Glioblastoma multiforme (GBM) is the most malignant primary adult brain tumor.
The current standard of care is surgical resection, radiation, and chemotherapy
treatment, which extends life in most cases. Unfortunately, tumor recurrence is
nearly universal and patients with recurrent glioblastoma typically survive <1
year. Therefore, new therapies and therapeutic combinations need to be developed
that can be quickly approved for use in patients. However, in order to gain
approval, therapies need to be safe as well as effective. One possible means of
attaining rapid approval is repurposing FDA approved compounds for GBM therapy.
However, candidate compounds must be able to penetrate the blood-brain barrier
(BBB) and therefore a selection process has to be implemented to identify such
compounds that can eliminate GBM tumor expansion. We review here psychiatric and
non-psychiatric compounds that may be effective in GBM, as well as potential
drugs targeting cell death pathways. We also discuss the potential of data-driven
computational approaches to identify compounds that induce cell death in GBM
cells, enabled by large reference databases such as the Library of Integrated
Network Cell Signatures (LINCS). Finally, we argue that identifying pathways
dysregulated in GBM in a patient specific manner is essential for effective
repurposing in GBM and other gliomas.
