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:
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 |
- progression-free survival (PFS) [ Time Frame: 12 weeks +/- 14 days, up to 30 months ]PFS will be assessed individually per patient from date of randomization until the date of first documented progression, assessed up to 30 months, primary outcome will be measured by CT/MRI every 12 weeks +/- 14 days
- overall survival (OS) [ Time Frame: every 3 months for a period of at least 30 months ]OS as secondary outcome measure will be assessed per patient from date of randomization until the date of death, whichever came first
