Overview

abstract

  • BACKGROUND: The human papillomavirus (HPV) E6 oncoprotein enhances the oncogenic potential of ErbB proteins in HPV-related malignancies. This phase I study evaluates the addition of afatinib, an ErbB family inhibitor, and ribavirin to paclitaxel and carboplatin induction chemotherapy in HPV-associated, locally advanced oropharyngeal squamous cell carcinoma (SCC). METHODS: This dose escalation study included 2 doses of oral afatinib: 30 and 40 mg daily. Ribavirin dosing was weight based. Paclitaxel (80 mg/m2 ) and carboplatin (area under the curve [AUC] 1.5) were administered on days 1 and 8 of each 21-day cycle. After 3 cycles, patients were removed from protocol to receive definitive treatment. RESULTS: Among 10 patients, there were no dose-limiting toxicities. Six patients (67%) had unconfirmed objective partial responses. The 2-year progression-free survival rate was 75%. CONCLUSION: Afatinib, ribavirin, paclitaxel, and carboplatin induction chemotherapy is safe and well tolerated. The phase II recommended dose of afatinib is 40 mg oral daily in this combination regimen.
