Evaluation of Empagliflozin vs Standard Care in Veterans With Prediabetes (PREVNT)

November 18, 2025 updated by: Beth Greck, Charles George VA Medical Center

Sodium-glucose Transporter 2 Inhibitor Use in Pre-diabetes: Initial Evaluation in Veterans

Prediabetes effects 96 million people 18 years of age or older. It is important to identify treatment options to slow or prevent progression to diabetes. It is also critical to assess the potential of medications like sodium glucose transporter 2 inhibitors to reduce the risk of cardiovascular events and kidney complications, both common and costly complications of diabetes. This is a 12-week, open-label pilot feasibility study assessing the use of empagliflozin in prediabetes.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult

Accepts Healthy Volunteers

No

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Active Comparator: Standard Care
Participants in this arm will receive lifestyle education to manage pre-diabetes as well as the monitoring of HbA1c, kidney function, weight, and blood pressure.
Other: Lifestyle education
This intervention is considered standard care for prediabetes.
Experimental: Standard Care plus empagliflozin
Participants in this arm will receive lifestyle education to manage pre-diabetes as well as the monitoring of HbA1c, kidney function, weight, and blood pressure. They will also receive empagliflozin 10mg daily.
Other: Lifestyle education
This intervention is considered standard care for prediabetes.
Drug: Empagliflozin 10mg daily
This intervention will assess recruitment and retention (feasibility trial).

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Recruitment
Time Frame: 12 weeks
Number of participants screened during study period Number of participants randomized during study period Number of participants enrolled during study period
12 weeks
Retention
Time Frame: 12 weeks
Number of participants enrolled who complete the study Number of participants enrolled who do not complete the study and reason for not completing the study
12 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Adverse Events
Time Frame: 12 weeks
Total number of adverse events occurring among enrolled participants in each group as well as type of adverse event. At conclusion of study will report percent of adverse events reported with each group, i.e. number of participants in control group reporting adverse event/total number of participants enrolled in control group.
12 weeks
HbA1c (%)
Time Frame: 12 weeks
HbA1c measured at baseline (visit 1) and 12 weeks (visit 3) will be reported as aggregate data for change from baseline to visit 3 for control group and exposure group.
12 weeks
Renal function (ml/min)
Time Frame: Every visit (baseline (T), T+2-4 weeks, T+12 weeks)
estimated GFR (eGFR) (ml/min) will be collected at each study visit and reported as aggregate data for change from baseline to visit 2 and visit 3 for control group and exposure group.

Weight (kg)
Time Frame: Every visit (baseline (T), T+2-4 weeks, T+12 weeks)
