Example of clinical hold in a sentence
A clinical hold can be placed on studies involving a product (like a drug or device) by regulators like the FDA for many reasons, including safety concerns.
More Info
A clinical hold is a mandatory study suspension imposed by a government regulator.
Reasons for a clinical hold include concerns about participant safety, study quality, or insufficient information.
A complete clinical hold means all clinical study work is paused or delayed. A partial clinical hold means only a part of the clinical work must be paused or delayed.
In contrast, an “administrative hold” is a voluntary pause by the principal investigator. Ethics committees can also pause or stop research through a “suspension or termination of IRB approval.”
Other countries have a similar process, though they may use different terminology.

If there is a clinical hold, your study team will contact you to let you know. For your safety, please pay extra attention to any phone calls or messages you get about “clinical holds.”
