Risk of death was 5.1 times higher in untreated patients versus patients treated with NULIBRY Treatment also led to improvements in urinary biomarker levels and development outcomes NULIBRY is the first therapy to reduce the risk of mortality in patients with known or presumed MoCD Type A SOLANA BEACH, Calif., Sept. 7, 2023 /PRNewswire/ -- Sentynl Therapeutics, Inc. (Sentynl), a U.S.-based biopharmaceutical company focused on bringing innovative therapies to patients living with rare diseases, announced that data evaluating NULIBRY® (fosdenopterin) for the treatment of patients with molybdenum cofactor deficiency (MoCD) Type A were presented at the 2023 Society for the Study of Inborn Errors of Metabolism (SSIEM) Annual Meeting on Aug. 30 in Jerusalem. NULIBRY is indicated to reduce the risk of mortality in patients with MoCD Type A, an ultra-rare, autosomal recessive, inborn error of metabolism causing sulfite-induced neurodegeneration and early death. "Clinicians must consider MoCD in infants with encephalopathy or intractable seizures," said Dr. Guenter Schwarz, Professor for Biochemistry at the Department of Chemistry & Center for Molecular Medicine, Cologne University, Germany. "Early treatment with fosdenopterin (NULIBRY) improves survival and neurodevelopmental outcomes, reducing burden on patients and caregivers." In comparison of three non-randomized retrospective and prospective open-label studies versus a retrospective and prospective natural history study, the authors reported the following survival and clinical outcomes of patients treated with recombinant cPMP/NULIBRY: Risk of death was 5.1 times higher in untreated MoCD Type A patients compared to those treated with rcPMP/NULIBRY (Cox proportional hazards [95% CI]=5.1 [1.32, 19.36], P=0.0144). Treatment with rcPMP/NULIBRY led to a normalization of MoCD Type A-associated urinary biomarker levels. Treated patients were more likely than untreated patients to feed orally and meet growth and developmental milestones. "These results were pooled from a series of carefully designed studies and corroborate previous anecdotal findings. Early treatment of children with typical neonatal disease manifestation has a dramatic effect on their survival and overall development," said Dr. Bernd C. Schwahn, Consultant in Paediatric Metabolic Medicine, Manchester Centre for Genomic Medicine, St. Mary's Hospital, in Manchester, United Kingdom. "Increased disease awareness and the use of new technologies, including improved biochemical testing and rapid whole genome sequencing, will help to shorten the diagnostic gap and allow timely access to effective treatment for a higher proportion of affected children." Based on these data, NULIBRY was approved by the U.S. Food and Drug Administration, the European Medicines Agency and the Israeli Ministry of Health. To further evaluate the safety and efficacy of NULIBRY, a post-approval non-interventional study is being initiated in Europe. "Given Sentynl's focus on meaningful treatments for serious rare diseases, we are grateful to the authors for presenting these data and increasing awareness of MoCD Type A in the medical community," said Matt Heck, CEO of Sentynl. "We thank the patients, their families and caregivers, and all investigators involved in this study. We remain focused on continued evaluation of NULIBRY to reduce the risk of mortality and progression of this devastating disease." Treatment with NULIBRY/rcPMP was generally well-tolerated in patients with MoCD Type A. Most patients experienced a treatment-emergent adverse event (TEAE), the majority of which were catheter-related or infections and were mild to moderate in severity. In the retrospective study, two serious TEAEs of death occurred, one from RSV pneumonia (unrelated to treatment), and one from necrotizing enterocolitis (possibly related to treatment).

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 estimated prevalence of MoCD Type A in the European Union is 0.005 per 10,000. 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. NULIBRY is approved by the U.S. Food and Drug Administration, the European Medicines Agency and the Israeli Ministry of Health for the treatment of patients with known or presumed MoCD Type A (discontinued if MoCD Type A is not confirmed), and it is the first and only FDA-approved therapy indicated to reduce the risk of mortality in patients with MoCD Type A. 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.

