No, clinical trials should never cost you anything to join.
In fact, most studies cover the full cost of the treatment being tested, as well as study-related tests and visits. Many also offer support for transportation, meals, childcare, or other expenses — especially if participation takes time out of your day. If any costs are your responsibility, they will be clearly explained before you agree to take part. You’ll never be surprised with a bill.
Yes — and we encourage it.
Participating in a clinical trial doesn’t replace your relationship with your regular healthcare provider. You can (and should) continue to see them for all your usual care. In fact, some trial teams work closely with your doctor to coordinate care. You can also share updates or ask your doctor for input before making decisions about joining or continuing in a study.
You can leave the trial at any time — for any reason.
Your participation is completely voluntary. If you decide it’s not the right fit for you, you can withdraw at any point without penalty or pressure. Leaving a study won’t affect your future medical care, your relationship with your providers, or your ability to take part in research in the future. It’s your body and your decision, always.
Your personal health information is protected by law and strict research protocols.
All clinical trials follow data privacy regulations (like GDPR or HIPAA) to keep your identity and medical information safe. Your name and identifying details are kept confidential and are not shared with anyone outside the study team. In most cases, data is de-identified before being analyzed or published. If you have questions about how your information will be used, the research team will explain it clearly — and you have the right to ask at any time.
It depends on the study — but more people are eligible than you might think.
Each trial has its own criteria based on age, health history, medications, or diagnosis. These aren’t meant to exclude people unfairly — they help ensure the study is safe and accurate. That said, modern research is becoming more inclusive, with broader eligibility to reflect real-world patients. If you’re interested, it’s always worth asking.
Every clinical trial carries some level of risk — and you deserve to know what they are.
You might experience side effects, the treatment might not work, or it might not be better than your current care. Before you decide, the research team will explain all known risks clearly and answer your questions. You’ll also be monitored throughout the study and supported if any problems arise.
Not always — and never without your knowledge.
Placebos (inactive treatments) are only used in some trials, usually when there’s no current standard treatment. If you might receive a placebo, that will be clearly explained during the consent process. You’ll know before you agree to join. Many trials today compare new treatments to existing ones — not placebos — especially when proven options already exist.
In many cases, yes — but it depends on the study.
Yes — in most patient-centered trials, results are shared after the study ends.
You’ll have direct contact with the study team the whole way through.
Clinical trials aren’t hands-off. You’ll be given contact information for a nurse, coordinator, or doctor involved in the trial. You can reach out any time with concerns, side effects, or questions. You’re never expected to just “tough it out” — you’re supported every step of the way.
