Clinical Trial Summary

The objective of this study is to demonstrate the efficacy and response of novel Magnetic Resonance Imaging (MRI)-guided ultrasound stimulated microbubble treatment to enhance radiation effects in humans receiving external beam radiotherapy delivered using a LINAC (linear accelerator) radiation therapy device.


Clinical Trial Description

The approach uses relatively low-power ultrasound, operating with lower power levels than high intensity focused ultrasound and ultrasound-based hyperthermia techniques, delivered on the Sonalleve platform. The tumour will be sonicated before the radiation to enhance the effect of therapy. The technique is spatially targeted and stimulates microbubbles using low-power ultrasonic fields in the tumour location only. The primary aim is to evaluate tumour response to MRg-FUS + MB and radiation, as measured radiologically or clinically within the treated therapeutic target regions.The secondary aim of this research is to evaluate early and late effect profiles of MRI- guided ultrasound stimulated microbubble treatment and radiation in patients with inoperable breast/chest wall tumours or LABC at 1 day, 1 week, 2 weeks, 1 month, 3 months, 6 months and 1 year after treatment. ;
