Severe hypoglycemia is a major concern for patients with diabetes on insulin therapy. Rescue requires caregivers to provide effective treatment, including glucagon injections. Dasiglucagon is a stable glucagon analog in development to be administered with the HypoPal® auto-injector for treatment of severe hypoglycemia. This phase 3 trial, ZP4207-17145, assessed the clinical efficacy and safety of 0.6 mg dasiglucagon subcutaneous (SC) administered via the HypoPal® auto-injector compared with placebo. In total, 45 eligible patients with T1D were randomized (3:1) to dasiglucagon or placebo and dosed following induced hypoglycemia. The primary endpoint was time to plasma glucose (PG) recovery, defined as first PG increase ≥20 mg/dL after treatment initiation without rescue glucose. Dasiglucagon injection provided a fast and effective increase in PG. The median time (95% CI) to recovery based on sampling time was 10 (8.0, 12.0) min for dasiglucagon and 35 (20.0, -) min for placebo (p<0.0001). The median (95% CI) estimated true time to recovery (interpolated between sampling times) was 9.3 (7.8, 10.3) min for dasiglucagon and 25.8 (19.2, 34.8) min for placebo. Nausea and vomiting are well-known side effects of glucagon and were reported in 61.8% and 29.8% of patients receiving dasiglucagon, respectively. Nausea was reported in 10% of patients receiving placebo. No safety concerns were raised for dasiglucagon.
In conclusion, dasiglucagon 0.6mg SC administered via the HypoPal® auto-injector provided fast and effective recovery from hypoglycemia. The results are consistent with previously reported results from a pivotal phase 3 trial testing dasiglucagon administered via a pre-filled syringe, NCT03378635, where a median time to recovery of 10 min was also observed.
