Golimumab in patients with active rheumatoid arthritis after treatment with tumour necrosis factor α inhibitors (GO-AFTER study): a multicentre, randomised, double-blind, placebo-controlled, phase III trial

BACKGROUND Tumour necrosis factor alpha (TNFalpha) inhibitors are frequently used to treat rheumatoid arthritis, but whether use of a different TNFalpha inhibitor can improve patient response is unknown. We assess the efficacy and safety of the TNFalpha inhibitor golimumab in patients with active rheumatoid arthritis who had previously received one or more TNFalpha inhibitors. METHODS 461 patients with active rheumatoid arthritis from 82 sites in 10 countries were randomly allocated by interactive voice response system, stratified by study site and methotrexate use, to receive subcutaneous injections of placebo (n=155), 50 mg golimumab (n=153), or 100 mg golimumab (n=153) every 4 weeks between Feb 21, 2006, and Sept 26, 2007. Allocation was double-blind. Eligible patients had been treated with at least one dose of a TNFalpha inhibitor previously. Patients continued stable doses of methotrexate, sulfasalazine, hydroxychloroquine, oral corticosteroids, and non-steroidal anti-inflammatory drugs. The primary endpoint was achievement at week 14 of 20% or higher improvement in American College of Rheumatology criteria for assessment of rheumatoid arthritis (ACR20). At week 16, patients who had less than 20% improvement in tender and swollen joint counts were given rescue therapy and changed treatment from placebo to 50 mg golimumab, or from 50 mg to 100 mg golimumab. Drug efficacy was assessed by intention to treat and safety was assessed according to the study drug given. This study is registered with ClinicalTrials.gov, number NCT00299546. FINDINGS Patients had discontinued previous TNFalpha inhibitors because of lack of effectiveness (269 [58%] patients) or reasons unrelated to effectiveness (246 [53%] patients), such as intolerance and accessibility issues. Patients had active disease, which was indicated by a median of 14.0 (IQR 9.0-22.0) swollen and 26.0 (16.0-41.0) tender joints for the whole group. 28 (18%) patients on placebo, 54 (35%) patients on 50 mg golimumab (odds ratio 2.5 [95% CI 1.5-4.2], p=0.0006), and 58 (38%) patients on 100 mg golimumab (2.8 [1.6-4.7], p=0.0001) achieved ACR20 at week 14. Two patients were never treated, and 57 patients did not complete the study because of adverse events, unsatisfactory treatment effect, loss to follow-up, death, or other reasons. 155 patients on placebo, 153 on 50 mg golimumab, and 153 on 100 mg golimumab were assessed for drug efficacy. For weeks 1-16, serious adverse events were recorded in 11 (7%) patients on placebo, 8 (5%) on 50 mg golimumab, and 4 (3%) on 100 mg golimumab. For weeks 1-24, after some patients were given rescue therapy, serious adverse events were recorded in 15 (10%) patients on placebo, 14 (5%) on 50 mg golimumab, and 8 (4%) on 100 mg golimumab. INTERPRETATION Golimumab reduced the signs and symptoms of rheumatoid arthritis in patients with active disease who had previously received one or more TNFalpha inhibitors.

The effect of two golimumab doses on radiographic progression in ankylosing spondylitis: results through 4 years of the GO-RAISE trial

