"The first half of the year was a very exciting time for PTC. We successfully completed an IPO raising gross proceeds of more than $144 million. With over $165 million in cash on our balance sheet at the end of the quarter, we are now well capitalized to continue the late-stage clinical development of our lead product candidate, ataluren, in nonsense mutation Duchenne muscular dystrophy and cystic fibrosis," said Stuart Peltz, PhD, Chief Executive Officer, PTC Therapeutics, Inc. "We began enrolling patients in our Phase 3 nmDMD clinical trial earlier this year and we plan to begin enrollment in our Phase 3 nmCF clinical trial in the first half of 2014.  We are also excited about the progress that is being made in our SMA program that is partnered with Roche where we recently announced the selection of a development candidate."

Key Recent Accomplishments

• Successful Completion of Initial Public Offering (IPO): In June 2013, PTC completed its IPO selling approximately 9.6 million shares of common stock at a public offering price of $15 per share, resulting in approximately $144.4 million in gross proceeds to the company, before deducting underwriting discounts and commissions and other offering expenses.
• Initiated Confirmatory Phase 3 Study of Ataluren in nmDMD: In April 2013, PTC initiated a confirmatory Phase 3 clinical trial evaluating ataluren as a potential treatment for patients with Duchenne muscular dystrophy due to a nonsense mutation (nmDMD). The study is on-track to complete enrollment by mid-2014 with country approvals for the trial and clinical trial site initiation proceeding according to plan. The Phase 3 study is expected to be conducted at 53 clinical sites across 18 countries.
• Submitted Responses to Day 120 Questions for MAA Submission: Following the October 2012 submission of a Marketing Authorization Application (MAA) to the European Medicines Agency (EMA) for conditional approval of ataluren in nmDMD, the EMA provided a list of questions to PTC regarding its application, known as the Day 120 Questions. In July 2013, PTC submitted responses to the Day 120 Questions to the EMA. The company anticipates a response from the Committee for Medicinal Products for Human Use, or CHMP, on the MAA submission for conditional approval of ataluren for the treatment of nmDMD by the end of 2013.
• Selected Lead Candidate for SMA Program: On August 8, 2013, in collaboration with its partners, the SMA Foundation and Roche, PTC declared a lead development candidate in the spinal muscular atrophy (SMA) program. Selection of the development candidate triggered a $10 million milestone payment by Roche to PTC, which will be recognized as revenue in the third quarter of 2013. This milestone is important for moving this program forward and evidences the value of PTC's splicing platform technology.

Second Quarter 2013 Financial Highlights

• Cash, cash equivalents, and marketable securities totaled $165.7 million at June 30, 2013 compared to $2.7 million at December 31, 2012.
• Total operating expenses increased to $21.3 million for the second quarter of 2013, including $1.9 million in stock based compensation expense, from $15.1 million for the second quarter of 2012, including $0.6 million in stock based compensation expense. The increase was primarily due to higher research and development expenses related to the initiation of the Phase 3 clinical trial of ataluren for the treatment of nmDMD, as well as higher general and administrative expenses related to public company expenses and pre-commercial activities.
• Net loss attributable to common shareholders for the second quarter of 2013 was $14.6 million compared to a net income attributable to common shareholders for the second quarter of 2012 of $153.5 million. In 2012, the company recorded a gain of $160.0 million on exchange of convertible preferred stock in connection with a recapitalization. 
• In July 2013, the company paid in full the outstanding principal and interest balance of $2.6 million under promissory notes issued related to a secured debt facility with a syndicate of two lenders.
