Primary
| Measure | Time frame |
|---|---|
| Changes in time in range (TIR) by continuous glucose monitoring (CGM) for one week before and during trehalose administration Change (difference) A = 1 week of trehalose administration period - 1 week of previous observation period | — |
Secondary
| Measure | Time frame |
|---|---|
| Difference between before and after TIR at 1 week post-treatment and at 1 week of the pre-treatment period Change (difference) B = 1 week post-treatment - 1 week pre-treatment Difference in TIR between 1 week post-treatment and 1 week during the trehalose treatment period Change (difference) C = 1 week post-treatment - 1 week of trehalose administration period Before and after TIR of 1 week post-trehalose administration period and 1 week preobservation period Percentage change A = Change (difference) A / 1 week pre-treatment period * 100 Change in time above range (TAR) by CGM (difference A and rate A) Change in Time below range (TBR) by CGM (Difference A and Rate A) Change in mean blood glucose by CGM (difference A and rate A) Change in C-peptide (Difference A and Rate A) Change in HbA1c, glycoalbumin, 1,5-AG (difference A and rate A) Change in total daily dose of insulin (difference A and rate A) TIR before and after 1 week post-dose and 1 week pre-observation period Rate of change B = change (difference) B / 1-week pre-treatment period * 100 Change in TAR by CGM (difference B and rate B) Change in TBR by CGM (difference B and rate B) Change in mean blood glucose by CGM (difference B and rate B) Change in C-peptide (Difference B and Percentage B) Change in HbA1c, glycoalbumin, and 1,5-AG (difference B and rate B) Change in total daily dose of insulin (difference B and rate B) TIR before and after 1 week post-dose and 1 week during trehalose administration Rate of change C = change (difference) C / 1 week of trehalose administration period * 100 Change in TAR by CGM (difference C and rate C) Change in TBR by CGM (difference C and rate C) Change in mean blood glucose by CGM (difference C and rate C) Change in C-peptide (difference C and rate C) Change in HbA1c, glycoalbumin, and 1,5-AG (difference C and rate C) Change in total daily dose of insulin (difference C and rate C) * Time above range (TAR) is the percentage of time that blood glucos | — |
