This multicenter RCT compared efficacy, safety, and User-/HCP-reported outcomes for adults with T2D (Users, A1C: 7.5-11%) on basal insulin initiating mealtime insulin with a wearable bolus insulin delivery patch (Patch, Calibra Medical, n=139) vs. an insulin pen (Pen, NovoLog FlexPen®, n=139). The Patch was applied at least every 3 days and delivered subcutaneous bolus insulin in 2-U increments per manual click.

Study duration was 48 weeks with cross-over at Week 44; 88% (Patch) and 86% (Pen) of Users completed Week 24 assessments; 77% and 76% completed Week 48 assessments. Treating HCPs (N=89) rated their experience with Patch at Week 24.

Change in A1C (%) from baseline to Week 24 (primary endpoint) showed noninferiority of Patch vs. Pen (p<.0001). Change in User satisfaction (measured by the Insulin Delivery System Rating Questionnaire) at Week 24 favored Patch over Pen for all measures; comparisons for convenience and overall satisfaction were significant (p<.01). Change in User quality of life (measured by the Diabetes-Specific Quality of Life Questionnaire) at Week 24 favored Patch over Pen for 6/7 measures; comparisons for daily functions and diet restrictions were significant (p<.05). Comparisons of User experience ratings at Week 24 favored Patch over Pen for all 11 items; 7 of those showed a significant difference (p<.01). At Week 48, User preferences for Patch over Pen among those who had used Patch for 44 weeks ranged from 72% to 82%; 69% wanted to change from Pen to Patch. Results were similar but less pronounced for those who had used Patch for 4 weeks.

HCP questionnaire ratings for clinical appropriateness of Patch at Week 24 ranged from 67% to 85% in favor. Additionally, 74% rated training for Patch use as “easy” and 89% reported that it took ≤30 minutes; 91% of HCPs preferred Patch over Pen for initiating mealtime insulin.

These results suggest that Patch is a viable alternative to Pen for mealtime insulin; both Users and HCPs preferred Patch to Pen.
