Abstract

Despite highly toxic treatments, head and neck squamous cell carcinoma (HNSCC) have poor outcomes. There is an unmet need for more effective, less toxic therapies. Repurposing of clinically-approved drugs, with known safety profiles, may provide a time- and cost-effective approach to address this need. We have developed the AcceleraTED platform to repurpose drugs for HNSCC treatment; using in vitro assays (cell viability, clonogenic survival, apoptosis) and in vivo models (xenograft tumors in NOD/SCID/gamma mice). Screening a library of clinically-approved drugs identified the anti-malarial agent quinacrine as a candidate, which significantly reduced viability in a concentration dependent ma..
