Objective:
The GOG 281/LOGS trial found that trametinib prolonged progression-free survival (PFS) in patients with recurrent low-grade serous ovarian cancer (LGSOC), compared with standard of care (SOC). The current study aimed to evaluate the cost-effectiveness of trametinib versus standard of care for recurrent LGSOC from the US payer perspective.
Methods:
A Markov model was adopted to compare the cost and effectiveness of trametinib and standard of care group in patients with recurrent LGSOC. Life years (LYs), quality-adjusted LYs (QALYs), lifetime costs, and incremental cost-effectiveness ratios (ICERs) were calculated. One-way, and probabilistic sensitivity analyses were performed to explore the model robustness.
Result:
Trametinib group provided an additional 0.58 QALYs (1.14 LYs) and an incremental cost of $248,214 compared with the SOC group. The incremental cost-effectiveness ratio was $424,097 per QALY. The results of one-way sensitivity analyses suggested that our model was sensitive to the hazard ratio of OS and PFS between trametinib and SOC group, utility of PFS and the cycle cost of trametinib. Probabilistic sensitivity analyses revealed that there was 6% probability of the trametinib group being cost-effective at a willingness-to-pay (WTP) threshold of $150,000 per QALY.
Conclusions:
From the US payer perspective, trametinib is not cost-effective for patients with recurrent LGSOC at the assumed WTP threshold of $150,000 per QALY. Based on the value standpoint, price reduction of trametinib is expected to improve the cost-effectiveness of trametinib in patients with recurrent LGSOC.
