Clinical trial advertising

Clinical trial advertising that reaches eligible participants.

Recruitment ads for research studies, built for IRB review and Meta's health advertising rules.

Most of the people who would qualify for your study are not in your database and have never been asked. Advertising on Facebook and Instagram puts the study in front of them, in their area, in plain language, and sends the ones who recognize themselves to your screener. TrialFill builds the creative, runs the campaigns, and keeps every ad inside the rules your IRB and the platforms enforce.

The basics

What is clinical trial advertising?

Definition

Clinical trial advertising is any print, digital, or broadcast material used to recruit people into a research study: social media ads, flyers and posters, radio and TV spots, email, and the landing pages and screeners those ads link to. The FDA treats it as the start of the informed consent process, not ordinary marketing, so every ad is reviewed by an Institutional Review Board (IRB) before it runs.

That changes how a recruitment ad is written. A product ad tries to persuade; a clinical trial ad has to inform. It says it is research, names the institution, describes the study in plain language, and gives just enough eligibility detail for the right people to recognize themselves and click through to the study team's screener. Clinical trial recruitment advertising is also the main way to reach eligible people outside a site's own patient list: most participants who would qualify have never been asked, and the recruitment statistics show recruitment, not the science, is what puts most studies behind schedule.

The rules

The rules every clinical trial ad has to follow

Two reviewers decide whether an ad runs: your IRB, working from FDA guidance, and the ad platform. These six rules cover nearly every rejection. The full detail is in the clinical trial advertising guidelines.

IRB

Approved before it runs

Every ad, image, script, landing page, and screener is reviewed by the IRB first, in final form. Any change after approval goes back for review.

FDA guidance

No safety or efficacy claims

An ad cannot say or imply that the product being studied is safe, works, or is better than other treatments.

FDA guidance

Say it is investigational

"New treatment" or "new drug" needs to say the product is investigational, and "free treatment" should not be used when it only means participation costs nothing.

FDA guidance

Payment stated, not emphasized

Compensation can be mentioned, but not as the hook: no large or bold dollar amounts, and never in the headline.

FDA guidance

Only what people need to decide

The condition or purpose, a summary of eligibility, the time commitment, the location, and who to contact. Nothing more is needed.

Meta

No "you" plus a condition

Meta does not allow ads that imply the viewer has a health condition, and condition targeting is gone. Ads speak in the third person. See Facebook ads for clinical trials.

Where the ads run

Clinical trial advertising channels

TrialFill runs recruitment campaigns on Meta's platforms, Facebook and Instagram, because that is where most eligible participants can be reached. The ads work best on top of the free channels every study should use first. For the evidence on how online recruitment performs against traditional methods, see the recruitment statistics.

Meta: Facebook and Instagram

Where the budget goes

Meta reaches people who are not searching for anything. That matters for recruitment, because most eligible participants are not looking for a study. They are scrolling, and a clearly written ad in their feed is often the first time they learn one exists.

  • Targeting by geography, age, and language, within the radius of your site
  • Image and short-video creative that explains the study in plain language
  • Low cost per click: $0.42 on average across nine university campaigns
  • Health condition targeting is no longer available, so the ad itself does the qualifying

Your existing channels

What the ads build on

Paid ads are not a replacement for the free channels a study team already has. They reach the people those channels miss, so the plan starts by using everything already available.

  • Your institution's study listing pages and recruitment office
  • Volunteer registries such as ResearchMatch, and your ClinicalTrials.gov record
  • Flyers, posters, and clinic referrals near your site
  • Your patient database, where your IRB allows contacting it
Use these first. Add ads when they stop producing enough inquiries.
No health-based targetingCampaigns never target by condition, diagnosis, medication, or medical interest. Geography, age, and broad behavior only.
No retargeting or list buildingPeople who click are routed to your screener. They are not added to audiences, re-marketed to, or used to build lookalikes.
No third-party health dataNothing is purchased, matched, or inferred about anyone's health. The ad speaks generally and people self-identify.

How a campaign runs

From approved materials to qualified inquiries

Four steps, and your team sees everything before a participant does. The full engagement, including reporting and what your team handles, is on the services page.

1

Creative from your approved materials

Ad copy, headlines, and imagery are built from the recruitment language your IRB has already approved. Nothing is invented or taken off-protocol.

2

Packet prepared for review

Every ad variation, with its image and destination, is assembled into a single document formatted for IRB submission alongside your protocol.

3

Platform-compliant build

Campaigns are structured to Meta's health advertising policies from the start, so an approved ad does not get rejected for an avoidable platform reason.

