To determine:
- the best confirmed overall response rate (ORR) with neratinib in patients with tumors with somatic human epidermal growth factor receptor mutation (EGFR, HER2, HER3) or EGFR gene amplification;
- the clinical benefit rate (CBR) of neratinib therapy, defined as the percentage of patients with complete response (CR) + partial response (PR) + stable disease (SD) ≥ 16 weeks from the Cycle 1 Day 1 (C1D1);
- progression-free survival (PFS), defined as the time from C1D1 to first date of recurrence, progression, or death due to any cause;
- duration of response (DOR) of neratinib therapy, defined as time from which measurement criteria are met for CR or PR until the first date of documented disease progression;
- overall survival (OS) for each cohort;
