Objective Endpoints

What are objective endpoints? Objective endpoints are measurable outcomes of a clinical trial and do not consider the subject’s feelings. Objective endpoints can be clinical endpoints, such as survival and risk, or non-clinical endpoints, such as blood tests. Objective endpoints are less vulnerable to bias.

What are the disadvantages of objective endpoints? 

Objective endpoints, especially non-clinical endpoints, require testing, which may be time- sensitive, expensive, and have the risk of laboratory errors.
