- 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.

Investigator-Sponsored Phase 2 Study Demonstrated Positive Results for VOXZOGO in Children with Hypochondroplasia New Analyses Highlight VOXZOGO 7-year Data and Improvement on Quality of Life in Children with Achondroplasia SAN RAFAEL, Calif., March 12, 2024 /PRNewswire/ -- BioMarin Pharmaceutical Inc. (Nasdaq: BMRN) announced that positive early results from an investigator-sponsored Phase 2 study of VOXZOGO® (vosoritide) in children with hypochondroplasia, will be presented at the 2024 American College of Medical Genetics and Genomics (ACMG) Annual Clinical Genetics Meeting in Toronto, Canada, March 12-16, 2024. Researchers will also present data from Phase 2 and Phase 3 studies of the medicine in children with achondroplasia, including results that demonstrate VOXZOGO's positive impact on quality of life. Results in Hypochondroplasia Andrew Dauber, M.D., will present positive results from his investigator-sponsored Phase 2 study of VOXZOGO in children with hypochondroplasia. The annualized growth velocity (AGV) increased from 5.12 cm/year during the observation period to 6.93 cm/year during the treatment period (mean difference: 1.81 cm/year, p<0.0001). No new safety signals were reported. "We are encouraged by preliminary results from the first study evaluating VOXZOGO in children with hypochondroplasia, suggesting the medicine has the potential to impact growth outcomes for this group of patients," said Dr. Dauber, who is the lead study author and Chief of Endocrinology at Children's National Hospital in Washington, D.C. "There are currently no approved medicines for children with hypochondroplasia, so we look forward to gathering additional data to deepen our understanding of VOXZOGO in hypochondroplasia and other growth-related conditions." In late 2023, BioMarin launched the pivotal clinical trial program studying the safety and efficacy of VOXZOGO in children with hypochondroplasia. A multinational observational study in children with hypochondroplasia (111-902) is currently recruiting participants, and the company plans to enter the treatment phase (Phase 3 trial) later this year. New Data Highlights VOXZOGO Long-Term Efficacy, Safety and Quality of Life in Achondroplasia 7-year Phase 2 Results in Achondroplasia Data from two studies of VOXZOGO in children ≥5 years of age with achondroplasia demonstrated a sustained improvement in AGV for each year that the participants were treated. In the Phase 2 study with more than 7 years of follow up, the mean increase in growth across each year of age up to 16 years compared with untreated participants was 1.63 cm/year for boys and 1.33 cm/year for girls. Separate cross-sectional comparative analysis assessing increase in height over a 7-year period showed an additional height gain of 11.03 cm with use of VOXZOGO compared to matched untreated children over the same period. 4-year Phase 3 Results in Achondroplasia The same analyses were produced for the Phase 3 trial in which children with achondroplasia have a mean treatment follow-up of 4 years. The mean increase in growth across each year of age up to 17 years was 1.73 cm/year for boys and 1.46 cm/year for girls. A separate cross-sectional comparative analysis assessing increase in height over a 3-year period showed an additional height gain of 5.75 cm with use of VOXZOGO compared to matched untreated children over the same period. 3-year Phase 3 Quality of Life Results in Achondroplasia Results from a separate analysis of the Phase 3 study showed that VOXZOGO improved health-related quality of life (HRQoL) among children with achondroplasia, particularly those associated with physical activities. After 3 years, the mean increase in Quality of Life in Short Stature Youth (QoLISSY) physical domain score was 6.0 as reported by caregivers and 6.3 as reported by children. These improvements were even more pronounced in children who grew more (for those with ≥ 1 SD increase in height z-score, the mean increase in physical domain score was 11.4 as reported by caregivers and 8.5 as reported by children). "The clinical results at ACMG reinforce the long-term benefit we are seeing in children treated with VOXZOGO, with a meaningful median height gain of more than 11 cm in children with achondroplasia following 7 years of treatment," said Hank Fuchs, M.D., president of Worldwide Research and Development at BioMarin. "We are particularly encouraged by new data demonstrating the potential impact height gains from VOXZOGO can have on quality of life, an outcome of incredible importance for children and families impacted by achondroplasia." "Achondroplasia can have a negative effect on a child's quality of life, including physical, social and emotional aspects," said Melita Irving, M.D., study investigator and consultant clinical geneticist at Guy's and St. Thomas' NHS Foundation Trust in London. "Our studies showed that increasing height with long-term administration of VOXZOGO can result in meaningful improvements in quality-of-life measures for children with achondroplasia."

