Within the examine, patritumab deruxtecan demonstrated a statistically vital enchancment in PFS — the examine’s main endpoint — versus platinum plus pemetrexed induction chemotherapy.
As regards total survival, a key secondary endpoint of the examine, the info had been immature on the time of the evaluation. The examine will proceed to additional assess total survival.
