6.1Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of GVOKE and GVOKE VialDx cannot be directly compared to rates in the clinical trials of other drugs and may not reflect the rates observed in practice. GVOKE for Subcutaneous Use for the Treatment of Severe Hypoglycemia in Adult and Pediatric Patients 2 Aged Years and Older with Type 1 Diabetes Mellitus Adverse Reactions in Adult Patients The safety of GVOKE for subcutaneous use for the treatment of severe hypoglycemia in adults with diabetes was evaluated in two randomized, blinded, 2-way crossover studies conducted in adults with type 1 diabetes mellitus.
In total, 154 patients received a subcutaneous injection of GVOKE [see Clinical Studies ( 14.1 )] . The most common adverse reactions that occurred in 2% or more of adults treated with GVOKE during these two clinical trials are listed in Table 1. Table 1: Adverse Reactions that occurred ≥ 2% in Adult Patients with Type 1 Diabetes Mellitus Treated with GVOKE a a Adverse Reactions that occurred within 12 hours. GVOKE 1 mg dose (N = 154) Nausea 30% Vomiting 16% Injection site edema raised 1 mm or greater 7% Headache 5% Injection site pain was reported by 1% of GVOKE-treated patients.
Hypertension and tachycardia have occurred with glucagon treatment. Adverse Reactions in Pediatric Patients Aged 2 Years and Older The safety of GVOKE for the treatment of severe hypoglycemia in patients with diabetes was evaluated in one single-arm, open-label, study in 31 pediatric patients with type 1 diabetes mellitus [see Clinical Studies ( 14.2 )] . The data in Table 2 reflect the exposure of 31 pediatric patients to 0.5 mg or 1 mg of GVOKE given subcutaneously.
The most common adverse reactions that occurred in ≥2% of GVOKE-treated pediatric patients aged 2 years and older are listed in Table 2. Table 2: Adverse Reactions That Occurred ≥ 2% in GVOKE-treated Pediatric Patients Aged 2 Years and Older with Type 1 Diabetes Mellitus a a Adverse Reactions that occurred within 12 hours. 2 to 6 years of age (0.5 mg dose) N =7 6 to 12 years of age (0.5 mg dose) N = 13 12 to 18 years of age (1 mg dose) N = 11 Total N = 31 Nausea 43% 54% 36% 45% Hypoglycemia 29% 54% 27% 39% Vomiting 14% 23% 18% 19% Headache 0% 15% 0% 7% Abdominal pain 0% 8% 0% 3% Hyperglycemia 14% 8% 0% 7% Injection site discomfort 0% 8% 0% 3% Injection site reaction 0% 0% 9% 3% Urticaria 0% 8% 0% 3% GVOKE VialDx for Intravenous Use As a Diagnostic Aid in Adults The safety of GVOKE VialDx for intravenous use as a diagnostic aid in adults was evaluated in an open-label single-dose study in 83 adult healthy volunteers.
Table 3 displays the most common adverse reactions that occurred in 5% or greater in healthy volunteers who received 0.75 mg of GVOKE VialDx intravenously. Table 3: Adverse Reactions that Occurred ≥ 5 % in Adult Healthy Volunteers Who Received 0.75 mg of GVOKE VialDx for Intravenous Use as a Diagnostic Aid N=83 Nausea 37.3% Dysgeusia 18.1% Headache 10.8% Hot Flush 9.6% Dizziness 8.4%
6.2Postmarketing Experience
Additional adverse reactions have been identified during post-approval use of glucagon. Because these reactions are reported voluntarily from a population of uncertain size, it is generally not possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Necrolytic migratory erythema (NME) cases have been reported postmarketing in patients receiving continuous infusion of glucagon.
Hypoglycemia and hypoglycemic coma. Patients taking indomethacin may be more likely to experience hypoglycemia following glucagon administration [see Drug Interactions ( 7 )] .
