&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;&amp;#039;&amp;#039;&amp;#039;Surrogate endpoint&amp;#039;&amp;#039;&amp;#039; is a term used in [[clinical trials]] to refer to a [[biomarker]] or physical sign that is used as a substitute for a [[clinically meaningful endpoint]] that measures directly how a patient feels, functions, or survives. Changes induced by a therapy on a surrogate endpoint are expected to reflect changes in a clinically meaningful endpoint.&lt;br /&gt;
&lt;br /&gt;
== Definition ==&lt;br /&gt;
The [[Food and Drug Administration]] (FDA) defines a surrogate endpoint as &amp;quot;a laboratory measurement or physical sign that is used in therapeutic trials as a substitute for a clinically meaningful endpoint that is a direct measure of how a patient feels, functions, or survives and is expected to predict the effect of the therapy&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
== Use in clinical trials ==&lt;br /&gt;
Surrogate endpoints are used in clinical trials to decrease the time it takes to see the effects of a treatment. For example, in trials of [[cholesterol]]-lowering drugs, it would take many years to see a decrease in the number of [[heart attacks]] or [[strokes]]. Instead, the level of cholesterol in the blood is used as a surrogate endpoint.&lt;br /&gt;
&lt;br /&gt;
== Criticism ==&lt;br /&gt;
The use of surrogate endpoints has been criticized because they do not always accurately predict the clinical outcome. For example, a drug might lower cholesterol (the surrogate endpoint) but not actually reduce the number of heart attacks or strokes (the clinical outcome).&lt;br /&gt;
