About this study
Official title: Non-Steroidal Anti-Inflammatory Drugs Versus Conventional Treatment in Acute Myocarditis (INFLAMA Trial)
Prospective, randomized, multicenter, open-label clinical trial to evaluate the safety and efficacy of a 3-week ibuprofen tapering regimen compared to conventional analgesic treatment (acetaminophen) in patients with acute myocarditis and left ventricular ejection fraction ≥50%. The objective is to assess the reduction in late gadolinium enhancement on cardiac magnetic resonance imaging at 6-month follow-up.
Read the detailed description
The treatment for patients with uncomplicated myocarditis (left ventricular ejection fraction >50% without heart failure) is not currently well defined. Analgesic drugs are commonly used to manage pain. The use of nonsteroidal anti-inflammatory drugs (NSAIDs) among analgesics is controversial due to potential harmful effects observed in animal models. However, NSAIDs are the standard treatment for pericarditis, even when it is associated with mild myocardial involvement. In patients with acute myocarditis and normal left ventricular ejection fraction, observational studies have suggested that NSAIDs may have a beneficial effect in reducing late gadolinium enhancement (LGE) measured in cardiac magnetic resonance (CMR), an important prognostic marker in this population.
We plan to conduct a prospective, randomized, multicenter, open-label clinical trial to evaluate the safety and efficacy of NSAIDs versus conventional analgesic treatment in patients with uncomplicated acute myocarditis and left ventricular ejection fraction ≥50%.
Approximately 150 patients will be randomized 1:1 to NSAID treatment (ibuprofen tapering schedule during 3 weeks) or conventional treatment (acetaminophen or metamizole in case of allergy until pain resolution) during hospital admission. Patients will be followed for a 12-month period. Baseline CMR will be performed at initial hospitalization for acute myocarditis and at 3 and 6 months.
The primary objective is to assess the utility of ibuprofen versus conventional treatment with analgesics in acute myocarditis with preserved LVEF, in terms of reducing LGE on CMR at 6-month follow-up compared to baseline.

What is this clinical trial studying?
A Phase 3 study testing ibuprofen in people with Myocarditis Acute, run by Fundación Centro Nacional de Investigaciones Cardiovasculares Carlos III at 1 site in Spain.
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 6 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: looking for participants now, as of the sponsor's last update on 13 Feb 2026. 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 Spain. 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. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Fernando Domínguez Rodríguez, MD, PhD (+34 91 1916000, fdominguezr@salud.madrid.org), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in late gadolinium enhancement (measured in % relative to indexed myocardial mass) compared to baseline (CMR) at admission) (time frame: 6 months). 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 13 Feb 2026.
