Use of Pulsed Low-dose Rate Re-irradiation for Recurrent Glioma (PULSAR)

Study Purpose

Re-irradiation in gliomas is a therapeutic option at recurrence before of 2nd-line chemotherapy. The dose of re-irradiation with conventional fractionation is unfortunately limited by the risk of symptomatic radionecrosis that is significant for cumulative doses above 100 Gy. The use of unconventional low dose rate pulsed radiotherapy (pLDRT) can reduce the risk of radiotoxicity while taking advantage of the cellular hyper-radiosensitivity that occurs at low dose-rates. The present study therefore aims at evaluating whether the use of pLDRT in the re-irradiation of recurrences of gliomas allows maintaining a low risk of symptomatic radionecrosis even for cumulative doses greater than 100 Gy.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

No
Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

NCT06055517
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Arms & Interventions

Arms

Experimental: Pulsed low dose-rate radiotherapy (pLDRT)

Interventions

Radiation: - Pulsed low dose-rate radiotherapy (pLDRT)

Radiation treatment will be carried out with high-energy photons (6MV) using intensity modulated radiation therapy (IMRT) or volumetric arc radiation therapy (VMAT). The daily dose is 2 Gy, divided into 10 subfractions of 0.2 Gy spaced by 3 minutes. The cumulative dose will be individualized for each patient and can range from a minimum of 40 Gy to a maximum of 60 Gy.
