Abstract
Background
Gemcitabine (GEM), oxaliplatin plus GEM (OX + GEM), cisplatin plus GEM (CIS + GEM), capecitabine plus GEM (CAP + GEM), FOLFIRINOX (FFX), and nab-paclitaxel plus GEM (NAB-P + GEM) are the most commonly used regimens as first-line treatment of metastatic pancreatic cancer (MPC) in the UK. Independent economic evaluation of these regimens simultaneously has not been conducted for the UK.
Objective
Using data from a network meta-analysis as efficacy measures, we estimated the cost effectiveness and cost utility of these regimens for the UK.
Methods
A three-state Markov model (progression-free, progressed-disease, and death) simulating the total costs and health outcomes (quality-adjusted life-years [QALYs] gained and life-years [LYs]) was developed to estimate the incremental cost-utility (ICUR) and incremental cost-effectiveness ratios (ICER) for patients with MPC, from the payer perspective. The model was specified to calculate total costs in 2017 British pounds (GBP, £). All values were discounted at 3.5% per year over a full lifetime horizon. One-way sensitivity and probabilistic sensitivity analyses were conducted to assess the impact of parameter uncertainty on the results.
Results
FFX was the most effective regimen, NAB-P + GEM was the most costly regimen, and GEM was the least costly and least effective regimen. OX + GEM, CIS + GEM, and NAB-P + GEM were dominated by CAP + GEM and FFX. Compared with GEM, the ICUR for CAP + GEM and FFX was £28,066 and £33,020/QALY gained, respectively; compared with GEM, the ICER for CAP + GEM and FFX was £17,437 and £22,291/LY gained, respectively; and compared with CAP + GEM, the ICUR and ICER for FFX were £34,947/QALY gained and 24,414/LY gained, respectively.
Conclusions
At a threshold value of £30,000/QALY, CAP + GEM was found to be the only cost-effective regimen in the management of MPC in the UK.
