Tubeless AID system improves glycemic outcomes in type 1 diabetes

Last updated July 12, 2026

Key finding

TIR during the trial was 4.2h/day higher in the intervention compared with the control group (mean difference 17.5% [95% CI 14.0%, 21.1%]; P < 0.0001)

This study evaluated the efficacy and safety of the Tubeless Omnipod 5 automated insulin delivery system compared to traditional pump therapy with continuous glucose monitoring in adults with Type 1 diabetes.

Plain-language summary

What this paper says

A plain-language read of the study’s main message and where it applies.

Study focus

This study evaluated the efficacy and safety of the Tubeless Omnipod 5 automated insulin delivery system compared to traditional pump therapy with continuous glucose monitoring in adults with Type 1 diabetes.

Clinical relevance

These findings are significant for clinicians and patients as they suggest that the Tubeless Omnipod 5 may offer a more effective and safer option for managing blood glucose levels in adults with Type 1 diabetes, potentially leading to better long-term health outcomes.

Keep in mind

The study's sample size may limit the generalizability of the findings. The trial duration may not capture long-term effects of the interventions. Participants were selected based on specific criteria, which may not represent the broader population.

Main Effects

The intervention group had 4.2 hours/day more time in range (TIR 70-180 mg/dL) compared to the control group.

The intervention group showed a greater reduction in HbA1c by 1.24% from baseline.

The intervention group experienced significantly lower time <70 mg/dL and >180 mg/dL by 0.57% and 16.8%, respectively.

No diabetes-related ketoacidosis or severe hypoglycemia events occurred in the intervention group.
