What was measured

Overall Survival (OS) was defined as the time from the date of randomization to the date of death due to any cause or the date of last contact (censored observation) prior to the date of the data cut-off, and during the entire study period (i.e. the treatment period plus follow-up).

Analysis population: Full Analysis Set (FAS).

Groups in this outcome

177Lu-DOTA0-Tyr3-Octreotate

* 30 mg Octreotide LAR treatment for symptom control continued until the end of study, unless the participant progressed or died. * Treatment consisted of a cumulative administered radioactivity of 29.6 Giga Becquerel (GBq) (800 mCi) 177Lu-DOTA0-Tyr3-Octreotate: Four administrations of 7.4 GBq (200 mCi). * Concomitant amino acids were given with each administration for kidney protection. * 177Lu-DOTA0-Tyr3-Octreotate was administered at 8 +/- 1-week intervals, which could be extended up to 16 weeks to accommodate resolving acute toxicity. * In case participants experienced clinical symptoms (i.e. diarrhoea and flushing) associated with their carcinoid tumours, Octreotide s.c. rescue injections were allowed.

Octreotide LAR

* 60 mg Octreotide LAR treatment every 4 weeks (i.m. injections) until the end of the study, unless the participant progressed or died. * In case participants experienced clinical symptoms (i.e. diarrhoea and flushing) associated with their carcinoid tumours, s.c. Octreotide rescue injections were allowed.
