Trial Outcomes & Findings for Dose Escalated MRSI Guided Radiation Therapy in Glioblastoma (NCT NCT02394665)

NCT ID: NCT02394665

Last Updated: 2017-01-05

Results Overview

The efficacy of 3D MRSI-guided, dose escalated radiation in newly diagnosed glioblastoma (GBM) patients as measured by overall survival (OS). Overall survival (OS) is defined as the time elapsed from the start of study treatment until death. Surviving patients (including patients lost to follow up) will be censored at the date of last contact.

PRIMARY outcome

Timeframe: Up to 2 years

Population: Data were not analyzed due to insufficient number of evaluable subjects. Only one subject enrolled who was later withdrawn by the Investigator prior to assignment to any treatment group or receiving any protocol therapy.

Overall survival (OS) is defined as the time elapsed from the start of study treatment until death. Surviving patients (including patients lost to follow up) will be censored at the date of last contact.

SECONDARY outcome

Timeframe: Up to 2 years

Population: Data were not analyzed due to insufficient number of evaluable subjects. Only one subject enrolled who was later withdrawn by the Investigator prior to assignment to any treatment group or receiving any protocol therapy.

Rate of progression-free survival in study participants. Progression-free survival (PFS) is defined as the time elapsed from the start of study treatment to the date of documented progression events. For progression-free patients (without progression events), PFS will be censored at the last date of documented PF status.

Change in quality of life during radiation and across the longitudinal progression-free interval compared to baseline. Change of quality of life will be assessed and scored via the FACT-Br behavioral questionnaire.

Patterns of Failure will be assessed by determining the number of failures that arise in-field compared to the number that arise out-of-field. In-field failure will be defined as those where greater than 80% of the recurrence volume was encompassed by the 95% prescription isodose line. In addition, we will also describe failures by three types: unifocal, multifocal and diffuse (multicentric including leptomeningeal dissemination).
