PYC-001

Autosomal Dominant Optic Atrophy (ADOA)

ADOA is a progressive and blinding eye disease

Degenerative sight of an ADOA patient

grid_image-1
10 Years old

Patient is usually diagnosed in early childhood

grid_image-2
30 YEARS OLD

Patient first loses central vision and then peripheral vision

grid_image-3
50 YEARS OLD

Patient is often diagnosed as legally blind

PATIENT

dna grouped
Group 138

DNA

ADOA patients have a mutation in one copy of the OPA1 gene

rna
RNA

RNA

The mutation leads to an unstable RNA message that is rapidly degraded

OPA1
Protein

This leads to cells in the retina having half as much OPA1 protein as they require to function normally

Functional OPA1 expression = ~50-70%

ADOA patients have a mutation in one copy of the OPA1 gene, leading to retinal cells having half as much OPA1 protein required for normal function

Restoration of OPA1 expression towards 100%

PYC-001 increases expression of the remaining healthy copy of OPA1 to compensate for the protein insufficiency
