10 Myths About Clinical Trials — Debunked by a Research Physician
Fear and misinformation keep many patients from a decision that could genuinely change their health. Let’s set the record straight.
Clinical research has an image problem. Despite decades of scientific progress and strict federal regulations, many patients still imagine clinical trials as risky experiments conducted on uninformed participants. The reality could not be more different — but myths persist, and they prevent patients from accessing care that could genuinely help them.
Here are ten of the most common myths our research team hears — and the facts that replace them.
Here are ten of the most common myths our research team hears — and the facts that replace them.
Myth 1: Clinical trials are a last resort for people who have run out of options.
Fact: Most clinical trials today are testing new treatments for common conditions — diabetes, obesity, high cholesterol, fatty liver disease — and are open to patients who are being actively managed by their primary care physician. You do not need to have exhausted every other option. Many participants are relatively healthy adults seeking better management of a chronic condition.
Myth 2: I could be given a placebo and receive no treatment at all.
Fact: In trials where a placebo arm exists, participants are still closely monitored by a physician. More importantly, if an effective standard treatment already exists for your condition, you will never be denied it. Most modern trials compare a new treatment to the best existing treatment — not to a sugar pill. Your study physician will explain the design of any placebo component fully during informed consent.
Myth 3: Clinical trials are only done at big university hospitals.
Fact: The majority of clinical research in the United States is conducted at community-based research sites — places like Mission Research Institute in Gilbert, AZ — that are close to where patients actually live and work. Community sites are essential because they reflect the real-world patient population better than academic centers.
Myth 4: My personal doctor will be cut out of my care.
Fact: Your personal physician remains your primary care provider. Our research team supplements that relationship, does not replace it. We encourage participants to keep their personal doctors fully informed throughout any study, and we coordinate with them as needed.
Myth 5: Clinical trials are dangerous experiments.
Fact: Before any investigational drug is tested in humans, it passes years of laboratory and animal safety studies. Phase I trials then carefully test safety in a small number of people before moving to larger populations. Every study at Mission Research Institute is approved by an Institutional Review Board (IRB) — an independent ethics committee — and monitored by the FDA.
Myth 6: Once I sign up, I cannot leave.
Fact: Participation is always voluntary. You can withdraw from a clinical trial at any time, for any reason, without penalty — and without it affecting your relationship with your personal healthcare provider. Informed consent is not a binding contract.
Myth 7: The study team just wants my data — they do not care about me as a patient.
Fact: At physician-led research sites, your health and safety come first. You will have more face time with a physician during a clinical trial than in most routine primary care settings. Adverse events are taken seriously and reported immediately. Your wellbeing is not a secondary consideration — it is a regulatory requirement and a professional obligation.
Myth 8: I will be in debt if something goes wrong.
Fact: Medical care required due to a study-related adverse event is provided at no cost to participants. Study-related procedures, lab work, and medications are always free. You are also compensated for your time and travel.
Myth 9: I am too old — or too young — to qualify.
Fact: Most adult trials have a broad age range. Many studies specifically need older adults because the target condition is most prevalent in that population. There is rarely a blanket age cutoff that would exclude someone from all studies — eligibility is always study-specific
Myth 10: The pharmaceutical company is the one really in charge of my care.
Fact: The sponsor designs the study protocol and provides the investigational treatment, but your care at the research site is delivered by licensed physicians who are independent of the sponsoring company. The Principal Investigator at your research site has the authority — and the professional obligation — to protect your safety above the study’s commercial interests.
The most dangerous myth of all is that clinical research is not for people like you. It is — and the medicine of tomorrow depends on your participation today.
