Trial summary

The study is a randomized cross-over pilot study. The research hypothesis is that the diet high in SDS content (H-SDS) will lower the daylong glycemic response and improve the glycemic control in patients with type 2 diabetes (T2D) compared to the diet low in SDS content (L-SDS).

About this study

Official title: A Pilot Randomized Controlled Trial Evaluating the Effect of Two Diets With Different Starch Digestibility Profiles on Daily Glycemic Profile Measured by Continuous Glucose Monitoring System (CGMS), in Type 2 Diabetic Patients

The study is a randomized cross-over pilot study. The research hypothesis is that the diet high in SDS content (H-SDS) will lower the daylong glycemic response and improve the glycemic control in patients with type 2 diabetes (T2D) compared to the diet low in SDS content (L-SDS).

Read the detailed description

The study is a randomized cross-over pilot study. The research hypothesis is that the diet high in SDS content (H-SDS) will lower the daylong glycemic response and improve the glycemic control in patients with type 2 diabetes (T2D) compared to the diet low in SDS content (L-SDS).

8 patients with type 2 diabetic patients will be recruited.

Subjets will have 5 visits:

The selection visit (V1) is required to check whether the patients fulfill inclusion and exclusion criteria for the study.

The visit V2 will include randomization, medical check-up and a dietary interview (LogBook supply with explanations for filling and dietary advice cards for the 1st week of diet). The nurse will insert the CGMS and the patient will receive detailed instructions on wearing the sensor and recorder. The patient will leave the research center with a glucometer, the starchy foods and cereal products adapted for its first week of diet and the associated cooking instruction sheets and menus given by the dietician.

During each day of the first experimental diet period, the patient will take at least four blood glucometer readings per day, and will consume the food products according to a menu plan and the cooking instruction sheets given by the dietician, and fill a dietary record.

After 6 days +/- 1 day, the patient will return to the center (Visit V3) to remove the CGMS, bring back the glucometer and the follow-up LogBook. A Medical check-up will also be performed. Compliance will be assessed using the dietary record of the follow-up LogBook and the return of the uneaten products (weighting). A feedback questionnaire will be completed by each patient to have a global assessment of the diet and to evaluate the feasibility of this type of diet over longer periods.

The wash-out period will then last 2 weeks +/- 3 days. Then a new sequence will start. The visit V4 will be similar to visit V2 with: installation of the CGMS, provision of the LogBook and diet specific information for the second period. The glucometer and starchy foods and cereal products will be supplied to the patients.

During each day of this second diet period, patients will be required to consume starchy foods and cereal products according to a menu plan and cooking instructions provided by the dietician, and fill a dietary record. The patient will realize 4 capillary blood glucose control and will fill the information required in the LogBook.

Finally, Visit V5 will be the last visit. It will include, like for visit V3: removal of CGMS, return of glucometer and follow-up LogBook and a medical check-up . Compliance will be assessed using the dietary record of the follow-up LogBook and the return of the uneaten products (weighting). A feedback questionnaire will be completed by patients.

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 17 inclusion and 31 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 27 May 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 France. 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. Some participants in this study may receive a placebo. 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?

Mean postprandial incremental Area Under the Curve (iAUC), measured by CGMS (time frame: minimum 2h to maximum 6h postprandial periods and average value of minimum 3 days to a maximum of 6 days of CGMS record). 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 NCT03289494, which also lists 1 linked publication.

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 27 May 2020.
