CLINICAL PHARMACOLOGY 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. 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]. 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 Diabetesa. a Baseline insulin concentration was maintained by infusion of 0.2 mU/min/kg human insulin. 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 Time from Start of Infusion (minutes) Mean Blood Glucose (mg/dL) Intravenousa 0 224 ± 16 30 205 ± 21 60 195 ± 20 120 165 ± 26 180 140 ± 26 240 123 ± 20 300 120 ± 27 360 122 ± 25 a Results shown as mean ± SD 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. 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 Diabetesa. 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. 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 t1/2 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 t1/2 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 t1/2 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. Careful glucose monitoring and dose adjustments of insulin, including HUMALOG, may be necessary in patients with renal dysfunction. 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. Careful glucose monitoring and dose adjustments of insulin, including HUMALOG, may be necessary in patients with hepatic dysfunction. 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. Clinical Studies The safety and efficacy of HUMALOG U-100 were studied in children, adolescent, and adult patients with type 1 diabetes (n=789) and adult patients with type 2 diabetes (n=722). Type 1 Diabetes – Adults And Adolescents 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 [REGULAR insulin human injection, USP (rDNA origin)] (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.

Type 2 Diabetes – Adults A 6-month randomized, crossover, open-label, active-controlled study was conducted in insulin-treated patients with type 2 diabetes (n=722) to assess the safety and efficacy of HUMALOG for 3 months followed by Humulin R for 3 months or the reverse sequence. 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 4week 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/m2. 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 HbA1c 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 6). Table 6: Type 2 Diabetes Mellitus — Adults End point Baseline HUMALOG + Basal Humulin R + Basal HbA1c (%)a 8.9 ± 1.7 8.2 ± 1.3 8.2 ± 1.4 Change from baseline HbA1c (%)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%) a Values are Mean ± SD b Severe hypoglycemia refers to hypoglycemia for which patients were not able to self-treat. Type 1 Diabetes – Pediatric And Adolescents An 8-month, crossover study of adolescents with type 1 diabetes (n=463), aged 9 to 19 years, compared two subcutaneous multiple-dose treatment regimens: HUMALOG or Humulin R, both administered with Humulin N (NPH human insulin) as the basal insulin. HUMALOG achieved glycemic control comparable to Humulin R, as measured by HbA1c (see Table 7), and both treatment groups had a comparable incidence of hypoglycemia. In a 9-month, crossover study of prepubescent children (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 HbA1c, and incidence of hypoglycemia, regardless of treatment group.

Type 1 Diabetes – Adults Continuous Subcutaneous Insulin Infusion To evaluate the administration of HUMALOG U-100 via external insulin pumps, two open-label, crossover design studies were performed in patients with type 1 diabetes. 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 HbA1c 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 HbA1c 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. Type 1 Diabetes – Pediatric Continuous Subcutaneous Insulin Infusion A randomized, 16-week, open-label, parallel design, study of children and adolescents 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 HbA1c and comparable rates of hypoglycemia after 16 weeks of treatment (see Table 8). Infusion site reactions were similar between groups.

