The perils of surrogate endpoints [PDF]

open access: yesEuropean Heart Journal, 2015
Our goals in medicine are (i) to improve the quality of patients' lives, (ii) help them to live longer, and (iii) to do so at a reasonable cost. These are our true endpoints: health status, survival, and cost. It is thus entirely consistent with this point of view that these are the fundamental concepts that can be united in a formal cost–utility ...

Biomarkers and surrogate endpoints [PDF]

open access: yesBritish Journal of Clinical Pharmacology, 2005
When David Beckham leaves the field towards the end of a match, the man who replaces him is a surrogate. and although I suspect that many footballers, if asked, would say that Surrogate is a town in Yorkshire, the word actually comes from the Latin word subrogare, to substitute.

Defining Surrogate Endpoints for Clinical Trials in Severe Falciparum Malaria. [PDF]

open access: yesPLoS ONE, 2017
Clinical trials in severe falciparum malaria require a large sample size to detect clinically meaningful differences in mortality. This means few interventions can be evaluated at any time. Using a validated surrogate endpoint for mortality would provide

Evaluating Candidate Principal Surrogate Endpoints

open access: yesBiometrics, 2008
Summary Frangakis and Rubin (2002, Biometrics 58, 21–29) proposed a new definition of a surrogate endpoint (a “principal” surrogate) based on causal effects. We introduce an estimand for evaluating a principal surrogate, the causal effect predictiveness (CEP) surface, which quantifies how well causal treatment effects on the biomarker predict causal ...
