Popis: INI has emerged as a potential treatment for T2DM-related functional decline and is safe in adults without T2DM. However, INI safety in T2DM-IDDM is unknown. We aimed to demonstrate safety of long-term INI use in T2DM-IDDM MemAID participants. We screened 86 participants with T2DM-IDDM, 14 were randomized (9 INI/5 Placebo), 9 started treatment (5 INI [60±14 years, 2 Female]; 4 Placebo [68±2 years, 1 Female]). Of those, 2-INI and 3-Placebo participants completed 24 weeks of treatment and 24 weeks of follow-up. Participants underwent one week of continuous glucose monitoring (CGM)(Medtronic IPro2) at baseline and after INI (Novolin® R ) or placebo initiation. HbA1c, fasting plasma and capillary glucose, and insulin were measured throughout the study. Insulin levels were unchanged across the study. In 2 INI-treated participants, HbA1c, fasting plasma and capillary glucose declined from baseline, but the average values were similar during treatment and follow up, and comparable to 3 placebo-treated participants. Both INI-treated participants had adjustments of IDDM regimens. Capillary glucose did not decline 2 hours after INI administration, and there were no interactions between INI and subcutaneous insulin. There were no INI-related serious adverse events. Of 13 hypoglycemia (HG) episodes across the study, 2 asymptomatic level-1 HG (15.4%) occurred in INI group and 7 (53.8%) in placebo group. There were 2 asymptomatic level-2 HG (15.4%) in both INI and placebo groups. INI therapy was not associated with serious adverse events or HG in older participants with T2DM-IDDM. This study may pave the way towards future larger studies evaluating the safety of concomitant administration of INI and subcutaneous insulin (NCT02415556). Disclosure L. Aponte becerra: None. B.
