The FDA has approved the dipeptidyl peptidase-4 (DPP-4) inhibitor alogliptin (Nesina – Takeda) for treatment of type 2 diabetes. In addition to the single-ingredient product, the FDA also approved fixed-dose combinations of alogliptin/metformin (Kazano) and alogliptin/pioglitazone (Oseni) for the same indication. Alogliptin is the fourth DPP-4 inhibitor to become available in the US. The other three – saxagliptin (Onglyza), sitagliptin (Januvia), and linagliptin (Tradjenta) – are also available in fixed-dose combinations with metformin.

The FDA has approved Jentadueto XR (Boehringer Ingelheim/Lilly), a once-daily extended-release formulation of the dipeptidyl peptidase-4 (DPP-4) inhibitor linagliptin and the biguanide metformin, for oral treatment of type 2 diabetes. Linagliptin and metformin have been available for years in a twice-daily immediate-release combination (Jentadueto). Once-daily extended-release formulations combining metformin with the DPP-4 inhibitors saxagliptin (Kombiglyze XR) and sitagliptin (Janumet XR) are also available.

Canagliflozin (kan" a gli floe' zin; Invokana – Janssen), a sodium-glucose co-transporter 2 (SGLT2) inhibitor, has been approved by the FDA for oral treatment of type 2 diabetes.

Diet, exercise, and weight loss can improve glycemic control, but almost all patients with type 2 diabetes require antihyperglycemic drug therapy. Treating to a target A1C of <7% while minimizing hypoglycemia is recommended to prevent microvascular complications of diabetes (retinopathy, nephropathy, and neuropathy). An A1C target of <8% may be appropriate for some older patients.

The FDA has approved venetoclax (Venclexta – Abbvie/Genentech), an oral selective BCL-2 inhibitor, for treatment of chronic lymphocytic leukemia (CLL) in patients with a 17p deletion who have received at least one prior therapy.

Venetoclax is the fi rst BCL-2 inhibitor to become available in the US.

The FDA has approved Glyxambi (Boehringer Ingelheim/Lilly), a fixed-dose combination of empagliflozin (Jardiance) and linagliptin (Tradjenta), for oral treatment of type 2 diabetes in adults.
