Advanced MR Imaging as Predictor of Treatment Response in Newly Diagnosed Glioblastomas

Study Purpose

This clinical trial studies advanced MR imaging techniques in measuring early response of standard treatment may become predictors of long-term treatment response in patients with newly diagnosed glioblastomas.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Eligible Ages 18 Years and Over
Gender All
More Inclusion & Exclusion Criteria

Inclusion Criteria:

  • - Patients must have radiologically and histologically confirmed diagnosis of newly diagnosed glioblastoma.
  • - Patients must have measurable disease, defined as evident tumors with gadolinium enhancement on MRI that is measurable in at least one diameter.
  • - Life expectancy of greater than 3 months.
  • - Patients scheduled for standard therapy (6 weeks radiation treatment (RT) ~ 60 Gy, plus temozolomide 75 mg/m^2 during 6 week RT, and followed routine monthly temozolomide therapy) - Ability to understand and the willingness to sign a written informed consent document; all patients, or their legal guardians, must sign a written informed consent and Health Insurance Portability and Accountability Act (HIPAA) authorization in accordance with institutional guidelines.

Exclusion Criteria:

  • - Patients who underwent complete resection.
  • - Patients with no evidence of measurable disease after surgery.
  • - Patients who have had chemotherapy or radiotherapy.
  • - Patients who have any type of bioimplant activated by mechanical, electronic, or magnetic means (e.g., cochlear implants, pacemakers, neurostimulators, electronic infusion pumps, etc), because such devices may be displaced or malfunction.
  • - Patients who are pregnant or breast feeding; urine pregnancy test will be performed on women of child bearing potential.
- For patients who have undergone surgical resection prior to joining the study, in whom baseline magnetic resonance (MR) images exhibit enough signal degradation (due to susceptibility artifact in the region of the surgical bed) such that the data are uninterpretable will be excluded

Trial Details

Trial ID:

This trial id was obtained from, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

The disease, disorder, syndrome, illness, or injury that is being studied.

Adult Glioblastoma
Additional Details

The standard care of patients with glioblastoma is concomitant chemoradiation and adjuvant temozolomide. Allowing for assessment of tumor therapy prior to treatment completion is important to select patients most likely to benefit from alternative treatment option. Multimodal advanced MR imaging- contrast-enhanced T1 weighted imaging, diffusion-weighted imaging, chemical exchange saturation transfer imaging, and perfusion imaging on 3T enables quantitative assessment of treatment response. Quantifying changes in advanced MR imaging techniques would allow predict outcome for early and long-term treatment response and survival in glioblastomas.

Arms & Interventions


Other: MR imaging and standard treatment

Patients with glioblastoma undergo 3-Tesla magnetic resonance imaging to measure tumor protein content (using CEST-MRI), cellularity (using DW-MRI), and perfusion (using DCE-MRI and DSC-MRI with IV administration of gadolinium-containing contrast agent) at pre-CCRT; 4 weeks after completion of the CCRT; and every 2 or 3 months during the adjuvant temozolomide therapy.


Device: - 3 Tesla magnetic resonance imaging

High resolution structural imaging (contrast-enhanced T1-weighted image, T2-weighted image, Fluid-attenuated inversion recovery)

Device: - Chemical exchange saturation transfer MRI

Amide proton transfer-weighted image

Device: - Diffusion weighted MRI

diffusion-weighted image with b value 0, 1000, and 3000
