Can I leave a clinical trial after signing the consent form?

Yes. Signing a consent form doesn't lock you into a clinical trial. You have the right to leave a trial at any time, whether that's shortly after joining or well into the study.

This right is part of informed consent, which is designed to be an ongoing process rather than a single decision made once. Along with the right to leave, you also have the right to ask questions at any point and the right to take part in the first place, if you choose to.

If you're considering leaving a trial, it can help to talk with the study team about what leaving would involve for your care going forward, but this is a conversation, not a requirement — the decision to stay or go is yours. If you decide to leave, your regular medical care can typically continue outside of the trial.
