FDA Advisory Committee Recommends Approval of Actemra (tocilizumab) for the Treatment of Rheumatoid Arthritis

First interleukin-6 (IL-6) inhibitor to offer new therapeutic option for rheumatoid arthritis

NUTLEY, N.J., July 29, 2008 /PRNewswire/ -- Roche today announced that the Arthritis Advisory Committee of the U.S. Food and Drug Administration (FDA) by a near unanimous (10-1) vote recommended approval of Actemra (tocilizumab), a novel interleukin-6 (IL-6) receptor-inhibiting monoclonal antibody, for reducing the signs and symptoms in adults with moderate to severe rheumatoid arthritis (RA).

"The committee's overwhelmingly positive recommendation brings Actemra one step closer to becoming available to patients who suffer from the painful and debilitating symptoms associated with RA," said Kenneth Bahrt, M.D., Global Medical Director, Autoimmunity, Roche. "Based on the strength of the data presented, and the positive recommendation by the committee, we are hopeful that the FDA will approve Actemra for the treatment of RA and provide a new option to patients who are not achieving adequate symptom relief with current therapies."

The committee's vote was made after Roche presented results from five Phase III clinical trials. The clinical development program was designed to evaluate the effects of Actemra on signs and symptoms of RA, physical function, progression of structural damage, and health-related quality of life. Of these five studies, three trials were conducted in patients with inadequate response to disease modifying anti-rheumatic drugs (DMARDs), one trial was conducted in patients who failed anti-tumor necrosis factor (TNF) therapy, and one monotherapy study comparing Actemra to methotrexate, a current standard of care, was also conducted. Results of these studies demonstrated that treatment with Actemra -- alone or in combination with methotrexate or other DMARDs -- significantly reduced RA signs and symptoms, regardless of previous therapy or disease severity, compared with current DMARDs.

About Actemra (tocilizumab)

Actemra is the first humanized interleukin-6 (IL-6) receptor-inhibiting monoclonal antibody. Studies suggest that reducing the activity of IL-6, one of several key cytokines involved in the inflammatory process, may reduce inflammation of the joints and relieve certain systemic effects of RA. The extensive clinical development program conducted by Roche includes five clinical studies and has enrolled more than 4,000 patients in 41 countries, including the United States. Five Phase III studies are completed and have reported meeting their primary endpoints. The LITHE trial evaluating Actemra in RA is an ongoing two-year study and is expected to report complete data evaluating the effects of Actemra on the inhibition of structural joint damage in 2009. Actemra is awaiting approval in the United States and Europe.

Actemra is part of a co-development agreement with Chugai, a Japanese company. In June 2005, Actemra was launched by Chugai in Japan as a therapy for Castleman's disease; in April 2008, additional indications for rheumatoid arthritis, juvenile idiopathic arthritis and systemic-onset juvenile idiopathic arthritis were also approved in Japan.

The serious adverse events reported in Actemra clinical trials include serious infections, diverticular perforations, and hypersensitivity reactions including anaphylaxis. The most common adverse events reported in clinical trials were upper respiratory tract infection, nasopharyngitis, headache and hypertension. Increases in liver function tests (ALT and AST) were seen in some patients; these increases were generally mild and reversible, with no hepatic injuries or any observed impact on liver function. Laboratory changes, including increases in lipids (total cholesterol, LDL, HDL, triglycerides) and decreases in neutrophils and platelets, were seen in some patients without association with clinical outcomes.

About IL-6

IL-6 is a common protein found in all joints in the body and is a natural substance that can raise inflammation. Everyone has IL-6 in their body, but people with RA may have too much. If approved, Actemra will be the first and only medication to specifically target IL-6 in patients with RA.

About Rheumatoid Arthritis

Rheumatoid arthritis is a progressive, systemic autoimmune disease characterized by inflammation of the membrane lining in the joints. This inflammation causes a loss of joint shape and function, resulting in pain, stiffness and swelling, ultimately leading to irreversible joint destruction and disability. Characteristics of RA include redness, swelling, pain and movement limitation around joints of the hands, feet, elbows, knees and neck that leads to loss of function. In addition, the systemic symptoms of RA include fatigue, decreased hemoglobin, osteoporosis and may contribute to shortening life expectancy by affecting major organ systems. After 10 years, less than 50 percent of patients can continue to work or function normally on a daily basis. RA affects more than 21 million people worldwide with approximately 1.3 million adults affected in the United States.
