A Study of the Safety and Efficacy of Nitric Oxide Reduction in Patients With Cardiogenic Shock After a Heart Attack

Plain-language summary
Tilarginine Acetate Injection is a new type of drug that temporarily stops the body from making a bodily substance called nitric oxide. The body may produce excess nitric oxide following severe heart damage leading to shock. During a heart attack, and especially after a blocked artery causing the heart attack is reopened, a large amount of nitric oxide is released into the heart muscle and into the blood. Normally small amounts of nitric oxide are good for the heart and blood vessels. However, when released in large amounts, such as during a heart attack, it may be harmful, by adding to the damage of the heart attack and lowering the heart's ability to pump blood to the body. It may cause blood pressure to be lowered and reduce the amount of blood flow to the body's vital organs. This may interfere with the body's organs being able to do their work. If Tilarginine Acetate Injection can stop extra nitric oxide from being made, the performance of the heart and blood flow to the organs may get better, which may result in the improvement of symptoms. The purpose of this study (TRIUMPH) is to investigate the safety and effectiveness of Tilarginine Acetate Injection compared to placebo (an inactive fluid that has no effect on the body but looks exactly like the medication being studied). The study will help determine whether Tilarginine Acetate Injection, by temporarily lowering the amount of nitric oxide released into the vital organs can improve blood pressure and the blood flow to the body's organs.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Confirmed myocardial infarction (heart attack)
* Confirmed persistent cardiogenic shock
* Confirmed patency of the infarct related artery (heart attack artery has been opened through the use of a blood clot dissolving drug or a balloon or angioplasty heart procedure)
* Less than 24 hour duration of cardiogenic shock (the time since the heart attack occurred and the artery was opened must be less than 24 hours)
Exclusion Criteria:
* Infection
* Other cause of shock (not heart attack)
* Shock due to heart valve disease
* Severe heart valve disease
* Right sided heart failure
* Shock due to arrhythmia (irregular heart rhythm)
* Severe kidney disease
* Aortic dissection (tear in aorta)
* Adult respiratory distress syndrome (ARDS) (severe lung inflammation)
* Severe brain damage
* Severe irreversible multi-system failure (failure of multiple body organs)
* Major chest or abdominal surgical procedure within 30 days except if prior CABG and reocclusion occurs
* Primary pulmonary hypertension (high blood pressure in the arteries of the lungs)
* Age younger than 18 years
* Requirement for emergency coronary artery bypass grafting (CABG) or infarct-related artery occlusion (heart attack artery completely blocked)
* Ongoing or recent participation in another clinical trial of an investigational drug
* Prior enrollment in this study or rapid resolution of cardiogenic shock before treatment (shock gets better before study starts)
* Positive pregnancy test in women…
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
