PET/CT Molecular Imaging of Angiogenesis in Pulmonary or Head and Neck Cancers Prior to or During Chemotherapy Including Agent With Antiangiogenic Effect. A Prospective Multicentric Study of Efficacy and Tolerability.

The primary objective of this Phase II study is to evaluate the use of labelled RGD ligand in PET/CT to predict and/or to early assess the efficacy of chemotherapy including an agent with antiangiogenic effect.
The predictive value of this approach will be determined by independent assessors on basis of data at the end of the treatment: RECIST 1.1 criteria for CT or MRI, PERCIST criteria for FDG PET/CT, clinical, endoscopic and histological findings.

INTRODUCTIONRupture of unstable atherosclerotic plaque that leads to stroke and myocardial infarction may be induced by macrophage infiltration and neovessel formation. A tracer that selectively binds to integrin αvβ3 a protein expressed by macrophages and neovascular endothelium may identify rupture prone plaque.METHODS(18)F-labeled "R-G-D" containing tripeptide (Flotegatide), a click chemistry derived radiotracer that binds to integrin αvβ3 was injected in ApoE knockout mice fed a high fat diet. Uptake of Flotegatide by atherosclerotic plaque was visualized by micro-PET, autoradiography, and correlated to histologic markers of inflammation and angiogenesis.RESULTSWe found that Flotegatide preferentially binds to aortic plaque in an ApoE knockout mouse model of atherosclerosis. The tracer's uptake is strongly associated with presence of histologic markers for macrophage infiltration and integrin expression. There is a weaker but detectable association between Flotegatide uptake and presence of an immunohistochemical marker for neovascularization.DISCUSSIONWe hypothesize that Flotegatide may be a useful tracer for visualization of inflamed plaque in clinical subjects with atherosclerosis and may have potential for detecting vulnerable plaque.
