What is PRRT and how does it work?

Peptide Receptor Radionuclide Therapy (PRRT) uses a radiolabelled somatostatin analog that binds to receptors on tumour cells, combined with radioactive compounds, including 111Indium, 68Galiium, 90Yttrium, 177Lutetium, to deliver the killing effect of the radioactivity directly to the cell, avoiding destruction of healthy cells often found with external beam radiation.

  • Hypersensitivity to the active substance or to any of the excipients listed

pCODR Recommendation

Final Recommendation was issued on August 01, 2019  – Reimburse with clinical criteria and/or conditions* for treatment of adult patients with somatostatin receptor positive ( SSR+) midgut neuroendocrine tumours (NETs ) whose disease has progressed on a somatostatin analogue and is unresectable (see conditions )

pERC Final Recommendation

BC Cancer Protocol Summary

As of August 1, 2020, patients with midgut, GEP-NETs will now be eligible for treatment with LUTATHERA® [lutetium (177Lu) oxodotreotide]. This listing covers adult patients with somatostatin receptor-positive (SSR+) midgut NETs whose disease has progressed on a somatostatin analogue and is unresectable (not removable by surgery).

The Ontario funding criteria covers the treatment of adult patients with somatostatin receptor-positive (SSR+) midgut NETs whose disease has progressed on a somatostatin analogue and is unresectable (not treatable by surgery). Eligible patients include those with progressed SSR+ midgut (defined as jejunoileum and proximal in the NETTER-1 trial) NETs and good performance status.

Saskatchewan funding criteria:

Unresectable, well differentiated midgut* neuroendocrine tumors (NET) in patients who have experienced radiographic disease progression during somatostatin analog therapy (e.g., octreotide, lanreotide)

Lutathera (177Lu-dotatate) may be given for a maximum of 4 doses or until disease progression or unacceptable toxicity.

NETTER-1 Study

NETTER-1 Study –  Unmet need for long-term effective treatment of inoperable, gastro-entero-pancreatic neuroendocrine tumours (GEPNET).

This first Phase III trial compares 177Lu-DOTATATE with Octreotide (Sandostatin® LAR Depot) in patients with inoperable, progressive, somatostatin receptor positive midgut carcinoid tumours. 230 patients are divided into two groups of 115 each. The primary objective is to compare Progression Free Survival (PFS) between the groups. Secondary objectives are to compare Objective Response Rate, Overall Survival (OS), Time to Tumour Progression between groups, and to assess safety, tolerability and quality of life. 35 European and 15 U.S. sites are involved.
