ClinicalTrials.gov Identifier:
NCT01245634
First received: November 19, 2010
Last updated: July 29, 2013
Last verified: July 2013
  Purpose

This randomized double-blind, placebo-controlled study will evaluate the efficacy and safety of RO4905417 in the prevention of saphenous vein graft disease in patients undergoing elective or urgent coronary artery bypass (CABG) surgery. Patients will be randomized to receive either RO4905417 20 mg/kg by intravenous infusion or placebo every 4 weeks for 32 weeks.

Primary Outcome Measures:
  • Proportion of patients with diameter stenosis >50% (including total occlusion) of at least one saphenous vein graft, as assessed by invasive angiography [ Time Frame: 1 year ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Lumen diameter of saphenous vein grafts, as assessed by invasive angiography [ Time Frame: 1 year ] [ Designated as safety issue: No ]
  • Proportion of patients needing revascularization [ Time Frame: 1 year ] [ Designated as safety issue: No ]
  • Safety: Incidence of adverse events (including major adverse cardiovascular events) [ Time Frame: 1 year ] [ Designated as safety issue: No ]
