Cost-effectiveness analysis of first-line treatment with crizotinib in ROS1-rearranged advanced non-small cell lung cancer (NSCLC) in Canada

Abstract Introduction While no direct comparative data exist for crizotinib in ROS1+ non-small cell lung cancer (NSCLC), studies have suggested clinical benefit with this targeted agent. The objective of this study was to assess the cost-effectiveness of crizotinib compared to standard platinum-doublet chemotherapy for first-line treatment of ROS1+ advanced NSCLC. Methods A Markov model was developed with a 10-year time horizon from the perspective of the Canadian publicly-funded health care system. Health states included progression-free survival (PFS), up to two further lines of therapy post-progression, palliation and death. Given a lack of comparative data and small study samples, crizotinib or chemotherapy studies with advanced ROS1+ NSCLC patients were identified and time-to-event data from digitized Kaplan-Meier curves were collected to pool PFS data. Costs of drugs, treatment administration, monitoring, adverse events and palliative care were included in 2018 Canadian dollars, with 1.5% discounting. An incremental cost-effectiveness ratio (ICER) was estimated probabilistically using 5000 simulations. Results In the base-case probabilistic analysis, crizotinib produced additional 0.885 life-years and 0.772 quality-adjusted life-years (QALYs) at an incremental cost of $238,077, producing an ICER of $273,286/QALY gained. No simulations were found to be cost-effective at a willingness-to-pay threshold of $100,000/QALY gained. A scenario analysis assuming efficacy equivalent to the ALK+ NSCLC population showed a slightly more favorable cost-effectiveness profile for crizotinib. Conclusions Available data appear to support superior activity of crizotinib compared to chemotherapy in ROS1+ advanced NSCLC. At the list price, crizotinib was not cost-effective at commonly accepted willingness-to-pay thresholds across a wide range of sensitivity analyses.

e19001 Background: A recent phase III clinical trial, EURTAC, demonstrated that first-line treatment with erlotinib significantly improved progression-free survival (PFS) compared with standard chemotherapy in advanced non-small cell lung cancer (NSCLC) patients whose tumors harbored epidermal growth factor receptor (EGFR) mutations (Rosell 2012). We sought to estimate the cost-utility of treatment with erlotinib in this patient population from the US payer perspective. Methods: We developed a Markov model with three health states: PFS, progression, and death. Patients received treatment until progression, unacceptable toxicity or death; patients randomized to chemotherapy received a maximum of 4 treatment cycles. Transition probabilities were extrapolated from the trial. Median PFS was 9.7 months in patients receiving erlotinib and 5.2 months in patients receiving chemotherapy (p<0.0001). Cost and utility data were obtained from the literature. Probabilistic sensitivity analysis (PSA) was performed to assess uncertainty. We evaluated two scenarios: 1) first-line erlotinib vs. first-line chemotherapy, and 2) first-line erlotinib and mixed second-line treatments vs. first-line chemotherapy and second-line erlotinib. Results: First-line treatment with erlotinib vs. chemotherapy resulted in an increase of 0.60 life-years or 0.44 quality-adjusted life-years (QALYs). Mean total costs were $59,300 in the erlotinib arm and $17,800 in the chemotherapy arm, yielding an incremental cost-effectiveness ratio (ICER) of $98,338 with a 53% probability of being cost-effective at a willingness to pay (WTP) of $100,000/QALY. In the second scenario, the ICER was $50,002/QALY, with a 66% probability of being cost-effective. The main cost drivers in the model were the time spent in the PFS health state and drug costs. Conclusions: Treatment with erlotinib in first-line EGFR-positive NSCLC results in increased costs but also substantial increases in QALYs, demonstrating that this personalized approached to treatment may be cost-effective.

Aim: This analysis aimed to evaluate the cost–effectiveness of pembrolizumab monotherapy as first-line treatment in advanced non-small-cell lung cancer patients with a programmed death ligand 1 (PD-L1) tumor proportion score ≥1% from a US payer perspective. Materials & methods: A partitioned survival model was developed using efficacy and safety data from the KEYNOTE-042 trial and projected over 20 years. Costs accounted for treatment, toxicity and disease management. Quality-adjusted life-years (QALYs) and incremental cost–effectiveness ratios were reported. Results: Pembrolizumab resulted in an expected gain of 0.60 life years and 0.49 QALYs compared with platinum-based chemotherapy. The incremental cost–effectiveness ratio was US$130,155/QALY. Conclusion: Pembrolizumab is projected to be cost-effective compared with platinum-based chemotherapy as first-line treatment for advanced non-small-cell lung cancer with PD-L1 tumor proportion score ≥1%.
