Initiation and Gradual Intensification of Premixed Insulin Lispro Therapy Versus Basal ± Mealtime Insulin in Patients With Type 2 Diabetes Eating Light Breakfasts
Bibliographic record
Abstract
OBJECTIVE: We compared two strategies initiating and intensifying insulin treatment and tested for noninferiority of premixed insulin to basal ± mealtime insulin analog in patients eating light breakfasts. RESEARCH DESIGN AND METHODS: This randomized, open-label, 48-week study compared two algorithms. Up to three injections of insulin lispro mix 25 and/or insulin lispro mix 50 (premix; premixed insulin lispro) or basal insulin glargine plus up to three injections of insulin lispro (basal+; glargine + insulin lispro) were used in type 2 diabetic patients uncontrolled with oral antihyperglycemic medication and consuming <15% daily calories at breakfast. The hypothesis was to test noninferiority of premix to basal+ for glycemic control measured by HbA1c after 48 weeks, assessed using ANCOVA with a 0.4% margin. RESULTS: Patients (n = 344; 176 [51%] females; mean [SD] age 54.3 [8.8] years; BMI 29.4 [4.6] kg/m(2); baseline HbA1c 9.02 [0.97]%) were randomized to premix (n = 171) or basal+ (n = 173). In the per-protocol analysis (n = 230), least squares means (95% CI) end point HbA1c were 7.40% (7.15-7.65) and 7.55% (7.27-7.82) in respective arms. Between-treatment difference was -0.14% (-0.42 to 0.13), with noninferiority met. Significantly more patients in premix achieved HbA1c targets of <7.0% compared with basal+ (48.2 vs. 36.2%; P = 0.024). Self-monitored blood glucose profiles, body weight changes, total insulin doses, and overall hypoglycemia (65 vs. 60%) were similar in premix and basal+ (P = 0.494), except nocturnal episodes (34.3 vs. 23.7%; P = 0.018) were more common in premix. CONCLUSIONS: Both intensive insulin strategies improved glycemic control; however, final HbA1c levels were seen above those achieved in previous treat-to-target trials, likely due to the inadequate insulin titrations and probably due to the complexity of tested insulin regimens. A higher percentage of patients achieved target HbA1c <7% with multiple premixed insulins, but this treatment resulted in more nocturnal hypoglycemia than a basal-bolus regimen.

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.
