Healthcare costs were collected prospectively through electronic trial records. Quality-adjusted life years (QALYs) were estimated using mapping algorithms for EuroQoL-5 Dimension. Multiple imputation was used to handle missing data and bootstrapping to calculate CIs. Robustness was tested with biological disease-modifying antirheumatic drugs at biosimilar prices.Results In the high-risk group, Classic (∆k€1.464, 95% CI −0.198 to 3.127) and Avant-Garde (∆k€0.636, 95% CI −0.987 to 2.258) were more expensive compared with Slim and QALYs were slightly worse for Classic (∆−0.002, 95% CI −0.086 to 0.082) and Avant-Garde (∆−0.009, 95% CI −0.102 to 0.084). This resulted in the domination of Classic and Avant-Garde by Slim. In the low-risk group, Slim was cheaper (∆k€−0.617, 95% CI −2.799 to 1.566) and QALYs were higher (∆0.141, 95% CI 0.008 to 0.274) compared with TSU, indicating Slim dominated. Results were robust against the price of biosimilars.Conclusions The combination of MTX with a GC bridging scheme is less expensive with comparable health utility than more intensive step-down combination strategies or a conventional step-up approach 2 years after initial treatment.Trial registration number NCT01172639.
