| Primary | Change from baseline in 2-hour AUC of C-peptide response to the Mixed Model Tolerance Test (MMTT) | C-peptide level is an indirect measure of pancreatic beta-cell function. The MMTT was performed after an overnight fast, at baseline | Month 12 | |
| Primary | Change from baseline in HbA1c | HbA1c measurement can be used as a diagnostic test for diabetes providing that stringent quality assurance tests are in place and assays are standardised to criteria aligned to the international reference values, and there are no conditions present which preclude its accurate measurement. An HbA1c of 6.5% is recommended as the cut point for diagnosing diabetes. A value of less than 6.5% does not exclude diabetes diagnosed using glucose tests. |
Month 12 | |
| Secondary | Change from baseline in 2-hour AUC of C-peptide response to the MMTT | C-peptide level is an indirect measure of pancreatic beta-cell function. The MMTT was performed after an overnight fast, at baseline | Months 6, 18 and 24 | |
| Secondary | Change in HbA1c from baseline | HbA1c measurement can be used as a diagnostic test for diabetes providing that stringent quality assurance tests are in place and assays are standardised to criteria aligned to the international reference values, and there are no conditions present which preclude its accurate measurement. An HbA1c of 6.5% is recommended as the cut point for diagnosing diabetes. A value of less than 6.5% does not exclude diabetes diagnosed using glucose tests. | Months 6, 18 and 24 | |
| Secondary | Time in range (TIR) by Continuous Glucose Monitoring (CGM) | Continuous glucose monitors (CGM) continually monitors glucose plasma levels through an external device that's attached to the body, and gives real-time updates.Time in range is the amount of time the patient spends in the target blood sugar (blood glucose) range-between 70 and 180 mg/dL for most people. The time in range method works with the individual CGM's data by looking at the amount of time blood sugar has been in target range and the times it has been high (hyperglycemia) or low (hypoglycemia). This data is helpful in finding out which types of foods and what activity level causes patient's blood sugar to rise and fall. |
Months 6, 12, 18, 24 | |
| Secondary | Proportion of patients with HbA1c <7% who did not experience severe hypoglycemic events during treatment | For the purpose of this study, a severe hypoglycemic event is defined as an event with one of the following symptoms: "memory loss, confusion, uncontrollable behavior, irrational behavior, unusual difficulty in awakening, suspected seizure, seizure, loss of consciousness, or visual symptoms", in which the subject was unable to treat him/herself and which was associated with either a blood glucose level <54mg/dL or prompt recovery after oral carbohydrate, i.e. glucose, or glucagon administration. | Months 6, 12, 18, 24 | |
| Secondary | Average (previous 3 days) daily insulin requirement (IU/kg/day) | For the purpose of this study, daily insulin is averaged over the previous 3 days.Insulin requirement (IU/kg/day averaged over the previous 3 days) was to be recorded to Months 6, 12, 18 and 24. Patients were admitted to intensive diabetes management, according to current ADA recommendation [2014]. Patients were instructed to self-monitor their glucose values at least 4 times a day and to report (glucose meter/log) outcome to the diabetes management team. Insulin intake was adjusted to target HbA1c levels of less than 7% and self-monitored (fingerstick): pre-prandial blood glucose of 70-130 mg/dL post-prandial blood glucose < 180 mg/dL bed-time blood glucose of 110-150 mg/dL |
Months 6, 12, 18, 24 | |
| Secondary | Proportion of patients with HbA1c <7% and daily insulin requirement <0.5 (IU/kg/day) | The sample size of the study is calculated on the "proportion of patients with a HbA1c < 7% and daily insulin requirement <0.50 IU/Kg/day", a post-hoc composite endpoint derived from data of the phase 2 trial (MEX0114), considering a larger effect size expected from the longer treatment length (one year versus 3 months). Follow-up is extended up to 24 months to evaluate the potential persistency of any glycemic benefit. | Months 6, 12, 18, 24 | |
| Secondary | Number of self-reported episodes of severe hypoglycemia | For the purpose of this study, a severe hypoglycemic event is defined as an event with one of the following symptoms: "memory loss, confusion, uncontrollable behavior, irrational behavior, unusual difficulty in awakening, suspected seizure, seizure, loss of consciousness, or visual symptoms", in which the subject was unable to treat him/herself and which was associated with either a blood glucose level <54mg/dL or prompt recovery after oral carbohydrate, i.e. glucose, or glucagon administration. | Months 6, 12, 18, 24 | |
| Secondary | Percentage of patients not requiring insulin therapy | This outcome aims to assess the % of patients who do not require an insulin therapy | Months 6, 12, 18, 24 | |
| Secondary | Estimated Glucose Disposal Rate (eGDR) | Estimated Glucose Disposal Rate (eGDR) is a marker for the Assessment of Insulin Resistance and a validated clinical tool for estimating insulin sensitivity in type 1 diabetes. | Months 6, 12, 18, 24 |
