About this study
Official title: Clinical Study of 99mTc-3PRGD2 SPECT/CT in Diagnosis and Efficacy Evaluation of Rheumatoid Arthritis
This is an open-label SPECT/CT (single photon emission computed tomography/computed tomography) study to investigate the diagnosis and efficacy evaluation performance of 99mTc-3PRGD2 in rheumatoid arthritis patients. A single dose of nearly 11.1 MBq/kg body weight of 99mTc-3PRGD2 (≤20µg 3PRGD2) will be intravenously injected into the patients. Visual and semiquantitative method will be used to assess the whole-body planar and lesions section SPECT/CT images. Adverse events will also be observed in the patients.
Read the detailed description
As a critical member of adhesion molecule integrin family and an important representative angiogenesis-related molecular, integrin αvβ3 is expressed at low levels on mature endothelial cells and normal cells, but it is overexpressed on the neovasculature endothelial cells, which has a high specificity and affinity in binding to the tri-peptide sequence of arginine-glycine-aspartic acid (RGD). Angiogenesis in the synovial membrane plays an important role in the pathogenesis of rheumatoid arthritis (RA). Therefore, radiolabeled RGD peptides can be used as molecular probe in radionuclide imaging to assess angiogenesis noninvasively in vitro and investigate the progress of RA, so as to achieve the goal of early diagnosis and efficacy evaluation for RA.
Accordingly, a variety of radiolabeled RGD peptides have been used as radiotracers targeting the integrin αvβ3 expression to assess angiogenesis in vitro for noninvasive imaging via PET (positron emission tomography) or SPECT (single photon emission computed tomography). Some radiolabeled cyclic RGD peptides, such as 18F-Galacto-RGD, 18F-AH111585 and 99mTc-NC100692, have been investigated into clinical trials. The results demonstrated that both radiotracers allowed the specific imaging of various types of tumors, and the tumor uptake correlated well with the expression of integrin αvβ3 in both animal models and patients. Recently, several RGD dimeric peptides with PEG linkers have been studied. The new types of RGD peptides showed much higher in vitro integrin αvβ3-binding affinity than the single RGD tri-peptide sequence, and importantly, they exhibited significantly increased tumor uptake and improved in vivo kinetics in animal models. As a representative, 99mTc-3PRGD2 could be easily prepared and exhibited excellent in vivo behaviors in animal models. No adverse reactions are observed in animal models to date.
99mTc-3PRGD2, a novel tracer targeting integrin αvβ3 receptor, was tried to use in some tumors in recent years. However, there are few studies of 99mTc-3PRGD2 in other diseases except for tumors, especially no relevant reports in rheumatoid arthritis. Therefore, the investigators expect to further expand the applications of 99mTc-3PRGD2 in other diseases and to provide new methods and thoughts of assessing the efficacy of anti-αvβ3 or anti-angiogenesis therapy in rheumatoid arthritis. Based on the investigators previous animal study of 99mTc-3PRGD2 in RA, the investigators have strong interests in clinical trials of 99mTc-3PRGD2. An open-label SPECT/CT study has been designed to investigate 99mTc-3PRGD2 SPECT/CT in diagnosis and efficacy evaluation of RA. A single dose of nearly 11.1MBq/kg body weight 99mTc-3PRGD2 (≤20µg 3PRGD2) will be intravenously injected into the patients. Visual and semiquantitative method will be used to assess the whole-body planar and lesions section SPECT/CT images. Adverse events will also be observed in the patients.

Questions about this trial
What is this clinical trial studying?
A Early Phase 1 study testing 99mTc-3PRGD2 in people with Rheumatoid Arthritis, run by First Affiliated Hospital of Fujian Medical 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 8 inclusion and 5 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 21 Sep 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.
What does this phase mean?
Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
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?
99mTc-3PRGD2 SPECT/CT scan (time frame: Two 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 NCT02723760, which also lists 3 linked publications.
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 21 Sep 2023.
