Popis: Afrezza® (insulin human) inhalation powder is a rapid-acting Technosphere® insulin (TI) administered via a breath-powered oral inhaler to patients with diabetes requiring prandial insulin. TI, a dry powdered formulation of recombinant human insulin adsorbed onto a proprietary carrier, is designed to deliver insulin to the deep lung, at the level of the alveoli, where it is absorbed into the systemic circulation. In a randomized, open-label, multinational, phase III trial (trial 171) in type 1 diabetes (T1DM) patients, prandial TI via the Gen2 inhaler provided noninferior glycated haemoglobin (HbA1c) lowering compared with prandial subcutaneous insulin aspart. Although TI was associated with less HbA1c lowering, it provided significantly lower fasting plasma glucose levels and significantly less hypoglycaemia and bodyweight gain compared with insulin aspart. In a randomized, double-blind, placebo-controlled, multinational, phase III trial (trial 175) in type 2 diabetes (T2DM) patients, prandial TI via the Gen2 inhaler provided superior HbA1c lowering compared with inhaled placebo. Cough was the most commonly occurring non-hypoglycaemia adverse event across both studies. In a pooled analysis of tolerability data from phase II and III studies, the most commonly occurring non-hypoglycaemia adverse events in T1DM and T2DM patients were cough and throat pain/irritation. However, cough was generally mild, dry and decreased over time. In addition, treatment with TI was associated with positive patient-reported outcomes. Insulin human inhalation powder is an effective and generally well-tolerated agent for the prandial treatment of hyperglycaemia in T1DM and T2DM patients and may provide a solution to insulin initiation barriers such as injection phobia, concerns of bodyweight gain and concerns of hypoglycaemia.
