Evidence at a glance
- Who can enter the study?
- Adults aged 18-65 with T1D already using closed-loop therapy; see registry for full criteria. 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
- The six-person study completed on 27 June 2026. No results have been posted; completion alone is not evidence that the algorithm worked safely or well.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: Other regions. 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 of the ten-hour visit functioning in closed-loop mode
- Failure rates of the algorithm, CGM, pump, user interface and remote monitoring
