About this study

This pivotal multicenter study has been launched to collect spectral Raman data paired with validated glucose reference values in diabetic patients.

Read the detailed description

Participants will be enrolled at six different sites in four different countries. All participants will undergo identical procedures, which include four steps: Baseline visit (1 day), calibration period (25 days), validation period (23 days) and a close-out visit (1 day) with a total duration of 50 days.

The calibration period consists of 23 home-based days and two in-clinic days. At the two in-clinic days, measurement sessions are performed every 30 minutes. A measurement session consists of two reference measurements (Contour Next One) and three measurements on the Investigational Medical Device. The glucose level of the participants is manipulated by administration of a glucose rich drink. At home-based days, the subject must perform four measurement sessions a day. During the validation period, participants perform up to four home-based measurement sessions a day.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Prototype 0.5Device

    Also called P0.5

    Investigational Medical Device collecting spectral Raman data non-invasively from tissue

Study groups in NCT04031300
Study groupRoleWhat they receive
RSP-20ExperimentalSubjects will perform daily measurements on the IMD (Prototype 0.5) in addition to capillary reference measurements for 48 days.
Receives: Device: Prototype 0.5

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Measurement accuracy

    Accuracy of measurements performed on the IMD will be evaluated by data from subjects. Data will be analyzed by Mean Absolute Relative Difference (MARD).

    Measured: 6 months

  2. Safety evaluation: paucity of adverse events

    Safety of the IMD will be evaluated in a descriptive manner by the paucity of adverse events reported during the clinical study

    Measured: 6 months

Secondary outcomes (2)
  1. Device deficiencies

    Description of device deficiencies will be listed. Deficiencies will be reported during the clinical study.

    Measured: Up to 6 months

  2. Device usability

    The use of the device will be evaluated by means of questionnaires. The subjects are asked if they encountered any problems during measurements, and if so, to elaborate the problems encountered.

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

A study testing Prototype 0.5 in people with Diabetes Mellitus, run by RSP Systems A/S at 6 sites in 4 countries.

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 14 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: withdrawn, as of the sponsor's last update on 21 Nov 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in Denmark, Sweden, Germany, United Kingdom. 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 was withdrawn before enrolling participants, so there are no results.

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?

Measurement accuracy (time frame: 6 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 21 Nov 2023.
