BridgeBio Pharma And Affiliate Origin Biosciences Announces FDA Acceptance Of Its New Drug Application For Fosdenopterin For The Treatment Of MoCD Type A
SAN FRANCISCO, September 29, 2020 – BridgeBio Pharma, Inc. (Nasdaq: BBIO) and affiliate Origin Biosciences today announced the US Food and Drug Administration (FDA) has accepted its New Drug Application (NDA) for fosdenopterin (previously BBP-870/ORGN001), a cyclic pyranopterin monophosphate (cPMP) substrate replacement therapy, for the treatment of patients with molybdenum cofactor deficiency (MoCD) Type A.
The NDA has been granted Priority Review designation. Fosdenopterin has previously been granted Breakthrough Therapy Designation and Rare Pediatric Disease Designation in the US and may be eligible for a priority review voucher if approved. It received Orphan Drug Designation in the US and Europe. This is BridgeBio’s first NDA acceptance.
“We want to thank the patients, families, scientists, physicians and all others involved who helped us reach this critical milestone,” said BridgeBio CEO and founder Neil Kumar, Ph.D. “MoCD Type A is a devastating disease with a median survival of less than four years and we are eager for our investigational therapy to be available to patients, who currently have no approved treatment options. BridgeBio exists to help as many patients as possible afflicted with genetic diseases, no matter how rare. We are grateful that the FDA has accepted our first NDA for priority review and we look forward to submitting our second NDA later this year for infigratinib for second line treatment of cholangiocarcinoma.”
Fosdenopterin is being developed for the treatment of patients with MoCD Type A. Currently, there are no approved therapies for the treatment of MoCD Type A, which results in severe and irreversible neurological injury with a median survival between 3 to 4 years. Fosdenopterin is a first-in-class cPMP hydrobromide dihydrate and is designed to treat MoCD Type A by replacing cPMP and permitting the two remaining MoCo synthesis steps to proceed, with activation of MoCo-dependent enzymes and elimination of sulfites.
About Molybdenum Cofactor Deficiency (MoCD) Type A
MoCD Type A is an ultra-rare, autosomal recessive, inborn error of metabolism caused by disruption in molybdenum cofactor (MoCo) synthesis which is vital to prevent buildup of s-sulfocysteine, a neurotoxic metabolite of sulfite. Patients are often infants with severe encephalopathy and intractable seizures. Disease progression is rapid with a high infant mortality rate.Those who survive beyond the first few month’s experience profuse developmental delays and suffer the effects of irreversible neurological damage, including brain atrophy with white matter necrosis, dysmorphic facial features, and spastic paraplegia. Clinical presentation that can be similar to hypoxic-ischemic encephalopathy (HIE) or other neonatal seizure disorders may lead to misdiagnosis and underdiagnosis. Immediate testing for elevated sulfite levels and S-sulfocysteine in the urine and very low serum uric acid may help with suspicion of MoCD.
