The European Commission has granted orphan drug designation to ERapa, a promising investigational therapy developed by Reata Pharmaceuticals, for the treatment of Alport syndrome, a rare inherited disorder affecting the kidneys, ears and eyes.
Alport syndrome is caused by mutations in the genes responsible for encoding type IV collagen, a key structural component of basement membranes. These mutations result in progressive kidney dysfunction, hearing loss and ocular abnormalities. The condition is estimated to affect approximately 1 in 50,000 individuals worldwide, with a high likelihood of progression to end-stage renal disease.
ERapa is an oral, once-daily activator of the Nrf2 pathway, a cellular defense mechanism. It is designed to reduce oxidative stress, restore mitochondrial function and modulate inflammation, mechanisms thought to be critical in slowing the progression of kidney damage in Alport syndrome. In clinical trials, including the Phase 2 portion of the CARDINAL study, ERapa demonstrated encouraging results in improving kidney function, as measured by increased estimated glomerular filtration rate (eGFR).
The orphan drug designation provides several regulatory incentives to support the continued development of ERapa. These include market exclusivity for up to 10 years following approval, fee reductions and access to scientific guidance from the European Medicines Agency (EMA). Such measures are intended to foster innovation for conditions with limited or no effective treatment options.
This designation marks a meaningful step forward in the effort to bring new therapies to patients with rare and often overlooked diseases like Alport syndrome.
