Initial US Approval
- 20131
Indications
Metastatic mEGFR NSCLC (1L):
- First-line treatment of patients with metastatic non-small cell lung cancer (NSCLC) whose tumors have non-resistant epidermal growth factor receptor (EGFR) mutations as detected by an FDA-approved test (1.1) Limitations of Use: Safety and efficacy of GILOTRIF were not established in patients whose tumors have resistant EGFR mutations.1
Metastatic Squamous NSCLC (2L):
- Treatment of patients with metastatic, squamous NSCLC progressing after platinum-based chemotherapy.1
Recommended Dose/Route
Afatinib 40 mg orally once daily at least 1 hour before or 2 hours after a meal until disease progression or no longer tolerated.1
Dose Reductions for Adverse Reactions
- If afatinib is withheld and resumed when the adverse reaction fully resolves, returns to baseline or improves to Grade 1, reinstitute at a reduced dose, ie, 10 mg per day less than the dose at which the adverse reaction occurred.1
Pivotal Studies
LUX-Lung 3 (NCT00949650)2
- Key Inclusion Criteria: Previously untreated patients with EGFR mutation-positive, metastatic [Stage IV and Stage IIIb with pleural and/or pericardial effusion as classified by the American Joint Commission on Cancer (AJCC, 6th edition)] NSCLC.1,2
- Treatment: Afatinib 40 mg orally once daily or intravenous Pemetrexed (500 mg/m2) plus cisplatin (75 mg/m2) once every 21 days for up to 6 cycles.1,2
LUX-Lung 8 (NCT01523587)3
- Key Inclusion Criteria: Patients With Advanced Squamous Cell Carcinoma of the Lung as Second-line Therapy Following First-line Platinum-based Chemotherapy1,3
- Treatment: Patients in the afatinib arm received oral afatinib 40 mg once daily. The dose could be escalated to 50 mg once daily in the absence of treatment-related adverse events (AEs) of more than grade.1,3
