Type C meeting with FDA held in December 2024 to discuss HTT lowering as potential surrogate endpoint to support accelerated approval for PTC518 for HD. The Agency was aligned with the scientific rationale for HTT lowering as a potential surrogate endpoint and asked that PTC provide additional clinical data, such as those being collected in PIVOT-HD, to show associations between HTT lowering and changes in clinical outcome measures. 12-month results from the PIVOT-HD Phase 2 study of PTC518 expected in Q2 2025. Fourth Quarter and Full Year 2024 Financial Highlights: Total revenues were $213.2 million for the fourth quarter of 2024, compared to $307.1 million for the fourth quarter of 2023. Total revenue was $806.8 million for full year 2024, compared to $937.8 million for full year 2023. Total revenue includes net product revenue across the commercial portfolio of $154.7 million for the fourth quarter of 2024 and $601.0 million for full year 2024, compared to $155.1 million for the fourth quarter of 2023 and $661.2 million for full year 2023. Total revenue also includes royalty, collaboration, and manufacturing revenue of $58.5 million in the fourth quarter of 2024 and $205.8 million for full year 2024, compared to $152.0 million for the fourth quarter of 2023 and $276.6 million for full year 2023. Translarna net product revenues were $93.7 million for the fourth quarter of 2024, compared to $75.2 million for the fourth quarter of 2023. Translarna net product revenues were $339.9 million for full year 2024, compared to $355.8 million for full year 2023. Emflaza net product revenues were $50.5 million for the fourth quarter of 2024, compared to $67.4 million for the fourth quarter of 2023. Emflaza net product revenues were $207.2 million for full year 2024, compared to $255.1 million for full year 2023. These results were driven by the expiration of Emflaza's orphan drug exclusivity in February 2024. Roche reported Evrysdi® full year 2024 sales of approximately 1,631 CHF million, resulting in royalty revenue of $203.9 million to PTC for full year 2024, as compared to $168.9 million for full year 2023. Also in the fourth quarter of 2023, PTC recorded a sales milestone of $100.0 million for the achievement of $1.5 billion in worldwide annual net sales from Evrysdi. This sales milestone was recorded as collaboration revenue. Based on U.S. GAAP (Generally Accepted Accounting Principles), GAAP R&D expenses were $124.8 million for the fourth quarter of 2024, compared to $121.4 million for the fourth quarter of 2023. GAAP R&D expenses were $534.5 million for full year 2024, compared to $666.6 million for full year 2023. The slight increase in R&D expense for the fourth quarter of 2024 reflects additional costs due to manufacturing, regulatory filings, and inspections primarily related to Kebilidi and sepiapterin. The decrease in R&D expense for full year 2024 relates to decreases in program spend related to our strategic portfolio prioritization as we continue to focus our resources on our differentiated, high potential research and development programs. R&D expense also included a total of $65.0 million regulatory success-based milestones paid to the former Censa securityholders for the year ended December 31, 2024, as compared to a $30.0 million success-based development milestone payable to the former Censa securityholders for the year ended December 31, 2023. Non-GAAP R&D expenses were $116.0 million for the fourth quarter of 2024, excluding $8.8 million in non-cash, stock-based compensation expense, compared to $113.2 million for the fourth quarter of 2023, excluding $8.1 million in non-cash, stock-based compensation expense. Non-GAAP R&D expenses were $497.9 million for full year 2024, excluding $36.6 million in non-cash, stock-based compensation expense, compared to $613.6 million for full year 2023, excluding $52.9 million in non- cash, stock-based compensation expense. GAAP SG&A expenses were $84.7 million for the fourth quarter of 2024, compared to $76.3 million for the fourth quarter of 2023. GAAP SG&A expenses were $300.9 million for full year 2024, compared to $332.5 million for full year 2023. The increase in SG&A expense for the fourth quarter of 2024 reflects our continued investment to support commercial activities, including expanding our commercial portfolio. The decrease in SG&A expense for full year 2024 was primarily due to lower employee costs as a result of the reduction in the workforce in 2023. Non-GAAP SG&A expenses were $76.3 million for the fourth quarter of 2024, excluding $8.4 million in non-cash, stock-based compensation expense, compared to $67.9 million for the fourth quarter of 2023, excluding $8.4 million in non-cash, stock-based compensation expense. Non-GAAP SG&A expenses were $262.9 million for full year 2024, excluding $38.0 million in non-cash, stock-based compensation expense, compared to $283.8 million for full year 2023, excluding $48.7 million in non- cash, stock-based compensation expense. The change in the fair value of deferred and contingent consideration was a gain of $10.2 million for the fourth quarter of 2024, compared to a gain of $2.7 million for the fourth quarter of 2023. Change in the fair value of deferred and contingent consideration was a gain of $4.5 million for full year 2024, compared to a gain of $127.7 million for full year 2023. The full year 2024 change is primarily related to the Company's strategic portfolio prioritization and decision to discontinue its preclinical and early research programs in its gene therapy platform in May 2023, which included programs for FA and Angelman syndrome. The intangible asset impairment was $159.5 million for the fourth quarter and full year 2024, compared to $0.0 million for fourth quarter and $217.8 million for the full year 2023, which represented a non-cash charge. For the fourth quarter and full year 2024, we impaired $159.5 million related to a decrease in projected cash flows due to refinements in current market assumptions and the timing of patient treatments for AADC. For the full year 2023, we fully impaired the FA and Angelman syndrome intangible assets and recorded impairment expense of $217.8 million. Net loss was $65.9 million for the fourth quarter of 2024, compared to net loss of $155.8 million for the fourth quarter of 2023. Net loss was $363.3 million for full year 2024, compared to net loss of $626.6 million for full year 2023. Cash, cash equivalents, and marketable securities was $1,139.7 million on December 31, 2024, compared to $876.7 million on December 31, 2023. Shares issued and outstanding as of December 31, 2024, were 77,704,188. PTC Full Year 2025 Financial Guidance: PTC anticipates total revenues for full year 2025 to be between $600 million and $800 million, including in-line products, potential new product launches, and royalty revenue from Evrysdi. PTC anticipates GAAP R&D and SG&A expenses for full year 2025 to be between $805 million and $835 million. PTC anticipates non-GAAP R&D and SG&A expenses for full year 2025 to be between $730 million and $760 million, excluding estimated non-cash, stock-based compensation expense of $75 million.

