Results of new exploratory analyses assessing the incidence of hypoglycemia with linagliptin in adults with type 2 diabetes announced

Lower incidence of hypoglycemia observed when linagliptin is added to basal insulin in elderly patients and with linagliptin treatment vs. glimepiride, according to two presentations at the American Diabetes Association 73rd Scientific Sessions®

RIDGEFIELD, Conn. and INDIANAPOLIS, June 22, 2013 /PRNewswire/ -- Boehringer Ingelheim Pharmaceuticals, Inc. and Eli Lilly and Company (NYSE: LLY) today announced results from two exploratory analyses assessing the risk of hypoglycemia with linagliptin treatment in adults with type 2 diabetes (T2D).1, 2

In an exploratory analysis of data from two phase III trials, elderly people with T2D (mean age 74 years) treated with linagliptin as add-on to stable basal insulin regimen trended towards a 37 percent and 34 percent lower occurrence of overall hypoglycemia (odds ratio [OR] 0.63 [95 percent confidence interval [CI]: 0.37- 1.10]) and confirmed hypoglycemia (0.66 [0.36-1.21]), respectively, compared with people treated with placebo as add-on to basal insulin.1 Overall hypoglycemia included all investigator-defined hypoglycemic events, while confirmed hypoglycemia was defined as blood glucose levels at or below 70 mg/dL.

In a separate exploratory analysis of two-year data from a phase III trial comparing linagliptin to glimepiride, fewer people treated with the DPP-4 inhibitor linagliptin versus the sulfonylurea glimepiride experienced hypoglycemia (7.5 percent vs. 36.1 percent; p<0.0001).2 After excluding events during dose escalation of glimepiride (1-4 mg in weeks 0-16), a difference in those reporting hypoglycemia still remained present (5.9 percent vs. 25.8 percent; p<0.0001). The difference in the incidence of hypoglycemia between linagliptin and glimepiride was observed at all time points tested, all dose levels, and regardless of change from baseline in HbA1c.2 Hypoglycemia in this analysis was defined as any investigator-reported hypoglycemic event.

At weeks 4, 8, 12, 16 and 104, the percentage of people who experienced a hypoglycemic event was higher with glimepiride versus linagliptin in each quartile of HbA1c change from baseline (all p<0.0001). The percentage of people who experienced hypoglycemia was not increased with greater reductions in HbA1c in either group. In all four-week intervals, the percentage of people who experienced a hypoglycemic event was lower with linagliptin versus glimepiride.1

About the Studies
Findings from the first exploratory analysis of data on elderly people with T2D (n=247; mean age, 74 years; baseline HbA1c, 8.2 percent) who had linagliptin or placebo added onto basal insulin therapy (baseline dose 36 U/day) from two phase III studies of 24 and > 52 weeks. The analysis measured the relative ORs for overall and confirmed hypoglycemia (the latter defined as blood glucose < 70 mg/dL). The insulin doses did not change notably throughout the trials.1

The findings from the second analysis are based on two-year data from a randomized, double-blind study of linagliptin 5 mg qd (n=777) versus glimepiride 1 mg to 4 mg qd (n=775) in people with T2D previously uncontrolled with metformin therapy.2 The study showed comparable reductions in HbA1c between the two treatments.2 For the exploratory analysis, the risk of investigator-reported hypoglycemia for linagliptin was compared with glimepiride based on dose, over time, and by HbA1c reduction. People randomized to glimepiride started treatment on 1 mg. Those who did not achieve a fasting plasma glucose level of 110 mg/dL at 4 weeks and who were not at hypoglycemia risk were subsequently uptitrated stepwise up to a maximum of 4 mg qd.2

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 type 2 diabetes. 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). If patients have had pancreatitis in the past, it is not known if they have a higher chance of getting pancreatitis while taking linagliptin. Linagliptin is a DPP-4 inhibitor that does not require dose adjustment, regardless of declining renal function or hepatic impairment.

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 FDA. Visit or call 1-800-FDA-1088.
