GHENT/ZWIJNAARDE, Belgium, March 17, 2015 (GLOBE NEWSWIRE) -- Ablynx [Euronext Brussels: ABLX; OTC: ABYLY] today announced that it has administered the first dose in the Phase IIb study to evaluate the efficacy and safety of its anti-IL-6R Nanobody®, ALX-0061, administered subcutaneously in combination with methotrexate (MTX) in adult patients with active RA, despite MTX therapy. The study aims to identify the optimum dose and frequency of administration of ALX-0061 for the next phases of development.
In September 2013, Ablynx and AbbVie entered into a global license agreement, worth up to US$840 million plus double-digit royalties, to develop and commercialise ALX-0061. As part of the agreement, Ablynx is responsible for Phase II clinical development of ALX-0061 in both RA and systemic lupus erythematosus (SLE).
The current Phase IIb study is a multi-centre, randomised, double-blind, placebo-controlled dose-range finding study of ALX-0061, administered subcutaneously in combination with MTX (a commonly used first-line DMARD1 agent for patients with RA), in subjects with moderate to severe RA, despite MTX therapy. The study is expected to enrol 330 subjects in the United States, Europe and South America, who will be randomly assigned to placebo or four different dose groups of ALX-0061 administered subcutaneously. Administration will be performed every 2 weeks or every 4 weeks. Subjects will be followed for efficacy up to and including week 24 and for safety up to and including week 34. Following completion of the 24-week study, eligible subjects will be invited to participate in an open-label extension study.
The primary endpoint is the ACR20 response2 at week 12, a broadly accepted clinical response measure to demonstrate reduction in RA signs and symptoms. The secondary endpoints include higher level of response assessments, documentation of efficacy of ALX-0061 over time, as well as of the effects of ALX-0061 on the improvement in physical function and health-related quality of life. Other planned assessments include the determination of ALX-0061 levels, biomarkers, safety, tolerability and immunogenicity.
Dr Edwin Moses, CEO of Ablynx, commented:
“Ablynx and our partner AbbVie are committed to making ALX-0061 available for people living with rheumatoid arthritis. The start of this first Phase IIb study in this chronic and progressive disease is therefore an important milestone. The programme is progressing according to plan and we expect top line results from the study before the end of 2016. If the results meet pre-defined success criteria, AbbVie will exercise its right to in-license ALX-0061 and be responsible for subsequent Phase III clinical development and commercialisation.”
About ALX-0061
ALX-0061 targets the interleukin 6 pathway via its IL-6 receptor (IL-6R) and has been developed for the treatment of RA and possibly systemic lupus erythematosus (SLE). IL-6 is a pro-inflammatory cytokine that plays a role in T-cell activation, production of acute phase proteins in response to inflammation, induction of immunoglobulin production, and stimulation of osteoclast differentiation and activation. ALX-0061 (26kD) has a very strong affinity for the soluble IL-6R and contains an anti-IL-6R Nanobody linked to an anti-human serum albumin (HSA) Nanobody, thereby increasing the in vivo serum half-life. Phase I/II proof-of-concept results with ALX-0061 were published in February 2013, followed by the signing of a global exclusive licensing deal with AbbVie in September 2013 for the development and commercialisation of ALX-0061.
About RA and SLE
RA is characterised 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 characterised by the production of pathogenic autoantibodies and tissue deposition of immune complexes, which result in widespread tissue damage. Although the aetiology 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.
