SOUTH PLAINFIELD, N.J., – Jan. 7, 2019 – PTC Therapeutics, Inc. (NASDAQ: PTCT) today provided a corporate update, which will be detailed as part of the company’s presentation at the 37th Annual J.P. Morgan Healthcare Conference on Tuesday, January 8th at 5:00 p.m. PT. Stuart W. Peltz, Ph.D., PTC’s Chief Executive Officer, will highlight the company’s growth and diversification focused on bringing clinically differentiated, life-changing treatments to patients affected by rare disorders. Additionally, an overview of the company’s strategic vision will be provided as well as preliminary 2018 financial results and 2019 financial guidance. The presentation will be webcast live on the Events and Presentations page under the investors’ section of PTC Therapeutics’ website at www.ptcbio.com.

Corporate Highlights

Advancing gene therapy portfolio
PTC plans to submit a BLA with the FDA followed by an MAA in Europe for the AADC deficiency gene therapy program in 2H 2019 with expected launch in 2020. Identification of patients with AADC deficiency has been a priority for the Company, with approximately 100 patients identified to date in the U.S. and Europe. PTC expects to screen about 100,000 patients who are at risk for AADC deficiency before the regulatory approval to maximize patient benefit at time of launch.
Friedreich's ataxia program is advancing with an expected IND filing and entry into the clinic in 2019.
PTC is enhancing its internal research and in-house manufacturing capabilities with fully dedicated resources to maximize current and future programs.


Risdiplam regulatory filing progress. The SMA program is a collaboration between PTC, Roche and SMA Foundation.



Successfully completed enrollment of pivotal portion of FIREFISH trial in Type 1 SMA babies in 2018.
Regulatory submission targeted for the second half of 2019 based on recent feedback from the FDA & national health authorities in Europe that Part 1 of FIREFISH and SUNFISH may be sufficient to file NDA/MAA.
The goal of the clinical development program is to support the approval of a broad label so risdiplam can potentially benefit as many SMA patients as possible.
Short- and long-term cash milestones to PTC expected upon regulatory approval and commercial launches. PTC expects the peak annual royalties/milestones from risdiplam to exceed $200M.

Expanding commercial platform
TEGSEDI™ application filed with ANVISA- Brazilian regulatory authority. ANVISA granted priority review. PTC expects approval in Brazil by year end 2019. TEGSEDI has the potential to generate peak revenues of approximately $150M in LATAM.
Duchenne franchise expected to continue to grow over the next 5 years. Translarna ex-U.S. launch in patients 2 to 5 years of age now initiated. Non-ambulatory label expansion is currently under EMA regulatory review. Emflaza® continues to accrue new patients in the U.S. with expected increased market share gained via differentiation and improved market access.
In recent interactions, the FDA invited PTC to submit a supplementary NDA (sNDA) for Emflaza for patients 2 to 5 years of age on the basis that existing data support its safety and efficacy in this population. PTC recently submitted the sNDA for potential approval in 2019. The previous written request from the FDA that a trial in patients 2 to 5 years of age be performed has been officially withdrawn and the trial will no longer be conducted. PTC now expects to launch Emflaza in this younger population before the end of 2019.

Growing pipeline and R&D capabilities
PTC’s alternative splicing platform has generated another development candidate. PTC258 was selected as a development candidate for Familial dysautonomia (FD), a rare genetic neurological disorder that effects the sensory and autonomic nervous systems, causing life-threatening medical complications from birth. PTC258 is advancing to IND enabling studies with the goal to enter the clinic in late 2019. This program is in collaboration with MGH and NYU.
Translarna’s dystrophin study was initiated in 4Q 2018 for potential U.S. regulatory submission in early 2020.
PTC’s oncology portfolio continues to advance with the initiation of a study in AML with PTC299 and a DIPG study for PTC596. PTC expects these studies to move to the expanded cohort stage in 2020. PTC596 is also being developed for the treatment of patients with Leiomyosarcoma (LMS) with the first patient in that trial expected to be dosed in Q1 2019.




Preliminary Unaudited 2018 Financial Results
PTC expects to report Translarna™ (ataluren) net product revenue for the treatment of nonsense mutation Duchenne muscular dystrophy (nmDMD) of approximately $171 million for full year 2018, an increase of 18% over the prior year.
PTC expects to report EMFLAZA® (deflazacort) net product revenue for the treatment of Duchenne muscular dystrophy (DMD) of approximately $91 million for full year 2018, an increase from $28.8 million in the prior year.
PTC expects to report year-end cash and cash equivalents of approximately $227 million.

PTC is currently in the process of finalizing its financial results for the 2018 fiscal year. The above information is based on preliminary unaudited information and management estimates for the full year 2018, subject to the completion of PTC's financial closing procedures. In addition, the above information is subject to revision as PTC completes its financial closing procedures for fiscal 2018.

2019 Guidance
PTC anticipates full year net product revenues to be between $285 and $305 million.
PTC anticipates GAAP R&D and SG&A expense for the full year 2019 to be between $395 and $405 million.
PTC anticipates Non-GAAP R&D and SG&A expense for the full year 2019 to be between $360 and $370 million, excluding estimated non-cash, stock-based compensation expense of approximately $35 million.


Non-GAAP Financial Measures:
In this press release, the financial results and financial guidance of PTC are provided in accordance with accounting principles generally accepted in the United States (GAAP) and using certain non-GAAP financial measures. In particular, the non-GAAP financial measure excludes non-cash, stock-based compensation expense. This non-GAAP financial measure is provided as a complement to financial measures reported in GAAP because management uses this non-GAAP financial measure when assessing and identifying operational trends. In management's opinion, this non-GAAP financial measure is 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. A quantitative reconciliation of the non-GAAP financial measure to its closest equivalent GAAP financial measure is included in the table below.

Everyone has a different definition of progress. For the last 20 years, we’ve measured our progress researching rare disease in moments. Smiling ones and crying ones. Moments spent with our boys’ families and ones with their friends. We know that every step forward comes after several steps backward, because we’ve lived it—whether spending time with families in their homes or with our scientists researching in our labs. It can be easy to lose yourself as you progress further. Although we’ve grown, our heart remains in the same place, because we’ve never measured ourselves like larger companies do. Our biggest accomplishment has always been the time we can give to all of our families. Whether it’s hours, days, months, or years, every small moment is a big win.
