Background: During severe hypoglycemic episodes, people with diabetes depend on others to help with treatment. We compared needle-free nasal glucagon and commercially available injectable glucagon for ease of use by caregivers of people with diabetes and by others in treating simulated episodes of severe hypoglycemia.Methods: Sixteen instructed caregivers and 15 noninstructed acquaintances administered nasal and injectable glucagon to manikins, simulating unconscious people with diabetes during severe hypoglycemia episodes.Results: With nasal glucagon, 15 caregivers (94%) and 14 acquaintances (93%) administered a full dose (mean time 0.27 and 0.44 min, respectively). One caregiver and one acquaintance did not administer nasal glucagon because they did not fully depress the plunger on the device. Two caregivers deliberately administered both insulin and nasal glucagon, believing that insulin would also help the patient. With injectable glucagon, eight caregivers (50%) injected glucagon (mean time 1.89 min), but only two (13%) administered the full dose. Three acquaintances (20%) injected a partial dose of injectable glucagon (mean time 2.40 min); none gave a full dose. Errors included injecting diluent only, bending the needle, and injecting with an empty syringe. Two caregivers and one acquaintance injected insulin because they confused insulin with injectable glucagon.Conclusions: More than 90% of participants delivered full doses of nasal glucagon, while 13% and 0% of caregivers and acquaintances delivered full doses of injectable glucagon, indicating that nasal glucagon is easier for nonmedically trained people to administer. Thus, nasal glucagon has the potential to substantially improve treatment for patients experiencing a life-threatening episode of severe hypoglycemia.

In this cohort of patients with T2D, chronic glucagon receptor antagonism with LY2409021 was associated with glucose-lowering but also demonstrated increases in hepatic fat, hepatic aminotransferases, and other adverse effects.

In the present multicentre, open‐label, prospective, phase III study, we evaluated the real‐world effectiveness and ease of use of nasal glucagon (NG) in the treatment of moderate/severe hypoglycaemic events (HEs) in adults with type 1 diabetes (T1D). Patients and caregivers were taught how to use NG (3 mg) to treat moderate/severe HEs, record the time taken to awaken or return to normal status, and measure blood glucose (BG) levels over time. Questionnaires were used to collect information about adverse events and ease of use of NG. In the efficacy analysis population, 69 patients experienced 157 HEs. In 95.7% patients, HEs resolved within 30 minutes of NG administration. In all the 12 severe HEs, patients awakened or returned to normal status within 15 minutes of NG administration without additional external medical help. Most caregivers reported that NG was easy to use. Most adverse events were local and of low to moderate severity. In this study, a single, 3‐mg dose of NG demonstrated real‐life effectiveness in treating moderate and severe HEs in adults with T1D. NG was well tolerated and easy to use.

Objective:This multicenter, open-label study was designed to evaluate real-world effectiveness and ease of use of nasal glucagon (NG) in treating moderate or severe hypoglycemic events in children and adolescents with type 1 diabetes (T1D).Methods: Caregivers were trained to administer NG (3 mg) to the child/adolescent with T1D during spontaneous, symptomatic moderate or severe hypoglycemic events, observe treatment response (defined as awakening or returning to normal status within 30 minutes), and measure blood glucose (BG) levels every 15 minutes. Data regarding adverse events and ease of use were solicited using questionnaires.Results: The analysis population included 14 patients who experienced 33 moderate hypoglycemic events with neuroglycopenic symptoms and BG level ≤70 mg/dL. Patients returned to normal status within 30 minutes of NG administration in all 33 events. Mean BG levels increased from 55.5 mg/dL (range 42-70 mg/dL) at baseline to 113.7 mg/dL (range 79-173 mg/dL) within 15 minutes of NG administration. In most hypoglycemic events (93.9%), caregivers reported that NG administration was easy or very easy; they could administer NG within 30 seconds in 60.6% of events. There were no serious adverse events.Conclusions: A single 3-mg dose of NG was effective in treating moderate, symptomatic, hypoglycemic events in children and adolescents with T1D in a real-world setting. It was easy-touse and reasonably well tolerated. NG shows promise as an effective, needle-free, and userfriendly alternative to injectable glucagon.

Statistically significant increases in BP, MAP and serum lipid levels were observed with LY2409021 treatment at a dose that lowered HbA1c and glucose levels. These effects may limit the clinical utility of LY2409021 as a chronic treatment for type 2 diabetes.
