phase III trial part of a clinical development program that established the efficacy and safety of KENGREAL. The trial consisted of 11,145 patients undergoing either urgent or elective PCI and were receiving guideline-recommended therapy. Patients being treated with KENGREAL received a bolus followed by an infusion for two hours or for the duration of the procedure, whichever was longer. Patients received a loading dose of 600mg or 300mg of clopidogrel at the end of the infusion. The trial found that KENGREAL reduced the primary composite endpoint of death, MI, IDR, or ST at 48 hours in patients undergoing PCI, as well as the key secondary endpoint of ST.
This analysis presents findings that supplement the predefined, primary result of the CHAMPION PHOENIX trial. The CHAMPION PHOENIX trial was not designed to examine the impact of KENGREAL versus clopidogrel in the first two hours post-randomization. This analysis also characterizes a post hoc secondary composite endpoint described earlier that was not part of the original trial design.
Treatment protocols should account for individualization of care as KENGREAL may not be appropriate for some patients.
KENGREAL® (cangrelor) for Injection is a P2Y12 platelet inhibitor indicated as an adjunct to percutaneous coronary intervention (PCI) to reduce the risk of periprocedural myocardial infarction (MI), repeat coronary revascularization, and stent thrombosis (ST) in patients who have not been treated with a P2Y12 platelet inhibitor and are not being given a glycoprotein IIb/IIIa inhibitor.
Important Safety Information
KENGREAL® (cangrelor) for Injection is contraindicated in patients with significant active bleeding.
KENGREAL® is contraindicated in patients with known hypersensitivity (e.g., anaphylaxis) to cangrelor or any component of the product.
Drugs that inhibit platelet P2Y12 function, including KENGREAL®, increase the risk of bleeding. In CHAMPION PHOENIX, bleeding events of all severities were more common with KENGREAL® than with clopidogrel. Bleeding complications with KENGREAL® were consistent across a variety of clinically important subgroups. Once KENGREAL® is discontinued, there is no antiplatelet effect after an hour.
The most common adverse reaction is bleeding.
