Study groups in NCT02031237
Study groupRoleWhat they receive
Stereotactic Radiosurgery (SRS)Patients with brain metastases receiving single fraction Stereotactic Radiosurgery (SRS). This intervention is not assigned by the investigator. Treatment has been decided prior to study enrollment. MRI scans will be performed approximately 1-2 weeks prior to SRS, and 1-2 weeks and 1 month after SRS. The MRI scan will include a routine clinical MRI series.
Receives: Radiation: Single Fraction Stereotactic Radiosurgery (SRS); Device: Magnetic Resonance Imaging (MRI) Assessments
Whole Brain Radiation TherapyPatients with brain metastases receiving fractionated (spread out over time) Whole Brain Radiation Therapy (WBRT). This intervention is not assigned by the investigator. Treatment has been decided prior to study enrollment. MRI scans will be performed approximately 1-2 weeks prior to RT, at the end of RT and 1 month after RT. The MRI scan will include a routine clinical MRI series.
Receives: Radiation: Fractionated Whole Brain Radiation Therapy (WBRT); Device: Magnetic Resonance Imaging (MRI) Assessments
Stereotactic Radiation TherapyPatients with brain metastases receiving fractionated (spread out over time) Stereotactic Radiation Therapy (FSRT). This intervention is not assigned by the investigator. Treatment has been decided prior to study enrollment. MRI scans will be performed approximately 1-2 weeks prior to FSRT, during the last week of RT but before the last fraction and 1 month after RT. The MRI scan will include a routine clinical MRI series.
Receives: Radiation: Fractionated Stereotactic Radiation Therapy (FSRT); Device: Magnetic Resonance Imaging (MRI) Assessments

What is being measured

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

  1. Percentage of the Gross Tumor Volume With a BTB Opening of Ktrans > 0.005 Min-1

    Fifty metastatic lesions from 21 patients received WBRT and 14 lesions from 9 patients treated by SRS were analyzed. Permeability of BTB (Blood-Tumor-Barrier) was quantified by the transfer constant, Ktrans, derived from dynamic contrast enhanced (DCE)-MRI that were acquired pre, 1-2 weeks after starting, and 1-month post-radiotherapy. A percentage volume of the BM with Ktrans >0.005 min-1 (%Vall) was used to evaluate the extent of BTB opening pre-RT and subsequent changes after receiving radiotherapy. The 50 lesions, from the 21 patients treated with Whole Brain Radiation Therapy, were divided into two subgroups: low-leaky (%Vall <50%) and high-leaky, based upon pre-RT measurements. Of the 50 lesions, 7 were classified as low leaky and 43 were classified as high leaky. All 14 SRS lesions were classified as high leaky.

    Measured: Pre-Treatment, 1-2 Weeks Post Treatment (SRS), 1 Month Post Treatment

  2. Change in Magnitude and Regional Variability of Blood Tumor Barrier (BTB)/Blood Brain Barrier (BBB) Permeability (Per Minute) in Tumor, Tumor Margin, Normal Brain and Brain Metastases

    An in-house program, based on a general kinetic model, along with an MRI contrast agent, Gadopentetic Acid (Gd-DTPA), will be used to estimate vascular permeability (per minute).

    Measured: Week -2 to -1, End of Treatment (WBRT), 1-2 Weeks Post Treatment (SRS), 1 Month Post Treatment

Secondary outcomes (1)
  1. Change in Mean K^Trans During and After Radiation Therapy

    Effect of radiation dose on vascular permeability (per minute) of the Blood Tumor Barrier (BTB)/Blood Brain Barrier (BBB). Permeability of BTB was quantified by Ktrans.

    Measured: Pre-treatment and 1 Month Post Treatment

Questions about this trial

What is this clinical trial studying?

An observational study of Brain Metastases, run by University of Michigan Rogel Cancer Center 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 6 inclusion and 8 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: finished, as of the sponsor's last update on 26 Jul 2019. 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?

Yes. Results are posted in the registry (first posted 26 Jul 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percentage of the Gross Tumor Volume With a BTB Opening of Ktrans > 0.005 Min-1 (time frame: Pre-Treatment, 1-2 Weeks Post Treatment (SRS), 1 Month Post Treatment). The study lists 2 primary outcomes in all. 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 26 Jul 2019.
