Dose Escalated MRSI Guided Radiation Therapy in Glioblastoma

Phase II Study of Dose Escalated, Targeted Radiation Therapy Using 3D Magnetic Resonance Spectroscopy Imaging (MRSI) in Newly Diagnosed Glioblastoma

In summary, the overall prognosis of glioblastoma (GBM) patients remains poor. Although clinical gains have been achieved in the past, these have been modest, with a majority of patients succumbing to local disease progression within 2 years. New strategies for treatment need to be identified which enhance local control above the current treatment regimen in order to achieve further clinical gains in this disease. Favorable early experience with magnetic resonance spectroscopy imaging (MRSI) demonstrates that metabolic imaging can identify active tumor beyond standard MRI as well as high risk regions at risk for local failure. There is also clinical evidence that limited field dose escalation with either simultaneous integrated boost (SIB) or stereotactic radiosurgery (SRS) is feasible and safe. Coupling these findings provide the rationale for this proposed Phase II trial designed to define efficacy and toxicity of the novel treatment approach of whole brain volumetric 3D MRSI guided dose-escalated radiation therapy (RT) in newly diagnosed GBM patients.

Study Overview

• Status: Terminated
• Conditions: Glioblastoma
• Intervention / Treatment: Radiation: Intensity Modulated Radiation Therapy; Drug: Temozolomide; Behavioral: Functional Assessment of Cancer Therapy-Brain (FACT-Br); Radiation: Simultaneous Integrated Boost; Device: 3D MRSI; Radiation: Stereotactic Radiosurgery Boost

Detailed Description

This phase II study will investigate efficacy and safety of volumetric 3D MRSI-directed treatment for newly diagnosed GBM patients. This study will enroll 48 patients in order to obtain at least 40 patients receiving RT and temozolomide. Depending on the size and number of HTVs, a patient will receive either simultaneous integrated boost (SIB) with IMRT (Group 1) or SRS boost followed by IMRT 1 week later (Group 2). Duration of enrollment will be 2 years and minimum follow-up will be 2 years.

The duration of treatment and follow-up will occur as follows:

• Six weeks of RT with concurrent Temozolomide treatment;
• 3D MRSI at week 3 and at the end of RT;
• 28 day break;
• Adjuvant treatment with Temozolomide administered daily on days 1-5 of each cycle, for up to 12 cycles (one cycle = 28 days) which will include standard gadolinium enhanced MRI and 3D MRSI prior to cycle 1, 5, 9, and post cycle 12 of adjuvant Temozolomide;
• Active follow-up at least every three months for one year after the end of adjuvant Temozolomide treatment;
• After one year follow-up for survival will occur every three months for one year.

• Study Type: Interventional
• Enrollment (Actual): 1
• Phase: Phase 2

   • Acquired immune deficiency syndrome (AIDS) based upon current Centers for Disease Control and Prevention (CDC) definition or known HIV seropositivity. Note, however, that HIV testing is not required for entry into this protocol. The need to exclude patients with HIV/AIDS from this protocol is necessary because the treatments involved in this protocol may be significantly immunosuppressive.
   • Active connective tissue disorders, such as lupus or scleroderma, that in the opinion of the treating physician may put the patient at high risk for radiation toxicity
   • Other major medical illnesses or psychiatric impairments that in the investigator's opinion will prevent administration or completion of protocol therapy

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Rate of Overall Survival (OS) in Study Patients	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.	Up to 2 years

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Rate of Progression-Free Survival (PFS) in Study Patients	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.	Up to 2 years
Rate of Grade 3 or Higher Toxicity as a a Consequence of Study Therapy.	Rate of Grade 3 of Higher Toxicity in study participants as a consequence of study therapy.	2 years
Change in Quality of Life From Baseline in Study Participants	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.	Up to 2 years
Patterns of Failure in Study Participants Post-Protocol Therapy	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).	Up to 2 years
