TWILIGHT CKD-DM: Ticagrelor Monotherapy Preferable in Concomitant CKD and Diabetes

Results of a post hoc analysis of the TWILIGHT trial provide insight into the effects of ticagrelor monotherapy compared to dual therapy with aspirin in patients with concomitant CKD and diabetes.

Ticagrelor monotherapy reduced risk of clinically relevant and major bleeding with no significant increase in ischemic events compared to ticagrelor plus aspirin in patients with concomitant diabetes and chronic kidney disease, according to a new analysis of the TWILIGHT trial.

Presented at the European Society of Cardiology (ESC) Congress 2021, the study demonstrates the effects of ticagrelor monotherapy compared against ticagrelor plus aspirin seen in the original TWILIGHT study were consistent in this patient subgroup.

With rates of diabetes and chronic kidney disease increasing in recent years, developing an understanding of best practices in anticoagulation among this patient population has the potential to reduce event rates and improve patient outcomes for a large patient population. With this in mind, TWILIGHT CKD-DM was designed to assess whether a short dual antiplatelet therapy course reduced BARC 2, 3, or 5 bleeding without increasing death, myocardial infarction, or stroke among patients in the trial with concomitant diabetes and chronic kidney disease.

Of the 7119 patients randomized in the TWILIGHT trial, 499 (8.0%) had concomitant diabetes and chronic kidney disease. For the purpose of analysis, patients were stratified according to diabetes status and presence of chronic kidney disease. These groups included 561 patients with chronic kidney disease but without diabetes, 1822 patients with diabetes but without chronic kidney disease, and 3391 patients without either diagnosis.

Upon analysis, results suggested ticagrelor monotherapy was associated with significant. Reductions in BARC 2, 3, or 5 and BARC 3 or 5 bleeding events, irrespective of diabetes and chronic kidney disease status. Investigators pointed out the results of this post hoc analysis are intended to be hypothesis-generating and larger studies are needed to confirm these findings.
