Peptide Receptor Radionuclide Therapy (PRRT)

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.

Lutetium Lu 177 dotatate (Lutathera)

LUTATHERA® (lutetium Lu 177 dotatate) – PRODUCT MONOGRAPH
Brand Name Lutathera
Generic Name Lutetium Lu 177 dotatate
Strength 370 MBq/mL
Indication Lutathera® (lutetium (177Lu) oxodotreotide) was approved by Health Canada in January  2019, for the treatment of unresectable (not removable by surgery) or metastatic, well-differentiated, somatostatin receptor-positive (expressing the somatostatin receptor) gastroenteropancreatic neuroendocrine tumors (GEP-NETs) in adults with progressive disease.
Tumour Type Gastrointestinal
Contraindications
  • Severe renal impairment (creatinine clearance < 30 mL/min)
  • Established or suspected pregnancy (when pregnancy has not been excluded)
  • Hypersensitivity to the active substance or to any of the excipients listed

The pCODR Expert Review Committee  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

The INESSS  recommendation was issued February 2019Funded as a Médicament d’exception for neuroendocrine tumours in the digestif tract or pancreatic well differentiated, advanced disease, non resectable or metastatic expressing the somatostatin receptor in adults. ( see conditions )

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.
