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 Firmonertinib, or EGFR-TKI inhibitor based on investigator's choice. The registry lists allocation as randomized. Global, Phase 3, randomly assigned, multicenter, open-label study evaluating the how well it works and safety of firmonertinib at a dose level of 240 mg QD compared to investigator's choice of osimertinib (80 mg QD) or afatinib (40 mg QD) in participants who have locally advanced or metastatic NSCLC with EGFR PACC mutations, and who have not received any prior therapy for advanced disease.
They plan to enroll about 480 people at 141 sites. Taking part typically means taking a study drug (or dummy pill) plus check-ins.
Official title (unrewritten)
A Global, Phase 3, Randomized, Multicenter, Open-Label Study to Evaluate the Efficacy and Safety of Firmonertinib Compared With Investigator's Choice of Osimertinib or Afatinib as First-Line Treatment in Participants Who Have Locally Advanced or Metastatic Non-Small-Cell Lung Cancer With Epidermal Growth Factor Receptor P-Loop and Alpha C-Helix Compressing (PACC) Uncommon Mutations (ALPACCA)
Interventions: Firmonertinib, EGFR-TKI inhibitor based on investigator's choice
Primary outcome (registry wording): Progression Free Survival (PFS) determined by blinded independent central review (BICR)
