  • Linagliptin did not increase the risk of adverse cardiovascular events, hospitalization for heart failure or adverse kidney events compared with placebo in older people with type 2 diabetes in a prespecified subgroup analysis of the CARMELINA® cardiovascular outcome trial1
  • In addition, linagliptin did not increase the risk of hypoglycemia compared with placebo in this population1

INGELHEIM, Germany–(BUSINESS WIRE)–Boehringer Ingelheim have announced the results of a subgroup analysis of the CARMELINA® trial which demonstrate that linagliptin did not increase the risk of adverse cardiovascular events or hypoglycemia compared with placebo in older people with type 2 diabetes.1 The findings have been published in the Diabetes Obesity and Metabolism journal.

Population aging has shifted the epidemiology of diabetes towards older age.1 Currently, approximately 136 million of the estimated 463 million people with diabetes are aged over 65 years.2 However, despite the high prevalence, older patients have historically been underrepresented in clinical trials of glucose-lowering drugs.3

The recent CARMELINA® cardiovascular outcome trial enrolled people aged 18 years and older with no maximum age restriction.4 The prespecified CARMELINA® subgroup analysis evaluated clinical outcomes and adverse events with the main findings grouped into the following predefined age categories: <65, 65 to <75, and ≥75 years.1

“This subset analysis shines a spotlight on the older population living with type 2 diabetes. These individuals can be frail, have a high rate of comorbidities and can be on multidrug regimens, all of which present a challenge for their glucose management,” said Waheed Jamal, MD, Corporate Vice President and Head of CardioMetabolic Medicine, Boehringer Ingelheim. “As the older population also has the highest incidence of type 2 diabetes of any age group, this analysis will be invaluable in helping clinicians manage the treatment of this patient group, previously underrepresented in clinical studies.”

Linagliptin did not increase the risk of adverse kidney outcomes, cardiovascular events or hospitalization for heart failure compared with placebo across age groups.1 The incidence of adverse events, including hypoglycemia, increased with age but was similar with linagliptin and placebo despite HbA1c reduction with linagliptin.1 Linagliptin improved glycemic control compared with placebo in all age groups.1

“Their advanced age, combined with established cardiovascular and/or kidney disease, means the older population of CARMELINA® was comprised of high-risk individuals with type 2 diabetes,” continued Dr. Jamal. “The results should reassure healthcare professionals that linagliptin is suitable for a wide patient population to improve glycemic control whilst ensuring cardiovascular and renal safety.”

About CARMELINA®

CARMELINA® is a multi-national, randomized, double-blind, placebo-controlled clinical trial that involved 6,979 adults with type 2 diabetes from 27 countries at more than 600 sites observed for a median duration of 2.2 years.4,5 The study was designed to assess the effect of linagliptin (5mg once daily) compared to placebo (both added to standard of care) on cardiovascular outcomes in adults with type 2 diabetes and high cardiovascular risk, the majority of whom also had kidney disease.4,5 This population of people with high risk of cardiovascular and/or kidney disease reflects patients that doctors see in their daily practice.6 Standard of care included both glucose lowering agents and cardiovascular drugs (including antihypertensive and lipid lowering agents).

CARMELINA® was led by an academic trial steering committee and the Boehringer Ingelheim and Eli Lilly and Company Diabetes Alliance. Compared to other recently reported outcome trials of dipeptidyl peptidase-4 (DPP-4) inhibitors in type 2 diabetes, CARMELINA® included the highest proportion of patients with impaired kidney function.7*

About Trajenta® (linagliptin)

Trajenta® is a one dose, once daily DPP-4 inhibitor that provides significant efficacy in the reduction of blood sugar levels for adults with type 2 diabetes. It can be prescribed for adults with type 2 diabetes regardless of age, disease duration, ethnicity, body mass index (BMI), liver and kidney function.8 Trajenta® has the lowest kidney excretion rate of all globally available DPP-4 inhibitors.9–12

Linagliptin is developed and commercialized by the Boehringer Ingelheim and Eli Lilly and Company Alliance.

About our cardiovascular outcome trials

Cardiovascular outcome trials are highly clinically relevant, as cardiovascular disease is a major complication and the leading cause of death in type 2 diabetes. Worldwide, most people with type 2 diabetes die of a cardiovascular event.13 In 2015, Boehringer Ingelheim and Eli Lilly and Company announced results from the landmark cardiovascular outcome trial EMPA-REG OUTCOME® with the SGLT2 inhibitor, empagliflozin, which reduced the relative risk of cardiovascular death by 38 percent in adults with type 2 diabetes and established cardiovascular disease, on top of standard of care.†‡14–16 As a result, empagliflozin was the first oral type 2 diabetes medicine to have either a cardiovascular indication or data on the reduction of the risk of cardiovascular death included in the label in many countries.14,15

CAROLINA® is one of two cardiovascular outcome trials with the DPP-4 inhibitor, linagliptin.17,18 CAROLINA® and the CArdiovascular safety and Renal Microvascular outcomE with LINAgliptin in patients with type 2 diabetes at high vascular risk trial (CARMELINA®)4,5 provide one of the most comprehensive datasets on the long-term safety of a DPP-4 inhibitor.

CARMELINA® is a multi-national, randomized, double-blind, placebo-controlled clinical trial that involved 6,979 adults with type 2 diabetes from 27 countries at more than 600 sites observed for a median duration of 2.2 years.4,5 CARMELINA® studied the impact of Trajenta® (linagliptin) on cardiovascular and kidney safety in adults with type 2 diabetes at high risk for heart and/or kidney disease.4,5 The trial met its primary endpoint,§ with linagliptin demonstrating a similar cardiovascular safety profile compared to placebo when added to standard of care.5 CARMELINA® also included a key secondary composite endpoint,** showing a similar kidney safety profile compared to placebo.The overall safety profile of linagliptin in CARMELINA® was consistent with previous data and no new safety signals were observed.5,6 CARMELINA® also showed a similar rate of hospitalization for heart failure for linagliptin compared to placebo.5
