Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Hypoglycemia Episode Rate	Hypoglycemia episode rate, defined as average weekly number of hypoglycemic episodes (PG <70 mg/dL [3.9 mmol/L]) during Weeks 2-4 as detected by self-monitored plasma glucose (SMPG). The Week 2-4 value is the average weekly number of hypoglycemic episodes across the last 3 weeks of the treatment period. The change from Baseline to Week 2-4 is also provided. The Baseline value is the average weekly number of hypoglycemic episodes during the 2-week baseline period.	Baseline, Week 2-4 (Treatment Period 1)
Secondary	Increase in Fasting Tolerance	Increase in fasting tolerance (time from beginning of meal to the beginning of the first continuous 15-minute continuous glucose monitoring reading <70 mg/dL [3.9 mmol/L]), or the time the test ended if a continuous 15-minute CGM reading <70 mg/dL was not reached. The change from Baseline to the End of Treatment Period 1 (Week 4) is also provided. The Baseline value is the value recorded at the Screening visit.	Baseline, Week 2-4 (Treatment Period 1)
Secondary	Percent Time in Range 70-180 mg/dL	Percent time in range 70-180 mg/dL (3.9-10.0 mmol/L) during Weeks 2-4 as measured by continuous glucose monitoring. The Week 2-4 value is the average weekly percent time in range 70-180 mg/dL across the last 3 weeks of the treatment period. The change from Baseline to Week 2-4 is also provided. The Baseline value was calculated as the average percent time in range during the 14 days before randomization.	Baseline, Week 2-4 (Treatment Period 1)
Secondary	Clinically Significant Hypoglycemia Episode Rates	Clinically significant hypoglycemia episode rates during Weeks 2-4, defined as average weekly number of clinically significant hypoglycemic episodes (PG <54 mg/dL [3.0 mmol/L]), as detected by SMPG. The Week 2-4 value is the average weekly clinically significant hypoglycemia episode rate across the last 3 weeks of the treatment period. The change from Baseline to Week 2-4 is also provided. The Baseline value is the average weekly number of clinically significant hypoglycemic episodes during the 2-week baseline period.	Baseline, Week 2-4 (Treatment Period 1)
Secondary	Total Amount of Gastric Carbohydrates Administered to Treat Hypoglycemia	Total amount of gastric carbohydrates administered via nasogastric tube or gastrostomy per week to treat hypoglycemia. The Week 2-4 value is the average weekly total amount of gastric carbohydrates across the last 3 weeks of treatment period. The change from Baseline to Week 2-4 is also provided. The Baseline value is the value recorded during the 2-week Baseline period.	Baseline, Week 2-4 (Treatment Period 1)
Secondary	Rate of Gastric Carbohydrates Administrations to Treat Hypoglycemia	Rate of gastric carbohydrate administrations via nasogastric tube or gastrostomy per week to treat hypoglycemia, calculated as the number of times gastric carbohydrates were administered to treat hypoglycemia per week. The Week 2-4 value is the average weekly rate of gastric carbohydrate administrations across the last 3 weeks of the treatment period. The change from Baseline to Week 2-4 is also provided. The Baseline value is the value recorded during the 2-week Baseline period.	Baseline, Week 2-4 (Treatment Period 1)
Secondary	Extent of Hypoglycemia	Extent of hypoglycemia (area over the glucose curve [AOCglucose] below 70 mg/dL [3.9 mmol/L]) and below 54 mg/dL [3.0 mmol/L] as measured by continuous glucose monitoring. The extent of hypoglycemia was defined as the AOCglucose under the threshold divided by total duration in hours of CGM measurement. A reduction in this measure indicates a benefit. The Week 2-4 value is the average weekly extent of hypoglycemia below 70 mg/dL and below 54 mg/dL across the last 3 weeks of the treatment period. The change from Baseline to Week 2-4 is also provided. The Baseline value is the value assessed during the 14 days before randomization.	Baseline, Week 2-4 (Treatment Period 1)
