Overview

Brief Summary

The OPTION2 trial (randomized controlled trial of IndObufen versus asPirin after coronary drug-eluting stent implantaTION in elderly patients with acute coronary syndrome) was designed to compare the 1-year clinical efficacy and safety of indobufen-based dual antiplatelet therapy (DAPT) (indobufen 100mg bid plus ticagrelor 90mg bid) or conventional DAPT (aspirin 100mg qd plus ticagrelor 90mg bid) in acute coronary syndrome (ACS) patients aged over 65 years old undergoing coronary drug-eluting stent (DES) implantation.

Arms & Interventions

indobufen plus ticagrelor

Experimental

Patients meeting the criteria are randomized before discharge from the hospital and given indobufen 100 mg bid and ticagrelor 90mg bid the second day after randomization. The administration shall last 12 months.

Intervention: Indobufen (Drug)

indobufen plus ticagrelor

Experimental

Patients meeting the criteria are randomized before discharge from the hospital and given indobufen 100 mg bid and ticagrelor 90mg bid the second day after randomization. The administration shall last 12 months.

Intervention: Ticagrelor (Drug)

aspirin plus ticagrelor

Active Comparator

Patients meeting the criteria are randomized before discharge from the hospital and continued aspirin 100 mg qd and ticagrelor 90mg bid. The administration shall last 12 months.

Intervention: Aspirin (Drug)

aspirin plus ticagrelor

Active Comparator

Patients meeting the criteria are randomized before discharge from the hospital and continued aspirin 100 mg qd and ticagrelor 90mg bid. The administration shall last 12 months.

Intervention: Ticagrelor (Drug)

Outcomes

Primary Outcomes

  • a composite endpoint of CV death, nonfatal MI, ischemic stroke, definite or probable ST, or BARC criteria type 3 or 5 bleeding(1-year)
  • a composite of CV death, nonfatal MI, ischemic stroke, definite or probable ST(1-year)
  • all-cause mortality(1-year)
