Delivery of AAV‐based gene therapy through haemophilia centres—A need for re‐evaluation of infrastructure and comprehensive care: A Joint publication of EAHAD and EHC

Introduction

Adeno-associated virus (AAV)-based gene therapy for haemophilia presents a challenge to the existing structure of haemophilia centres and requires a rethink of current collaboration and information exchange with the aim of ensuring a system that is fit-for-purpose for advanced therapies to maximise benefits and minimise risks. In Europe, a certification process based on the number of patients and facilities is offered to the haemophilia centres by European Haemophilia Network (EUHANET).

Aim and methods

This joint European Association for Haemophilia and Allied Disorders (EAHAD) and European Haemophilia Consortium (EHC) publication describes criteria for centres participating in gene therapy care that require a reassessment of the infrastructure of comprehensive care and provides an outlook on how these criteria can be implemented in the future work of haemophilia centres.

Results

The core definition of a haemophilia treatment centre remains, but additional roles could be implemented. A modifiable ‘hub-and-spoke’ model addresses all aspects associated with gene therapy, including preparation and administration of the gene therapy product, determination of coagulation and immunological parameters, joint score and function, and liver health. This will also include the strategy on how to follow-up patients for a long-term safety and efficacy surveillance.

Conclusion

We propose a modifiable, networked ‘hub and spoke’ model with a long term safety and efficacy surveillance system. This approach will be progressively developed with the goal of making haemophilia centres better qualified to deliver gene therapy and to make gene therapy accessible to all persons with haemophilia, irrespective of their country or centre of origin.
