Study summary

This is a randomised, placebo-controlled, double-blind, parallel-group, international, multicentre, Phase IV study to investigate the effects of dapagliflozin on cardiac substrate uptake, myocardial efficiency and myocardial contractile work in T2D patients. Eligible subjects with T2D before randomisation and fulfilling all of the inclusion criteria and none of the exclusion criteria will be randomised in a 1:1 ratio to dapagliflozin 10 mg or placebo once daily and treated for six weeks. The study includes five visits.

Read the detailed description

The following will be assessed at Baseline and at the end of the treatment period;

  1. MRI scanning in order to assess cardiac function and morphology. The MRI scanning will be made after fasting for at least 6 hours in the same time of day at all visits. The cardiac MRI examination will be performed in accordance with a pre-defined MRI protocol, with the total scan time at each visit estimated to 45 minutes. Images from all sites will be analyzed centrally at the core-lab using a dedicated software package and certified analysts.
  2. CT-PET scanning will be made to assess myocardial function and metabolism, as well as fatty acid metabolism in brain, liver and kidney cortex. The CT-PET scanning will be made after a fast as well as abstinence from nicotine, alcohol and caffeine for at least 6 hours at the same time of day at all visits.

    • A cardiac 11C-Acetate PET/CT examination is performed (IV 400 MBq 11C-Acetate).
    • A cardiac 18F-FTHA PET/CT examination is performed (IV 150 MBq 18F-FTHA). The subject is further examined by PET/CT over the liver, kidney cortex and brain (in this order) for uptake of 18F-FTHA. Arterialized venous samples are acquired throughout to assess P-NEFA and 18F-FTHA metabolism by metabolite analysis

Terms in these criteria, in plain language(12)

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.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorized to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

HbA1c

A blood test of average blood sugar over the past two to three months, given as a percentage or in mmol/mol. 6.5% (48 mmol/mol) or more is the usual threshold for diabetes, normally confirmed by a second test.

LVEF (left ventricular ejection fraction)

The share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

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.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Child-Pugh class

A score of how well the liver works in people with liver disease such as cirrhosis: class A is mild, B moderate and C severe.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

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.

GFR and eGFR (kidney filtering)

GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².

Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.

What researchers measure

Primary outcomes

  1. Adjusted Mean Change From Baseline in Global Longitudinal Strain of the Left Ventricle (GLSLV) at End of Treatment.

    Patients underwent magnetic resonance imaging (MRI) examination to determine the GLSLV, which is expressed as a percentage. The least square mean (LSM) change from baseline estimates were generated from an analysis of covariance (ANCOVA) model with treatment and baseline value of the endpoint as covariates.

    Time frame: Baseline (Day 1) and end of treatment (Day 42)

Secondary outcomes

  1. Adjusted Mean Change From Baseline in Myocardial Efficiency at End of Treatment.

    A clinical radiologic assessment of acquired computed tomography and positron emission tomography (CTPET)-\[11C\]-acetate images was performed to determine myocardial efficiency. The myocardial efficiency calculation was based on an estimate of energy used for producing LV contractile work (mean arterial pressure (MAP) x stroke volume (SV) x heart rate (HR) / myocardial mass) compared to the total cardiac work (calculated based on the total myocardial oxygen consumption per myocardial mass) and is expressed as a percentage. The LSM change from baseline estimates, were generated from an ANCOVA model with treatment and baseline value of the endpoint as covariates.

Ran from Feb 2018 to primary completion in Mar 2019, 12 months.

Results were first posted in Mar 2020, 1 year after primary completion.

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 12 months is below that.

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

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 Apr 27, 2020, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
