151-OR: Technosphere Insulin Provides Better Early Postprandial Glucose Control than Subcutaneous Rapid-Acting Analog

Abstract

In a recent study (STAT, NCT03143816), patients with type 1 diabetes mellitus (T1DM) treated with Technosphere Insulin (TI) demonstrated better early postprandial glucose (PPG) control than those on subcutaneous (SC) insulin aspart. The average daily dose of TI in patients who took TI as directed in the protocol was twice that of aspart (40.5 vs. 20.6 units). Despite the higher dose, the TI group experienced less time in hypoglycemia than the aspart group. These results prompted a retrospective analysis of mixed-meal tolerance tests (MMTTs) conducted in T1DM to further evaluate the 2:1 dosing ratio. In study MKC-TI-009 (NCT00308308), patients with T1DM underwent 1 to 3 MMTTs. A total of 1326 PPG profiles were evaluable: 674 MMTTs from 261 patients on SC aspart and 652 MMTTs from 264 patients on TI. On average, the area under the PPG excursion curve (PPGE AUC) decreased with increasing dose, and the mean (SE) ratio of the aspart slope to the TI slope was 2.1 (0.3), consistent with the results of STAT. This was confirmed when doses of TI 8, 16, and 24 units were compared with mean (SE) aspart doses of 4 (1), 8 (1), and 12 (1) units, respectively (Figure). The PPGE curves confirm the earlier onset and shorter duration of TI, while the tendency to drop below baseline in the late postprandial period reflects the longer duration of action of SC aspart. The timing of hypoglycemia (levels 1 and 2) follows the pattern of PPGEs. Disclosure M.L. Grant: Employee; Self; MannKind Corporation. Stock/Shareholder; Self; MannKind Corporation. F.