Objective To evaluate radiographic progression in patients with ankylosing spondylitis (AS) receiving two different doses of the tumour necrosis factor antagonist golimumab. Methods 356 patients with AS were randomly assigned to placebo, or golimumab 50 mg or 100 mg every 4 weeks (wks). At wk16, patients with inadequate response early escaped with blinded dose adjustments (placebo→golimumab 50 mg, 50 mg→100 mg). At wk24, patients still receiving placebo crossed over to golimumab 50 mg. Lateral view radiographs of the cervical/lumbar spine were obtained at wk0, wk104 and wk208, and scored (two blinded readers, modified Stoke AS Spine Score (mSASSS)). Observed data were used for wk104 analyses; missing wk208 scores were linearly extrapolated. Results Wk104 changes from baseline in mSASSS averaged 1.6±4.6 for placebo crossover, 0.9±2.7 for 50 mg and 0.9±3.9 for 100 mg. By wk208, following golimumab therapy for 3.5–4 years, mean changes in mSASSS were 2.1±5.2 for placebo crossover, 1.3±4.1 for 50 mg and 2.0±5.6 for 100 mg. Less than a third of patients (placebo crossover, 19/66 (28.8%); 50 mg, 29/111 (26.1%); 100 mg, 35/122 (28.7%)) had a definitive change from baseline mSASSS (>2). Less radiographic progression was observed through wk208 in patients without baseline syndesmophytes (0.2 vs 2.8 in patients with ≥1 syndesmophyte; p<0.0001) and with baseline C-reactive protein (CRP) levels ≤1.5 mg/dl (0.9 vs 2.9 with CRP >1.5 mg/dl; p=0.0004). Conclusions No difference in mSASSS change was observed between golimumab 50 mg and 100 mg. The radiographic progression rate remained stable at years 2 and 4, suggesting no acceleration of new bone formation over time. Golimumab-treated AS patients with no syndesmophytes and less systemic inflammation at baseline had considerably less radiographic progression.

Clinical efficacy, radiographic and safety findings through 5 years of subcutaneous golimumab treatment in patients with active psoriatic arthritis: results from a long-term extension of a randomised, placebo-controlled trial (the GO-REVEAL study)

Objectives Assess golimumabs long-term efficacy/safety in psoriatic arthritis (PsA). Methods Adults with active PsA (≥3 swollen and tender joints, active psoriasis) were randomly assigned to subcutaneous placebo, golimumab 50 mg, or golimumab 100 mg every 4 weeks (q4wks) through wk20. All patients received golimumab 50 mg or 100 mg q4wks from wk24 forward. Methotrexate was allowed and taken by approximately half the patients. Findings through 5 years are reported herein. Efficacy assessments included ≥20% improvement in American College of Rheumatology (ACR20) response, C-reactive-protein-based, 28-joint-count Disease Activity Score (DAS28-CRP) response, ≥75% improvement in Psoriasis Area and Severity Index (PASI75) scores, and PsA-modified Sharp/van der Heijde scores (SHSs). Results 126/405 (31%) randomised patients discontinued treatment through wk252. Golimumab was effective in maintaining clinical improvement through year-5 (ACR20: 62.8–69.9%, DAS28-CRP: 75.2-84.9% for randomised patients; PASI75: 60.8–72.2% among randomised patients with ≥3% body surface area involvement) and inhibiting radiographic progression (mean changes in PsA-modified SHS: 0.1–0.3) among patients with radiographic data. While concomitant methotrexate did not affect ACR20/PASI75, it appeared to reduce radiographic progression. No new safety signals were identified. Antibodies-to-golimumab occurred in 1.8%/10.0% of patients with/without methotrexate). Conclusions Long-term golimumab safety/efficacy in PsA was demonstrated through 5 years. Trial registration number NCT00265096.

Golimumab in patients with active rheumatoid arthritis who have previous experience with tumour necrosis factor inhibitors: results of a long-term extension of the randomised, double-blind, placebo-controlled GO-AFTER study through week 160

