Trial summary

The purpose of this study is to see if PET/CT scans that use a radioactive substance called [18F] fluorothymidine (FLT), can detect and monitor changes in the tumor. Radioactive substances are used with PET/CT scans to "see" cancer cells, and are also called radiotracers. Read more about this study

About this study

The purpose of this study is to see if PET/CT scans that use a radioactive substance called [18F] fluorothymidine (FLT), can detect and monitor changes in the tumor. Radioactive substances are used with PET/CT scans to "see" cancer cells, and are also called radiotracers. FLT is a new radiotracer that has been given to people in prior studies. FLT PET/CT is an experimental scan unlike FDG (fluorodeoxyglucose) PET scan which is a standard clinical scan and is commonly used. The investigators would like to know if there is any evidence of early treatment response by obtaining FLTPET/ CT scans before and after treatment.

Read the detailed description

This protocol is an "umbrella" or "companion" protocol to be used in conjunction with other protocols that are evaluating treatment response in solid or hematologic malignancies. The aim of this protocol is to determine if PET imaging with the proliferation marker 18FFLT can monitor changes in FLT uptake parameters, in particular changes in the standardized uptake value (SUV), within tumor target lesions.

Study groupRoleWhat they receive
Serial FLT PET ImagingExperimentalPatients will receive a target injection of up to 10 mCi of FLT. Optionally, dynamic PET imaging over a chosen index lesion (based on size and/or high FDG-avidity on preceding CT and/or FDG PET/CT scans done for clinical purpose such as staging), may be performed. Otherwise, static PET images are obtained at approximately 60 min (+15 min) post FLT injection. In general this "body" scan will cover at least the region from skull base to the upper thigh for extracranial malignancies; depending on the specific location, extremities maybe also be scanned (e.g., extremity sarcoma), or the scan may be restricted to the brain (e.g. glioma).
Receives: Radiation: [18F] FLT; Device: PET/CT scans

What is being measured

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

  1. change from pre- to posttreatment

    We will describe the distribution of the change and explore if it is associated with the findings of standard-of-care imaging such as FDG-PET or CT/MRI using rank based methods such as Spearman correlation and the signed-ranks test. In addition we will also explore the value of the change in the FLT metrics in predicting the clinical outcome using logistic regression (for response) and proportional hazards regression (for progression and survival).

    Measured: 4 years

Questions about this trial

What is this clinical trial studying?

A study testing [18F] FLT and PET/CT scans in people with Histologically-confirmed Malignancies, run by Memorial Sloan Kettering Cancer Center 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?

The sponsor lists 3 inclusion and 2 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 17 Sep 2019. 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.

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?

change from pre- to posttreatment (time frame: 4 years). 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 17 Sep 2019.
