Pulsed low-dose rate re-irradiation for recurrent glioma

Official title: A Phase-2 Trial to Investigate the Use of Pulsed Low-dose Rate Re-irradiation for Recurrent Glioma (PULSAR)

Run by Centro di Riferimento Oncologico - Aviano · NCT06055517 · Data updated 2026-11-12

This study is testing a new way of giving radiation therapy to people with recurrent gliomas to see if it can help treat their condition safely while reducing side effects.

Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults aged 18 and older with a confirmed diagnosis of recurrent cerebral glioma who have completed prior radiation therapy at least six months before enrollment.

Probably not a fit

Patients who are currently pregnant, have leptomeningeal spread of disease, or are receiving concomitant chemotherapy may not benefit from this study.

What this trial studies

This study evaluates the use of pulsed low-dose rate radiotherapy (pLDRT) as a treatment option for patients with recurrent gliomas. The approach aims to minimize the risk of symptomatic radionecrosis while allowing for higher cumulative radiation doses beyond the conventional limit of 100 Gy. By leveraging the cellular hyper-radiosensitivity at low dose rates, the study seeks to determine the safety and efficacy of this innovative re-irradiation technique. Participants will receive pLDRT after having previously undergone radiation therapy at least six months prior.

Why it matters

Potential benefit: If successful, this treatment could provide a safer re-irradiation option for patients with recurrent gliomas, potentially improving their outcomes.

How similar studies have gone: While the use of pulsed low-dose rate radiotherapy is a novel approach, similar studies in other contexts have shown promise in reducing radiotoxicity.
