NOVOLOG MIX 70/30

6 ADVERSE REACTIONS The following adverse reactions are also discussed elsewhere: • Hypoglycemia [ see Warnings and Precautions (5.3) ] • Hypoglycemia Due to Medication Errors [ see Warnings and Precautions (5.4) ] • Hypersensitivity reactions [ see Warnings and Precautions (5.5) ] • Hypokalemia [ see Warnings and Precautions (5.6) ] Adverse reactions observed with insulin therapy include hypoglycemia, allergic reactions, local injection site reactions, lipodystrophy, rash and pruritus (6) . To report SUSPECTED ADVERSE REACTIONS, contact Novo Nordisk Inc. at 1-800-727-6500 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trial Experience Clinical trials are conducted under widely varying designs, therefore, the adverse reaction rates reported in one clinical trial may not be easily compared to those rates reported in another clinical trial, and may not reflect the rates actually observed in clinical practice. The data in: • Table 1 reflects the exposure of 55 patients with type 1 diabetes to NOVOLOG MIX 70/30 with a mean exposure duration of three months. The mean age was 43 years old. Sixty-four percent were male and 100% were White. The mean body mass index (BMI) was 26.1 kg/m 2 . The mean duration of diabetes was 15 years. • Table 2 reflects the exposure of 85 patients with type 2 diabetes to NOVOLOG MIX 70/30 with a mean exposure duration of three months. The mean age was 63 years old. Fifty-four percent were male and 100% were White. The mean body mass index (BMI) was 28.1 kg/m 2 . The mean duration of diabetes was 15 years. Common adverse reactions were defined as events that occurred in ≥5%, excluding hypoglycemia, of the population studied. Common adverse reactions that occurred for NOVOLOG MIX 70/30-treated patients with type 1 diabetes mellitus and type 2 diabetes mellitus are listed in Table 1 and Table 2, respectively. The trial was a three-month, open-label trial in patients with type 1 or type 2 diabetes who were treated twice daily (before breakfast and before supper) with NOVOLOG MIX 70/30. Table 1: Adverse Reactions that Occurred in ≥ 5% of Type 1 Diabetes Mellitus Adult Patients Treated with NOVOLOG MIX 70/30 NOVOLOG MIX 70/30 (n=55) Preferred Term N % Hypoglycemia 38 69 Headache 19 35 Influenza-like symptoms 7 13 Dyspepsia 5 9 Back pain 4 7 Diarrhea 4 7 Pharyngitis 4 7 Rhinitis 3 5 Skeletal pain 3 5 Upper respiratory tract infection 3 5 Table 2: Adverse Reactions that Occurred in ≥ 5% of Type 2 Diabetes Mellitus Adult Patients Treated with NOVOLOG MIX 70/30 NOVOLOG MIX 70/30 (n=85) Preferred Term N % Hypoglycemia 40 47 Upper respiratory tract infection 10 12 Headache 8 9 Diarrhea 7 8 Neuropathy 7 8 Pharyngitis 5 6 Abdominal pain 4 5 Rhinitis 4 5 Severe Hypoglycemia Hypoglycemia is the most commonly observed adverse reaction in patients using insulin, including NOVOLOG MIX 70/30 . The rates of reported hypoglycemia depend on the definition of hypoglycemia used, diabetes type, insulin dose, intensity of glucose control, background therapies, and other intrinsic and extrinsic patient factors. For these reasons, comparing rates of hypoglycemia in clinical trials for NOVOLOG MIX 70/30 with the incidence of hypoglycemia for other products may be misleading and also, may not be representative of hypoglycemia rates that will occur in clinical practice. Severe hypoglycemia requiring the assistance of another person and/or parenteral glucose infusion or glucagon administration has been observed in clinical trials with insulin, including trials with NOVOLOG MIX 70/30. The incidence of severe hypoglycemia in adult patients receiving subcutaneous NOVOLOG MIX 70/30 was 16% and 4% for type 1 and type 2 diabetes