What this phase means
Phase 3: this treatment already looked useful in smaller studies. Now it is tested in a large group, often against standard care or a dummy treatment, to see if it should be approved.
Phase labels are FDA/ICH categories applied to the registry Phase field. They are not a finding that this study succeeded.
What the registry says happens
If you join, the listed intervention(s) are Pembrolizumab, Cisplatin, or Carboplatin. The registry lists allocation as randomized. The goal of this study is to learn if people who receive intismeran autogene and pembrolizumab after surgery are cancer-free longer than people who receive dummy treatment (placebo) and pembrolizumab.
They plan to enroll about 680 people at 246 sites. Taking part typically means taking a study drug (or dummy pill), an infusion or injection of a biologic plus check-ins.
