About this study

Official title: Effect of Dapagliflozin on Blood Pressure Variability in Patients With Prediabetes and Prehypertension Without Pharmacological Treatment

Prediabetes is defined as an intermediate metabolic state that leads to the development of type 2 diabetes mellitus (DM2) and the prehypertension is a category assigned to identify patients who are at risk of developing hypertension (AH), in both pathologies the abnormalities in the variation of blood pressure (BP) has been related to organ damage, its evaluation is performed by ambulatory blood pressure monitoring (ABPM).

Dapagliflozin is a selective and reversible inhibitor of the sodium-glucose co-transporter type 2 (SGLT-2), which reduces renal reabsorption of glucose and promotes the excretion of glucose through the urine, in the way that glucose blood. Another reported effects is the decrease on BP, so it would be interesting to evaluate this effects in patients with prediabetes and prehypertension, as a potential therapy to treat disorders and to prevent progression to DM2 and Hypertension, respectively.

The aim of this study is to evaluate the effect of Dapagliflozin on variability of blood pressure in patients with prediabetes and prehypertension without pharmacological treatment.

The investigators hypothesis is that the administration of dapagliflozin decreases variability of blood pressure in patients with prediabetes and prehypertension without pharmacological treatment.

Read the detailed description

A randomized, double-blind, placebo-controlled clinical trial in 30 patients with a diagnosis of prediabetes and prehypertension without treatment.

They will be assigned randomly two groups of 15 patients each to receive 10 mg of Dapagliflozin (Forxiga, Astra Zeneca) or placebo, one per day before breakfast during 12 weeks.

There will be calculated body mass index (BMI) and blood pressure variability. This protocol it's already approved by the local ethics committee and written informed consent it's going to be obtained from all volunteers.

Statistical analysis will be presented through measures of central tendency and dispersion, average and deviation standard for quantitative variables; frequencies and percentages for variable qualitative. Qualitative variables will be analyzed by X2/ exact fisher test, will be used for differences inter-group Mann-Whitney U Test and coefficient of variation, Wilcoxon Test and index of variability for the within-groups differences. It will be considered statistical significance p ≤0.05.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Dapagliflozin in people with PreDiabetes and Prehypertension, run by University of Guadalajara at 1 site in Mexico.

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 10 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 9 Nov 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 Mexico. 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 19 Oct 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

24-hours Systolic Blood Pressure at Week 12 (time frame: Week 12). The study lists 19 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 9 Nov 2020.
