Amino Acid Metabolism, Inborn Errors

- BLA submitted to FDA for Upstaza™ for the treatment of AADC deficiency - - NDA to be submitted mid-year for Translarna™ based on FDA feedback - SOUTH PLAINFIELD, N.J., March 19, 2024 /PRNewswire/ -- PTC Therapeutics, Inc. (NASDAQ: PTCT) today announced the submission of a BLA to the U.S. FDA for Upstaza™ (eladocagene exuparvovec), a gene therapy for the treatment of aromatic L-amino acid decarboxylase (AADC) deficiency. In addition, based on recent feedback from the FDA, PTC plans to re-submit an NDA for Translarna™ (ataluren) for the treatment of nonsense mutation Duchenne muscular dystrophy (nmDMD). PTC expects to make the NDA resubmission by mid-year. "We are excited to bring Upstaza one step closer to children in the United States with the highly mortal and fatal disease of AADC deficiency. The data collected to date continue to demonstrate the transformative clinical benefits the gene therapy provides to patients," said Matthew B. Klein, M.D., Chief Executive Officer of PTC Therapeutics. "In addition, we look forward to the Translarna NDA resubmission this summer. We know U.S. patients and families have been waiting for an approved therapy that specially targets nmDMD." In addition, the sepiapterin MAA for PKU remains on schedule for submission to the EMA by the end of this month. About Upstaza™ (eladocagene exuparvovec) Upstaza is a one-time gene replacement therapy indicated for the treatment of patients aged 18 months and older with a clinical, molecular, and genetically confirmed diagnosis of aromatic L–amino acid decarboxylase (AADC) deficiency with a severe phenotype. It is a recombinant adeno-associated virus serotype 2 (AAV2)-based gene therapy, containing the human DDC gene.1 It is designed to correct the underlying genetic defect, by delivering a functioning DDC gene directly into the putamen, increasing the AADC enzyme and restoring dopamine production.2,3 The efficacy and safety profile of Upstaza has been demonstrated across clinical trials and compassionate use programs.1 The first patient was dosed in 2010. In clinical trials, Upstaza demonstrated transformational neurological improvements. The most common side effects were initial insomnia, irritability and dyskinesia. Administration of Upstaza occurs through a stereotactic surgical procedure, a minimally invasive neurosurgical procedure used for the treatment of a number of pediatric and adult neurological disorders. The Upstaza administration procedure is performed by a qualified neurosurgeon in centers specialized in stereotactic neurosurgery. Upstaza has received marketing authorization in Europe, Great Britain and Israel. About aromatic L-amino acid decarboxylase (AADC) deficiency AADC deficiency is a fatal, rare genetic disorder that typically causes severe disability and suffering from the first months of life, affecting every aspect of life – physical, mental and behavioral. The suffering of children with AADC deficiency may be exacerbated by: episodes of distressing seizure-like oculogyric crises causing the eyes to roll up in the head, frequent vomiting, behavioral problems, and difficulty sleeping. The lives of affected children are severely impacted and shortened. Ongoing physical, occupational and speech therapy, and interventions, including surgery, also are often required to manage potentially life-threatening complications such as infections, severe feeding and breathing problems. About Translarna™ (ataluren) Translarna (ataluren), discovered and developed by PTC Therapeutics, is a protein restoration therapy designed to enable the formation of a functioning protein in patients with genetic disorders caused by a nonsense mutation. A nonsense mutation is an alteration in the genetic code that prematurely halts the synthesis of an essential protein. The resulting disorder is determined by which protein cannot be expressed in its entirety and is no longer functional, such as dystrophin in Duchenne. Translarna, the tradename of ataluren, is licensed in multiple countries for the treatment of nonsense mutation Duchenne muscular dystrophy (nmDMD) in ambulatory patients aged 2 years and older. Ataluren is an investigational new drug in the United States. About Duchenne Muscular Dystrophy (Duchenne) Primarily affecting males, Duchenne is a rare and fatal genetic disorder that results in progressive muscle weakness from early childhood and leads to premature death in the mid-20's due to heart and respiratory failure. It is a progressive muscle disorder caused by the lack of functional dystrophin protein. Dystrophin is critical to the structural stability of all muscles, including skeletal, diaphragm, and heart muscles. Patients with Duchenne can lose the ability to walk (loss of ambulation) as early as 10 years old, followed by loss of the use of their arms. Duchenne patients subsequently experience life-threatening lung complications, requiring the need for ventilation support, and heart complications in their late teens and 20s.
