GSK receives US approval for once-weekly type 2 diabetes treatment, Tanzeum™ (albiglutide)

Issued: London UK – LSE Announcement

GlaxoSmithKline plc (LSE/NYSE: GSK) today announced that the US Food and Drug Administration (FDA) has approved Tanzeum^TM (albiglutide) for injection, for subcutaneous use, as a once-weekly treatment for type 2 diabetes. Tanzeum has been approved as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus.

Albiglutide, a glucagon-like peptide-1 receptor agonist (GLP-1), is a biological product for the treatment of type 2 diabetes, administered once-weekly using an injector pen supplied with a 5mm 29-gauge thin-walled needle. Glucagon-like peptide-1 is an important incretin hormone that helps reduce blood glucose levels but, in people with type 2 diabetes, its production is often reduced or absent.

Vlad Hogenhuis, Senior Vice-President and Head, GSK Global Cardiovascular, Metabolic and Neurosciences Franchise, said: “Many type 2 diabetes patients struggle to keep their blood sugar within the recommended levels. We are pleased that the approval of Tanzeum provides an effective new weekly GLP-1 treatment option for appropriate patients in the US.”

The FDA approval of albiglutide is based on the results of GSK’s comprehensive Phase III Harmony programme, consisting of eight trials and involving over 5,000 patients, over 2,000 of whom were treated with Tanzeum. The Harmony studies evaluated albiglutide against commonly-used classes of type 2 diabetes treatment, including insulin, metformin, glimepiride and pioglitazone, in patients at different stages of the disease, as well as those with renal impairment. 

Following this approval by the FDA, GSK anticipates the US launch of Tanzeum in the third quarter of 2014. 

Albiglutide was licensed by the European Medicines Agency in March 2014, under the brand name Eperzan^®, for use in adult patients with type 2 diabetes.

About diabetes

Diabetes is a global epidemic, affecting 382 million individuals globally, over 20 million of whom are in the US.¹ Up to 95% of these patients have type 2 diabetes.¹ Type 2 diabetes is a life-long, progressive and, in some cases, preventable condition characterized by high blood sugar levels, known as hyperglycemia.  A lack of physical activity, obesity, increasing age, high blood pressure and genetics are known risk factors that can contribute to the development of type 2 diabetes.^2,3  Treatment options include lifestyle changes such as increased physical activity and diet but, as the condition progresses, patients may require the addition of oral and injectable medications to control blood sugar levels and, ultimately, the use of insulin, either daily or with meals.

Important Safety information for Tanzeum (albiglutide)

The following information is taken from the highlights section of the US Prescribing Information.  Please see full Prescribing Information including boxed warning.

BOXED WARNING: RISK OF THYROID C-CELL TUMORS

Thyroid C-cell tumors have been observed in rodent studies with glucagon-like peptide-1 (GLP-1) receptor agonists at clinically relevant exposures. It is unknown whether Tanzeum causes thyroid C-cell tumors, including medullary thyroid carcinoma (MTC), in humans. Tanzeum is contraindicated in patients with a personal or family history of MTC or in patients with Multiple Endocrine Neoplasia syndrome type 2 (MEN 2).

CONTRAINDICATIONS

Do not use in patients with a personal or family history of medullary thyroid carcinoma (MTC) or in patients with Multiple Endocrine Neoplasia syndrome type 2 (MEN 2). Do not use in patients with a prior serious hypersensitivity reaction to albiglutide or to any of the product components.

WARNINGS AND PRECAUTIONS

Pancreatitis: Discontinue promptly if suspected. Do not restart if confirmed. Consider other antidiabetic therapies in patients with a history of pancreatitis.

Hypoglycemia: Can occur when used in combination with insulin secretagogues (e.g. sulfonylureas) or insulin. Consider lowering sulfonylurea or insulin dosage when starting Tanzeum.

Hypersensitivity Reactions: Discontinue Tanzeum if suspected. Monitor and treat promptly per standard of care until signs and symptoms resolve.

Renal Impairment: Monitor renal function in patients with renal impairment reporting severe adverse gastrointestinal reactions.

Macrovascular Outcomes: There have been no clinical trials establishing conclusive evidence of macrovascular risk reduction with Tanzeum or any other antidiabetic drug.

ADVERSE REACTIONS

Adverse reactions, reported in ≥10% of patients treated with Tanzeum and more frequently than in patients on placebo, were upper respiratory tract infection, diarrhea, nausea, and injection site reaction.
