Project Aim

Through surveys of Australians living with inherited retinal diseases (IRDs) our aim was to analyse the perspectives of patients regarding their understanding of and interest in both currently approved and future hypothetical gene therapy for retinal dystrophy, and a comparison between how approved and hypothetical gene therapies are viewed. This information would shed light on patient understanding, guide future gene therapy trials and treatments in Australia, and may be used by health economists to apply for government funding for gene therapy for IRD in the future.

Project Results and Impact

This study is the first comprehensive analysis of the perspectives of Australian people with IRD regarding understanding of and interest in gene therapy for retinal disease. Most of the survey respondents (92%) said that they would try gene therapy if it was available now to them or their family members for IRD. However, only 28.3% agreed that they had good knowledge of gene therapy and almost 60% of respondents did report at least one barrier to their future uptake of the treatment. Most obtained information about gene therapy from the internet (49.3%). Knowledge gaps were present regarding methods and outcomes of gene therapy. Most respondents saw economic value in treatment, with 79% agreeing that government subsidy would be an effective use of taxpayer money. This survey has shown high level of interest in the IRD community for gene therapies and highlights the importance of continued research and development into new therapies for people with IRDs.
