– PTC strengthened its financial position following recent restructuring initiatives and Royalty Pharma transaction –

SOUTH PLAINFIELD, N.J., Oct. 26, 2023 /PRNewswire/ -- PTC Therapeutics, Inc., (NASDAQ: PTCT) today announced a corporate update and financial results for the third quarter ending September 30, 2023.

“I am very proud of the progress all of our teams made this quarter,” said Matthew Klein, M.D., Chief Executive Officer, PTC Therapeutics, Inc. “The recent Royalty Pharma transaction and restructuring initiatives that we implemented have put the company on a strong financial footing. We believe we are well positioned to deliver on our most promising opportunities for growth, including the potential sepiapterin revenue opportunity of more than $1 billion and the PTC518 HD program.”

Key Corporate Updates:

• Finalized strategic partnership transaction with Royalty Pharma, in which Royalty Pharma acquired additional royalties of Evrysdi for $1.0 billion upfront. The agreement included options for PTC to sell the remainder of its royalties of Evrysdi for up to $500 million or for Royalty Pharma to acquire half of such retained royalties for up to $250 million at a later date, less royalties received by PTC. PTC maintains all economics associated with up to $250 million in the remaining commercial sales milestones associated with Evrysdi global net sales.
• Third quarter 2023 revenue for the DMD franchise was $136 million, supporting increasing 2023 DMD franchise revenue guidance to between $565 million and $595 million.
  • Translarna™ (ataluren) quarterly net product revenue was $69 million, with new patients in existing geographies and continued geographic expansion.
  • Emflaza^® (deflazacort) quarterly net product revenue was $67 million, with new patient starts and high compliance.

Key Clinical and Regulatory Updates:

• For Translarna, following the negative opinion from the CHMP, the CHMP gave PTC the option to request re-examination of both opinions or only one opinion. PTC decided to pursue re-examination of the negative opinion on renewal of the conditional authorization only. In accordance with EMA guidelines, PTC expects the opinion from the re-examination procedure in late January 2024, with ratification of that opinion by the European Commission 67 days later.
• For the United States, a type C meeting with the FDA for Translarna is scheduled for the fourth quarter of 2023.
• PTC held a pre-NDA meeting in the third quarter with the FDA for sepiapterin in PKU to discuss the NDA submission. At the meeting, the FDA stated that the sepiapterin clinical safety and efficacy data supported NDA submission for the treatment of pediatric and adult PKU patients. It was requested that PTC complete an additional 26-week nonclinical mouse study to assess sepiapterin carcinogenicity potential prior to NDA submission. This nonclinical study was not initially required when sepiapterin was acquired from Censa, as the NDA submission was planned under the Section 505(b)(2) pathway. With PTC’s decision to file under the Section 505(b)(1) pathway, the 26-week study is considered a required NDA component needed to inform labeling and is typically completed prior to submission. PTC will continue to discuss with the FDA the potential to submit the mouse study results during the NDA review process. PTC now expects the NDA submission to occur no later than the third quarter of 2024; the submission could be submitted during the second quarter of 2024 if the nonclinical study report can be submitted during the review process.
• PTC expects to submit an MAA to the EMA for sepiapterin for the treatment of PKU in the first half of 2024.
• Enrollment in the PIVOT-HD study for PTC518 for Huntington’s disease continues outside of the US for both the stage 2 and early stage 3 cohorts. PTC expects the next data update to occur in the first half of 2024. This update will include 12-month data on the initial group of subjects for which data was reported in June of this year.
• PTC had a type A meeting with the FDA to discuss the clinical safety data needed to enable enrollment of the PIVOT-HD trial at US study sites. At the meeting, the FDA stated that the existing three months of safety data could support 12-week dosing at 5mg and 10mg dose levels and that six months of clinical safety data demonstrating a similar favorable safety profile could support 12-month dosing in PIVOT-HD.
• PTC had a type C written-response-only meeting with FDA for vatiquinone for Friedreich ataxia to determine whether the data from the MOVE-FA study would be sufficient to support an NDA for accelerated approval. In their written response, the FDA stated that while they see the value of upright stability as a clinically meaningful endpoint, they believed a confirmatory study would likely be needed to support NDA submission. PTC has requested a follow-up live meeting to address the issues raised by the FDA.
• PTC is participating in a scientific advice procedure with the EMA to determine if the MOVE-FA data could support a conditional marketing authorization application in the EEA. PTC expects to have the outcome of this procedure in the first quarter of 2024.
• PTC had an informal meeting with the FDA for Upstaza for AADC deficiency. The FDA stated that the data PTC has provided to support comparability between the clinical drug product and the intended commercial drug product were still not sufficient. The FDA did say that the available data from the ongoing clinical study in the US assessing the safety of the drug delivery cannula could be used to support a BLA for accelerated approval based on biomarker data demonstrating a treatment-related increase in de novo dopamine production. The FDA suggested that PTC conduct a pre-BLA meeting prior to BLA submission to review BLA contents. This meeting has been scheduled for December 2023, and pending the outcome, PTC expects to submit the BLA shortly thereafter.

• The change in the fair value of deferred and contingent consideration was a loss of $1.5 million for the third quarter of 2023, compared to a gain of $5.3 million for the third quarter of 2022.
• The net loss was $133.0 million for the third quarter of 2023, compared to a net loss of $109.3 million for the third quarter of 2022.
