CELG acquires (private) Delinia for $300M up-front and $475M in contingent payments: http://finance.yahoo.com/news/celgene-acquire-delinia-inc-120000484.html The transaction expands Celgene’s Inflammation and Immunology pipeline through the acquisition of Delinia’s lead program, DEL106, as well as related second generation programs. DEL106 is a novel IL-2 mutein Fc fusion protein designed to preferentially upregulate regulatory T cells (Tregs), immune cells that are critical to maintaining natural self-tolerance and immune system homeostasis. Augmenting Tregs as a means of restoring immune system balance has the potential to benefit patients with a variety of autoimmune diseases such as systemic lupus erythematosus and rheumatoid arthritis.
