403-P: Impact of Diabetes-Related Factors and Background Antihyperglycemic Therapy on the Efficacy and Safety of Ticagrelor Added to Aspirin: Insights from the THEMIS Trial

In the THEMIS trial of 19,220 patients with stable CAD and T2DM without prior MI or stroke followed for a median of 39.9 months, ticagrelor plus aspirin (ASA) lowered ischemic CV events but increased major bleeding events compared with placebo plus ASA, with a more favorable net clinical benefit in those with prior PCI. We now report the efficacy and safety by diabetes-related factors and background antihyperglycemic therapy. While the incidence of the primary efficacy outcome (CV death, MI, stroke; MACE) event rates (overall 8.1%) was higher with increasing diabetes duration (11.1% >20 years vs. 6.7% ≤5 years) and A1c (11.8% >10% vs. 6.4% ≤6%), the relative benefits of ticagrelor on MACE reduction (overall HR 0.90; p=0.04) did not differ across these various subgroups (p-values for interaction=0.83 and 0.16, respectively). In contrast, the primary safety outcome (TIMI major bleeding) event rate (overall 1.6%) did not vary by diabetes duration or A1c and was similarly increased by ticagrelor in all of these subgroups (overall HR=2.32 [1.82,2.94]; p Disclosure L.A.
