Linagliptin Demonstrated Significant HbA1c Reduction in Elderly People With Type 2 Diabetes With Inadequate Glycemic Control

Phase III safety and efficacy data of TRADJENTA® (linagliptin) tablets in elderly people with type 2 diabetes published in The Lancet

PR Newswire

RIDGEFIELD, Conn. and INDIANAPOLIS, Aug. 15, 2013 /PRNewswire/ -- Data published in The Lancet showed that elderly people with type 2 diabetes (T2D) treated for 24 weeks with the dipeptidyl peptidase-4 (DPP-4) inhibitor linagliptin (TRADJENTA®), marketed by Boehringer Ingelheim Pharmaceuticals, Inc. and Eli Lilly and Company (Lilly; NYSE: LLY), experienced significant reductions in blood glucose levels (HbA1c) compared with those receiving placebo. In addition, the overall safety and tolerability profile of linagliptin was similar to placebo.1

Linagliptin, which is marketed as TRADJENTA® (linagliptin) tablets in the U.S., is a once-daily 5-mg tablet used along with diet and exercise to improve glycemic control in adults with T2D. TRADJENTA should not be used in patients with type 1 diabetes or for the treatment of diabetic ketoacidosis (increased ketones in the blood or urine). TRADJENTA has not been studied in patients with a history of pancreatitis and it is unknown whether patients with a history of pancreatitis are at an increased risk for the development of pancreatitis while using TRADJENTA.

"Elderly individuals represent approximately 15 percent of people with type 2 diabetes worldwide,2" said Professor Anthony H. Barnett, MD, FRCP, Heart of England NHS Foundation Trust and University of Birmingham, United Kingdom. "This study may help inform treatment decisions for improving glycemic control in the elderly."

The publication reports on a 24-week, double-blind, parallel-group, multinational, phase III study in 241 elderly people (=70 years; mean age, 74.9 years) with T2D randomized to receive linagliptin 5 mg (n=162) or placebo (n=79), in addition to existing glucose-lowering drugs (i.e. metformin and/or sulfonylurea and/or basal insulin). The primary endpoint was change in HbA1c from baseline (7.8 percent for linagliptin versus 7.7 percent for placebo) to week 24. Key results from the study showed that the mean change from baseline in HbA1c  with linagliptin was -0.64 percent (p<0.0001) after 24 weeks, which showed superiority versus placebo, adjusted for a mean 0.04 percent HbA1C increase for placebo . In addition, analysis of a secondary endpoint showed that the placebo-adjusted mean reduction in fasting plasma glucose from baseline with linagliptin was -20.7 mg/dL (-1.15 mmol/L; p<0.0001). 

The percentage of people with any adverse event was the same in both treatment groups (75.9 percent). Common adverse events included hypoglycemia (low blood glucose; 22.8 percent and 16.5 percent for linagliptin and placebo, respectively), nasopharyngitis (common cold; 10.5 percent in the linagliptin arm and 8.9 percent on placebo), diarrhea (5.6 percent in the linagliptin arm and 2.5 percent on placebo), hyperglycemia (high blood glucose; 5.6 percent and 10.1 percent for linagliptin and placebo, respectively), back pain (7 percent for linagliptin), fall (4.3 percent and 2.5 percent for linagliptin and placebo, respectively) and urinary tract infection (4.3 percent in the linagliptin arm and 6.3 percent on placebo). One patient per group had a drug-related adverse event leading to discontinuation of the study.  Investigator-defined hypoglycemia occurred in 24.1 percent of the linagliptin group and 16.5 percent of the placebo group.

"Elderly people with type 2 diabetes have different challenges managing their blood sugar levels," said Christophe Arbet-Engels, MD, PhD, vice president, metabolic clinical development and medical affairs, Boehringer Ingelheim Pharmaceuticals, Inc. "This study shows linagliptin may help to reduce blood sugar levels in elderly people with inadequately controlled diabetes, and adds to the growing body of evidence for the safety and efficacy profile for linagliptin in this population."

About the study

The study was conducted at 33 centers in five countries (Australia, Canada, Denmark, The Netherlands and Sweden). A total of 241 people who were (>/=70 years with T2D, had HbA1c of (>/=7.0 percent and received metformin and/or sulfonylurea and/or basal insulin were randomized 2:1 to once-daily oral treatment with linagliptin 5 mg or placebo for 24 weeks.

What are TRADJENTA tablets?

TRADJENTA is a prescription medicine that is used along with diet and exercise to lower blood sugar in adults with type 2 diabetes.

TRADJENTA is not for people with type 1 diabetes or for people with diabetic ketoacidosis (increased ketones in the blood or urine).

If you have had inflammation of the pancreas (pancreatitis) in the past, it is not known if you have a higher chance of getting pancreatitis while you take TRADJENTA.

Important Safety Information

What is the most important information I should know about TRADJENTA?
Serious side effects can happen to people taking TRADJENTA, including inflammation of the pancreas (pancreatitis), which may be severe and lead to death. Before you start taking TRADJENTA, tell your doctor if you have ever had pancreatitis, gallstones, a history of alcoholism, or high triglyceride levels.

Stop taking TRADJENTA and call your doctor right away if you have pain in your stomach area (abdomen) that is severe and will not go away. The pain may be felt going from your abdomen through to your back. The pain may happen with or without vomiting. These may be symptoms of pancreatitis.

Who should not take TRADJENTA?
Do not take TRADJENTA if you are allergic to linagliptin or any of the ingredients in TRADJENTA.

Symptoms of a serious allergic reaction to TRADJENTA may include rash, itching, flaking or peeling; raised red patches on your skin (hives); swelling of your face, lips, tongue and throat that may cause difficulty breathing or swallowing. If you have any symptoms of a serious allergic reaction, stop taking TRADJENTA and call your doctor right away.

What should I tell my doctor before using TRADJENTA?
Tell your doctor about all the medicines you take, including prescription and non-prescription medicines, vitamins, and herbal supplements. TRADJENTA may affect the way other medicines work, and other medicines may affect how TRADJENTA works.

Especially tell your doctor if you take

  • Other medicines that can lower your blood sugar, such as a sulfonylurea or insulin.
    • TRADJENTA may cause serious side effects, including low blood sugar (hypoglycemia). If you take TRADJENTA with another medicine that can cause low blood sugar, such as sulfonylurea or insulin, your risk of getting low blood sugar is higher. The dose of your sulfonylurea or insulin may need to be lowered while you take TRADJENTA.
    • Signs and symptoms of low blood sugar may include headache, drowsiness, weakness, dizziness, confusion, irritability, hunger, fast heartbeat, sweating, or feeling jittery.
  • rifampin (Rifadin®, Rimactane®, Rifater®, Rifamate®)*, an antibiotic that is used to treat tuberculosis.

Tell your doctor if you are pregnant or planning to become pregnant or are breastfeeding or plan to breastfeed.

What are the possible side effects of TRADJENTA?
The most common side effects of TRADJENTA include stuffy or runny nose, sore throat, cough and diarrhea.

You are encouraged to report negative side effects of prescription drugs to the U.S. FDA. Visit www.fda.gov/medwatch or call 1-800-FDA-1088.
