Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Squamous cell carcinoma of the nasopharynx, oral cavity, oropharynx or hypopharynx with palpable adenopathy in the neck. Biopsy proven within the last 90 days.
  • Squamous cell carcinoma of the larynx regardless of lymph node status. Biopsy proven within the last 90 days.

  • Receiving definitive radiation therapy at Wake Forest University with or without concurrent systematic therapy.
  • Participants must be able to provide study specific informed consent prior to study entry.

Who cannot join

  • Cancers of the head and neck other than those stated above. This would include squamous cell carcinoma of unknown primary.

About this study

Official title: Monitoring Blood Flow and Metabolic Activity in Malignant Tissue of Head and Neck Region Using the Lara Device

This study will investigate the ability of Lucerno Dynamics Lara sensor when placed on the palpable carotid artery (or femoral artery) to monitor blood flow following the injection of 18-FDG and to distinguish peak flow in tumor versus tissue uptake. Investigators will then assess if differences in tumor versus tissue correlates with tumor response.

Read the detailed description

Primary Objective: To determine if Lara sensors placed over the carotid and femoral arteries can measure the plasma activity of 18 F-fludeoxyglucose (18-FDG) at time of injection and determine if that peak activity in the artery can be distinguished from peak activity in malignant tissue to provide enough information to obtain the arterial input function.

Secondary Objective: To evaluate changes (baseline to post treatment) in tissue uptake at first pass (AUC and time to peak blood flow) and during the 60-minute period (metabolic activity) leading to the , positron emission tomography (PET) scan. This data is to be collected from the Lucerno Device placed over the carotid and femoral arteries monitoring 18 F-fludeoxyglucose (18-FDG) activity in blood and malignant tissue throughout the pre positron emission tomography (PET) scan period.

What participants receive

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

  • Lara ScanDevice

    Four (4) sensors will be placed prior to the injection of 18 F-fludeoxyglucose (18FDG) at the following sites: 7 cm above injection site; injection site; surface of palpable presumed malignant tissue; palpable carotid artery.

    Standard doses of 18-FDG will be injected per Department of Radiology protocols

    All injections will be evaluated to insure the total dose of 18-FDG has been injected. Injections resulting in moderate to severe extravasations, as interpreted by Lara software, will be segregated and evaluated on an individual basis.

    The sensors will remain in place for 60 minutes during the 18-FDG uptake period with the patient in a reclined chair.

    After the uptake time is complete, the sensors will be removed by the technologist and the participant will be released.

    The study team will then upload the sensor data to a personal computer in the treatment planning room where it will be coded and processed as a Lara scan.

  • PET/CT Scan - Pre-treatment and Post-treatmentDiagnostic test

    The PET/CT imaging will be conducted according to standard of care. The main alteration to process flow will be the addition of the Lucerno sensors just prior to the injection of the PET material.

What is being measured

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

  1. Percentage of Tests That Input Function (IF) Could Be Calculated

    If input function can be calculated on five (5) or more (out of 10) patients, then investigators will consider this a feasible procedure. Input function is calculated using time-activity curves (TAC) from the arterial blood flow detector and integrating the signal over time. Peak and minimum values of each of the four (4) Lara detector time-activity curves (TAC) will be recorded to determine a range of expected values and if they are different.

    Measured: At baseline

Secondary outcomes (2)
  1. Change in Areas Under the Curve (AUC) Measurements

    Investigators will use a repeated measures linear model with change in areas under the curve as the outcome and time from baseline and the baseline area under the curve as predictors. From the model investigators will report the estimated change at the post treatment Lara measurement. Participants should have three measurements of area under the curve (baseline, mid-treatment, 3-week measurement prior to PET scan).

    Measured: Baseline up to 120 days after completion of treatment

  2. Change in Time to Peak Arterial Blood Flow

    Investigators will use a repeated measures linear model with change in areas under the curve as the outcome and time from baseline and the baseline area under the curve as predictors. From the model investigators will report the estimated change at the post treatment Lara measurement. Participants should have three measurements of area under the curve (baseline, mid-treatment, 3-week measurement prior to PET scan).

    Measured: Baseline up to 120 days after completion of treatment

Questions about this trial

What is this clinical trial studying?

A study testing Lara Scan and PET/CT Scan - Pre-treatment and Post-treatment in people with Squamous Cell Carcinoma of Head and Neck, run by Wake Forest University Health Sciences.

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: withdrawn, as of the sponsor's last update on 29 Mar 2022. 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?

Percentage of Tests That Input Function (IF) Could Be Calculated (time frame: At baseline). 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 29 Mar 2022.
