Mounjaro Injection, Solution
FDA Label NDC 50090-8024

• In both male and female rats, tirzepatide causes dose-dependent and treatment-duration-dependent thyroid C-cell tumors at clinically relevant exposures. It is unknown whether MOUNJARO causes thyroid C-cell tumors, including medullary thyroid carcinoma (MTC), in humans as human relevance of tirzepatide-induced rodent thyroid C-cell tumors has not been determined [see Warnings and Precautions (5.1) and Nonclinical Toxicology (13.1)].
• MOUNJARO is contraindicated in patients with a personal or family history of MTC or in patients with Multiple Endocrine Neoplasia syndrome type 2 (MEN 2) [see Contraindications (4)]. Counsel patients regarding the potential risk for MTC with the use of MOUNJARO and inform them of symptoms of thyroid tumors (e.g., a mass in the neck, dysphagia, dyspnea, persistent hoarseness). Routine monitoring of serum calcitonin or using thyroid ultrasound is of uncertain value for early detection of MTC in patients treated with MOUNJARO [see Contraindications (4) and Warnings and Precautions (5.1)].

MOUNJARO^® is indicated as an adjunct to diet and exercise to improve glycemic control in adults and pediatric patients 10 years of age and older with type 2 diabetes mellitus.

• The recommended starting dosage of MOUNJARO is 2.5 mg injected subcutaneously once weekly [see Dosage and Administration (2.2)]. Follow the dosage escalation below to reduce the risk of gastrointestinal adverse reactions [see Warnings and Precautions (5.6) and Adverse Reactions (6.1)]. The 2.5 mg dosage is for treatment initiation and is not intended for glycemic control.
• After 4 weeks, increase the dosage to 5 mg injected subcutaneously once weekly.
• If additional glycemic control is needed, increase the dosage in 2.5 mg increments after at least 4 weeks on the current dose. The maximum dosage of MOUNJARO is:
  • 15 mg injected subcutaneously once weekly in adults.
  • 10 mg injected subcutaneously once weekly in pediatric patients.
  • If a dose is missed, instruct patients to administer MOUNJARO as soon as possible within 4 days (96 hours) after the missed dose. If more than 4 days have passed, skip the missed dose and administer the next dose on the regularly scheduled day. In each case, patients can then resume their regular once weekly dosing schedule.
  • The day of weekly administration can be changed, if necessary, as long as the time between the two doses is at least 3 days (72 hours).

• Inform patients and their caregiver(s) which MOUNJARO presentation (e.g., vial, pre-filled single-dose pen, single-patient-use KwikPen) they will receive and ensure they receive training appropriate for that specific presentation. If the prescribed MOUNJARO presentation changes, ensure patients and caregivers receive appropriate training and instruct them to consult the Instructions for Use for the newly prescribed presentation.
• Prior to initiation, train patients and their caregiver(s) on proper injection technique for the prescribed MOUNJARO presentation [see Instructions for Use]. After training, a patient may self-inject MOUNJARO if the healthcare provider determines that it can be properly administered, except for the following:
  • MOUNJARO KwikPen is not recommended for self-administration by pediatric patients.
  • MOUNJARO KwikPen is not recommended for self-administration by those who are visually impaired.
  • Instruct patients using MOUNJARO vials to use a syringe appropriate for dose administration (e.g., a 1 mL syringe capable of measuring a 0.5 mL or 0.6 mL dose) and always use a new syringe and needle for each injection.
  • Administer MOUNJARO once weekly, any time of day, with or without meals.
  • Inject MOUNJARO subcutaneously in the abdomen, thigh, or another person should inject in the back of the upper arm.
  • Rotate injection sites with each dose.
  • Inspect MOUNJARO visually before use. It should appear clear and colorless to slightly yellow. Do not use MOUNJARO if particulate matter or discoloration is seen.
  • When using MOUNJARO with insulin, administer as separate injections and never mix. It is acceptable to inject MOUNJARO and insulin in the same body region, but the injections should not be adjacent to each other.

Injection: Clear, colorless to slightly yellow solution in pre-filled single-dose pens, single-dose vials, multi-dose vials, or single-patient-use KwikPens, each available in the following strengths. The multi-dose vials and single-patient-use KwikPen each contain 4 doses:

MOUNJARO is contraindicated in patients with:

• A personal or family history of medullary thyroid carcinoma (MTC) or in patients with Multiple Endocrine Neoplasia syndrome type 2 (MEN 2) [see Warnings and Precautions (5.1)].
• Known serious hypersensitivity to tirzepatide or any of the excipients in MOUNJARO. Serious hypersensitivity reactions, including anaphylaxis and angioedema, have been reported with MOUNJARO [see Warnings and Precautions (5.4)].

In both sexes of rats, tirzepatide caused a dose-dependent and treatment-duration-dependent increase in the incidence of thyroid C-cell tumors (adenomas and carcinomas) in a 2-year study at clinically relevant plasma exposures [see Nonclinical Toxicology (13.1)]. It is unknown whether MOUNJARO causes thyroid C-cell tumors, including medullary thyroid carcinoma (MTC), in humans as human relevance of tirzepatide-induced rodent thyroid C-cell tumors has not been determined.

MOUNJARO is contraindicated in patients with a personal or family history of MTC or in patients with MEN 2. Counsel patients regarding the potential risk for MTC with the use of MOUNJARO and inform them of symptoms of thyroid tumors (e.g., a mass in the neck, dysphagia, dyspnea, persistent hoarseness).

Routine monitoring of serum calcitonin or using thyroid ultrasound is of uncertain value for early detection of MTC in patients treated with MOUNJARO. Such monitoring may increase the risk of unnecessary procedures, due to the low test specificity for serum calcitonin and a high background incidence of thyroid disease. Significantly elevated serum calcitonin values may indicate MTC and patients with MTC usually have calcitonin values >50 ng/L. If serum calcitonin is measured and found to be elevated, the patient should be further evaluated. Patients with thyroid nodules noted on physical examination or neck imaging should also be further evaluated.

Acute pancreatitis, including fatal and non-fatal hemorrhagic or necrotizing pancreatitis, has been observed in patients treated with GLP-1 receptor agonists, or MOUNJARO [see Adverse Reactions (6)].

After initiation of MOUNJARO, observe patients carefully for signs and symptoms of acute pancreatitis, which may include persistent or severe abdominal pain (sometimes radiating to the back) and which may or may not be accompanied by nausea or vomiting. If pancreatitis is suspected, discontinue MOUNJARO and initiate appropriate management.

Patients receiving MOUNJARO in combination with an insulin secretagogue (e.g., sulfonylurea) or insulin may have an increased risk of hypoglycemia, including severe hypoglycemia [see Adverse Reactions (6.1), Drug Interactions (7.1)].

The risk of hypoglycemia may be lowered by a reduction in the dose of sulfonylurea (or other concomitantly administered insulin secretagogue) or insulin. Inform patients using these concomitant medications of the risk of hypoglycemia and educate them on the signs and symptoms of hypoglycemia.

Serious hypersensitivity reactions (e.g., anaphylaxis, angioedema) have been reported in patients treated with MOUNJARO. If hypersensitivity reactions occur, discontinue use of MOUNJARO; treat promptly per standard of care, and monitor until signs and symptoms resolve. Do not use in patients with a previous serious hypersensitivity reaction to tirzepatide or any of the excipients in MOUNJARO [see Contraindications (4), Adverse Reactions (6.2)].

