About this study

Official title: Defining a Personalized Hypoxic Radiation Target Through Correlation of Functional F18-FAZA PET Imaging to Pimonidazole-stained 3D Whole-mounted Histological Specimen

This is a pilot study in the form of a prospective Phase II, single centre, single arm hypoxia study of oral tongue cancer with FAZA-PET imaging and pimonidazole targeted IHC of surgical specimens.

Read the detailed description

In head and neck cancer, areas of tumours with low oxygen supply (called tumour hypoxia) harbour cells that are resistant to radiation and are prone to metastasize. Modern radiotherapy techniques are precise enough to deliver radiation to these small areas and could be used to target these areas to receive higher doses of radiation than the rest of the tumour to overcome resistance. Hypoxia can be "seen" in the body using special imaging such as [F-18]-FAZA-PET ([F-18]-Fluoroazomycin arabinoside positron emission tomography) but it has not been tested as a method for creating radiation treatment targets. As part of regular pathology tumour tissue is sliced extremely thinly (<1/100th of a millimeter) and stained so that individual cells can be seen under a microscope. Immunohistochemistry (IHC) is a special type of "stain" that can specifically highlight hypoxic areas. This method is considered the most accurate way to inspect for the presence of hypoxia. There is not a specific staining target for hypoxia ordinarily, but when patients ingest a substance called pimonidazole hydrochloride (HCl) it builds up specifically in hypoxic areas and can be targeted for IHC staining. In this study participants with oral tongue cancer will have a [F-18]-FAZA-PET scan and take a single dose of oral pimonidazole-HCl before having surgery to remove their cancer. The whole tumour will be used to create microscope slides using very thin slices of the tumour. The slices will be stained using IHC to show where the pimonidazole has built up and digital scans of the slides will be made. The hypoxia seen on the FAZA-PET scan will be "matched" with hypoxia on the electronic slides to see if the FAZA truly shows where hypoxia is in tumours and if it could be used as a way to plan radiation treatments to deliver more radiation to just those areas.

Study groups in NCT03181035
Study groupRoleWhat they receive
FAZA and pimonidazoleExperimental(18)F-Fluoroazomycin arabinoside (FAZA) will be administered via intravenous injection at a dose of 5.2 MBq/kg with a minimum dose of 200 Megabecquerel (MBq) (5.4 Millicurie (mCi)) and a maximum dose of 600 MBq (16.2 mCi) prior to positron emission tomography (PET) imaging. A single dose of oral pimonidazole capsules at a dose of 0.5 g/m2, will be taken by participants 16-20 hours prior to tumor resection surgery.
Receives: Radiation: (18)F-Fluoroazomycin arabinoside; Drug: Pimonidazole

What is being measured

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

  1. Cellular hypoxia correlation

    The degree to which hypoxic signal measured by FAZA-PET imaging is correlated with true cellular hypoxia confirmed by immunohistochemical staining of pimonidazole using a 3D whole-mount approach

    Measured: 1 year

  2. Hypoxic reference standard

    A reference standard hypoxic radiation target will be defined through the correlation of functional F18-FAZA PET imaging to a pimonidazole-stained 3D whole mounted histological specimen.

    Measured: 1 year

Secondary outcomes (2)
  1. Registration quality

    The quality of registration will be assessed through measuring registration error of various automatic and semi-automatic co-registration techniques

    Measured: 1 year

  2. Textural feature comparison

    Potential relationships between textural features of MRI, PET-CT, and immunohistochemistry will be evaluated.

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing (18)F-Fluoroazomycin arabinoside and Pimonidazole in people with Tongue Cancer, run by Sunnybrook Health Sciences Centre at 1 site in Canada.

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 13 inclusion and 3 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: paused, as of the sponsor's last update on 12 Aug 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 Canada. 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 combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

Results are not available in the source record.

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?

Cellular hypoxia correlation (time frame: 1 year). 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 12 Aug 2024.
