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 associated with HUMALOG include hypoglycemia, allergic reactions, injection site reactions, lipodystrophy, pruritus, and rash. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Eli Lilly and Company at 1-800-LillyRx (1-800-545-5979) or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying designs, the adverse reaction rates reported in one clinical trial may not be easily compared with those rates reported in another clinical trial, and may not reflect the rates actually observed in clinical practice. Common adverse reactions, excluding hypoglycemia, were defined as events that occurred in ≥5% of patients treated with insulin lispro or regular human insulin. The frequencies of adverse reactions during HUMALOG clinical trials in patients with type 1 diabetes mellitus and type 2 diabetes mellitus are listed in the tables below. Table 1: Adverse Reactions That Occurred in ≥5% in Patients with Type 1 Diabetes Mellitus HUMALOG (%) (n=81) Regular human insulin (%) (n=86) Flu syndrome 34.6 32.6 Pharyngitis 33.3 33.7 Rhinitis 24.7 29.1 Headache 29.6 22.1 Pain 19.8 16.3 Cough increased 17.3 17.4 Infection 13.6 20.9 Nausea 6.2 15.1 Accidental injury 8.6 11.6 Surgical procedure 6.2 14.0 Fever 6.2 11.6 Abdominal pain 7.4 8.1 Asthenia 7.4 8.1 Bronchitis 7.4 7.0 Diarrhea 8.6 5.8 Dysmenorrhea 6.2 7.0 Myalgia 7.4 5.8 Urinary tract infection 6.2 4.7 Table 2: Adverse Reactions That Occurred in ≥5% in Patients with Type 2 Diabetes Mellitus HUMALOG (%) (n=714) Regular human insulin (%) (n=709) Headache 11.6 9.3 Pain 10.8 10.0 Infection 10.1 7.6 Pharyngitis 6.6 8.2 Rhinitis 8.1 6.6 Flu syndrome 6.2 8.2 Surgical procedure 7.4 6.8 Insulin initiation and intensification of glucose control Intensification or rapid improvement in glucose control has been associated with a 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. Hypoglycemia Hypoglycemia is the most commonly observed adverse reaction in patients using insulin, including HUMALOG. Lipodystrophy Long-term use of insulin, including HUMALOG, can cause lipodystrophy at the site of repeated insulin injections or infusion. Lipodystrophy includes lipohypertrophy (thickening of adipose tissue) and lipoatrophy (thinning of adipose tissue), and may affect insulin absorption [see Dosage and Administration ( 2.2 )] . Weight gain Weight gain can occur with insulins, including HUMALOG, and has been attributed to the anabolic effects of insulin and the decrease in glucosuria. Peripheral Edema Insulins, including HUMALOG, may cause sodium retention and edema, particularly if previously poor metabolic control is improved by intensified insulin therapy. Adverse Reactions with Continuous Subcutaneous Insulin Infusion (CSII) — HUMALOG U-100 In a 12-week, randomized, crossover study in adult patients with type 1 diabetes (n=39), the rates of catheter occlusions and infusion site reactions were similar for HUMALOG U-100 and regular human insulin treated patients ( see Table 3 ). Table 3: Catheter Occlusions and Infusion Site Reactions HUMALOG U-100 (n=38) Regular human insulin (n=39) Catheter occlusions/month 0.09 0.10 Infusion site reactions 2.6% (1/38) 2.6% (1/39) In a randomized, 16-week, open-label, parallel design study of pediatric patients with type 1 diabetes, adverse reactions related to infusion-site reactions were similar for insulin lispro and insulin aspart (21% of 100 patients versus 17% of 198 patients, respectively). In both groups, the most frequently reported infusion site reactions were infusion site erythema and infusion site reaction. Allergic Reactions Local Allergy — As with any insulin, patients taking HUMALOG may experience redness, swelling, or itching at the site of the injection. These minor reactions usually resolve in a few days to a few weeks, but in some occasions, may require discontinuation of HUMALOG. Systemic Allergy — Severe, life-threatening, generalized allergy, including anaphylaxis, may occur with any insulin, including HUMALOG. Generalized allergy to insulin may cause whole body rash (including pruritus), dyspnea, wheezing, hypotension, tachycardia, or diaphoresis. In controlled clinical trials, pruritus (with or without rash) was seen in 17 patients receiving regular human insulin (n=2969) and 30 patients receiving HUMALOG (n=2944). Localized reactions and generalized myalgias have been reported with injected metacresol, which is an excipient in HUMALOG [see Contraindications ( 4 )] . Antibody Production In large clinical trials with patients with type 1 (n=509) and type 2 (n=262) diabetes mellitus, anti-insulin antibody (insulin lispro-specific antibodies, insulin-specific antibodies, cross-reactive antibodies) formation was evaluated in patients receiving both regular human insulin and HUMALOG (including patients previously treated with human insulin and naive patients). As expected, the largest increase in the antibody levels occurred in patients new to insulin therapy. The antibody levels peaked by 12 months and declined over the remaining years of the study. These antibodies do not appear to cause deterioration in glycemic control or necessitate an increase in insulin dose. There was no statistically significant relationship between the change in the total daily insulin dose and the change in percent antibody binding for any of the antibody types. 6.2 Postmarketing Experience The following additional adverse reactions have been identified during post-approval use of HUMALOG. Because these reactions are reported voluntarily from a population of uncertain size, it is not always 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 HUMALOG have been identified during post-approval use. Localized cutaneous amyloidosis at the injection site has occurred. 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 HUMALOG is contraindicated: during episodes of hypoglycemia [see Warnings and Precautions ( 5.3 )] . in patients who are hypersensitive to insulin lispro or to any of the excipients in HUMALOG [see Warnings and Precautions ( 5.5 )] . Do not use during episodes of hypoglycemia. ( 4 ) Do not use in patients with hypersensitivity to insulin lispro or any of the excipients in HUMALOG. ( 4 )

