This study will test whether darapladib can safely lower the chances of having a cardiovascular event (such as a heart attack or stroke) when treatment is started within 30 days after an acute coronary syndrome (also called ACS).

Drug: Darapladib 160 mg
Drug: Placebo
Phase 3

Study Design: Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Clinical Outcomes Study of Darapladib Versus Placebo in Subjects Following Acute Coronary Syndrome to Compare the Incidence of Major Adverse Cardiovascular Events (MACE).

Primary Outcome Measures:
  • Time to the first occurrence of any component of the composite of Major Adverse Cardiovascular Events [MACE: CV death (death due to a cardiovascular cause), non-fatal myocardial infarction, non-fatal stroke]. [ Time Frame: Through the end of the study. ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • The composite measure of major coronary events that include the first occurrence of coronary heart disease death, non-fatal myocardial infarction or urgent coronary revascularization for myocardial ischemia. [ Time Frame: Through the end of the study. ] [ Designated as safety issue: No ]
  • The composite measure of total coronary events that include the first occurrence of coronary heart disease death, non-fatal MI, hospitalization for UA, or any coronary revasc procedure (excluding PCI planned prior to but performed after randomization). [ Time Frame: Through the end of the study. ] [ Designated as safety issue: No ]
  • The individual components of MACE [cardiovascular death, myocardial infarction (fatal and non-fatal), stroke (fatal and non-fatal)]. [ Time Frame: Through the end of the study. ] [ Designated as safety issue: No ]
  • The first occurrence of any component of the composite of all-cause mortality, non-fatal myocardial infarction, or non-fatal stroke. [ Time Frame: Through the end of the study. ] [ Designated as safety issue: No ]
  • All cause mortality. [ Time Frame: Through the end of the study. ] [ Designated as safety issue: No ]

Arms Assigned Interventions
Experimental: Darapladib 160 mg
Single daily oral tablet
Drug: Darapladib 160 mg
Lp-PLA2 inhibitor administered in addition to standard therapy.
Other Name: SB-480848
Placebo Comparator: Placebo
Single daily oral tablet

Placebo administered in addition to standard therapy.

Detailed Description:

Subjects who qualify for the study will be randomized 1:1 to either darapladib or placebo administered in addition to standard therapy. Following the baseline visit, subjects will be expected to return for clinic visits at 1 month, 3 months, 6 months and every 6 months until the end of the study.


Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Signed written informed consent.
  • Men or women at least 18 years old (in Taiwan, at least 20 years old). Women must be post-menopausal or using a highly effective method for avoidance of pregnancy.
  • Hospitalization for acute coronary syndrome (ACS) within 30 days prior to study entry.
  • Clinically stable for 24 hours prior to study entry.
  • A planned percutaneous coronary intervention (PCI) should be performed prior to study entry, whenever possible.
  • At least one of the following:
  • At least 60 years old.
  • Myocardial infarction prior to the qualifying ACS event.
  • Diabetes mellitus requiring treatment with medication.
  • Diagnosed mild or moderate reduction in kidney function.
  • Cerebrovascular disease (carotid artery disease or ischemic stroke more than 3 months prior to study entry) OR peripheral artery disease.

Exclusion Criteria:

  • ACS symptoms or lab results not believed to be caused by a narrowing or blocked coronary artery.
  • No major coronary artery with a blockage of more than 50% (unless all stenoses are successfully treated by PCI).
  • Planned coronary artery bypass graft (CABG) surgery, or CABG surgery performed after the qualifying ACS event and prior to study entry.
  • Certain types of liver disease.
  • Severe reduction in kidney function OR removal of a kidney OR kidney transplant.
  • Severe heart failure.
  • Blood pressure higher than normal despite lifestyle changes and treatment with medications.
  • Any life-threatening disease with a life expectancy of less than 2 years (other than heart disease) that may prevent the subject from completing the study.
  • Severe asthma that is poorly controlled with medication.
  • Pregnancy (Note: A pregnancy test will be performed on all non-sterile women prior to study entry).
  • Previous severe allergic reaction to food, medications, drink, insect stings, etc.
  • Drug or alcohol abuse within the past 6 months. Mental/psychological impairment that may prevent the subject from complying with study procedures or understanding the goal and potential risks of participating in the study.
  • Certain medications that may interfere with the study medication (these will be identified by the study doctor).
  • If both birth parents are at least 50% Japanese, Chinese, or Korean ancestry, must have a blood sample collected for Lp-PLA2 activity. Those with Lp-PLA2 activity less than or equal to 20.0 nmol/min/mL are excluded.
  • Previously took darapladib (SB-480848).
  • Participation in a study of an investigational medication within the past 30 days.
  • Current participation in a study of an investigational device.
  • Any other reason the investigator deems the subject should not participate in the study.
