Abstract
Objective: To evaluate the cost-effectiveness of trastuzumab emtansine (T-DM1) compared to both lapatinib plus capecitabine (lapcap) and trastuzumab plus capecitabine (trascap) for treating human epidermal growth factor 2-positive advanced breast cancer patients, who have received prior treatment with trastuzumab and a taxane, in Singapore.
Research design and methods: A three-state partitioned survival model was used to evaluate the cost-effectiveness from the local healthcare system perspective. Key effectiveness data, including progression-free survival and overall survival from the pivotal EMILIA trial, were used alongside local clinician inputs. Health state utilities (in quality-adjusted life years [QALYs]) were obtained from the literature and direct medical costs obtained from the public health institutions in Singapore. Scenario, one-way, and probabilistic sensitivity analyses were conducted to explore the impact of uncertainties on cost-effectiveness.
Results: The base-case incremental cost-effectiveness ratios (ICERs) for T-DM1, compared to lapcap and trascap, were S$472,600 and S$495,200 per QALY gained, respectively. Sensitivity and scenario analyses showed high ICERs, with a 50% price reduction for T-DM1 resulting in an ICER above S$200,000.
Conclusion: At current prices, T-DM1 is unlikely to be a cost-effective use of Singapore's limited healthcare budget. These findings can help inform policymakers, alongside other considerations, on funding decisions.
期刊介绍:
Expert Review of Pharmacoeconomics & Outcomes Research (ISSN 1473-7167) provides expert reviews on cost-benefit and pharmacoeconomic issues relating to the clinical use of drugs and therapeutic approaches. Coverage includes pharmacoeconomics and quality-of-life research, therapeutic outcomes, evidence-based medicine and cost-benefit research. All articles are subject to rigorous peer-review.
The journal adopts the unique Expert Review article format, offering a complete overview of current thinking in a key technology area, research or clinical practice, augmented by the following sections:
Expert Opinion – a personal view of the data presented in the article, a discussion on the developments that are likely to be important in the future, and the avenues of research likely to become exciting as further studies yield more detailed results
Article Highlights – an executive summary of the author’s most critical points.
