New analysis presented at ADA shows improvement in albuminuria with linagliptin in patients at high risk of declining renal function

Data presented at the American Diabetes Association® (ADA) 72nd Scientific Sessions provided insights for use of linagliptin in adults with type 2 diabetes (T2D) and at high risk of declining renal function

Boehringer Ingelheim and Eli Lilly and Company (NYSE:LLY) today announced results from a post-hoc analysis that showed linagliptin is associated with improvements in glucose levels and a significant reduction in urinary albumin-to-creatinine ratio (UACR) of 33% (p<0.05) from baseline in patients with T2D and at high risk of declining renal function (some degree of albuminuria at baseline). UACR is a measure of albuminuria in T2D patients with declining renal function.1 Linagliptin is a once-daily tablet that is used along with diet and exercise either as monotherapy or in combination with other treatments, such as metformin or metformin + sulphonylurea, to improve glycaemic control in adults with T2D.2,3

The post-hoc analysis included 227 T2D patients at high risk of declining renal function from four randomised, 24-week trials who were on stable treatment with one of two types of blood pressure medicines that are the standard treatment for diabetic renal disease – angiotensin-converting enzyme inhibitors (ACEs) or angiotensin receptor blockers (ARBs).1 In addition to a reduction in glucose levels, as measured by a 0.71% change in haemoglobin A1c [HbA1c] versus placebo at 24 weeks, a 29% reduction in UACR was demonstrated with linagliptin versus placebo.1 HbA1c is measured in patients with diabetes to provide an index of blood glucose control for the previous two to three months.

“This analysis is important because approximately 65% of patients living with type 2 diabetes are at risk of declining renal function, which can limit treatment options,” said Professor Per Henrik Groop, Division of Nephrology, Helsinki University Central Hospital, Finland. “In this analysis, patients treated with linagliptin showed improvements in blood glucose levels and reduction of albumin in the urine, a sign for renal dysfunction. We will continue to further investigate this area as we recognise the importance of considering declining renal function when treating type 2 diabetes patients.”

The primary endpoint in each of these four trials was the reduction in HbA1c levels from baseline at 24 weeks.

Linagliptin (5 mg, once daily) is marketed in the U.S. as Tradjenta™ (linagliptin), in Europe as Trajenta™ (linagliptin), and in other global markets as a once-daily tablet that is used along with diet and exercise either as monotherapy or in combination with other treatments, such as metformin or metformin + sulphonylurea, to improve glyceamic control in adults with T2D. Linagliptin should not be used in patients with type 1 diabetes or for the treatment of diabetic ketoacidosis (increased ketones in the blood or urine). Linagliptin is not approved in combination with insulin. With linagliptin, no dose adjustment is required regardless of declining renal function or hepatic impairment.2,3

About the Albuminuria Post-hoc Analysis

In a post-hoc analysis, data from four randomised, double-blind, 24-week, placebo-controlled trials of linagliptin monotherapy, linagliptin with add-on to metformin, linagliptin with add-on to metformin and sulphonylurea and a factorial study of linagliptin in initial combination with metformin were pooled (n=2472) to explore the clinical effect of linagliptin on albuminuria in patients with T2D who are at high risk of declining renal function (including albuminuria at baseline). The primary objective of these four trials was to analyse the change in HbA1c from baseline at 24 weeks.1

UACR was collected in the four trials as safety data. The endpoint was the percentage change in geometric mean UACR. In this analysis, 492 (19.9%) patients met UACR (30≤UACR ≤3000 mg/g creatinine) and estimated glomerular filtration rate (eGFR) thresholds (eGFR >30 ml/ min/1.73m2) of whom 46% received stable ACE/ARB therapy (linagliptin n=168; placebo n=59). Mean baseline HbA1c and median UACR were 8.2% versus 8.5% and 76 versus 78 mg/g creatinine for the linagliptin and placebo groups, respectively. After 24 weeks, placebo-corrected changes in HbA1c and FPG were -0.71% and -26 mg/dL respectively (both p<0.0001). Linagliptin significantly lowered UACR by 33% compared to baseline (p<0.05) with a between-group difference of -29% (p<0.05).1

About Diabetes

An estimated 366 million people worldwide have type 1 and type 2 diabetes.4 Type 2 diabetes is the most common type, accounting for an estimated 90 to 95% of all diabetes cases.5 Diabetes is a chronic disease that occurs when the body either does not properly produce, or use, the hormone insulin.6