patients respectively at 12 weeks [see Clinical Studies (14)] . Allergic Reactions Patients have experienced reactions such as erythema, edema or pruritus at the site of NOVOLOG MIX 70/30 injection. These reactions usually resolve in a few days to a few weeks, but in some occasions, have required discontinuation of NOVOLOG MIX 70/30. Severe cases of generalized allergy (anaphylaxis) have been reported. Adverse Reactions Associated with Insulin Initiation and Glucose Control Intensification Intensification or rapid improvement in glucose control has been associated with transitory, reversible ophthalmologic refraction disorder, worsening of diabetic retinopathy, and acute painful peripheral neuropathy. However, long-term glycemic control decreases the risk of diabetic retinopathy and neuropathy. Lipodystrophy Long-term use of insulin, including NOVOLOG MIX 70/30, can cause lipodystrophy at the site of repeated insulin injections. Lipodystrophy includes lipohypertrophy (thickening of adipose tissue) and lipoatrophy (thinning of adipose tissue), and may affect insulin absorption [see Dosage and Administration (2.1)] . Weight Gain Weight gain can occur with insulins, including NOVOLOG MIX 70/30, and has been attributed to the anabolic effects of insulin and the decrease in glycosuria. Peripheral Edema Insulins, including NOVOLOG MIX 70/30, may cause sodium retention and edema, particularly if previously poor metabolic control is improved by intensified insulin therapy. 6.2 Immunogenicity As with all therapeutic proteins, there is potential for immunogenicity. The detection of antibody formation is highly dependent on the sensitivity and specificity of the assay. Additionally, the observed incidence of antibody (including neutralizing antibody) positivity in an assay may be influenced by several factors including assay methodology, sample handling, timing of sample collection, concomitant medications, and underlying disease. For these reasons, comparison of the incidence of antibodies to NOVOLOG MIX 70/30 in the studies described below with the incidence of antibodies in other studies or to other products may be misleading. In a 3-month study with an extension in adult patients with type 2 diabetes, 100% of patients who received NOVOLOG MIX 70/30 were positive for anti-insulin antibodies (AIA) at least once during the first 12 months of the study including 91.4% that were positive at baseline. A total of 91.4% of patients who received NOVOLOG MIX 70/30 were positive for anti-drug antibodies (ADA) at least once during the first 12 months of the study, including 62.1% that were positive at baseline. In a type 2 diabetes clinical trial of NOVOLOG MIX 70/30, initial increase in titers of antibodies to insulin followed by a decrease approaching to baseline values was observed in NOVOLOG MIX 70/30 and Novolin 70/30 treatment groups with similar incidences. These antibodies did not cause deterioration in glycemic control or necessitate increases in insulin dose. 6.3 Postmarketing Experience The following adverse reactions have been identified during post-approval use of NOVOLOG MIX 70/30. Because these adverse reactions are reported voluntarily from a population of uncertain size, it is generally not possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Medication errors in which other insulins have been accidentally substituted for NOVOLOG MIX 70/30 have been reported. Localized cutaneous amyloidosis at the injection site has occurred with insulin aspart. Hyperglycemia has been reported with repeated insulin injections into areas of localized cutaneous amyloidosis; hypoglycemia has been reported with a sudden change to an unaffected injection site.