Anaphylaxis and angioedema have been reported with GLP-1 receptor agonists. Use caution in patients with a history of angioedema or anaphylaxis with a GLP-1 receptor agonist because it is unknown whether such patients will be predisposed to these reactions with MOUNJARO.

There have been postmarketing reports of acute kidney injury, in some cases requiring hemodialysis, in patients treated with GLP-1 receptor agonists, or MOUNJARO. The majority of the reported events occurred in patients who experienced gastrointestinal adverse reactions leading to dehydration such as nausea, vomiting, or diarrhea [see Adverse Reactions (6)].

Monitor renal function in patients reporting adverse reactions to MOUNJARO that could lead to volume depletion, especially during dosage initiation and escalation of MOUNJARO.

Use of MOUNJARO has been associated with gastrointestinal adverse reactions, sometimes severe [see Adverse Reactions (6)]. In the pool of placebo-controlled trials in adults, severe gastrointestinal adverse reactions occurred more frequently among patients receiving MOUNJARO (5 mg 1.3%, 10 mg 0.4%, 15 mg 1.2%) than placebo (0.9%). Severe gastrointestinal adverse reactions have also been reported postmarketing with GLP-1 receptor agonists.

MOUNJARO is not recommended in patients with severe gastroparesis.

Rapid improvement in glucose control has been associated with a temporary worsening of diabetic retinopathy. MOUNJARO has not been studied in patients with non-proliferative diabetic retinopathy requiring acute therapy, proliferative diabetic retinopathy, or diabetic macular edema. Patients with a history of diabetic retinopathy should be monitored for progression of diabetic retinopathy.

Acute events of gallbladder disease such as cholelithiasis or cholecystitis have been reported in GLP-1 receptor agonist trials and postmarketing.

In MOUNJARO placebo-controlled clinical trials in adults, acute gallbladder disease (cholelithiasis, biliary colic, and cholecystectomy) was reported by 0.6% of MOUNJARO-treated patients and 0% of placebo-treated patients. If cholelithiasis is suspected, gallbladder diagnostic studies and appropriate clinical follow-up are indicated.

MOUNJARO delays gastric emptying [see Clinical Pharmacology (12.2)]. There have been rare postmarketing reports of pulmonary aspiration in patients receiving GLP-1 receptor agonists undergoing elective surgeries or procedures requiring general anesthesia or deep sedation who had residual gastric contents despite reported adherence to preoperative fasting recommendations.

Available data are insufficient to inform recommendations to mitigate the risk of pulmonary aspiration during general anesthesia or deep sedation in patients taking MOUNJARO, including whether modifying preoperative fasting recommendations or temporarily discontinuing MOUNJARO could reduce the incidence of retained gastric contents. Instruct patients to inform healthcare providers prior to any planned surgeries or procedures if they are taking MOUNJARO.

Never share MOUNJARO KwikPen between patients, even if the pen needle is changed. Sharing poses a risk for transmission of blood-borne pathogens.

The following serious adverse reactions are described below or elsewhere in the prescribing information:

• Risk of Thyroid C-cell Tumors [see Warnings and Precautions (5.1)]
• Acute Pancreatitis [see Warnings and Precautions (5.2)]
• Hypoglycemia with Concomitant Use of Insulin Secretagogues or Insulin [see Warnings and Precautions (5.3)]
• Hypersensitivity Reactions [see Warnings and Precautions (5.4)]
• Acute Kidney Injury Due to Volume Depletion [see Warnings and Precautions (5.5)]
• Severe Gastrointestinal Adverse Reactions [see Warnings and Precautions (5.6)]
• Diabetic Retinopathy Complications in Patients with a History of Diabetic Retinopathy [see Warnings and Precautions (5.7)]
• Acute Gallbladder Disease [see Warnings and Precautions (5.8)]
• Pulmonary Aspiration During General Anesthesia or Deep Sedation [see Warnings and Precautions (5.9)]

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

Adverse Reactions in the Clinical Trials of Adults with Type 2 Diabetes Mellitus

Pool of Two Placebo-Controlled Clinical Trials in Adults

The data in Table 1 are derived from 2 placebo-controlled trials [1 monotherapy trial (SURPASS-1) and 1 trial in combination with basal insulin with or without metformin (SURPASS-5)] in adult patients with type 2 diabetes mellitus [see Clinical Studies (14.2, 14.4)]. These data reflect exposure of 718 patients to MOUNJARO and a mean duration of exposure to MOUNJARO of 36.6 weeks. The mean age of patients was 58 years, 4% were 75 years or older and 54% were male. The population was 57% White, 27% Asian, 13% American Indian or Alaska Native, and 3% Black or African American; 25% identified as Hispanic or Latino ethnicity. At baseline, patients had type 2 diabetes mellitus for an average of 9.1 years with a mean HbA1c of 8.1%. As assessed by baseline fundoscopic examination, 13% of the population had retinopathy. At baseline, eGFR was ≥90 mL/min/1.73 m² in 53%, 60 to 90 mL/min/1.73 m² in 39%, 45 to 60 mL/min/1.73 m² in 7%, and 30 to 45 mL/min/1.73 m² in 1% of patients.

Pool of Seven Controlled Clinical Trials

Adverse reactions were also evaluated in a larger pool of adult patients with type 2 diabetes mellitus participating in seven controlled clinical trials which included two placebo-controlled trials (SURPASS-1 and -5), three trials of MOUNJARO in combination with metformin, sulfonylureas, and/or SGLT2 Inhibitors (SURPASS-2, -3, -4) [see Clinical Studies (14.3)] and two additional trials conducted in Japan. In this pool, a total of 5119 adult patients with type 2 diabetes mellitus were treated with MOUNJARO for a mean duration of 48.1 weeks. The mean age of patients was 58 years, 4% were 75 years or older and 58% were male. The population was 65% White, 24% Asian, 7% American Indian or Alaska Native, and 3% Black or African American; 38% identified as Hispanic or Latino ethnicity. At baseline, patients had type 2 diabetes mellitus for an average of 9.1 years with a mean HbA1c of 8.3%. As assessed by baseline fundoscopic examination, 15% of the population had retinopathy. At baseline, eGFR was ≥90 mL/min/1.73 m² in 52%, 60 to 90 mL/min/1.73 m² in 40%, 45 to 60 mL/min/1.73 m² in 6%, and 30 to 45 mL/min/1.73 m² in 1% of patients.

Common Adverse Reactions

Table 1 shows common adverse reactions, not including hypoglycemia, associated with the use of MOUNJARO in the pool of placebo-controlled trials in adults. These adverse reactions occurred more commonly on MOUNJARO than on placebo and occurred in at least 5% of patients treated with MOUNJARO.

In the pool of seven clinical trials in adults, the types and frequency of common adverse reactions, not including hypoglycemia, were similar to those listed in Table 1.

