This article investigates whether anticipated future price declines should be considered in health technology assessments and how it can affect cost-effectiveness estimates. Through 4 case studies, it is found that generic pricing should be included for subsequent cohorts, but can be omitted for reimbursement assessments. Accounting for generic pricing can significantly reduce estimated cost-effectiveness ratios.
Objectives: Guidance on the conduct of health technology assessments rarely recommends accounting for anticipated future price declines that can follow loss of marketing exclusivity. This article explores when it is appropriate to account for generic pricing and whether it can influence cost-effectiveness estimates.Methods: This article presents 4 case studies. Case study 1 considers a hypothetical drug used by a first patient cohort at branded prices and by subsequent, downstream cohorts at generic prices. Case study 2 explores whether statin assessments should account for generic prices for downstream cohorts that gain access after the initial cohort. Case study 3 uses a simplified spreadsheet model to assess the impact of accounting for generic pricing for inclisiran, used when statins insuf-ficiently reduce cholesterol. Case study 4 amends this model for a hypothetical, advanced, follow-on treatment displacing inclisiran.Results: Assessments should include generic pricing even if the first cohort using a drug pays branded prices and only downstream cohorts pay generic prices (case study 1). Because eventual generic pricing for statins did not depend on de-cisions for downstream cohorts, assessing reimbursement for those cohorts could safely omit generic pricing (case study 2). For inclisiran (case study 3), including generic pricing notably improved estimated cost-effectiveness. Displacing inclisiran with an advanced therapy (case study 4) modestly affected estimated cost-effectiveness.Conclusions: Although this analysis relies on simplified and hypothetical models, it demonstrates that accounting for generic pricing might substantially reduce estimated cost-effectiveness ratios. Doing so when warranted is crucial to improving health technology assessment validity.
