Feasibility of Patient Treatment Compliance as Measured by Number of Participants Who Were at Least 80% Compliance With Assigned Administration Time

PRIMARY outcome

Timeframe: Through completion of follow-up (estimated to be 30 months)

Population: Data was not collected for this outcome measure. Duration of response was never listed as an objective in the protocol; however it was erroneously mentioned in the statistical analysis section of the protocol and therefore was listed as a primary outcome measure in error as well.

* Response and progression will be evaluated in this study using the updated response assessment criteria for high-grade gliomas: Response Assessment in Neuro-Oncology (RANO) working group guideline \[JCO 28(11): 1963-1972, 2010\]. * The duration of overall response is measured from the time measurement criteria are met for complete response (CR) or partial response (PR) (whichever is first recorded) until the first date that recurrent or progressive disease is objectively documented (taking as reference for progressive disease the smallest measurements recorded since the treatment started).

SECONDARY outcome

Timeframe: Baseline, beginning of each cycle (each cycle is 28 days), and 1 month after completion of treatment (up to 13 months, median length of treatment 6 cycles - each cycle is 28 days (full range 2-12 cycles))

Population: The number analyzed for each timepoint may be different from the overall number of participants analyzed if any participant did not complete the questionnaire at that time point.

7-item questionnaire measuring over the past 7 days. Answers range from 0=not at all to 4=very much. Total score range is 0-28. A higher score indicates a lower physical well-being quality of life.

SECONDARY outcome

Timeframe: Baseline, beginning of each cycle (each cycle is 28 days), and 1 month after completion of treatment (up to 13 months, median length of treatment 6 cycles - each cycle is 28 days (full range 2-12 cycles))

Population: The number analyzed for each timepoint may be different from the overall number of participants analyzed if any participant did not complete the questionnaire at that time point.

7-item questionnaire measuring over the past 7 days. Answers range from 0=not at all to 4=very much. Total score range 0-28. A higher score indicates a higher emotional well-being quality of life.

SECONDARY outcome

Timeframe: From start of treatment through 2 months after end of treatment (median length 100 days, full range 78-240 days)

Population: Actimetry data was only collected on 6 participants.

* The ActTrust Condor Instrument watches are wrist actimetry/accelerometers. Patients will wear an accelerometer on their wrist to measure activity level during the day and at night until two months after the end of treatment. * Circadian amplitude, refers to the difference between the highest and lowest points of a circadian rhythm over a 24-hour cycle, is typically measured in the units of the rhythm being quantified. * The circadian mean amplitude was calculated per day for each patient with the mean and standard deviation reported across all days for each individual patient.

SECONDARY outcome

Timeframe: From start of treatment through 2 months after end of treatment (median length 100 days, full range 78-240 days)

Population: Actimetry data was only collected on 6 participants.

* The ActTrust Condor Instrument watches are wrist actimetry/accelerometers. Patients will wear an accelerometer on their wrist to measure activity level during the day and at night until two months after the end of treatment. * Sleep regularity index (SRI) is the probability of being at rest, calculated per day for each patient. An SRI closer to 0 indicates irregular sleep patterns (i.e., more variable day to day), while values closer to 1 indicate regular sleep patterns. The SRI index scale is 0\~1. * The SRI was calculated per day for each patient with the mean and standard deviation reported across all days for each individual patient.
