The impact of amortization of gene therapies funding on the results and conclusions of CEMs and BIMs.

Background: Gene replacement therapy (GRT) is a treatment method used to combat or prevent various diseases. Its high one-off cost constitutes a major obstacle for successful market access. This paper aims to assess and discuss the applicability of amortization in models, such as cost-effectiveness models (CEMs) and budget impact models (BIMs) informing HTA recommendations and reimbursement decisions.

Gene Therapy Evidence Generation and Economic Analysis: Pragmatic Considerations to Facilitate Fit-for-Purpose Health Technology Assessment.

Gene therapies (GTs) are considered to be a paradigm-shifting class of treatments with the potential to treat previously incurable diseases or those with significant unmet treatment needs. However, considerable challenges remain in their health technology assessment (HTA), mainly stemming from the inability to perform robust clinical trials to convince decision-makers to pay the high prices for the potential long-term treatment benefits provided. This article aims to review the recommendations that have been published for evidence generation and economic analysis for GTs against the feasibility of their implementation within current HTA decision analysis frameworks.

An overview of health technology assessments of gene therapies with the focus on cost-effectiveness models.

Background: Gene therapies can treat, prevent, or cure a disease by changing the expression of a person's genes. They are an innovative strategy for treating genetic disorders; however, they are still emerging on the market access and in the healthcare system. Health technology assessment (HTA) agencies have not yet elaborated any standardised approach for assessing gene therapies; therefore, significant differences can be seen during HTAs carried out in various countries.
