Safety and Effectiveness of an Investigational Insulin Delivery Device Providing Basal/Bolus Therapy with Rapid-Acting or Regular Human Insulin in Adults with Type 2 Diabetes
Bibliographic record
Abstract
Background: This study undertook to assess usability, 24-h glycemic profiles, and safety of an investigational basal/bolus insulin delivery device (IDD) providing rapid-acting or regular human insulin (RHI) for people with type 2 diabetes (T2D) transitioning from multiple daily insulin injections (MDIs). Methods: This prospective, single-center, open-label two-period study enrolled adults with T2D and glycated hemoglobin (HbA1c) 7%–11% (53–97 mmol/M). Participants continued the usual MDI therapy during a 2- to 3-day in-clinic MDI period and then within 7 days were switched to the IDD, using current insulin dose, for a 6-day in-clinic IDD period, with blinded continuous glucose monitoring throughout the in-clinic periods. Results: We enrolled 21 participants (mean ± standard deviation age 57 ± 8 years; HbA1c 8.2% ± 0.9% [66 ± 9.8 mmol/M]) using U-100 insulin lispro ( n = 11) or who switched to U-100 RHI ( n = 10). Glycemic measures improved from the MDI to IDD period, including fasting blood glucose (BG), 141.2 ± 38.3 mg/dL (7.8 ± 2.1 mmol/L) versus 121.2 ± 35.0 mg/dL (6.7 ± 1.9 mmol/L; P = 0.002), respectively; 24-h mean BG, 137.0 ± 20.5 mg/dL (7.6 ± 1.1 mmol/L) versus 125.0 ± 16.5 mg/dL (6.9 ± 0.9 mmol/L; P = 0.004); and time in range (at 70–180 mg/dL; 3.9–10 mmol/L), 81.0% ± 14.4% versus 87.5% ± 10.6% ( P = 0.008). No significant differences between MDIs and IDD use were recorded for time <70 mg/dL (1.6% ± 2.7% vs. 3.1% ± 2.7%, P = 0.08), CV%, or mean of daily differences. Mean amplitude of glycemic excursions was significantly lower with the IDD ( P = 0.011). There were no significant differences between insulin lispro and RHI for any glycemic measure. No serious adverse events were recorded. Conclusions: In the context of this exploratory study, the IDD was safe and effective to administer insulin lispro and RHI for adults with T2D.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
