The Cost-Effectiveness of Lorlatinib Versus Chemotherapy as a Second- or Third-Line Treatment in Anaplastic Lymphoma Kinase (ALK)-Positive Non-small-cell Lung Cancer in Sweden.


ABSTRACT:

Background

Lorlatinib is a third-generation anaplastic lymphoma kinase (ALK)/c-ros oncogene 1 (ROS1) tyrosine kinase inhibitor (TKI) with efficacy in patients with ALK-rearranged non-small-cell lung cancer (NSCLC) previously treated with a second-generation ALK inhibitor or with first- and second-generation ALK inhibitors. We examined the cost-effectiveness of second- or third-line+ (2L+ or 3L+) lorlatinib in Sweden, versus chemotherapy.

Methods

A partitioned survival model with three health states (progression free, progressed, or death) was used. Lorlatinib relative efficacy versus chemotherapy was derived using unanchored matching adjusted indirect treatment comparisons from a phase 2 clinical trial. Utility data were derived from the same trial and published studies. Costs (year 2019) were obtained from Swedish national data. Costs and benefits were discounted at 3% per annum using a societal perspective (base case). Model robustness was evaluated with deterministic and probabilistic sensitivity analyses.

Results

For 2L+, the average discounted total quality-adjusted life year (QALY) gain was 1.29 years. Total incremental costs were Swedish krona (SEK) 731,791, resulting in an incremental cost-effectiveness ratio (ICER) of SEK 566,278 per QALY gained. Non-discounted survival gain amounted to 1.94 years. For 3L+, the average discounted total QALY gain was 1.25 years. Total incremental costs were SEK 754,801, resulting in an ICER of SEK 603,934 per QALY gained. Non-discounted survival gain was 1.88 years. Sensitivity analyses were consistent.

Conclusions

ICERs ranged from SEK 421,000 to SEK 384,066 less than the boundary for a cost-effective treatment for a high-severity disease in Sweden (SEK 988,000), suggesting 2L+ or 3L+ lorlatinib is a cost-effective treatment for ALK-positive NSCLC versus chemotherapy.
