About this study

Official title: A Pilot Study to Evaluate the Utility of Interim Digital PET/CT in Predicting Outcomes for Locally Advanced Oropharyngeal Cancer

This pilot trial studies how well interim digital positron emission tomography (PET)/computed tomography (CT) works in predicting outcomes in participants with oropharyngeal cancer that has spread from its original site of growth to nearby tissues or lymph nodes who are undergoing chemoradiation therapy. Diagnostic procedures, such as PET/CT may help measure a participant's response to treatment.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To evaluate the utility of early (i.e. during treatment) digital (d)PET as a diagnostic tool to predict local control 6 months after definitive chemoradiation for patients with locally advanced oropharyngeal carcinoma.

SECONDARY OBJECTIVES:

  1. To study the association between dynamic dPET parameters taken at early time points (i.e. during treatment) and complete response (CR) on PET after definitive chemoradiation.

II. To study the association between dynamic dPET parameters taken at early time points (i.e. during) treatment and 2 year LC after definitive chemoradiation.

III. To assess the ability of dynamic dPET compared to conventional PET or conventional-equivalent dPET reconstruction to identify tumor volumes with greater sensitivity at the time of before (dPET1), during (dPET2, dPET3) and after (dPET4, dPET5) chemoradiation.

OUTLINE:

Participants receive radiotracer injection and undergo dPET/CT over 20-75 minutes at baseline, during the 2nd and 4th week of radiotherapy, and 3 months after the completion of chemoradiation therapy.

What is being measured

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

  1. Quantitative assessments of digital positron emission tomography (dPET) characteristics generated at early time points during treatment

    For each of the promising dPET parameters identified in the primary analysis we will examine potential cut-points to be used to best predict 6-month response/non-response using receiver operating characteristic (ROC) methods. Here we will examine specificity, sensitivity, positive predictive value and negative predictive values for each promising parameter to allow for preliminary data to be generated to anticipate which parameters may warrant future study.

    Measured: Up to 2 years

Secondary outcomes (6)

  1. Tumor burden

    Will compare digital versus conventional PET. Comparison of PET parameters from the dPET or the conventional (c)PET will be visualized using scatterplots; agreement between the two methods will be summarized.

    Measured: Up to 2 years

  2. Response rate for each patient local control

    Will be defined as no evidence of disease at 6 months on physical and endoscopic exam for patient with a compete response on 3 month PET. Will be performed using Kaplan-Meier methods.

    Measured: At 2 years

  3. Progression-free survival (PFS)

    PFS will be performed using Kaplan-Meier methods.

    Measured: Up to 2 years

  4. Standard uptake volume (SUV) from digital/conventional PET

    Will assess SUV and will compare mean values for each interim dPET. The changes of dPET/cPET SUV over the study period will be visualized using longitudinal plot, summarized at each time point, and modeled using linear mixed model for repeated measures.

    Measured: At 3 months

  5. Metabolic tumor volume (MTV) from digital/conventional PET

    Will assess MTV and will compare mean values for each interim dPET. The changes of dPET/cPET MTV over the study period will be visualized using longitudinal plot, summarized at each time point, and modeled using linear mixed model for repeated measures.

    Measured: At 3 months

  6. Total lesion glycolysis (TLG) from digital/conventional PET

    Will calculate TLG based on MTV and SUV and will compare mean values for each interim dPET. The changes of dPET/cPET TLG over the study period will be visualized using longitudinal plot, summarized at each time point, and modeled using linear mixed model for repeated measures.

    Measured: At 3 months

Questions about this trial

What is this clinical trial studying?

A study testing Computed Tomography and Positron Emission Tomography in people with Oropharyngeal Squamous Cell Carcinoma and HPV Positive Oropharyngeal Squamous Cell Carcinoma, run by Ohio State University Comprehensive Cancer Center.

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 17 inclusion and 14 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 7 Aug 2019. Status can change between updates, so confirm with the study contact before making plans.

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?

Quantitative assessments of digital positron emission tomography (dPET) characteristics generated at early time points during treatment (time frame: Up to 2 years). 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 NCT03611205.

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 7 Aug 2019.
