HAE was defined as 1 of the given definitions: 1) Characteristic symptoms of HAE with no home glucose monitoring performed where clinical picture included prompt resolution with food intake, subcutaneous glucagon, or intravenous glucose; 2) Characteristic symptoms of HAE with home glucose monitoring measurement of less than or equal to (=\<) 70 milligram per deciliter (mg/dL) using sponsor-provided, plasma-referenced, home glucometers (or central laboratory); 3) any glucose value =\<49 mg/dL using sponsor-provided, plasma-referenced, home glucometers (or central laboratory) with or without accompanying symptoms.
Number of Participants With Treatment Emergent Adverse Events (AEs) or Serious Adverse Events (SAEs) Baseline up to 14 days after the last dose of study drug (minimum 8 weeks to maximum of 17 weeks) An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent are events between first dose of study drug and up to 14 days after last dose that were absent before treatment or that worsened relative to pre-treatment state.
