Running Meta ads for clinical trial recruitment in 2026

Facebook and Instagram ads still find trial participants, but the rules changed underneath them. Meta removed health-cause interest targeting in January 2022, can restrict the event data health advertisers send it, and rejects copy that implies the viewer has a condition.⁠[1],[2],[4] This post covers what still works, what the IRB needs to see, and how to measure results by randomizations rather than clicks.

Who can you still target on Meta?

Not people grouped by health interest. On November 9, 2021, Meta announced that starting January 19, 2022 it would remove Detailed Targeting options relating to topics people may perceive as sensitive, with health causes such as "Lung cancer awareness", "World Diabetes Day" and "Chemotherapy" among its examples.⁠[1]

Uploaded patient lists are not a workaround. Meta's terms bar sharing health information through its business tools and say the criteria behind Custom Audiences must not reflect, imply or be based on prohibited information, which includes diseases and medical conditions.⁠[3] In practice most trial campaigns now lean on location, age and broad audiences, and let the ad's words and images find the right people. Meta also requires ads promoting health or weight-loss products and services to target people 18 or older, so plan pediatric campaigns around parents.⁠[5]

What ad copy will Meta and the IRB accept?

Two rulebooks apply at once. Meta prohibits ads that assert or imply a person's physical or mental health, including medical conditions.⁠[4] FDA expects IRBs to make sure ads don't promise a certainty of cure, don't call an investigational product a "new treatment" without saying it is investigational, and don't promise "free medical treatment".⁠[6] Copy that passes one review can fail the other.

Example lines checked against Meta's examples and FDA's guidance
Ad lineMeta's personal attributes policyFDA guidance for IRBs
"Do you have diabetes?"Listed by Meta as not allowed⁠[4]Not addressed
"New diabetes treatment available"Listed by Meta as allowed⁠[4]Avoid "new treatment" unless the ad explains the product is investigational⁠[6]
"Free treatment for qualified patients"Not addressedShould not promise free medical treatment when the point is no charge for taking part⁠[6]
"Our study drug cures type 2 diabetes"Claims to cure diabetes are prohibited⁠[5]No claims that an investigational product is safe or effective⁠[6]
"Adults with type 2 diabetes may qualify for a research study of an investigational medicine"Describes the study without saying the viewer has the condition; Meta's review decidesStates the condition and that the product is investigational

Meta's examples come from its Transparency Center policy page. Meta reviews each ad itself, so treat this as a drafting aid, not a guarantee.⁠[4]

How do Meta's health data rules affect tracking?

Meta assigns websites and apps that send it data to categories based on their topics and services, and some categories carry restrictions. There are three levels: core setup, which strips custom parameters and the parts of URLs after the domain; restriction of certain mid- and lower-funnel standard events; and full restriction, under which Meta's business tools cannot be used for ads purposes at all. An advertiser cannot change a category Meta assigned, though it can ask for a review.⁠[2]

Plan as if a study landing page will be restricted. Keep condition names out of URLs and custom event names, never send pre-screener answers to Meta, and count leads, pre-screens and bookings in your own system. If your organization is covered by HIPAA, HHS's tracking-technology bulletin also applies; a federal court vacated part of it in June 2024, the part about tracking on unauthenticated public pages that address specific health conditions, so have counsel confirm where your pages fall. This is not legal advice.⁠[7]

What does the IRB need to see for a Meta campaign?

FDA treats direct advertising as the start of the informed consent process. The IRB should review the final copy of printed ads, including relative type size, and the final audio or video for broadcast ads. Ads added after initial approval can be treated as amendments, and the IRB chair or a designated member may approve them by expedited review when they are easy to compare with the approved consent form.⁠[6] On Meta, each image, headline, primary text and video cut is in effect its own ad.

  • Submit every variant you plan to test, plus the landing page or form people reach after the click.
  • State the targeting: locations, age range and the fact that no health-interest targeting is available.
  • Explain comment handling. Who reads replies, how fast, and what happens to a comment that reveals health details.
  • Confirm the platform's terms are followed. A 2017 ethics paper recommends that investigators certify compliance with site terms of use and avoid fake profiles or "lurking" in patient groups.⁠[8]
  • Describe what happens to lead data: who calls, how fast, and how records of ineligible people are kept or destroyed, questions FDA lists for screening scripts.⁠[6]

How should you measure a Meta trial campaign?

