About this study

Official title: Urinary and Serum VEGF and MMP Levels in Patients Receiving Radiation Therapy for Glioblastoma Multiforme: Prospective Determination of a Predictive Value for Recurrence

This study will collect blood and urine samples from patients undergoing radiation therapy for glioblastoma multiforme (a type of brain tumor) to investigate the effects of this treatment on blood cells and certain proteins. The information from this study may help scientists develop new tests to measure radiation exposure and find new ways to treat cancer with radiation, and help determine which kinds of patients or tumors respond better to radiation therapy. Two proteins of particular interest in this study and which may be involved in the recurrence of cancer are VEGF (vascular endothelial growth factor) and MMPs (matrix metalloproteinases).

Patients 18 years of age and older with glioblastoma multiforme who are receiving or will receive radiation therapy as part of their medical treatment may be eligible for this study. Candidates are screened with a history and physical examination, blood tests, and magnetic resonance imaging (MRI) of the brain.

Participants will have blood and urine samples collected before, during and after completion of their radiation treatment. Urine samples are collected in a cup and about 2 tablespoons of blood are withdrawn through a needle in a vein. Additional samples may be requested at different times during treatment and in the 3-year follow-up period.

Read the detailed description

BACKGROUND

  • Preliminary data generated from our pilot protocol 02-C-0064 suggests that the urinary VEGF and MMP level at the one month follow-up time point compared to the last on-treatment time point collection may be predictive of tumor recurrence at one year.
  • Note that this preliminary study included patients with all histologies.
  • In an ongoing effort to validate our results with a larger more homogeneous patient cohort we propose to prospectively study patients undergoing radiotherapy for GBM.

OBJECTIVES

-We will determine whether VEGF and MMP level measurements aid in predicting tumor recurrence at 1 year.

ELIGIBILITY

-Patients seen in the radiation oncology clinic will be asked to provide samples of blood and urine before, during and after their radiation treatment.

DESIGN

  • This protocol-provides a means of acquiring blood and urine samples from patients receiving radiation therapy for Glioblastoma multiforme (GBM).
  • Patients will be analyzed according to their Radiation Therapy Oncology Group (RTOG) recursive partitioning prognostic subgroups, which includes patient age, KPS, extent of resection and neurological function.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. To determine if an increase in urinary VEGF and MMP level, from the end of treatment to a patient's one-month follow-up examination following radiotherapy is predictive of one-year recurrence in patients with Glioblastoma multiforme

    Determine the whether VEGF and MMP level measurements aid in predicting tumor recurrence at 1 year.

    Measured: one year

Questions about this trial

What is this clinical trial studying?

An observational study of Glioblastoma Multiforme, run by National Cancer Institute (NCI) at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 5 Nov 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Rukayat O Salau ((240) 858-3712, rukayat.salau@nih.gov), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

To determine if an increase in urinary VEGF and MMP level, from the end of treatment to a patient's one-month follow-up examination following radiotherapy is predictive of one-year recurrence in patients with Glioblastoma multiforme (time frame: one year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Nov 2026.
