Studies you may be able to join near Portland

These studies are recruiting through partner research networks. We may be paid a referral fee if you complete their screening form — this never changes what you pay (nothing) or the compensation the study offers you.

See which clinical studies you may qualify for

A partner research network matches volunteers with studies that are currently enrolling in the United States. You answer a few screening questions about your health and where you live; if a study looks like a fit, its team contacts you to confirm eligibility.

Screening is free and takes a few minutes. Eligibility and any compensation are confirmed by the study team, not by this site.

Contact the research site through the registry page, complete a short phone screen, then attend an in-person screening visit. If you qualify, the study team walks you through the informed consent document, which details every procedure, risk and payment before you commit. You can withdraw at any point, and enrollment is always free.

Frequently asked questions

Do I need to be sick to join a clinical trial in Portland?
No. Many studies recruit healthy volunteers, especially early-phase studies run at dedicated research centers. Others need participants diagnosed with a specific condition. Every trial lists its eligibility criteria — age range, condition, medications — and the study team screens you before enrollment.
How do I join a study in Portland, OR?
Pick a study that matches your profile, contact the research site (or apply through the study links on this page), pass a phone pre-screen, then attend an in-person screening visit. If you qualify, you review and sign the informed consent and the study begins. The process typically takes 1-3 weeks.
Is compensation for clinical trials taxable?
In the U.S., clinical trial compensation is generally considered taxable income, and research sites may issue a 1099 form for payments above $600 in a year. Reimbursements for travel or meals are typically treated differently. Consult a tax professional for your situation.
What is the difference between a research center and a hospital study in Portland?
Dedicated research centers (listed on this page with their Google ratings) run studies as their core business — often healthy-volunteer and vaccine studies with structured compensation. Hospital and university studies tend to focus on patients with specific conditions. Both types are registered and IRB-supervised.
Can I be in more than one clinical trial at a time?
Generally no — most studies exclude participants currently enrolled in another trial, and paid Phase 1 studies enforce a washout period (often 30 days or more) between studies. Frequent healthy volunteers in Portland typically complete one or two studies per year.
