It’s highly unlikely to experience drug-drug interactions in a research trial. In fact, because research trials are designed in part to eliminate medical risks, your odds of a drug-drug interaction in a research trial are actually lower than if you go to your doctor for a new prescription.
Drug-drug interactions are situations wherein one drug can increase, decrease, or change the effect of another drug. Even though many of these interactions are minor, we eliminate all drug classes that could interact in any way with a study drug used in a research trial. Our goal is to eliminate anything that could increase risk or muddy results.
Research trial rules are far stricter than those in normal medical care. If a patient is on a medication we believe could interact with a study drug, he or she is ineligible to take part in the research trial.
