Table 3 Clinically Significant Drug Interactions with ZEGALOGUE Beta-Blockers Clinical Impact: Patients taking beta-blockers may have a transient increase in pulse and blood pressure when given ZEGALOGUE. Indomethacin Clinical Impact: In patients taking indomethacin, ZEGALOGUE may lose its ability to raise blood glucose or may even produce hypoglycemia. Warfarin Clinical Impact: ZEGALOGUE may increase the anticoagulant effect of warfarin.

Advise the patient and family members or caregivers to read the FDA-approved patient labeling (Patient Information and Instructions For Use).

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) ]

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.

Three randomized, double-blind, placebo-controlled, multicenter trials were conducted in patients with type 1 diabetes. Two trials (Trial A and Trial B) were conducted in adult patients, and one trial (Trial C) was conducted in pediatric patients aged 6 to 17 years. In all 3 trials, patients were randomized to ZEGALOGUE 0.6 mg, placebo, or (in Trials A and C) glucagon for injection 1.0 mg. ZEGALOGUE and the comparators were administered as single subcutaneous injections following a controlled induction of hypoglycemia using intravenous administration of insulin. During this procedure, a plasma glucose concentration of < 60 mg/dL was targeted in Trials A and B, whereas the target was < 80 mg/dL in Trial C. The primary efficacy endpoint for all 3 trials was time to plasma glucose recovery (treatment success), defined as an increase in blood glucose of ≥20 mg/dL from time of administration, without additional intervention within 45 minutes. In Trials A and B, plasma glucose values were collected and assessed at pre-dose, and at 4, 6, 8, 10, 12, 15, 17, 20, 25, 30, 40, 45, 50, 60, 75, 90 minutes after treatment. Trial C assessed plasma glucose at the same timepoints as did Trials A and B, with the exception of the 25, 40, 50, 75 and 90-minute post-treatment timepoints. The primary hypothesis test was superiority of ZEGALOGUE versus placebo. There was no formal hypothesis test of ZEGALOGUE versus glucagon for injection.

ZEGALOGUE autoinjector and prefilled syringe are for subcutaneous injection only. Instruct patients and their caregivers on the signs and symptoms of severe hypoglycemia. Because severe hypoglycemia requires the help of others to recover, instruct the patient to inform those around them about ZEGALOGUE and its Instructions For Use. Administer ZEGALOGUE as soon as possible when severe hypoglycemia is recognized. Instruct the patient or caregiver to read the Instructions For Use at the time they receive a prescription for ZEGALOGUE. Emphasize the following instructions to the patient or caregiver: Administer ZEGALOGUE according to the printed instructions on the protective case label and the Instructions For Use. Visually inspect ZEGALOGUE prior to administration. 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.

ZEGALOGUE injection is a clear, colorless solution available as: 0.6 mg/0.6 mL single-dose autoinjector 0.6 mg/0.6 mL single-dose prefilled syringe

Dasiglucagon is a glucagon receptor agonist, which increases blood glucose concentration by activating hepatic glucagon receptors, thereby stimulating glycogen breakdown and release of glucose from the liver. Hepatic stores of glycogen are necessary for dasiglucagon to produce an antihypoglycemic effect.

After administration of ZEGALOGUE in adult patients with type 1 diabetes, the mean glucose increase from baseline at 90 minutes was 168 mg/dL (Figure 1). Figure 1 Mean plasma glucose over time in adults with type 1 diabetes administered 0.6 mg dasiglucagon In pediatric patients (7 to 17 years) with type 1 diabetes, the mean glucose increase at 60 minutes after administration of ZEGALOGUE was 162 mg/dL (Figure 2). Figure 2 Mean plasma glucose over time in pediatric patients with type 1 diabetes administered 0.6 mg dasiglucagon

Substantial Increase in Blood Pressure in Patients with Pheochromocytoma: Contraindicated in patients with pheochromocytoma because ZEGALOGUE may stimulate the release of catecholamines from the tumor. ( 4 , 5.1 ) Hypoglycemia in Patients with Insulinoma: In patients with insulinoma, administration may produce an initial increase in blood glucose, but ZEGALOGUE may stimulate exaggerated insulin release from an insulinoma and cause subsequent hypoglycemia. If a patient develops symptoms of hypoglycemia after a dose of ZEGALOGUE, give glucose orally or intravenously. ( 4 , 5.2 ) Hypersensitivity and Allergic Reactions: Allergic reactions have been reported with glucagon products and may include generalized rash, and in some cases anaphylactic shock with breathing difficulties and hypotension. ( 5.3 ) Lack of Efficacy in Patients with Decreased Hepatic Glycogen: ZEGALOGUE is effective in treating hypoglycemia only if sufficient hepatic glycogen is present. Patients in states of starvation, with adrenal insufficiency or chronic hypoglycemia may not have adequate levels of hepatic glycogen for ZEGALOGUE to be effective. Patients with these conditions should be treated with glucose. ( 5.4 )

As with all therapeutic peptides, there is a potential for immunogenicity with ZEGALOGUE. 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) ] .

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) ] .

ZEGALOGUE injection is a clear, colorless solution available as: 0.6 mg/0.6 mL single-dose autoinjector 0.6 mg/0.6 mL single-dose prefilled syringe

Dasiglucagon is a glucagon receptor agonist, which increases blood glucose concentration by activating hepatic glucagon receptors, thereby stimulating glycogen breakdown and release of glucose from the liver. Hepatic stores of glycogen are necessary for dasiglucagon to produce an antihypoglycemic effect.

After administration of ZEGALOGUE in adult patients with type 1 diabetes, the mean glucose increase from baseline at 90 minutes was 168 mg/dL (Figure 1). Figure 1 Mean plasma glucose over time in adults with type 1 diabetes administered 0.6 mg dasiglucagon In pediatric patients (7 to 17 years) with type 1 diabetes, the mean glucose increase at 60 minutes after administration of ZEGALOGUE was 162 mg/dL (Figure 2). Figure 2 Mean plasma glucose over time in pediatric patients with type 1 diabetes administered 0.6 mg dasiglucagon

Substantial Increase in Blood Pressure in Patients with Pheochromocytoma: Contraindicated in patients with pheochromocytoma because ZEGALOGUE may stimulate the release of catecholamines from the tumor. ( 4 , 5.1 ) Hypoglycemia in Patients with Insulinoma: In patients with insulinoma, administration may produce an initial increase in blood glucose, but ZEGALOGUE may stimulate exaggerated insulin release from an insulinoma and cause subsequent hypoglycemia. If a patient develops symptoms of hypoglycemia after a dose of ZEGALOGUE, give glucose orally or intravenously. ( 4 , 5.2 ) Hypersensitivity and Allergic Reactions: Allergic reactions have been reported with glucagon products and may include generalized rash, and in some cases anaphylactic shock with breathing difficulties and hypotension. ( 5.3 ) Lack of Efficacy in Patients with Decreased Hepatic Glycogen: ZEGALOGUE is effective in treating hypoglycemia only if sufficient hepatic glycogen is present. Patients in states of starvation, with adrenal insufficiency or chronic hypoglycemia may not have adequate levels of hepatic glycogen for ZEGALOGUE to be effective. Patients with these conditions should be treated with glucose. ( 5.4 )

As with all therapeutic peptides, there is a potential for immunogenicity with ZEGALOGUE. 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) ] .

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) ] .
