Release Details

SOUTH PLAINFIELD, N.J., Aug. 7, 2018 /PRNewswire/ -- PTC Therapeutics, Inc. (NASDAQ: PTCT) today announced a corporate update and reported financial results for the second quarter ending June 30, 2018.

"We have made significant progress towards delivering on our strategic plan this year," said Stuart W. Peltz, Ph.D., Chief Executive Officer, PTC Therapeutics, Inc. "This includes furthering our underlying business as well as executing on two external transactions. We look forward to bringing value to both patients and shareholders with the acquisition of Agilis, the LATAM commercialization rights for Tegsedi™ and Waylivra™ and realizing additional growth in the second half of the year."

Second Quarter Financial Highlights:

• Total revenues for the second quarter of 2018 were $68.7 million, compared to $48.0 million in the same period in 2017. The change in total revenue was a result of Emflaza®, which launched in May 2017, and the expanded commercialization of Translarna™.
• Translarna net product revenues were $47.8 million for the second quarter of 2018, representing 4% growth over $45.8 million reported in the second quarter of 2017.
• Emflaza net product revenues were $20.3 million for the second quarter of 2018, from $2.1 million reported in the second quarter of 2017.
• GAAP R&D expenses were $32.6 million for the second quarter of 2018, compared to $30.8 million for the same period in 2017. Non-GAAP R&D expenses were $28.7 million for the second quarter of 2018, excluding $3.9 million in non-cash, stock-based compensation expense, compared to $26.9 million for the same period in 2017, excluding $3.9 million in non-cash, stock-based compensation expense. The increase in GAAP and non-GAAP R&D expense was primarily due to increased investment in research programs and advancement of the clinical pipeline.
• GAAP SG&A expenses were $33.5 million for the second quarter of 2018, compared to $28.9 million for the same period in 2017. Non-GAAP SG&A expenses were $29.4 million for the second quarter of 2018, excluding $4.1 million in non-cash, stock-based compensation expense, compared to $24.9 million for the same period in 2017, excluding $4.0 million in non-cash, stock-based compensation expense. The increase in GAAP and non-GAAP SG&A expense was primarily due to continued investment in commercial activities to support the Duchenne muscular dystrophy franchise.
• Net loss for the second quarter of 2018 was $9.5 million, compared to a net loss of $17.5 million for the same period in 2017.
• In April 2018, PTC completed a public offering of 4,600,000 shares of common stock, resulting in net offering proceeds of $117.9 million.
• Cash, cash equivalents, and marketable securities totaled approximately $296.1 million at June 30, 2018, compared to approximately $191.2 million at December 31, 2017.
• Shares issued and outstanding as of June 30, 2018 were 46.7 million.

2018 Guidance

• Full year 2018 net product revenues are anticipated to be between $260 and $295 million. PTC anticipates Translarna net product revenue for the full year 2018 to be between $170 and $185 million. PTC projects a 5-year (December 31, 2022) compound annual growth rate of 15% for net product revenues, representing continued strong growth year-over-year by increasing penetration in current countries and pursuing opportunities for label expansion. PTC anticipates Emflaza net product revenue for the full year 2018 to be between $90 and $110 million.
• GAAP R&D and SG&A expense for the full year 2018 is anticipated to be between $280 and $290 million.
• Non-GAAP R&D and SG&A expense for the full year 2018 is anticipated to be between $250 and $260 million, excluding estimated non-cash, stock-based compensation expense of approximately $30 million.

Key Second Quarter and Other Corporate Highlights:

• Agreement to acquire Agilis Biotherapeutics gene therapy platform and four CNS clinical assets diversify and strengthen PTC's existing pipeline. Following successful completion of the transaction, PTC plans a smooth transition of operations and to rapidly accelerate the programs. PTC plans to submit a Biologics Licensing Application with FDA in 2019 for the lead program in AADC deficiency, based on compelling long-term clinical data. An IND submission to the U.S. FDA is expected in 2019 for the second lead program in Friedreich ataxia. The transaction is expected to close in the third quarter of 2018.
• In-licensed LATAM commercial rights to Tegsedi™ (inotersen) and Waylivra ™ (volanesorsen) from Akcea Therapeutics. The collaboration leverages PTC's global commercial infrastructure and adds to growing commercial pipeline. Tegsedi has received marketing authorization approval from the European Commission for the treatment of stage 1 or stage 2 polyneuropathy in adult patients with hereditary transthyretin amyloidosis (hATTR amyloidosis). PTC estimates that there are approximately 6,000 patients in LATAM and that it is well positioned to file for registration in key countries in LATAM for Tegsedi. Tegsedi has a PDUFA date of October 6, 2018. Waylivra is under regulatory review in the U.S., Europe and Canada for the treatment of people with familial chylomicronemia syndrome (FCS). Waylivra recently received a positive vote from the FDA'sDivision of Metabolism and Endocrinology Products Advisory Committee and has a PDUFA date of August 30, 2018. Waylivra is also in clinical development for Familial Partial Lipodystrophy, or FPL.
• Compelling data from FIREFISH study and advancement of SMA clinical programs. Data presented at the CureSMA conference demonstrated that at Day 182, over 90% of the babies in the FIREFISH study achieved a greater than 4-point increase in CHOP-INTEND score compared to baseline. The CHOP-INTEND data were further supported by video presented by the investigator in which babies demonstrated improved motor function including head control, rolling from supine, and sitting. Three babies were depicted sitting independently. Updated SMA data including additional sitting babies from part 1 of the FIREFISH study will be presented at the upcoming World Muscle Congress. Part 2 of the pivotal FIREFISH study is ongoing. SUNFISH, a pivotal trial in Type 2/3 SMA patients is also ongoing.
• European Commission ratifies CHMP's positive opinion for the label expansion of Translarna for children as young as 2 years of age. The authorization allows PTC to market Translarna for the treatment of nonsense mutation Duchenne muscular dystrophy in ambulatory patients aged two years and older in the 28 countries that are Member States of the European Union, as well as European Economic Area members Iceland, Liechtenstein and Norway.
• Focus on intensifying the conversion of Emflaza bridge patients. There are currently hundreds of patients who have been prescribed Emflaza for whom commercial shipments were not yet made. PTC plans to intensify the efforts and programs to expedite the conversion of those prescriptions to commercial shipment in the second half of the year.
• Publication of additional data demonstrating the clinically differentiated benefit of deflazacort. The results published in Muscle and Nerve demonstrated Duchenne muscular dystrophy patients treated with deflazacort had notably less decline from baseline in 6-minute walk distance at Week 48 than those treated with prednisone/prednisolone. The extrapolated time to loss of ambulation was 8.58 years for deflazacort and 4.74 years with prednisone/prednisolone. In addition to the time to delay of loss of ambulation, patients on deflazacort demonstrated a slowing of disease progression as measured by physical function endpoints.
