NOMAD: unannounced meals on open-source vs commercial AID

What this study tests

A not-yet-recruiting randomized crossover study comparing open-source AID (Loop, AndroidAPS or OpenAPS) with commercial AID (Control-IQ or Omnipod 5) during standardized unannounced meals in adults already using open-source AID.

Evidence at a glance

Who can enter the study?
Adults in Canada or the US with T1D for at least one year who have used open-source AID with Dexcom G6 or G7 for at least two weeks. Registered eligibility ↗Enrollment criteria describe who may enter. They do not establish who was analyzed or the denominator for a reported result.
Reported benefit and results
No results. Not yet recruiting; estimated n=33; estimated start 1 October 2026. First posted 11 August 2026.Read the result sources and their limitations →
Important harms
Read the reported results, safety discussion and original sources. A separate harms summary is not available; this does not establish safety.
Research access and approval
Study regions: Canada. A trial listing does not establish product approval or current recruitment at a particular site. Check the study’s current entry requirements.
What remains uncertain?
Read the full discussion and original sources for study limitations. Planned endpoints and completion dates are not results.

Research status alone does not establish approval, clinical benefit or local availability.

Primary endpoints

  • Percentage time in 70–180 mg/dL (3.9–10.0 mmol/L) during the 4 hours after standardized unannounced meals

The full picture

NOMAD asks a practical question: when meals are not announced, does an experienced open-source loop hold post-meal glucose as well as Control-IQ or Omnipod 5? It is not a pivotal of a new pump. Until it starts, it is a registered design, not a result.
