Abstract

BACKGROUND: The 2 somatostatin analogs currently recommended by the National Comprehensive Cancer Network for the treatment of gastrointestinal (GI) neuroendocrine tumors (NETs) include octreotide long-acting release (Sandostatin LAR) for injectable suspension and lanreotide (Somatuline Depot) injection for subcutaneous use. OBJECTIVE: To estimate the costs to payers associated with 30-mg octreotide LAR and 120-mg lanreotide treatment among patients with metastatic GI-NETs. METHODS: The costs to payers associated with the 2 drugs were estimated by including the costs of each drug, drug administration, and adverse events. The unit drug costs for octreotide LAR and for lanreotide were obtained from ReadyPrice Wholesale Acquisition Cost; the doses were obtained from published studies. The adverse event rates were obtained from 2 phase 3 clinical trials, PROMID and CLARINET. Deterministic one-way sensitivity analyses were used to assess the impact of modifying assumptions and inputs on the results, including the 2017 Average Sales Price (ASP). All costs were estimated in 2016 US dollars, with a constant discount of 3%. RESULTS: The costs to payers associated with the treatment of GI-NETs during 1-, 3-, and 5-year horizons were $74,566, $180,082, and $262,344, respectively, for octreotide LAR and $84,856, $205,562, and $299,667, respectively, for lanreotide. Thus, octreotide LAR was associated with lower costs by $10,290 (1 year), $25,480 (3 years), and $37,323 (5 years) compared with lanreotide. Over a 5-year horizon, the costs of adverse events and administration accounted for 0.72% of the total cost for octreotide LAR and 0.51% of the total cost for lanreotide. Sensitivity analyses confirmed that the main factor affecting the cost difference was the price of the drugs; analyses using the ASP yielded similar results. CONCLUSION: For the management of metastatic GI-NETs, the cost to payers of treatment with 30-mg octreotide LAR is considerably lower than with 120-mg lanreotide over 1-, 3-, and 5-year horizons. In the presence of healthcare resource constraints, these findings may support decision-making when considering the care of patients with metastatic GI-NETs.
