"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-0061ALX-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.
