Lutetium-177 Dotatate

How it works

Docks on the somatostatin receptors of hormone-making gut tumors, delivering lutetium-177, whose beta rays damage them up close.

What it's made of

The same 8-amino-acid octreotate as gallium-68 dotatate, with its DOTA trap, but loaded with lutetium-177, which gives off beta radiation and damages the cell and its neighbors.

What it's for

Prescribed for

Gastroenteropancreatic neuroendocrine tumors with somatostatin receptors, in adults and from age 12.
