Trial summary

PSMA is highly expressed on the cell surface of the microvasculature of several solid tumors, including clear cell renal cell carcinoma (ccRCC). This makes it a potentially imaging target for the detection of ccRCC. Read more about this study

About this study

Official title: A Pilot Comparison of 68Ga-P16-093 and 18F-FDG PET/CT Imaging in the Same Group of Clear Cell Renal Cell Carcinoma Patients

PSMA is highly expressed on the cell surface of the microvasculature of several solid tumors, including clear cell renal cell carcinoma (ccRCC). This makes it a potentially imaging target for the detection of ccRCC. This pilot study was designed to evaluate the diagnostic performance of 68Ga-P16-093, a novel radiopharmaceutical targeting PSMA, which was compared with 18F-FDG PET/CT in the same group of ccRCC patients.

Read the detailed description

Renal cell carcinoma (RCC) is the most common solid tumor within the kidney and accounts for approximately 3% of all malignancies in the world. Clear cell RCC (ccRCC) is the most common subtype and accounts for the majority of kidney cancer-related deaths. Importantly, pro-angiogenic factors (VEGF, PDGF) are strongly upregulated in clear cell RCC, leading to high vascularized tumors. Prostate-specific membrane antigen (PSMA), as known as folate hydrolase I or glutamate carboxypeptidase II, is overexpressed on the cells of prostatic adenocarcinoma. However, PSMA is also expressed by tumor cells or neovascular endothelial cells of various solid neoplasms, such as renal cell carcinoma. Therefore, PSMA may be an ideal target for the diagnosis of ccRCC. 68Ga-P16-093, a novel radiopharmaceutical targeting PSMA, with the urea fragment of a conjugate that employs the HBED-CC chelator for labeling with 68Ga(III). The HBED-based chelating ligand binds the 68Ga3+ ion with high affinity in a pseudo-octahedral N2O4 coordination sphere by its two phenolate O, two amino-acetate carboxylate O, and two amino N donor atoms. This pilot study was designed to evaluate the diagnostic performance of 68Ga-P16-093 in the same group of ccRCC patients, compared with 18F-FDG PET/CT.

What is being measured

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

  1. Diagnostic performance

    comparing the number of tumor detected by 68Ga-P16-093 and 18F-FDG PET/CT

    Measured: through study completion, an average of 1 year

Secondary outcomes (1)
  1. standardized uptake value (SUV) of tumor

    comparing the SUVmax of tumor derived from 68Ga-P16-093 and 18F-FDG PET/CT

    Measured: through study completion, an average of 1 year

Questions about this trial

What is this clinical trial studying?

A study testing 68Ga-P16-093 and 18F-FDG in people with Clear Cell Renal Cell Carcinoma, run by Peking Union Medical College Hospital 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 3 inclusion and 4 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 3 Nov 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 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?

Diagnostic performance (time frame: through study completion, an average of 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05432947, which also lists 1 linked publication.

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 3 Nov 2022.
