a Prevalence of replication stress (RS) alterations grouped by the mechanism of increased RS: (i) alterations leading to loss of RB pathway regulation and premature G1- > S phase entry, and (ii) alterations associated with oncogene-induced replication stress. Tumors with at least one of these alterations were classified as RS-high; tumors with none of these alterations were classified as RS-low. b Progression-free survival among patients with RS-low tumors. c Progression-free survival among patients with RS-high-negative tumors. Unlike patients with RS-low tumors, there was no benefit of addition of berzosertib to gemcitabine among patients with RS-high tumors.
