PALO ALTO, Calif. and SOLANA BEACH, Calif., July 25, 2022 /PRNewswire/ -- BridgeBio Pharma, Inc. (Nasdaq: BBIO) (BridgeBio), a commercial-stage biopharmaceutical company that focuses on genetic diseases and cancers, and Sentynl Therapeutics, Inc. (Sentynl), a U.S.-based biopharmaceutical company focused on bringing innovative therapies to patients living with rare diseases owned by Zydus Lifesciences Ltd. (formerly known as Cadila Healthcare Ltd.), today announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has recommended that the European Commission authorize marketing under exceptional circumstances for NULIBRY® (fosdenopterin) for Injection as the first therapy for the treatment of patients with molybdenum cofactor deficiency (MoCD) Type A. MoCD Type A is an ultra-rare and progressive condition, known to impact less than 150 patients globally with a median survival of four years.

Understanding MoCD Type A

BridgeBio Pharma and Sentynl Therapeutics Receive Positive CHMP Opinion for NULIBRY® (fosdenopterin)

NULIBRY is a first-in-class cPMP substrate replacement therapy that was approved by the U.S. Food and Drug Administration (FDA) in 2021 to reduce the risk of mortality in patients with MoCD Type A. If approved by the European Commission, NULIBRY would be the first and only approved therapy in the EU for MoCD Type A.

In March 2022, Sentynl acquired the global rights to NULIBRY and is responsible for the ongoing development and commercialization of NULIBRY in the United States and developing, manufacturing, and commercializing fosdenopterin globally. Sentynl and BridgeBio share development responsibilities through the approval of the marketing authorization application under accelerated assessment with the EMA and through approval of NULIBRY's regulatory submission with the Israeli Ministry of Health.

"Our work on NULIBRY and MoCD Type A epitomizes BridgeBio's belief that no disease is too rare to address. With this positive CHMP opinion, we are closer to delivering a treatment option to all children across the globe who suffer with MoCD Type A," said BridgeBio founder and CEO Neil Kumar, Ph.D.

The positive CHMP opinion is supported by data from three clinical trials that demonstrated efficacy of NULIBRY for the treatment of patients with MoCD Type A compared to data from a natural history study. These studies showed that NULIBRY reduced the risk of death by 86% and increased the probability of survival to 86% at three years compared to 52% in the untreated, genotype-matched, historical control group in the natural history study.

"We are thrilled by the CHMP's recommendation in favor of NULIBRY and hope that patients living with MoCD Type A in Europe and around the world can access this therapy," said Matt Heck, CEO of Sentynl. "The CHMP positive opinion marks important progress not only for the program but also for the MoCD Type A patients outside of the U.S. who are seeking ways to treat their life-threatening and progressive disease."

Based on the CHMP recommendation, a decision by the EC, which authorizes marketing applications in the EU, is expected on the NULIBRY application later this year. The recommendation for marketing authorization under exceptional circumstances is granted to medicines where the applicant is unable to provide comprehensive data under normal conditions of use because the disease being treated is so rare.

In April 2022, BridgeBio received New Drug Application (NDA) Approval in Principle from the Israeli Ministry of Health and the application is currently undergoing the final review processes.

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 and characterized by a deficiency in molybdenum cofactor 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) 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 European Union are not known, but the estimated prevalence is 0.005 per 10,000 persons. Based on these estimates, MoCD Type A is likely to be underdiagnosed.

The most common presenting symptoms of MoCD Type A are seizures, feeding difficulties and encephalopathy. Patients with MoCD Type A who survive beyond infancy typically suffer from progressive brain damage, which presents in characteristic patterns on magnetic resonance imaging (MRI). This damage leads to severe psychomotor impairment and an inability to make coordinated movements or communicate with their environment.

About NULIBRY® (Fosdenopterin) for Injection

NULIBRY®(Fosdenopterin) for Injection is a substrate replacement therapy that provides an exogenous source of cPMP, which is converted to molybdopterin. Molybdopterin is then converted to molybdenum cofactor, which is needed for the activation of molybdenum-dependent enzymes, including sulfite oxidase, an enzyme that reduces levels of neurotoxic sulfites. It is the first and only FDA-approved therapy indicated to reduce the risk of mortality in patients with MoCD Type A, and clinical trials have demonstrated that patients treated with NULIBRY or rcPMP had an improvement in overall survival compared to the untreated, genotype-matched, historical control group.