The most common side effects of HUMALOG include: low blood sugar (hypoglycemia), reactions at the injection site, skin thickening or pits at the injection site (lipodystrophy), itching (pruritis), rash. These are not all the possible side effects of HUMALOG. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1800-FDA-1088. General information about the safe and effective use of HUMALOG. Medicines are sometimes prescribed for purposes other than those listed in a Patient Information leaflet. You can ask your pharmacist or healthcare provider for information about HUMALOG that is written for health professionals. Do not use HUMALOG for a condition for which it was not prescribed. Do not give or share HUMALOG with other people, even if they also have diabetes. It may harm them. What are the ingredients in HUMALOG? Active ingredient: insulin lispro Inactive ingredients: glycerin, dibasic sodium phosphate, metacresol, zinc oxide (zinc ion), trace amounts of phenol and water for injection Instructions for Use HUMALOG KwikPen® insulin lispro injection (rDNA origin) 100 units/mL, 3 mL pen Read the Instructions for Use before you start taking HUMALOG® and each time you get another KwikPen®. 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 HUMALOG KwikPen 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. HUMALOG KwikPen (“Pen”) is a disposable prefilled pen containing 300 units of HUMALOG. You can give yourself more than 1 dose from the Pen. Each turn (click) of the Dose Knob dials 1 unit of insulin. You can give from 1 to 60 units in a single injection. If your dose is more than60 units, you will need to give yourself more than 1 injection. The Plunger only moves a little with each injection, and you may not notice that it moves. The Plunger will only reach the end of the cartridge when you have used all 300 units in the Pen. This Pen is not recommended for use by the blind or visually impaired without the help ofsomeone trained to use the Pen. How to recognize your HUMALOG KwikPen Pen color: Dark blue Dose Knob: Dark blue Labels: White label with burgundy stripe Supplies you will need to give your injection HUMALOG KwikPen KwikPen compatible Needle (Becton, Dickinson and Company Pen Needles recommended) Alcohol swab Gauze Preparing your Pen Wash your hands with soap and water. Check your Pen to make sure you are taking the right type of insulin. This is especially important if you use more than 1 type of insulin. Do not use your Pen past the expiration date printed on the Label or for more than 28 days after you first start using the Pen. Always use a new needle for each injection to help prevent infections and blocked needles. Do not reuse or share your needles with other people. You may give otherpeople a serious infection or get a serious infection from them. Step 1: Pull the Pen Cap straight off. Do not remove the Pen Label. Wipe the Rubber Seal with an alcohol swab. Step 2: Check the liquid in the Pen. HUMALOG should look clear and colorless. Do not use if it is cloudy, colored, or has particles or clumps in it. Step 3: Select a new Needle. Pull off the Paper Tab from the Outer Needle Shield. Step 4: Push the capped Needle straight onto the Pen and twist the Needle on until it is tight. Step 5: Pull off the Outer Needle Shield. Do not throw it away. Pull off the Inner Needle Shield and throw it away. Priming your Pen Prime before each injection. Priming your Pen means removing the air from the Needle and Cartridge that may collect during normal use and ensures that the Pen is working correctly. If you do not prime before each injection, you may get too much or too little insulin. Step 6: To prime your Pen, turn the Dose Knob to select 2 units. Step 7: Hold your Pen with the Needle pointing up. Tap the Cartridge Holder gently to collect air bubbles at the top. Step 8: Continue holding your Pen with Needle pointing up. Push the Dose Knob in until it stops, and “0” is seen in the Dose Window. Hold the Dose Knob in and count to 5 slowly. You should see insulin at the tip of the Needle. If you do not see insulin, repeat priming steps 6 to 8, no more than 4 times. If you still do not see insulin, change the Needle and repeat priming steps 6 to 8. Small air bubbles are normal and will not affect your dose. Selecting your dose You can give from 1 to 60 units in a single injection. If your dose is more than 60 units, you will need to give more than 1 injection. If you need help with dividing up your dose the right way, ask your healthcare provider. Use a new Needle for each injection and repeat the priming step. Step 9: Turn the Dose Knob to select the number of units you need to inject. The Dose Indicator should line up with your dose. The Pen dials 1 unit at a time. The Dose Knob clicks as you turn it. Do not dial your dose by counting the clicks. You may dial the wrong dose. This may lead to you getting too much insulin or not enough insulin. The dose can be corrected by turning the Dose Knob in either direction until the correct dose lines up with the Dose Indicator. The even numbers (for example, 12) are printed on the dial. The odd numbers, (for example, 25) after the number 1, are shown as full lines. Always check the number in the Dose Window to make sure