11 DESCRIPTION Insulin lispro is a rapid-acting human insulin analog produced by recombinant DNA technology utilizing a non-pathogenic laboratory strain of Escherichia coli . Insulin lispro differs from human insulin in that the amino acid proline at position B28 is replaced by lysine and the lysine in position B29 is replaced by proline. Chemically, it is Lys(B28), Pro(B29) human insulin analog and has the empirical formula C 257 H 383 N 65 O 77 S 6 and a molecular weight of 5.808 kDa, both identical to that of human insulin. Insulin lispro has the following primary structure: HUMALOG (insulin lispro) injection is a sterile, clear, and colorless solution for subcutaneous or intravenous use. Each mL of HUMALOG U-100 contains 100 units of insulin lispro, and the inactive ingredients: dibasic sodium phosphate (1.0 mg), glycerin (16 mg), metacresol (3.15 mg), trace amounts of phenol, zinc oxide (content adjusted to provide 0.0197 mg zinc ion), and Water for Injection, USP. Each mL of HUMALOG U-200 contains 200 units of insulin lispro, and the inactive ingredients: glycerin (16 mg), metacresol (3.15 mg), trace amounts of phenol, tromethamine (5 mg), zinc oxide (content adjusted to provide 0.046 mg zinc ion), and Water for Injection, USP. HUMALOG has a pH of 7.0 to 7.8. Hydrochloric acid 10% and/or sodium hydroxide 10% is added to adjust the pH. Primary Structure

1 INDICATIONS AND USAGE HUMALOG is indicated to improve glycemic control in adult and pediatric patients with diabetes mellitus. HUMALOG is a rapid acting human insulin analog indicated to improve glycemic control in adult and pediatric patients with diabetes mellitus. ( 1 )

10 OVERDOSAGE Excess insulin administration may cause hypoglycemia and hypokalemia. Mild episodes of hypoglycemia usually can be treated with oral glucose. Adjustments in drug dosage, meal patterns, or exercise may be needed. More severe episodes with coma, seizure, or neurologic impairment may be treated with a glucagon product for emergency use or concentrated intravenous glucose. Sustained carbohydrate intake and observation may be necessary because hypoglycemia may recur after apparent clinical recovery. Hypokalemia must be corrected appropriately.

