Results from a Phase 2 rheumatoid arthritis (RA) study assessing the safety and efficacy of golimumab (CNTO 148), a fully-human anti-TNF-alpha therapy, showed that it achieved the primary endpoint of the study. In this dose-ranging trial, more than 60 percent of patients with moderately to severely active RA treated with golimumab and methotrexate (MTX) experienced at least 20 percent improvement in arthritis symptoms at week 16.

Additionally, one-quarter of patients receiving golimumab and MTX achieved remission as evaluated by Disease Activity Score 28 (DAS28). These findings will be presented this week at the American College of Rheumatology 2005 Annual Scientific Meeting.

"When treating a debilitating disease like RA, it is important to have several treatment options, and we are encouraged by the safety and efficacy data we have seen thus far for golimumab," said Jonathan Kay, MD, Director, Clinical Trials, Rheumatology Unit, Massachusetts General Hospital, Associate Clinical Professor of Medicine, Harvard University School of Medicine and lead study investigator.

Golimumab, developed by Centocor, Inc. and Schering-Plough, is a fully-human anti-TNF-alpha IgG1 monoclonal antibody that targets and neutralizes both the soluble and the membrane-bound form of TNF-alpha. Golimumab is currently being investigated for administration by either subcutaneous (SC) injection or intravenous (IV) infusion.

Data from the study showed that significantly more patients in all groups receiving SC injections of golimumab plus MTX achieved ACR 50 response (marked improvement in arthritis symptoms according to the American College of Rheumatology scoring criteria) versus patients receiving placebo plus MTX. Adults with active RA for at least three months' duration despite MTX therapy were randomized to one of five treatment groups: placebo every two weeks or golimumab 50 or 100 mg every two weeks or every four weeks. All patients received stable doses of MTX of greater than or equal to 10 mg/week. After just 16 weeks of treatment, 62 percent of all patients receiving golimumab (combined golimumab treatment groups) experienced at least 20 percent improvement in arthritis symptoms (ACR 20), compared with 37 percent of placebo-treated patients (P = 0.008). Additionally, at week 16, 31 percent of patients in the combined golimumab treatment groups achieved ACR 50, and 12 percent achieved ACR 70, compared with six percent and zero percent, respectively, of patients in the placebo group. All individual golimumab treatment groups achieved higher ACR 20 response rates than placebo. Golimumab 50 mg every four weeks (63 percent) and golimumab 100 mg every two weeks (79 percent) were statistically significantly more effective than placebo (37 percent) in achieving an ACR 20 response (P = 0.031 and P < 0.001, respectively).

Patients in the golimumab plus MTX treatment group also achieved remission, as assessed by DAS 28, which measures tender and swollen joints, inflammation and overall disease activity including measurement of serum C-reactive protein (CRP) levels. After 16 weeks of treatment, 27 percent of patients in the combined group achieved remission as assessed by DAS28 compared with six percent of patients receiving MTX alone (P = 0.007).

Adverse events in the golimumab groups were similar to those in the MTX group. Serious adverse events were reported in eight percent of patients in the combined golimumab group, compared with six percent in the MTX group. No deaths, cases of tuberculosis or other opportunistic infections were reported and serious infections were uncommon. One case each of lung cancer, congestive heart failure, cardiac tamponade, and two cases of pneumonia were reported among patients treated with golimumab.

About Rheumatoid Arthritis

Rheumatoid arthritis (RA) is a chronic, progressive disease and research demonstrates that a critical therapeutic window exists within the first two years of disease onset when the rate of radiographic progression of the disease can be "reset." 1,2,3 Radiographic changes occur within two years of disease onset in 50 percent to 70 percent of RA patients.4 The American College of Rheumatology suggests control of disease progression should start early to limit joint damage in RA.3 RA is associated with substantial disability and economic losses, and one study showed that one-third of patients in the United Kingdom who were employed became work-disabled within two years of disease onset.5 Rheumatologic disorders also account for 25 percent of Social Security disability payments in the United States.6
