Fill your trial.
Faster.
Patient recruitment for clinical trials through Facebook and Instagram advertising that sends pre-screened inquiries to your screener, without flagged ads, agency overhead, or the wait.Facebook and Instagram campaigns that send pre-screened inquiries to your screener.
A behind-schedule study means a PI asking hard questions, a timeline slipping, and a budget burning while the clock runs. It usually isn't the science. It's that recruitment stopped working.
You have three options. Hire a big agency, pay $10k+ and a monthly retainer, and become one account in their stack. Run the ads yourself and risk a rejected campaign or a flagged ad account right when you need enrollment most. Or hand it to a specialist firm that does only this: fills studies, fast, at a price agreed up front, with a dedicated lead who actually runs your campaign. That's TrialFill.
Built from your approved materials and designed to clear review the first time.
Meta health-policy expertise that protects your ad account.
People who passed your screener's self-assessment and left contact details, routed to your team to confirm eligibility.
Budget moves toward what works. You always know your cost per qualified inquiry.
Agreed before work begins. No hourly billing, no surprises.
A dedicated specialist leads your study from kickoff to reporting. No account managers, no handoffs to a junior team.
That difference is the whole point. A general marketing agency has to learn your world on your dime. TrialFill already works inside it, which is why campaigns move faster and clear review the first time.
Creative is built from your approved study materials and prepared to move through your institution's review process, not held up by it.
Health and clinical advertising has strict rules. Campaigns are built to comply from the start, protecting your ad account from flags and rejections.
The goal isn't traffic. It's potentially eligible, pre-screened people arriving at your screener for study staff to confirm and take forward.
When a study requires campaigns to run inside your institution's own ad accounts, TrialFill works within that setup.
Recruitment, not the science, is what puts most studies behind schedule. The numbers explain why, and where the opportunity is.
The participants you need already exist. Most are not your existing patients, and most have never been asked. Closing that gap is the entire job. See all 35 clinical trial recruitment statistics, or size your own study with the recruitment rate calculator.

No vanity metrics. Every campaign is judged on the only numbers that matter to you: qualified inquiries, cost per inquiry, and time to enrollment. A qualified inquiry is someone who passed the self-assessment questions on your screener and submitted contact information. Eligibility is always confirmed by your study staff, never by TrialFill.

Yes. Many teams bring in TrialFill specifically after flyers, databases, and referrals have stopped producing. A stalled study is the most common reason to start.
Not necessarily. TrialFill can drive participants to REDCap, FormAssembly, or your institution's approved screener. If a landing page would help, that can be built too.
Always. Creative is developed from your approved study materials and submitted through your institution's review process before launch. Nothing runs without sign-off.
Yes, when your study requires it. TrialFill works within your institution's ad accounts and approval workflows whenever that's the setup.
