Study Endpoints

Primary Endpoints

Number of Participants With First Occurrence of Any Event in the Composite of Major Coronary Events During the Time Period for Follow-up (FU) of Cardiovascular (CV) Event
From randomization until the End-of-Treatment visit or the last date on which endpoints were able to be assessed (up to 3.80 years)

Coronary heart disease (CHD) death=occurrence of a fatal myocardial infarction (MI), death caused by documented cardiac arrest, death resulting from heart failure in a participant with known CHD, death from other forms of acute/chronic CHD, unwitnessed death of unknown origin, or sudden death. Acute MI=evidence of myocardial necrosis in a clinical setting consistent with myocardial ischemia. Prior MI diagnosed post-randomization (e.g., silent MI)=the development of new pathological Q waves with/without symptoms OR imaging evidence of a region of loss of viable myocardium that is thinned and fails to contract, in the absence of a nonischemic cause (pre-event imaging data required for verification of new abnormality), OR pathological findings of a healed/healing MI. Urgent coronary revascularization (CR) for MI=ischemic discomfort at rest that prompted CR during the same hospitalization or resulted in hospital transfer for the purpose of CR.

From randomization until the End-of-Treatment visit or the last date on which endpoints were able to be assessed (up to 4.25 years/average of 3.51 years)

CV death=death due to a CV cause, which included but was not limited to deaths resulting from stroke, arrhythmia, sudden death (witnessed/unwitnessed), MI, heart failure, pulmonary embolism, peripheral arterial disease, or complications of a CV procedure. Deaths not clearly attributable to non-CV causes are considered to be CV deaths. Acute MI=evidence of myocardial necrosis in a clinical setting consistent with myocardial ischemia. Prior MI diagnosed post-randomization (e.g., silent MI)=the development of new pathological Q waves with/without symptoms OR imaging evidence of a region of loss of viable myocardium that is thinned and fails to contract, in the absence of a non-ischemic cause (pre-event imaging data required for verification of new abnormality), OR pathological findings of a healed/healing MI. Stroke=presence of a new focal neurologic deficit thought to be of vascular origin, with signs/symptoms lasting \>24 hours or results in death (in \<24 hours).

Frequently asked questions about Darapladib

What is Darapladib used for?

Darapladib is an investigational small molecule being developed for cardiovascular conditions, specifically Acute Coronary Syndrome, Diabetic Retinopathy, and Atherosclerosis. It is a Phase 3 drug, meaning it has advanced to late-stage clinical testing but is not yet approved. GSK plc (GSK) is the developer.

Who makes Darapladib?

Darapladib is being developed by GSK plc, a global pharmaceutical company traded on the London Stock Exchange under the ticker GSK. The drug is a small molecule in Phase 3 clinical development for cardiovascular indications including Acute Coronary Syndrome and Atherosclerosis.

What phase is Darapladib in?

Darapladib is in Phase 3 clinical development. It is an investigational drug, not yet approved by regulatory authorities. The drug has completed 11 clinical trials with a total enrollment of 16,091 participants, all of which were randomized, double-blind, and placebo-controlled.

What clinical trials has Darapladib been in?

Darapladib has completed 11 clinical trials. Notable ones include NCT00411073, a Phase 1 study on its effects on heart electrical conduction in 72 participants, and NCT00743860, a pharmacokinetic study in 20 healthy volunteers. Other trials include NCT01154114 in hepatically impaired subjects and NCT01873339 on drug interactions.

Is Darapladib the same as SB-480848?

Yes, Darapladib is also known as SB-480848. Clinical trial records reference both names, such as NCT00411073, which is titled 'Study Of The Effects Of SB 480848 (Darapladib) On The Electrical Conduction Of The Heart.' This alternative name appears in early-stage trials conducted in the United States.
