The last sentence!
“INTRODUCTION We previously reported that gallium maltolate (GaM) monotherapy has a profound cytotoxic effect on glioblastoma (GBM) cells in vitro and in vivo. Recent in vitro data suggests that GaM may act as a radiosensitizer, which could dramatically change how brain tumors are treated. These findings prompted further investigation into the potential neurotoxic effects of GaM alone and in combination with radiation therapy (RT). METHODS Athymic rats were inoculated intracranially with treatment-resistant U87MG GBM cells. After tumor confirmation on MRI, animals received oral GaM 50mg/kg/day or vehicle. A pilot cohort received RT (21 Gy) 28 days later. MRI was performed on a 9.4T Bruker preclinical scanner using our custom acquisition protocol that included pre- and post-contrast anatomical T1 and T2 sequences, and DSC perfusion imaging. Longitudinal MR spectroscopy was collected from 2mm3 voxels placed in enhancing and non-enhancing areas. MRI studies were repeated every 10-14 days. Data was processed using Imaging Biometrics and Bruker Paravision analysis software, as well as custom-made MATLAB scripts. RESULTS Brain microvascular cells were unaffected by GaM therapy in vitro and in vivo. Advanced MRI biomarkers, such as fractional tumor burden maps, highlighted the cytotoxic effect of GaM on xenograft tumors but not on surrounding brain parenchyma. The addition of a subclinical RT dose did not alter these findings. Absence of necrosis-marking vinyl and lactate peaks on MR spectra, as well as histology, confirmed the safety profile of combination GaM+RT. Additionally, MR spectra of non-tumor brain following acute (14 days of GaM) were comparable to those of chronic (47 days of GaM) treatment, indicating no metabolic changes. Finally, absence of sensorimotor deficits provided further evidence of GaM’s safety. These results are being validated currently in a larger cohort of animals. CONCLUSION GaM therapy does not cause overt neurotoxicity and is associated with excellent quality of life.”

But what will the phase 1 show? The possibility of vouchers may interest some if they could be done by 2029 but “excellent quality of life” may create more of a buzz and maybe even a bidding war when the phase 1 results are published. Or then again it might not.