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Regulation of glucose metabolism is the primary activity of insulins and insulin analogs, including insulin lispro. Insulins lower blood glucose by stimulating peripheral glucose uptake by skeletal muscle and fat, and by inhibiting hepatic glucose production. Insulins inhibit lipolysis and proteolysis, and enhance protein synthesis. 12.2 Pharmacodynamics HUMALOG has been shown to be equipotent to human insulin on a molar basis. One unit of HUMALOG has the same glucose-lowering effect as one unit of regular human insulin. Studies in normal volunteers and patients with diabetes demonstrated that HUMALOG has a more rapid onset of action and a shorter duration of activity than regular human insulin when given subcutaneously. The time course of action of insulin and insulin analogs, such as HUMALOG, may vary considerably in different individuals or within the same individual. The parameters of HUMALOG activity (time of onset, peak time, and duration) as designated in Figure 1 should be considered only as general guidelines. The rate of insulin absorption, and consequently the onset of activity are known to be affected by the site of injection, exercise, and other variables [see Warnings and Precautions ( 5.2 )] . Figure 1: Blood Glucose Levels After Subcutaneous Injection of Regular Human Insulin or HUMALOG (0.2 unit/kg) Immediately Before a High Carbohydrate Meal in 10 Patients with Type 1 Diabetes a . a Baseline insulin concentration was maintained by infusion of 0.2 mU/min/kg human insulin. Figure Intravenous Administration of HUMALOG U-100 — The glucose lowering effect of intravenously administered HUMALOG was tested in 21 patients with type 1 diabetes. For the study, the patients' usual doses of insulin were held and blood glucose concentrations were allowed to reach a stable range of 200 to 260 mg/dL during a one to three hours run-in phase. The run-in phase was followed by a 6-hour assessment phase. During the assessment phase, patients received intravenous HUMALOG at an initial infusion rate of 0.5 units/hour. The infusion rate of HUMALOG could be adjusted at regular timed intervals to achieve and maintain blood glucose concentrations between 100 to 160 mg/dL. The mean blood glucose levels during the assessment phase for patients on HUMALOG therapy are summarized below in Table 4 . All patients achieved the targeted glucose range at some point during the 6-hour assessment phase. At the endpoint, blood glucose was within the target range (100 to 160 mg/dL) for 17 of 20 patients treated with HUMALOG. The average time (±SE) required to attain near normoglycemia was 129 ± 14 minutes for HUMALOG. Table 4: Mean Blood Glucose Concentrations (mg/dL) During Intravenous Infusions of HUMALOG U-100 a Results shown as mean ± SD Time from Start of Infusion (minutes) Mean Blood Glucose (mg/dL) Intravenous a 0 224 ± 16 30 205 ± 21 60 195 ± 20 120 165 ± 26 180 140 ± 26 240 123 ± 20 300 120 ± 27 360 122 ± 25 The pharmacodynamics of a single 20 unit dose of HUMALOG U-200 administered subcutaneously were compared to the pharmacodynamics of a single 20 unit dose of HUMALOG U-100 administered subcutaneously in a euglycemic clamp study enrolling healthy subjects. In this study, the overall, maximum, and time to maximum glucose lowering effect were similar between HUMALOG U-200 and HUMALOG U-100. The mean area under the glucose infusion rate curves (measure of overall pharmacodynamic effect) were 125 g and 126 g for HUMALOG U-200 and HUMALOG U-100, respectively. The maximum glucose infusion rate was 534 mg/min and 559 mg/min and the corresponding median time (min, max) to maximum effect were 2.8 h (0.5 h – 6.3 h) and 2.4 h (0.5 h – 4.7 h) for HUMALOG U-200 and HUMALOG U-100, respectively. 12.3 Pharmacokinetics Absorption and Bioavailability — Studies in healthy volunteers and patients with diabetes demonstrated that HUMALOG is absorbed more quickly than regular human insulin. In healthy volunteers given subcutaneous doses of HUMALOG ranging from 0.1 to 0.4 unit/kg, peak serum levels were seen 30 to 90 minutes after dosing. When healthy volunteers received equivalent doses of regular human insulin, peak insulin levels occurred between 50 to 120 minutes after dosing. Similar results were seen in patients with type 1 diabetes ( see Figure 2 ). Figure 2: Serum HUMALOG and Insulin Levels After Subcutaneous Injection of Regular Human Insulin or HUMALOG (0.2 unit/kg) Immediately Before a High Carbohydrate Meal in 10 Patients with Type 1 Diabetes a . a Baseline insulin concentration was maintained by infusion of 0.2 mU/min/kg human insulin. HUMALOG U-100 was absorbed at a consistently faster rate than regular human insulin in healthy male volunteers given 0.2 unit/kg at abdominal, deltoid, or femoral subcutaneous sites. After HUMALOG was administered in the abdomen, serum drug levels were higher and the duration of action was slightly shorter than after deltoid or thigh administration. Bioavailability of HUMALOG is similar to that of regular human insulin. The absolute bioavailability after subcutaneous injection ranges from 55% to 77% with doses between 0.1 to 0.2 unit/kg, inclusive. The results of a study in healthy subjects demonstrated that HUMALOG U-200 is bioequivalent to HUMALOG U-100 following administration of a single 20 unit dose. The mean observed area under the serum insulin concentration-time curve from time zero to infinity was 2360 pmol hr/L and 2390 pmol hr/L for HUMALOG U-200 and HUMALOG U-100, respectively. The corresponding mean peak serum insulin concentration was 795 pmol/L and 909 pmol/L for HUMALOG U-200 and HUMALOG U-100, respectively. The median time to maximum concentration was 1.0 hour for both formulations. Figure Distribution — When administered intravenously as bolus injections of 0.1 and 0.2 U/kg dose in two separate groups of healthy subjects, the mean volume of distribution of HUMALOG appeared to decrease with increase in dose (1.55 and 0.72 L/kg, respectively) in contrast to that of regular human insulin for which, the volume of distribution was comparable across the two dose groups (1.37 and 1.12 L/kg for 0.1 and 0.2 U/kg dose, respectively). Metabolism — Human metabolism studies have not been conducted. However, animal studies indicate that the metabolism of HUMALOG is identical to that of regular human insulin. Elimination — After subcutaneous administration of HUMALOG, the t 1/2 is shorter than that of regular human insulin (1 versus 1.5 hours, respectively). When administered intravenously, HUMALOG and regular human insulin demonstrated similar dose-dependent clearance, with a mean clearance of 21.0 mL/min/kg and 21.4 mL/min/kg, respectively (0.1 unit/kg dose), and 9.6 mL/min/kg and 9.4 mL/min/kg, respectively (0.2 unit/kg dose). Accordingly, HUMALOG demonstrated a mean t 1/2 of 0.85 hours (51 minutes) and 0.92 hours (55 minutes), respectively for 0.1 unit/kg and 0.2 unit/kg doses, and regular human insulin mean t 1/2 was 0.79 hours (47 minutes) and 1.28 hours (77 minutes), respectively for 0.1 unit/kg and 0.2 unit/kg doses. Specific Populations The effects of age, gender, race, obesity, pregnancy, or smoking on the pharmacokinetics of HUMALOG have not been studied. Renal Impairment — Type 2 diabetic patients with varying degree of renal impairment showed no difference in pharmacokinetics of regular insulin and HUMALOG. However, the sensitivity of the patients to insulin did change, with an increased response to insulin as the renal function declined. Some studies with human insulin have shown increased circulating levels of insulin in patients with renal impairment [see Use in Specific Populations ( 8.6 )]. Hepatic Impairment — Type 2 diabetic patients with impaired hepatic function showed no effect on the pharmacokinetics of HUMALOG as compared to patients with no hepatic dysfunction. However, some studies with human insulin have shown increased circulating levels of insulin in patients with liver failure [see Use in Specific Populations ( 8.7 )].