4

Launch, optimize, report

Ads go live in your area. Budget moves toward what produces qualified inquiries, and you get a weekly report in plain numbers.

What an IRB-ready ad contains

Clinical trial recruitment ad example

Anatomy of a compliant recruitment ad

A recruitment ad has to satisfy two reviewers with different rules: your IRB and the platform. These are the elements that get an ad through both, shown on a sample for an illustrative study.

  • 1
    It says it is research

    The first sentence names the institution and calls it a research study. No ad reads like a treatment offer or a clinic promotion.

  • 2
    Plain-language purpose

    What the study is about, in words a participant would use. No mechanism, no drug name unless the IRB has approved it, no implied benefit.

  • 3
    Eligibility summary

    Age range and the one or two criteria that let a person recognize themselves. Full screening happens on your form, never in the ad.

  • 4
    Headline that qualifies, not persuades

    "Now enrolling adults 18 to 55" tells the right people to keep reading. It does not promise outcomes or urgency.

  • 5
    Compensation as a fact, not a hook

    When the IRB approves it, compensation appears as one plain sentence in regular text. Never in the headline, never with a dollar figure in large type.

  • 6
    IRB number and PI

    Where your institution requires it, the IRB approval number and principal investigator appear on the ad itself, not just the landing page.

  • 7
    Destination is your screener

    The button goes to your approved form or landing page. Contact information is captured there; screening questions are shown for self-assessment, so no health information is transmitted to TrialFill.

Three variations

Clinical trial advertising examples

Three ways to say the same approved thing

Every study ships with a small set of ad variations so the campaign can learn which framing reaches the right people. All three draw from the same approved language and carry the same required elements; only the angle changes. Shown here for the same illustrative study.

Variation A

The plain research ad

Primary text
Riverside University is conducting a research study on sleep and memory in adults. Volunteers ages 18 to 55 who sleep fewer than six hours on most nights may be eligible. Two visits to the Riverside campus. Compensation for time and travel may be available.
Headline
Sleep and Memory Research Study
Description
Adults 18 to 55 may qualify. IRB #RU-2026-0417.
Institution-forward and literal. Usually the strongest performer with older audiences and the easiest to clear review.
Variation B

The contribution ad

Primary text
Help researchers understand how sleep affects memory. The Riverside University Research Center is enrolling adults ages 18 to 55 who get fewer than six hours of sleep most nights. Participation involves two campus visits.
Headline
Help Advance Sleep Research
Description
Now enrolling adults 18 to 55. IRB #RU-2026-0417.
Leads with purpose rather than eligibility. Reaches people motivated by contributing, which some study populations respond to more than others.
Variation C

The now-enrolling ad

Primary text
Now enrolling: a research study on sleep and memory for adults ages 18 to 55 who sleep fewer than six hours on most nights. Conducted by the Riverside University Research Center. Two visits. Compensation for time and travel may be available.
Headline
Now Enrolling Adults 18 to 55
Description
Riverside University Research Center. IRB #RU-2026-0417.
Eligibility-first. Filters hardest at the headline, which tends to produce fewer clicks but a higher share of qualified inquiries.

More samples by study type, plus a recruitment flyer, a Stories ad, and before-and-after rewrites: clinical trial advertising examples.

All three are samples for the same fictional study. Image creative for each variation is built to match: a clean study-branded graphic, a clinician or campus photo, or a plain text-on-color card, depending on what the IRB and the platform allow.

What it costs

How much clinical trial advertising costs

A set price for the work. Ad spend at cost.

Two numbers, kept separate so your budget office can see exactly where each dollar goes. For published benchmarks on what recruitment costs per click and per enrolled participant, see recruitment cost statistics.

Figures from Meta Ads Manager for TrialFill's University of Alabama at Birmingham campaigns, September 2023 to October 2026. Study-by-study numbers are on the results page; to size your own budget, use the recruitment rate calculator. The full breakdown, from cost per click to cost per enrolled participant, is in the clinical trial advertising cost guide.

Service fee

Per-study pricing, agreed up front

Covers creative, the IRB packet, campaign build, launch, and the first 60 days of weekly optimization and reporting. Studies that need longer continue at a simple monthly rate, agreed up front. No hourly billing, and no charge to pause and restart when a protocol amends.

Ad spend

Paid to the platforms, never marked up

Runs through your institution's ad account or is passed through at cost with the platform receipts attached. For a single-site academic study, monthly ad budgets typically range from a few hundred to a few thousand dollars, set by you and adjusted as the numbers come in.

