Third Quarter Financial Highlights:
•
Total revenues for the third quarter of 2018 were $53.6 million, compared to $41.9 million in the same period in 2017. The change in total revenue was primarily a result of revenue from Emflaza, which launched in May 2017.
•
Translarna net product revenues were $30.4 million for the third quarter of 2018, compared to $32.0 million reported in the third quarter of 2017.

Emflaza net product revenues were $22.6 million for the third quarter of 2018, compared to $9.8 million reported in the third quarter of 2017.

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, as well as the Akcea Therapeutics, Inc.

compensation expense, compared to $27.9 million for the same period in 2017, excluding $3.5 million in non-cash, stock-based compensation expense.

Completed acquisition of Agilis Biotherapeutics adding a Central Nervous System (CNS) gene therapy platform. Acquisition included three programs in rare CNS disorders including Aromatic L-Amino Acid Decarboxylase (AADC), Friedreich Ataxia and Angelman Syndrome. PTC plans to file a biologics license application (BLA) in AADC in 2019. Pre-commercial efforts, such as patient identification efforts are ongoing. PTC estimates that there are 5,000 AADC deficiency patients worldwide with 1,200 patients in the United States. In addition, PTC plans to file an investigational new drug application (IND) in Friedreich Ataxia in 2019.

•
PTC in-licensed Latin America commercial rights to Tegsedi and Waylivra leverages strong commercial expertise. Tegsedi has been approved in the United States, European Union, and Canada for the treatment of stage 1 or stage 2 polyneuropathy in adult patients with hereditary transthyretin amyloidosis (hATTR). The polyneuropathic form of hATTR, occurs more frequently in individuals of Portuguese ancestry, where PTC estimates approximately 6,000 patients in Latin America are affected. PTC has started patient identification efforts and plan to submit an application for Tegsedi with ANVISA, the Brazilian regulatory authority in the first half of 2019.
•
Initial STRIDE registry data demonstrates that Translarna delays loss of ambulation. Preliminary data from the first international drug registry for Duchenne patients receiving Translarna demonstrated participants continuing to walk years longer and are remaining more physically able than untreated children. The data confirms Translarna’s long-term clinical benefit in delaying irreversible muscle loss in patients and was presented to experts at the 23rd International Annual Congress of the World Muscle Society.
•
Pursing label expansion with European Medicines Agency (EMA) for Translarna for non-ambulatory patients. In the third quarter, PTC filed for an extension of its existing label for Translarna to include non-ambulatory patients. The EMA has validated the application and the regulatory process is ongoing.
•
Continued advancement of the spinal muscular atrophy (SMA) program. Data demonstrating the clinical benefits of risdiplam in all types of SMA were presented at the 23rd International Annual Congress of the World Muscle Society. Babies from FIREFISH Part 1 study showed increased functional developmental milestones including sitting. The pivotal portion of FIREFISH is enrolling. Clinical data was presented for the first time for the Type 2 & 3 patients from the open label portion of SUNFISH demonstrating a median 3-point increase in motor function score which was supported by the increase of SMN protein measured in the blood. The pivotal portion of SUNFISH Part 2 study in Type 2 & 3 patients has completed enrollment.
•
Development in oncology program with two clinical advancements. PTC initiated a Phase 1 study evaluating the safety of PTC596 in patients with diffuse intrinsic pontine glioma (DIPG). Additionally, the PTC299 study is now actively enrolling patients in acute myeloid leukemia (AML).
