Drug: Afrezza

AFREZZA Cartridges AFREZZA consists of single-use plastic cartridges filled with a white powder containing insulin (human), which is administered via oral inhalation using the AFREZZA Inhaler only. AFREZZA cartridges contain human insulin produced by recombinant DNA technology utilizing a non-pathogenic laboratory strain of Escherichia coli (K12). Chemically, human insulin has the empirical formula C257H383N65O77S6 and a molecular weight of 5808. Human insulin has the following primary amino acid sequence: Insulin is adsorbed onto carrier particles consisting of fumaryl diketopiperazine (FDKP) and polysorbate 80. AFREZZA Inhalation Powder is a dry powder supplied as 4 unit, 8 unit or 12 unit cartridges. The 4 unit cartridge contains 0.35 mg of insulin. The 8 unit cartridge contains 0.7 mg of insulin. The 12 unit cartridge contains 1.0 mg of insulin. AFREZZA Inhaler The AFREZZA Inhaler is breath-powered by the patient. When the patient inhales through the device, the powder is aerosolized and delivered to the lung. The amount of AFREZZA delivered to the lung will depend on individual patient factors.

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]
  • Hypoglycemia [see WARNINGS AND PRECAUTIONS]
  • Decline in pulmonary function [see WARNINGS AND PRECAUTIONS]
  • Lung cancer [see WARNINGS AND PRECAUTIONS]
  • Diabetic ketoacidosis [see WARNINGS AND PRECAUTIONS]
  • Hypersensitivity reactions [see WARNINGS AND PRECAUTIONS]
Clinical Trials Experience Because clinical trials are conducted under widely varying designs, the incidence of adverse reactions reported in one clinical trial may not be easily compared to the incidence reported in another clinical trial, and may not reflect what is observed in clinical practice. The data described below reflect exposure of 3017 patients to AFREZZA and include 1026 patients with type 1 diabetes and 1991 patients with type 2 diabetes. The mean exposure duration was 8.17 months for the overall population and 8.16 months and 8.18 months for type 1 and 2 diabetes patients, respectively. In the overall population, 1874 were exposed to AFREZZA for 6 months and 724 for greater than one year. 620 and 1254 patients with type 1 and type 2 diabetes, respectively, were exposed to AFREZZA for up to 6 months. 238 and 486 patients with type 1 and type 2 diabetes, respectively, were exposed to AFREZZA for greater than one year (median exposure = 1.8 years). AFREZZA was studied in placebo and active-controlled trials (n = 3 and n = 10, respectively). The mean age of the population was 50.2 years and 20 patients were older than 75 years of age. 50.8% of the population were men; 82.6% were White, 1.8% were Asian, and 4.9% were Black or African American. 9.7% were Hispanic. At baseline, the type 1 diabetes population had diabetes for an average of 16.6 years and had a mean HbA1c of 8.3%, and the type 2 diabetes population had diabetes for an average of 10.7 years and had a mean HbA1c of 8.8%. At baseline, 33.4% of the population reported peripheral neuropathy, 32.0% reported retinopathy and 19.6% had a history of cardiovascular disease. Table 1 shows common adverse reactions, excluding hypoglycemia, associated with the use of AFREZZA in the pool of controlled trials in type 2 diabetes patients. These adverse reactions were not present at baseline, occurred more commonly on AFREZZA than on placebo and/or comparator and occurred in at least 2% of patients treated with AFREZZA.

The incidence of severe and non-severe hypoglycemia of AFREZZA versus placebo in patients with type 2 diabetes is shown in Table 3. A hypoglycemic episode was recorded if a patient reported symptoms of hypoglycemia with or without a blood glucose value consistent with hypoglycemia. Severe hypoglycemia was defined as an event with symptoms consistent with hypoglycemia requiring the assistance of another person and associated with either a blood glucose value consistent with hypoglycemia or prompt recovery after treatment for hypoglycemia.

