Ablynx [Euronext Brussels: ABLX] and AbbVie [NYSE: ABBV] today announced that they have entered into a global license agreement to develop and commercialize the anti-IL-6R Nanobody, ALX-0061, to treat inflammatory diseases. ALX-0061 is Ablynx’s proprietary anti-IL-6R Nanobody that successfully completed a Phase IIa study in February 2013 reporting strong efficacy and safety data in patients with moderately to severely active rheumatoid arthritis (RA) on a stable background of methotrexate.

Under the terms of the agreement, Ablynx will be responsible for completing Phase II clinical development in both RA and systemic lupus erythematosus (SLE). Upon the achievement of pre-defined success criteria, AbbVie will exercise its right to in-license ALX-0061 and be responsible for subsequent Phase III clinical development and commercialization. Ablynx will retain an option for co-promotion rights in Belgium, the Netherlands and Luxembourg. Ablynx will receive an upfront payment of $175 million, which will partly be used to fund the next phases of clinical development of ALX-0061. Upon achievement of certain development, regulatory, commercial and sales-based milestones, Ablynx will be eligible to receive additional milestone payments totalling up to $665 million as well as double-digit tiered royalties on net sales upon commercialization.

“This deal represents a major milestone for Ablynx and confirms both the potential value of ALX-0061 and the ability of our Nanobody technology to generate clinical candidates with very exciting potential,” said Edwin Moses, Ph.D., chairman and chief executive officer, Ablynx. “It also demonstrates that we are delivering on our business model of strategic partnering for the development and commercialization of selected programs within our pipeline. We truly believe that AbbVie’s significant expertise in rheumatology aligns us with the ideal partner to further progress the development of ALX-0061 and to ensure we maximize the potential of this asset.”

Dr. Moses added, “the combined clinical expertise of AbbVie and Ablynx will allow us to progress with the rapid development of ALX-0061, with the current plan being the initiation of various clinical trials in both RA and SLE during the course of 2014 and 2015. We look forward to working together with AbbVie to potentially develop a successful therapy for patients suffering from chronic inflammatory conditions and to making a real difference to the quality of their lives.”

“This agreement is further evidence of AbbVie’s commitment to pursue novel treatment options for autoimmune diseases,” said Scott Brun, M.D., vice president, pharmaceutical development, AbbVie. “Anti-IL-6 antibodies are a proven mechanism of action for autoimmune diseases and ALX-0061 has shown potential in a Phase IIa clinical trial in RA. We are looking forward to working with Ablynx to develop a potentially new and effective therapy for patients suffering from serious chronic conditions such as RA and SLE.”

About ALX-0061

ALX-0061 targets the interleukin 6 pathway via its IL-6 receptor (IL-6R), which plays a key role in the inflammation process in RA. ALX-0061 has been designed to become a best-in-class therapeutic. Its small size (26kD) may potentially allow ALX-0061 to penetrate more effectively into tissues. The potent, monovalent interaction of the molecule with its target reduces the possibility of off-target effects. Its binding to human serum albumin prolongs the in vivo half-life of the product and can lead to improved trafficking to areas of inflammation. The Nanobody has a very strong affinity for soluble IL-6R which should ensure fast target engagement and could result in a fast onset of effect. ALX-0061 appears to benefit from the general Nanobody characteristic of having a very low immunogenic potential.

About RA and SLE

RA is characterized by chronic and progressive joint inflammation that typically results in permanent, debilitating tissue damage, which is further compounded by joint deformation. The condition is associated with lower quality of life, premature death, disability, and unemployment. It is estimated that up to 1 percent of the adult population worldwide suffer from RA.

SLE is a complex, multi-organ, autoimmune disorder characterized by the production of pathogenic autoantibodies and tissue deposition of immune complexes, which result in widespread tissue damage. Although the etiology of SLE is not fully understood, multiple genetic, environmental, and hormonal factors have been implicated in its development. The disease displays a broad variety of symptoms and highly variable clinical features, including systemic, cutaneous, renal, musculoskeletal, and haematological manifestations. Approximately 5 million people worldwide suffer from a form of lupus and 90 percent of people diagnosed are women.

Conference call and webcast presentation

The Ablynx management team will host a conference call and webcast during which the licensing deal with AbbVie will be presented, followed by a Q&A session. This event will be held today, Sept. 23, 2013 at 4.00 pm CET/ 10 am ET. The conference call will be webcast live and may be accessed on the home page of the Ablynx website at www.ablynx.com. If you would like to participate in the Q&A, please dial +32 (0)2 620 0138, confirmation code 7195500. Shortly after the call, a replay of the webcast and the presentation used in connection with the conference call webcast will be available on Ablynx’s website.