HUMALOG U-100 was absorbed at a consistently faster rate than regular human insulin in healthy male volunteers given 0.2 unit/kg at abdominal, deltoid, or femoral subcutaneous sites. After HUMALOG was administered in the abdomen, serum drug levels were higher and the duration of action was slightly shorter than after deltoid or thigh administration. Bioavailability of HUMALOG is similar to that of regular human insulin. The absolute bioavailability after subcutaneous injection ranges from 55% to 77% with doses between 0.1 to 0.2 unit/kg, inclusive. The results of a study in healthy subjects demonstrated that HUMALOG U-200 is bioequivalent to HUMALOG U-100 following administration of a single 20 unit dose. The mean observed area under the serum insulin concentration-time curve from time zero to infinity was 2360 pmol hr/L and 2390 pmol hr/L for HUMALOG U-200 and HUMALOG U-100, respectively. The corresponding mean peak serum insulin concentration was 795 pmol/L and 909 pmol/L for HUMALOG U-200 and HUMALOG U-100, respectively. The median time to maximum concentration was 1.0 hour for both formulations. Figure Distribution — When administered intravenously as bolus injections of 0.1 and 0.2 U/kg dose in two separate groups of healthy subjects, the mean volume of distribution of HUMALOG appeared to decrease with increase in dose (1.55 and 0.72 L/kg, respectively) in contrast to that of regular human insulin for which, the volume of distribution was comparable across the two dose groups (1.37 and 1.12 L/kg for 0.1 and 0.2 U/kg dose, respectively). Metabolism — Human metabolism studies have not been conducted. However, animal studies indicate that the metabolism of HUMALOG is identical to that of regular human insulin. Elimination — After subcutaneous administration of HUMALOG, the t 1/2 is shorter than that of regular human insulin (1 versus 1.5 hours, respectively). When administered intravenously, HUMALOG and regular human insulin demonstrated similar dose-dependent clearance, with a mean clearance of 21.0 mL/min/kg and 21.4 mL/min/kg, respectively (0.1 unit/kg dose), and 9.6 mL/min/kg and 9.4 mL/min/kg, respectively (0.2 unit/kg dose). Accordingly, HUMALOG demonstrated a mean t 1/2 of 0.85 hours (51 minutes) and 0.92 hours (55 minutes), respectively for 0.1 unit/kg and 0.2 unit/kg doses, and regular human insulin mean t 1/2 was 0.79 hours (47 minutes) and 1.28 hours (77 minutes), respectively for 0.1 unit/kg and 0.2 unit/kg doses. Specific Populations The effects of age, gender, race, obesity, pregnancy, or smoking on the pharmacokinetics of HUMALOG have not been studied. Renal Impairment — Type 2 diabetic patients with varying degree of renal impairment showed no difference in pharmacokinetics of regular insulin and HUMALOG. However, the sensitivity of the patients to insulin did change, with an increased response to insulin as the renal function declined. Some studies with human insulin have shown increased circulating levels of insulin in patients with renal impairment [see Use in Specific Populations ( 8.6 )]. Hepatic Impairment — Type 2 diabetic patients with impaired hepatic function showed no effect on the pharmacokinetics of HUMALOG as compared to patients with no hepatic dysfunction. However, some studies with human insulin have shown increased circulating levels of insulin in patients with liver failure [see Use in Specific Populations ( 8.7 )].

13.2 Animal Toxicology and/or Pharmacology In standard biological assays in fasted rabbits, 0.2 unit/kg of insulin lispro injected subcutaneously had the same glucose-lowering effect and had a more rapid onset of action as 0.2 unit/kg of regular human insulin.

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility Standard 2-year carcinogenicity studies in animals have not been performed. In Fischer 344 rats, a 12-month repeat-dose toxicity study was conducted with insulin lispro at subcutaneous doses of 20 and 200 units/kg/day (approximately 3 and 32 times the human subcutaneous dose of 1 unit/kg/day, based on units/body surface area). Insulin lispro did not produce important target organ toxicity including mammary tumors at any dose. Insulin lispro was not mutagenic in the following genetic toxicity assays: bacterial mutation, unscheduled DNA synthesis, mouse lymphoma, chromosomal aberration and micronucleus assays. Male fertility was not compromised when male rats given subcutaneous insulin lispro injections of 5 and 20 units/kg/day (0.8 and 3 times the human subcutaneous dose of 1 unit/kg/day, based on units/body surface area) for 6 months were mated with untreated female rats. In a combined fertility, perinatal, and postnatal study in male and female rats given 1, 5, and 20 units/kg/day subcutaneously (0.2, 0.8, and 3 times the human subcutaneous dose of 1 unit/kg/day, based on units/body surface area), mating and fertility were not adversely affected in either gender at any dose.

