Neuroendocrine Cancer Clinical Trial – Lutetium-177 OPS-201 (Satoreotide)

What is Lutetium-177 OPS-201? This is a 'next generation' Peptide receptor radionuclide therapy (PRRT) or more specifically the radiopharmaceutical that binds to both activated and unactivated somatostatin receptors which are upregulated on these tumours. There is far higher binding via this mechanism than standard octreotate. The technical name of the radiopharmaceutical is Satoreotide tetraxetan lutetium-177 (author's note, I'm guessing but it could be a variant of Lanreotide). It was once named JR11. What's the difference to the current approved therapy? Conventional PRRT (e.g. Lutathera, Lu177 Dotatate) is based on a somatostatin receptor 'agonist' approach, whereas 177Lu Ops 201 Satoreotide is a receptor 'Antagonist'. The differences are quite technical but in the most layman terms , the antagonist has the capability of attaching (binding) to more receptors, including those in a…

Theranostics for Neuroendocrine Cancer – A Find and Destroy Mission

You may also see it conveyed as 'Theragnostics' and these terms are interchangeable. The basic aim of theranotistics is to find and then destroy the 'bad guys'. With Neuroendocrine Cancer, finding the tumours (the bad guys) can often be a challenge - they can be small and/or difficult to find - they are sometimes expert at camouflage. Moreover, once found, they can then be difficult to treat (destroy), as they can often prove resistant to conventional cancer drugs and many are inoperable due to sheer quantity, spread and positioning. When they are found and identified, it's also really helpful to know from the intelligence gathered, how successful the destroy…
