The Recruitment Ad Language IRBs Reliably Send Back

IRBs reject recruitment ads for a predictable short list of reasons. Here are the phrases that get flagged, a reusable ad skeleton, and the format-specific traps that cost sites weeks of review time.

By Trialflow Team

Recruitment ads get kicked back from IRBs for the same handful of reasons, over and over. None of them are mysterious. Most are avoidable if you know what reviewers are actually looking for before you write the first draft.

What the IRB Is Evaluating

An IRB reviews your ad as part of the consent process, not as marketing. The question in a reviewer's mind is: would a person reading this form an accurate impression of what they're being asked to do? That framing explains most of the revisions you'll get.

In practice, reviewers are checking four things:

  • Is the study clearly identified as research?
  • Are claims about benefit, safety, or efficacy absent or properly hedged?
  • Is compensation described without being the headline?
  • Is the eligibility information accurate and not overstated?

The Phrases That Trigger Revisions

Some language reliably gets flagged. Worth striking from your templates now:

  1. "New treatment" or "breakthrough." Implies efficacy. Use "investigational" and say explicitly that the drug or device is being studied.
  2. "Free treatment" or "free medical care." Reviewers read this as undue influence. "Study-related care at no cost to you" is usually acceptable, and it's more accurate anyway.
  3. "Safe" or "well-tolerated." You don't know that yet. That's why there's a trial.
  4. "You may qualify" paired with a long list of conditions. Fine in principle, but if the list reads like a diagnosis checklist, reviewers worry people will self-diagnose to get in.
  5. Compensation in the headline or in large type. Most IRBs want payment mentioned, not emphasized. Put it in body text, not the first line.
  6. "Doctors recommend" or implied endorsement by your institution without approval.

Build a Reusable Skeleton

The fastest path to approval is a structure you reuse across studies, with only the condition-specific parts changing. A workable skeleton:

  • Opening line: condition plus a research framing. "Researchers are studying an investigational medication for adults with moderate plaque psoriasis."
  • Who may be eligible: two or three high-level criteria, not the full I/E list.
  • What participation involves: number of visits, rough duration, key procedures in plain words.
  • Compensation and cost: one sentence, neutral tone.
  • Contact and identifiers: site name, phone or form, PI name if your IRB requires it, protocol number.

Format-Specific Traps

Social ads cause the most trouble because the approved copy and the delivered experience diverge. The ad text may be approved, but the image overlay text, the headline field, and the landing page all count as recruitment material. Submit them together. If your platform truncates text on mobile, submit the truncated version too — reviewers have started asking.

For text message outreach, submit the exact string including any link preview. For radio or video, submit the script and note that the voiceover will match verbatim.

Practical Submission Habits

Submit a small family of variants at once — one long-form, one short social version, one SMS — rather than returning three times. Keep a tracked log of what each IRB has approved and which phrasings were struck; central IRBs and local boards differ, and that institutional memory saves weeks on the next study.

Finally, re-check approved ads against the current protocol version. When an amendment changes eligibility or visit burden, your ads are now inaccurate, and that's a finding waiting to happen at monitoring.
