🎯 Indications and Usage ▾
1 INDICATIONS AND USAGE AFREZZA ® is indicated to improve glycemic control in adult and pediatric patients 6 years of age and older with diabetes mellitus. AFREZZA ® is a rapid acting inhaled human insulin indicated to improve glycemic control in adult and pediatric patients 6 years of age and older with diabetes mellitus. ( 1 ) Limitations of Use : Not recommended for the treatment of diabetic ketoacidosis (DKA) ( 1 ) Not recommended in patients who smoke or who have recently stopped smoking ( 1 ) Limitations of Use: AFREZZA is not recommended for the treatment of diabetic ketoacidosis (DKA) [see Warnings and Precautions ( 5.6 )] .
The safety and effectiveness of AFREZZA in patients who smoke have not been established. The use of AFREZZA is not recommended in patients who smoke or who have recently stopped smoking [see Warnings and Precautions ( 5.5 )].
⏱️ Dosage and Administration ▾
2 DOSAGE AND ADMINISTRATION Only administer via oral inhalation using the AFREZZA inhaler ( 2.2 ) Administer at the beginning of each meal ( 2.2 ) See full prescribing information for the recommended starting mealtime dosage in insulin-naïve patients and patients who are using subcutaneous mealtime insulin, or pre-mixed insulin ( 2.3 ) Modify the mealtime AFREZZA dosage based on the patient's metabolic needs, blood glucose monitoring results, and glycemic control goal ( 2.4 ) If blood glucose control is not achieved with increased AFREZZA dosages, consider discontinuing AFREZZA ( 2.4 )
2.1Lung Function Assessment Prior to Administration AFREZZA is contraindicated in patients with chronic lung disease because of the risk of acute bronchospasm in these patients. Before initiating AFREZZA, perform a medical history, physical examination and spirometry (FEV 1 ) in all patients to identify potential lung disease [see Contraindications ( 4 ) and Warnings and Precautions ( 5.1 )].
2.2Important Administration Information Prior to initiation, train patients and/or their caregiver(s) on proper administration of AFREZZA. After training, adult and pediatric patients aged 10 and older may self-administer AFREZZA if the healthcare provider determines that it is appropriate. Refer patients to the Instructions for Use for detailed instructions and visuals on how to prepare, administer, and store AFREZZA; use the AFREZZA cartridges; and use the AFREZZA inhaler.
Only administer AFREZZA via oral inhalation using the AFREZZA Inhaler. Administer AFREZZA at the beginning of each meal. Administer AFREZZA using a single inhalation per cartridge (if the dose is greater than the contents of a single cartridge, more than one cartridge is needed) [see Dosage and Administration ( 2.3 ), Dosage Forms and Strengths ( 3 )].
To administer AFREZZA: Keep the inhaler level with the white mouthpiece on top and purple base on the bottom after a cartridge has been inserted into the inhaler. Loss of drug effect can occur if the inhaler is turned upside down, held with the mouthpiece pointing down, shaken, or dropped after the cartridge has been inserted but before the dose has been administered. If any of the above occur, replace the cartridge before use.
Hold the inhaler away from the mouth and fully exhale. After the inhaler is placed in the mouth and the lips form a seal, tilt the inhaler down towards the chin while keeping the head level. With the mouth closed around the mouthpiece, inhale deeply through the inhaler.
Hold the breath for as long as comfortable and at the same time remove the inhaler from the mouth. After holding the breath, exhale and continue to breathe normally. The AFREZZA Inhaler can be used for up to 15 days from the date of first use.
After 15 days of use, discard the inhaler and replace it with a new inhaler.
2.3Recommended Starting Mealtime Dosage of AFREZZA Insulin naïve patients The initial dosage of AFREZZA is 4 units inhaled at the beginning of each meal. Switching from Other Mealtime (prandial) Insulin Regimens to AFREZZA When switching from another insulin to AFREZZA, a different insulin dosage may be needed and increased frequency of blood glucose monitoring and monitoring for signs and symptoms of hypoglycemia may be needed [see Warnings and Precautions ( 5.2 , 5.3 ), Clinical Pharmacology ( 12.2 , 12.3 )]. Subcutaneous, Mealtime (prandial) Insulin: Follow the recommendations in Table 1 to convert each injected mealtime insulin dosage (or bolus dosage for patients using insulin pumps) to the recommended mealtime dosage of AFREZZA.
