Summary

The ELECTRA-SIRIO 2 study is a randomized, multicenter, double-blind, investigator-initiated clinical trial aimed to evaluate safety and efficacy of two ticagrelor-based de-escalation antiplatelet strategies in patients with acute coronary syndrome (ACS). During the hospitalization due to ACS, participants will be randomized in a 1:1:1 ratio into one of three arms: low-dose ticagrelor with aspirin (LDTA), low-dose ticagrelor with placebo (LDTP), and standard-dose ticagrelor with aspirin (SDTA), the latter being the control arm. Up to day 30, all enrolled patients will receive standard-dose ticagrelor (2x90mg) + aspirin (1x100mg). Starting from day 31 LDTA and LDTP patients will receive low-dose ticagrelor (2x60mg) + aspirin (1x100mg), SDTA - continuation of previous treatment. Starting from day 91 LDTP patients will receive low-dose ticagrelor (2x60mg) + placebo, SDTA and LDTA - continuation of previous treatment. The aim of the study is to evaluate the influence of ticagrelor maintenance dose reduction from 2x90mg to 2x60mg with or without continuation of aspirin versus dual antiplatelet therapy with standard dose ticagrelor in reducing clinically relevant bleeding and maintaining anti-ischemic efficacy in ACS patients.
