About this study

Official title: Effect of Monitoring With Freestyle Libre 2 Glucose Sensor on Treatment Satisfaction in Patients With Type 2 Diabetes Mellitus: Exploratory Study in Patients Starting Monitoring

The FreeStyle Libre 2 system is a Flash glucose monitoring system that, after a scan, provides information on interstitial glucose for the last 8 hours in the form of a reading every 15 min. The system is approved for non-adjuvant use for therapeutic decision-making. The acceptability and effectiveness of the FSL is well documented in patients with type 1 and 2 diabetes mellitus (DM2). Most of the studies in patients with DM2 have been developed in patients with insulin treatment, either basal or with multiple doses.

For all these reasons, we proposed an exploratory study to evaluate satisfaction with treatment (main variable) in people with DM2 who start glucose monitoring in the Endocrinology Day Hospital context compared to patients who use capillary blood glucose monitoring. These are patients treated in a context of debut/acute decompensation/intercurrent pathology, who will not necessarily be using insulin treatment. The aim is to know if the use of FSL2 provides benefits of user satisfaction with the treatment, assessed with the Diabetes Treatment Satisfaction Questionnaire at the end of follow-up (mean score of all items); in this context.

Read the detailed description

When the doctor determines that the patient who has attended the Endocrinology and Nutrition Day Hospital needs to start glucose monitoring and goes to the nursing office, if he meets the inclusion criteria, he will be asked to participate in the study. After signing the informed consent, the control group (MGC) or intervention group (FSL2) will be randomised. The necessary therapeutic education for glucose monitoring will be carried out in parallel with the other necessary aspects of Diabetes Therapeutic Education.

Follow-up visits in both groups will take place 24-48 hours after the first visit, a week, 2 weeks, and 1, 2, and 3 months after the first visit. During visits, frequently according to usual clinical practice, by the nurse and/or doctor, therapeutic decisions will be made based on the monitoring system assigned to the patient.

What participants receive

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

  • FreeStyle Libre 2, flash glucose monitoringDevice

    Currently, at the Hospital de la Santa Creu i Sant Pau, when starting monitoring in people with DM2, capillary glycemia monitoring is used, following the therapeutic education protocols in basal insulinization in the debut of DM2 and in optimization of treatment, protocols that are also applied to similar cases.

    The intervention group (FreeStyle Libre 2) will be provided with the necessary material to carry out the monitoring via a glucose sensor. Satisfaction with treatment will be assessed at the final study visit.

Control group. Capilary glucose monitoringNo interventionThe patient randomized to the control group, capillary glucose monitoring, will be provided with the necessary material for six weeks (Free Style Optium glucometer, puncturer, Free Style Optium strips, lancets and record book) and the objectives, technique of analysis, recording and interpretation. The patient/carer will be asked to practice before leaving the office to ensure that they perform the technique correctly and effectively.

FreeStyle Libre 2ExperimentalThe patient randomized to the intervention group (FSL2) will be provided with the necessary material for six weeks (sensor, applicator and reader or mobile application (App)) and the objectives, analysis, recording and interpretation technique will be explained. The patient will be helped to register in the application and share the data with the hospital. The patient will carry out the first readings before leaving the consultation to ensure that they are carried out correctly.

What is being measured

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

  1. Satisfaction with the treatment

    Diabetes Treatment Satisfaction Questionnaire (DTSQ)

    Measured: 3 months

Secondary outcomes (7)
  1. Glucometrics

    In each group, assess the change in blood glucose according to your monitoring method

    Measured: 3 months

  2. The total number of visits

    • The total number of visits (in person, by telephone and asynchronous telematics, if applicable).

    Measured: 3 months

  3. Number of treatment

    The number of treatment changes applied to the patient.

    Measured: 3 months

  4. Duration of follow-up.

    Duration of follow-up. A maximum follow-up of 3 months is expected in both groups. However, earlier completion is expected if the patient is discharged, requires hospital admission or an exclusion criterion is made before performing V7

    Measured: 3 months

  5. HbA1c

    The hemoglobin A1c (HbA1c) test measures the amount of blood sugar (glucose) attached to your hemoglobin.

    Measured: Baseline and 3 months

  6. Perception of hiperglicemia

    The value of questions 3 of the DTSQ and % of local problems as security variables.

    Measured: 3 months

  7. Perception of hypoglicemia

    The value of questions 2 of the DTSQ and % of local problems as security variables.

    Measured: 3 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing FreeStyle Libre 2, flash glucose monitoring in people with Diabetes Mellitus, Type 2, run by Fundació Institut de Recerca de l'Hospital de la Santa Creu i Sant Pau at 1 site in Spain.

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 4 inclusion and 2 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 3 Oct 2024. 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 Spain. 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.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Satisfaction with the treatment (time frame: 3 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06624553, which also lists 12 linked publications.

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 3 Oct 2024.
