Agreement about Availability of Alternative Treatments for Innovative Drugs Assessed by the EMA and HTA Organizations.

Abstract

The European Medicines Agency (EMA) and European national/regional health technology assessment (HTA) organizations consider the availability of existing treatments when evaluating a new drug. Since disagreement about the availability of alternative treatments may impact patient access to new drugs, this study aimed to investigate whether the EMA and HTA organizations agreed on the availability of alternative treatments and whether a lack of alternative treatments was associated with HTA organizations' added benefit assessment outcomes. For 97 innovative drugs authorized in 2019-2021 (excluding vaccines and diagnostic tools), assessments by the EMA and AEMPS (Spain), AIFA (Italy), HAS (France), IQWiG/G-BA (Germany), NICE (England and Wales), and ZIN (the Netherlands) were identified. Until 1 June 2022, 429 HTA drug-indication combinations were identified for these 97 drugs, of which 205 exactly matched the EMA's indication. For those, the overall agreement between the EMA and HTA organizations on whether alternative treatments were available was 87%. The agreement of HTA organizations with the EMA on whether available treatments were either pharmacological on-label, pharmacological off-label, or non-pharmacological was 87%, 21%, and 57%, respectively. For all 429 HTA drug-indication combinations, absence of alternative treatments as considered by HTA organizations was associated with a higher chance to provide added benefit: risk ratio 1.8 (95%-CI 1.4-2.3). In conclusion, although there was high overall agreement between the EMA and HTA organizations about whether alternative treatments exist, there were differences in the types of treatment considered. Parallel joint scientific consultations could inform drug developers about relevant alternative treatments to facilitate patient access to innovative drugs.
