A Phase II Study of Pulse Reduced Dose Rate Radiation Therapy With Bevacizumab

Phase 2TerminatedNCT01743950

University of Wisconsin, Madison49 enrolled

Overview

To determine the efficacy of Pulse Reduced Dose Rate (PRDR) radiation when given in 27 fraction over 5.5 weeks with concurrent bevacizumab followed by adjuvant bevacizumab until time of progression in patients with recurrent high grade gliomas (grade III and grade IV). Patients will be placed in 1 of 4 groups based on their histologic diagnosis and prior exposure to bevacizumab.

10mg/kg every 2weeks.

PRDRRADIATION

Daily dose of 2.0gy delivered in .2gy pulses for a total of 54gy over 5.5 weeks and 27 fractions. In the rare instance of the presence of extensive disease requiring essentially whole brain radiation, a total daily dose of 1.8 Gy delivered in .2 Gy pulses for 23 fractions to a total dose of 41.4 Gy will be utilized.

Outcomes

Primary Outcomes

Overall Survival

time of first dose of PRDR+ Bevacizumab until time of death

Time frame: estimated to be an average of 12 months (the estimated mean follow-up time)

Secondary Outcomes

Incidence of Adverse Events

time of first dose of PDRD+ Bevacizumab until time of death. All changes from baseline assessment will be recorded until 30 days post last dose of bevacizumab, assessed using the NCI CTCAE version 4.0 criteria.

Time frame: data collected up to 18 months

Incidence of Late Toxicities

Late toxicity that is likely attributable to re-irradiation or bevacizumab will be recorded.

Time frame: data collected up to 18 months

Progression Free Survival

Progression free survival (PFS) will be defined as the time from the first study treatment to the first occurrence of disease progression or death.

Time frame: estimated to be an average of 12 months (the estimated mean follow-up time)

Change in Mini Mental State Exam (MMSE) Score

The MMSE survey is a clinician facilitated instrument scored on a scale of 0-30 where scores of 0-17 indicate severe cognitive impairment, 18-23 indicate mild cognitive impairment, and 24-30 indicate no cognitive impairment.

Time frame: data collected baseline and then approximately every 2 months for 8 months (participants did not provide data after 8 months)

Change in Participant Reported FACT-BR Score

The Functional Assessment of Cancer Therapy - Brain (FACT-BR) instrument is a 50-item survey with each item scored on a 5 point likert scale where 0 is 'not at all' and 4 is 'very much'. The total possible range of scores is 0-200 where higher scores indicate higher quality of life.
