简要总结
To compare overall survival (OS) in patients treated with pumitamig in combination with chemotherapy versus placebo plus chemotherapy in the intent-to-treat (ITT) set. To compare progression-free survival (PFS) in patients treated with pumitamig in combination with chemotherapy versus placebo plus chemotherapy as assessed by blinded independent central review (BICR) in the ITT set.
