Microbubble-enhanced transcranial focused ultrasound with temozolomide for patients with high-grade glioma (BT008NA): a multicentre, open-label, phase 1/2 trial.

ABSTRACT:

Background

Brain-infiltrating tumour cells from high-grade glioma remain shielded from drug treatments by the blood-brain barrier, leading to inevitable recurrence. Microbubble-enhanced transcranial focused ultrasound (MB-FUS) enables controlled blood-brain barrier opening (BBBO), permitting localised drug delivery. We aimed to assess safety and feasibility of MB-FUS plus standard-of-care chemotherapy for individuals with high-grade glioma.

Methods

BT008NA was an open-label, single-arm, phase 1/2 trial conducted at five sites in the USA and Canada (part of the ReFOCUSED Consortium). Key eligibility criteria were participants with newly diagnosed high-grade glioma (glioblastoma as per WHO 2016 classification), aged 18-80 years, with normal organ function, a baseline Karnofsky
