|Humira, its uses and side effects
NEWS 2008 Bayer Healthcare LLC, a unit of Bayer AG (BAYG.DE) filed a
patent-infringement lawsuit in a U.S. court against Abbott Laboratories
(ABT.N) relating to the drug Humira on Dec 24. 
Bayer Healthcare said Abbott's drug infringes on a 1997 Bayer patent
"Human Anti-TNF Antibodies." The patent covers antibodies that fight a
protein called "tumor necrosis factor" (TNF), that causes inflammation.
Humira is used to treat certain patients with arthritis, psoriasis, Crohn's
Disease and a form of arthritis called ankylosing spondylitis. 
Humira is an injectable drug for treating multiple immune system-related
diseases, including rheumatoid and ankylosing spondylitis (a type of
arthritis) the intestinal disorder Crohn's disease and the skin condition
plaque psoriasis. Abbott has projected that Humira sales will exceed $4.4
billion in the year of 2008. 
Abbott said there is no infringement issue because Abbott believes that
Bayer's patent is invalid.  The Bayer patent in question, No. 5,654,407,
covers a genetically engineered antibody that binds to and blocks the
action of a type of immune system cell called tumor necrosis factor, or TNF.
TNF is one of the cytokines, the "messengers" of the immune system, and
stimulates inflammation, a key problem in the conditions that Humira treats.
