Personalized Hypoglycemia Outpatient Treatment - a Feasibility Study

Not Applicable

Recruiting

• Conditions: Type 2 Diabetes (T2DM); Hypoglycemia (Diabetic)

• Registration Number: NCT07094529
• Lead Sponsor: Ottawa Hospital Research Institute

Brief Summary

This study will offer two study interventions designed to bring on a mild low blood sugar (capillary blood glucose result 3.0 to 3.8 mmol/L), in order to study the effectiveness of each study participant's personal choice of treatment and first recheck time.

The two study interventions that the participant can choose to complete (one or both interventions).

Based on each participant's own experience with hypoglycemia treatment or their preferences, the participant can choose one of 4 simple carbohydrate treatment quantities, and choose one of 4 capillary blood glucose recheck times.

Detailed Description

The two study interventions that the participant can choose to complete (one or both interventions):

Study intervention A: Ride a recumbent exercise bike at participant's own desired speed, until onset of capillary blood glucose showing mild low blood glucose (hypoglycemia).

Study intervention B: Delay food intake after the participant brings and takes their routine clinical care prescribed medication(s) that decrease the blood glucose level. The participant brings in their medication(s) including sulfonylurea or insulin(s) as applicable to the study visit. In front of the study nurse, the participant takes these medication(s) at the same dose or reduced dose as defined in the study protocol. The participant is monitored until capillary blood glucose reaches the mild low blood glucose (hypoglycemia) level of 3.0 to 3.8 mmol/L.

Based on each participant's own experience with hypoglycemia treatment or their preferences, the participant can choose one of 4 simple carbohydrate treatment quantities: 8 grams, 16 grams, 20 grams, 32 grams

The participant can choose one of 4 capillary blood glucose recheck times: 15 minutes, 20 minutes, 25 minutes, 30 minutes.

Study & Design

• Study Type: INTERVENTIONAL
• Study Design: SINGLE_GROUP

Primary Outcome Measures

Name	Time	Method
To determine feasibility to recruit an average of 8 patients per month at the study site (The Ottawa Hospital Diabetes clinics) for study protocol performance.	12 months	Average number of patients recruited per month is determined by 60 patients (the target recruitment number) for each study intervention, divided by the number of months that it took to complete the recruitment.

Secondary Outcome Measures

Name	Time	Method
To assess the percentage hypoglycemia resolution for people living with type 2 diabetes based on their personalized choice of treatment and first recheck time.	12 months	Percentage hypoglycemia resolution with respect to grams of simple carbohydrates that participant chose, and first recheck time that participant preferred.