Objective The aim of this study was to assess long-term golimumab therapy in patients with rheumatoid arthritis (RA) who discontinued previous tumour necrosis factor alpha (TNFα) inhibitor(s) for any reason. Methods Results through week 24 of this multicentre, randomised, double-blind, placebo-controlled study of active RA (≥4 tender, ≥4 swollen joints) were previously reported. Patients received placebo (Group 1), 50 mg golimumab (Group 2) or 100 mg golimumab (Group 3) subcutaneous injections every 4 weeks. Patients from Groups 1 and 2 with <20% improvement in tender/swollen joints at week 16 early escaped to golimumab 50 mg and 100 mg, respectively. At week 24, Group 1 patients crossed over to golimumab 50 mg, Group 2 continued golimumab 50/100 mg per escape status and Group 3 maintained dosing. Data through week 160 are reported. Results 459 of the 461 randomised patients were treated; 236/459 (51%) continued treatment through week 160. From week 24 to week 100, ACR20 (≥20% improvement in American College of Rheumatology criteria) response and ≥0.25 unit HAQ (Health Assessment Questionnaire) improvement were sustained in 70–73% and 75–81% of responding patients, respectively. Overall at week 160, 63%, 67% and 57% of patients achieved ACR20 response and 59%, 65% and 64% had HAQ improvement ≥0.25 unit in Groups 1, 2 and 3, respectively. Adjusted for follow-up duration, adverse event incidences (95% CI) per 100 patient-years among patients treated with golimumab 50 mg and 100 mg were 4.70 (2.63 to 7.75) and 8.07 (6.02 to 10.58) for serious infection, 0.95 (0.20 to 2.77) and 2.04 (1.09 to 3.49) for malignancy and 0.00 (0.00 to 0.94) and 0.62 (0.17 to 1.59) for death, respectively. Conclusion In patients with active RA who discontinued previous TNF-antagonist treatment, golimumab 50 and 100 mg injections every 4 weeks yielded sustained improvements in signs/symptoms and physical function in ∼57–67% of patients who continued treatment. Golimumab safety was consistent with other anti-TNF agents, although definitive conclusions regarding long-term safety require further monitoring.

Insights into the efficacy of golimumab plus methotrexate in patients with active rheumatoid arthritis who discontinued prior anti-tumour necrosis factor therapy: post-hoc analyses from the GO-AFTER study

Objective Evaluate golimumab in patients with active rheumatoid arthritis (RA) and previous tumour necrosis factor-α (TNF) inhibitor use. Methods Patients (n=461) previously receiving ≥1 TNF inhibitor were randomised to subcutaneous injections of placebo, golimumab 50 mg or golimumab 100 mg q4 weeks. Primary endpoint (≥20% improvement in American College of Rheumatology (ACR20) criteria at week 14) findings have been reported for all patients in the trial. Reported herein are further assessments of efficacy/safety among patients receiving golimumab+methotrexate (MTX). Results Among efficacy-evaluable patients who received MTX at baseline, more receiving golimumab+MTX (n=201) than placebo+MTX (n=103) achieved ACR20 (40.8% vs 14.6%), ACR50 (20.9% vs 3.9%), and ACR70 (11.4% vs 2.9%) responses at week 24. Among the 137 patients who had received only one prior TNF inhibitor (adalimumab, n=33; etanercept, n=47; and infliximab, n=57), week 24 ACR20 rates were 30.3%, 46.8% and 50.9%, respectively, and thus lowest among those who previously used adalimumab. ACR20 response rates were 44.5% (61/137), 36.2% (17/47) and 23.5% (4/17) among patients who had received one, two or three TNF inhibitors, respectively. Adverse event (AE) rates were comparable across type/number of prior anti-TNF agents, but appeared somewhat higher among patients who discontinued previous TNF inhibitor(s) due to intolerance (37/49, 75.5%) versus lack of efficacy (LOE, 113/191, 59.2%). Conclusions Patients with active RA previously treated with ≥1 TNF inhibitor had clinically relevant improvement with golimumab+MTX, which appeared somewhat enhanced among those who received only etanercept or infliximab as their prior TNF inhibitor. Golimumab+MTX safety appeared similar across patients, regardless of TNF inhibitor(s) previously used, with fewer AEs occurring among patients who discontinued prior therapy for LOE.

Five-year Safety Data from 5 Clinical Trials of Subcutaneous Golimumab in Patients with Rheumatoid Arthritis, Psoriatic Arthritis, and Ankylosing Spondylitis.

