PRINCETON, N.J.--(BUSINESS WIRE)--Bristol-Myers Squibb Company (NYSE:BMY) announced today its first release of new data from a Phase IIIb RA trial showing that the T-cell co-stimulation modulator, Orencia ® (abatacept), in combination with methotrexate (MTX) achieved significantly higher rates of DAS-defined (DAS28 CRP <2.6) remission at 12 months than treatment with standard of care agent MTX (60.9% vs. 45.2%, respectively), in biologic and MTX-naïve patients with early active RA. The data are being presented this week at the 2014 annual meeting of the European League Against Rheumatism (EULAR).
In this trial, known as AVERT (Assessing Very Early Rheumatoid arthritis Treatment), a co-primary endpoint assessed maintenance of remission following the withdrawal of all RA drug therapy including Orencia, MTX and steroids. A small but statistically significantly higher number of patients treated with Orencia plus MTX, versus MTX alone, for 12 months maintained remission 6 months after all RA treatment was withdrawn.
Orencia was well tolerated in the study patients. In particular, serious adverse events, serious infection events and discontinuation due to serious adverse events were comparable to patients treated with MTX.
“Remission of both clinical symptoms and radiographic joint damage is an important and achievable goal in the management of rheumatoid arthritis, particularly in the early disease phase,” said Paul Emery, M.D., Arthritis Research UK Professor of Rheumatology and Head of the Academic Division of Musculoskeletal Disease, Leeds Institute of Molecular Medicine, University of Leeds, United Kingdom. “Data from the AVERT trial show that patients taking a combination of Orencia plus methotrexate achieved higher rates of remission than treating them with methotrexate alone. Interestingly, this benefit was maintained in some patients even after all RA treatment had been withdrawn.”
“These data demonstrating higher remission rates and a similar safety profile for Orencia plus methotrexate versus methotrexate alone, in conjunction with insights from the withdrawal phase of the study, support the use of Orencia as a first line biologic therapy for patients with RA,” said Michael Giordano, senior vice president, head of development, Oncology and Immunology, Bristol-Myers Squibb.
Data from the AVERT Trial
AVERT is a Phase IIIb, active-controlled study including 351 adult patients with symptoms of RA for less than two years, positive for anti-CCP antibodies, DAS28 CRP >3.2 and naïve to treatment with methotrexate and biologic therapies for RA. The patients were randomly assigned to 12 months of weekly treatment in one of three groups: Orencia 125 mg subcutaneous plus MTX; Orencia 125 mg subcutaneous alone; or MTX alone. Participants who had a DAS28 CRP <3.2 (indicating low disease activity) after the 12-month treatment phase were able to continue in a withdrawal period up to 12 months, where all RA treatment including Orencia, MTX and steroids were withdrawn. The co-primary endpoints compared the proportion of patients with DAS28 CRP <2.6 (defined as disease remission in the trial) at month 12 and both months 12 and 18 for combination therapy versus MTX alone.
At 12 months, significantly more patients on Orencia combination therapy achieved DAS28-defined remission (60.9%, Orencia plus MTX; 45.2%, MTX alone). Similar results at 12 months were seen with more stringent measures of efficacy including Boolean remission (37.0%, Orencia plus MTX; 22.4%, MTX alone), CDAI remission (42%, Orencia plus MTX; 27.6% MTX alone), and SDAI remission (42%, Orencia plus MTX; 25% MTX alone).
Greater benefits on MRI endpoints were also observed with combination therapy vs. MTX alone, including improvements in synovitis and osteitis, and less progression of joint erosions. At 12 months the adjusted mean change from baseline in total synovitis score was -2.35 for Orencia plus MTX vs. -0.68 for MTX alone; the adjusted mean change from baseline in total osteitis score was -2.58 for Orencia plus MTX vs. -0.68 for MTX alone; and the adjusted mean change from baseline in total erosion score was 0.19 for Orencia plus MTX vs. 1.52 for MTX alone.
A monotherapy arm of the AVERT trial resulted in a similar number of patients treated with Orencia in the absence of MTX achieving DAS-defined remission as compared to MTX-treated patients at 12 months (42.5% versus 45.2%, respectively). While the rates were similar at 12 months, Orencia monotherapy resulted in trends towards higher DAS-defined remission rates than MTX monotherapy at most earlier time points.
After 12 months, following rapid treatment withdrawal of all RA therapy including Orencia, MTX and steroids in patients achieving DAS <3.2, 79.4% of patients went back on therapy because of worsening RA symptoms. However, a small and statistically significantly higher number of patients treated with Orencia combination therapy were able to maintain drug-free remission versus MTX alone up to Month 18 (14.8% versus 7.8%, respectively), 6 months after drug withdrawal. Drug-free remission rates were 12.4% for Orencia monotherapy.
Orencia, as monotherapy or in combination with MTX, in early RA patients had a comparable safety profile to MTX. Over 12 months of treatment, 6.7%, 12.1%, and 7.8% of patients on Orencia plus MTX, Orencia alone, and MTX alone, respectively, experienced a serious adverse event and 1.7%, 4.3% and 2.6% led to discontinuation. Serious infections were observed in 0.8% of patients in the combination arm and 3.4% in the Orencia monotherapy arm. None of the patients in the MTX alone arm experienced a serious infection.
About Rheumatoid Arthritis
Rheumatoid arthritis (RA) is a systemic, chronic, autoimmune disease characterized by inflammation in the lining of joints (or synovium), causing joint damage with chronic pain, stiffness, swelling and fatigue. RA causes limited range of motion and decreased joint function. The condition is more common in women than in men, who account for 75% of patients diagnosed with RA.

Important Safety Information About ORENCIA® (abatacept)
Inform your healthcare provider of the following, before you receive treatment with ORENCIA:
Infections: If you have any kind of infection, even if it is small (such as an open cut or sore), an infection that is in your whole body (such as the flu), an infection that will not go away, or a history of infections that keep coming back. ORENCIA may make your immune system less able to fight infections, so you may be more likely to get infections or any infection you have may get worse.
Tuberculosis: If you have had tuberculosis (TB), a positive skin test for TB, or if you recently have been in close contact with someone who has had TB. If you get any of the symptoms of TB (a dry cough that does not go away, weight loss, fever, night sweats), call your healthcare provider right away. Before you start ORENCIA, your healthcare provider may examine you for TB or perform a skin test.
If you have or have had Viral Hepatitis. Before you use ORENCIA, your healthcare provider may examine you for hepatitis.
If you have a history of Chronic Obstructive Pulmonary (lung) Disease (COPD).
If you are scheduled to have Surgery.
Allergies to the Ingredients of ORENCIA®(abatacept): The ingredients of intravenous (IV) ORENCIA are: abatacept, maltose, monobasic sodium phosphate, and sodium chloride for administration. The ingredients of subcutaneous (SC) ORENCIA are: abatacept, sucrose, poloxamer 188, monobasic sodium phosphate monohydrate, dibasic sodium phosphate anhydrous, and water for injection.