17 PATIENT COUNSELING INFORMATION Advise the patient to read the FDA-approved patient labeling (Patient Information and Instructions for Use). Never Share a HUMALOG Prefilled Pen, Cartridge, Reusable Pen Compatible with Lilly 3 mL Cartridges, or Syringe Between Patients Advise patients that they must never share a HUMALOG prefilled pen, cartridge, or reusable pen compatible with Lilly 3 mL cartridges with another person, even if the needle is changed. Advise patients using HUMALOG vials not to share needles or syringes with another person. Sharing poses a risk for transmission of blood-borne pathogens [see Warnings and Precautions ( 5.1 )] . Hyperglycemia or Hypoglycemia Instruct patients on self-management procedures including glucose monitoring, proper injection technique, and management of hypoglycemia and hyperglycemia, especially at initiation of HUMALOG 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 ( 5.3 )] . Advise patients that changes in insulin regimen can predispose to hyperglycemia or hypoglycemia and that changes in insulin regimen should be made under close medical supervision [see Warnings and Precautions ( 5.2 )] . Hypoglycemia due to Medication Errors Instruct patients to always check the insulin container label before each injection to avoid mix-ups between insulin products [see Warnings and Precautions ( 5.4 )] . Inform patients that HUMALOG U-200 contains 2 times as much insulin per mL as HUMALOG U-100. The HUMALOG U-200 KwikPen dose window shows the number of units of HUMALOG U-200 to be injected so no dose conversion is required [see Dosage and Administration ( 2.1 )]. Instruct patients to NOT transfer HUMALOG U-200 from the HUMALOG U-200 KwikPen to a syringe. The markings on the syringe will not measure the dose correctly and this can result in overdosage and severe hypoglycemia. [see Warnings and Precautions ( 5.4 )]. Hypersensitivity Reactions Advise patients that hypersensitivity reactions have occurred with HUMALOG. Inform patients on the symptoms of hypersensitivity reactions [see Warnings and Precautions ( 5.5 )] . Administration Instruction for HUMALOG U-200 Instruct patients to NOT mix HUMALOG U-200 with any other insulin. Instructions For Patients Using Continuous Subcutaneous Insulin Pumps Do not use HUMALOG U-200 in a subcutaneous insulin pump. Train patients in intensive insulin therapy with multiple injections and in the function of their pump and pump accessories. Instruct patients to follow healthcare provider recommendations when setting pump basal rates and bolus settings. Refer to the continuous subcutaneous infusion pump user manual to see if HUMALOG can be used with the pump. See recommended reservoir and infusion sets in the insulin pump user manual. Instruct patients to replace insulin in the reservoir at least every 7 days, or according to the pump user manual, whichever is shorter; infusion sets and infusion set insertion sites should be changed in accordance with the manufacturers' user manual. By following this schedule, patients avoid insulin degradation, infusion set occlusion, and loss of the insulin preservative. Instruct patients to discard insulin exposed to temperatures higher than 98.6°F (37°C). The temperature of the insulin may exceed ambient temperature when the pump housing, cover, tubing or sport case is exposed to sunlight or radiant heat. Instruct patients to inform healthcare provider and select a new site for infusion if infusion site becomes erythematous, pruritic, or thickened. Instruct patients on the risk of rapid hyperglycemia and ketosis due to pump malfunction, infusion set occlusion, leakage, disconnection or kinking, and degraded insulin. Instruct patients on the risk of hypoglycemia from pump malfunction. If these problems cannot be promptly corrected, instruct patients to resume therapy with subcutaneous insulin injection and contact their healthcare provider [see Warnings and Precautions ( 5 ) and How Supplied/Storage and Handling ( 16.2 )] .

