I think this is the perfect combination. The original phase 3 trial of tumor treating fields (TTF) for recurrent glioblastoma did not show a benefit because the patients were too far gone - TTFs are slow and gentle, and need a few months to turn the tide and shrink the tumor away. Most patients in the trial did not have the time for TTFs to work. GammaTile is implanted at the time of surgery, and slowly releases radiation to the tumor bed. It possibly could buy the time needed for the TTFs to kick in. I will keep an eye on this trial.
