A Study to Evaluate the Safety of Apixaban in Acute Coronary Syndrome (ACS) Japanese Patients
Overview[ - collapse ][ - ]
Purpose | The purpose of this study is to assess the bleeding safety (the composite endpoint of major and clinically relevant non-major bleeding) of 2 doses of apixaban (2.5 mg BID and 5.0 mg BID) or placebo in combination with standard therapy (aspirin and /or additional antiplatelet therapy) over a 24 week treatment period in selected subjects with recent (≤7 days) acute coronary syndrome. |

Current Primary Outcome Measures | Percentage of Participants Who Had Composite of International Society on Thrombosis and Haemostasis (ISTH)-Defined Major and Clinically-relevant Non-major (CRNM) Bleeding Events Occurring During the Treatment Period. [Time Frame: Week 0 to Week 24] [Designated as safety issue: Yes]Major bleeding event was acute clinically overt bleeding accompanied by decrease in hemoglobin of 2 g/dL or more over a 24-hour period, transfusion of 2 or more units of packed red blood cells, or bleeding that occurs in critical site (e.g., intracranial). Fatal bleeding was also major bleeding event. CRNM bleeding was acute or sub-acute clinically overt bleeding that did not satisfy the criteria for major bleeding and that led to either hospital admission for bleeding, physician guided medical or surgical treatment for bleeding or a change in antithrombotic therapy. |

Official Title | A Phase 2, Placebo-Controlled, Randomized, Double-Blinded, Multicenter, Study To Evaluate The Bleeding Profile Of 2.5 Mg And 5.0 Mg BID Apixaban In Combination With Standard Therapy In Patients With Recent (≤7 Days) Acute Coronary Syndrome (ACS) |
Brief Summary | The purpose of this study is to assess the bleeding safety (the composite endpoint of major and clinically relevant non-major bleeding) of 2 doses of apixaban (2.5 mg BID and 5.0 mg BID) or placebo in combination with standard therapy (aspirin and /or additional antiplatelet therapy) over a 24 week treatment period in selected subjects with recent (≤7 days) acute coronary syndrome. |
Detailed Description | Due to withdraw of global phase 3 study (APPRAISE-2) for safety issue, B0661004 Data monitoring committee (DMC) also recommended terminating this study. Therefore, Pfizer decided to stop this study. |
