Randomization of Single vs Multiple Arterial Grafts
(ROMA)
What this study is about
The primary hypothesis of ROMA is that in patients undergoing primary isolated non-emergent coronary artery bypass surgery (CABG), the use of two or more arterial grafts compared to a single arterial graft is associated with a reduction in the composite outcome of death from any cause, any stroke, post discharge myocardial infarction and/or repeat revascularization.
View original scientific description
The primary hypothesis of ROMA is that in patients undergoing primary isolated non-emergent coronary artery bypass surgery (CABG), the use of two or more arterial grafts compared to a single arterial graft is associated with a reduction in the composite outcome of death from any cause, any stroke, post discharge myocardial infarction and/or repeat revascularization. The secondary hypothesis is that in patients undergoing primary isolated non-emergent CABG, the use of two or more arterial grafts compared to a single arterial graft is associated with improved survival. Prospective event-driven unblinded randomized multicenter trial of at least 4,300 subjects enrolled in at least 25 international centers. Patients will be randomized to a single arterial graft (SAG) or multiple arterial grafts (MAG). Patients will be randomized in a 1:1 fashion between the two groups. Permuted block randomization with random blocks stratified by the center and the type of second arterial graft will be used to provide treatment distribution in equal proportion.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
