Brief summary
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.
Detailed description
This study is testing a new approach to treat people with the most aggressive type of adult brain tumour, glioblastoma. It will determine whether a treatment called selective internal radiation therapy (SIRT) (also know as Transarterial Radioembolisation (TARE), or radioembolisation) is safe and effective in patients with recurrent or progressive glioblastoma. Small radioactive beads (SIR-Spheres®) are administered directly into the blood vessels that feed the tumour. This aims to selectively damage cancer cells and spare healthy tissue. PRECISE will investigate whether SIRT may reduce the volume of the tumour or slow its growth. Participants will undergo a detailed assessment to confirm they are suitable for the treatment. Those enrolled will have a planning procedure to map the blood vessels supplying the tumour, followed by SIRT treatment. Participants will also have scans and medical follow-ups after the procedure to monitor how they are going and whether the treatment is working. Safety of participants will be closely monitored by a team of specialist doctors. This study may represent the initial step towards a new treatment option for people with gliomas, who currently have very few alternatives once standard treatments have failed.
Interventions
Single administration of SIR-Spheres® on Day 1 with optional one-time retreatment if clinically indicated

Higher scores indicate better functioning/global health status on the functional and global health scales, whereas higher scores indicate worse symptom burden on the symptom scales. |