you have dialed the correct dose. The Pen will not let you dial more than the number of units left in the Pen. If you need to inject more than the number of units left in the Pen, you may either: Inject the amount left in your Pen and then use a new Pen to give the rest of your dose, or get a new Pen and inject the full dose. It is normal to see a small amount of insulin left in the Pen that you can not inject. Giving your injection Inject your insulin as your healthcare provider has shown you. Change (rotate) your injection site for each injection. Do not try to change your dose while injecting. Step 10: Choose your injection site. HUMALOG is injected under the skin (subcutaneously) of your stomach area, buttocks, upper legs or upper arms. Wipe your skin with an alcohol swab, and let your skin dry before you inject your dose. Step 11: Insert the Needle into your skin. Push the Dose Knob all the way in. Continue to hold the Dose Knob in and slowly count to 5 before removing the Needle. Do not try to inject your insulin by turning the Dose Knob. You will not receive your insulin by turning the Dose Knob. Step 12: Pull the Needle out of your skin. A drop of insulin at the Needle tip is normal. It will not affect your dose. Check the number in the Dose Window. If you see “0” in the Dose Window, you have received the full amount you dialed. If you do not see “0” in the Dose Window, do not redial. Insert the Needle into your skin and finish your injection. If you still do not think you received the full amount you dialed for your injection, do not start over or repeat the injection. Monitor your blood glucose as instructed by your healthcare provider. If you normally need to give 2 injections for your full dose, be sure to give your second injection. The Plunger only moves a little with each injection, and you may not notice that it moves. If you see blood after you take the Needle out of your skin, press the injection site lightly with a piece of gauze or an alcohol swab. Do not rub the area. After your injection Step 13: Carefully replace the Outer Needle Shield. Step 14: Unscrew the capped Needle and throw it away (see Disposing of Pens and Needles section). Do not store the Pen with the Needle attached to prevent leaking, blocking the Needle, and air from entering the Pen. Step 15: Replace the Pen Cap by lining up the Cap Clip with the Dose Indicator and pushing straight on. Disposing of Pens and Needles Put your used needles in a FDA-cleared sharps disposal container right away after use. Do not throw away (dispose of) loose needles 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, eak-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. The used Pen may be discarded in your household trash after you have removed the needle. Storing your Pen Unused Pens Store unused Pens in the refrigerator at 36°F to 46°F (2°C to 8°C). Do not freeze your insulin. Do not use if it has been frozen. Unused Pens may be used until the expiration date printed on the Label, if the Pen has been kept in the refrigerator. In-use Pen Store the Pen you are currently using at room temperature [up to 86°F (30°C)]. Keep away from heat and light. Throw away the HUMALOG Pen you are using after 28 days, even if it still has insulin left in it. General information about the safe and effective use of your Pen Keep your Pen and needles out of the reach of children. Do not use your Pen if any part looks broken or damaged. Always carry an extra Pen in case yours is lost or damaged. Troubleshooting If you can not remove the Pen Cap, gently twist the cap back and forth, and then pull the cap straight off. If the Dose Knob is hard to push: Pushing the Dose Knob more slowly will make it easier to inject. Your Needle may be blocked. Put on a new Needle and prime the Pen. You may have dust, food, or liquid inside the Pen. Throw the Pen away and get a new Pen.

Supplies needed to give your injection a HUMALOG vial a U-100 insulin syringe and needle 2 alcohol swabs 1 sharps container for throwing away used needles and syringes. See “Disposing of used needles and syringes” at the end of these instructions. 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 or needle for each injection to help ensure sterility and prevent 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 fromthem. 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: Hold the syringe with the needle pointing up. Pull down on the Plunger until the tip of the Plunger 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 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 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 vial’s Rubber Stopper. 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. HUMALOG starts acting fast, so give your injection within 15 minutes before or right after you eat a meal. Change (rotate) your injection site for each injection. 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. You may see a drop of insulin at the needle tip. This is normal and does not affect the dose you just received. 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 Change your insertion site every 3 days. Change the insulin in the reservoir at least every 7 days, 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.

