IMaging Pilot Study of the αvβ6 Integrin Radiotracer [18F]-A20FMDV2 in PAtients With Solid Cancer Types

A substance called integrin alpha v beta six (αvβ6) is found to be increased in some cancer cells and can play an important role in the development and spread of cancer. If the levels of integrin αvβ6 in cancer cells can be measured by carrying out PET scans, we might be able to identify and potentially treat tumours. FBA-A20FMDV2 is a substance that binds or sticks to integrin αvβ6. It may therefore be possible to find and measure the amount of integrin αvβ6 in tumours. To do this a small amount of radioactivity will be attached to FBA-A20FMDV2 and carry out a scan called a Positron Emission Tomography (PET) scan. FBA-A20FMDV2 attached to radioactivity is known as \[18F\]FBA-A20FMDV2 or a radiotracer, as a very small amount of tracer dose is given to humans. So far such scans have been carried out in healthy volunteers and in patients with a lung condition called idiopathic pulmonary fibrosis (IPF). This was to assess the safety of the radiotracer and how it is taken up in the body. However, such scans have not been performed in cancer patients. This study will help specifically investigate αvβ6 in patients with cancer and find out how \[18F\]FBA-A20FMDV2 is taken up in tumours. With this information, the ideal imaging method for patients with cancer can be developed.