Gastrointestinal Adverse Reactions

In the pool of placebo-controlled trials in adults, gastrointestinal adverse reactions occurred more frequently among patients receiving MOUNJARO than placebo (placebo 20.4%, MOUNJARO 5 mg 37.1%, MOUNJARO 10 mg 39.6%, MOUNJARO 15 mg 43.6%). More patients receiving MOUNJARO 5 mg (3.0%), MOUNJARO 10 mg (5.4%), and MOUNJARO 15 mg (6.6%) discontinued treatment due to gastrointestinal adverse reactions than patients receiving placebo (0.4%). The majority of reports of nausea, vomiting, and/or diarrhea occurred during dose escalation and decreased over time.

The following gastrointestinal adverse reactions were reported more frequently in MOUNJARO-treated adult patients than placebo-treated patients (frequencies listed, respectively, as: placebo; 5 mg; 10 mg; 15 mg): eructation (0.4%, 3.0%, 2.5%, 3.3%), flatulence (0%, 1.3%, 2.5%, 2.9%), gastroesophageal reflux disease (0.4%, 1.7%, 2.5%, 1.7%), abdominal distension (0.4%, 0.4%, 2.9%, 0.8%).

Other Adverse Reactions in Adults

Hypoglycemia

Table 2 summarizes the incidence of hypoglycemic events in the placebo-controlled trials in adults.

Hypoglycemia was more frequent when MOUNJARO was used in combination with a sulfonylurea [see Clinical Studies (14)]. In an adult clinical trial up to 104 weeks of treatment, when administered with a sulfonylurea, hypoglycemia (glucose level <54 mg/dL) occurred in 13.8%, 9.9%, and 12.8%, and severe hypoglycemia occurred in 0.5%, 0%, and 0.6% of patients treated with MOUNJARO 5 mg, 10 mg, and 15 mg, respectively.

Acute Pancreatitis

In clinical studies, 14 events of acute pancreatitis were confirmed by adjudication in 13 MOUNJARO-treated adult patients (0.23 patients per 100 years of exposure) versus 3 events in 3 comparator-treated patients (0.11 patients per 100 years of exposure).

Heart Rate Increase

In the pool of placebo-controlled trials, treatment of adults with MOUNJARO resulted in a mean increase in heart rate of 2 to 4 beats per minute compared to a mean increase of 1 beat per minute in placebo-treated patients. Episodes of sinus tachycardia, associated with a concomitant increase from baseline in heart rate of ≥15 beats per minute, also were reported in 4.3%, 4.6%, 5.9% and 10% of subjects treated with placebo, MOUNJARO 5 mg, 10 mg, and 15 mg, respectively. For patients enrolled in Japan, these episodes were reported in 7% (3/43), 7.1% (3/42), 9.3% (4/43), and 23% (10/43) of patients treated with placebo, MOUNJARO 5 mg, 10 mg, and 15 mg, respectively. The clinical relevance of heart rate increases is uncertain.

Hypersensitivity Reactions

Hypersensitivity reactions have been reported with MOUNJARO in the pool of placebo-controlled trials in adults, sometimes severe (e.g., urticaria and eczema); hypersensitivity reactions were reported in 3.2% of MOUNJARO-treated patients compared to 1.7% of placebo-treated patients.

In the pool of seven clinical trials in adults, hypersensitivity reactions occurred in 106/2,570 (4.1%) of MOUNJARO-treated adult patients with anti-tirzepatide antibodies and in 73/2,455 (3.0%) of MOUNJARO-treated patients who did not develop anti-tirzepatide antibodies. In the clinical trial in pediatric patients 10 years of age and older, hypersensitivity reactions occurred in 2/50 (4%) of MOUNJARO-treated pediatric patients with anti-tirzepatide antibodies and in 0/43 (0%) of MOUNJARO-treated pediatric patients who did not develop anti-tirzepatide antibodies [see Clinical Pharmacology (12.6)].

Injection Site Reactions

In the pool of placebo-controlled trials in adults, injection site reactions were reported in 3.2% of MOUNJARO-treated patients compared to 0.4% of placebo-treated patients.

In the pool of seven clinical trials, injection site reactions occurred in 119/2,570 (4.6%) of MOUNJARO-treated adult patients with anti-tirzepatide antibodies and in 18/2,455 (0.7%) of MOUNJARO-treated adult patients who did not develop anti-tirzepatide antibodies. In the clinical trial in pediatric patients 10 years of age and older, injection site reactions occurred in 3/50 (6%) of MOUNJARO-treated pediatric patients with anti-tirzepatide antibodies and in 0/43 (0%) of MOUNJARO-treated pediatric patients who did not develop anti-tirzepatide antibodies [see Clinical Pharmacology (12.6)].

Acute Gallbladder Disease

In the pool of placebo-controlled clinical trials in adults, acute gallbladder disease (cholelithiasis, biliary colic and cholecystectomy) was reported by 0.6% of MOUNJARO-treated patients and 0% of placebo-treated patients.

Dysesthesia

In the pool of placebo-controlled clinical trials in adults, dysesthesia was reported by 0.4%, 0.4%, and 0.4% of patients treated with MOUNJARO 5 mg, 10 mg, and 15 mg, respectively. No events were reported by patients receiving placebo.

Dysgeusia

In the pool of placebo-controlled clinical trials in adults, dysgeusia was reported by 0.1% of MOUNJARO-treated patients and 0% of placebo-treated patients.

Laboratory Abnormalities

Amylase and Lipase Increase

In the pool of placebo-controlled adult clinical trials, treatment with MOUNJARO resulted in mean increases from baseline in serum pancreatic amylase concentrations of 33% to 38% and serum lipase concentrations of 31% to 42%. Placebo-treated patients had a mean increase from baseline in pancreatic amylase of 4% and no changes were observed in lipase. The clinical significance of elevations in lipase or amylase with MOUNJARO is unknown in the absence of other signs and symptoms of pancreatitis.

Adverse Reactions in the Clinical Trial of Pediatric Patients 10 Years of Age and Older with Type 2 Diabetes Mellitus

MOUNJARO was administered to 97 pediatric patients 10 years of age and older with type 2 diabetes mellitus for a mean duration of 39.9 weeks [see Clinical Studies (14.5)]. The mean age was 15 years and 61% of patients were female. The population was 58% White, 11% Black or African American, 6% Asian, 20% American Indian or Alaska Native, and 5% were other races; 66% identified as Hispanic or Latino ethnicity. At baseline, pediatric patients had type 2 diabetes mellitus for an average of 2.4 years with a mean HbA1c of 8.0%.

The incidences of adverse reactions reported in pediatric patients treated with MOUNJARO 5 mg and 10 mg subcutaneously once-weekly were consistent with those described above for adult patients with type 2 diabetes mellitus with the exception of a higher incidence of vomiting, abdominal pain, and hypoglycemia. During the 30-week placebo-controlled period of the study, vomiting occurred in 3%, 16%, and 12% of patients and abdominal pain occurred in 9%, 22%, and 15% of patients treated with placebo, MOUNJARO 5 mg, and 10 mg, respectively.

No severe hypoglycemia episodes were reported during the trial. Table 3 summarizes the incidence of hypoglycemic events with blood glucose <54 mg/dL in the trial.

