Study summary

In this study the effects of the Inhibition of the Sodium-Glucose Linked Transporter 2 in the kidney with empagliflozin compared to hydrochlorothiazide on blood pressure and on central sympathic nervous activity will be examined.

Read the detailed description

The drug empagliflozin is a selective oral inhibitor of the sodium-glucose co-transporter 2 (SGLT-2) in the kidney.On the market empagliflozin is approved for the treatment of type 2 Diabetes. The mechanism of action can be described as follows: SGLT-2 is responsible for 90% of the reabsorption of Glucose in the kidney. If this Transport System is inhibited the secretion of glucose via the urine is increased. Therefore the blood glucose concentration will be lowered.

It has been noted that the SGLT-2 drugs are lowering the blood pressure as well, but the specific characteristics of the durg leading to this effect have not been examined in adequate clinical trial up to now.

To evaluate the central sympathic nervous activity a microneurography will be performed in this study; this examination will provide Information if empagliflozin dose decrease the sympathic nervous activity. If this is the case new effects of empagliflozin have to be discussed, Otherwise it can be assumed that the blood pressure decrease is a result of an increase of urine volume. In this case the sympathic activity should be increased.

This study will be performed in parallel groups who will receive a double-blind, randomised treatment, either empagliflozin or hydrochlorothiazide. The hypothesis that empagliflozin - in contrast to hydrochlorthiazide - does not increase the sympathic nervous activity in obese, hypertensive subjects with type 2 Diabetes treated with metformin will be tested.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • women and men >= 50 and \<= 80 years of age
  • type 2 diabetes mellitus for >=2 years
  • only metformin monotherapy is allowed; metformin dose must have been stable for >=12 weeks

Exclusion criteria

Exclusion Criteria:

  • previous empagliflozin treatment within the last 3 months
  • heart failure II - IV
  • subjects who have received any medicinal product or have used any investigational medical device within 30 days prior to the screening visit, or who are actively participating in any investigational medicinal product or medical device trial, or who are scheduled for any such trial during the course of the trial.
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

NYHA class (heart failure)

The New York Heart Association’s four classes of how much heart failure limits physical activity.

I
No limits: ordinary activity causes no undue tiredness or breathlessness.
II
Slight limits: comfortable at rest, ordinary activity causes symptoms.
III
Marked limits: comfortable at rest, less than ordinary activity causes symptoms.
IV
Symptoms even at rest; any activity makes them worse.

Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

What researchers measure

Primary outcomes

  1. Blood Pressure reduction

    Blood pressure reduction with empagliflozin treatment is associated with lesser increase in sympathetic nerve traffic when compared to Hydrochlorothiazide treatment

    Time frame: 6 weeks

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Dec 2017 to primary completion in Apr 2020, 28 months.

Of 132 industry-sponsored phase 4 interventional studies under Diabetes Mellitus, Type 2, half reached primary completion within 19 months of starting (the median), counting those still running; a quarter within 12 and three quarters within 28. This study's 28 months is above that.

Counting every sponsor, half of 452 studies reached it within 24 months; a quarter within 13 and three quarters within 42.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 14, 2020, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
