Brief Summary:
The purpose of the study is to evaluate efficacy and safety of Peptide Receptor Radionuclide Therapy (PRRT) with 177Lu-Edotreotide compared to targeted molecular therapy with Everolimus in patients with inoperable, progressive, somatostatin receptor-positive (SSTR+), neuroendocrine tumours of gastroenteric or pancreatic origin (GEP-NET).

Official Title: A Prospective, Randomised, Controlled, Open-label, Multicentre Phase III Study to Evaluate Efficacy and Safety of Peptide Receptor Radionuclide Therapy (PRRT) With 177Lu-Edotreotide Compared to Targeted Molecular Therapy With Everolimus in Patients With Inoperable, Progressive, Somatostatin Receptor-positive (SSTR+), Neuroendocrine Tumours of Gastroenteric or Pancreatic Origin (GEP-NET)
Actual Study Start Date : February 2, 2017
Estimated Primary Completion Date : December 2023
Estimated Study Completion Date : May 2024

Arm Intervention/treatment
Experimental: 177Lu-edotreotide PRRT

177Lu-edotreotide (177Lu-DOTATOC)

A maximum of four cycles of 7.5 ± 0.7 GBq (gigabequerel) 177Lu-edotreotide, each.

Route of administration: Slow intravenous infusion/injection (i.v.) Duration of treatment: 4 cycles, 90 days apart (total duration: 270 days/9 months)

Drug: 177Lu-edotreotide PRRT
PRRT using 177Lu-edotreotide will be performed 3-monthly. A maximum of four cycles will be administered.
Other Names:
  • 177Lu-DOTATOC
  • 177Lu-Edo

Other: Amino-Acid Solution
The Amino-Acid Solution (AAS) to be used in this study will contain a mixture of 25 g lysine and 25 g arginine diluted in 2000 mL of electrolyte solution, infused over 4 - 6 h, starting 30 - 60 min before PRRT
Other Name: Arginine-Lysine Solution

Active Comparator: Everolimus

Everolimus (Afinitor ®)

Doses: 10 mg/d Route of administration: Oral Duration of treatment: Continuous daily treatment until diagnosis of progression or End of Study (EOS)

Drug: Everolimus
Everolimus will be adminstered as a standard dosis of 10 mg daily which may be reduced where required for acceptable tolerability.
Other Name: Afinitor

Primary Outcome Measures :
  1. progression-free survival (PFS) [ Time Frame: 12 weeks +/- 14 days, up to 24 months ]
    PFS will be assessed individually per patient from date of randomization until the date of first documented progression, assessed up to 24 months, primary outcome will be measured by CT/MRI every 12 weeks +/- 14 days

Secondary Outcome Measures :
  1. overall survival (OS) [ Time Frame: every 3 months for a period of at least 24 months ]
    OS as secondary outcome measure will be assessed per patient from date of randomization until the date of death, whichever came first
