For every additional 6 months of treatment CV risk reduces further

Berlin, Germany, June 7 2012: Results from a retrospective analysis of contemporary data presented today at EULAR 2012, the Annual Congress of the European League Against Rheumatism, predict, based on estimates from a multivariate regression model, that the cumulative use of anti-tumour necrosis factor drugs (anti-TNFs) for one, two, or three years is associated with reduced risk of cardiovascular events by 24%, 42% and 56% in patients with rheumatoid arthritis (RA) respectively, compared to not using anti-TNF therapies (adjusting for background use of methotrexate or other disease modifying anti-rheumatic drugs [DMARDs]).

The model, based on 109,462 patients demonstrated that each additional six months of treatment with anti-TNFs significantly reduces the risk of cardiovascular events (myocardial infarction [MI], stroke/transient ischemic attack, unstable angina, or heart failure) (Hazard Ratio [HR]=0.87, p=0.005). Breaking this benefit down further, the same model shows that the risk of MI was also significantly reduced (HR=0.80, p=0.013).

Focusing on some subgroups of patients, each additional six months of anti-TNF therapy significantly reduced the risk of cardiovascular events in RA patients aged ?50 years (HR =0.86, p=0.007) as well as in those without prior treatment with methotrexate (HR=0.85, p=0.022).

"RA and heart disease have a common origin and the systemic inflammation involved in RA is thought to also promote cardiovascular disease and even cardiovascular death. Studies have shown that within the first ten years of being diagnosed with RA, the risk of a heart attack almost doubles," said Dr. Michael Nurmohamed, VU University Medical Centre & Jan van Breemen Research Institute, Reade, The Netherlands and lead study author. "As anti-TNFs are now the treatment of choice for patients who are unstable on methotrexate, the decreased cardiovascular risk observed in the study is an added bonus to an already successful class of drugs."

The study using U.S. health plan claims identified 109,462 patients with ?2 rheumatoid arthritis diagnoses and ?1 filled prescription of anti-TNF therapy, methotrexate therapy, or other non-biologic DMARD. Patients were assessed from index fill date to first inpatient cardiovascular event diagnosis or to the end of health plan enrolment or to six months after discontinuation of their index drug, whichever came first. This included a total of 105,920 patient years of follow up, including 48,621 patient years of exposure to anti-TNFs, 35,480 patient years of exposure to methotrexate, and 52,994 patient years of exposure to other non-biologic DMARDs. A total of 1,743 patients (1.6%) had a cardiovascular event after their index prescription.

About EULAR

• The European League Against Rheumatism (EULAR) is the organisation which represents the patient, health professional and scientific societies of rheumatology of all the European nations
• In line with The European Union of Medical Specialists (UEMS), EULAR defines rheumatology as including rheumatic diseases of the connective tissue, locomotor and musculoskeletal systems
• EULAR aims to promote, stimulate and support the research, prevention, treatment and rehabilitation of rheumatic diseases. With 45 scientific member societies, 36 PARE organisations and 10 health professionals associations, EULAR underscores the importance of combating rheumatic diseases not only by medical means, but also through a wider context of care for rheumatic patients and a thorough understanding of their social and other needs
• Diseases of the bone and joints such as rheumatoid arthritis and osteoarthritis cause disability in 4-5% of the adult population and are predicted to rise as people live longer
• EULAR 2012 is set to be the biggest rheumatology event in Europe with over 15,000 scientists, physicians, allied health professionals, and related audiences in attendance from over 115 countries. Over the course of the congress, more than 275 oral and 1400 poster abstract presentations will be featured, with 1,010 invited speaker lectures taking place in 190 sessions
