Budget impact of adding lesinurad for second-line treatment of gout: a US health plan perspective.

Aim: To estimate budget impact of adopting lesinurad as add-on to allopurinol for urate-lowering therapy in gout.

Methods

A budget impact model was developed for a US payer perspective, using a Markov model to estimate costs, survival and discontinuation in a one-million-member health plan. The population included patients failing first-line gout therapy, followed for 5 years.

Results

Incremental costs of adding lesinurad versus no lesinurad were US$241,907 and US$1,098,220 in first and fifth years, respectively. Cumulative 5-year incremental cost was US$3,633,440. Estimated incremental mean cost per treated patient with gout per year was US$112. The mean per-member per-month cost increased by US$0.06.

Conclusion

Initiating lesinurad would result in an incremental per-member per-month cost of US$0.06 over 5 years.
