New Simponi Data Show Inhibition of Joint Damage in Patients With Rheumatoid Arthritis and Psoriatic Arthritis
Results from Radiographic Analyses Show Efficacy of SIMPONI in Inhibiting Joint Destruction in Two Rheumatic Conditions
PHILADELPHIA, October 19, 2009 /PRNewswire/ -- Phase 3 data reported for the first time show that once every four week subcutaneous injections of SIMPONI(TM) (golimumab) resulted in significantly greater inhibition of structural damage compared with placebo plus methotrexate in patients with active rheumatoid arthritis (RA) and active psoriatic arthritis (PsA). Radiographic analyses showed that treatment with SIMPONI resulted in a statistically significant reduction in change from baseline in structural damage as measured using the van der Heijde-Sharp (vdH-S) scoring method, an X-ray measure of changes in joint destruction, including joint erosion and joint space narrowing. These one-year data were presented at the 2009 American College of Rheumatology Annual Scientific Meeting.
"These findings show that treatment with golimumab and methotrexate inhibited the progression of joint damage in patients with active rheumatoid arthritis and psoriatic arthritis," said Dr. Paul Emery, head of the Academic Unit of Musculoskeletal Medicine at the University of Leeds and lead study investigator. "These data reveal important new insights into the efficacy of golimumab and its effect in altering the potential destructive nature of RA and PsA."
At week 52 of the limumab efore mploying methotrexate as the irst-line ption in the treatment of heumatoid arthritis of arly onset (GO-BEFORE) trial, patients with RA receiving SIMPONI plus methotrexate had significantly less progression of structural damage compared with patients receiving placebo plus methotrexate, as measured using the vdH-S score. With this method, higher scores indicate greater structural damage while lower scores indicate less structural damage. The mean change (+/- standard deviation) from baseline in patients treated with SIMPONI 50 mg plus methotrexate was a 0.74 (+/- 5.23) score compared with an increase of 1.37 (+/- 4.56) score in the group receiving placebo plus methotrexate (<0.015). The reduction in progression of vdH-S scores seen with the 50 mg and 100 mg doses was comparable.
In a second study, the limumab subjects ith ctive A espite Methotrexate (GO-FORWARD) clinical trial, vdH-S changes from baseline were minimal in all groups studied (including the placebo arm) which prevented any significant effect of SIMPONI to be detected. A lack of progression in the placebo group may have been due to the short placebo-controlled period of the trial and relatively less active patient population than in previously reported RA trials.
In the limumab - A andomized aluation of Safety and fficacy in Subjects with Psoriatic rthritis Using a Human Anti-TNF Monoclonal Antibody (GO-REVEAL) trial, patients with active PsA receiving SIMPONI 50 mg showed significantly less progression of structural damage at week 24 compared with patients receiving placebo plus methotrexate, and the benefit was maintained through 52 weeks. Structural damage was measured using the vdH-S score. The mean change (+/- standard deviation) from baseline in patients receiving SIMPONI was a decrease of 0.16 (+/- 1.31) score at week 24 compared with an increase of 0.27 (+/- 1.26) score in the placebo group (=0.011). At week 24 all placebo patients began receiving SIMPONI 50 mg. At week 52, the mean change from baseline in total vdH-S score was -0.22 (+/- 1.64) in patients initially randomized to SIMPONI 50 mg at baseline while the mean score in the group who crossed over from placebo to SIMPONI at week 24 was 0.22 (+/- 1.38).
"Results from the GO-REVEAL study show that treatment with golimumab inhibited joint destruction in patients with active psoriatic arthritis," said Dr. Arthur Kavanaugh, Professor of Medicine at the University of California San Diego's Division of Rheumatology, Allergy and Immunology and lead study investigator. "These findings are important as they offer new information about the efficacy of golimumab in the treatment of this complex disease."
Joint erosion (when inflammation causes bones to wear away at the joint) and joint space narrowing (when the gap between bones closes), were also measured in the study. In patients reporting no erosion at baseline, 87 percent receiving SIMPONI 50 mg remained erosion free at week 24 compared with 72 percent of patients in the placebo group (=0.003). For patients reporting no joint space narrowing at baseline, 97 percent receiving SIMPONI 50 mg remained free of joint space narrowing at week 24 compared with 88 percent in the placebo group (=0.008).
In April 2009, the U.S. Food and Drug Administration (FDA) and Health Canada approved SIMPONI 50 mg as a once-monthly subcutaneous injection for the treatment of moderately to severely active RA, active PsA and active ankylosing spondylitis. In October 2009, the European Commission approved SIMPONI as a once-monthly, subcutaneous injection for the treatment of moderate to severe, active RA, active and progressive PsA and severe, active ankylosing spondylitis.
