Published: Aug 02, 2018

SOUTH PLAINFIELD, N.J. and CAMBRIDGE, Mass., Aug. 2, 2018 /PRNewswire/ -- PTC Therapeutics, Inc. (NASDAQ: PTCT), and Akcea Therapeutics, Inc. (NASDAQ: AKCA), an affiliate of Ionis Pharmaceuticals, Inc. (NASDAQ: IONS), today announced a collaboration under which PTC will commercialize two of Akcea's rare disease drugs in Latin America (LATAM): TEGSEDI™ (inotersen) and WAYLIVRA™ (volanesorsen).

TEGSEDI has received marketing authorization approval from the European Commission (EC) for the treatment of stage 1 or stage 2 polyneuropathy in adult patients with hereditary transthyretin amyloidosis (hATTR amyloidosis). TEGSEDI is also the subject of a pending new drug application in the U.S. and Canada. 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's Division 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.

"This collaboration reflects our strategic initiative to leverage PTC's global infrastructure and reflects our successes in bringing innovative drugs to patients in Latin America," said Stuart W. Peltz, Ph.D., chief executive officer, PTC Therapeutics. "We are excited to work with Akcea as part of the global launch and commercialization of TEGSEDI and WAYLIVRA."

"One of the key mutations that leads to hATTR amyloidosis occurs more frequently in individuals of Portuguese descent," stated Marcio Souza, chief operating officer, PTC Therapeutics, Inc. "There are approximately 6,000 patients with polyneuropathic hATTR amyloidosis in Latin America, making it a strategically important region for TEGSEDI. We are well positioned to file for registration in key Latin American countries in the short term."

"Our decision to partner with PTC to accelerate commercial access for patients in Latin America reflects our commitment to bringing TEGSEDI and WAYLIVRA to patients as rapidly as possible," said Paula Soteropoulos, chief executive officer, Akcea Therapeutics. "PTC's established rare disease team in Latin America has a proven record of success in patient identification, in physician and patient education and support programs and in efficiently obtaining market access. PTC's patient-focused approach for rare diseases aligns with ours and will be important as we bring TEGSEDI and WAYLIVRA to patients in this region."

Key Transaction Details
Under the agreement, PTC will gain exclusive rights to TEGSEDI and WAYLIVRA in Latin America and certain Caribbean countries. PTC will pay Akcea an upfront licensing fee of $18 million, $12 million which is due on signing and $6 million which will be paid on the earlier of FDA or EMA approval of WAYLIVRA. In addition, PTC will pay Akcea regulatory milestones in the PTC territory up to a total of $8 million. Akcea is also eligible to receive royalties from PTC in the mid-twenty percent range on net sales of each drug in the PTC territory. PTC's obligation to pay Akcea royalties begins on the earlier of 12 months after the first commercial sale of a product in Brazil or the date that PTC recognizes revenue of at least $10 million in LATAM. The collaboration will be governed by a joint steering committee with representation from both parties. Akcea gained the global rights to TEGSEDI and WAYLIVRA through licenses from Ionis. Milestone payments and royalties that Akcea receives from PTC for TEGSEDI will be split 60% to Ionis and 40% to Akcea. All WAYLIVRA milestone payments and royalties that Akcea receives from PTC will be split 50/50 with Ionis.

About TEGSEDITM (inotersen)
TEGSEDITM (inotersen), a product of Ionis' proprietary antisense technology, is an antisense oligonucleotide (ASO) inhibitor of human transthyretin (TTR) production and was developed by Ionis. TEGSEDI is the world's first RNA-targeted therapeutic to treat patients with hATTR amyloidosis. TEGSEDI is approved in the E.U. for the treatment of stage 1 or stage 2 polyneuropathy in adult patients with hereditary transthyretin amyloidosis (hATTR) and is currently under regulatory review in the U.S. and Canada. For important safety information for TEGSEDI, including method of administration, special warnings, drug interactions and adverse drug reactions, please see the European Summary of Product Characteristics (SmPC), available from the EMA website at www.ema.europa.eu.

About hereditary transthyretin (hATTR) amyloidosis
hATTR amyloidosis is a progressive, systemic and fatal inherited disease caused by the abnormal formation of the TTR protein and aggregation of TTR amyloid deposits in various tissues and organs throughout the body, including in peripheral nerves, heart, intestinal tract, eyes, kidneys, central nervous system, thyroid and bone marrow. The progressive accumulation of TTR amyloid deposits in these tissues and organs leads to sensory, motor and autonomic dysfunction often having debilitating effects on multiple aspects of a patient's life. Patients with hATTR amyloidosis often present with a mixed phenotype and experience overlapping symptoms of polyneuropathy and cardiomyopathy.

Ultimately, hATTR amyloidosis results in death within three to fifteen years of symptom onset. Therapeutic options for the treatment of patients with hATTR amyloidosis are limited and there are currently no disease-modifying drugs approved for the disease. There are an estimated 50,000 patients with hATTR amyloidosis worldwide. Additional information on hATTR amyloidosis, including a full list of organizations supporting the hATTR amyloidosis community worldwide, is available at www.hattrchangethecourse.com.

About WAYLIVRATM (volanesorsen)
WAYLIVRATM, a product of Ionis' proprietary antisense technology, is under regulatory review in the U.S., E.U. and Canada as a treatment for familial chylomicronemia syndrome (FCS). The U.S. and E.U. regulatory agencies have granted Orphan Drug Designation to WAYLIVRA for the treatment of FCS. If approved, WAYLIVRA would be the first and only therapy indicated for people with FCS.

About Familial Chylomicronemia Syndrome (FCS)
FCS is an ultra-rare disease caused by impaired function of the enzyme lipoprotein lipase (LPL) and characterized by severe hypertriglyceridemia (>880mg/dL) and a risk of unpredictable and potentially fatal acute pancreatitis. Because of limited LPL function, people with FCS cannot breakdown chylomicrons, lipoprotein particles that are 90% triglycerides. In addition to pancreatitis, FCS patients are at risk of chronic complications due to permanent organ damage. They can experience daily symptoms including abdominal pain, generalized fatigue and impaired cognitions that affect their ability to work. People with FCS also report major emotional and psychosocial effects including anxiety, social withdrawal, depression and brain fog. There is no effective therapy for FCS currently available. Additional information on FCS is available at www.fcsfocus.com, and through the FCS Foundation at http://www.livingwithfcs.org and the LPLD Alliance at www.lpldalliance.org.
