Mathematical Model-Adapted Radiation In Glioblastoma

Recurrent Glioblastoma Clinical Trial

Official title: Mathematical Model-Adapted Radiation Fractionation Schedule for Patients With Recurrent Glioblastoma (MARS-Glio)

Status Completed

Clinical Trial Summary

This research study is studying a new schedule of radiation therapy for recurrent glioblastoma as a possible treatment for this diagnosis. This radiation schedule is based on a new model for radiation resistance in glioblastoma.

The name of the radiation schedule involved in this study is:

• Re-irradiation for glioblastoma using a novel Mathematical Model-Adapted Radiation Fractionation Schedule

Clinical Trial Description

This research study is a Feasibility Study, which means that this is the first time that investigators are examining this new radiation schedule for recurrent glioblastoma.

• The FDA (the U.S. Food and Drug Administration) has approved radiation therapy as a treatment option for your disease.

• This is the first time that this particular radiation schedule will be tested in humans. There many other studies which have tested different radiation schedules in glioblastoma.

In this research study, investigators are adapting a standard two-week schedule of radiation commonly used for recurrent glioblastoma using a mathematical model. This study uses the same total dose of radiation as standard treatments but breaks up the dose into different amounts daily to maximize tumor kill. investigators have used a new mathematical model to create this schedule of radiation. This model was created to better represent how glioblastoma cells can escape the damaging effects of radiation. Based on the results of several laboratory studies, it is possible that this model may result in improved outcomes compared to standard radiation schedules.

The primary question of this study is to see whether participants can complete this new radiation schedule at the scheduled times. In addition, investigators will follow participants to ensure that this treatment is safe. If this treatment proves feasible, investigators hope to compare this treatment directly with standard radiation schedules for newly diagnosed and recurrent glioblastoma. ;