4 CONTRAINDICATIONS NOVOLOG MIX 70/30 is contraindicated: • During episodes of hypoglycemia [ see Warnings and Precautions (5.3) ] • In patients with hypersensitivity to NOVOLOG MIX 70/30 or one of its excipients [see Warnings and Precautions (5.5)] • Do not use during episodes of hypoglycemia (4) . • Do not use in patients with hypersensitivity to NOVOLOG MIX 70/30 or one of its excipients (4) .

11 DESCRIPTION Insulin aspart protamine and insulin aspart is a human insulin analog containing 70% insulin aspart protamine crystals and 30% soluble insulin aspart.

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action The primary activity of insulin, including NOVOLOG MIX 70/30 is the regulation of glucose metabolism. Insulin and its analog lower blood glucose by stimulating peripheral glucose uptake, especially by skeletal muscle and fat, and by inhibiting hepatic glucose production. Insulin inhibits lipolysis and proteolysis, and enhances protein synthesis. 12.2 Pharmacodynamics A euglycemic clamp study described below assessed glucose utilization after subcutaneous dosing of NOVOLOG MIX 70/30 in healthy subjects (n = 24). Following a 0.3 units/kg single subcutaneous dose of NOVOLOG MIX 70/30, the onset of action is between 10-20 minutes and the mean ± SD time to peak activity is 2.7 hr ± 0.9 hr. The duration of action may be as long as 24 hours (see Figure 2). Figure 2. Pharmacodynamic Activity Profile of NOVOLOG MIX 70/30 in healthy subjects after a single 0.3 units/kg subcutaneous dose Graph showing glucose infusion rate for NovoLog Mix 0/30 12.3 Pharmacokinetics The single substitution of the amino acid proline with aspartic acid at position B28 in insulin aspart (NOVOLOG) reduces the molecule’s tendency to form hexamers as observed with regular human insulin. The rapid absorption characteristics of NOVOLOG are maintained by NOVOLOG MIX 70/30. Absorption and Bioavailability The 30% insulin aspart in the soluble component of NOVOLOG MIX 70/30 is absorbed rapidly from the subcutaneous layer. The remaining 70% is in crystalline form as insulin aspart protamine which has a prolonged absorption profile after subcutaneous injection. The relative bioavailability of NOVOLOG MIX 70/30 compared to NOVOLOG indicates that the insulins are absorbed to similar extent. In a euglycemic clamp study in healthy subjects (n=24) after dosing with NOVOLOG MIX 70/30 (0.3 units/kg), a mean maximum serum concentration (C max ) of 61.3 ± 20.1 milliunits/L was reached after 85 minutes. Serum insulin levels returned to baseline 16 to 20 hours after a subcutaneous dose of NOVOLOG MIX 70/30 (see Fig. 3 for pharmacokinetic profile). Figure 3. Pharmacokinetic Profile of NOVOLOG MIX 70/30 after a single 0.3 units/kg subcutaneous dose Distribution and Elimination Insulin aspart has a low binding affinity to plasma proteins (<10%), similar to that seen with regular human insulin.

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility Standard 2-year carcinogenicity studies in animals have not been performed to evaluate the carcinogenic potential of NOVOLOG MIX 70/30. In 52-week studies, Sprague-Dawley rats were dosed subcutaneously with NOVOLOG, the rapid-acting component of NOVOLOG MIX 70/30, at 10, 50, and 200 units/kg/day (approximately 2, 8, and 32 times the human subcutaneous dose of 1.0 unit/kg/day, based on units/body surface area, respectively). At a dose of 200 units/kg/day, NOVOLOG increased the incidence of mammary gland tumors in females when compared to untreated controls. The relevance of these findings to humans is not known. NOVOLOG was not genotoxic in the following tests: Ames test, mouse lymphoma cell forward gene mutation test, human peripheral blood lymphocyte chromosome aberration test, in vivo micronucleus test in mice, and in ex viv o UDS test in rat liver hepatocytes. In fertility studies in male and female rats, NOVOLOG at subcutaneous doses up to 200 units/kg/day (approximately 32 times the human subcutaneous dose, based on units/body surface area) had no direct adverse effects on male and female fertility, or on general reproductive performance of animals.