U-100 Vial Instructions for Use INSTRUCTIONS FOR USE HUMALOG ® (HU-ma-log) (insulin lispro) injection, for subcutaneous use 3 mL or 10 mL multiple-dose vial (100 units per mL, U-100) Read this Instructions for Use before you start taking HUMALOG and each time you get a new vial. There may be new information. This information does not take the place of talking to your healthcare provider about your medical condition or your treatment. Do not share your needles or syringes with other people, even if the needle has been changed. You may give other people a serious infection or get a serious infection from them. Supplies needed to give your injection a multiple-dose HUMALOG vial a U-100 insulin syringe and needle 2 alcohol swabs gauze 1 sharps container for throwing away used needles and syringes. See “ Disposing of used needles and syringes ” at the end of these instructions. Vial Syringe Preparing your HUMALOG dose Wash your hands with soap and water. Check the HUMALOG label to make sure you are taking the right type of insulin. This is especially important if you use more than 1 type of insulin. HUMALOG should look clear and colorless. Do not use HUMALOG if it is thick, cloudy, or colored, or if you see lumps or particles in it. Do not use HUMALOG past the expiration date printed on the label or 28 days after you first use it. Always use a new syringe and needle for each injection to prevent infections and blocked needles. Do not reuse or share your syringes or needles with other people. You may give other people a serious infection or get a serious infection from them. Step 1: If you are using a new vial, pull off the plastic Protective Cap, but do not remove the Rubber Stopper. Step 2: Wipe the Rubber Stopper with an alcohol swab. Step 3: Remove the Needle Shield from the syringe by pulling the Needle Shield straight off. Hold the syringe with the needle pointing up. Pull down on the Plunger until the Plunger Tip reaches the line for the number of units for your prescribed dose. (Example Dose: 20 units shown) Step 4: Push the needle through the Rubber Stopper of the vial. Step 5: Push the Plunger all the way in. This puts air into the vial. Step 6: Turn the vial and syringe upside down and slowly pull the Plunger down until the Plunger Tip is a few units past the line for your prescribed dose. (Example Dose: 20 units Plunger is shown at 24 units) If there are air bubbles, tap the syringe gently a few times to let any air bubbles rise to the top. Step 7: Slowly push the Plunger up until the Plunger Tip reaches the line for your prescribed dose. Check the syringe to make sure that you have the right dose. (Example Dose: 20 units shown) Step 8: Pull the syringe out of the Rubber Stopper of the vial. If you use HUMALOG with NPH insulin: NPH insulin is the only type of insulin that can be mixed with HUMALOG. Do not mix HUMALOG with any other type of insulin. HUMALOG should be drawn up into the syringe first, before you draw up your NPH insulin. Talk to your healthcare provider if you are not sure about the right way to mix HUMALOG and NPH insulin. Give your injection right away. Giving your HUMALOG injection with a syringe Inject your insulin exactly as your healthcare provider has shown you. Your healthcare provider should tell you if you should pinch the skin before injecting. HUMALOG starts acting fast, so give your injection within 15 minutes before or right after you eat a meal. Change (rotate) your injection sites within the area you choose for each dose to reduce your risk of getting lipodystrophy (pits in skin or thickened skin) and localized cutaneous amyloidosis (skin with lumps) at the injection sites. Do not inject where the skin has pits, is thickened, or has lumps. Do not inject where the skin is tender, bruised, scaly or hard, or into scars or damaged skin. Step 9: Choose your injection site. HUMALOG is injected under the skin (subcutaneously) of your stomach area (abdomen), buttocks, upper legs or upper arms. Wipe the skin with an alcohol swab. Let the injection site dry before you inject your dose. Step 10: Insert the needle into your skin. Step 11: Push down on the Plunger to inject your dose. The needle should stay in your skin for at least 5 seconds to make sure you have injected all of your insulin dose. Step 12: Pull the needle out of your skin. If you see blood after you take the needle out of your skin, press the injection site with a piece of gauze or an alcohol swab. Do not rub the area. Do not recap the needle. Recapping the needle can lead to a needle stick injury. Giving your HUMALOG using an insulin pump HUMALOG should be given into an area of your body recommended in the instructions that come with your insulin pump. Change your infusion set and rotate the infusion set insertion site according to the manufacturer's user manual. Change (rotate) your insertion sites within the area you choose for each insertion to reduce your risk of getting lipodystrophy (pits in skin or thickened skin) and localized cutaneous amyloidosis (skin with lumps) at the insertion sites. Do not insert into the exact same spot for each insertion. Do not insert where the skin has pits, is thickened, or has lumps. Do not insert where the skin is tender, bruised, scaly or hard, or into scars or damaged skin. Change the insulin in the reservoir at least every 7 days or according to the pump user manual, whichever is shorter, even if you have not used all of the insulin. Do not dilute or mix HUMALOG with any other type of insulin in your insulin pump. See your insulin pump manual for instructions or talk to your healthcare provider. Disposing of used needles and syringes Put your used needles and syringes in a FDA-cleared sharps disposal container right away after use. Do not throw away (dispose of) loose needles and syringes in your household trash. If you do not have a FDA-cleared sharps disposal container, you may use a household container that is: - made of a heavy-duty plastic, - can be closed with a tight-fitting, puncture-resistant lid, without sharps being able to come out, - upright and stable during use, - leak-resistant, and - properly labeled to warn of hazardous waste inside the container. When your sharps disposal container is almost full, you will need to follow your community guidelines for the right way to dispose of your sharps disposal container. There may be state or local laws about how you should throw away used needles and syringes. For more information about safe sharps disposal, and for specific information about sharps disposal in the state that you live in, go to the FDA's website at: http://www.fda.gov/safesharpsdisposal. Do not dispose of your used sharps disposal container in your household trash unless your community guidelines permit this. Do not recycle your used sharps disposal container. How should I store HUMALOG? All unopened vials: Store all unopened vials in the refrigerator at 36°F to 46°F (2°C to 8°C). Do not freeze. Do not use if HUMALOG has been frozen. Keep away from heat and out of direct light. Unopened vials can be used until the expiration date on the carton and label, if they have been stored in the refrigerator. Unopened vials should be thrown away after 28 days, if they are stored at room temperature. After vials have been opened: Store opened vials in the refrigerator or at room temperature up to 86°F (30°C) for up to 28 days. Keep vials away from heat and out of direct light. Throw away all opened vials after 28 days of use, even if there is insulin left in the vial. HUMALOG in an insulin pump: Throw away HUMALOG in the pump reservoir if it has been exposed to temperatures higher than 98.6°F (37°C). Keep HUMALOG vials, syringes, needles and all medicines out of the reach of children.

