NULIBRY (fosdenopterin), First and Only FDA-Approved Therapy to Reduce the Risk of Mortality in Patients with Molybdenum Cofactor Deficiency Type A, Available Exclusively at Biologics by McKesson

April 19, 2021

CARY, N.C., April 19, 2021Biologics by McKesson, an independent specialty pharmacy specializing in oncology and rare disease areas, was selected by Origin Biosciences, Inc., an affiliate of BridgeBio Pharma, Inc. (BridgeBio), as the exclusive specialty pharmacy provider for NULIBRYTM (fosdenopterin) for Injection as the first therapy to reduce the risk of mortality in patients with Molybdenum Cofactor Deficiency (MoCD) Type A.

NULIBRY was approved by the U.S. Food and Drug Administration (FDA) on February 26, 2021. MoCD Type A is an ultra-rare, life-threatening genetic disorder that progresses rapidly and results in severe and largely irreversible neurological injury. Infants who survive the first few months typically have severe injuries to the nervous system with a median survival of four years. These infants have a deficiency in the production of an essential substance known as molybdenum cofactor (MoCo), leading to a lack of molybdenum-dependent enzyme activity.

NULIBRY for injection is a substrate replacement therapy that provides an exogenous source of cPMP, which is converted to molybdopterin. Molybdopterin is then converted to MoCo, which is needed for the activation of molybdenum-dependent enzymes, including sulfite oxidase, with restoration of associated activity including mitochondrial associated sulfite elimination.

“Before NULIBRY, the standard of care for MoCD Type A was limited to supportive therapy, including the use of anti-seizure medicines,” said Ashleigh Burdette, senior director of Clinical Innovation at Biologics. “Now, MoCD Type A patients and their families have an approved therapy for the first time. Our goal is to quickly ship NULIBRY to a hospital when MoCD Type A is suspected, because we know that for patients with this condition, every minute counts.”

“BridgeBio seeks to discover, create, test and deliver transformative medicines to treat patients who suffer from genetic diseases and cancers with clear genetic drivers,” said Matt Outten, chief commercial officer at BridgeBio. “This is our first drug approval, and we are grateful for the opportunity to help families who are struggling with this devastating disorder. We are proud to be launching this drug in tandem with our “ForgingBridges” patient assistance program, which is designed to help patients access NULIBRY and support them throughout their treatment journey. We are committed to increasing awareness and understanding of MoCD Type A and encouraging testing as soon as MoCD Type A is suspected.”
