Abstract

Background: Treatments for metastatic pancreatic cancer include monotherapy with gemcitabine (GEM); combinations of GEM with oxaliplatin (OX + GEM), cisplatin (CIS + GEM), capecitabine (CAP + GEM), or nab-paclitaxel (NAB-P + GEM); and the non-GEM combination FOLFIRINOX. Combination therapies have yielded better survival outcomes than GEM alone. A sponsor-independent economic evaluation of these regimens has not been conducted for USA. Objective: The objective of this study was to estimate the cost utility and cost effectiveness of these regimens from the payer perspective for USA. Methods: A three-state Markov model (progression-free, progressed disease, death) simulating the total costs and health outcomes (quality-adjusted life-years; life-years) was developed to estimate the incremental cost-utility and cost-effectiveness ratios. FOLFIRINOX clinical data were obtained from trial and indirect estimates were obtained from network meta-analyses. Lifetime horizon and 3%/year discount rates were used. Results: FOLFIRINOX was the most expensive regimen and GEM the least costly regimen. Compared to GEM, all but one (CIS + GEM) regimen were found to be more effective in quality-adjusted life-years and life-years. Compared to GEM, the incremental cost-utility ratios for CAP + GEM, OX-GEM, NAB-P + GEM, and FOLFIRINOX, were US$180,503, US$197,993, US$204,833, and US$265,718 per additional quality-adjusted life-year, respectively; and the incremental cost-effectiveness ratios were US$88,181, US$87,620, US$135,683, and US$167,040 per additional life-year, respectively. A probabilistic sensitivity analysis confirmed the base-case analysis. Conclusions: This sponsor-independent economic evaluation for USA found that OX + GEM, CAP + GEM, FOLFIRINOX, and NAB-P + GEM, but not CIS + GEM, were more expensive but also more effective than GEM alone in terms of quality-adjusted life-years and life-years gained. The NAB-P + GEM regimen appears to be the most cost effective in USA at a willingness-to-pay threshold of US$200,000/quality-adjusted life-year.
