A signature records a decision. It does not replace understanding.

What informed consent should do

The consent process should help you understand the study’s purpose, procedures, duration, possible benefits, foreseeable risks and discomforts, alternatives, costs, compensation, privacy practices, injury information, and contacts. It should make clear which activities are experimental and that participation is voluntary.

You should have an opportunity to read the document, ask questions, and consider the decision without undue pressure. Translation or interpretation should be available when appropriate. Ask for a copy of anything you sign.

Questions that reveal the design

• What is the primary outcome, and when is it measured?
• Will assignment be randomized? Who will know the assignment?
• Could I receive placebo or standard care?
• What procedures would I receive outside the study?
• Which risks are known, and what remains uncertain?
• What happens if the intervention is stopped?

Privacy, specimens, and future use

Ask what information identifies you, who can inspect records, whether data are coded, how long information is retained, and whether specimens or data may be used for future research. The form should explain applicable choices and limits to confidentiality. De-identification lowers some risks but may not eliminate them.

Leaving a study

You generally may withdraw. Ask whom to notify, whether a final safety visit is recommended, whether collected data will remain in the research record, and what happens to stored specimens. In some circumstances, an investigator may also end participation for safety, protocol, or administrative reasons.

Independent support

Consider discussing the study with a clinician who is not part of the research team and knows your health history. You may also ask how to contact the institutional review board or ethics committee about participant rights. Phasentra Research does not provide legal or medical advice and cannot interpret a specific consent form for you.
