About this trial
This study is testing a new way of treating brain tumours using tiny radioactive beads called SIR-Spheres® (90Y-labelled Resin Microspheres). These microspheres are placed into the blood vessels that feed the tumour. The treatment gives off radiation inside the tumour to try to stop it from growing.
This type of treatment is called Selective Internal Radiation Therapy (SIRT), Transarterial Radioembolisation (TARE), or radioembolisation. It is already an accepted treatment for patients with liver cancer. In this study, we are testing if this treatment can be done safely in the brain and how well it works.

Treatment groups
Trial outcomes
Primary outcomes
Safety - Treatment-related adverse events
Rate of any treatment-related adverse events within the first 30 days after TARE, according to CTCAE, version 6.0.
Safety - Severe treatment-related adverse events
Rate of any severe treatment-related adverse events (grade ≥3-5) within the first 30 days after TARE, according to CTCAE version 6.0
30-day mortality
Rate of all-cause mortality within 30 days following TARE.
Secondary outcomes
Technical success of TARE
Technical success rate, defined as successful selective catheterisation and administration of SIR-Spheres® to the target volume without significant non-target deposition.
Confirmation of dose delivery
Confirmation of dose delivery to the target volume as assessed by post-treatment PET/CT.
Objective response rate (ORR)
Objective response rate (ORR) according to RANO 2.0 and PET RANO 1.0 criteria.
Disease control rate (DCR)
Disease control rate (DCR) according to RANO 2.0 and PET RANO 1.0 criteria.
Other outcomes
To evaluate the correlation between organ at risk radiation dosimetry and adverse events
Correlation between absorbed dose (Gy) to normal brain, as estimated on post-treatment 90Y PET, and the incidence of treatment-related adverse events, as classified by CTCAE version 6.0
To evaluate the concordance between pre-treatment predicted and post-treatment delivered absorbed dose distributions to tumour and normal brain using voxel-based dosimetry
Correlation between absorbed dose estimates to tumour and normal brain derived from pre-treatment \[99mTc\]Tc-MAA SPECT/CT and post-treatment 90Y PET dosimetry
To investigate circulating biomarkers and potential mechanisms of resistance, for patients treated with this approach.
Change in circulating biomarker levels from baseline over time, including the identification of molecular or cellular markers associated with treatment response or resistance.
