NETTER-1 Overall survival 

In the phase III NETTER-1 trial, patients with advanced, progressive neuroendocrine tumours (NETs) were randomised to LUTATHERA® (lutetium [177Lu] oxodotreotide) (every 8 weeks, four cycles) plus octreotide long-acting release (LAR) 30 mg or octreotide LAR 60 mg (of note, the 60 mg dose is not the licensed dose).1

In the primary analysis, the study showed a significantly longer progression-free survival (PFS) in the LUTATHERA arm.2 The final analysis showed a positive trend in overall survival (OS) (not statistically significant; median OS of 48.0 months [95% confidence interval (CI): 37.4–55.2] in the LUTATHERA arm vs 36.3 months [95% CI: 25.9–51.7] with high-dose octreotide LAR; p=0.30).
