NCT03778294

Brief Summary

This phase II trial studies how well fluorodopa F 18-positron emission tomography/magnetic resonance imaging scan (18F-DOPA-PET/MRI) works in imaging elderly patients with newly diagnosed grade IV malignant glioma or glioblastoma during planning for a short course of proton beam radiation therapy. 18F-DOPA is a chemical tracer that highlights certain cells during imaging. PET scan, is a metabolic imaging technique which takes advantage of how tumor cells take up nutrients differently than normal tissue. MRI scans are used to guide radiation therapy for most brain tumors. Hypofractionated proton beam therapy delivers higher doses of radiation therapy over a shorter period of time and may kill more tumor cells and have fewer side effects. Using 18FDOPA-PET scans along with MRI scans may be able to provide the radiation doctor with information on tumor tissue versus normal, healthy tissue and may help the doctor more accurately plan the radiation treatment.

Outcome Measures

Primary Outcomes (1)

  • Overall Survival (OS)

    The proportion of successes will be estimated by the number of successes divided by the total number of evaluable patients. Confidence intervals for the true success proportion will be calculated utilizing exact binomial methodology. The distribution of survival time will be estimated using the method of Kaplan-Meier (1958).

    Time from registration to death due to any cause, assessed up to 12 months

Secondary Outcomes (3)

  • Progression Free Survival

    At 12 months after radiation therapy

  • Progression Free Survival

    Up to 4 years

  • Incidence of Adverse Events (AEs)

    Up to 4 years

Other Outcomes (3)

  • Radiotherapy (RT) Treatment Volumes

    Up to 5 years post treatment

  • Quality of Life (QOL)

    Up to 5 years post treatment

  • Differences in Proton Radiation Planning

    Up to 5 years post treatment

Study Arms (1)

Treatment (18F-DOPA, PET/MRI, PET/CT, temozolomide)

EXPERIMENTAL

Patients receive 18F-DOPA IV and undergo PET/MRI or PET/CT imaging scan. Patients then receive proton beam radiotherapy over 5 or 10 consecutive days excluding weekend and standard of care temozolomide on days 1-7 or 1-14. Beginning cycles 2, patients receive standard of care temozolomide on days 1-5. Cycles with temozolomide repeat every 28 days for up to 7 cycles in the in the absence of disease progression or unacceptable toxicity.
