68Ga-BNOTA-PRGD2 PET/CT in Patients With Rheumatoid Arthritis

Status Recruiting

Clinical Trial Summary

This is an open-label positron emission tomography/computed tomography ( PET/CT) study to investigate the diagnostic performance and evaluation efficacy of 68Ga-BNOTA-PRGD2 in rheumatoid arthritis (RA) patients. A single dose of nearly 111 MBq 68Ga-BNOTA-PRGD2 (≤ 40 µg BNOTA-PRGD2) will be intravenously injected into patients with RA. Visual and semiquantitative method will be used to assess the PET/CT images. Whole body 18F-FDG PET/CT will be performed for comparison.

Clinical Trial Description

The Alpha(v)beta3 integrin, one of the most prominent members of integrin superfamily, is trans-membrane heterodimeric proteins which mediate cell-cell and cell-extracellular matrix adhesion. Integrin alpha(v)beta3 receptor plays an pivotal role in promoting, sustaining and regulating the angiogenesis and was identified as a marker of angiogenic vascular tissue. Cyclic arginine-glycine-aspartic acid (RGD) peptides was identified as a key integrin recognition motif which could strongly bind to integrin alpha(v)beta3 and inhibit new blood vessel formation. Animal study in antigen induced arthritis demonstrated that intra-articular administration of a cyclic RGD antagonist of alpha(v)beta3 leading to inhibition of cell infiltrate, synovial angiogenesis, pannus formation, cartilage erosions and even diminishing arthritis severity. For these properties, RGD peptide-based multimodality molecular probes have been developed for noninvasive imaging by targeting integrin alpha(v)beta3. And compared with 18F-FDG PET/CT, radiolabeled RGD imaging is a promising approach to visualize angiogenesis and provide a therapeutic target for anti-angiogenetic and anti-integrin therapy.

For the further interests in clinical translation of 68Ga-BNOTA-PRGD2, an open-label PET/CT study was designed to investigate the diagnostic performance and evaluation efficacy of 68Ga-BNOTA-PRGD2 in RA patients. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