SIDE EFFECTS Observed With HUMALOG U-100 The following adverse reactions are discussed elsewhere: Hypoglycemia [see WARNINGS AND PRECAUTIONS]. Hypokalemia [see WARNINGS AND PRECAUTIONS]. Clinical Trial 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. The frequencies of Treatment-Emergent Adverse Events during HUMALOG clinical trials in patients with type 1 diabetes mellitus and type 2 diabetes mellitus are listed in the tables below. Table 1: Treatment-Emergent Adverse Events in Patients with Type 1 Diabetes Mellitus (adverse events with frequency ≥5%) Events, n (%) Lispro Regular human insulin (n=81) (n=86) Flu syndrome 28 (34.6) 28 (32.6) Pharyngitis 27 (33.3) 29 (33.7) Rhinitis 20 (24.7) 25 (29.1) Headache 24 (29.6) 19 (22.1) Pain 16 (19.8) 14 (16.3) Cough increased 14 (17.3) 15 (17.4) Infection 11 (13.6) 18 (20.9) Nausea 5 (6.2) 13 (15.1) Accidental injury 7 (8.6) 10 (11.6) Surgical procedure 5 (6.2) 12 (14.0) Fever 5 (6.2) 10 (11.6) Abdominal pain 6 (7.4) 7 (8.1) Asthenia 6 (7.4) 7 (8.1) Bronchitis 6 (7.4) 6 (7.0) Diarrhea 7 (8.6) 5 (5.8) Dysmenorrhea 5 (6.2) 6 (7.0) Myalgia 6 (7.4) 5 (5.8) Urinary tract infection 5 (6.2) 4 (4.7) Table 2: Treatment-Emergent Adverse Events in Patients with Type 2 Diabetes Mellitus (adverse events with frequency ≥5%) Events, n (%) Lispro(n=714) Regular human insulin(n=709) Headache 63 (11.6) 66 (9.3) Pain 77 (10.8) 71 (10.0) Infection 72 (10.1) 54 (7.6) Pharyngitis 47 (6.6) 58 (8.2) Rhinitis 58 (8.1) 47 (6.6) Flu syndrome 44 (6.2) 58 (8.2) Surgical procedure 53 (7.4) 48 (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. 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. Rotate insulin injection or infusion sites within the same region to reduce the risk of lipodystrophy [see DOSAGE AND ADMINISTRATION]. Weight Gain Weight gain can occur with insulin therapy, including HUMALOG, and has been attributed to the anabolic effects of insulin and the decrease in glucosuria. Peripheral Edema Insulin, 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 children and adolescents with type 1 diabetes, adverse event reports 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 adverse events were infusion site erythema and infusion site reaction. Allergic Reactions Local Allergy As with any insulin therapy, 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. In some instances, these reactions may be related to factors other than insulin, such as irritants in a skin cleansing agent or poor injection technique. 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]. 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. Postmarketing Experience HUMALOG U-100 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 postapproval use [see PATIENT INFORMATION]. DRUG INTERACTIONS Drugs That May Increase The Risk Of Hypoglycemia The risk of hypoglycemia associated with HUMALOG use may be increased when co-administered with antidiabetic agents, salicylates, sulfonamide antibiotics, monoamine oxidase inhibitors, fluoxetine, pramlintide, disopyramide, fibrates, propoxyphene, pentoxifylline, ACE inhibitors, angiotensin II receptor blocking agents, and somatostatin analogs (e.g., octreotide). Dose adjustment and increased frequency of glucose monitoring may be required when HUMALOG is co-administered with these drugs. Drugs That May Decrease The Blood Glucose Lowering Effect Of HUMALOG The glucose lowering effect of HUMALOG may be decreased when co-administered with corticosteroids, isoniazid, niacin, estrogens, oral contraceptives, phenothiazines, danazol, diuretics, sympathomimetic agents (e.g., epinephrine, albuterol, terbutaline), somatropin, atypical antipsychotics, glucagon, protease inhibitors, and thyroid hormones. Dose adjustment and increased frequency of glucose monitoring may be required when HUMALOG is co-administered with these drugs. Drugs That May Increase Or Decrease The Blood Glucose Lowering Effect Of HUMALOG The glucose lowering effect of HUMALOG may be increased or decreased with co-administered with beta-blockers, clonidine, lithium salts, and alcohol. Pentamidine may cause hypoglycemia, which may sometimes be followed by hyperglycemia. Dose adjustment and increased frequency of glucose monitoring may be required when HUMALOG is co-administered with these drugs. Drugs That May Blunt Signs And Symptoms Of Hypoglycemia The signs and symptoms of hypoglycemia [see WARNINGS AND PRECAUTIONS] may be blunted when beta-blockers, clonidine, guanethidine, and reserpine are co-administered with HUMALOG.

