Head and neck squamous cell carcinoma (HNSCC) is a common and often devastating disease without curative treatment when advanced or recurrent. The aim of this study was to assess whether capsid-modified oncolytic adenoviruses have therapeutic efficacy in HNSCC low passage tumour cell cultures and if it could be further improved by combination with cetuximab, radiotherapy and chemotherapy. We investigated which adenoviral capsid modifications allow best gene transfer and cell killing of HNSCC substrates. Gene transfer was assessed using replication-deficient adenoviruses expressing luciferase. Cell killing was studied in vitro and in vivo using oncolytic adenoviruses, which kill tumour cell by viral replication. The most effective capsid-modified oncolytic adenoviruses were combined with HNSCC standard therapies and their efficacy was assessed in vitro as well as in vivo. Cell killing was assessed …
