A Phase II Study of Pulse Reduced Dose Rate Radiation Therapy With Bevacizumab
- Registration Number
- NCT01743950
- Lead Sponsor
- University of Wisconsin, Madison
- Brief Summary
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.

- Primary Outcome Measures
Name Time Method Overall survival end of study, which will be an average of 12 months time of first dose of PDRD+ Bevacizumab until time of death
- Secondary Outcome Measures
Name Time Method Change in Mini Mental State Exam (MMSE) Score baseline and then approximately every 8 weeks for 18 months 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.
progression free survival at 3 months for bevacizumab exposed patients, at 6 and 12 months for all patients Progression free survival (PFS) will be defined as the time from the first study treatment to the first occurrence of disease progression or death.
Change in Participant Reported FACIT-F Score baseline and then approximately every 8 weeks for 18 months The Functional Assessment of Chronic Illness Therapy - Fatigue (FACIT-F) instrument is a 13-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 from 0-52 where higher scores indicate better quality of life. A score of less than 30 indicates severe fatigue.
Incidence of Late Toxicities from 90 days post radiotherapy until time of death Late toxicity that is likely attributable to re-irradiation or bevacizumab will be recorded.
Incidence of Adverse Events up to 30 days post last dose of bevacizumab 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.
Change in Participant Reported FACT-BR Score baseline and then approximately every 8 weeks for 18 months 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.
Change in Karnofsky Performance Status baseline and then approximately every 8 weeks for 18 months The Karnofsky Performance Status measures a cancer patient's ability to perform ordinary tasks. It is score from 0-100 where 0 means a person has died, less than 40 is various degrees of unable to care for oneself, 50-70 is unable to work but can care for personal needs with variable assistance, and 80-100 is able to carry on normal activity with variable symptoms of disease.