14 CLINICAL STUDIES The safety and efficacy of HUMALOG U-100 were studied in pediatric and adult patients with type 1 diabetes (n=789) and adult patients with type 2 diabetes (n=722). 14.1 Type 1 Diabetes – Adults and Pediatric Patients Aged 12 years and Older A 12-month, randomized, parallel, open-label, active-controlled study was conducted in patients with type 1 diabetes to assess the safety and efficacy of HUMALOG (n=81) compared with Humulin ® R [insulin human injection (100 units/mL)] (n=86). HUMALOG was administered by subcutaneous injection immediately prior to meals and Humulin R was administered 30 to 45 minutes before meals. Humulin ® U [ULTRALENTE ® human insulin (rDNA origin) extended zinc suspension] was administered once or twice daily as the basal insulin. There was a 2- to 4-week run-in period with Humulin R and Humulin U before randomization. Most patients were Caucasian (97%). Forty-seven percent of the patients were male. The mean age was 31 years (range 12 to 70 years). Glycemic control, the total daily doses of HUMALOG and Humulin R, and the incidence of severe hypoglycemia (as determined by the number of events that were not self-treated) were similar in the two treatment groups. There were no episodes of diabetic ketoacidosis in either treatment group. Table 5: Type 1 Diabetes Mellitus – Adults and Pediatric Patients Aged 12 years and Older a Values are Mean ± SD b Severe hypoglycemia refers to hypoglycemia for which patients were not able to self-treat.

HUMALOG achieved glycemic control comparable to Humulin R, as measured by HbA 1c ( see Table 6 ), and both treatment groups had a comparable incidence of hypoglycemia. In a 9-month, crossover study of pediatric patients (n=60) with type 1 diabetes, aged 3 to 11 years, HUMALOG administered immediately before meals, HUMALOG administered immediately after meals and Humulin R administered 30 minutes before meals resulted in similar glycemic control, as measured by HbA 1c , and incidence of hypoglycemia, regardless of treatment group. Table 6: Pediatric Subcutaneous Administration of HUMALOG in Type 1 Diabetes a Values are Mean ± SD b Severe hypoglycemia refers to hypoglycemia that required glucagon or glucose injection or resulted in coma.

One study involved 39 patients, ages 19 to 58 years, treated for 24 weeks with HUMALOG or regular human insulin. After 12 weeks of treatment, the mean HbA 1c values decreased from 7.8% to 7.2% in the HUMALOG-treated patients and from 7.8% to 7.5% in the regular human insulin-treated patients. Another study involved 60 patients (mean age 39, range 15 to 58 years) treated for 24 weeks with either HUMALOG or buffered regular human insulin. After 12 weeks of treatment, the mean HbA 1c values decreased from 7.7% to 7.4% in the HUMALOG-treated patients and remained unchanged from 7.7% in the buffered regular human insulin-treated patients. Rates of hypoglycemia were comparable between treatment groups in both studies. 14.4 Type 1 Diabetes – Pediatric Continuous Subcutaneous Insulin Infusion A randomized, 16-week, open-label, parallel design, study of pediatric patients with type 1 diabetes (n=298) aged 4 to 18 years compared two subcutaneous infusion regimens administered via an external insulin pump: insulin aspart (n=198) or HUMALOG U-100 (n=100). These two treatments resulted in comparable changes from baseline in HbA 1c and comparable rates of hypoglycemia after 16 weeks of treatment ( see Table 7 ). Infusion site reactions were similar between groups. Table 7: Pediatric Insulin Pump Study in Type 1 Diabetes (16 weeks; n=298) a Values are Mean ± SD b Severe hypoglycemia refers to hypoglycemia associated with central nervous system symptoms and requiring the intervention of another person or hospitalization.

HUMALOG was administered by subcutaneous injection immediately before meals and Humulin R was administered 30 to 45 minutes before meals. Humulin ® N [NPH human insulin (rDNA origin) isophane suspension] or Humulin U was administered once or twice daily as the basal insulin. All patients participated in a 2- to 4-week run-in period with Humulin R and Humulin N or Humulin U. Most of the patients were Caucasian (88%), and the numbers of men and women in each group were approximately equal. The mean age was 58.6 years (range 23.8 to 85 years). The average body mass index (BMI) was 28.2 kg/m 2 . During the study, the majority of patients used Humulin N (84%) compared with Humulin U (16%) as their basal insulin. The reductions from baseline in HbA 1c and the incidence of severe hypoglycemia (as determined by the number of events that were not self-treated) were similar between the two treatments from the combined groups ( see Table 8 ). Table 8: Type 2 Diabetes Mellitus — Adults a Values are Mean ± SD b Severe hypoglycemia refers to hypoglycemia for which patients were not able to self-treat. End point Baseline HUMALOG + Basal Humulin R + Basal HbA 1c (%) a 8.9 ± 1.7 8.2 ± 1.3 8.2 ± 1.4 Change from baseline HbA 1c (%) a — -0.7 ± 1.4 -0.7 ± 1.3 Short-acting insulin dose (units/kg/day) a 0.3 ± 0.2 0.3 ± 0.2 0.3 ± 0.2 Change from baseline short-acting insulin dose (units/kg/day) a — 0.0 ± 0.1 0.0 ± 0.1 Body weight (kg) a 80 ± 15 81 ± 15 81 ± 15 Weight change from baseline — 0.8 ± 2.7 0.9 ± 2.6 Patients with severe hypoglycemia (n, %) b — 15 (2%) 16 (2%)

8.5 Geriatric Use Of the total number of patients (n=2,834) in eight clinical studies of HUMALOG, twelve percent (n=338) were 65 years of age or over. The majority of these patients had type 2 diabetes. HbA 1c values and hypoglycemia rates did not differ by age. Pharmacokinetic/pharmacodynamic studies to assess the effect of age on the onset of HUMALOG action have not been performed.