  Placebo
(N=176) AFREZZA
(N=177) Severe Hypoglycemia 1.7% 5.1% Non-Severe Hypoglycemia 30% 67% Cough Approximately 27% of patients treated with AFREZZA reported cough, compared to approximately 5.2% of patients treated with comparator. In clinical trials, cough was the most common reason for discontinuation of AFREZZA therapy (2.8% of AFREZZA-treated patients). Pulmonary Function Decline In clinical trials lasting up to 2 years, excluding patients with chronic lung disease, patients treated with AFREZZA had a 40 mL (95% CI: -80, -1) greater decline from baseline in forced expiratory volume in one second (FEV1) compared to patients treated with comparator anti-diabetes treatments. The decline occurred during the first 3 months of therapy and persisted over 2 years (Figure 2). A decline in FEV1 of ≥ 15% occurred in 6% of AFREZZA-treated subjects compared to 3% of comparator-treated subjects. Figure 2: Mean (+/-SE) Change in FEV1 (Liters) from Baseline for Type 1 and Type 2 Diabetes Patients
Weight Gain Weight gain may occur with some insulin therapies, including AFREZZA. Weight gain has been attributed to the anabolic effects of insulin and the decrease in glycosuria. In a clinical trial of patients with type 2 diabetes [see Clinical Studies], there was a mean 0.49 kg weight gain among AFREZZA-treated patients compared with a mean 1.13 kg weight loss among placebo-treated patients. Antibody Production Increases in anti-insulin antibody concentrations have been observed in patients treated with AFREZZA. Increases in anti-insulin antibodies are observed more frequently with AFREZZA than with subcutaneously injected mealtime insulins. Presence of antibody did not correlate with reduced efficacy, as measured by HbA1c and fasting plasma glucose, or specific adverse reactions.

Route Of Administration AFREZZA should only be administered via oral inhalation using the AFREZZA Inhaler. AFREZZA is administered using a single inhalation per cartridge. Dosage Information Administer AFREZZA at the beginning of the meal. Dosage adjustment may be needed when switching from another insulin to AFREZZA [see WARNINGS AND PRECAUTIONS]. Starting Mealtime Dose
  • Insulin Na├»ve Individuals: Start on 4 units of AFREZZA at each meal.
  • Individuals Using Subcutaneous Mealtime (Prandial) Insulin: Determine the appropriate AFREZZA dose for each meal by converting from the injected dose using Figure 1.
  • Individuals Using Subcutaneous Pre-mixed Insulin: Estimate the mealtime injected dose by dividing half of the total daily injected pre-mixed insulin dose equally among the three meals of the day. Convert each estimated injected mealtime dose to an appropriate AFREZZA dose using Figure 1. Administer half of the total daily injected pre-mixed dose as an injected basal insulin dose.
Figure 1: Mealtime AFREZZA Dose Conversion Table
Mealtime Dose Adjustment Adjust the dosage of AFREZZA based on the individual's metabolic needs, blood glucose monitoring results and glycemic control goal. Dosage adjustments may be needed with changes in physical activity, changes in meal patterns (i.e., macronutrient content or timing of food intake), changes in renal or hepatic function or during acute illness [see WARNINGS AND PRECAUTIONS, and Use In Specific Populations]. Carefully monitor blood glucose control in patients requiring high doses of AFREZZA. If, in these patients, blood glucose control is not achieved with increased AFREZZA doses, consider use of subcutaneous mealtime insulin. AFREZZA Administration For Doses Exceeding 12 Units For AFREZZA doses exceeding 12 units, inhalations from multiple cartridges are necessary. To achieve the required total mealtime dose, patients should use a combination of 4 unit, 8 unit and 12 unit cartridges. Examples of cartridge combinations for doses of up to 24 units are shown in Figure 1. For doses above 24 units, combinations of different multiple cartridges can be used. Dosage Adjustment Due To Drug Interactions Dosage adjustment may be needed when AFREZZA is coadministered with certain drugs [see DRUG INTERACTIONS]. Lung 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 (FEV1) in all patients to identify potential lung disease [see CONTRAINDICATIONS and WARNINGS AND PRECAUTIONS]. Important Administration Instructions See Patient Instructions for Use for complete administration instructions with illustrations. 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, the cartridge should be replaced before use.

Drugs That May Increase The Risk Of Hypoglycemia The risk of hypoglycemia associated with AFREZZA use may be increased with antidiabetic agents, ACE inhibitors, angiotensin II receptor blocking agents, disopyramide, fibrates, fluoxetine, monoamine oxidase inhibitors, pentoxifylline, pramlintide, propoxyphene, salicylates, somatostatin analogs (e.g., octreotide), and sulfonamide antibiotics. Dose adjustment and increased frequency of glucose monitoring may be required when AFREZZA is co-administered with these drugs. Drugs That May Decrease The Blood Glucose Lowering Effect Of AFREZZA The glucose lowering effect of AFREZZA may be decreased when co-administered with atypical antipsychotics (e.g., olanzapine and clozapine), corticosteroids, danazol, diuretics, estrogens, glucagon, isoniazid, niacin, oral contraceptives, phenothiazines, progestogens (e.g., in oral contraceptives), protease inhibitors, somatropin, sympathomimetic agents (e.g., albuterol, epinephrine, terbutaline) and thyroid hormones. Dose adjustment and increased frequency of glucose monitoring may be required when AFREZZA is co-administered with these drugs. Drugs That May Increase Or Decrease The Blood Glucose Lowering Effect Of AFREZZA The glucose lowering effect of AFREZZA may be increased or decreased when coadministered with alcohol, beta-blockers, clonidine, and lithium salts. Pentamidine may cause hypoglycemia, which may sometimes be followed by hyperglycemia. Dose adjustment and increased frequency of glucose monitoring may be required when AFREZZA is coadministered with these drugs. Drugs That May Affect Hypoglycemia Signs And Symptoms The signs and symptoms of hypoglycemia may be blunted when beta-blockers, clonidine, guanethidine, and reserpine are co-administered with AFREZZA.