Reporting

Cost per qualified inquiry, every week

You always know what each inquiry is costing and how that is trending, so budget decisions are made on evidence rather than estimates.

What moves the cost per inquiry

  • How narrow the criteria areA study for adults 18 to 65 costs less to fill than one for a specific age band with three exclusions. The ad has to reach more people to find each eligible one.
  • How large the recruitment area isA 25-mile radius around one site is a small audience. Statewide or multi-site campaigns have more people to reach but need more budget to reach them.
  • How sensitive the condition isSome conditions carry platform restrictions that limit creative and placement options, which raises the cost of each click that gets through.
  • How quickly you need to enrollA tight timeline means spending faster, which usually means paying a bit more per inquiry than a campaign that can pace itself.
Getting help

Choosing a clinical trial advertising agency

A general marketing agency can buy ads. A clinical trial advertising agency has to get them through the IRB and Meta's health rules first, without taking your participant data. Six things to check before you hire anyone, TrialFill included. For a side-by-side of the main types of recruitment vendors, see clinical trial recruitment companies compared.

1

IRB experience

Ask for an example of an ad packet they have prepared for IRB submission, and how they handle a change after approval.

2

Where the data goes

Interested people should land on your own screener. If the agency collects responses, it holds your participants' information.

3

Ad spend at cost

You should pay the platform's actual cost and see the receipts, separate from the fee for the work.

4

Health policy fluency

They should know Meta's personal attributes rule and how to target without health data, not promise condition targeting.

5

Weekly, plain reporting

Cost per inquiry and inquiry volume every week, not a monthly impressions report.

6

Who actually runs it

The person you talk to should be the person making changes, with no handoffs to a junior team.

Common questions

Clinical trial advertising questions

Platform and IRB rules in short form. The clinical trial advertising guidelines cover IRB review of ads in depth, and the compliance page explains how TrialFill works within each rule.

Clinical trial advertising is any print, digital, or broadcast material used to recruit people into a research study, from a Facebook ad or a flyer to a radio spot or a landing page. FDA guidance treats it as the start of the informed consent process, so it is reviewed by the IRB before it runs and limited to what a person needs to decide whether they may be eligible and interested.

Under FDA guidance, an ad may include the name and address of the investigator or facility, the condition or purpose of the research, a summary of eligibility criteria, a brief list of benefits if any, the time commitment, and who to contact. It should not claim or imply the product is safe or effective, call it a new treatment without saying it is investigational, promise free treatment, or emphasize payment.

Yes. Recruitment materials are reviewed by the IRB before they run, and that includes digital ads, images, landing pages, and screener wording. TrialFill prepares the full ad set as a packet formatted for submission alongside your protocol, and any change after approval goes back for review.

Yes. Meta permits recruitment advertising for research studies, but its health advertising rules shape how the ad is written and targeted. Ads cannot imply that the viewer has a condition, and targeting by health condition or medical interest is no longer available. Compliant campaigns speak generally, let people self-identify, and target by geography, age, and language instead.

There are two parts: the ad spend paid to the platform and the fee for the work. Across nine Meta campaigns for university research studies, TrialFill averaged $0.42 per link click and $6.35 per 1,000 impressions. For a single-site academic study, monthly ad budgets typically run from a few hundred to a few thousand dollars. TrialFill prices the work per study, agreed up front, with ad spend passed through at cost.

Usually, if the IRB approves the wording. FDA guidance says an ad may state that participants will be paid but should not emphasize the payment, for example with a large or bold dollar amount. Some IRBs allow an amount in plain text; others only allow a statement that compensation is offered.

Clinical trial advertising is the paid or published material aimed at potential participants, such as social ads, flyers, and radio spots. Clinical trial marketing is the broader plan around it: study branding, the landing page or screener, community outreach, referral programs, and how inquiries are followed up. Both have to stay within IRB-approved language.

By geography, age range, and language, never by health condition, diagnosis, or medical interest. The ad does the qualifying: it describes the study in plain language and states who may be eligible, so the people who respond are the ones who recognize themselves in it. No health data is collected, inferred, or used for retargeting.

Most people who would qualify for a study are not searching for one. Facebook and Instagram reach people in the recruitment area while they scroll, which is often the first time they learn a study exists. Across nine Meta campaigns for university research studies, TrialFill averaged $0.42 per link click. TrialFill runs recruitment campaigns on Facebook and Instagram only.

Yes. When institutional policy requires it, TrialFill builds and manages the campaign inside your organization's Meta ad account, so ad spend stays on your side and your team retains ownership of the account, the data, and the history. Otherwise TrialFill runs the campaign and bills ad spend at cost with platform receipts.