VOXZOGO, a C-type natriuretic peptide (CNP) analog, acts as a positive regulator of the signaling pathway downstream of FGFR3 to promote endochondral bone growth. VOXZOGO is approved in the U.S. and indicated to increase linear growth in children with achondroplasia with open epiphyses. This indication is approved under accelerated approval based on an improvement in annualized growth velocity. Continued approval may be contingent upon verification and description of clinical benefit in confirmatory trial(s). To fulfill this post-marketing requirement, BioMarin intends to use the ongoing open-label extension studies compared to available natural history.

About Achondroplasia Achondroplasia, the most common form of skeletal dysplasia leading to disproportionate short stature in humans, is characterized by slowing of endochondral ossification, which results in disproportionate short stature and disordered architecture in the long bones, spine, face, and base of the skull. This condition is caused by a change in the FGFR3 gene, a negative regulator of bone growth. More than 80% of children with achondroplasia have parents of average stature and have the condition as the result of a spontaneous gene mutation. The worldwide incidence rate of achondroplasia is about one in 25,000 live births. VOXZOGO is being tested in children whose growth plates are still "open," typically those under 18 years of age. Approximately 25% of people with achondroplasia fall into this category. VOXZOGO U.S. Important Safety Information What is VOXZOGO used for? VOXZOGO is a prescription medicine used to increase linear growth in children with achondroplasia and open growth plates (epiphyses). VOXZOGO is approved under accelerated approval based on an improvement in annualized growth velocity. Continued approval may be contingent upon verification and description of clinical benefit in confirmatory trials. What is the most important safety information about VOXZOGO? VOXZOGO may cause serious side effects including a temporary decrease in blood pressure in some patients. To reduce the risk of a decrease in blood pressure and associated symptoms (dizziness, feeling tired, or nausea), patients should eat a meal and drink 8 to 10 ounces of fluid within 1 hour before receiving VOXZOGO. What are the most common side effects of VOXZOGO? The most common side effects of VOXZOGO include injection site reactions (including redness, itching, swelling, bruising, rash, hives, and injection site pain), high levels of blood alkaline phosphatase shown in blood tests, vomiting, joint pain, decreased blood pressure, and stomachache. These are not all the possible side effects of VOXZOGO. Ask your healthcare provider for medical advice about side effects, and about any side effects that bother the patient or that do not go away. How is VOXZOGO taken? VOXZOGO is taken daily as an injection given under the skin, administered by a caregiver after a healthcare provider determines the caregiver is able to administer VOXZOGO. Do not try to inject VOXZOGO until you have been shown the right way by your healthcare provider. VOXZOGO is supplied with Instructions for Use that describe the steps for preparing, injecting, and disposing VOXZOGO. Caregivers should review the Instructions for Use for guidance and any time they receive a refill of VOXZOGO in case any changes have been made. Inject VOXZOGO 1 time every day, at about the same time each day. If a dose of VOXZOGO is missed, it can be given within 12 hours from the missed dose. After 12 hours, skip the missed dose and administer the next daily dose as usual. The dose of VOXZOGO is based on body weight. Your healthcare provider will adjust the dose based on changes in weight following regular check-ups. Your healthcare provider will monitor the patient's growth and tell you when to stop taking VOXZOGO if they determine the patient is no longer able to grow. Stop administering VOXZOGO if instructed by your healthcare provider. What should you tell the doctor before or during taking VOXZOGO? Tell your doctor about all of the patient's medical conditions including If the patient has heart disease (cardiac or vascular disease), or if the patient is on blood pressure medicine (anti-hypertensive medicine). If the patient has kidney problems or renal impairment. If the patient is pregnant or plans to become pregnant. It is not known if VOXZOGO will harm the unborn baby.