14 CLINICAL STUDIES 14.1 Clinical Studies in Adult Patients with Type 1 and Type 2 Diabetes In a three-month, open-label trial, adult patients with type 1 (n=104) or type 2 (n=187) diabetes mellitus were treated twice daily (before breakfast and before supper) with NOVOLOG MIX 70/30 or Novolin 70/30. Patients had received insulin for at least 24 months before the study. Oral hypoglycemic agents were not allowed within 1 month prior to the study or during the study. The small changes in HbA 1c were comparable across the treatment groups (see Table 4). For patients with type 1 diabetes mellitus (T1DM) the mean age was 43 years old, 64% were male, 100% were White, the mean body mass index (BMI) was 26.1 kg/m 2 , and mean duration of diabetes mellitus was 15 years. For patients with type 2 diabetes mellitus (T2DM), the mean age was 63 years old, 54% were male, 100% were White, the BMI 28.1 kg/m 2 , and the mean duration of diabetes mellitus was 15 years.

The mean age of the trial population was 53 years and mean duration of diabetes was 9.2 years. Forty-six percent were male. Eighty-five percent were White, 12% were Black and 3% were Asian. The mean BMI was approximately 32.4 kg/m 2 . During an 8-week optimization period metformin and pioglitazone were increased to 2,500 mg per day and 30 or 45 mg per day, respectively. After the optimization period, patients were randomized to receive either NOVOLOG MIX 70/30 twice daily added on to the metformin and pioglitazone regimen or continue the current optimized metformin and pioglitazone therapy. NOVOLOG MIX 70/30 was started at a dose of 6 international units twice daily (before breakfast and before supper). Insulin doses were titrated to a pre-meal glucose goal of 80-110 mg/dL. The total daily insulin dose at the end of the study was 56.9 ± 30.5 international units.

Trial 2: In a 28-week, open-label trial (Trial 2), insulin-naïve patients with type 2 diabetes with fasting plasma glucose above 140 mg/dL currently treated with metformin ± thiazolidinedione therapy were randomized to receive either NOVOLOG MIX 70/30 twice daily [before breakfast and before supper] or insulin glargine once daily (see Table 6). NOVOLOG MIX 70/30 was started at an average dose of 5-6 international units (0.07 ± 0.03 international units/kg) twice daily (before breakfast and before supper), and bedtime insulin glargine was started at 10-12 international units (0.13 ± 0.03 international units/kg). Insulin doses were titrated weekly by decrements or increments of -2 to +6 units per injection to a pre-meal glucose goal of 80-110 mg/dL. The metformin dose was adjusted to 2,550 mg/day. Approximately one-third of the patients in each group were also treated with pioglitazone (30 mg/day). Insulin secretagogues were discontinued in order to reduce the risk of hypoglycemia. Most patients were White (53%), and the mean initial weight was 90 kg. The mean age of the trial population was 53 years old and mean duration of diabetes was 9.5 years. Fifty three percent were male. Fifty-five percent were White, 15% Black, 27% were Hispanic, 2% were Asian and 2% were Other. The mean BMI was approximately 31.5 kg/m 2 .

8.5 Geriatric Use Clinical studies of NOVOLOG MIX 70/30 did not include sufficient numbers of patients aged 65 and over to determine whether they respond differently than younger adult patients. In geriatric patients with diabetes, the initial dosing, dose increments should be conservative to avoid hypoglycemic reactions. Hypoglycemia may be difficult to recognize in geriatric patients.

8.4 Pediatric Use Safety and effectiveness of NOVOLOG MIX 70/30 have not been established in pediatric patients with diabetes mellitus.

