Study summary

Heart failure (HF) is a heterogeneous clinical syndrome characterized by substantial inter-individual variability in pathophysiology and response to treatment. Precision medicine approaches are therefore needed to better account for this heterogeneity and tailor therapeutic strategies to individual patients. Virtual human twins represent one such approach, integrating multimodal clinical, biological, imaging, physiological, and omics data into patient-specific computational models to model disease mechanisms and predict individual therapeutic response.

VITAL-HF is a prospective cohort pilot study designed to clinically evaluate the ability of the VITAL cardiovascular virtual human twin to predict individual response to spironolactone in patients with HF. Adult patients with HF with left ventricular ejection fraction (LVEF) > 40% who have a clinical indication for spironolactone as part of routine care will be enrolled and followed for 3 months. The primary objective is to assess the ability of the VITAL cardiovascular virtual human twin to discriminate responders from non-responders to spironolactone. Response is defined as a ≥20% reduction in NT-proBNP levels 3 months after spironolactone initiation.

Virtual twin predictions will be generated for research purposes only and will not influence treatment decisions or patient management.

Terms in these criteria, in plain language(7)

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.

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.

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 authorised 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.

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.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

TIA (transient ischaemic attack)

A “mini-stroke”: temporary stroke-like symptoms caused by reduced blood flow to part of the brain, spinal cord or eye, without signs of a new stroke on a scan.

Stroke symptoms need emergency care at once, even if they go away.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

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.

Interventions

  • OtherData collection for the development and validation of the cardiovascular virtual human twin

    Multimodal clinical, biological, imaging, functional and patient-reported data will be collected to develop cardiovascular virtual human twins in patients with HFpEF. Data will include clinical characteristics, ECG, laboratory tests, echocardiography, CPET, bioimpedance, 6-minute walking distance, vascular and autonomic assessments. Additional research data will include cardiac MRI with gadolinium, CALAMARI recordings (ECG, SCG, PPG), spironolactone pharmacokinetic blood and urine samples, and blood samples for proteomic and metabolomic analyses. Questionnaires will assess quality of life, psychological factors, AI perceptions, trust and digital literacy. The collected data will be integrated to generate patient-specific virtual twins and assess their ability to predict individual response to spironolactone. Predictions will not influence clinical management.

Start is estimated for Nov 2026; primary completion for Feb 2029, 27 months later.

Of 1,118 non-industry interventional studies with no phase under Heart Failure, half reached primary completion within 29 months of starting (the median), counting those still running; a quarter within 16 and three quarters within 50. This study's planned 27 months is close to that.

Counting every sponsor, half of 1,354 studies reached it within 31 months; a quarter within 16 and three quarters within 52.

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.
