Prospective Exploratory Study of FAPi PET/CT With Histopathology Validation in Patients With Various Cancers

Study Purpose

This exploratory study investigates how an imaging technique called 68Ga-FAPi-46 PET/CT can determine where and to which degree the FAPI tracer (68Ga-FAPi-46) accumulates in normal and cancer tissues in patients with cancer. Because some cancers take up 68Ga-FAPi-46 it can be seen with PET. FAP stands for Fibroblast Activation Protein. FAP is produced by cells that surround tumors (cancer associated fibroblasts). 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.

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

No
Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

NCT04459273
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

PRIMARY OBJECTIVE:

  • I. To define the biodistribution of gallium Ga 68 fibroblast activation protein inhibitor (FAPi)-46 (68Ga-FAPi-46) in normal and cancer tissues of patients with various malignancies.
SECONDARY OBJECTIVES:
  • I. To evaluate the degree of 68Ga-FAPi-46 accumulation observed by positron emission tomography (PET) imaging as opposed to the amount of FAP in excised cancer tissue.
  • II. To assess the 68Ga-FAPI-46 biodistribution correlation with 18F-FDG biodistribution and to define the frequency of the following phenotypes (FAP+/ FDG+, FAP-/ FDG+, FAP+/ FDG-, FAP-/ FDG-) EXPERIMENTAL OBJECTIVE: To assess the correlation of 68Ga-FAPI-46 biodistribution with 68Ga-DOTATATE or 18F-DOPA (FDOPA), depending on the specific indication in patients who had them available.
OUTLINE: Patients receive 68Ga-FAPi-46 intravenously (IV), and then undergo PET/computed tomography (CT) over 20-90 minutes. On another day, patients receive 18F-FDG and then undergo PET/computed tomography (CT) according to standard of care procedures (if applicable).