WARNINGS Included as part of the "PRECAUTIONS" Section PRECAUTIONS Never Share A HUMALOG KwikPen, Cartridge, Reusable Pen Compatible With Lilly 3 mL Cartridges1, Or Syringe Between Patients HUMALOG KwikPens, cartridges, and reusable pens compatible with Lilly 3 mL cartridges must never be shared between patients, even if the needle is changed. Patients using HUMALOG vials must never share needles or syringes with another person. Sharing poses a risk for transmission of blood-borne pathogens. Hyper-Or Hypoglycemia With Changes In Insulin Regimen 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 cautiously and under close medical supervision and the frequency of blood glucose monitoring should be increased. Hypoglycemia Hypoglycemia is the most common adverse reaction associated with insulins, including HUMALOG. 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). Hypoglycemia can happen suddenly and symptoms may differ in each individual 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 medications that block the sympathetic nervous system (e.g., beta-blockers) [see DRUG INTERACTIONS], or in patients who experience recurrent hypoglycemia. Risk Factors For Hypoglycemia The risk of hypoglycemia after an injection is related to the duration of action of the insulin and, in general, is highest when the glucose lowering effect of the insulin is maximal. As with all insulin preparations, the glucose lowering effect time course of HUMALOG may vary in different individuals or at different times in the same individual and depends on many conditions, including the area of injection as well as the injection site blood supply and temperature [see CLINICAL PHARMACOLOGY]. 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. Hypoglycemia Due To Medication Errors Accidental mix-ups between basal insulin products and other insulins, particularly rapid-acting insulins, have been reported. To avoid medication errors between HUMALOG and other insulins, instruct patients to always check the insulin label before each injection. Do not transfer HUMALOG U-200 from the HUMALOG KwikPen to a syringe. The markings on the insulin syringe will not measure the dose correctly and can result in overdosage and severe hypoglycemia [see DOSAGE AND ADMINISTRATION and Hypoglycemia]. Hypersensitivity Reactions Severe, life-threatening, generalized allergy, including anaphylaxis, can occur with insulin products, including HUMALOG. If hypersensitivity reactions occur, discontinue HUMALOG; treat per standard of care and monitor until symptoms and signs resolve [see ADVERSE REACTIONS]. HUMALOG is contraindicated in patients who have had hypersensitivity reactions to HUMALOG or any of its excipients [see CONTRAINDICATIONS]. Hypokalemia All insulin products, including HUMALOG, 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 if indicated (e.g., patients using potassium-lowering medications, patients taking medications sensitive to serum potassium concentrations). 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 HUMALOG, 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. Hyperglycemia And Ketoacidosis Due To Insulin Pump Device Malfunction Malfunction of the insulin pump or insulin infusion set or insulin degradation can rapidly lead to hyperglycemia and ketoacidosis. Prompt identification and correction of the cause of hyperglycemia or ketosis is necessary. Interim subcutaneous injections with HUMALOG may be required. Patients using continuous subcutaneous insulin infusion pump therapy must be trained to administer insulin by injection and have alternate insulin therapy available in case of pump failure [see HOW SUPPLIED and PATIENT INFORMATION]. Patient Counseling Infprmation Advise the patient to read the FDA-approved patient labeling (PATIENT INFORMATION and Instructions for Use). Never Share A HUMALOG KwikPen, Cartridge, Reusable Pen Compatible With Lilly 3 mL Cartridges, Or Syringe Between Patients Advise patients that they must never share a HUMALOG KwikPen, 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. 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]. Hypersensitivity Reactions Advise patients that hypersensitivity reactions have occurred with HUMALOG. Inform patients on the symptoms of hypersensitivity reactions [see WARNINGS AND PRECAUTIONS]. Medication Errors Instruct patients to always check the insulin label before each injection to avoid mix-ups between insulin products. Inform patients that HUMALOG U-200 contains 2 times as much insulin in 1 mL as HUMALOG U-100. Inform patients that the HUMALOG U-200 KwikPen dose window shows the number of units of HUMALOG U-200 to be injected and that no dose conversion is required. Instruct patients to NOT transfer HUMALOG U-200 from the HUMALOG KwikPen to a syringe. The markings on the syringe will not measure the dose correctly and this can result in overdosage and severe hypoglycemia. Administration Instruction For HUMALOG U-200 Instruct patients to NOT mix HUMALOG U-200 with any other insulin. Women Of Reproductive Potential Advise females of reproductive potential with diabetes to inform their doctor if they are pregnant or are contemplating pregnancy [see Use In Specific Populations]. Instructions For Patients Using Continuous Subcutaneous Insulin Pumps