Excess insulin administration may cause hypoglycemia and hypokalemia [see WARNINGS AND PRECAUTIONS]. Mild episodes of hypoglycemia can usually be treated with oral glucose. Adjustments in drug dosage, meal patterns, or exercise, may be needed. Severe episodes of hypoglycemia with coma, seizure, or neurologic impairment may be treated with intramuscular / 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 must be corrected appropriately.

Acute 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]. Before initiating therapy with AFREZZA, evaluate all patients with a medical history, physical examination and spirometry (FEV1) to identify potential underlying lung disease. Acute bronchospasm has been observed following AFREZZA dosing in patients with asthma and patients with COPD. In a study of patients with asthma, bronchoconstriction and wheezing following AFREZZA dosing was reported in 29% (5 out of 17) and 0% (0 out of 13) of patients with and without a diagnosis of asthma, respectively. In this study, a mean decline in FEV1 of 400 mL was observed 15 minutes after a single dose in patients with asthma. In a study of patients with COPD (n=8), a mean decline in FEV1 of 200 mL was observed 18 minutes after a single dose of AFREZZA. The long-term safety and efficacy of AFREZZA in patients with chronic lung disease has not been established. Changes In Insulin Regimen Glucose monitoring is essential for patients receiving insulin therapy. Changes in insulin strength, manufacturer, type, or method of administration may affect glycemic control and predispose to hypoglycemia [see Hypoglycemia] or hyperglycemia. These changes should be made under close medical supervision and the frequency of blood glucose monitoring should be increased. Concomitant oral antidiabetic treatment may need to be adjusted. Hypoglycemia 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). The timing of hypoglycemia usually reflects the time-action profile of the administered insulin formulation. AFREZZA has a distinct time action profile [see CLINICAL PHARMACOLOGY], which impacts the timing of hypoglycemia. Hypoglycemia can happen suddenly and symptoms may differ across individuals and change over time in the same individual. Symptomatic awareness of hypoglycemia may be less pronounced in patients with longstanding diabetes, in patients with diabetic nerve disease, in patients using certain medications [see DRUG INTERACTIONS], or in patients who experience recurrent hypoglycemia. Other factors which may increase the risk of hypoglycemia include changes in meal pattern (e.g., macronutrient content or timing of meals), changes in level of physical activity, or changes to co-administered medication [see DRUG INTERACTIONS]. Patients with renal or hepatic impairment may be at higher risk of hypoglycemia [see Use in Specific Populations]. Risk Mitigation Strategies for Hypoglycemia Patients and caregivers must be educated to recognize and manage hypoglycemia. Self-monitoring of blood glucose plays an essential role in the prevention and management of hypoglycemia. In patients at higher risk for hypoglycemia and patients who have reduced symptomatic awareness of hypoglycemia, increased frequency of blood glucose monitoring is recommended. Decline In Pulmonary Function AFREZZA causes a decline in lung function over time as measured by FEV1. In clinical trials excluding patients with chronic lung disease and lasting up to 2 years, AFREZZA-treated patients experienced a small [40 mL (95% CI: -80, -1)] but greater FEV1 decline than comparator-treated patients. The FEV1 decline was noted within the first 3 months, and persisted for the entire duration of therapy (up to 2 years of observation). In this population, the annual rate of FEV1 decline did not appear to worsen with increased duration of use. The effects of AFREZZA on pulmonary function for treatment duration longer than 2 years has not been established. There are insufficient data in long term studies to draw conclusions regarding reversal of the effect on FEV1 after discontinuation of AFREZZA. The observed changes in FEV1 were similar in patients with type 1 and type 2 diabetes. Assess pulmonary function (e.g., spirometry) at baseline, after the first 6 months of therapy, and annually thereafter, even in the absence of pulmonary symptoms. In patients who have a decline of ≥ 20% in FEV1 from baseline, consider discontinuing AFREZZA. Consider more frequent monitoring of pulmonary function in patients with pulmonary symptoms such as wheezing, bronchospasm, breathing difficulties, or persistent or recurring cough. If symptoms persist, discontinue AFREZZA. [see ADVERSE REACTIONS]. Lung Cancer In clinical trials, two cases of lung cancer, one in controlled trials and one in uncontrolled trials (2 cases in 2,750 patient-years of exposure), were observed in participants exposed to AFREZZA while no cases of lung cancer were observed in comparators (0 cases in 2,169 patient-years of exposure). In both cases, a prior history of heavy tobacco use was identified as a risk factor for lung cancer. Two additional cases of lung cancer (squamous cell) occurred in non-smokers exposed to AFREZZA and were reported by investigators after clinical trial completion. These data are insufficient to determine whether AFREZZA has an effect on lung or respiratory tract tumors. 