Current challenges and clinical investigations of epidermal growth factor receptor (EGFR)- and ErbB family-targeted agents in the treatment of head and neck squamous cell carcinoma (HNSCC).

Cancer treatment reviews •

Overexpression of the epidermal growth factor receptor (EGFR) is a common characteristic of head and neck squamous cell carcinomas (HNSCC). Cetuximab is a chimeric anti-EGFR monoclonal antibody (mAb) with multiple approved indications in HNSCC, including with radiation therapy (RT) for locoregionally advanced disease, as monotherapy after platinum progression, and with platinum/5-fluorouracil for recurrent or metastatic disease. There remain, however, numerous unanswered questions regarding the optimal use of cetuximab in HNSCC, including patient selection, its mechanisms of action and resistance, the effect of human papillomavirus status on outcomes, its role when combined with induction chemotherapy or adjuvant radiation, and optimal management of skin toxicity and hypersensitivity reactions. In addition, a variety of other anti-EGFR agents (the multitargeted small molecule tyrosine kinase inhibitors [TKIs] lapatinib, dacomitinib, and afatinib and the anti-EGFR mAbs zalutumumab, nimotuzumab, and panitumumab) are currently under investigation in phase II and III clinical trials in different HNSCC therapeutic settings. The anti-EGFR TKI erlotinib is currently in phase III development for oral cancer prevention. Numerous other drugs are in earlier stages of development for HNSCC treatment, including novel anti-EGFR mAbs (MEHD7945A, necitumumab, and RO5083945), small-molecule TKIs (vandetanib, icotinib, and CUDC-101), EGFR antisense, various add-on therapies to radiation and chemotherapy (bevacizumab, interleukin-12, lenalidomide, alisertib, and VTX-2337), and drugs (temsirolimus, everolimus, OSI-906, dasatinib, and PX-866) intended to overcome resistance to anti-EGFR agents. Overall, a wealth of clinical trial data is expected in the coming years, with the potential to modify significantly the approach to anti-EGFR therapy for HNSCC.

A phase 2 study of cetuximab in combination with docetaxel in chemotherapy-refractory/resistant patients with advanced nonsmall cell lung cancer.

Cetuximab in combination with docetaxel was examined in chemotherapy-refractory/resistant patients with advanced nonsmall-cell lung cancer (NSCLC) to determine response rate, survival, safety, and pharmacokinetics (PK). Patients had evidence of epidermal growth factor receptor (EGFR) expression (> or =1 +) and tumor progression during or disease recurrence within 3 months after chemotherapy. Cetuximab was administered weekly (400 mg/m(2) initial; 250 mg/m(2) thereafter). Docetaxel was administered every 3 weeks (75 mg/m(2)). A response in 3 of the first 21 patients was required to continue accrual to the target sample size of 50 patients. Confirmed responses included 1 complete response (1.8%), 10 partial responses (18.2%), and 20 with stable disease (36.4%). The response rate was 20% (95% confidence interval [CI], 10.4% to 33.0%) and median time to disease progression was 104 days. There were no differences in PK parameters of docetaxel alone or with cetuximab. The most common grade 3 of 4 adverse events were leukopenia (27.3%) and acne (21.8%). Four patients (7.3%) discontinued due to allergic reaction. The median overall survival (OS) was 7.5 months with a 1-year survival of 35%. Cetuximab in combination with docetaxel was well tolerated. The response rate supports more definitive evaluation of this combination in the second-line setting.
