About this study

Official title: Judging MR Simulation Procedures: A Phase I-II Study of the Use of Magnetic Resonance Imaging Simulation in the Planning of Radiation Treatments

This is a master protocol for a prospective Phase I-II study evaluating feasibility and efficacy of incorporating magnetic resonance imaging (MRI) simulation into the planning of radiation treatments.

Read the detailed description

This is a Phase I/II clinical trial. A Phase I clinical trial tests the feasibility and safety of an investigational intervention. "Investigational" means that the process targeting high doses of radiation to the tumor based on MRI is still being studied. This research study is a Feasibility Study, which means it is the first-time investigators at this institution are examining this type of MR-guided dose planning. The U.S. Food and Drug Administration (FDA) has cleared MRI planning for use.

  • In Phase I of this study, will prospectively determine the feasibility of using an MRI simulator to plan radiation therapy.
  • In Phase II, the efficacy of adjusting RT based on MRI simulation will be explored, either by utilizing an MRI-simulation and synthetic CT to plan treatment or by dose-painting based on functional MRI data

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • MRI SimulatorDevice

    Radiation mapping to define the target for radiation.acquiring MR data at the specified timepoint in a patient's care plan and ability to identify the radiation target and develop a radiation therapy plan on the MR data.

  • Radiation TherapyRadiation

    In Phase I, radiation will be institutional standard per disease site. In Phase II, either radiation according to MR-based dose painting or adjusted RT. These adjusted doses and/or RT will vary per disease site and will be pre-specified in the subprotocols.

What is being measured

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

  1. Feasibility of acquiring MRI simulation prior to radiation therapy planning

    Feasibility is defined as successfully enrolling patients, successfully acquiring MR data at the specified timepoint in a patient's care plan and ability to identify the radiation target and develop a radiation therapy plan on the MR data

    Measured: 1 Year

  2. Proportion of patients with QOL decline exceeding 2 x MID

    12 points; MID of the EPIC-26 urinary irritative/obstructive domain is 6 points) measured by EPIC-26 urinary irritation/obstruction domain from baseline to 2 years

    Measured: baseline up to 24 months

Secondary outcomes (8)
  1. Number of Participants With Treatment-Related Adverse Events as Assessed by CTCAE v4.0

    Measured: 24 Months

  2. MRI evidence of disease at 2 years from treatment initiation.

    Measured: 24 Months

  3. PSA progression (nadir + 2) at 2 years from treatment initiation

    Measured: 24 months

  4. Progression free survival

    Measured: 24 months

  5. Change in target volumes between CT simulation and MRI simulation

    To ascertain the effects of MRI simulation on size of target volumes and OAR, the volume (cc) will be compared between CT vs MR simulation by t-test for normal data or Wilcoxon signed-rank test if data does not follow a normal distribution. The extent of overlap calculated with the Sorensen-Dice coefficient and Hausdorff distance.

    Measured: 24 Months

  6. Change in coverage of target volumes between CT simulation and MRI simulation

    The dose to OARS using the CT-simulation and MR-simulation derived plans will be compared using the t-test for normal data or Wilcoxon signed-rank test if data does not follow a normal distribution.

    Measured: 24 Months

  7. Change in dose to organs at risk (OARs) between CT simulation and MRI simulation

    The dose to OARS using the CT-simulation and MR-simulation derived plans will be compared using the t-test for normal data or Wilcoxon signed-rank test if data does not follow a normal distribution.

    Measured: 24 Months

  8. Performance of the synthetic CT in RT planning

    To assess performance of the synthetic CT in RT planning, fluence patterns from the synthetic CT plan will be copied onto the CT simulation electron density grids and dose recalculated. Accuracy of synthetic CT dose calculations to target volumes and OARs will be assessed with a goal of <1% difference in target and OAR dose between synthetic CT plans and CT simulation plans

    Measured: 24 Months