Risk Summary

Available data with MOUNJARO use in pregnant women are insufficient to evaluate for a drug-related risk of major birth defects, miscarriage, or other adverse maternal or fetal outcomes. There are risks to the mother and fetus associated with poorly controlled diabetes in pregnancy (see Clinical Considerations). Based on animal reproduction studies, there may be risks to the fetus from exposure to tirzepatide during pregnancy. MOUNJARO should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

In pregnant rats administered tirzepatide during organogenesis, fetal growth reductions and fetal abnormalities occurred at clinical exposure in maternal rats based on AUC. In rabbits administered tirzepatide during organogenesis, fetal growth reductions were observed at clinically relevant exposures based on AUC. These adverse embryo/fetal effects in animals coincided with pharmacological effects on maternal weight and food consumption (see Data).

The estimated background risk of major birth defects is 6–10% in women with pre-gestational diabetes with an HbA1c >7% and has been reported to be as high as 20–25% in women with an 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

Animal Data

In pregnant rats given twice weekly subcutaneous doses of 0.02, 0.1, and 0.5 mg/kg tirzepatide (0.03-, 0.07-, and 0.5-fold the MRHD of 15 mg once weekly based on AUC) during organogenesis, increased incidences of external, visceral, and skeletal malformations, increased incidences of visceral and skeletal developmental variations, and decreased fetal weights coincided with pharmacologically-mediated reductions in maternal body weights and food consumption at 0.5 mg/kg. In pregnant rabbits given once weekly subcutaneous doses of 0.01, 0.03, or 0.1 mg/kg tirzepatide (0.01-, 0.06-, and 0.2-fold the MRHD) during organogenesis, pharmacologically-mediated effects on the gastrointestinal system resulting in maternal mortality or abortion in a few rabbits occurred at all dose levels. Reduced fetal weights associated with decreased maternal food consumption and body weights were observed at 0.1 mg/kg. In a pre- and post-natal study in rats administered subcutaneous doses of 0.02, 0.10, or 0.25 mg/kg tirzepatide twice weekly from implantation through lactation, F₁ pups from F₀ maternal rats given 0.25 mg/kg tirzepatide had statistically significant lower mean body weight when compared to controls from post-natal day 7 through post-natal day 126 for males and post-natal day 56 for females.

Risk Summary

In a single-dose clinical lactation study, the concentration of tirzepatide in breast milk was found to be either undetectable or low compared to the maternal administered dose (see Data). There are no available data on the effects of tirzepatide on the breastfed infant or on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for MOUNJARO and any potential adverse effects on the breastfed infant from MOUNJARO or from the underlying maternal condition.

Data

Following subcutaneous administration of a single 5 mg dose to 11 healthy lactating adult females, the concentration of tirzepatide in breast milk was found to be undetectable (limit of detection in breast milk 4 ng/mL) in 164/171 samples assayed. The cumulative amount of tirzepatide detected in the remaining 7 breast milk samples over the 28-day sampling window was equivalent to less than 0.02% of the maternal administered dose, with the last measurable concentrations occurring 5 days post-dose. The AUC of tirzepatide in breast milk could not be calculated, due to insufficient quantifiable concentrations.

Contraception

Use of MOUNJARO may reduce the efficacy of oral hormonal contraceptives due to delayed gastric emptying. This delay is largest after the first dose and diminishes over time. Advise patients using oral hormonal contraceptives to switch to a non-oral contraceptive method or add a barrier method of contraception for 4 weeks after initiation and for 4 weeks after each dose escalation with MOUNJARO [see Drug Interactions (7.2) and Clinical Pharmacology (12.2, 12.3)].

First and Second-Phase Insulin Secretion

Tirzepatide enhances the first- and second-phase insulin secretion. (Figure 1)

Figure 1: Mean insulin concentration at 0-120 minutes during hyperglycemic clamp at baseline and Week 28

Figure 1 (Moun Uspi F1 V1)

Insulin Sensitivity

Tirzepatide increases insulin sensitivity, as demonstrated in a hyperinsulinemic euglycemic clamp study after 28 weeks of treatment.

Glucagon Secretion

Tirzepatide reduces fasting and postprandial glucagon concentrations. Tirzepatide 15 mg reduced fasting glucagon concentration by 28% and glucagon AUC after a mixed meal by 43%, compared with no change for placebo after 28 weeks of treatment.

Gastric Emptying

Tirzepatide delays gastric emptying. The delay is largest after the first dose and this effect diminishes over time. Tirzepatide slows post-meal glucose absorption, reducing postprandial glucose.

Absorption

Following subcutaneous administration, the time to maximum plasma concentration of tirzepatide ranges from 8 to 72 hours. The mean absolute bioavailability of tirzepatide following subcutaneous administration is 80%. Similar exposure was achieved with subcutaneous administration of tirzepatide in the abdomen, thigh, or upper arm.

Distribution

The mean apparent steady-state volume of distribution of tirzepatide following subcutaneous administration in patients with type 2 diabetes mellitus is approximately 10.3 L. Tirzepatide is highly bound to plasma albumin (99%).

Elimination

The apparent population mean clearance of tirzepatide is 0.061 L/h with an elimination half-life of approximately 5 days, enabling once-weekly dosing.

Metabolism

Tirzepatide is metabolized by proteolytic cleavage of the peptide backbone, beta-oxidation of the C20 fatty diacid and amide hydrolysis.

Excretion

The primary excretion routes of tirzepatide metabolites are via urine and feces. Intact tirzepatide is not observed in urine or feces.

Specific Populations

The intrinsic factors of age, gender, race, ethnicity, or body weight do not have a clinically relevant effect on the PK of tirzepatide.

Pediatric Patients

A population pharmacokinetic analysis was conducted for tirzepatide 5 mg and 10 mg using data from 93 pediatric patients 10 years of age and older with type 2 diabetes mellitus. The tirzepatide exposure in pediatric patients was within the range observed in adult patients.

Patients with Renal Impairment

Renal impairment does not impact the pharmacokinetics of tirzepatide. The pharmacokinetics of tirzepatide after a single 5 mg dose was evaluated in patients with different degrees of renal impairment (mild, moderate, severe, ESRD) compared with subjects with normal renal function. This was also shown for patients with both type 2 diabetes mellitus and renal impairment based on data from clinical studies [see Use in Specific Populations (8.6)].

Patients with Hepatic Impairment

Hepatic impairment does not impact the pharmacokinetics of tirzepatide. The pharmacokinetics of tirzepatide after a single 5 mg dose was evaluated in patients with different degrees of hepatic impairment (mild, moderate, severe) compared with subjects with normal hepatic function [see Use in Specific Populations (8.7)].

Drug Interactions Studies

Potential for Tirzepatide to Influence the Pharmacokinetics of Other Drugs

In vitro studies have shown low potential for tirzepatide to inhibit or induce CYP enzymes, and to inhibit drug transporters.

MOUNJARO delays gastric emptying and thereby has the potential to impact the absorption of concomitantly administered oral medications [see Drug Interactions (7.2)].

The impact of tirzepatide on gastric emptying was greatest after a single dose of 5 mg and diminished after subsequent doses.

Following a first dose of tirzepatide 5 mg, acetaminophen maximum concentration (C_max) was reduced by 50%, and the median peak plasma concentration (t_max) occurred 1 hour later. After coadministration at week 4, there was no meaningful impact on acetaminophen C_max and t_max. Overall acetaminophen exposure (AUC_0-24hr) was not influenced.

