ENILWORTH, NJ, USA I April 27, 2015 I Merck (NYSE:MRK), known as MSD outside the United States and Canada, today announced that the Trial Evaluating Cardiovascular Outcomes with Sitagliptin (TECOS) of Merck’s DPP-4 inhibitor, JANUVIA® (sitagliptin), achieved its primary endpoint of non-inferiority for the composite cardiovascular (CV) endpoint. Among secondary endpoints, there was no increase in hospitalization for heart failure in the sitagliptin group versus placebo. The complete results of TECOS will be presented on June 8, 2015 at the 75th Scientific Sessions of the American Diabetes Association.

The TECOS CV safety trial was led by an independent academic research collaboration between the University of Oxford Diabetes Trials Unit (DTU) and the Duke University Clinical Research Institute (DCRI).

Indications and Limitations of Use for JANUVIA® (sitagliptin)

JANUVIA is indicated, as an adjunct to diet and exercise, to improve glycemic control in adults with type 2 diabetes mellitus. JANUVIA should not be used in patients with type 1 diabetes or for the treatment of diabetic ketoacidosis. JANUVIA has not been studied in patients with a history of pancreatitis. It is unknown whether patients with a history of pancreatitis are at increased risk of developing pancreatitis while taking JANUVIA.

Selected Important Risk Information

JANUVIA is contraindicated in patients with a history of a serious hypersensitivity reaction to sitagliptin, such as anaphylaxis or angioedema. There have been postmarketing reports of acute pancreatitis, including fatal and nonfatal hemorrhagic or necrotizing pancreatitis, in patients taking JANUVIA. After initiating JANUVIA, observe patients carefully for signs and symptoms of pancreatitis. If pancreatitis is suspected, promptly discontinue JANUVIA and initiate appropriate management.

About the TECOS CV Safety Trial

TECOS was an event-driven trial conducted in adults with type 2 diabetes and a history of cardiovascular disease. The study was designed to assess the CV safety of long-term treatment with JANUVIA as part of usual diabetes care compared with usual care without JANUVIA. The primary endpoint was the composite of time to the first of any of the following confirmed events: cardiovascular-related death, nonfatal myocardial infarction, nonfatal stroke, or unstable angina requiring hospitalization.

TECOS enrolled 14,724 participants from 38 countries between December 2008 and July 2012. The median patient follow-up was approximately three years.

Selected important risk information about JANUVIA® (sitagliptin) 25 mg, 50 mg and 100 mg tablets (continued)

Assessment of renal function is recommended prior to initiating JANUVIA and periodically thereafter. A dosage adjustment is recommended in patients with moderate or severe renal insufficiency and in patients with end-stage renal disease requiring hemodialysis or peritoneal dialysis. Caution should be used to ensure that the correct dose of JANUVIA is prescribed.

There have been postmarketing reports of worsening renal function, including acute renal failure, sometimes requiring dialysis. A subset of these reports involved patients with renal insufficiency, some of whom were prescribed inappropriate doses of sitagliptin.

When JANUVIAwas used in combination with a sulfonylurea or insulin, medications known to cause hypoglycemia, the incidence of hypoglycemia was increased over that of placebo. Therefore, a lower dose of sulfonylurea or insulin may be required to reduce the risk of hypoglycemia.

The incidence (and rate) of hypoglycemia based on all reports of symptomatic hypoglycemia were: 12.2 percent (0.59 episodes per patient-year) for JANUVIA 100 mg in combination with glimepiride (with or without metformin), 1.8 percent (0.24 episodes per patient-year) for placebo in combination with glimepiride (with or without metformin), 15.5 percent (1.06 episodes per patient-year) for JANUVIA (sitagliptin) 100 mg in combination with insulin (with or without metformin), and 7.8 percent (0.51 episodes per patient-year) for placebo in combination with insulin (with or without metformin).

There have been postmarketing reports of serious hypersensitivity reactions in patients treated with JANUVIA® (sitagliptin), such as anaphylaxis, angioedema and exfoliative skin conditions including Stevens-Johnson syndrome. Onset of these reactions occurred within the first 3 months after initiation of treatment with JANUVIA, with some reports occurring after the first dose. If a hypersensitivity reaction is suspected, discontinue JANUVIA, assess for other potential causes for the event, and institute alternative treatment for diabetes.

Angioedema has also been reported with other dipeptidyl peptidase-4 (DPP-4) inhibitors. Use caution in a patient with a history of angioedema with another DPP-4 inhibitor because it is unknown whether such patients will be predisposed to angioedema with JANUVIA.

There have been no clinical studies establishing conclusive evidence of macrovascular risk reduction with JANUVIA or with any other antidiabetic drug.

In clinical studies, the adverse reactions reported, regardless of investigator assessment of causality, in greater than or equal to 5 percent of patients treated with JANUVIA as monotherapy and in combination therapy, and more commonly than in patients treated with placebo, were upper respiratory tract infection, nasopharyngitis and headache.
