FDA Accepts NDA for Menkes Disease Drug
FDA has accepted for review a Fortress Biotech NDA for CUTX-101 (copper histidinate) for treating Menkes disease, a rare X-linked recessive pediatric disease caused by gene mutations of the copper transporter ATP7A. The submission has been granted priority review and a user fee action date of 6/30.
Menkes disease, which primarily affects male infants, leads to copper accumulating at abnormally low levels in the liver and brain, but at higher-than-normal levels in the kidney and intestinal lining.
The NDA is based on clinical data showing statistically significant improvement in overall survival for Menkes disease subjects who received early treatment with CUTX-101, with a nearly 80% reduction in death risk compared to an untreated historical control cohort, the company says. “Median overall survival was 177.1 months for CUTX-101 early treatment cohort compared to 16.1 months for the untreated historical control cohort,” it says. CUTX-101 was previously granted FDA Breakthrough Therapy, Fast Track, Rare Pediatric Disease and Orphan Drug designations.