Following administration of a combined oral contraceptive (0.035 mg ethinyl estradiol and 0.25 mg norgestimate) in the presence of a single dose of tirzepatide 5 mg, mean C_max of ethinyl estradiol, norgestimate, and norelgestromin was reduced by 59%,66%, and 55%, while mean AUC was reduced by 20%, 21%, and 23%, respectively. A delay in t_max of 2.5 to 4.5 hours was observed.

Add-on to metformin

SURPASS-2 (NCT03987919) was a 40-week open-label trial (double-blind with respect to MOUNJARO dose assignment) that randomized 1879 adult patients with type 2 diabetes mellitus with inadequate glycemic control on stable doses of metformin alone to the addition of subcutaneous MOUNJARO 5 mg, MOUNJARO 10 mg, or MOUNJARO 15 mg once weekly or subcutaneous semaglutide 1 mg once weekly.

Patients had a mean age of 57 years and 47% were men. The mean duration of type 2 diabetes mellitus was 8.6 years, and the mean BMI was 34 kg/m². Overall, 83% were White, 4% were Black or African American, and 1% were Asian; 70% identified as Hispanic or Latino ethnicity.

Treatment with MOUNJARO 10 mg and 15 mg once weekly for 40 weeks resulted in a statistically significant reduction in HbA1c compared with semaglutide 1 mg once weekly (see Table 5 and Figure 2).

Add-on to metformin with or without SGLT2 inhibitor

SURPASS-3 (NCT03882970) was a 52-week open-label trial that randomized 1444 adult patients with type 2 diabetes mellitus with inadequate glycemic control on stable doses of metformin with or without SGLT2 inhibitor to the addition of subcutaneous MOUNJARO 5 mg, MOUNJARO 10 mg, MOUNJARO 15 mg once weekly, or insulin degludec 100 units/mL once daily. In this trial, 32% of patients were on SGLT2 inhibitor. Insulin degludec was initiated at 10 units once daily and adjusted weekly throughout the trial using a treat-to-target algorithm based on self-measured fasting blood glucose values. At Week 52, 26% of patients randomized to insulin degludec achieved the fasting serum glucose target of <90 mg/dL, and the mean daily insulin degludec dose was 49 U (0.5 U per kilogram).

Patients had a mean age of 57 years, and 56% were men. The mean duration of type 2 diabetes mellitus was 8.4 years, and the mean baseline BMI was 34 kg/m². Overall, 91% were White, 3% were Black or African American, and 5% were Asian; 29% identified as Hispanic or Latino ethnicity.

Treatment with MOUNJARO 10 mg and 15 mg once weekly for 52 weeks resulted in a statistically significant reduction in HbA1c compared with daily insulin degludec (see Table 6).

Add-on to 1-3 oral anti-hyperglycemic agents (metformin, sulfonylurea, or SGLT-2 inhibitor)

SURPASS-4 (NCT03730662) was a 104-week open-label trial (52-week primary endpoint) that randomized 2002 adult patients with type 2 diabetes mellitus with increased cardiovascular risk to subcutaneous MOUNJARO 5 mg, MOUNJARO 10 mg, MOUNJARO 15 mg once weekly, or insulin glargine 100 units/mL once daily (1:1:1:3 ratio) on a background of metformin (95%) and/or sulfonylureas (54%) and/or SGLT2 inhibitors (25%).

Patients had a mean age of 64 years, and 63% were men. The mean duration of type 2 diabetes mellitus was 11.8 years, and the mean baseline BMI was 33 kg/m². Overall, 82% were White, 4% were Black or African American, and 4% were Asian; 48% identified as Hispanic or Latino ethnicity. Across all treatment groups, 87% had a history of cardiovascular disease. At baseline, eGFR was ≥90 mL/min/1.73 m² in 43%, 60 to 90 mL/min/1.73 m² in 40%, 45 to 60 mL/min/1.73 m² in 10%, and 30 to 45 mL/min/1.73 m² in 6% of patients.

Insulin glargine was initiated at 10 U once daily and adjusted weekly throughout the trial using a treat-to-target algorithm based on self-measured fasting blood glucose values. At Week 52, 30% of patients randomized to insulin glargine achieved the fasting serum glucose target of <100 mg/dL, and the mean daily insulin glargine dose was 44 U (0.5 U per kilogram).

Treatment with MOUNJARO 10 mg and 15 mg once weekly for 52 weeks resulted in a statistically significant reduction in HbA1c compared with insulin glargine once daily (see Table 7).

Risk of Thyroid C-Cell Tumors

Inform patients that MOUNJARO causes thyroid C-cell tumors in rats and that the human relevance of this finding has not been determined. Counsel patients to report symptoms of thyroid tumors (e.g., a lump in the neck, persistent hoarseness, dysphagia, or dyspnea) to their healthcare provider [see Boxed Warning and Warnings and Precautions (5.1)].

Acute Pancreatitis

Inform patients of the potential risk for acute pancreatitis and its symptoms: severe abdominal pain that sometimes radiates to the back, and which may or may not be accompanied by nausea or vomiting. Instruct patients to discontinue MOUNJARO promptly and contact their physician if pancreatitis is suspected [see Warnings and Precautions (5.2)].

Hypoglycemia with Concomitant Use of Insulin Secretagogues or Insulin

Inform patients that the risk of hypoglycemia is increased when MOUNJARO is used with an insulin secretagogue (such as a sulfonylurea) or insulin. Educate patients on the signs and symptoms of hypoglycemia [see Warnings and Precautions (5.3)].

Hypersensitivity Reactions

Inform patients that serious hypersensitivity reactions have been reported with use of MOUNJARO. Advise patients on the symptoms of hypersensitivity reactions and instruct them to stop taking MOUNJARO and seek medical advice promptly if such symptoms occur [see Warnings and Precautions (5.4)].

Acute Kidney Injury Due to Volume Depletion

Inform patients of the potential risk of acute kidney injury due to dehydration associated with gastrointestinal adverse reactions. Advise patients to take precautions to avoid fluid depletion. Inform patients of the signs and symptoms of acute kidney injury and instruct them to promptly report any of these signs or symptoms or persistent (or extended) nausea, vomiting, and diarrhea to their healthcare provider [see Warnings and Precautions (5.5)].

Severe Gastrointestinal Adverse Reactions

Inform patients of the potential risk of severe gastrointestinal adverse reactions. Instruct patients to contact their healthcare provider if they have severe or persistent gastrointestinal symptoms [see Warnings and Precautions (5.6)].

Diabetic Retinopathy Complications in Patients with a History of Diabetic Retinopathy

Inform patients to contact their healthcare provider if changes in vision are experienced during treatment with MOUNJARO [see Warnings and Precautions (5.7)].

Acute Gallbladder Disease

Inform patients of the risk of acute gallbladder disease. Instruct patients to contact their healthcare provider for appropriate clinical follow-up if gallbladder disease is suspected [see Warnings and Precautions (5.8)].

Pulmonary Aspiration During General Anesthesia or Deep Sedation

Inform patients that MOUNJARO may cause their stomach to empty more slowly which may lead to complications with anesthesia or deep sedation during planned surgeries or procedures. Instruct patients to inform healthcare providers prior to any planned surgeries or procedures if they are taking MOUNJARO [see Warnings and Precautions (5.9)].

Never Share a MOUNJARO KwikPen Between Patients

Advise patients that they must never share a MOUNJARO KwikPen with another person, even if the pen needle is changed, because doing so carries a risk for transmission of blood-borne pathogens [see Warnings and Precautions (5.10)].

