| ERBB4 mutant | lung squamous cell carcinoma | predicted - sensitive | Afatinib | Phase III | Actionable | In a Phase III trial (LUX-Lung 8), secondary analysis demonstrated favorable outcomes with Gilotrif (afatinib) treatment compared to Tarceva (erlotinib) in lung squamous cell carcinoma patients with ERBB (HER) family mutations, and ERBB4 (HER4) mutations predicted an OS (HR=0.22) and PFS (HR=0.21) benefit for Gilotrif (afatinib) over Tarceva (erlotinib) treatment (PMID: 29902295; NCT01523587). | 29902295 |