8.1 Pregnancy Risk Summary There are no available data with NOVOLOG MIX 70/30 in pregnant women to inform a drug-associated risk for major birth defects and miscarriage. Available information from published randomized controlled trials with insulin aspart use during the second trimester of pregnancy have not reported an association with insulin aspart and major birth defects or adverse maternal or fetal 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, administration of subcutaneous insulin aspart to pregnant rats and rabbits during the period of organogenesis did not cause adverse developmental effects at exposures 8-times and equal to the human subcutaneous dose of 1 unit/kg/day, respectively. Pre- and post-implantation losses and visceral/skeletal abnormalities were seen at higher exposures, which are considered secondary to maternal hypoglycemia. These effects were similar to those observed in rats administered regular human insulin [see Data] . The estimated background risk of major birth defects is 6-10% in women with pre-gestational diabetes with a HbA 1c >7% and has been reported to be as high as 20-25% in women with a HbA 1c >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 diabetic ketoacidosis, preeclampsia, spontaneous abortions, preterm delivery, and delivery complications. Poorly controlled diabetes increases the fetal risk for major birth defects, still birth, and macrosomia related morbidity. Data Human Data Published data from 5 randomized controlled trials of 441 pregnant women with diabetes mellitus treated with insulin aspart during the late 2 nd trimester of pregnancy did not identify an association of insulin aspart with major birth defects or adverse maternal or fetal outcomes. However, these studies cannot definitely establish the absence of any risk because of methodological limitations, including a variable duration of treatment and small size of the majority of the trials. Animal Data Fertility, embryo-fetal and pre- and postnatal development studies have been performed with insulin aspart and regular human insulin in rats and rabbits. In a combined fertility and embryo-fetal development study in rats, insulin aspart was administered before mating, during mating, and throughout pregnancy. Further, in a pre- and postnatal development study insulin aspart was given throughout pregnancy and during lactation to rats. In an embryo-fetal development study insulin aspart was given to female rabbits during organogenesis. The effects of insulin aspart did not differ from those observed with subcutaneous regular human insulin. Insulin aspart, like human insulin, caused pre- and post-implantation losses and visceral/skeletal abnormalities in rats at a dose of 200 units/kg/day (approximately 32 times the human subcutaneous dose of 1 unit/kg/day, based on human exposure equivalents) and in rabbits at a dose of 10 units/kg/day (approximately three times the human subcutaneous dose of 1 unit/kg/day, based on human exposure equivalents). No significant effects were observed in rats at a dose of 50 units/kg/day and in rabbits at a dose of 3 units/kg/day. These doses are approximately 8 times the human subcutaneous dose of 1 unit/kg/day for rats and equal to the human subcutaneous dose of 1 unit/kg/day for rabbits, based on human exposure equivalents. The effects are considered secondary to maternal hypoglycemia.

The effects are considered secondary to maternal hypoglycemia. 8.2 Lactation Risk Summary There are no data on the presence of NOVOLOG MIX 70/30 in human milk, the effects on the breastfed infant, or the effect on milk production. One small published study reported that exogenous insulin, including insulin aspart, was present in human milk. However, there is insufficient information to determine the effects of insulin aspart on the breastfed infant. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for NOVOLOG MIX 70/30, and any potential adverse effects on the breastfed infant from NOVOLOG MIX 70/30, or from the underlying maternal condition. 8.4 Pediatric Use Safety and effectiveness of NOVOLOG MIX 70/30 have not been established in pediatric patients with diabetes mellitus. 8.5 Geriatric Use Clinical studies of NOVOLOG MIX 70/30 did not include sufficient numbers of patients aged 65 and over to determine whether they respond differently than younger adult patients. In geriatric patients with diabetes, the initial dosing, dose increments should be conservative to avoid hypoglycemic reactions. Hypoglycemia may be difficult to recognize in geriatric patients. 8.6 Renal Impairment The effect of renal impairment on the pharmacokinetics of NOVOLOG MIX 70/30 has not been studied. Some studies with human insulin have shown increased circulating levels of insulin in patients with renal failure. Patients with renal impairment may be at increased risk of hypoglycemia and may require more frequent NOVOLOG MIX 70/30 dose adjustment and more frequent blood glucose monitoring [see Warnings and Precautions (5.3)] . 8.7 Hepatic Impairment The effect of hepatic impairment on the pharmacokinetics of NOVOLOG MIX 70/30 has not been studied. Patients with hepatic impairment may be at increased risk of hypoglycemia and may require more frequent NOVOLOG MIX 70/30 dose adjustment and more frequent blood glucose monitoring [see Warnings and Precautions (5.3)] .