Pregnancy

Advise a pregnant woman of the potential risk to a fetus. Advise women to inform their healthcare provider if they are pregnant or intend to become pregnant [see Use in Specific Populations (8.1)].

Contraception

Use of MOUNJARO may reduce the efficacy of oral hormonal contraceptives. Advise patients using oral hormonal contraceptives to switch to a non-oral contraceptive method or add a barrier method of contraception for 4 weeks after initiation and for 4 weeks after each dose escalation with MOUNJARO [see Drug Interactions (7.2), Use in Specific Populations (8.3), and Clinical Pharmacology (12.3)].

Administration

Instruct patients how to prepare and administer the correct dose of MOUNJARO and assess their ability to inject subcutaneously to ensure the proper administration of MOUNJARO. Instruct patients using MOUNJARO vials to always use a new syringe and needle for each injection. Use a syringe appropriate for dose administration (e.g., a 1 mL syringe capable of measuring a 0.5 mL or 0.6 mL dose). Notify the patient of which MOUNJARO presentation they will be receiving and ensure training is appropriate for the specific MOUNJARO presentation. Advise patients to refer to the IFU in case of any change in the presentation. Advise caregivers that MOUNJARO KwikPen is not recommended for self-administration by pediatric patients or those with visual impairment unless their healthcare provider determines the patient can properly administer. [see Dosage and Administration (2.2)].

Missed Doses

Inform patients if a dose is missed, it should be administered as soon as possible within 4 days after the missed dose. If more than 4 days have passed, the missed dose should be skipped and the next dose should be administered on the regularly scheduled day. In each case, inform patients to resume their regular once weekly dosing schedule [see Dosage and Administration (2.1)].

MOU-0011-USPI-20260422

The following adverse reactions have been reported during post-approval use of MOUNJARO. 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.

Hypersensitivity: anaphylaxis, angioedema

Gastrointestinal: acute pancreatitis, hemorrhagic and necrotizing pancreatitis sometimes resulting in death, ileus, intestinal obstruction, severe constipation including fecal impaction

Pulmonary: Pulmonary aspiration has occurred in patients receiving GLP-1 receptor agonists undergoing elective surgeries or procedures requiring general anesthesia or deep sedation

Renal: acute renal failure or worsening of chronic renal failure, sometimes requiring hemodialysis

Skin and Subcutaneous Tissue: alopecia

When initiating MOUNJARO, consider reducing the dose of concomitantly administered insulin secretagogues (e.g., sulfonylureas) or insulin to reduce the risk of hypoglycemia [see Warnings and Precautions (5.3)].

MOUNJARO delays gastric emptying and thereby has the potential to impact the absorption of concomitantly administered oral medications. Caution should be exercised when oral medications are concomitantly administered with MOUNJARO.

Monitor patients on oral medications dependent on threshold concentrations for efficacy and those with a narrow therapeutic index (e.g., warfarin) when concomitantly administered with MOUNJARO.

Advise patients using oral hormonal contraceptives to switch to a non-oral contraceptive method or add a barrier method of contraception for 4 weeks after initiation and for 4 weeks after each dose escalation with MOUNJARO. Hormonal contraceptives that are not administered orally should not be affected [see Use in Specific Populations (8.3) and Clinical Pharmacology (12.2, 12.3)].

The safety and effectiveness of MOUNJARO as an adjunct to diet and exercise to improve glycemic control in pediatric patients 10 years of age and older with type 2 diabetes mellitus have been established. Use of MOUNJARO for this indication is supported by a 30-week, randomized, double-blind, placebo-controlled trial with a 22-week open label extension in 99 pediatric patients [see Clinical Studies (14.5)].

Adverse reactions reported in pediatric patients 10 years of age and older treated with MOUNJARO were similar to those reported in adults with the exception of a higher incidence of vomiting, abdominal pain, and hypoglycemia [see Adverse Reactions (6.1)].

The safety and effectiveness of MOUNJARO have not been established in pediatric patients less than 10 years of age.

In the pool of seven clinical trials, 1539 (30.1%) MOUNJARO-treated patients were 65 years of age or older, and 212 (4.1%) MOUNJARO-treated patients were 75 years of age or older at baseline.

No overall differences in safety or efficacy were detected between these patients and younger patients, but greater sensitivity of some older individuals cannot be ruled out.

No dosage adjustment of MOUNJARO is recommended for patients with renal impairment. In subjects with renal impairment including end-stage renal disease (ESRD), no change in tirzepatide pharmacokinetics (PK) was observed [see Clinical Pharmacology (12.3)]. Monitor renal function when initiating or escalating doses of MOUNJARO in patients with renal impairment reporting severe adverse gastrointestinal reactions [see Warnings and Precautions (5.5)].

No dosage adjustment of MOUNJARO is recommended for patients with hepatic impairment. In a clinical pharmacology study in subjects with varying degrees of hepatic impairment, no change in tirzepatide PK was observed [see Clinical Pharmacology (12.3)].

In the event of an overdosage, consider contacting the Poison Help line (1-800-222-1222) or a medical toxicologist for additional overdosage management recommendations. Initiate appropriate supportive treatment according to the patient's clinical signs and symptoms. A period of observation and treatment for these symptoms may be necessary, taking into account the half-life of tirzepatide of approximately 5 days.

MOUNJARO (tirzepatide) injection, for subcutaneous use, contains tirzepatide, a once weekly GIP receptor and GLP-1 receptor agonist. Tirzepatide is based on the GIP sequence and contains aminoisobutyric acid (Aib) in positions 2 and 13, a C-terminal amide, and Lys residue at position 20 that is attached to 1,20-eicosanedioic acid via a linker. The molecular weight is 4813.53 Da and the empirical formula is C₂₂₅H₃₄₈N₄₈O₆₈.

Structural formula:

Structural Formula (Moun Uspi Chem Struc)

MOUNJARO is a clear, colorless to slightly yellow, sterile solution for subcutaneous use. Each single-dose pen or single-dose vial contains a 0.5 mL solution of 2.5 mg, 5 mg, 7.5 mg, 10 mg, 12.5 mg, or 15 mg of tirzepatide and the following excipients: sodium chloride (4.1 mg), sodium phosphate dibasic heptahydrate (0.7 mg), and water for injection. Each multi-dose vial or single-patient-use KwikPen contains 2.4 mL of solution, which provides 4 doses of 2.5 mg, 5 mg, 7.5 mg, 10 mg, 12.5 mg, or 15 mg of tirzepatide per 0.6 mL. Each dose contains the following excipients: benzyl alcohol (5.4 mg), glycerin (4.8 mg), phenol (1.08 mg), sodium chloride (1.05 mg), sodium phosphate dibasic heptahydrate (0.8 mg), and water for injection. Hydrochloric acid solution and/or sodium hydroxide solution may have been added to adjust the pH. MOUNJARO has a pH of 6.5 to 7.5.

Each single-patient-use KwikPen contains additional volume to allow for device priming.

Tirzepatide is a GIP receptor and GLP-1 receptor agonist. It contains a C20 fatty diacid that enables albumin binding and prolongs the half-life. Tirzepatide selectively binds to and activates both the GIP and GLP-1 receptors, the targets for native GIP and GLP-1.

