Glioblastoma multiforme (GBM) is the most common aggressive and incurable brain cancer in adults, with a very dismal prognosis for patients [1]. Nucleic acid therapeutics, including siRNAs and miRNAs/antimiRs, are emerging highly promising molecules for the precise treatment of refractory aggressive GBM. However, the clinical use of oligonucle-otide-based therapies required development of precise and safe targeted cell delivery strategies. In the last decade, nucleic acid aptamers-synthetic RNA/DNA molecules acting as high affinity ligands - or antagonists of their selected target - have provided very promising carriers for therapeutic oligonucle-otides [2]. Here we describe a novel combinational approach to target GBM with multiple RNA-based therapeutics. We designed two conjugates containing two aptamers that bind to, and inhibit, the receptor tyrosine kinases, Axl and PDGFR^, as targeted carriers of therapeutic RNAs inhibiting two key players of GBM (STAT3 and miR-10b) [3]. We have demonstrated that both the conjugates hamper GBM cell growth and migration and effectively and specifically prevent patient-derived glioblastoma stem cell (GSC) function and expansion [4, 5]. MRI spectroscopy was used to prove the effectiveness of innovative drugs based on aptamers in vivo. Most importantly, we demonstrate the therapeutic efficacy of such molecules in vivo in patient-derived GBM models and we show that the developed chimeras synergise both in vitro and in vivo. Collectively our results highlight the potential of a smart, safe and clinically translatable combined regime for GBM, opening a new path in the treatment of this aggressive disease.
