Dose Escalation Trial of Re-irradiation in Good Prognosis Recurrent Glioblastoma

NCT02709226 · Status: COMPLETED · Phase: PHASE1 · Type: INTERVENTIONAL · Enrollment: 17

Summary

Background:

A glioblastoma is a tumor in the brain. It is treated with surgery, chemotherapy and radiation therapy. However, most people s tumors come back after therapy. When the tumor grows back, surgery or chemotherapy may not be possible or may no longer work. Repeat radiation therapy or re-irradiation, is an option for treating these tumors when they regrow.

Objective:

To find out the safety and highest tolerated dose of re-irradiation for people who have recurrent glioblastoma.

Eligibility:

People ages 18 50 who have glioblastoma that has been treated with radiation but has regrown.

Design:

Participants will be screened with:

Medical history

Physical exam

MRI of the brain: They will lie in a machine that takes pictures of the brain.

Participants will have baseline tests before they start therapy. These will include:

Blood tests

Neuropsychological tests: These test things like memory, attention, and thinking.

Quality of life questionnaire

Eye and hearing tests

Participants will get a CT of the brain prior to radiation start in order to plan the radiation treatment. Once the plan is completed, they will receive radiation once a day Monday Friday for a total of 10 17 treatments. They will lie on their back for about 10 minutes while they get the treatment.

Participants will be monitored for side effects.

After they finish treatment, participants will have visits 1, 2, and 3 months later. Then they will have them every 2 months for 3 years. These will include:

Medical history

Physical exam

Blood tests

MRI of the brain.

Quality of life questionnaire

Neuropsychological tests (at some visits)

After 3 years, participants will be contacted by phone each month.

Radiation

Radiation therapy will be administered daily Monday-Friday at NCI, ROB unless the treatment schedule requires amendment in the event of inclement weather or federal holidays. Radiation therapy dose will be administered as per on consecutive treatment days, 5 fractions per week via a linear accelerator using 6 MV photons or greater. Dose escalation is as follows: dose level 1 (DL1) 3.5 Gy x 10; dose level 2 (DL2) 3.5 Gy x 12; dose level 3 (DL3) 3.5 Gy x 14. If 2 DLTs are observed in the second dose level a step down dose of 3.0 Gy x 14 fractions will be tested. If 2 DLTs are observed in the third dose level a step down dose of 3.0 Gy x 17 fractions will be tested. The study will have 3 planned re-irradiation dose levels, with 1 to 6 patients per dose level using the 3+3 design to define the MTD. The number of patients may be increased to 9 total patients at the MTD ( provided no DLT) with a maximum of 21 evaluable patients enrolled.
