Main Study (CACZ885M2301): The purpose of the pivotal phase of this trial was to test the hypothesis that canakinumab treatment of patients with myocardial infarction (MI) at least one month prior to study entry and elevated hsCRP could prevent recurrent cardiovascular events. The purpose of the extension phase of the main study is to collect additional long-term safety data on continued exposure to canakinumab in patients who participated in the pivotal phase. Sub-study 1 (CACZ885M2301S1): The purpose of this sub-study was to evaluate the effect of quarterly subcutaneous canakinumab treatment for 24 months comparted with placebo on the carotid plaque burden measured by integrated vascular MRI in patients enrolled in the CACZ885M2301 study (CANTOS). Sub-study 2 (CACZ885M2301S2): The purpose of this CANTOS sub-study was to determine whether, in patients with type 2 diabetes participating in the CANTOS main study, canakinumab compared to placebo, on top of standard of care could increase insulin secretion and insulin sensitivity.

Official Title

A Randomized, Double-blind, Placebo-controlled, Event-driven Trial of Quarterly Subcutaneous Canakinumab in the Prevention of Recurrent Cardiovascular Events Among Stable Post-myocardial Infarction Patients With Elevated hsCRP


Sub-study 1 and 2 were terminated prior to data collection from subjects. However, there is an ongoing extension trial where patients are receiving open-drug label.