8.4 Pediatric Use The safety and effectiveness of HUMALOG to improve glycemic control have been established in pediatric patients with diabetes mellitus. Use of HUMALOG for this indication is supported by evidence from adequate and well-controlled studies in 831 pediatric patients with type 1 diabetes mellitus aged 3 years and older and from studies in adults with diabetes mellitus [see Adverse Reactions ( 6.1 ), Clinical Pharmacology ( 12.3 ), and Clinical Studies ( 14 )].

8.1 Pregnancy Risk Summary Published studies with insulin lispro used during pregnancy have not reported an association between insulin lispro and the induction of major birth defects, miscarriage, 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) . Pregnant rats and rabbits were exposed to insulin lispro in animal reproduction studies during organogenesis. No adverse effects on embryo/fetal viability or morphology were observed in offspring of rats exposed to insulin lispro at a dose approximately 3 times the human subcutaneous dose of 1 unit insulin lispro/kg/day. No adverse effects on embryo/fetal development were observed in offspring of rabbits exposed to insulin lispro at doses up to approximately 0.2 times the human subcutaneous dose of 1 unit/kg/day (see Data) . The estimated background risk of major birth defects is 6-10% in women with pre-gestational diabetes with a HbA1c >7 and has been reported to be as high as 20-25% in women with a 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 diabetic ketoacidosis, pre-eclampsia, spontaneous abortions, preterm delivery, and delivery complications. Poorly controlled diabetes increases the fetal risk for major birth defects, stillbirth, and macrosomia related morbidity. Data Human Data Published data from retrospective studies and meta-analyses do not report an association with insulin lispro and major birth defects, miscarriage, or adverse maternal or fetal outcomes when insulin lispro is used during pregnancy. However, these studies cannot definitely establish or exclude the absence of any risk because of methodological limitations including small sample size, selection bias, confounding by unmeasured factors, and some lacking comparator groups. Animal Data In a combined fertility and embryo-fetal development study, female rats were given subcutaneous insulin lispro injections of 1, 5, and 20 units/kg/day (0.2, 0.8, and 3 times the human subcutaneous dose of 1 unit insulin lispro/kg/day, based on units/body surface area, respectively) from 2 weeks prior to cohabitation through Gestation Day 19. There were no adverse effects on female fertility, implantation, or fetal viability and morphology. However, fetal growth retardation was produced at the 20 units/kg/day-dose as indicated by decreased fetal weight and an increased incidence of fetal runts/litter. In an embryo-fetal development study in pregnant rabbits, insulin lispro doses of 0.1, 0.25, and 0.75 unit/kg/day (0.03, 0.08, and 0.2 times the human subcutaneous dose of 1 unit insulin lispro/kg/day, based on units/body surface area, respectively) were injected subcutaneously on Gestation days 7 through 19. There were no adverse effects on fetal viability, weight, and morphology at any dose.

There were no adverse effects on fetal viability, weight, and morphology at any dose. 8.2 Lactation Risk Summary Available data from published literature suggests that exogenous human insulin products, including insulin lispro, are transferred into human milk. There are no adverse reactions reported in breastfed infants in the literature. There are no data on the effects of exogenous human insulin products, including insulin lispro, on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for insulin, any potential adverse effects on the breastfed child from HUMALOG or from the underlying maternal condition. 8.4 Pediatric Use The safety and effectiveness of HUMALOG to improve glycemic control have been established in pediatric patients with diabetes mellitus. Use of HUMALOG for this indication is supported by evidence from adequate and well-controlled studies in 831 pediatric patients with type 1 diabetes mellitus aged 3 years and older and from studies in adults with diabetes mellitus [see Adverse Reactions ( 6.1 ), Clinical Pharmacology ( 12.3 ), and Clinical Studies ( 14 )]. 8.5 Geriatric Use Of the total number of patients (n=2,834) in eight clinical studies of HUMALOG, twelve percent (n=338) were 65 years of age or over. The majority of these patients had type 2 diabetes. HbA 1c values and hypoglycemia rates did not differ by age. Pharmacokinetic/pharmacodynamic studies to assess the effect of age on the onset of HUMALOG action have not been performed. 8.6 Renal Impairment Patients with renal impairment may be at increased risk of hypoglycemia and may require more frequent HUMALOG dose adjustment and more frequent blood glucose monitoring [see Clinical Pharmacology ( 12.3 )] . 8.7 Hepatic Impairment Patients with hepatic impairment may be at increased risk of hypoglycemia and may require more frequent HUMALOG dose adjustment and more frequent blood glucose monitoring [see Clinical Pharmacology ( 12.3 )] .
