Akcea and Pfizer Inc. announce licensing agreement for investigative antisense therapy AKCEA-ANGPTL3-LRx

PfizerAkcea Therapeutics, Inc. (NASDAQ: AKCA), a majority-owned affiliate of Ionis Pharmaceuticals, Inc. (NASDAQ: IONS) and Pfizer Inc. (NYSE:PFE), today announced that the companies have entered into a worldwide exclusive licensing agreement for AKCEA-ANGPTL3-LRx, an investigational antisense therapy being developed to treat patients with certain cardiovascular and metabolic diseases.

AKCEA-ANGPTL3-LRx is designed to reduce the production of angiopoietin-like 3 (ANGPTL3) protein in the liver, a key regulator of triglycerides, cholesterol, glucose and energy metabolism. AKCEA-ANGPTL3-LRx is currently being evaluated in a Phase 2 study in patients with Type 2 diabetes, hypertriglyceridemia and non-alcoholic fatty liver disease (NAFLD).

"AKCEA-ANGPTL3-LRx has the potential to treat people suffering from certain cardiovascular and metabolic diseases. Given the unmet medical need for this patient population and the broad market potential, we believe Pfizer's expertise and breadth of experience in cardiovascular and metabolic diseases makes it well suited to accelerate clinical development of AKCEA-ANGPTL3-LRx, and to deliver it to patients in need of additional therapies for these life threatening diseases," said Damien McDevitt, Ph.D., interim chief executive officer at Akcea.

"Pfizer is committed to delivering breakthrough medicines to patients with unmet medical needs," said Mikael Dolsten, Chief Scientific Officer and President, Worldwide Research & Development and Medical, Pfizer. "AKCEA-ANGPTL3-LRx is a novel therapy that will complement our clinical mid-stage internal medicine pipeline, and we believe that our deep expertise in cardiovascular and metabolic diseases will help allow this program to reach its maximum potential for patients."

Under terms of the agreement, Akcea and Ionis will receive a $250 million upfront license fee, which will be split equally between the two companies. Akcea will settle its $125 million obligation to Ionis in Akcea common stock. The companies are also eligible to receive development, regulatory and sales milestone payments of up to $1.3 billion and tiered, double-digit royalties on annual worldwide net sales following marketing approval of AKCEA-ANGPTL3-LRx. Future milestone payments and royalties will be split equally between Akcea and Ionis. Pfizer is responsible for all development and regulatory activities and costs beyond those associated with the ongoing Phase 2 study. Prior to regulatory filing for marketing approval, Akcea has the right, at its option to participate in certain commercialization activities with Pfizer in the U.S. and certain additional markets on pre-defined terms and based on meeting pre-defined criteria.

This transaction is subject to clearance under the Hart-Scott Rodino Antitrust Improvements Act and other customary closing conditions.

About AKCEA-ANGPTL3-LRx

AKCEA-ANGPTL3-LRx is an investigational antisense therapy being developed to treat patients with certain cardiovascular and metabolic diseases. This antisense medicine is designed to reduce the production of angiopoietin-like 3 (ANGPTL3) protein in the liver, a key regulator of triglycerides, cholesterol, glucose and energy metabolism. AKCEA-ANGPTL3-LRx was developed using Ionis' advanced LIgand Conjugated Antisense (LICA) technology platform. The potential therapeutic benefits of ANGPTL3 reduction are supported by the discovery that people with a genetic deficiency in ANGPTL3 have reduced levels of low-density lipoprotein cholesterol (LDL-C) and triglycerides, and a decreased risk of diabetes and cardiovascular disease(1). In a Phase 1/2 study, patients treated with AKCEA-ANGPTL3-LRx achieved robust, dose-dependent reductions of ANGPTL3, triglycerides, LDL-cholesterol and total cholesterol with a positive safety and tolerability profile(2). AKCEA-ANGPTL3-LRx is currently being evaluated in a Phase 2 study in patients with Type 2 diabetes, hypertriglyceridemia and non-alcoholic fatty liver disease (NAFLD). AKCEA-ANGPTL3-LRx was discovered by Ionis and has been co-developed by Akcea and Ionis.
