BridgeBio Pharma and Affiliate Origin Biosciences Announce FDA Approval of NULIBRY (fosdenopterin), the First and Only Approved Therapy to Reduce the Risk of Mortality in Patients with MoCD Type A - Seite 2

Animal studies have identified that NULIBRY has phototoxic potential. In the clinical trials, the most common adverse reactions reported in two or more Nulibry-treated patients with MoCD Type A were catheter-related complications (89%), pyrexia (fever; 78%), viral infection (56%), pneumonia (44%), otitis media (ear infection; 44%), vomiting (44%) and cough/sneezing (44%). Adverse reactions for the rcPMP-treated patients were similar to the NULIBRY-treated patients.

“Today’s approval represents new hope for patients and families affected with MoCD Type A,” said Donald Basel, M.D., section chief and associate professor of pediatrics at Children’s Wisconsin. “I am encouraged by the clinical data showing that NULIBRY not only lowers the levels of toxic SSC, but importantly extends the lives of patients who previously had only a three- to four-year median survival.”

NULIBRY was reviewed under Priority Review and received Orphan Drug Designation, Breakthrough Therapy Designation and Rare Pediatric Disease Designation from the FDA. With this approval, the FDA also issued a Rare Pediatric Disease Priority Review Voucher (PRV) to Origin.

BridgeBio and Origin are committed to patient access and have developed a comprehensive patient support program, ForgingBridges, to help patients access NULIBRY. ForgingBridges also provides tools and resources to help patients and caregivers throughout their treatment journey with NULIBRY.

About Molybdenum Cofactor Deficiency (MoCD) Type A
MoCD Type A is an autosomal recessive, inborn error of metabolism caused by mutations in the molybdenum cofactor synthesis 1 gene (MOCS1) and characterized by a deficiency in molybdenum cofactor (MoCo) production, leading to a lack of molybdenum-dependent enzyme activity^1,2. The lack of activity leads to decreased sulfite oxidase activity with buildup of sulfite and secondary metabolites (such as S-sulfocysteine (SSC)) in the brain, which causes irreversible neurological damage.²

MoCD Type A is an ultra-rare disease. The incidence and prevalence of MoCD Type A in the United States are not known, but the estimated incidence is 1 per 342,000 to 411,000 live births (0.24 and 0.29 per 100,000).³ Based on these estimates, MoCD Type A is likely to be underdiagnosed, with an estimated 22 to 26 missed diagnoses per year in the United States and European Union.
