Simponi the first biologic therapy to be approved for rheumatologic diseases !

We did know about the three 3 TNF inhinitors (namely-Infliximab, Etanercept and Adalimumab), the last still to be approved by US.

Like Infliximab and Etanercept, Adalimumab binds to TNFα preventing it from activating TNF receptors; adalimumab was constructed from a fully human monoclonal antibody, while infliximab is a mouse-human chimeric antibody and etanercept is a TNF receptor-IgG fusion protein. TNFα inactivation has proven to be important in down regulating the inflammatory reactions associated with autoimmune diseases. As of 2008 adalimumab has been approved by the FDA for the treatment of rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, Crohn's disease, moderate to severe chronic psoriasis and juvenile idiopathic arthritis.

Humira (brand name is an abbreviation of "Human Monoclonal Antibody in Rheumatoid Arthritis") is marketed in both preloaded 0.8 ml syringes and also in preloaded pen devices (called Humira Pen), both injected subcutaneously, typically by the patient at home. It cannot be administered orally, because the digestive system would destroy the drug. But its now the turn of Golimumab, a new fully human monoclonal antibody. Being a fully human MAb directed against TNF, Golimumab resembles Adalimumab (Humira, Abbott), which was the first such product to reach the market. Now the Canadian government has approved Golimumab along with ‘methotrexate’ for the treatment of three forms of Rheumatiod arthritis (Rheumatoid Arthritis, Ankylosing Spondylitis & Psoriatic Arthritis) and more over making this treatment the first biologic therapy to be approved.

With this approval in Canada, Simponi (Golimumb), in combination with methotrexate (MTX), is indicated for reducing the signs and symptoms in adult patients with moderately to severely active RA; reducing signs and symptoms in adult patients with moderately to severely active PsA, alone or in combination with MTX; and reducing signs and symptoms in adult patients with active AS who have had an inadequate response to conventional therapies.
