Abstract

Objectives: Antiretroviral therapy (ART) accounts for a considerable proportion of HIV care expenses. In June 2021, a Dutch healthcare insurer implemented a mandatory policy to de-simplify branded RPV/TDF/FTC (Eviplera) into a two-tablet regimen containing rilpivirine (Edurant) and generic TDF/FTC as part of cost-saving measures. The objectives of this study were to evaluate the acceptance of this policy, the trends in ART dispensation, and cost developments.

Design: A retrospective database study.

Methods: In this study, medication dispensation data were obtained from the Dutch Foundation for Pharmaceutical Statistics (SFK). This database covers 98% of all medication dispensations from Dutch pharmacies including people with HIV who receive ART. We received pseudonymized data exclusively from individuals insured by the insurer for the years 2020-2022. Costs were calculated using Dutch drug prices for each year.

Results: In June 2021, 128 people with HIV were on branded RPV/TDF/FTC. Following the policy implementation, 59 (46%) had switched to RPV + generic TDF/FTC, but after 1.5 years, only 17 of 128 individuals (13%) used the proposed two-tablet regimen. The other 111/128 used RPV/TDF/FTC with prescriptions for 'medical necessity' ( n = 29), switched to RPV/TAF/FTC ( n = 51), or other ART ( n = 31). Despite expectations of cost-savings, costs increased from €72 988 in May 2021 to €75 649 in May 2022.

Conclusion: A mandatory switch from an STR to a TTR in people with HIV proved unsuccessful, marked by low acceptance, and increased costs after 1 year. This underscores the necessity of incorporating patient and prescriber involvement in changing medication policies.
