WARREN, N.J., Aug. 8, 2024 /PRNewswire/ -- PTC Therapeutics, Inc., (NASDAQ: PTCT) today announced a corporate update and financial results for the second quarter ending June 30, 2024.

"I am proud of our team's continued outstanding execution as we have accomplished all our objectives so far this year," said Matthew Klein, M.D., Chief Executive Officer. "We are in a strong cash position, submitted three drug approval applications to the FDA and remain on schedule to achieve the many milestones we have set for the remainder of 2024."

Key Corporate Updates:

• Second quarter 2024 total revenue of $187 million
• Second quarter 2024 revenue for the DMD franchise was $118 million

• • Translarna™ (ataluren) net product revenue was $70 million, driven by continued access for patients in existing geographies and continued geographic expansion.
  • Emflaza^® (deflazacort) net product revenue was $47 million, driven by new patient starts and continued brand loyalty.

Key Clinical and Regulatory Milestones:

• PTC submitted an NDA to the FDA for sepiapterin for the treatment of PKU in July 2024. Further regulatory submissions are planned for Japan and Brazil later in 2024.
• PTC resubmitted the NDA for Translarna for the treatment of nmDMD in July 2024.
• PTC achieved all objectives in the interim readout of the Phase 2 PIVOT-HD study of PTC518 in Huntington's disease patients, which were disclosed in the second quarter.
• PTC plans to submit an NDA for vatiquinone for the treatment of Friedreich ataxia in late 2024.
• PTC expects to share topline data for the CardinALS trial of utreloxastat for the treatment of ALS in the fourth quarter of 2024.
• The BLA for PTC's gene therapy for AADC deficiency was accepted by FDA with priority review; the target regulatory action date is November 13, 2024.

Second-Quarter 2024 Financial Highlights:

• Total revenues were $186.7 million for the second quarter of 2024, compared to $213.8 million for the second quarter of 2023.
• Total revenues include net product revenue across the commercial portfolio of $133.2 million for the second quarter of 2024, compared to $174.6 million for the second quarter of 2023. Total revenues also include royalty and manufacturing revenue of $53.5 million for the second quarter of 2024, compared to $39.2 million for the second quarter of 2023.
• Translarna net product revenues were $70.4 million for the second quarter of 2024, compared to $96.5 million for the second quarter of 2023. These results were due to the timing of bulk government orders.
• Emflaza net product revenues were $47.3 million for the second quarter of 2024, compared to $65.7 million for the second quarter of 2023. These results were driven by the expiration of Emflaza's orphan drug exclusivity in February 2024.
• Roche reported Evrysdi 2024 year-to-date sales of approximately CHF 838 million, resulting in royalty revenue of $53.2 million to PTC for the second quarter of 2024, as compared to $36.9 million for the second quarter of 2023.
• Based on U.S. GAAP (Generally Accepted Accounting Principles), GAAP R&D expenses were $132.2 million for the second quarter of 2024, compared to $185.9 million for the second quarter of 2023. The decrease in quarterly research and development expenses reflects strategic portfolio prioritization as PTC continues to focus its resources on its differentiated, high-potential programs. Included in second quarter 2024 R&D expense is a $15.0 million regulatory success-based milestone related to the Censa acquisition.
• Non-GAAP R&D expenses were $122.7 million for the second quarter of 2024, excluding $9.4 million in non-cash, stock-based compensation expense, compared to $170.3 million for the second quarter of 2023, excluding $15.5 million in non-cash, stock-based compensation expense.
• GAAP SG&A expenses were $69.5 million for the second quarter of 2024, compared to $88.4 million for the second quarter of 2023. The decrease in quarterly selling, general and administrative expenses reflects lower employee costs due to the reduction in workforce in 2023.
• Non-GAAP SG&A expenses were $59.7 million for the second quarter of 2024, excluding $9.8 million in non-cash, stock-based compensation expense, compared to $74.6 million for the second quarter of 2023, excluding $13.8 million in non-cash, stock-based compensation expense.
• Change in the fair value of deferred and contingent consideration was a loss of $5.1 million for the second quarter of 2024, compared to a gain of $128.9 million for the second quarter of 2023. The change in fair value of contingent consideration is primarily related to the strategic portfolio prioritization and the decision to discontinue the Friedreich ataxia and Angelman syndrome gene therapy programs in the second quarter of 2023. As a result, PTC determined that the fair value for all of the contingent consideration payable related to Friedreich ataxia and Angelman syndrome was $0 and recorded a gain of $129.8 million.
• Tangible asset impairment and losses (gains) on transactions, net, was a loss of $1.8 million for the second quarter of 2024, compared to $0 million for the second quarter of 2023. These results were due to the sale of certain assets related to gene therapy manufacturing and fixed asset impairments, partially offset by a gain on lease terminations and a gain on sales of certain fixed assets.
• Net loss was $99.2 million for the second quarter of 2024, compared to net loss of $198.9 million for the second quarter of 2023.
• Cash, cash equivalents, and marketable securities was $1,093.3 million on June 30, 2024, compared to $876.7 million on December 31, 2023. During the second quarter of 2024, PTC amended its agreement with Royalty Pharma and exercised one of its put options in exchange for $250 million in cash, less royalties received.
• Shares issued and outstanding as of June 30, 2024, were 76,900,123.
