About this study
The study is to evaluate the accuracy and safety of a novel real-time CGM system among adult patients with type 1 diabetes mellitus with respect to YSI reference venous plasma sample measurements.
Read the detailed description
The study is to evaluate the accuracy and safety of a novel real-time CGM system among adult patients with type 1 diabetes mellitus with respect to YSI reference venous plasma sample measurements. No less than 42 patients will be enrolled. Each patient will wear two sensors. Interstitial glucose readings from each sensor will be obtained immediatedly following each venous blood sample test. Each participant will make 4 visits to the clinical study site, including the screening visit.
- Conditions
- Type1diabetes
- Being tested
- GS3 CGM
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
GS3 CGMDevice
Wearing CGM for a consecutive 14 days
| Study group | Role | What they receive |
|---|---|---|
| Adult patients with T1DM or T2DM | Other | Not described Receives: Device: GS3 CGM |
What is being measured
The primary outcome is the main question the study is designed to answer.
System performance
The CGM system performance will be assessed by comparing to the Yellow Springs Instrument comparator venous plasma measurements
Measured: 14 days
System-related Safety
The CGM system will be characterized by adverse device effects experienced by the study participants
Measured: 14 days

Questions about this trial
What is this clinical trial studying?
A study testing GS3 CGM in people with Type1diabetes, run by Henan University of Science and Technology at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 29 May 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Peng Liu (0379-64811993, peng.liu87@outlook.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
System performance (time frame: 14 days). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 May 2026.
