<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&#147;We are off to a strong start this year. In our first full quarter since the commercial launch, we have seen strong support for access to Translarna, the first treatment for nonsense mutation Duchene Muscular Dystrophy. We now have 82 patients on commercial therapy, nearly double the number on treatment since our last earnings call,&#148; stated Stuart W. Peltz, Ph.D., Chief Executive Officer, PTC Therapeutics,&nbsp;Inc. &#147;Our goal is to bring Translarna to patients across the globe as quickly as possible and we are pleased to have grown our commercial footprint to approximately 25 countries to date. We are also actively establishing our US infrastructure, in preparation for our anticipated US launch.&#148;</font></p>

Top-line data from the company&#146;s ongoing Phase 3 ACT DMD trial is expected in the fourth quarter of this year which should form the basis for finalizing the NDA submission. Concurrently, PTC has begun building out its US commercial team and infrastructure in preparation for a potential US launch in the first half of 2016. Most recently, PTC announced the hiring of Eric Pauwels as head of commercial operations in the Americas.</font></p>

The trial is being conducted at approximately 90 clinical sites globally and is expected to enroll approximately 208 patients by the end of 2015. PTC intends to file for approval of Translarna for the treatment of nonsense mutation cystic fibrosis in the EU in the second half of 2015.</font></p>

Because of its mechanism of action, Translarna has the potential to address numerous disorders caused by a nonsense mutation. PTC continues to evaluate additional indications to fully capture Translarna&#146;s potential.</font></p>

Since the SMN2 gene in healthy volunteers is the same as in SMA patients, these results demonstrate proof of mechanism based on the expected pharmacodynamic effect.&#160; The Phase 1 clinical study was completed in the spring of 2014 and was well tolerated at all dose levels studied.</font></p>

RG7800 was well tolerated and preliminary review of the blinded data indicates substantial increases in full length SMN2 mRNA. Long term preclinical animal data have recently shown an eye finding at concentrations above those explored in patients. This finding was not observed in humans. As a precautionary measure, the collaboration partners decided to temporarily suspend dosing of additional patients to evaluate this finding and confirm next steps for MOONFISH.</font></p>

Total Translarna product sales in first quarter 2015 includes $1.4 million of revenue which was deferred during 2014 when we recognized revenue on a cash basis. As of January&nbsp;1, 2015, we began recognizing revenue for Translarna as product is shipped, given we have established a pattern of collectability.&#160; This compared to total revenue in the first quarter of 2014 of approximately $9.2 million. The decrease in total revenue was due to receipt of a milestone payment of $7.5 million from Roche recognized in the first quarter of 2014 related to our SMA collaboration, partially offset by Translarna product sales.</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">PTC is a global biopharmaceutical company focused on the discovery, development and commercialization of orally administered, proprietary small molecule drugs targeting an area of RNA biology we refer to as post-transcriptional control. Post-transcriptional control processes are the regulatory events that occur in cells during and after a messenger RNA, or mRNA, molecule is copied from DNA through the transcription process. PTC&#146;s internally discovered pipeline addresses multiple therapeutic areas, including rare disorders, oncology and infectious diseases. PTC has discovered all of its compounds currently under development using its proprietary technologies. PTC plans to continue to develop these compounds both on its own and through selective collaboration arrangements with leading pharmaceutical and biotechnology companies.

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Translarna, discovered and developed by PTC Therapeutics,&nbsp;Inc., is a protein restoration therapy designed to enable the formation of a functioning protein in patients with genetic disorders caused by a nonsense mutation. A nonsense mutation is an alteration in the genetic code that prematurely halts the synthesis of an essential protein. The resulting disorder is determined by which protein cannot be expressed in its entirety and is no longer functional, such as dystrophin in Duchenne muscular dystrophy. Translarna is licensed in the European Economic Area for the treatment of nonsense mutation Duchenne muscular dystrophy in ambulatory patients aged five years and older. Translarna is an investigational new drug in the United States. The development of Translarna has been supported by grants from Cystic Fibrosis Foundation Therapeutics Inc. (the nonprofit affiliate of the Cystic Fibrosis Foundation); Muscular Dystrophy Association; FDA&#146;s Office of Orphan Products Development; National Center for Research Resources; National Heart, Lung, and Blood Institute; and Parent Project Muscular Dystrophy.</font></p>