Patients using external pump infusion therapy should be trained appropriately. The following insulin pumps have been tested in HUMALOG clinical trials conducted by Eli Lilly and Company. Disetronic® H-Tron® plus V100, D-Tron® and D-Tronplus® with Disetronic Rapid infusion sets2 MiniMed® Models 506, 507 and 508 and Polyfin® infusion sets3 HUMALOG is recommended for use in pump systems suitable for insulin infusion such as MiniMed, Disetronic, and other equivalent pumps. Before using HUMALOG in a pump system, read the pump label to make sure the pump is indicated for continuous delivery of fast-acting insulin. HUMALOG is recommended for use in any reservoir and infusion sets that are compatible with insulin and the specific pump. Please see recommended reservoir and infusion sets in the pump manual. Do not use HUMALOG U-200 in an external insulin pump. To avoid insulin degradation, infusion set occlusion, and loss of the preservative (metacresol), insulin in the reservoir should be replaced at least every 7 days; infusion sets and infusion set insertion sites should be changed at least every 3 days. Insulin exposed to temperatures higher than 98.6°F (37°C) should be discarded. 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. Infusion sites that are erythematous, pruritic, or thickened should be reported to the healthcare professional, and a new site selected because continued infusion may increase the skin reaction or alter the absorption of HUMALOG. Pump or infusion set malfunctions or insulin degradation can lead to rapid hyperglycemia and ketosis. This is especially pertinent for rapid acting insulin analogs that are more rapidly absorbed through skin and have a shorter duration of action. Prompt identification and correction of the cause of hyperglycemia or ketosis is necessary. Problems include pump malfunction, infusion set occlusion, leakage, disconnection or kinking, and degraded insulin. Less commonly, hypoglycemia from pump malfunction may occur. If these problems cannot be promptly corrected, patients should resume therapy with subcutaneous insulin injection and contact their healthcare professionals [see DOSAGE AND ADMINISTRATION and HOW SUPPLIED]. 1 3 mL cartridge is for use in Eli Lilly and Company’s HumaPen® Luxura® HD insulin delivery device, and Disetronic DTRON ® and D-TRON® Plus pumps. 2 Disetronic®, H-Tron®, D-Tron®, and D-Tronplus® are registered trademarks of Roche Diagnostics GmbH. 3 MiniMed® and Polyfin® are registered trademarks of MiniMed, Inc.

Nonclinical Toxicology 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 (0.16, 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. Use In Specific Populations Pregnancy Pregnancy Category B. All pregnancies have a background risk of birth defects, loss, or other adverse outcome regardless of drug exposure. This background risk is increased in pregnancies complicated by hyperglycemia and may be decreased with good metabolic control. It is essential for patients with diabetes or history of gestational diabetes to maintain good metabolic control before conception and throughout pregnancy. In patients with diabetes or gestational diabetes insulin requirements may decrease during the first trimester, generally increase during the second and third trimesters, and rapidly decline after delivery. Careful monitoring of glucose control is essential in these patients. Therefore, female patients should be advised to tell their physicians if they intend to become, or if they become pregnant while taking HUMALOG. Although there are limited clinical studies of the use of HUMALOG in pregnancy, published studies with human insulins suggest that optimizing overall glycemic control, including postprandial control, before conception and during pregnancy improves fetal outcome. In a combined fertility and embryo-fetal development study, female rats were 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, 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 0.24 times the human subcutaneous dose of 1 unit/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. Nursing Mothers It is unknown whether insulin lispro is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when HUMALOG is administered to a nursing woman. Use of HUMALOG is compatible with breastfeeding, but women with diabetes who are lactating may require adjustments of their insulin doses. Pediatric Use HUMALOG is approved for use in children for subcutaneous daily injections [see Clinical Studies]. Only the U-100 formulation of HUMALOG is approved for use in children by continuous subcutaneous infusion in insulin pumps. HUMALOG has not been studied in pediatric patients younger than 3 years of age. HUMALOG has not been studied in pediatric patients with type 2 diabetes. As in adults, the dosage of HUMALOG must be individualized in pediatric patients based on metabolic needs and results of frequent monitoring of blood glucose. Geriatric Use Of the total number of subjects (n=2834) in eight clinical studies of HUMALOG, twelve percent (n=338) were 65 years of age or over. The majority of these had type 2 diabetes. HbA1c 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. 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]. 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].