GO-BEFORE, a Phase 3, multi-center, double-blind, placebo-controlled study included 637 methotrexate-naive adults with RA and was designed to compare ACR 50 response at week 24 in patients receiving SIMPONI plus methotrexate compared with patients receiving placebo plus methotrexate. Patients with active RA who had more than four tender and swollen joints were included in the multicenter study. Patients were randomly assigned into four groups; Group 1 included patients receiving placebo every four weeks plus methotrexate 20 mg per week; Group 2 included patients receiving golimumab 100 mg every four weeks plus placebo every week; Group 3 and Group 4 included patients receiving SIMPONI 50 mg every four weeks plus methotrexate 20 mg per week and SIMPONI 100 mg every four weeks plus methotrexate 20 mg per week, respectively.
Adverse events were relatively similar across the four patient groups. Through week 24, serious infections were reported in two, one, one and four percent of Groups 1-4, respectively. Serious adverse events were reported in seven percent, three percent, six percent and six percent of patients in Groups 1-4, respectively.
At week 52, four patients had reported malignancies; two patients developed breast cancer, one patient developed Hodgkin's disease and one patient was diagnosed with squamous cell carcinoma of the lip. One patient developed bone tuberculosis at week 52. Two patients had died by week 52; one patient died as a result of post-surgery cardiac arrest and another patient committed suicide.
GO-FORWARD, a Phase 3, multi-center clinical trial included 444 patients with active RA. Adult patients with more than four tender and swollen joints, despite methotrexate therapy, were randomly assigned to receive SIMPONI (50 or 100 mg) plus methotrexate, SIMPONI 100 mg plus placebo or placebo plus methotrexate at weeks 0, 4, 8, 12, 16 and 20. Data were assessed at weeks 14 and 24. The co-primary endpoints were percentage of patients achieving ACR 20 response at week 14 and improvement from baseline in HAQ at week 24.
Through week 24, 68 percent of patients in both the combined SIMPONI plus methotrexate groups and the placebo plus methotrexate group experienced at least one adverse event. Nine percent of patients in the combined SIMPONI plus methotrexate groups experienced a serious adverse event compared with four percent of patients receiving placebo plus methotrexate. Three percent of patients in the combined SIMPONI plus methotrexate groups and one percent in the group receiving placebo plus methotrexate experienced serious infections. Rates of injection site reactions were five percent in the combined SIMPONI plus methotrexate groups and three percent in the group receiving placebo plus methotrexate.
At week 52, 11 percent of patients receiving placebo plus methotrexate reported serious adverse events compared with 17 percent of patients receiving SIMPONI 100 mg plus placebo, 14 percent of patients receiving SIMPONI 50 mg plus methotrexate and 18 percent of patients receiving SIMPONI 100 mg plus methotrexate. Two percent of patients receiving placebo plus methotrexate reported serious infections at week 52 compared with 17 percent of patients receiving SIMPONI 100 mg plus placebo, 14 percent of patients receiving SIMPONI 50 mg plus methotrexate and 18 percent of patients receiving SIMPONI 100 mg plus methotrexate. Four patients participating in the study, two receiving SIMPONI 50 mg plus methotrexate and two receiving SIMPONI 100 mg plus methotrexate, developed malignancies at week 52; two patients developed breast cancer, one patient developed squamous cell and basal cell skin cancer and one patient was diagnosed with basal cell cancer. One patient receiving SIMPONI 100 mg plus placebo died from diarrhea, colitis and sepsis.
The GO-REVEAL trial involved 405 adults with PsA. Patients with at least three swollen and tender joints and active psoriatic skin lesions of at least two cm in diameter were randomly assigned to receive subcutaneous injections of placebo or SIMPONI (50 or 100 mg) every four weeks for two years. The primary endpoint was ACR 20 response at week 14 for combined SIMPONI groups and individual SIMPONI dose groups vs. placebo. At week 16, patients with inadequate arthritis response were switched to SIMPONI 50 mg (patients originally receiving placebo) or SIMPONI 100 mg (patients originally receiving SIMPONI 50 mg). All patients received SIMPONI from week 24. The trial was unblinded to investigators and patients after all patients reached week 52 and the week 52 database was locked. Investigators could choose to dose escalate patients receiving SIMPONI 50 mg to 100 mg based on clinical judgment. The primary endpoint was ACR 20 response at week 14 for combined SIMPONI groups and individual SIMPONI dose groups vs. placebo.
Through week 24, the placebo-controlled portion of the study, two percent of SIMPONI-treated patients experienced serious adverse events compared with six percent of patients in the placebo group. Injection site reactions occurred in five percent of patients receiving SIMPONI and three percent of patients receiving placebo.
At week 52, four malignancies were reported; one colon, one small-cell lung cancer and two cases of basal cell carcinoma. The small-cell lung cancer patient died; another patient died in a climbing accident. Also, one patient developed liver histoplasmosis. Through one year, an analysis comparing malignancies in the study with those in a Surveillance, Epidemiology and End Results (SEER) database suggested no difference between observed and expected cases.
