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 Trastuzumab Deruxtecan, pembrolizumab, or Pemetrexed. The registry lists allocation as randomized. This clinical trial is designed to assess the how well it works and safety of trastuzumab deruxtecan (T-DXd; Enhertu®) in combination with pembrolizumab versus platinum-based chemotherapy in combination with pembrolizumab in participants with no prior therapy for locally advanced unresectable or metastatic non-squamous NSCLC, whose tumors have HER2-overexpressing and PD-L1 TPS \<50% without known AGA that have locally available therapies targeting their AGAs in first-line advanced/metastatic setting.
They plan to enroll about 686 people at 246 sites. Taking part typically means taking a study drug (or dummy pill) plus check-ins.
