What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
P0.3Device
Subjects will perform daily measurements on the IMD (Prototype 0.3) for 35 days.
| Study group | Role | What they receive |
|---|---|---|
| Protocol 1 | Experimental | The subjects enrolled in this protocol will dedicate 33 days of home-based measurement and two days for in-clinic measurements. For reference measurements, subjects will be equipped with a BG-meter (Contour Next One, Ascenia). Optical measurements are collected with the IMD. Each day of measurements consists of four sessions each comprising two capillary blood glucose measurement with a BG-meter and two IMD measurements. IMD measurements will be performed using the thenar of the right hand of the subject. Receives: Device: P0.3 |
What is being measured
The primary outcome is the main question the study is designed to answer.
Generation of predictive algorithms for determining blood glucose levels
Collected spectral raman data will found the development of predictive algorithms for glucose determination.
Measured: 12 months
Validation of predictive algorithms for determining blood glucose levels
Performance of predictive models will be evaluated using the consensus error grid.Unified Performance (ISUP), Mean Absolute Relative Difference (MARD) and Consensus Error Grid (CEG) distribution.
Measured: 12 months
Secondary outcomes (2)
Risk/benefit analysis
Support of a favorable risk/benefit analysis based on reported Adverse Device Effects and Serious Adverse Device Effects.
Measured: 12 months
Number of encountered Device Deficiencies
Evaluation of Device Deficiencies with respect to identity, quality, durability or reliability, including malfunctions, use errors and inadequate labeling.
Measured: 12 months

Questions about this trial
What is this clinical trial studying?
A study testing P0.3 in people with Diabetes Mellitus, run by RSP Systems A/S at 1 site in Denmark.
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 8 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: finished, as of the sponsor's last update on 8 Oct 2020. 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 Denmark. 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Generation of predictive algorithms for determining blood glucose levels (time frame: 12 months). 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 8 Oct 2020; AzTrials last refreshed its copy on 8 Nov 2026.
