– First-quarter 2023 total revenue of $220 million, representing 48% year-over-year growth -

– Readouts from four clinical studies expected in second quarter of 2023, three of which are registration-directed – 

  

SOUTH PLAINFIELD, N.J., April 27, 2023 – PTC Therapeutics, Inc. (NASDAQ: PTCT) today announced a corporate update and financial results for the first quarter ending March 31, 2023.  

 

“We are pleased to report strong revenue growth in the first quarter, with double-digit year-over-year revenue increases for all six of our marketed and partnered products,” said Matthew Klein, M.D., Chief Executive Officer, PTC Therapeutics, Inc. “In addition, we remain on track to share readouts from four clinical studies, including three registration-directed studies, in the second quarter.”    

Key Corporate Updates:  

First quarter 2023 revenue for the Duchenne muscular dystrophy (DMD) franchise was $170 million, representing 33% year-over-year growth
oTranslarna™ (ataluren) quarterly net product revenue was $115 million, with growth coming from treatment of new patients, continued high compliance and continued geographic expansion
oEmflaza® (deflazacort) quarterly net product revenue was $55 million, driven by new patients, high compliance and broader access

Key Clinical and Regulatory Updates:  

PTC continues to make progress in ongoing registration-directed clinical studies:   
oThe APHENITY Phase 3 trial of sepiapterin (PTC923) for PKU, with results anticipated in May 2023
oThe MIT-E Phase 2/3 vatiquinone trial for mitochondrial disease associated seizures, with results anticipated in the second quarter of 2023
oThe MOVE-FA Phase 3 vatiquinone trial for Friedreich ataxia, with results anticipated in the second quarter of 2023
Enrollment in the PIVOT-HD Phase 2 trial of PTC518 for Huntington’s disease is active and ongoing at study sites in Europe and Australia. Interim data from the first 12 weeks of the placebo-controlled trial is anticipated in the second quarter of 2023.
Given the anticipated imminent results from these studies, PTC will not be discussing these programs from April 28 until results are disclosed for each study.
For Upstaza, the FDA requested additional bioanalytical data in support of comparability analyses between the clinical and commercial drug product. We have received initial feedback from the FDA on these data and are in the process of responding to additional queries prior to submitting the BLA, which could result in a BLA submission occurring in the third quarter of 2023.
PTC submitted a Type II variation to EMA to support the conversion of the conditional marketing authorization for Translarna to a standard marketing authorization. PTC expects a CHMP opinion in the second quarter of 2023.

First Quarter 2023 Financial Highlights:

Total revenues were $220.4 million for the first quarter of 2023, compared to $148.7 million for the first quarter of 2022.
Total revenue includes net product revenue across the commercial portfolio of $187.6 million for the first quarter of 2023, compared to $129.8 million for the first quarter of 2022. Total revenue also includes collaboration, royalty and manufacturing revenue of $32.8 million in the first quarter of 2023, compared to $18.9 million for the first quarter of 2022.

Translarna net product revenues were $115.1 million for the first quarter of 2023, compared to $79.2 million for the first quarter of 2022. These results were driven by treatment of new patients, continued high compliance and geographic expansion.
Emflaza net product revenues were $54.6 million for the first quarter of 2023, compared to $48.6 million for the first quarter of 2022. These results reflect new patients, high compliance, and broader access.
Roche reported Evrysdi 2023 year to date sales of approximately CHF 363 million, resulting in royalty revenue of $30.8 million to PTC for the first quarter of 2023, as compared to $18.9 million for the first quarter of 2022.
Based on U.S. GAAP (Generally Accepted Accounting Principles), GAAP R&D expenses were $195.1 million for the first quarter of 2023, compared to $140.1 million for the first quarter of 2022. The increase reflects additional investment in research programs and advancement of the clinical pipeline. The increase in R&D expenses includes the achievement of a $30.0 million success-based development milestone for the completion of enrollment of a Phase 3 clinical trial for sepiapterin for PKU.
Non-GAAP R&D expenses were $179.8 million for the first quarter of 2023, excluding $15.3 million in non-cash, stock-based compensation expense, compared to $127.0 million for the first quarter of 2022, excluding $13.0 million in non-cash, stock-based compensation expense.
GAAP SG&A expenses were $86.9 million for the first quarter of 2023, compared to $73.3 million for the first quarter of 2022. The increase reflects our continued investment to support commercial activities, including expanding our commercial portfolio.
Non-GAAP SG&A expenses were $73.4 million for the first quarter of 2023, excluding $13.5 million in non-cash, stock-based compensation expense, compared to $59.7 million for the first quarter of 2022, excluding $13.6 million in non-cash, stock-based compensation expense.
Change in the fair value of deferred and contingent consideration was a loss of $2.4 million for the first quarter of 2023, compared to a gain of $11.7 million for the first quarter of 2022. The change in fair value of deferred and contingent consideration is related to the fair valuation of potential future consideration to be paid to former equity holders of Agilis Biotherapeutics, Inc. (Agilis) in connection with PTC’s acquisition of Agilis, which closed in August 2018.
Net loss was $139.0 million for the first quarter of 2023, compared to net loss of $126.7 million for the first quarter of 2022.

Non-GAAP Financial Measures:

In this press release, the financial results of PTC are provided in accordance with GAAP and using certain non-GAAP financial measures. In particular, the non-GAAP R&D and SG&A expense financial measures exclude non-cash, stock-based compensation expense. These non-GAAP financial measures are provided as a complement to financial measures reported in GAAP because management uses these non-GAAP financial measures when assessing and identifying operational trends. In management's opinion, these non-GAAP financial measures are useful to investors and other users of PTC's financial statements by providing greater transparency into the historical and projected operating performance of PTC and the company's future outlook. Non-GAAP financial measures are not an alternative for financial measures prepared in accordance with GAAP. Quantitative reconciliations of the non-GAAP financial measures to their respective closest equivalent GAAP financial measures are included in the table below.

The forward-looking statements contained herein represent PTC's views only as of the date of this press release and PTC does not undertake or plan to update or revise any such forward-looking statements to reflect actual results or changes in plans, prospects, assumptions, estimates or projections, or other circumstances occurring after the date of this press release except as required by law.
