Lutathera (lutetium (177Lu) oxodotreotide) is a cancer medicine for treating tumours in the gut known as gastroenteropancreatic neuroendocrine tumours (GEP‑NETs). It is a radiopharmaceutical (a medicine that emits a small amount of radioactivity). Lutathera is used to treat GEP-NETs that cannot be removed by surgery, have spread to other parts of the body or are not responding to treatment. Lutathera was designated an ‘orphan medicine’ (a medicine used in rare diseases) on 31 January 2008.

Lutathera is indicated for the treatment of unresectable or metastatic, progressive, well-differentiated (G1 and G2), somatostatin receptor-positive gastroenteropancreatic neuroendocrine tumours (GEP‑NETs) in adults.

The mechanism of action

Lutathera (lutetium 177Lu oxodotreotide) is a radiolabeled somatostatin analog. Lutathera binds to somatostatin receptors with the highest affinity for subtype 2 receptors (SSRT2). Upon binding to somatostatin receptor-expressing cells, including malignant somatostatin receptor-positive tumours, the compound is internalized.

The beta emission from Lu 177 induces cellular damage by the formation of free radicals in somatostatin receptor-positive cells and neighbouring cells.

Lutathera can help slow down the worsening of GEP‑NETs. In the main study of 229 patients with GEP‑NETs that contained somatostatin receptors, patients given Lutathera lived for an average of 28 months without their disease getting worse. This compares with around nine months for patients treated with octreotide, a medicine already approved for treating the condition.

Only a minority of patients with GEP‑NETs can be cured with surgery and at the time of diagnosis, the tumours would have spread in most patients. Lutathera can help slow the worsening of the condition and its side effects are considered manageable.

Side effects of Lutathera

The most common side effects seen with Lutathera treatment are nausea and vomiting, which occurred at the start of the infusions in around half of the patients and may be related to the amino acid infusion.
