What is a humane endpoint?

What is a humane endpoint?

• A. The point at which pain or distress in an experimental animal is prevented, terminated or relieved
• B. A predefined statistical cutoff for data analysis
• C. The endpoint of a study when animals are euthanized due to age
• D. A timepoint for feeding schedule changes

Answer: (A)

Humane endpoints focus on preventing or relieving pain and distress in animals used in research. They establish a predefined moment at which the animal’s suffering is stopped—either by terminating the animal’s participation in the study or by taking active measures to relieve its discomfort. This approach is about welfare and minimizing harm, aligning with ethical guidelines for animal research. That definition fits best because it directly describes a criterion for stopping or alleviating suffering, not just a procedural or logistical aspect of a study. Other options describe endpoints unrelated to an animal’s welfare in the moment—such as a statistical cutoff for data analysis, the study ending due to age, or a schedule change—so they don’t capture the welfare-focused purpose of a humane endpoint.
