Could a smart patch help older diabetics ditch the finger pricks?
NCT ID NCT07007676
First seen Jun 27, 2026 · Last updated Sep 09, 2026 · Updated 2 times
Summary
This study is testing whether a continuous glucose monitor (CGM) can help older adults with type 2 diabetes who do not use insulin achieve better blood sugar control. Participants will either wear a CGM every two months or use standard finger-stick monitoring for six months. The main goal is to see if CGM leads to a greater drop in HbA1c levels.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- continuous glucose monitoring device
- What this could lead to
- If successful, this could show that continuous glucose monitors help older adults with type 2 diabetes manage their blood sugar better without needing insulin.
- What could go wrong
- This is a small, early-stage trial with only 148 participants, and the benefit may not be large enough to change standard care. The device may also be less accurate or harder to use in older adults.

Inclusion Criteria: * Age ≥ 60 years at the time of screening; * Diagnosed with type 2 diabetes mellitus; * Treated with two or more oral antidiabetic drugs with a stable medication regimen (medication classes) during the 3 months prior to entry; * Suboptimal glycemic control, defined as HbA1c ≥ 7.5% and ≤ 10% at screening or within 30 days prior to screening visit; * Has a smart phone compatible with CGM and BGM systems; * Willing and able to provide written informed consent; * At least 240 hours (10 out of 14 days) of sensor glucose data from the blinded CGM pre-randomization phase. Exclusion Criteria: * Use of insulin or Glucagon-Like Peptide-1 (GLP-1) receptor agonists within 3 months prior to screening; * Use of any CGM device within 3 months prior to screening; * Participants were unable to tolerate tape adhesive around sensor placement area, or with medically documented allergy towards the adhesive (glue) of plasters, or with serious skin diseases (e.g. psoriasis vulgaris, bacterial skin diseases) around sensor placement area; * Considered unsuitable for participation by the investigators, including but not limited to individuals with dementia, psychiatric disorders, extreme visual or hearing impairment that would impair ability to use real-time CGM assessed; * Planned surgery or other procedures within the next 6 months that may interfere with scheduled follow-up visits; * Current or anticipated acute uses of glucocorticoids (oral, injectable, or IV), that will affect glycemic control; * Estimated glomerular filtration rate (eGFR) \< 30 ml/min/1.73m2; * Participation in any other clinical trial within 3 month prior to screening, or concurrently enrolled, or planning to participate in another trial during the study period.
