Advanced Therapy Medicinal Products: Availability, Access and Expenditure in Italy.

Background: Advanced therapy medicinal products (ATMPs) are an innovative output of biomedical research, characterized by a high level of uncertainty on long-term efficacy and safety, elevated price tags and often complex administration. All these elements compounded make their European authorization, national price negotiation for reimbursement and subsequent dispensation and administration to the patient less straightforward and often less successful than for less innovative drugs. To assess if these hurdles have affected patient access and how are ATMPs used in Italy, we have analysed availability, access and expenditure of ATMPs in the period spanning from 2016 to 2023.

Methods: We have analysed real world data on the duration of ATMP regulatory evaluations for authorisation and reimbursement, time to first patient access and expenditure for ATMPs through the Italian National Health System (INHS) expenditure data flow, as well as information on patient mobility and availability of health facilities specialized in administering ATMPs.

Findings: Of the 18 ATMPs currently authorized in Europe, 9 are reimbursed by the INHS, but only 6 were actually used, generating a cumulative expenditure of roughly 300 Mln€ from 2016 to 2023, largely owing to CAR-T therapies. Time to patient access reaches an average of 340.6 days from the day publication in the official Gazette of the reimbursement decision to first patient treatment in one of the 107 health facilities authorized for ATMP administration, after an even longer evaluation time by regulatory agencies.

Conclusion: Since the first reimbursement decision for an ATMP in Italy, back in 2016, these innovative drugs became progressively more and more available, both in terms of numbers and in terms of coverage across the country. Almost all Italian regions have at least one centre for ATMP administration and has performed a treatment in 2023. Notwithstanding their high per-treatment prices, ATMPs currently have a rather contained expenditure, however it is bound to keep growing in the next few years.