- PDUFA target action date of Aug. 19, 2025 - WARREN, N.J., Feb. 19, 2025 /PRNewswire/ -- PTC Therapeutics, Inc. (NASDAQ: PTCT) announced today that the U.S. Food and Drug Administration (FDA) has accepted for filing the New Drug Application (NDA) for vatiquinone for the treatment of children and adults living with Friedreich's ataxia (FA). The application has been granted Priority Review and assigned a Prescription Drug User Fee Act (PDUFA) target action date of Aug. 19, 2025. "We are excited to be one step closer to bringing an approved therapy to all patients with Friedreich's ataxia," said Matthew B. Klein, M.D., Chief Executive Officer of PTC Therapeutics. "If approved, vatiquinone would be the first therapy for pediatric patients with FA, and provide a potential safe, well-tolerated and effective treatment alternative for adults. The granting of priority review by FDA reflects the significant unmet need for younger patients with FA. We look forward to working collaboratively with FDA during the review process." The vatiquinone NDA is based on data from the placebo-controlled MOVE-FA study as well as results from two long-term studies including pediatric and adult FA patients. Data from these three studies demonstrate significant, durable and clinically meaningful evidence of slowing disease progression on key aspects of disease. In addition, these studies demonstrate that vatiquinone is safe and well tolerated in all age groups studied. The vatiquinone NDA was the fourth approval application submitted to the FDA by PTC in 2024. All four applications were accepted for review. About Vatiquinone Vatiquinone is a small molecule, first-in-class selective inhibitor of 15-Lipoxygenase (15-LO), an enzyme that is a key regulator of the energetic and oxidative stress pathways that are disrupted in Friedreich's ataxia. Inhibition of 15-LO helps to alleviate the consequences of mitochondrial dysfunction and oxidative stress, ultimately decreasing cellular inflammation and oxidative stress and promoting neuronal survival.1,2,3 Vatiquinone has been evaluated in a number of clinical studies, many focused on pediatric patients, and has demonstrated an impact on mortality risk, fatigue, and a number of neurological and neuromuscular disease symptoms. About MOVE-FA MOVE-FA was a global registration-directed trial of vatiquinone that enrolled 146 pediatric, adolescent and adult FA patients, the majority of whom were under 18 years of age. While the primary endpoint of change from baseline in the overall mFARS score did not reach statistical significance (p=0.14), a statistically significant effect (p=0.021) was recorded on the mFARS upright stability subscale, which was a pre-specified endpoint, and the portion of the mFARS now understood to be the most sensitive and relevant for the enrolled primary analysis population. In addition, the effect on upright stability was concordant with favorable treatment effect on the 1-minute walk distance test and the functional component of the Modified Fatigue Rating Scale. The study included a 72-week placebo-controlled phase and a long-term open-label extension. Following completion of MOVE-FA, subjects were eligible to enroll in a long-term, open-label extension study which is ongoing. About Friedreich's Ataxia Friedreich's ataxia (FA) is a rare, physically debilitating, life-shortening, neuromuscular disorder that mainly affects the central nervous system and the heart.4 It is the most common hereditary ataxia (abnormal, uncoordinated movements) and is usually caused by a single genetic defect in the frataxin (FXN) gene that leads to reduced production of frataxin, a mitochondrial protein that is important for cellular metabolism and energy production.4,5 Decreased frataxin levels are associated with mitochondrial iron accumulation and increased oxidative stress, which can lead to cell death through ferroptosis.6,7,8 Symptoms include progressive loss of coordination and muscle strength leading to poor balance and coordination, difficulty speaking, swallowing, and breathing, curvature of the spine, serious heart conditions, diabetes, and hearing and vision impairment.9,10 The severity of symptoms and speed of progression varies between people and some symptoms may not be evident in all. Friedreich's ataxia is usually diagnosed in childhood or adolescence.5,11 Approximately 25,000 people have Friedreich's ataxia globally. About PTC Therapeutics, Inc. PTC is a global biopharmaceutical company that discovers, develops, and commercializes clinically differentiated medicines that provide benefits to children and adults living with rare disorders. PTC's ability to innovate to identify new therapies and to globally commercialize products is the foundation that drives investment in a robust and diversified pipeline of transformative medicines.
