Is this trial a fit for you?

Likely a good fit

Adults aged 18–65 with type 1 diabetes on intensive insulin therapy (MDI or insulin pump), willing to wear multiple CGM sensors, perform frequent fingersticks, and attend four clinic visits during the 16-day period are ideal candidates.

Probably not a fit

Patients with severe skin conditions at the sensor site, known allergic contact dermatitis to medical adhesives, a recent history of severe hypoglycemia, or inability to perform frequent fingerstick testing are unlikely to benefit or be eligible.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Adults with type 1 diabetes will wear two CareSens Air 3 sensors and one Libre 3 Plus for 16 days while continuing their usual insulin regimen and without access to CareSens Air 3 readings. Participants will perform at least eight capillary blood glucose checks per day using SMBG and will attend four clinic visits for controlled reference measurements, including induced low and high glucose conditions. The Libre 3 Plus and capillary blood samples will serve as reference comparators to quantify the accuracy and precision of the CareSens Air 3. The trial is an open-label, single-arm pilot designed to generate performance data for the device.

Why it matters

Potential benefit: If successful, the CareSens Air 3 could provide reliable continuous glucose readings that help people with type 1 diabetes manage insulin dosing more safely and effectively.

How similar studies have gone: Multiple prior studies have validated other CGM systems (for example FreeStyle Libre and Dexcom) using similar head-to-head and capillary reference methods, though the CareSens Air 3 itself is being newly tested here.

Who can join: the full rules

Show full inclusion / exclusion criteria 
Inclusion Criteria:

* Adults who are 18-65 years of age, inclusive
* Patients with type 1 diabetes who use intensive insulin therapy (multiple daily injections (MDI) or continuous subcutaneous insulin infusion (CSII) including users of systems with continuous glucose monitoring (CGM) driven automatic adjustment of insulin doses for at least 3 months
* Patients who voluntarily decide to participate in the study and provide written informed consent

Exclusion Criteria:

* The following abnormal skin or skin diseases or skin alterations at the CGM sensor attachment or insertion site: Severe psoriasis, recent burn injury or severe sunburn, severe eczema, severe scar, extensive tattoo, dermatitis herpetiformis, severe rash, Staphylococcus aureus infection.

* Patients with anemia (hemoglobin below normal range).
* Patients scheduled for X-ray, MRI, CT or diathermy during the study.
* Pregnant or lactating women or those who plan to become pregnant or do not agree to use an adequate method of contraception during the study.
* Patients who are currently participating or participated within 2 weeks prior to screening in another study or plan to participate in another study that in the opinion of the investigator would affect the safety of the study participant or the study result.
* Patients unwilling to abstain from ingesting the foodstuffs listed in Appendix 3 in excess of the allowed amounts.
* Patients with cognitive impairment or who are not suitable for this study or may be at increased risk associated with study participation in the opinion of the investigator.
* Wearing of a pace maker or other comparable medical devices.
* HbA1c \>9.5%.
