– PDUFA target action date of November 13, 2024 –
WARREN, NJ, USA I May 14, 2024 I PTC Therapeutics, Inc. (NASDAQ: PTCT) announced today that the FDA has accepted for filing the Biologics License Application (BLA) for Upstaza™ (eladocagene exuparvovec), a gene therapy for the treatment of AADC deficiency. The application has been granted Priority Review with a target regulatory action date of November 13, 2024.
“We are excited to be one step closer to bringing an approved therapy to patients with AADC deficiency in the United States,” said Matthew B. Klein, M.D., Chief Executive Officer, PTC Therapeutics. “The data collected to date continue to support the transformative benefit of Upstaza, this highly innovative gene therapy directly infused into the brain.”
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.
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.