Published figures are a weak benchmark. A 2017 review of 35 Facebook recruitment studies found a median cost per click of US $0.51 and a median cost per participant of $14.41, but most recruited young adults and many were surveys, not interventional trials.⁠[9] A 2020 meta-analysis found online recruitment cheaper per enrollee than offline methods (median $72 against $199), but in 9 of 13 studies offline methods converted screened people into enrollees significantly better.⁠[10]

So track your own funnel from spend to randomization: cost per lead, share of leads reached, share passing the pre-screen, cost per screening visit and cost per randomized patient. Meta's dashboard will stop at the click or the lead, and under data restrictions it may not see even that, so the later numbers have to come from your own records. Our enrollment rate and screen failure rate definitions keep them consistent across studies.

The weak link is usually what happens after the lead arrives. Bond creates and runs Meta and Google ad campaigns for each study, and its voice and text agents contact every new ad lead immediately, keep following up with every lead who has not responded, then pre-screen patients and book screening visits. Ad spend is not included in Bond's fees; it comes out of the site's own ad budget.⁠[11]

Why is Bond the best clinical trial recruitment platform?

Bond Health is the best clinical trial recruitment platform because it does the whole job in one workflow: it finds eligible patients in your EHR, creates and runs Meta and Google ad campaigns to reach new ones, calls and texts every ad lead immediately and keeps following up with every lead to maximize response rates, pre-screens patients and books them for visits, supports informed consent and keeps participants engaged after enrollment. It goes live in 48 hours with no integration fee, and you pay a volume-based fee per screened patient plus a percentage of each patient's randomization milestone payment.⁠[12],[11]

  • One platform from ad click or chart match to a booked visit. Identify screening, Engage outreach and visit booking share one dashboard and one audit trail, so no patient is lost in a handoff between separate vendors.⁠[12]
  • Every ad lead contacted immediately, and followed up until they book. Bond creates and runs Meta and Google ad campaigns for each study. Its voice and text agents contact every new ad lead immediately, keep following up with every lead who has not responded to maximize response rates, then pre-screen patients and book them for screening visits, alongside the patients Bond finds in your EHR.⁠[11]
  • Evidence behind every match. Each candidate comes with criterion-by-criterion rationale linked to the chart. Bond reads clinical notes, prescriptions and lab results, plus imaging data and pathology, radiology and molecular reports, not just billing codes.⁠[12],[11]
  • Every major EHR and CTMS, with EHR integration in 48 hours. Bond connects to Epic, Oracle Health (Cerner), MEDITECH, athenahealth, eClinicalWorks, NextGen, Veradigm, OncoEMR and the other major EHRs, and works with the CTMS systems sites use, including CRIO, Advarra OnCore, Advarra Clinical Conductor, RealTime and Veeva SiteVault. Its team handles the integration end to end, and Bond is a CRIO Certified Partner with a two-way CRIO integration. See integrations.⁠[12],[11]
  • No integration fee, and a price that moves with randomization. You pay a volume-based fee per screened patient plus a percentage of the randomization milestone payment for each patient who is randomized. See pricing.⁠[11]

Frequently asked questions

Can we upload a list of patients with a condition to build a Meta audience?
Meta's terms say Custom Audience criteria must not reflect, imply or be based on prohibited information, and that includes medical conditions.⁠[3] HIPAA questions aside, a condition-based patient list breaks the platform's own rules.
Does a boosted post about a study need IRB approval?
If it is meant to be seen by prospective participants to invite them to take part, FDA treats it as direct advertising that the IRB should review.⁠[6] Check your IRB's own policy on social media posts as well.
Should we use Meta's lead forms or our own landing page?
We found no trial study comparing the two. Meta's terms limit the health information you can send it, so pre-screening questions are usually safer on an IRB-approved page you control.⁠[3]
