Time frame
Time from randomisation to the date of distant metastases or death. Assessed up to date of DCO (05Jan24) to a maximum of approximately 63 months

What was measured

Time from the date of randomisation until the first date of distant metastases or date of death in the absence of distant metastasis. Distant metastasis is defined as any new lesion that is detected on a scan that is anywhere other than lung or regional lymph node according to RECIST v1.1 or proven by biopsy