Tirzepatide enhances first- and second-phase insulin secretion, and reduces glucagon levels, both in a glucose-dependent manner.

Tirzepatide lowers fasting and postprandial glucose concentration, decreases food intake, and reduces body weight in patients with type 2 diabetes mellitus.

The pharmacokinetics of tirzepatide is similar between healthy subjects and patients with type 2 diabetes mellitus. Steady-state plasma tirzepatide concentrations were achieved following 4 weeks of once weekly administration. Tirzepatide exposure increases in a dose-proportional manner.

The observed incidence of anti-drug antibodies is highly dependent on the sensitivity and specificity of the assay. Differences in assay methods preclude meaningful comparisons of the incidence of anti-drug antibodies in the trials described below with the incidence of anti-drug antibodies in other trials.

During the 40- to 104-week treatment periods with ADA sampling conducted up to 44 to 108 weeks in seven clinical trials in adults with type 2 diabetes mellitus [see Clinical Studies (14)], 51% (2,570/5,025) of MOUNJARO-treated patients developed anti-tirzepatide antibodies. In these trials, anti-tirzepatide antibody formation in 34% and 14% of MOUNJARO-treated adult patients showed cross-reactivity to native GIP or native GLP-1, respectively.

Of the 2,570 MOUNJARO-treated patients who developed anti-tirzepatide antibodies during the treatment periods in these seven trials, 2% and 2% developed neutralizing antibodies against tirzepatide activity on the GIP or GLP-1 receptors, respectively, and 0.9% and 0.4% developed neutralizing antibodies against native GIP or GLP-1, respectively.

During the 30-week double-blind placebo-controlled period of the glycemic control trial in pediatric patients 10 years of age or older with type 2 diabetes mellitus [see Clinical Studies (14.5)], 30/61 (49%) of MOUNJARO-treated pediatric patients developed anti-tirzepatide antibodies. Anti-tirzepatide antibodies showed cross reactivity to native GIP or native GLP-1 in 26% and 8% of MOUNJARO-treated pediatric patients, respectively. There were no neutralizing antibodies against tirzepatide activity on the GIP or GLP-1 receptors. No pediatric patients developed neutralizing antibodies against native GIP or GLP-1.

There was no identified clinically significant effect of anti-tirzepatide antibodies on pharmacokinetics or effectiveness of MOUNJARO. More MOUNJARO-treated adult and pediatric patients who developed anti-tirzepatide antibodies experienced hypersensitivity reactions or injection site reactions than those who did not develop these antibodies [see Adverse Reactions (6.1)].

A 2-year carcinogenicity study was conducted with tirzepatide in male and female rats at doses of 0.15, 0.50, and 1.5 mg/kg (0.1-, 0.4-, and 1-fold the MRHD of 15 mg once weekly based on AUC) administered by subcutaneous injection twice weekly. A statistically significant increase in thyroid C-cell adenomas was observed in males (≥0.5 mg/kg) and females (≥0.15 mg/kg), and a statistically significant increase in thyroid C-cell adenomas and carcinomas combined was observed in males and females at all doses examined. In a 6-month carcinogenicity study in rasH2 transgenic mice, tirzepatide at doses of 1, 3, and 10 mg/kg administered by subcutaneous injection twice weekly was not tumorigenic.

Tirzepatide was not genotoxic in a rat bone marrow micronucleus assay.

In fertility and early embryonic development studies, male and female rats were administered twice weekly subcutaneous doses of 0.5, 1.5, or 3 mg/kg (0.3-, 1-, and 2-fold and 0.3-, 0.9-, and 2-fold, respectively, the MRHD of 15 mg once weekly based on AUC). No effects of tirzepatide were observed on sperm morphology, mating, fertility, and conception. In female rats, an increase in the number of females with prolonged diestrus and a decrease in the mean number of corpora lutea resulting in a decrease in the mean number of implantation sites and viable embryos was observed at all dose levels. These effects were considered secondary to the pharmacological effects of tirzepatide on food consumption and body weight.

The effectiveness of MOUNJARO as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus was established in five trials. In these trials, MOUNJARO was studied as monotherapy (SURPASS-1); as an add-on to metformin, sulfonylureas, and/or sodium-glucose co-transporter 2 inhibitors (SGLT2 inhibitors) (SURPASS-2, -3, and -4); and in combination with basal insulin with or without metformin (SURPASS-5). In these trials, MOUNJARO (5 mg, 10 mg, and 15 mg given subcutaneously once weekly) was compared with placebo, semaglutide 1 mg, insulin degludec, and/or insulin glargine [see Clinical Studies (14.2, 14.3, 14.4)].

In adult patients with type 2 diabetes mellitus, treatment with MOUNJARO produced a statistically significant reduction from baseline in HbA1c compared to placebo. The effectiveness of MOUNJARO was not impacted by age, gender, race, ethnicity, region, or by baseline BMI, HbA1c, diabetes duration, or renal function.

MOUNJARO 5 mg and 10 mg was studied in pediatric patients 10 years of age and older with type 2 diabetes in combination with metformin and/or basal insulin [see Clinical Studies (14.5)].

SURPASS-1 (NCT03954834) was a 40-week double-blind trial that randomized 478 adult patients with type 2 diabetes mellitus with inadequate glycemic control with diet and exercise to subcutaneous MOUNJARO 5 mg, MOUNJARO 10 mg, MOUNJARO 15 mg, or placebo once weekly.

Patients had a mean age of 54 years, and 52% were men. The mean duration of type 2 diabetes mellitus was 4.7 years, and the mean BMI was 32 kg/m². Overall, 36% were White, 35% were Asian, 25% were American Indians/Alaska Natives, and 5% were Black or African American; 43% identified as Hispanic or Latino ethnicity.

Monotherapy with MOUNJARO 5 mg, 10 mg and 15 mg once weekly for 40 weeks resulted in a statistically significant reduction in HbA1c compared with placebo (see Table 4).

SURPASS-5 (NCT04039503) was a 40-week double-blind trial that randomized 475 adult patients with type 2 diabetes mellitus with inadequate glycemic control on insulin glargine 100 units/mL, with or without metformin, to subcutaneous MOUNJARO 5 mg, MOUNJARO 10 mg, MOUNJARO 15 mg once weekly, or placebo. The dose of background insulin glargine was adjusted using a treat-to-target algorithm based on self-measured fasting blood glucose values, targeting <100 mg/dL.

Patients had a mean age of 61 years, and 56% were men. The mean duration of type 2 diabetes mellitus was 13.3 years, and the mean baseline BMI was 33 kg/m². Overall, 80% were White, 1% were Black or African American, and 18% were Asian; 5% identified as Hispanic or Latino ethnicity.

The mean dose of insulin glargine at baseline was 34, 32, 35, and 33 units/day for patients receiving MOUNJARO 5 mg, 10 mg, 15 mg, and placebo, respectively. At randomization, the initial insulin glargine dose in patients with HbA1c ≤8.0% was reduced by 20%. At week 40, mean dose of insulin glargine was 38, 36, 29, and 59 units/day for patients receiving MOUNJARO 5 mg, 10 mg, 15 mg, and placebo, respectively.

Treatment with MOUNJARO 5 mg once weekly, 10 mg once weekly and 15 mg once weekly for 40 weeks resulted in a statistically significant reduction in HbA1c compared with placebo (see Table 8).

