About this study

To evaluate the potential usefulness of 68Ga-DOTA-2P(FAPI)2 positron emission tomography/computed tomography (PET/CT) for the diagnosis of primary and metastatic lesions in various types of cancer, compared with 68Ga-DOTA-FAPI-46 PET/CT.

Read the detailed description

In order to enhance the tumor uptake and tumor retention time, we designed the dimer structure of fibroblast activation protein inhibitor (FAPI), a novel imaging agent that targeting cancer-associated fibroblasts expressed in various types of cancer, 68Ga-DOTA-2P(FAPI)2. Subjects with various types of cancer underwent contemporaneous 68Ga-DOTA-2P(FAPI)2 and 68Ga-DOTA-FAPI-46 PET/CT either for an initial assessment or for recurrence detection. Tumor uptake was quantified by the maximum standard uptake value (SUVmax). The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy of 68Ga-DOTA-FAPI-46 and 68Ga-DOTA-2P(FAPI)2 PET/CT were calculated and compared to evaluate the diagnostic efficacy.

What participants receive

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

  • 68Ga-DOTA-FAPI-46 and 68Ga-DOTA-2P(FAPI)2 PET/CTDiagnostic test

    Each subject receive a single intravenous injection of 68Ga-DOTA-FAPI-46 and 68Ga-DOTA-2P(FAPI)2, and undergo PET/CT imaging within the specified time.

What is being measured

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

  1. Standardized uptake value (SUV)

    Standardized uptake value (SUV) of 68Ga-DOTA-FAPI-46 / 68Ga-DOTA-2P(FAPI)2 for each primary tumor of subject or suspected lymph metastasis.

    Measured: 30 days

Secondary outcomes (6)
  1. Sensitivity

    The sensitivity of 68Ga-DOTA-FAPI-46 and 68Ga-DOTA-2P(FAPI)2 PET/CT

    Measured: 30 days

  2. Specificity

    The specificity of 68Ga-DOTA-FAPI-46 and 68Ga-DOTA-2P(FAPI)2 PET/CT

    Measured: 30 days

  3. The positive predictive value (PPV)

    The positive predictive value (PPV) of 68Ga-DOTA-FAPI-46 and 68Ga-DOTA-2P(FAPI)2 PET/CT

    Measured: 30 days

  4. The negative predictive value (NPV)

    The negative predictive value (NPV) of 68Ga-DOTA-FAPI-46 and 68Ga-DOTA-2P(FAPI)2 PET/CT

    Measured: 30 days

  5. The accuracy

    The accuracy of 68Ga-DOTA-FAPI-46 and 68Ga-DOTA-2P(FAPI)2 PET/CT

    Measured: 30 days

  6. Radiation Dosimetry

    Mean absorbed radiation doses were estimated using the source and target organ framework. Five patients with different cancers underwent serial 68Ga-DOTA-2P(FAPI)2 PET/CT scans at three time points following radiotracer injection: 10 minutes, 1 hour, and 3 hours. The source organs consisted of the kidneys, bladder, liver, heart, spleen, bone marrow, uterus, and body remainder. OLINDA/EXM software was used to fit and integrate the kinetic organ activity data to yield total body and organ time-integrated activity coefficients/residence times and finally organ absorbed doses.

    Measured: 30 days

Questions about this trial

What is this clinical trial studying?

A study testing 68Ga-DOTA-FAPI-46 and 68Ga-DOTA-2P(FAPI)2 PET/CT in people with Tumor, Solid, FAPI, PET/CT, Metastasis, run by The First Affiliated Hospital of Xiamen University at 1 site in China.

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 4 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: finished, as of the sponsor's last update on 8 Aug 2023. 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 China. 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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Standardized uptake value (SUV) (time frame: 30 days). 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 8 Aug 2023.