Subcutaneous, Pre-Mixed Insulin: Refer to the prescribing information for the pre-mixed insulin to estimate the mealtime subcutaneous insulin dosage based on the product’s pharmacokinetic and pharmacodynamic properties. Follow the recommendations in Table 1 to convert each estimated injected mealtime dosage to an AFREZZA mealtime dose. If basal insulin is clinically indicated, refer to the prescribing…

⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Hypoglycemia or Hyperglycemia with Changes in Insulin Regimen : Make necessary changes to a patient's insulin regimen under close medical supervision with increased frequency of blood glucose monitoring. For patients with type 2 diabetes mellitus, oral antidiabetic treatment dosage modifications may be needed. ( 5.2 ) Hypoglycemia (may be life-threatening): Increase frequency of glucose monitoring in patients at higher risk for hypoglycemia and those who have reduced symptomatic awareness of hypoglycemia.
( 5.3 ) Decline in Pulmonary Function : Assess pulmonary function (e.g., spirometry (FEV 1 )) at baseline, after 6 months of therapy, and annually, even in the absence of pulmonary symptoms. In patients who have a decline of ≥ 20% in FEV 1 from baseline, consider discontinuing AFREZZA. Consider more frequent monitoring of pulmonary function in patients with pulmonary symptoms ( 5.4 ) Lung Cancer : In patients with active lung cancer, a prior history of lung cancer, or in patients at risk for lung cancer, consider whether the benefits of AFREZZA use outweigh this potential risk.
( 5.5 ) Diabetic Ketoacidosis : In patients at risk for DKA, increase the frequency of glucose monitoring and consider changing to alternate route of insulin delivery. ( 5.6 ) Hypersensitivity Reactions : Severe, life-threatening, generalized allergy, including anaphylaxis, can occur with AFREZZA. If hypersensitivity reactions occur, discontinue AFREZZA, treat per standard of care and monitor until symptoms and signs resolve.
( 5.7 ) Hypokalemia (may be life-threatening): Monitor potassium levels in patients at risk of hypokalemia. ( 5.8 ) Fluid Retention and Heart Failure with Concomitant Use of PPAR-gamma Agonists: Observe for signs and symptoms of heart failure; consider dosage reduction or discontinuation if heart failure occurs. ( 5.9 )
5.1Acute Bronchospasm in Patients with Chronic Lung Disease Because of the risk of acute bronchospasm, AFREZZA is contraindicated in patients with chronic lung disease such as asthma or COPD [see Contraindications ( 4 )] . Before initiating therapy with AFREZZA, evaluate patients with a medical history, physical examination, and spirometry (FEV 1 ) to identify potential underlying lung disease. Acute bronchospasm has been observed in AFREZZA-treated patients with asthma and COPD.
In a study of patients with asthma whose bronchodilators were temporarily withheld for assessment, bronchoconstriction and wheezing following AFREZZA dosing was reported in 29% (5/17) and 0% (0/13) of patients with and without a diagnosis of asthma, respectively. In this study, a mean decline in FEV 1 of 400 mL was observed 15 minutes after a single AFREZZA dose in patients with asthma. In a subset study of 8 patients with COPD, a mean decline in FEV 1 of 200 mL was observed 18 minutes after a single AFREZZA dose.
5.2Hypoglycemia or Hyperglycemia with Changes in Insulin Regimen Changes in an insulin regimen (e.g., insulin strength, manufacturer, injection site or type, or method of administration) may affect glycemic control and predispose to hypoglycemia [see Warnings and Precautions ( 5.3 )] or hyperglycemia. If clinically indicated, make any necessary changes to a patient's insulin regimen under close medical supervision with increased frequency of blood glucose monitoring. For patients with type 2 diabetes mellitus, dosage modifications of concomitant oral antidiabetic treatment may be needed [see Drug Interactions ( 7 )] .
5.3Hypoglycemia Hypoglycemia is the most common adverse reaction associated with insulins, including AFREZZA. Severe hypoglycemia can cause seizures, may be life-threatening, or cause death. Hypoglycemia can impair concentration ability and reaction time; this may place an individual and others at risk in situations where these abilities are important (e.g., driving or operating other machinery).

