The FDA announced the approval of Afrezza (insulin human) Inhalation Powder for the improvement of glycemic control in adults with diabetes mellitus.

Afrezza Inhalation Powder is a rapid-acting inhaled insulin administered at the beginning of each meal or within 20 minutes of starting a meal. In patients with type 1 diabetes, Afrezza Inhalation Powder must be taken with a long-acting insulin.

The safety and efficacy of Afrezza were studied in 1,026 patients with type 1 diabetes and 1,991 patients with type 2 diabetes. The efficacy of mealtime Afrezza in type 1 diabetes patients was compared with mealtime insulin aspart, both in combination with basal insulin in a 24-week study.

At Week 24, treatment with basal insulin and mealtime Afrezza showed a mean reduction in HbA1c that met the non-inferiority margin of 0.4%. Afrezza provided a statistically significant less HbA1c reduction than insulin aspart.

Afrezza was also evaluated in adults with type 2 diabetes in combination with oral antidiabetic drugs. The efficacy of mealtime Afrezza in type 2 diabetes patients was compared to placebo inhalation in a 24-week study. At Week 24, treatment with Afrezza in combination with oral antidiabetic drugs provided a mean reduction in HbA1c that was statistically significantly greater vs. the HbA1c reduction seen in the placebo group.
