Optimizing Basal-Bolus Therapy in T2D—A Randomized Controlled Trial Comparing Bolus Insulin Delivery Using an Insulin Patch vs. an Insulin Pen

This multicenter RCT compared clinical, subject-reported, and safety outcomes in T2D subjects on basal insulin (A1C 7.5-11%) initiating mealtime insulin with a wearable bolus insulin delivery patch (Patch, Calibra Medical) vs. an insulin pen (Pen, NovoLog FlexPen®). The Patch was applied at least every 3 days and delivered subcutaneous bolus insulin in 2-U increments per manual click. T2D adults (N=278, age: 59.2 y, duration: 15 y), were randomized to Patch (n=139) or Pen (n=139). Baseline glargine dose was divided 1:1, basal:bolus. Using a pattern-control logbook, subjects adjusted basal and bolus insulin weekly based on fasting and pre-meal glucose targets. Change in A1C (%) from baseline to Week 24 (primary endpoint) for Patch was noninferior (p There were no significant differences in adverse events, including hypoglycemia (3 severe episodes/group). There were significantly greater improvements in subject-reported outcomes for Patch vs. Pen. In conclusion, bolus insulin delivered by Patch or Pen along with an algorithm-based weekly insulin dose titration significantly improved A1C levels in subjects with T2D, with improved patient experience and a preference for Patch.