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. Diabetic Ketoacidosis In clinical trials enrolling subjects with type 1 diabetes, diabetic ketoacidosis (DKA) was more common in subjects receiving AFREZZA (0.43%; n=13) than in subjects receiving comparators (0.14%; n=3). In patients at risk for DKA, such as those with an acute illness or infection, increase the frequency of glucose monitoring and consider delivery of insulin using an alternate route of administration if indicated [see Limitations of Use]. Hypersensitivity Reactions Severe, life-threatening, generalized allergy, including anaphylaxis, can occur with insulin products, including AFREZZA. If hypersensitivity reactions occur, discontinue AFREZZA, treat per standard of care and monitor until symptoms and signs resolve [see ADVERSE REACTIONS]. AFREZZA is contraindicated in patients who have had hypersensitivity reactions to AFREZZA or any of its excipients [see CONTRAINDICATIONS]. Hypokalemia All insulin products, including AFREZZA, cause a shift in potassium from the extracellular to intracellular space, possibly leading to hypokalemia. Untreated hypokalemia may cause respiratory paralysis, ventricular arrhythmia, and death. Monitor potassium levels in patients at risk for hypokalemia (e.g., patients using potassium-lowering medications, patients taking medications sensitive to serum potassium concentrations and patients receiving intravenously administered insulin). Fluid Retention And Heart Failure With Concomitant Use Of PPAR-gamma Agonists Thiazolidinediones (TZDs), which are peroxisome proliferator-activated receptor (PPAR)gamma agonists, can cause dose-related fluid retention, particularly when used in combination with insulin. Fluid retention may lead to or exacerbate heart failure. Patients treated with insulin, including AFREZZA, and a PPAR-gamma agonist should be observed for signs and symptoms of heart failure. If heart failure develops, it should be managed according to current standards of care, and discontinuation or dose reduction of the PPAR-gamma agonist must be considered. Patient Counseling Information See FDA-approved patient labeling (Medication Guide) Instructions Instruct patients to read the Medication Guide before starting AFREZZA therapy and to reread it each time the prescription is renewed, because information may change. Instruct patients to inform their healthcare provider or pharmacist if they develop any unusual symptom, or if any known symptom persists or worsens. Inform patients of the potential risks and benefits of AFREZZA and of alternative modes of therapy. Inform patients about the importance of adherence to dietary instructions, regular physical activity, periodic blood glucose monitoring and HbA1c testing, recognition and management of hypoglycemia and hyperglycemia, and assessment for diabetes complications. Advise patients to seek medical advice promptly during periods of stress such as fever, trauma, infection, or surgery, as medication requirements may change. Instruct patients to use AFREZZA only with the AFREZZA inhaler. Inform patients that the most common adverse reactions associated with the use of AFREZZA are hypoglycemia, cough, and throat pain or irritation. Advise women with diabetes to inform their physician if they are pregnant or are planning to become pregnant while using AFREZZA. Acute Bronchospasm in Patients with Chronic Lung Disease Advise patients to inform their physicians if they have a history of lung disease, because AFREZZA should not be used in patients with chronic lung disease (e.g., asthma, COPD, or other chronic lung disease(s)) [see CONTRAINDICATIONS and WARNINGS AND PRECAUTIONS]. Advise patients that if they experience any respiratory difficulty after inhalation of AFREZZA, they should report it to their physician immediately for assessment. Hypoglycemia Instruct patients on self-management procedures including glucose monitoring, proper inhalation technique, and management of hypoglycemia and hyperglycemia especially at initiation of AFREZZA therapy. Instruct patients on handling of special situations such as intercurrent conditions (illness, stress, or emotional disturbances), an inadequate or skipped insulin dose, inadvertent administration of an increased insulin dose, inadequate food intake, and skipped meals. Instruct patients on the management of hypoglycemia. Inform