What participants receive

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

  • MRIdian LinacDevice

    Also called ViewRay

    Radiation therapy (RT) will be delivered with an integrated MRI-RT delivery system (MRIdian Linac). Participants will then receive standard-of-care RT with a dose prescription of 70 Gy in 35 fractions on the MRIdian Linac. Adaptive RT (ART) planning will occur every 5th fraction of RT.

Study groups in NCT05849142
Study groupRoleWhat they receive
MRIdian Linac GroupExperimentalAll accrued participants will be enrolled onto the MRIdian Linac Group. Participants will receive adaptive radiotherapy (ART) on the MRIdian Linac. Participants will complete the duration of their radiotherapy regimen on the MRIdian Linac for approximately 7 weeks.
Receives: Device: MRIdian Linac

What is being measured

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

  1. Percent difference between initial reference plan and adaptive weekly RT plan

    Weekly adaptive plans will be compared to the initial reference plan and compared using a percent difference equation estimating the actual values of the quantities used as dosimetric constraints for each participant between the initial reference plan and the weekly adaptive plan[s].

    Measured: Up to 6 months

  2. Evaluation of deformable imaging registration

    For evaluation of deformable imaging registration, deformed contours will be compared to the physician-segmented contours using the Dice similarity coefficient (DSC).

    Measured: Up to 6 months

Secondary outcomes (3)
  1. Treatment times recorded in minutes

    We will follow previously-established guidelines by the MR-Linac Consortium Head and Neck Tumor Site for measuring treatment times. Treatment times will be calculated in minutes from the time stamps in the record and verify system. Three timepoints will be recorded: [1] setup and plan optimization [i.e. time between the participant's arrival to the MRidian and delivery of the first beam]; [2] beam delivery [i.e. the time between delivery of the first and last beam]; and [3] total treatment time.

    Measured: Up to 6 months

  2. Patient-reported Quality of Life as measured by the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (QLQ) (EORTC QLQ-C30)

    Quality of life will be assessed using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30). It consists of 30 items to measure multiple aspects that incorporated five functional scales (physical, role, cognitive, emotional, and social), three symptom scales (fatigue, pain, and nausea/vomiting), a global health status/QoL scale, and six single common items (dyspnea, loss of appetite, insomnia, constipation, diarrhea, and financial difficulties). The scoring system ranged from 1 (not at all) to 4 (very much). High scores for functional items and low scores for symptoms represent the good QoL.There are two questions for the overall quality of life rating, and the ranking ranged from 1 (very poor) to 7 (excellent).

    Measured: Up to 1 year

  3. Patient-reported Quality of Life as measured by the European Organization for Research and Treatment Head & Neck 43

    Quality of life will be assessed using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-H\&N43). The questionnaire used will be for that for head and neck patients, score range from 1 (not at all) to 4 (very much), higher scores indicate lower quality of life.

    Measured: Up to 1 year

Timeline

From the start of the study to its completion; the mark is today. Estimated dates are the sponsor’s plan.

  1. First posted8 May 2023
  2. Study start1 Dec 2024 (estimated)
  3. Primary completion1 Dec 2024 (estimated)
  4. Study completion1 Dec 2024 (estimated)

Why it stopped: MRI Linac contract was not renewed at our institution after Viewray went bankrupt. Therefore we cannot do adaptive treatments on this machine. No patients were enrolled.

Questions about this trial

What is this clinical trial studying?

A study testing MRIdian Linac in people with Oropharynx Cancer, run by University of Miami 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 9 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: withdrawn, as of the sponsor's last update on 19 Sep 2024. 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?

The study was withdrawn before enrolling participants, so there are no results.

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?

Percent difference between initial reference plan and adaptive weekly RT plan (time frame: Up to 6 months). 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 19 Sep 2024.
