FDA Triple Play Against Type 2 Diabetes

FDA Triple Play Against Type 2 Diabetes

January was a banner month for type 2 diabetes drugs, with the FDA approving the new dipeptidyl peptidase-4 (DPP-4) inhibitor alogliptin as monotherapy (Nesima) and, simultaneously, in combination with metformin (Kazano) and pioglitzone (Oseni). DPP-4 inhibitors block the degradation of active incretin hormones (GLP-1 and GIP), stimulating the release of insulin in a glucose-dependent manner and decreasing levels of circulating glucagon.

• Alogliptin was approved based on the results of 14 clinical trials that included about 8,500 people with T2DM. The drug improved HbA1C by a range of 0.4% to 0.6% compared with placebo.

• The alogliptin and metformin combination was approved based on data from 4 trials that included more than 2,500 patients with T2DM. It improved HbA1C by 1.1% compared with alogliptin alone and by 0.5% compared with metformin alone.

• Alogliptin and pioglitazone in fixed-dose combination was approved based on data from 4 clinical trials including more than 1,500 patients with T2DM. Combining alogliptin with pioglitazone reduced HbA1c by 0.4% to 0.6% compared with pioglitazone alone and by 0.4% to 0.9% compared with alogliptin alone.

Alogliptin is the fourth DPP-4 inhibitor to win FDA approval, joining sitagliptin (Januvia), saxagliptin (Onglyza), and linagliptin (Tradjenta). As condition of the approval, manufacturer Takeda will be required to conduct 5 postmarketing studies of alogliptin, including one focusing on cardiovascular events as well as "an enhanced pharmacovigilance program" targeting liver abnormalities, pancreatitis, and hypersensitivity reactions.
