1-OR: Analyses of First Plus Recurrent Cardiovascular (CV) and Hospitalization Events in the CAROLINA Trial

Abstract

CAROLINA® (CARdiovascular Outcome Study of LINAgliptin Versus Glimepiride in Type 2 Diabetes) was a randomized controlled clinical trial designed to compare the effects of linagliptin (LINA) with glimepiride (GLIM) on CV events and other outcomes in patients with relatively early type 2 diabetes (T2D) with elevated CV risk. To characterize the effects on net CV disease and hospitalization burden of this population, we assessed effects of LINA vs. GLIM on all first plus recurrent CV events and any-cause hospitalizations using a negative binomial model. A total of 6033 participants were enrolled (mean age 64.0 years, HbA1c 7.2%, BMI 30.1 kg/m2, eGFR 77 ml/min/1.73m2, median T2D duration 6.3 years, UACR 9 mg/g, 42% with CV disease, 4.5% with heart failure [HF]). Adding recurrent events increased the number of events for analysis from first event by 10 to 77% across CV/HF outcomes and by 119% for hospitalizations with corresponding increase in rates per 100-patient years in both treatment groups (e.g., 3P-MACE from 2.1 to 2.8 [LINA] and 2.1 to 2.9 [GLIM]), over median 6.3 years. Analyses of first-event and first plus recurrent events are presented (Fig). In conclusion, no significant differences were observed between LINA or GLIM for either first or recurrent CV or hospitalization events. These data underscore the significant CV disease burden experienced even in relatively early T2D and reinforce the safety of LINA. Disclosure N.
