The solution should appear clear, colorless, and free from particles. If the solution is discolored or contains particulate matter, do not use. • Administer the injection in the lower abdomen, buttocks, thigh, or outer upper arm. • Call for emergency assistance immediately after administering the dose. • If there has been no response after 15 minutes, an additional dose of ZEGALOGUE may be administered while waiting for emergency assistance. • When the patient has responded to treatment, give oral carbohydrates to restore liver glycogen and prevent recurrence of hypoglycemia. • Do not attempt to reuse ZEGALOGUE. Each ZEGALOGUE device contains a single dose of dasiglucagon and cannot be reused. 2.2 Recommended Dosage The recommended dose of ZEGALOGUE in adults and pediatric patients aged 6 years and older is 0.6 mg administered by subcutaneous injection into the lower abdomen, buttocks, thigh, or outer upper arm. If there has been no response after 15 minutes, an additional 0.6 mg dose of ZEGALOGUE from a new device may be administered.

ZEGALOGUE is contraindicated in patients with: • Pheochromocytoma because of the risk of substantial increase in blood pressure [see Warnings and Precautions (5.1) ] • Insulinoma because of the risk of hypoglycemia [see Warnings and Precautions (5.2) ] Pheochromocytoma ( 4 ) Insulinoma ( 4 )

Advise the patient and family members or caregivers to read the FDA-approved patient labeling (Patient Information and Instructions For Use). Recognition of Severe Hypoglycemia Inform patient and family members or caregivers on how to recognize the signs and symptoms of severe hypoglycemia and the risks of prolonged hypoglycemia. Administration Review the Patient Information and Instructions For Use with the patient and family members or caregivers. Serious Hypersensitivity Inform patients that allergic reactions can occur with glucagon products like ZEGALOGUE. Advise patients to seek immediate medical attention if they experience any symptoms of serious hypersensitivity reactions [see Warnings and Precautions (5.3) ].

( 7 ) • Indomethacin: In patients taking indomethacin, ZEGALOGUE may lose its ability to raise blood glucose or may produce hypoglycemia. ( 7 ) • Warfarin: ZEGALOGUE may increase the anticoagulant effect of warfarin. ( 7 )

Carcinogenesis Long-term studies in animals to evaluate carcinogenicity of dasiglucagon have not been performed. Mutagenesis Dasiglucagon was not mutagenic or clastogenic in a standard battery of genotoxicity tests: bacterial mutagenicity (Ames), human lymphocyte chromosome aberration, and rat bone marrow micronucleus. Impairment of Fertility In a fertility and early embryofetal development study in rats, dasiglucagon administered by subcutaneous injection (0.5, 2, and 8 mg/kg/day) did not impair fertility in male and female rats at exposures 179 and 269 times the human dose of 0.6 mg (based on AUC), respectively.

Risk Summary There are no available data on dasiglucagon use in pregnant women to evaluate for a drug-associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes. Untreated hypoglycemia in pregnancy can cause complications and may be fatal. In animal reproduction studies, daily subcutaneous administration of dasiglucagon to pregnant rabbits and rats during the period of organogenesis did not cause adverse developmental effects at exposures 7 and 709 times the human dose of 0.6 mg based on AUC, respectively (see Data ) . Data Animal Data In an embryo-fetal development study, pregnant rats were treated daily with subcutaneous doses of 2, 10, and 24 mg/kg/day during the period of organogenesis (gestation day 6 to 17). Maternal toxicity, in terms of decreased body weight gain, lower fetal body weight, and delayed bone ossification, was observed at ≥10 mg/kg/day (≥475 times the human dose, based on AUC). In an embryo-fetal development study, pregnant rabbits were treated daily with subcutaneous doses of 0.1, 0.3, and 1 mg/kg/day during the period of organogenesis (gestation day 6 to 19). Lower fetal body weight and delayed bone ossification were observed at 1 mg/kg/day (100 times the human dose, based on AUC), a dose that also induced maternal toxicity in terms of decreased body weight gain. At ≥0.3 mg/kg/day (≥20 times the human dose), dasiglucagon caused fetal skeletal and visceral malformations. No adverse fetal developmental effects were observed at 0.1 mg/kg/day, corresponding to exposure 7 times the human dose.

The safety and effectiveness of ZEGALOGUE for the treatment of severe hypoglycemia in patients with diabetes have been established in pediatric patients aged 6 years and above. Use of ZEGALOGUE for this indication is supported by evidence from a study in 42 pediatric patients with type 1 diabetes [see Clinical Studies (14.2) ] . The safety and effectiveness of ZEGALOGUE have not been established in pediatric patients younger than 6 years of age.

Clinical studies of ZEGALOGUE included too few patients 65 years of age and older to determine whether these patients respond differently from younger adult patients.

The following important adverse reactions are described elsewhere in the labeling: • Hypersensitivity and Allergic Reactions [see Warnings and Precautions (5.3) ] Most common adverse reactions (≥2%) associated with ZEGALOGUE are: Adults: nausea, vomiting, headache, diarrhea, and injection site pain Pediatrics: nausea, vomiting, headache, and injection site pain ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Novo Nordisk Inc., at 1-800-727-6500 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of ZEGALOGUE cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. In clinical trials, 316 adult patients with type 1 diabetes and 20 pediatric patients with type 1 diabetes were exposed to ZEGALOGUE. The data in Table 1 reflect exposure of 116 adult patients to ZEGALOGUE in 2 placebo-controlled trials (mean age 40 years). Table 2 reflects exposure of 20 pediatric patients exposed to ZEGALOGUE in a placebo-controlled trial. Eight patients were 7 to 11 years old, and 12 were 12 to 17 years old [see Clinical Studies (14) ] . Table 1.

The detection of antibody formation is highly dependent on the sensitivity and specificity of the assay. Additionally, the observed incidence of antibody (including neutralizing antibody) positivity in an assay may be influenced by several factors including assay methodology, sample handling, timing of sample collection, concomitant medications, and underlying disease. For these reasons, comparison of the incidence of antibodies to ZEGALOGUE with the incidence of antibodies to other products may be misleading. In clinical trials, 4/498 (<1%) of ZEGALOGUE-treated patients developed treatment-emergent anti-drug antibodies (ADAs). Two patients receiving a single dose of ZEGALOGUE had detectable ADAs to dasiglucagon for at least 14 months after dosing. One ADA-positive patient receiving multiple doses of ZEGALOGUE had ADAs with transient neutralizing activity and with cross-reactivity against native glucagon. Although no safety or efficacy concerns were noted for these ADA-positive subjects, it is unknown whether ADAs may affect pharmacokinetics, pharmacodynamics, safety, and/or effectiveness of the drug [see Clinical Studies (14) ] .

If overdosage occurs, the patient may experience nausea, vomiting, inhibition of GI tract motility, and/or increases in blood pressure and heart rate. In case of suspected overdosing, serum potassium may decrease and should be monitored and corrected if needed. If the patient develops a marked increase in blood pressure, phentolamine mesylate has been shown to be effective in lowering blood pressure for the short time that control would be needed. Appropriate supportive treatment should be initiated according to the patient's clinical signs and symptoms.