patients that their ability to concentrate and react may be impaired as a result of hypoglycemia. Advise patients who have frequent hypoglycemia or reduced or absent warning signs of hypoglycemia to use caution when driving or operating machinery [see WARNINGS AND PRECAUTIONS]. Decline in Pulmonary Function and Monitoring Inform patients that AFREZZA can cause a decline in lung function and their lung function will be evaluated by spirometry before initiation of AFREZZA treatment [see WARNINGS AND PRECAUTIONS]. Lung Cancer Inform patients to promptly report any signs or symptoms potentially related to lung cancer [see WARNINGS AND PRECAUTIONS]. Diabetic Ketoacidosis Instruct patients to carefully monitor their blood glucose during illness, infection, and other risk situations for diabetic ketoacidosis and to contact their healthcare provider if their blood glucose control worsens [see WARNINGS AND PRECAUTIONS]. Hypersensitivity Reactions Advise patients that hypersensitivity reactions can occur with insulin therapy including AFREZZA. Inform patients on the symptoms of hypersensitivity reactions [see WARNINGS AND PRECAUTIONS]. Nonclinical Toxicology Carcinogenesis, Mutagenesis, Impairment Of Fertility In a 104 week carcinogenicity study, rats were given doses up to 46 mg/kg/day of the carrier and up to 1.23 mg/kg/day of insulin, by nose-only inhalation. No increased incidence of tumors was observed at systemic exposures equivalent to the insulin at a maximum daily AFREZZA dose of 99 mg based on a comparison of relative body surface areas across species. In a 26 week carcinogenicity study, transgenic mice (Tg-ras-H2) given doses up to 75 mg/kg/day of carrier and up to 5 mg/kg/day of AFREZZA. No increased incidence of tumors was observed. AFREZZA was not genotoxic in Ames bacterial mutagenicity assay and in the chromosome aberration assay, using human peripheral lymphocytes with or without metabolic activation. The carrier alone was not genotoxic in the in vivo mouse micronucleus assay. In female rats given subcutaneous doses of 10, 30, and 100 mg/kg/day of carrier (vehicle without insulin) beginning 2 weeks prior to mating until gestation day 7, there were no adverse effects on male fertility at doses up to 100 mg/kg/day (a systemic exposure 14-21 times that following the maximum daily AFREZZA dose of 99 mg based on AUC). In female rats there was increased pre- and post-implantation loss at 100 mg/kg/day but not at 30 mg/kg/day (14-21 times higher systemic exposure than the maximum daily AFREZZA dose of 99 mg based on AUC). Use In Specific Populations Pregnancy Teratogenic Effects Pregnancy Category C AFREZZA has not been studied in pregnant women. AFREZZA should not be used during pregnancy unless the potential benefit justifies the potential risk to the fetus. 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 up to 100 mg/kg/day (a systemic exposure 14-21 times the human systemic exposure, resulting from the maximum recommended 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 at all dose groups (at human systemic exposure following a 99 mg AFREZZA dose, 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, however, no decrease in fertility was noted, and impaired learning were observed in pups at ≥ 30 mg/kg/day (a systemic exposure 6 times human systemic exposure at the maximum daily AFREZZA dose of 99 mg based on AUC). Nursing Mothers Many drugs are excreted in human milk. A study in rats indicated that the carrier is excreted in milk at approximately 10% of maternal exposure levels. It is therefore highly likely that the insulin and carrier in AFREZZA is excreted in human milk. A decision should be made whether to discontinue nursing or suspend use of the drug since AFREZZA has not been studied in lactating women. Pediatric Use AFREZZA has not been studied in patients younger than 18 years of age. Geriatric Use In the AFREZZA clinical studies, 381 patients were 65 years of age or older, of which 20 were 75 years of age or older. No overall differences in safety or effectiveness were observed between patients over 65 and younger patients. Pharmacokinetic/pharmacodynamic studies to assess the effect of age have not been conducted. Hepatic Impairment The effect of hepatic impairment on the pharmacokinetics of AFREZZA has not been studied. Frequent glucose monitoring and dose adjustment may be necessary for AFREZZA in patients with hepatic impairment [see WARNINGS AND PRECAUTIONS]. Renal Impairment The effect of renal impairment on the pharmacokinetics of AFREZZA has not been studied. Some studies with human insulin have shown increased circulating levels of insulin in patients with renal failure. Frequent glucose monitoring and dose adjustment may be necessary for AFREZZA in patients with renal impairment [see WARNINGS AND PRECAUTIONS]. Last reviewed on RxList: 5/5/2015
