Study types
Healthy Volunteer Studies
Studies that look for people without the condition being studied, often to understand how a study product behaves in the body.
Interventional Studies
Studies where volunteers follow a plan set by the research team, such as taking a study product or following a defined schedule.
Observational Studies
Studies that collect information about what already happens in daily life without asking volunteers to change anything.
Behavioral Studies
Studies focused on habits, routines, sleep, activity, attention, or other everyday behavior.
Prevention Studies
Studies that look at approaches intended to reduce the chance of a condition developing.
Device Studies
Studies that look at how a device performs, how comfortable it is, or how people use it.
How trials work
Full walkthrough
A study is designed and reviewed
A research team writes a protocol describing the question being studied, who the study is looking for, and what participants would be asked to do.
Opportunities are published
Study locations publish listings describing the study type, the general expectations, and the visit schedule.
You express interest
Interest is simply a message saying you would like to learn more.
The independent program reviews fit
The study team, never this website, reviews whether their study is a fit.
Informed consent happens
If a study looks like a fit, the team walks through the consent document in detail.
Study visits follow a schedule
Visits, check-ins, and any activities follow the schedule written into the protocol.
Reading a listing carefully
Look for the study type, the age range, the visit count, the location, and how long the study runs.
Questions worth asking
Who reviews this protocol? How many visits are there and how long is each one? What happens if I want to stop? Who do I contact with a concern? What happens to my information?
Planning your time
Check travel time, parking, work schedules, and whether any visit requires an overnight stay.
Talking with your own provider
Your own licensed healthcare provider knows your history.
Keeping your records
Keep a copy of every document the study team gives you, including the consent form and the contact details for study questions.
Knowing what you control
Participation is voluntary from beginning to end.
What does Trial Opportunity Desk actually do?
We publish plain-language information about clinical research and let you browse general opportunity types. We do not run studies, decide who takes part, or provide medical advice.
Can you sign me up for a trial?
No. Every study is run by an independent program that sets its own protocol and its own participation criteria. If you ask us to, we can organize the interests you told us about and facilitate an introduction as a courtesy. That is not a guarantee of availability or acceptance.
What is informed consent?
It is the process where a study team explains the purpose, the schedule, what you would be asked to do, and the possible risks before you decide anything. You can ask questions, take the documents home, and step away at any point.
What happens during screening?
Screening is how an independent program reviews whether a study is a fit for you. It happens with that program, not with us. We never carry out screening or assessment.
What are study phases?
Research is usually organized in stages. Early stages involve smaller groups and focus on safety and how something behaves. Later stages involve larger groups and compare results across participants.
What protections do participants have?
Research is reviewed by independent ethics boards, and volunteers may leave a study at any time. Ask the study team who reviews their protocol and who to contact with concerns.
Stay in the loop.

Any trial programs or research organizations that users may be introduced to through Trial Opportunity Desk are independent organizations operating under their own protocols and eligibility criteria. Trial Opportunity Desk does not control, supervise, guarantee, or take responsibility for protocols, eligibility criteria, safety monitoring, outcomes, or conduct of any independent clinical trial program. Users should review the materials provided by the independent organization and consult their own licensed healthcare provider before deciding to participate.