SURPASS-PEDS (NCT05260021) was a 30-week double-blind, placebo-controlled trial with a 22-week open-label extension that randomized 99 pediatric patients 10 years of age and older with type 2 diabetes mellitus with inadequate glycemic control on metformin (69%), or basal insulin (8%), or both (23%) to receive subcutaneous MOUNJARO 5 mg, MOUNJARO 10 mg, or placebo once weekly as add-on therapy.

Patients had a mean age of 15 years, and 61% were female. The mean duration of type 2 diabetes mellitus was 2.4 years, mean HbA1c was 8.0%, mean weight was 97 kg, and the mean baseline BMI was 35 kg/m². Overall, 58% were White, 11% were Black or African American, 6% were Asian, 20% were American Indian or Alaska Native, and 5% were other races; 66% identified as Hispanic or Latino ethnicity.

Treatment with MOUNJARO 5 mg once weekly and 10 mg once weekly for 30 weeks, both pooled and individually, resulted in a statistically significant reduction in HbA1c compared with placebo (see Table 9).

Note: The needle and syringe are not included. The needle and syringe recommended by your healthcare provider may look different than the needle and syringe in this Instructions for Use.

Preparing to inject MOUNJARO

Remove the vial from the refrigerator.

Check the vial label to make sure you have the right medicine and dose, and that it has not expired.

Make sure the medicine:

is not frozen is not cloudy

is colorless to slightly yellow does not have particles

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.

Wash your hands with soap and water.

Step 1: Pull off the plastic protective cap. Do not remove the rubber stopper.	Figure (Moun Vial Ifu 3 V1)
Step 2: Wipe the rubber stopper with an alcohol swab.	Figure (Moun Vial Ifu 4 V1)
Step 3: Remove the outer wrapping from the syringe.	Figure (Moun Vial Ifu 5 V1)
Step 4: Remove the outer wrapping from the needle. The syringe that your healthcare provider recommended may have a pre-attached needle. If the needle is attached, skip to step 6.	Figure (Moun Vial Ifu 6 V1)
Step 5: Place the needle on top of the syringe and turn until it is tight and firmly attached.	Figure (Moun Vial Ifu 7 V1)
Step 6: Remove the needle shield by pulling straight off.	Figure (Moun Vial Ifu 8 V1)
Step 7: Hold the syringe in one hand with the needle pointing up. With the other hand pull down on the plunger until the plunger tip reaches the line on the syringe indicating that 0.5 mL of air has been drawn into the syringe.	Figure (Moun Vial Ifu 9 V1)
Step 8: Push the needle through the rubber stopper of the vial.	Figure (Moun Vial Ifu 10 V1)
Step 9: Push the plunger all the way in. This puts air into the vial and makes it easier to pull the solution from the vial.	Figure (Moun Vial Ifu 11 V1)
Step 10: Turn the vial and syringe upside down. Make sure that the tip of the needle is in the liquid and slowly pull the plunger down until the plunger tip is past the 0.5 mL line. If there are air bubbles, tap the syringe gently a few times to let any air bubbles rise to the top.	Figure (Moun Vial Ifu 12 V1) Figure (Moun Vial Ifu 13 V1)
Step 11: Slowly push the plunger up until the plunger tip reaches the 0.5 mL line.	Figure (Moun Vial Ifu 14 V1)
Step 12: Pull the syringe out of the rubber stopper of the vial.	Figure (Moun Vial Ifu 15 V1)

Injecting MOUNJARO

• Inject exactly as your healthcare provider has shown you. Your healthcare provider should tell you if you should pinch the skin before injecting.
• Change (rotate) your injection site 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.
• Do not mix MOUNJARO with any other medicine.
• Do not inject MOUNJARO in the same injection site used for other medicines.

Step 13: Choose your injection site. You can inject MOUNJARO under the skin (subcutaneously) of your stomach area (abdomen) or thighs. Someone else can inject in your stomach area, thighs, or the back of the upper arms.	Figure (Moun Vial Ifu 16 V1) Figure (Moun Vial Ifu 17 V1)
Step 14: Insert the needle into your skin.	Figure (Moun Vial Ifu 18 V1)
Step 15: 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 dose.	Figure (Moun Vial Ifu 19 V1)
Step 16: 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. Do not rub the area. Do not recap the needle. Recapping the needle can lead to a needle stick injury.	Figure (Moun Vial Ifu 20 V1)

Disposing of used needles and syringes

• Put your used needle and syringe in an 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 an 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.

  Storing MOUNJARO

  • Store all unopened vials in the refrigerator at 36°F to 46°F (2°C to 8°C).
  • You may store the unopened vial at room temperature up to 86°F (30°C) for up to a total of 21 days.
  • Discard the vial after a total of 21 days at room temperature.
  • Do not freeze. Do not use if MOUNJARO has been frozen.
  • Store the vial in the original carton to protect from light.
  • Throw away all opened vials after use, even if there is medicine left in the vial.

  Keep MOUNJARO vials, syringes, needles, and all medicines out of the reach of children.

  If you have any questions or problems with your MOUNJARO, contact Lilly at 1-800-Lilly-Rx (1-800-545-5979) or call your healthcare provider for help.

Figure (Mounjaro Kp 10 Dial Clicks V1)		Step 7: Slowly turn the dose knob until you hear 2 clicks and the Figure (Mounjaro Kp 11 Dial Zoom V1) extended line is shown in the dose window. This is the prime position. It can be corrected by turning the dose knob in either direction until the prime position lines up to the dose indicator.
Figure (Mounjaro Kp 12 Tap V1)		Step 8: Hold your Pen with the needle pointing up. Tap the cartridge holder gently to collect air bubbles at the top.
Figure (Mounjaro Kp 13 5sec Hold V1)		Step 9: Release some medicine into the air by pushing the dose knob in until it stops, then slowly count to 5 while holding the dose knob. The Figure (Mounjaro Kp 14 Zero Dial Zoom V1) icon must be shown in the dose window. Do not inject into your body. Your Pen has been primed if a small amount (a drop) of medicine comes out of the tip of the pen needle.

Injecting MOUNJARO

Figure (Mounjaro Kp 15 Inj Sites V1)	Step 10: Choose an injection site. You or another person can inject the medicine in your thigh or stomach (abdomen) at least 2 inches from the belly button. Another person should give you the injection in the back of your upper arm. Change (rotate) your injection site each week. You may use the same area of your body but be sure to choose a different injection site in that area.
a. Front        b. Back
Figure (Mounjaro Kp 16 Dial 1 Dose V1)	Step 11: Turn the dose knob all the way until it stops AND the Figure (Mounjaro Kp 17 Dial 1 Zoom V1) icon is in the dose window. This is your weekly dose. Do not count clicks as you select the dose.

Confirm the Figure (Mounjaro Kp 14 Zero Dial Zoom V1) icon is in the dose window. If you see the Figure (Mounjaro Kp 14 Zero Dial Zoom V1) icon in the dose window, you have received the full dose. If you do not see the Figure (Mounjaro Kp 14 Zero Dial Zoom V1) icon in the dose window, insert the needle back into your skin and finish your injection. Do not redial the dose. If you still do not think you received the full dose, do not start over or repeat the injection. See “Troubleshooting” section for more information.
