Following publication of the original article [1], the authors want to clarify the wording of two sentences.

In the line of the study procedures section “In total, 44 patients will be enrolled per group. After n = 18 patients have been enrolled to the HYPO- or CON-treatment arm, respectively, an interim efficacy analysis for the respective arm will be conducted based on the objective response rate (ORR) at 12 weeks after first durvalumab administration”, the sentence was refined to “[…] the objective response rate (ORR), when the 18th patient in each arm has undergone first radiographic assessment (at 12 weeks after first durvalumab administration).”

In the study endpoint section, in the line “The ORR evaluated 12 weeks after first durvalumab administration (according to RECIST 1.1) is set as the primary efficacy endpoint.”, the sentence changed to “The ORR according to RECIST 1.1 is set as the primary efficacy endpoint.”
