Imaging Undefined Stage

This phase I trial studies a new imaging technique called FAPi PET/CT to determine where and to which degree the FAPI tracer (68Ga-FAPi-46) accumulate in normal and cancer tissues in patients with non-prostate cancer. The research team also want to know whether what they see on PET/CT images represents the tumor tissue being excised from the patient's body. The research team is also interested to investigate another new imaging technique called PSMA PET/CT. Participants will be invited to undergo a second PET/CT scan, with the PSMA tracer (68Ga-PSMA-11). This is not required but just an option for volunteer patients. Patients can decide to have only the FAPI PET/CT scan. The PET/CT scanner combines the PET and the CT scanners into a single device. This device combines the anatomic (body structure) information provided by the CT scan with the metabolic information obtained from the PET scan. PET is an established imaging technique that utilizes small amounts of radioactivity attached to very minimal amounts of, in the case of this research, 68Ga-PSMA-11 and 68Ga-FAPi. Because some cancers take up 68Ga-PSMA-11 and/or 68Ga-FAPi it can be seen with PET. CT utilizes x-rays that traverse the body from the outside. CT images provide an exact outline of organs where it occurs in patient's body. FAP stands for Fibroblast Activation Protein. FAP is produced by cells that surround tumors. The function of FAP is not well understood but imaging studies have shown that FAP can be detected with FAPI PET/CT. Imaging FAP with FAPI PET/CT may in the future provide additional information about various cancers. PSMA stands for Prostate Specific Membrane Antigen. This name is incorrect as PSMA is also found in many other cancers. The function of PSMA is not well understood but imaging studies have shown that PSMA can be detected with PET in many non-prostate cancers. Imaging FAP with PET/CT may in the future provide additional information about various cancers.

Serial Imaging of the Novel Radiotracer [^18F] FLuorthanatrace ([^18F] FTT) by PET/CT

This phase I trial studies how well fluorine F 18 fluorthanatrace positron emission tomography (PET)/computed tomography (CT) works in patients with solid tumors. Fluorine F 18 fluorthanatrace is a radioactive tracer, a type of imaging agent that is labeled with a radioactive tag and injected into the body to help with imaging scans. PET/CT uses a scanner to make detailed, computerized pictures of areas inside the body. PET/CT with Fluorine F 18 fluorthanatrace may allow more tumor cells to be found in patients with ovarian, fallopian tube, or primary peritoneal cancer.

Early Assessment of Response to Immune Checkpoint Blockade Therapy Using 18F-FLT PET/CT

In the current study, advanced positron emission tomography/computed tomography (PET/CT) and positron emission tomography/magnetic resonance (PET/MR) imaging methods will be used to validate the hypothesis that participants receiving immune checkpoint blockade (ICB) therapy, who ultimately achieve clinical benefit, will show an increase, or "FLARE", in tumor FLT and/or FDG uptake from baseline, as seen after cycle#1 of treatment, and that after 2 cycles of treatment responders will have a decline in FLT and FDG uptake, in comparison to the participants classified as "non-responders".

Imaging of Solid Tumors Using 68Ga-FAP-2286

Brief Summary: This is a single arm prospective trial that evaluates the ability of a novel imaging agent gallium-68 labelled (68Ga-) FAP-2286 (68Ga-FAP-2286) to detect metastatic cancer in participants with solid tumors using 68Ga-FAP-2286 tracer. FAP-2286 is a peptidomimetic molecule that that binds to Fibroblast Activation Protein (FAP). FAP is a transmembrane protein expressed on cancer-associated fibroblasts, and has been shown to be present on a number of solid tumors.

Pragmatic Study on the Use of 68Ga-PSMA-617 PET/CT Imaging as a Standard of Care to Influence Clinical Management of Tumors Overexpressing PSMA.

This project aims to monitor the innocuity/safety profile of cyclotron-produced [68Ga]-PSMA-617 PET imaging in PSMA-expressing cancers. It is a single-site, pragmatic, non-randomized and open-label study, with no control group. Although prostate cancers constitute the usual recommended population for this PET modality, recent evidences suggest that most solid tumors express substantial amount of PSMA in their neovasculature. As such, all cancers (excluding non-solid cancers) will be eligible for [68Ga]-PSMA-617 PET imaging in this trial, for as long as their tumors express PSMA. This study also aims to instigate the use of [68Ga]-PSMA-617 in the routine standard-of-care for detection and follow-up of eligible cancers. FInally, this project seeks to gather information about the impact on patient management this novel PET modality will have over the current standard-of-care.

An Open-Label, Non-Randomized, Single-Center, Investigator-Initiated Trial to Determine the Safety, Dosimetry, and Preliminary Effectiveness of 177Lu-DOTA-EB-FAPI in Patients With Various Solid Tumors

Increased fibroblast activation protein expression is positively correlated with the aggressiveness of cancer. Radiolabeled fibroblast activation protein inhibitor therapy, also known as radioligand therapy has become a novel treatment for patients with refractory cancer and disease progression after multiple-lines treatment. However, a major problem in the therapeutic use of 177Lu-DOTA-FAPI has been its short half-life and fast rate of clearance. This study was designed to evaluate the safety and tolerabilityof a long-lasting radiolabeled fibroblast activation protein inhibitor 177Lu-DOTA-EB-FAPI in patients with various refractory solid tumors.

68Ga-FAPI-46 Positron Emission Tomography - Computerized Tomography for Molecular Assessment of Fibroblast Activation

Comparison of 68Ga-GPFAPI-04 and 18F-FDG PET/CT in Patients With Malignant Tumors

The investigators designed and synthesized a novel fibroblast activation protein (FAP) ligand (DOTA-GPFAPI-04) by assembling three functional moieties: a quinoline-based FAP inhibitor for specifically targeting FAP, a FAP substrate Gly-Pro as a linker for increasing the FAP protein interaction, and a 2,2',2",2‴-(1,4,7,10-tetraazacyclododecane-1,4,7,10-tetrayl)tetraacetic acid (DOTA) chelator for radiolabeling with different radionuclides. Molecular docking studies investigated the FAP targeting ability of DOTA-GPFAPI-04. DOTA-GPFAPI-04 was then radiolabeled with 68Ga to give 68Ga-DOTA-GPFAPI-04 for positron emission tomography (PET) imaging. The investigators found that the 68Ga-DOTA-GPFAPI-04 has high stability, targeted specificity, and longer retention time. The tumor-to-muscle (T/M) ratio for 68Ga-DOTA-GPFAPI-04 reached 9.15.

A Phase I Study: PET Imaging of Cancer Patients Using [18F] 4-L-Fluoroglutamine (2S,4R)

This is a Phase I study. This study is the first time that a new experimental drug called 18FFluoroglutamine, or F-Glutamine, is being used in people. F-Glutamine is a drug designed to be used with PET scanners that can 'see' where F-Glutamine goes in the body, after its injected. PET scanners are one of the kinds of scanners you normally find in a hospital radiology department. The researchers have found that tumors in animals absorb F-Glutamine. The researchers believe that scans with F-Glutamine might be able to find tumors in patients. This first in-human study is being done to see how long F-Glutamine lasts in the blood, when it is given to people in tiny amounts by an injection, and to see where F-Glutamine goes in the body. If the results of this trial are good, then the study doctors plan to use F-Glutamine in another trial to see if scans with F-Glutamine are better for finding tumors compared to the standard types of scans that doctors use.
