FDA Approves Tradjenta (linagliptin) Tablets for the Treatment of Type 2 Diabetes

RIDGEFIELD, Conn. and INDIANAPOLIS, May 2, 2011 /PRNewswire/ — Boehringer
Ingelheim Pharmaceuticals, Inc. and Eli Lilly and Company (NYSE: LLY) today
announced that the U.S. Food and Drug Administration (FDA) has approved
Tradjenta(TM) (linagliptin) tablets, a prescription medication used along with
diet and exercise to lower blood sugar in adults with type 2 diabetes. TRADJENTA
can be used as monotherapy or in combination with other commonly prescribed
medications for type 2 diabetes — metformin, sulfonylurea or pioglitazone –
and demonstrated reductions in hemoglobin A1C (HbA1C or A1C) levels up to 0.7
percent (compared to placebo). A1C is measured in people with diabetes to
provide an index of blood sugar control for the previous two to three months.
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). It
has not been studied in combination with insulin.

TRADJENTA belongs to a class of prescription medications called dipeptidyl
peptidase-4 (DPP-4) inhibitors and is the first member of its class to be
approved at one dosage strength (5 mg, once daily). With TRADJENTA, no dose
adjustment is recommended for patients with kidney or liver impairment.
TRADJENTA is a tablet that can be taken with or without food. TRADJENTA lowers
blood sugar in a glucose-dependent manner by increasing incretin levels, which
increase insulin levels after meals and throughout the day.

“Many people with type 2 diabetes are not able to control their blood sugar with
diet and exercise alone and may also require one or more medications,” said John
Gerich M.D., professor of medicine, University of Rochester School of Medicine.
“The FDA approval of TRADJENTA is exciting because there is only one dose to
remember for all patients, regardless of kidney or liver impairment. With
TRADJENTA, physicians will have another option for managing type 2 diabetes, a
potentially devastating condition.”

TRADJENTA 5 mg once daily was approved based on a clinical trial program which
included approximately 4,000 adults with type 2 diabetes. Included in the
program were placebo-controlled studies evaluating TRADJENTA as monotherapy and
in combination with the commonly prescribed medications for type 2 diabetes -
metformin, sulfonylurea or pioglitazone. TRADJENTA showed statistically
significant A1C reductions of up to 0.7 percent when used as monotherapy
(compared to placebo). When used in combination with metformin, sulfonylurea,
and metformin plus sulfonylurea, the addition of TRADJENTA resulted in
significant A1C reductions of 0.6, 0.5, and 0.6 percent respectively (compared
to placebo). In the initial combination of TRADJENTA plus pioglitazone,
significant reductions in A1C of 0.5 percent were observed compared to placebo.

Treatment with TRADJENTA also produced significant reductions in fasting plasma
glucose (FPG) compared to placebo, when used as monotherapy and in combination
with metformin, sulfonylurea or pioglitazone. Treatment with TRADJENTA produced
significant reductions in two-hour post-prandial glucose (PPG) levels compared
with placebo as monotherapy and when used in combination with metformin. FPG is
used to determine glucose levels in a fasting state (usually upon wakening in
the morning), and PPG is used to determine glucose levels after meals (usually
two hours after eating).

In controlled studies, change from baseline in body weight did not differ
significantly between groups when TRADJENTA was administered as monotherapy, in
combination with metformin or in combination with metformin plus sulfonylurea.
Patients treated with TRADJENTA exhibited a significant mean decrease from
baseline body weight compared to a significant weight gain in patients
administered sulfonylurea (-1.1 kg vs. +1.4 kg. p<0.0001). Patient weight
increased in both the TRADJENTA plus pioglitazone and placebo plus pioglitazone
groups during the study with an adjusted mean change from baseline of 2.3 kg and
1.2 kg, respectively (p=0.0141).

Adverse reactions reported in greater than or equal to five percent of patients
treated with TRADJENTA and more commonly than in patients treated with placebo
included nasopharyngitis. Hypoglycemia was more commonly reported in patients
treated with the combination of TRADJENTA and sulfonylurea compared with those
treated with the combination of placebo and sulfonylurea. The incidence of
hypoglycemia was similar to placebo when TRADJENTA was administered as
monotherapy or in combination with metformin or pioglitazone. Pancreatitis was
reported more often in patients randomized to TRADJENTA (one per 538
person-years versus zero in 433 person-years for comparator).

“Type 2 diabetes is increasing at an alarming rate and we are proud to offer a
new treatment option that could potentially help the millions of people with
type 2 diabetes whose blood sugar is uncontrolled,” said Albert Ros, president
and CEO, Boehringer Ingelheim Pharmaceuticals, Inc. “When we introduce a new
medicine to the marketplace, our goal is to improve patient care and we are
hopeful that TRADJENTA will help do that.”

The FDA approval of TRADJENTA marks the first regulatory milestone since the
formation of the Boehringer Ingelheim and Eli Lilly and Companyworldwide
diabetes alliance in January 2011. The alliance leverages the collective
scientific expertise and business capabilities of two leading research-driven
pharmaceutical companies to address patient needs arising from the growing
global diabetes epidemic.

“Our alliance with Boehringer Ingelheim represents one of the most robust
diabetes pipelines in the pharmaceutical industry,” said Enrique Conterno,
president of Lilly Diabetes. “TRADJENTA is the first regulatory approval of what
we hope will be many new treatment options this alliance brings to the millions
of Americans living with type 2 diabetes.”

The overall clinical development program for TRADJENTA consists of 30 studies
completed, underway or planned. TRADJENTA is currently under regulatory review
in the EU and Japan.

About Diabetes

Approximately 25.8 million Americans(1) and an estimated 220 million people
worldwide(2) have type 1 and type 2 diabetes. Type 2 diabetes is the most common
type, accounting for an estimated 95 percent of all diabetes cases.(1) Diabetes
is a chronic disease that occurs when the body either does not properly produce,
or use, the hormone insulin.(3)

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).

It is not known if TRADJENTA is safe and effective when used with insulin.

Important Safety Information

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 are rash, raised red
patches on your skin (hives), swelling of your face, lips, 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 taking TRADJENTA?

Tell your doctor about all the medicines you take, including prescription and
non-prescription medicines, vitamins, and herbal supplements.

Tell your doctor if you take other medicines that can lower your blood sugar,
such as a sulfonylurea or insulin. If you take TRADJENTA with another medicine
that can cause low blood sugar (hypoglycemia), such as a sulfonylurea or
insulin, your risk of getting low blood sugar is higher. The dose of your
sulfonylurea medicine 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 heart
beat, sweating, or feeling jittery.

Also tell your doctor if you take rifampin (Rifadin®, Rimactane®, Rifater®,
Rifamate®), an antibiotic that is used to treat tuberculosis.

TRADJENTA may affect the way other medicines work, and other medicines may
affect how TRADJENTA works.

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 and sore
throat.

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