About this study

Official title: Comparison of FLT and FDG PET in the Evaluation of Response to Cetuximab, Cisplatin and Radiation Therapy in Advanced Head and Neck Malignancies or Response to Standard Chemo-radiotherapy in Esophageal Malignancies

RATIONALE: Diagnostic procedures, such as 3'-deoxy-3'-[18F] fluorothymidine (FLT) and fludeoxyglucose F 18 (FDG) PET scans, may help doctors predict a patient's response to treatment and help plan the best treatment.

PURPOSE: This pilot trial is studying FLT and FDG PET scans to see how well they evaluate response to cetuximab, cisplatin, and radiation therapy in patients with advanced cancer of the oropharynx, larynx, or hypopharynx.

Read the detailed description

OBJECTIVES:

Primary

  • To assess whether 3'-deoxy-3'-[18F] fluorothymidine (FLT) and fludeoxyglucose F 18 (FDG) PET scans can be used to identify patients with advanced squamous cell carcinoma of the oropharynx, larynx, or hypopharynx who have a biochemical response after 2 weeks of induction therapy with cetuximab.
  • To assess whether FLT and FDG PET imaging-based response after 20-30 Gy of radiotherapy is predictive of disease control at 6 months after completion of therapy.

Secondary

  • To assess whether FLT and FDG PET imaging-based response after cetuximab therapy and/or 20-30 Gy of radiotherapy is predictive of pathologic complete response in these patients.
  • To assess whether FLT and FDG PET imaging-based response after cetuximab therapy and/or 20-30 Gy of radiotherapy is predictive of disease-free survival at 2 years in these patients.
  • To correlate suppression of FLT uptake after cetuximab therapy with thymidine kinase 1 activity and/or expression, proliferation, microvessel density, apoptosis, and signaling pathway analyses.
  • To correlate suppression of FDG uptake after cetuximab therapy with expression of hexokinases, glucose transporter proliferation, microvessel density, apoptosis, and signaling pathway analyses.
  • To test and refine the ability of a novel commercial software package to quantify treatment-induced structural and functional/molecular volumetric and sub-volumetric change.
  • To develop a working method for expressing change and predicting outcome.

OUTLINE: Patients receive cetuximab IV on days 1 and 8 of course 1. Beginning in course 2 and all subsequent courses, patients receive cetuximab IV and cisplatin IV over 2 hours on day 1 and undergo radiotherapy once daily 5 days a week for 7 weeks. Treatment repeats every 7 days for a total of 8 courses in the absence of disease progression or unacceptable toxicity.

Patients undergo 3'-deoxy-3'-[18F] fluorothymidine and fludeoxyglucose F 18 (FDG) PET scans at baseline, after the second dose of cetuximab, after 20-30 Gy of radiotherapy, and then at 6 weeks and 6 months after completion of radiotherapy.

Patients undergo tumor tissue biopsies at baseline and after the first dose of cetuximab for correlative laboratory studies. Samples are analyzed for proliferation (Ki-67 labeling index), microvessel density (CD-31 staining), apoptosis (TUNEL assay and caspase-3 by IHC) signaling pathway (expression of EGFR, AKT, and MAPK by IHC), molecules affecting FDG uptake (expression of GLUT1, GLUT3, and hexokinase by IHC), and thymidine kinase 1 activity or expression.

After completion of study treatment, patients are followed every 3 months for up to 5 years.

What participants receive

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

What is being measured

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

  1. Percent change in the standard uptake value levels calculated for the identified volumes of interest for FLT and FDG PET scans from baseline to after 2 weeks of cetuximab therapy and from baseline to after 20-30 Gy of radiotherapy

Secondary outcomes (1)

  1. Quantified change values (after cetuximab therapy and after 20-30 Gy of radiotherapy) for the FLT and FDG PET scan-based topographic profiles created using the ImQuant software package

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing cetuximab, cisplatin and TdT-mediated dUTP nick end labeling assay in people with Head and Neck Cancer, run by Mayo Clinic 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?

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 31 Oct 2017. 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?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

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

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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 change in the standard uptake value levels calculated for the identified volumes of interest for FLT and FDG PET scans from baseline to after 2 weeks of cetuximab therapy and from baseline to after 20-30 Gy of radiotherapy. 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 NCT00757549.

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 31 Oct 2017; AzTrials last refreshed its copy on 7 Nov 2026.