6 ADVERSE REACTIONS The following serious adverse reactions are described below and elsewhere in the labeling: Acute bronchospasm in patients with chronic lung disease [see Warnings and Precautions ( 5.1 )] Hypoglycemia [see Warnings and Precautions ( 5.3 )] Decline in pulmonary function [see Warnings and Precautions ( 5.4 )] Lung cancer [see Warnings and Precautions ( 5.5 )] Diabetic ketoacidosis [see Warnings and Precautions ( 5.6 )] Hypersensitivity reactions [see Warnings and Precautions ( 5.7 )] The most common adverse reactions associated with AFREZZA (2% or greater incidence) are hypoglycemia, cough, and throat pain or irritation ( 6 ) To report SUSPECTED ADVERSE REACTIONS, contact MannKind at 1-877-323-8505 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Adverse Reactions in Clinical Trials in Adults with Type 1 or Type 2 Diabetes Mellitus The data described below reflect exposure of 3,017 adult patients to AFREZZA and include 1,026 patients with type 1 diabetes mellitus and 1,991 patients with type 2 diabetes mellitus.
The mean exposure duration was 8.2 months for patients with type 1 diabetes mellitus and those with type 2 diabetes mellitus [see Clinical Studies ( 14.2 , 14.3 )] . In the overall population: 1,874 patients with type 1 or type 2 diabetes mellitus were exposed to AFREZZA for 6 months and 724 patients for greater than one year. 620 and 1,254 patients with type 1 or type 2 diabetes mellitus, respectively, were exposed to AFREZZA for up to 6 months.
238 and 486 patients with type 1 or type 2 diabetes mellitus, respectively, were exposed to AFREZZA for greater than one year (median exposure was 1.8 years). AFREZZA was studied in placebo and active-controlled adult trials (n = 3 and n = 10, respectively). The mean age of the adult population was 50 years and 20 patients were older than 75 years of age; 51% of the population were males; 83% were White, 5% were Black or African American, and 2% were Asian; 10% were Hispanic or Latino ethnicity.
At baseline, the type 1 diabetes mellitus population had diabetes mellitus for an average of 17 years and had a mean HbA1c of 8.3%, and the type 2 diabetes mellitus population had diabetes mellitus for an average of 11 years and had a mean HbA1c of 8.8%. At baseline, 33% of the population reported peripheral neuropathy, 32% reported retinopathy and 20% had a history of cardiovascular disease. Table 2 shows the frequency of common adverse reactions, excluding hypoglycemia, associated with the use of AFREZZA in the pool of controlled trials in adults with type 2 diabetes mellitus patients that occurred more commonly on AFREZZA than on placebo and/or comparator and occurred in at least 2% of patients treated with AFREZZA.

👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS
8.1Pregnancy Risk Summary Limited available data with AFREZZA use in pregnant women are insufficient to determine drug-associated risks for adverse developmental outcomes. Available information from published studies with human insulin use during pregnancy has not reported a clear association with human insulin and adverse developmental outcomes ( see Data ). There are risks to the mother and fetus associated with poorly controlled diabetes in pregnancy ( see Clinical Considerations ).
In animal reproduction studies, there were no adverse developmental outcomes with subcutaneous administration of carrier particles (vehicle without insulin) to pregnant rats during organogenesis at doses 21 times the human daily dose of 99 mg AFREZZA, based on AUC (see Data ) . The estimated background risk of major birth defects is 6-10% in women with pre-gestational diabetes with HbA1c >7 and has been reported to be as high as 20-25% in women with HbA1c >10. The estimated background risk of miscarriage for the indicated population is unknown.
In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. Clinical Considerations Disease-associated maternal and/or embryo/fetal risk Poorly controlled diabetes in pregnancy increases the maternal risk for DKA, pre-eclampsia, spontaneous abortions, preterm delivery, stillbirth, and delivery complications. Poorly controlled diabetes increases the fetal risk for major birth defects, stillbirth, and macrosomia- related morbidity.
Data Human Data There are limited data with AFREZZA use in pregnant women. Published data do not report a clear association with human insulin and major birth defects, miscarriage, or adverse maternal or fetal outcomes when human insulin is used during pregnancy. However, these studies cannot definitely establish the absence of any risk because of methodological limitations including small sample size and lack of blinding.
