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 Calderasib, MK-3475A, or Placebo. The registry lists allocation as randomized. This is a phase 3, randomly assigned, neither you nor the study doctors know who gets the real treatment study of adjuvant calderasib plus subcutaneous pembrolizumab and berahyaluronidase alfa (MK-3475A) versus adjuvant dummy treatment (placebo) plus MK-3475a in participants with completely resected stage IIA-IIIB (N2), KRAS G12C-mutant non-small cell lung cancer following receipt of either neoadjuvant pembrolizumab plus chemotherapy or adjuvant chemotherapy.
They plan to enroll about 400 people at 122 sites. Taking part typically means taking a study drug (or dummy pill), an infusion or injection of a biologic plus check-ins.