- The first and only treatment in Europe to treat patients with molybdenum cofactor deficiency (MoCD) Type A, an ultra-rare, life-threatening genetic disorder that often progresses rapidly in infants with a median overall survival age of about four years. - European Commission (EC) decision is based on the efficacy and safety data collected to date compared to data from a natural history study. - NULIBRY was BridgeBio’s first FDA-approved therapeutic; Sentynl acquired global rights to NULIBRY in March 2022. PALO ALTO, Calif. and SOLANA BEACH, Calif. and AHMEDABAD, India, Sept. 20, 2022 (GLOBE NEWSWIRE) -- 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 the European Commission (EC) has granted marketing authorization 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. 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. Following this decision by the EC, NULIBRY is the first and only approved therapy in the European Union (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 European Medicines Agency (EMA) and through approval of NULIBRY’s regulatory submission with the Israeli Ministry of Health. "The European Commission's approval of NULIBRY is an exciting step in delivering this therapy to all children suffering with MoCD Type A worldwide, and it bolsters our belief at BridgeBio that no disease is too rare to address. We are grateful that the European Commission sees the value of this treatment, and to the patients, caregivers, physicians, scientists, and advocates whose efforts made this possible," said BridgeBio founder and CEO Neil Kumar, Ph.D. The EC authorization follows the positive opinion granted by European Committee for Medicinal Products for Human Use (CHMP) in July 2022, which was supported by data from three clinical trials that demonstrated the efficacy of NULIBRY for the treatment of patients with MoCD Type A compared to data from a natural history study. These studies showed that in the genotype-matched analysis, patients treated with NULIBRY had 7.1 times lower risk of death than their historical control counterparts from the natural history study, with 86% of NULIBRY-treated patients surviving at three years compared to 52% of the genotype-matched control group. “The approval of NULIBRY by the European Commission is a promising development for children with MoCD Type A. Zydus Group is committed to making a meaningful difference in the lives of people suffering from rare and orphan diseases. This approval brings us closer to realizing our purpose of empowering people with the freedom to live healthier and more fulfilled lives,” said Dr. Sharvil Patel, Managing Director of Zydus Lifesciences, the parent company of Sentynl Therapeutics. “This is a major milestone for those patients living with MoCD Type A in Europe,” said Matt Heck, CEO of Sentynl. “Marketing authorization is an important step in providing access to NULIBRY and creating awareness of MoCD Type A as many patients are often missed.” The EC's centralized marketing authorization is valid in all EU member states as well as Iceland, Liechtenstein, and Norway. A regulatory filing is expected in the coming months to the UK's Medicine and Healthcare products Regulatory Agency (MHRA) as part of the European Commission Decision Reliance Procedure. Sentynl expects to make NULIBRY available following successful completion of country-by-country health authority discussions. Until such time, NULIBRY will be made available to qualified patients through an Early Access Program. In July 2022, BridgeBio received New Drug Application (NDA) Approval of NULIBRY as a treatment for MoCD Type A from the Israeli Ministry of Health.

PALO ALTO, Calif. and SOLANA BEACH, Calif. and PETACH TIKVA, Israel, Aug. 10, 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.), along with partner Medison Pharma, a global pharmaceutical company focused on providing access to highly innovative therapies to patients in international markets, today announced that the State of Israel Ministry of Health has approved NULIBRY® (fosdenopterin) for Injection as the first therapy in Israel to treat MoCD Type A with the indication to reduce the risk of mortality for 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. Nulibry® (fosdenoptrin) Understanding MoCD Type A "At BridgeBio, we believe that no disease is too rare to address. We are grateful that NULIBRY is now an approved therapy in Israel, and we are focused on ensuring that even more children around the world who suffer with MoCD Type A have access to this treatment," said BridgeBio founder and CEO Neil Kumar, Ph.D. NULIBRY is a cPMP substrate replacement therapy that was approved by the U.S. FDA in February 2021 to reduce the risk of mortality in patients with MoCD Type A. In July 2022 the CHMP recommended that NULIBRY be approved in the EU as a treatment for patients with MoCD Type A. Based on the CHMP recommendation, a decision by the European Commission (EC), which authorizes marketing applications in the EU, is expected on the NULIBRY application later this year. "The approval of NULIBRY in Israel is a promising development for children with MoCD Type A. At Zydus and Sentynl we are driven by the purpose of empowering people with the freedom to live healthier and more fulfilled lives. NULIBRY will bring us closer to realizing our purpose and making a meaningful difference in the lives of children with this rare disorder," said Dr. Sharvil Patel, Managing Director of Zydus Lifesciences, the parent company of Sentynl Therapeutics. "We are very pleased to share the news of the Israeli approval on the heels of receiving the CHMP's recommendation in favor of NULIBRY. We are confident this is only the beginning for patients living with MoCD Type A and we intend to continue advancing our efforts to broaden access to this therapy throughout the world for children in need, while increasing awareness of a disease that has historically been underdiagnosed," said Matt Heck, CEO of Sentynl. The approval by the State of Israel Ministry of Health 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 82% and increased the probability of survival to 84% at three years compared to 55% in the untreated, genotype-matched, historical control group in the natural history study. 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. "We are proud that our partnership with BridgeBio Pharma and Sentynl enables us to provide this highly innovative therapy to babies born with MoCD Type A, a severely progressive genetic disease that results in irreversible neurological damage and eventual death," said Meir Jakobsohn, Founder and CEO of Medison Pharma. "The Israeli Ministry of Health's decision brings us one step closer to accelerating access of this cutting-edge therapy to those in need." In March 2022, Sentynl acquired the global rights to NULIBRY and is responsible for the ongoing development and commercialization of NULIBRY in the U.S. and developing, manufacturing, and commercializing fosdenopterin globally.