Animal Data In pregnant rats given subcutaneous doses of 10, 30, and 100 mg/kg/day of carrier particles (vehicle without insulin) from gestation day 6 through 17 (organogenesis), no major malformations were observed at doses up to 100 mg/kg/day (21 times the human systemic exposure at a daily dose of 99 mg AFREZZA, based on AUC). In pregnant rabbits given subcutaneous doses of 2, 10, and 100 mg/kg/day of carrier particles (vehicle without insulin) from gestation day 7 through 19 (organogenesis), adverse maternal effects were observed in all dose groups (at human systemic exposure following a daily dose of 99 mg AFREZZA, based on AUC).
In pregnant rats given subcutaneous doses of 10, 30, and 100 mg/kg/day of carrier particles (vehicle without insulin) from gestation day 7 through lactation day 20 (weaning), decreased epididymis and testes weights were observed in F1 male offspring, however, no decrease in fertility was noted, and impaired learning were observed in F1 pups at > 30 mg/kg/day (6 times the human systemic exposure at a daily dose of 99 mg AFREZZA, based on AUC).
8.2Lactation Risk Summary There are no data on the presence of AFREZZA in human milk, the effects on the breastfed infant, or the effects on milk production. One small published study reported that exogenous subcutaneous insulin was present in human milk. No adverse effects in infants were noted.
The carrier particles are present in rat milk ( see Data ). Potential adverse reactions that are related to inhalational administration of AFREZZA are unlikely to be associated with potential exposure of AFREZZA through breast milk. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for AFREZZA and any potential adverse effects on the breastfed infant from AFREZZA or from the underlying maternal condition.
Data Subcutaneous administration of the carrier particle in lactating rats resulted in excre…

🧒 Pediatric Use ▾
8.4Pediatric Use The safety and effectiveness of AFREZZA to improve glycemic control have been established in pediatric patients 6 years of age and older with diabetes mellitus. Use of AFREZZA for this indication is supported by evidence from an adequate and well controlled trial in pediatric patients aged 6 years and older with type 1 or type 2 diabetes mellitus and from trials in adults with type 1 or type 2 diabetes mellitus [see Adverse Reactions ( 6.1 ), Clinical Studies ( 14.2 , 14.3 , 14.4 )] . The overall safety profile in pediatric patients was similar to adults [see Adverse Reactions ( 6.1 )] .
The safety and effectiveness of AFREZZA have not been established in pediatric patients less than 6 years of age.
🧓 Geriatric Use ▾
8.5Geriatric Use In the AFREZZA clinical studies , 671 (12%) patients were 65 years of age or older, of which 42 (0.8%) were 75 years of age or older. In these studies, 381 (13%) of AFREZZA-treated patients were 65 years of age or older, of which 20 (0.7%) were 75 years of age or older. No overall differences in effectiveness of AFREZZA have been observed between patients 65 years of age and older and younger adult patients [see Clinical Studies ( 14 )] .
Clinical studies of AFREZZA did not include sufficient numbers of patients 65 years of age and older to determine whether there were differences in safety between these patients and younger adult patients. Pharmacokinetic and pharmacodynamic studies to assess the effect of age on pharmacokinetics or pharmacodynamics on insulin human, respectively, have not been conducted.
🆘 Overdosage ▾
10 OVERDOSAGE Excess insulin administration may cause hypoglycemia and hypokalemia [see Warnings and Precautions ( 5.3 , 5.8 )] . Mild episodes of hypoglycemia due to insulin overdose can usually be treated with oral glucose. Adjustments in drug dosage, meal patterns, or exercise, may be needed.
Severe episodes of hypoglycemia (due to insulin overdose) with coma, seizure, or neurologic impairment may be treated with intramuscular or subcutaneous glucagon or concentrated intravenous glucose. After apparent clinical recovery from hypoglycemia, continued observation and additional carbohydrate intake may be necessary to avoid recurrence of hypoglycemia. Hypokalemia should be corrected appropriately.
In the event of an overdose of AFREZZA, consider contacting the Poison Help line (1-800-222-1222) or a medical toxicologist for additional overdosage management recommendations.
