About this study
Official title: An Exploratory, Randomised, Double-blind, Multicentre, Placebo-controlled Study of RTP-026 to Assess Safety, Tolerability and Efficacy in Patients With ST-Elevation Myocardial Infarction (STEMI)
This is an exploratory, randomized, double-blind, multicentre, placebo-controlled study of RTP-026.
The study population will consist of men and women with documented evidence of ST-elevation myocardial infarction (STEMI) referred to primary Percutaneous Coronary Intervention (PCI).
Read the detailed description
An exploratory, randomized, double-blind, multicentre, placebo-controlled study of RTP-026 to assess safety, tolerability, and efficacy in patients with (STEMI).
The study population is men between 18-85 years and post-menopausal women up to 85 years with documented evidence of STEMI referred to primary PCI with acute onset of chest pain lasting <12 hours and neutrophil to lymphocyte ratio (NLR) in the range of 3-17 at hospital admission (Please refer to inclusion criteria).
The participants will be given three 30-minute intravenous infusions of RTP-026 or placebo (the investigational product). The first dose is to be initiated within 2 hours following the establishment of reflow after PCI, and the following two study treatments with 8-hour intervals.
The purpose of this study is to evaluate the safety, tolerability and efficacy of RTP-026 versus placebo in multiple doses.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing RTP-026 in people with ST Elevation Myocardial Infarction, run by ResoTher Pharma at 1 site in Denmark.
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 9 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: finished, as of the sponsor's last update on 24 Sep 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 Denmark. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in Cardiac Troponin T (cTNT) (time frame: 24 hours). The study lists 2 primary outcomes in all. 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 24 Sep 2026.
