About this study

Official title: Hyperpolarized 13C MR Imaging of Lactate in Patients With Locally Advanced Cervical Cancer for Treatment With Definitive Chemoradiation Therapy

The purpose of this study is to image tumour lactate in study participants with locally advanced cervical cancer. Our hypothesis is that lactate content in cervical tumours, as measured by hyperpolarized 13C Magnetic Resonance (MR) imaging, will correlate with diffusion-weighted MRI and 18FDG-PET (fluorodeoxyglucose-positron emission tomography). Furthermore, lactate imaging will potentially provide additional and more specific information regarding the metabolic activity of cervical tumours, thereby identifying regions of radiation resistance and guiding radiation treatment and brachytherapy.

Read the detailed description

Patients with locally advanced cervical cancer can be offered definitive treatment with radiation therapy with concurrent chemotherapy for curative treatment. Brachytherapy is an essential part of this treatment, used to deliver high central doses after external beam radiation. Three-dimensional image-guided brachytherapy (3DIGBT) is gradually becoming the standard of care in many centres across the world. The use of Magnetic Resonance Imaging (MRI) or Computerized Tomography (CT) for planning helps ensure adequate coverage of tumours, minimizing doses to organs at risk. However, standard imaging modalities used in 3DIGBT typically include T2 and T1 weighted MRI sequences or CT scans and visualizing of the disease can often be challenging. Furthermore, it can be difficult to differentiate between active cervical cancer and fibrosis, leading to treatment of larger volumes when there is uncertainty (Akila contouring study).

High tumour lactate concentration has been linked to poor clinical outcomes in patients with solid tumours, including cervical cancers treated with radiation therapy [1, 2]. Three-dimensional imaging of tumour lactate in patients with locally advanced cervical cancers may be useful in identifying regions of radiation resistance and guiding treatment with chemoradiation and brachytherapy. The objective of this study is to image patients with locally advanced cervical cancer using hyperpolarized 13C MR imaging to obtain a measure of lactate levels in cervical tumours. Lactate images and measurements will be correlated with diffusion-weighted MRI, 18FDG-PET imaging and bioluminescence microscopy (BLI).

Up to ten participants with cervical cancer that are to receive radical treatment with radiation and possible concurrent cisplatin will be recruited for this study from Sunnybrook Health Sciences Centre (Sunnybrook). A snap-frozen biopsy of the tumour will be taken at the first clinic visit. Prior to treatment, baseline diffusion weighted MRI images and 18FDG-PET scans will be obtained. Hyperpolarized 13C MR imaging will be performed through the injection of 13C pyruvate and measurements of tumour lactate levels. Lactate levels will be correlated with measurements from bioluminescence microscopy. The images from hyperpolarized 13C MR imaging will also be compared to diffusion-weighted MR and 18FDG-PET images.

The purpose of this study is to image tumour lactate in study participants with locally advanced cervical cancer. Our hypothesis is that lactate content in cervical tumours, as measured by hyperpolarized 13C Magnetic Resonance (MR) imaging, will correlate with diffusion-weighted MRI and 18FDG-PET.

What participants receive

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

  • Hyperpolarized 13C-PyruvateDrug

    The new imaging method being tested is called Metabolic MRI, which provides pictures of the metabolism occurring within cancer cells. It also involves injection of a contrast agent, Hyperpolarized Pyruvate (13C) Injection, into the arm vein. The participants will be injected with the study drug at a dose of 0.43 ml/kg and then receive a MRI scan.

  • 18F-FDGDrug

    18F-FDG is a radiopharmaceutical used in medical imaging. The uptake of 18F-FDG by tissues is a marker for the tissue uptake of glucose, which is correlated with certain types of tissue metabolism, particularly in cancer cells. The participant will be injected with the study drug at a dose of 5 MBq/kg to a maximum of 500 MBq and then receive a PET scan.

Model description
Up to ten participants with newly diagnosed FIGO stage IB-IVA cervical cancer that are to receive definitive radiation with or without concurrent cisplatin, are to be recruited for this prospective single institutional study. Participants will receive a hyperpolarized carbon 13 MR spectroscopy and PET scan in addition to the standard imaging that is required for staging. A tumour biopsy will be obtained at the time of the initial clinic visit.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Hyperpolarized 13C-Pyruvate and 18F-FDG in people with Uterine Cervical Neoplasms, 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 3 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: stopped early, as of the sponsor's last update on 22 Sep 2022. 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 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.

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 was stopped early (reason given: Lack of participants). 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?

Time resolved, 3D 13C lactate images from subjects with cervical cancer. (time frame: 1 year). 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 22 Sep 2022.