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Insulin lowers blood glucose levels in adult patients with diabetes mellitus by stimulating peripheral glucose uptake by skeletal muscle and fat, and by inhibiting hepatic glucose production. Insulin inhibits lipolysis in adipocytes, inhibits proteolysis, and enhances protein synthesis.
12.2Pharmacodynamics The time course of insulin action (i.e., glucose lowering) may vary considerably in different patients or within the same patient, or when switching from subcutaneous mealtime insulin to AFREZZA. The average pharmacodynamic profile [i.e., glucose lowering effect measured by glucose infusion rate (GIR) over time in a euglycemic clamp study] after administration of a single AFREZZA dose of 4, 12, and 48 units in 30 patients with type 1 diabetes mellitus is shown in Figure 2(A) , and key characteristics regarding the timing of the effects are described in Table 7 : Table 7.
Timing of Insulin Effect (i.e., mean pharmacodynamics effect) After Administration of a Single AFREZZA Dose in Patients (N=30) with Type 1 Diabetes Mellitus Parameter for Insulin Effect AFREZZA 4 units AFREZZA 12 units AFREZZA 48 units Time to first measurable effect ~12 minutes ~12 minutes ~12 minutes Time to peak effect ~35 minutes ~45 minutes ~55 minutes Time for effect to return to baseline ~90 minutes ~180 minutes ~270 minutes Figure 2. Results After Administration of AFREZZA 4, 12, and 48 Units in Patients with Type 1 Diabetes Mellitus (N=30) A) Mean Insulin Effect (Baseline-Corrected Glucose Infusion Rate); and B) Pharmacokinetic (Baseline-Corrected Serum Insulin Concentration Profiles) On average, the pharmacodynamics effect of AFREZZA, measured as area under the glucose infusion rate – time curve (AUC GIR) increased linearly with doses up to 48 units (106, 387, and 1581 mg/kg for 4, 12, and 48 units doses, respectively).
Intrapatient variability in AUC GIR and GIRmax was approximately 28% (95% CI 21-42%) and 27% (95% CI 20-40%), respectively. Figure 2
12.3Pharmacokinetics The area under the plasma concentration versus time curve (AUC) of insulin increased dose proportionally up to 48 units. Intrapatient variability of AUC and peak concentration (C max ) of insulin was approximately 16% (95% CI 12-23%) and 21% (95% CI 16-30%), respectively. Absorption The pharmacokinetic profiles for orally inhaled AFREZZA 4, 12, and 48 units from a study in 30 patients with type 1 diabetes mellitus are shown in Figure 2(B) .
A higher maximum plasma insulin concentration was achieved at an earlier timepoint in this study when patients were switched from subcutaneous mealtime insulin to AFREZZA [see Dosage and Administration ( 2.3 )]. The time to maximum serum insulin concentration (t max ) ranged from 10-20 minutes after oral inhalation of 4 to 48 units of AFREZZA. Elimination The apparent terminal half-life ranged from 120 to 206 minutes.
Serum insulin concentrations declined to baseline by approximately 60 to 240 minutes. Metabolism and Excretion The metabolism and excretion of AFREZZA are comparable to regular human insulin. Carrier Particles Clinical pharmacology studies showed that carrier particles [see Description ( 11.1 )] are not metabolized and are eliminated unchanged in the urine following the lung absorption.
Following oral inhalation of AFREZZA, a mean of 39% of the inhaled dose of carrier particles was distributed to the lungs and a mean of 7% of the dose was swallowed. The swallowed fraction was not absorbed from the GI tract and was eliminated unchanged in the feces. Specific Populations Pediatric Patients In pediatric patients aged 8 years and older, insulin serum concentration profiles (T max and time decline to baseline) showed a similar time course between adult and pediatric patients following administration of AFREZZA.
Insulin Cmax and AUC increased in a dose-dependent manner following a single dose of 4 units to 12 units. Drug Interaction Studies Bronchodilators and Inhaled Steroids Albutero…
🧬 Mechanism of Action ▾
12.1Mechanism of Action Insulin lowers blood glucose levels in adult patients with diabetes mellitus by stimulating peripheral glucose uptake by skeletal muscle and fat, and by inhibiting hepatic glucose production. Insulin inhibits lipolysis in adipocytes, inhibits proteolysis, and enhances protein synthesis.
