Participants with neither disease progression nor death were censored at the last date of the last tumor assessment that confirmed that their disease had not progressed. Participants who underwent surgical resection with curative intent without prior progression were censored at the date of surgery. PFS was analyzed on the basis of the tumor response assessments made by the IRC. Non-inferiority analysis that followed the general approach took into account all tumor assessments obtained during the primary study treatment phase, the post-study treatment phase and those obtained during the follow-up phase.
