I consent to OpenTrials using the general health condition and contact information I provide to identify potential clinical trial matches. I understand that OpenTrials will notify me when a potential match is found, and that my contact information will only be shared with the specific research team for that trial if I affirmatively respond to indicate interest. I understand that a match or my expression of interest does not confirm eligibility or enrollment. Eligibility is determined solely by the research team. I may withdraw this consent, or delete my information, at any time.

Participation can take different forms

Some studies seek participants living with a particular health condition. Others need healthy volunteers to help researchers understand health, prevention, or how an intervention works.

Discover relevant studies

Share a few preferences so future matching can focus on suitable study areas.

Stay in control

Learning about a study never obligates you to participate.

Protect your privacy

Profile details will follow clear consent and privacy practices.

Support research

Volunteers make clinical research possible with or without a health condition.
