Overview

The purpose of this study is to measure the change in high-sensitivity C-reactive protein (hsCRP), a marker of inflammation in the body, with clazakizumab compared with placebo in adults who have elevated hsCRP and at increased risk for cardiovascular event.

Participation in the study will last about 9 months.

  • Type 2 diabetes
  • Hypertension
  • Chronic kidney disease Grade 3 or 4

Exclusion Criteria:

• Acute cardiovascular event within 60 days prior to screening
• Acute decompensated heart failure hospitalization within 60 days prior to screening
• Planned coronary revascularization (percutaneous coronary intervention or coronary artery bypass grafting) or major surgery at the time of randomization
• New York Heart Association Class III or IV heart failure

• History of diverticular disease, gastrointestinal perforation, or major gastrointestinal surgery
• Mechanical heart valve prosthesis requiring chronic vitamin K antagonist anticoagulation
• Use of colchicine within 14 days prior to screening or anticipated need during the study
• Use of immunosuppressive or immunomodulatory agents, including other biologic anti-IL-6 therapies, within specified windows prior to screening
