Abstract

Abstract: Background and aims: In France, there are approximately 2, 400 new cases of neuroendocrine tumors (NETs) annually. Peptide receptor radionuclide therapy with 177 Lu-Dotatate plus long-acting repeatable [LAR] octreotide 30 mg has been shown to significantly improve progression-free survival and overall survival relative to high-dose octreotide LAR 60 mg in patients with unresectable or metastatic progressive midgut NETs. A long-term cost-effectiveness analysis was performed to assess whether 177 Lu-Dotatate is a cost-effective option versus octreotide 60 mg for patients with unresectable/metastatic progressive midgut NETs from the perspective of French healthcare payer. Methods: The analysis was performed using a three-state partitioned survival model. In the base case analysis 177 Lu-Dotatate plus octreotide LAR 30 mg was compared with high-dose octreotide LAR 60 mg in patients with midgut NETs. Survival data were obtained from the phase III NETTER-1 trial in patients with metastatic midgut NETs. Future costs and clinical outcomes were discounted at 4% per annum . One-way deterministic and probabilistic sensitivity analyses were performed. Results: In the base case analysis, for patients with midgut NETs, 177 Lu-Dotatate treatment improved quality-adjusted life expectancy by 1.21 quality-adjusted life years (QALYs) relative to octreotide LAR 60 mg and the lifetime treatment costs were EUR 50, 784 higher with 177 Lu-Dotatate resulting in an incremental cost-effectiveness ratio (ICER) of EUR 42, 106 per QALY gained versus octreotide LAR 60 mg. When compared with everolimus, 177 Lu-Dotatate was associated with an ICER of EUR 59, 769 per QALY gained. Sensitivity analyses showed that the results were sensitive to methods used to extrapolate survival data. Conclusions: For patients with advanced progressive midgut NETs 177 Lu-Dotatate is likely to be considered a cost-effective option versus octreotide 60 mg from the perspective of the French healthcare payer.
