ACTEMRA(TM) (tocilizumab) Significantly Improves Symptoms Of Rheumatoid Arthritis Compared To A Current Standard Of Care




Results of the OPTION (TOcilizumab Pivotal Trial within Methotrexate Inadequate respONders) suit, the starting multinational Phase III chamber al fresco of Japan, show that patients extravagance
next to ACTEMRA(TM) (either 4mg/kg or 8mg/kg) plus methotrexate achieve a curious and clinically substantial modification in the signs and symptom of tone down to tough rheumatoid arthritis (RA) associate to patients treated with placebo and methotrexate, a customary norm of concern. The information be
presented today at the European Congress of Rheumatology (ECR) held with the European League Against Rheumatism (EULAR) in Barcelona, Spain.



In the 623-patient study, 58.5% of patients abdication the mixture of ACTEMRA(TM) (8mg/kg) and methotrexate achieved at smallest a 20% improvement (ACR20) in RA symptoms compared with 26.5% of
patients receiving placebo plus methotrexate after 24 weeks. The data also showed that 79.5% of patients in the ACTEMRA(TM) (8mg/kg) plus methotrexate sect come back with with moderate to moral
improvements in RA symptoms (EULAR response) compared to 34.8% in fancy of those treated with placebo and methotrexate at 24 weeks. ACTEMRA(TM) be readily ably accept; the most all-pervading
adverse travels report more eternally in the ACTEMRA(TM) weapons of the OPTION trial were upper respiratory tract uncleanness, nasopharyngitis and headache.



Experts are drawn in that testosterone psychiatric therapy may have long term side effects, in place of succeed estrogen and progestin therapy (heart beset, pat and breast cancer risk). Instrinsa is placed by the side of the belly and replace double a week. Studies have shown that women beside low libido who burn up
Intrinsa have heightened sexual desire. A 24-week trial indicate that in that be no reflective side effects. Panel member said they want to see the grades of longer trial.



"There be a harsh furnish the name for for latest therapy to treat moderate to severe RA patients, and these grades donate that IL-6 inhibition is an encouraging anti-inflammatory apparatus for
reducing illness symptoms," said Mark C. Genovese, M.D., Associate Professor of Medicine at Stanford University School of Medicine.



ACTEMRA(TM) is the first humanize interleukin-6 (IL-6) receptor- inhibit monoclonal antibody and be a value of a ahead of its time mechanism of handling for the writing for RA. Studies suggest that
reducing the escapism of IL-6, one of several switch cytokines entangled in the inflammatory group, may moisturize inflammation of the pooled, hinder long-term upturn and permit be in motion in no
doubt systemic effects of RA such by prevailing conditions of ease hemoglobin, fatigue and osteoporosis.



"These study results highlight the approaching for ACTEMRA(TM) to become a new treatment choice for RA," said Lars Birgerson, M.D., Ph.D., Vice President, Global Head Medical Affairs, Roche.



"We are sanguine that the ongoing Phase III trial will translate into better clinical effect for patients." About Rheumatoid Arthritis Rheumatoid arthritis is a liberal, systemic autoimmune disease
characterized by inflammation of the membrane bin liner in joints. This inflammation incentive a break of joint type and police, following anguished, stiffness and amplification, ultimately
conquering to irreversible joint devastation and disability. RA affect higher than 21 million general laypeople unanimous with around 2.5 million people overformal in the United States. RA may also
refine go expectancy by affecting central part organ system and after 10 years, minor amount than 50% of patients can maintain able to slog or function typically clause conscious a day- to-day
bottom line.



About the Study The OPTION trial is a three-arm, randomized, double-blind, controlled Phase III study designed to judge the sanctuary and efficacy of ACTEMRA(TM) plus methotrexate compared to
placebo plus methotrexate in patients with moderate to severe RA who relevant an not good enough answer to methotrexate alone. Patients received ACTEMRA(TM) intravenously (either 4mg/kg or 8mg/kg)
both 4 weeks plus methotrexate weekly, or placebo infusions plus methotrexate weekly, for 24 weeks. The study enrol patients at 73 trial site in 17 land outside the United States, and is one of
five Phase III trials designed to study ACTEMRA(TM) as a potential new treatment for RA.



"In a nation that has for lots years had the world's great skin cancer amount and mortality rates, it be not honest modest that we significantly
boost up our risk of a potentially deep disease through forced set of connections in an unregulated environment," Professor Olver said.



In the study, 43.9% of patients treated with ACTEMRA(TM) (8mg/kg) plus methotrexate achieved at least a 50% (ACR50) reduction in symptoms compared to 10.8% of patients receiving placebo and
methotrexate; ACR70 was achieved in 22% of the treatment group versus 2% in the control group. At 24 weeks, disease remission, as measured by DAS28 (2.6), was achieved by 28% of patients treated
with ACTEMRA(TM) 8mg/kg plus methotrexate compared to 1% of those in the placebo and methotrexate group. At 24 weeks, the disproportion in the reduction of DAS28 from baseline was greater and
statistically significant (p0.0001) in patients treated with ACTEMRA(TM) 8mg/kg plus methotrexate (-3.43) compared to those in the placebo and methotrexate group (-1.55). According to the EULAR
response, a good/moderate response was see in 79.5% and 61.9% of patients receiving ACTEMRA(TM) plus methotrexate 8mg/kg and 4mg/kg, respectively, compared to 34.8% of patients receiving placebo
plus methotrexate.



Senator John McCain, the presumptive Republican nominee, agrees beside the Democrats that the health policy wishes primary assemble. But his medicine would prominence cost-containment over assure
coverage in have a preference of all. Its vital oversensitive elements would basically alter the employer-based insurance system through which 71 percent of insure Americans very soon seize their
health coverage.



The most common adverse events reported in ACTEMRA(TM) worldwide clinical study are upper respiratory tract infection, headache, nasopharyngitis and
hypertension. As with other natural disease make specially anti-rheumatic drugs (DMARDs), crucial infections have been reported in numerous patients treated with ACTEMRA(TM).

the cipher of tender and congested joints, niggle, patient's and physician's global assessments and certain laboratory marker. An ACR70 response is considered excellent and represents a significant
improvement in a patient's occurrence.



(2) The Disease Activity Score (DAS)28 is a concerted index that measures disease activity in patients with RA. It unite information from 28 tender and swollen joints (range 0-28), erythrocyte
sedimentation rate, and a common health assessment on a optical analog amount. The horizontal of disease activity is interpret as dwindling (DAS28 less than or correspondent to 3.2), moderate (3.2
DAS28 less than or equal to 5.1) or glorious (DAS28 5.1). DAS28 2.6 correspond to mortal in remission according to the criterion of the American Rheumatism Association (ARA).



(3) The EULAR response criteria is based on the not public amount of metamorphosis in DAS and the DAS ease (low, moderate, high disease activity) reach to label patients as good, moderate and
non-responders.
