Post-hoc analysis of linagliptin phase 3 data in adults with type 2 diabetes and albuminuria presented
RIDGEFIELD, Conn. and INDIANAPOLIS, June 9, 2012 /PRNewswire/ — Boehringer Ingelheim Pharmaceuticals, Inc. and Eli Lilly and Company (NYSE: LLY) today announced results from a post-hoc analysis, which explored the clinical effect of linagliptin on albuminuria in patients with type 2 diabetes who had early diabetic nephropathy (renal disease). The primary endpoint of the analysis was changes to the urinary albumin-to-creatinine ratio (UACR), which is a measure of renal function in patients with type 2 diabetes and diabetic nephropathy.
This post-hoc analysis, which is being presented at the American Diabetes Association’s (ADA’s) 72nd Scientific Sessions®, included 227 patients with type 2 diabetes and diabetic nephropathy from four randomized, 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) and angiotensin receptor blockers (ARBs). The post-hoc analysis showed a 29 percent reduction in UACR with linagliptin plus ACE/ARBs, versus ACE/ARBs alone at 24 weeks (p=0.0305). Since this was a post-hoc analysis, it did not control for other contributing factors. In addition, the linagliptin treatment group reduced glucose levels (as measured by a 0.71 percent change in hemoglobin A1c [HbA1c or A1C] versus the placebo treatment group at 24 weeks; p<0.0001). A1C is measured in people with diabetes to provide an index of blood glucose control for the previous two to three months.
“As these results are based on a post-hoc analysis, this interesting observation warrants further investigation,” said John Smith, M.D., Ph.D., senior vice president for clinical development and medical affairs, Boehringer Ingelheim Pharmaceuticals, Inc.
About the Post-hoc Analysis
Data from four randomized, double-blind, 24-week, placebo-controlled trials of linagliptin monotherapy, linagliptin with add-on to metformin, linagliptin with add-on to metformin and sulfonylurea and a factorial study of linagliptin in initial combination with metformin were pooled for the analysis (n=2472) to explore the clinical effect of linagliptin on albuminuria in patients with type 2 diabetes who had early diabetic nephropathy. The primary objectives of these four trials were to evaluate the reduction in A1C from baseline at 24 weeks.
UACR was collected in the four trials as safety data. The endpoint of this post-hoc analysis was the percentage change in the average (mean) UACR. In this analysis, 492 (19.9 percent) patients met UACR (30 to 3,000 mg/g creatinine) and estimated glomerular filtration rate (eGFR; >30 mL/min/1.73 m(2)) thresholds, of whom 46 percent received stable ACE/ARB therapy (linagliptin n=168; placebo n=59). Mean baseline A1C was 8.2 percent versus 8.5 percent and median baseline UACR was 76 versus 78 mg/g creatinine for the linagliptin and placebo groups, respectively.
The incidence of hypoglycemia was higher in the linagliptin treatment group (14.3%) compared with the placebo treatment group (0%).
Linagliptin is marketed as Tradjenta® 5mg tablets in the U.S.
