Purpose of the Study

This study aimed to find a better way to analyze microperimetry data, which helps evaluate the effectiveness of gene therapy for inherited retinal diseases (IRDs).

Methods

We looked at data from a phase II trial of AGTC-501 in patients with X-linked retinitis pigmentosa (XLRP). We used a special device called the Macular Integrity Assessment (MAIA) to check how consistent our results were. We also applied a statistical model to see if improvements in vision were likely just by chance.

Results

Our analysis showed that the chance of seeing significant improvements in vision between two testing visits was very low (< 5%). We found that the probability of actually seeing improvements in vision due to the treatment, rather than just luck, was about 5.3%.

Conclusions

The new approach we suggested helps to balance the analysis of data while remaining statistically significant. By focusing on at least 7 locations showing improvement, we can better identify real treatment effects without being too cautious.

Translational Relevance

This new statistical method could enhance the evaluation of treatments in gene therapy trials for IRDs. It helps provide a more accurate measure of how effective these therapies are, ultimately aiding in better clinical decisions.
