The trial participants will be followed closely for the next year, with regular testing of their vision; some will receive the treatment via injection into the eye, with others given a placebo (dummy, or sham, injection) for comparison. ProQR hopes to be able to deliver headline results from the trial in the first half of 2022; if the data demonstrates that the treatment is safe and effective, ProQR will press ahead with applications to license the treatment.

ProQR is pioneering the use of an innovative technology that uses a special molecular “patch” to cover up faults in the genetic code. Alongside the treatment for LCA10, they are also using this approach in the development of therapies for Usher syndrome, and autosomal dominant retinitis pigmentosa caused by mutations in the RHO gene; these are both at an earlier stage of testing.
This treatment approach is highly specific to certain genetic errors, meaning that potential recipients will need a genetic test result to confirm whether or not the therapy might be suitable for them.
