WebSep 7, 2024 · The surrogate threshold effect (STE) is defined as the minimum treatment effect on a surrogate that is reliably predictive of a treatment effect on the clinical outcome. It provides a framework for implementing a clinical trial with a surrogate endpoint. WebSurrogate threshold effect was equal to 1.29, i.e., observing 29% increase in mean PFS time would predict a significant increase of the OS time. In the subgroup of patients with measurable disease in the 2 nd round dataset (4,866 patients), R trial was higher and equal to 0.93 (95%CI = 0.70 to 1.00), with STE equal to 1.21.
