About this study

Official title: Biomarker-guided RAdiation-deferring Treatment in Younger GBM Patients (BRAid GBM) Pilot Study

This study will investigate whether rapid molecular testing of recurrent glioblastoma (GBM) can identify tumour biomarkers that may help guide treatment selection in younger people with IDH-wildtype GBM. Participants will be people under 55 years of age whose diagnosis is consistent with glioblastoma and who have undergone recent surgery or previously participated in the initial phase of the BRAid GBM study.

Tumour tissue will undergo rapid molecular testing to identify biomarkers that may predict response to specific targeted treatments. Treatment decisions will be informed by the molecular characteristics of each participant's tumour and available evidence for treatments associated with the identified biomarkers.

The study will assess the feasibility and safety of implementing rapid molecular testing across multiple Australian hospitals and whether this approach can provide timely information to support personalised treatment decisions. The study will also explore whether biomarker-guided treatment may provide alternatives to, or reduce the use of, radiotherapy in younger people with glioblastoma, with the potential to reduce long-term treatment-related effects on cognition and quality of life.

Approximately 110 patients will be screened and 12 participants will be recruited from participating hospitals across Australia.

Read the detailed description

The BRAid GBM study is evaluating a novel treatment approach for younger people (under 55 years of age) with glioblastoma (GBM), an aggressive form of brain cancer. Standard treatment for GBM generally involves surgery followed by radiotherapy and chemotherapy. Although this approach can help control the disease, radiotherapy can cause long-term effects on brain function, including difficulties with memory, thinking and concentration, which may significantly affect quality of life, work and family life.

A small proportion of glioblastomas harbour specific molecular alterations that may make the tumour susceptible to targeted therapies. These include alterations involving the BRAF and NTRK genes and deficiency of the mismatch repair (MMR) system. Targeted therapies directed at these molecular abnormalities have demonstrated clinical benefit in other cancers and, in some cases, in patients with brain tumours. The BRAid GBM study will investigate whether rapid molecular testing of tumour tissue obtained at surgery can identify these alterations and enable treatment to be selected according to the molecular characteristics of an individual's tumour.

Patients whose tumours harbour an actionable biomarker may receive a matched targeted therapy: plixorafenib for BRAF-altered tumours, larotrectinib for NTRK fusion-positive tumours, or cadonilimab for MMR-deficient tumours. Patients whose tumours do not demonstrate an eligible biomarker will proceed with standard treatment with radiotherapy and chemotherapy. This approach is intended to determine whether rapid molecular profiling can identify patients who may be suitable for an alternative treatment strategy while maintaining timely access to standard care when targeted treatment is not indicated.

Participants will undergo regular clinical assessments and MRI scans to monitor tumour response and disease progression, together with quality-of-life and cognitive assessments to evaluate the effects of treatment on neurological and functional outcomes. Blood and tumour samples will also be collected for translational research to investigate the biological characteristics of glioblastoma and factors that may influence treatment response or resistance.
