RE: Why These Results are huge23 Apr 2019 19:27
So, LUXTURNA treats one of the potentially numerous gene mutations (RPE65) that can cause RP. Whereas the Reneuron product hRPC is non-gene specific (as far as my understanding goes) so can treat a much much larger area of the potential market.
Visual acuity s the most common measure of visual function both in clinical practice as well as in clinical trials. However, in the Phase III study for LUXTURNA, they basically found out VA wasn't giving them the results they were after, and the reviewer commented on the paper that the "applicant decided not to use change in VA as the primary endpoint for the Phase 3 trial."
The VA results for our hRPC trials so far have shown an increase of between 14 to 20 letters for the first cohort of subjects. As far as I understand, the 0.3 LogMAR would equate to 15 letters improvement (someone please correct me if this understanding is wrong).
Resutls from next cohort will be very interesting indeed, as if this level of improvement can be sustained across a larger group, then it's difficult to see how hRPC does not have a great level of potential than LUXTURNA - clearly with the caveat that there is still considerable further testing to be done before it is ready for market!
