About this study

Official title: A Randomized Trial Comparing Two Forms of Immobilization of the Head for Fractioned Stereotactic Radiotherapy

Fractionated stereotactic radiotherapy (SRT) requires extremely precise and reproducible immobilization of the patient's head. This randomized study compares the efficacy of two commonly used forms of immobilization used for SRT.

Read the detailed description

PRIMARY OBJECTIVE:

  1. To compare the efficacy of two commonly used, generally accepted forms of immobilization for the treatment of lesions in the head with fractionated stereotactic radiotherapy. Specifically, this study will use the ExacTRAC kilovoltage imaging system to assess positioning accuracy for these two systems.

OUTLINE:

Two routinely used methods of immobilization, which differ in their approach to reproduce head position from day-to-day are the Gill-Thomas-Cosman (GTC)frame and the BrainLab thermoplastic mask. The GTC frame fixates on the patient upper detention and thus us in direct mechanical contact with the cranium. The BrainLab mask is a two-part masking system custom-fitted to the front and back of the participant's head. After patients sign an IRB-approved informed consent form, eligible participants are either randomized to either the GTC frame or the mask for their course of SRT. Participants are treated as per standard procedure; however, prior to each treatment, a set of digital kV images (ExacTrac, BrainLabAB, Germany) is taken. These images are fused with reference digitally constructed radiographs obtained from treatment planning CT to yield lateral, longitudinal, and vertical deviations of isocenter and head rotations about respective axes. The primary endpoint of the study is to compare the two systems with respect to mean and standard deviations (SDs) using the distance to isocenter measure.

What is being measured

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

  1. Distance From Ideal to Center of GTC Frame and BrainLab Thermoplastic Mask With Respect to Average and Variability

    This study uses the ExacTRAC imaging system to assess positioning of frame or mask during SRT. Images yield lateral, longitudinal, and vertical deviations of the isocenter as well as head rotations about respective axes.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing GTC frame, Thermoplastic facemask and Stereotactic radiation therapy in people with Patients Receiving Fractionated Stereotactic Radiotherapy and for Brain Tumors, run by Sidney Kimmel Comprehensive Cancer Center at Thomas Jefferson University 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 1 inclusion and 1 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 29 Nov 2016. 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.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 19 Aug 2013). 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?

Distance From Ideal to Center of GTC Frame and BrainLab Thermoplastic Mask With Respect to Average and Variability (time frame: Measurements taken during SRT). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00328510, which also lists 3 linked publications.

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 29 Nov 2016.
