Abstract

Despite aggressive multimodal treatment, glioblastoma remains lethal, with inevitable recurrence and limited second line treatment options. In order to identify novel second line treatments, we developed a system of high-throughput screening in multicellular spheroids derived from 12 patient-derived glioma stem cell lines. We identified several cytotoxic candidates from a panel of 133 FDA approved anticancer compounds, of which actinomycin D was the most consistent across all cell lines. We subsequently validated the action of actinomycin D in patient-derived xenograft models of flank and orthotopic tumours in primary and recurrent glioblastoma. We finally demonstrate that actinomycin D works by downregulating Sox-2 (a transcription factor associated with stem cell function), thus identifying a potential drug and mechanism for treating recurrent glioblastoma