Objective. Assess 5-year golimumab (GOL) safety in rheumatoid arthritis (RA), psoriatic arthritis (PsA), and ankylosing spondylitis (AS). Methods. Subcutaneous (SC) GOL (50 mg or 100 mg every 4 weeks) was evaluated in phase 3 trials of patients with active RA, PsA, and AS. Safety data through Year 5 were pooled across 3 RA trials [1 each evaluating methotrexate (MTX)-naive, MTX-experienced, and antitumor necrosis factor (TNF)-experienced patients], 1 PsA trial, and 1 AS trial. Data summarized was derived from both placebo-controlled (through weeks 24–52) and uncontrolled study periods. For adverse events (AE) of special interest [serious infections (SI), opportunistic infections (OI), deaths, malignancies, demyelination, tuberculosis (TB)], incidence per 100 patient-years (pt-yrs) was determined. Results. Across all trials, 639 patients received placebo and 2228 received SC GOL 50 mg only (n = 671), 50 mg and 100 mg (n = 765), or 100 mg only (n = 792). Safety followup extended for averages of 28.5 and 203.2 weeks for placebo and GOL, respectively. Respective placebo and GOL AE incidence/100 pt-yrs (95% CI) through Year 5 were 4.86 (2.83–7.78) and 3.29 (2.92–3.69) for SI, 0.00 (0.00–0.86) and 0.23 (0.14–0.35) for TB, 0.00 (0.00–0.86) and 0.22 (0.13–0.34) for OI, 0.00 (0.00–0.86) and 0.10 (0.05–0.20) for lymphoma, 0.00 (0.00–0.86) and 0.08 (0.03–0.17) for demyelination, and 0.29 (0.01–1.59) and 0.41 (0.29–0.57) for death. TB, OI, lymphoma, and demyelination incidence appeared to be higher among patients receiving GOL 100 mg only. Conclusion. SC GOL safety through Year 5 remained consistent with previously reported Year 3 findings and with other TNF antagonists. Numerically higher incidences of TB, OI, lymphoma, and demyelination were observed with 100 mg versus 50 mg.

THU0352 Long-Term Safety and Efficacy of Golimumab in the Treatment of Ankylosing Spondylitis: Results Through 5 Years of the Go-Raise Trial

Background Golimumab(GLM) has demonstrated significant and sustained clinical efficacy and an acceptable safety profile through 2yrs of the phase 3, randomized, PBO-controlled, GO-RAISE study in pts with ankylosing spondylitis (AS). Objectives To evaluate GLM safety/efficacy in AS pts receiving GLM50mg and/or 100mg through 5yrs. Methods 356pts with AS were randomized to SC PBO, GLM50mg, or GLM100mg q4w. At wk16, pts with inadequate response early escaped (EE) with blinded dose adjustments (PBO→GLM50mg, GLM50mg→ 100mg). At wk24, pts still receiving PBO crossed over to GLM50mg. Pts continued double-blind treatment through wk100. The long-term extension started with the wk104 GLM injection. Pts received GLM q4w for ~5yrs (final injection at wk252). After unblinding at wk104 and at the investigator’s discretion, pts receiving GLM50mg could increase their dose to 100mg; pts receiving GLM100mg could decrease dose to 50mg; concomitant DMARD, corticosteroid, and NSAID therapy could be adjusted. Results Among 356 randomized pts, 254 pts continued treatment through wk252; 242 completed the safety follow-up through wk268. 101 pts withdrew (33 [9.3%] due to AEs, 35 [9.8%] lack of efficacy, 11 [3.1%] lost to follow-up, 22 [6.2%] for other reasons); 1pt was untreated. Reductions in AS-related signs/symptoms and improvements in physical function and range of motion observed at wk14 (primary endpoint visit; previously reported) were maintained through 5yrs (Table). Serious AEs were reported for 17.1% of GLM50mg, 24.7% of GLM100mg, and 22.0% of all GLM-treated pts. One pt died (GLM50mg, B cell lymphoma after 3yrs in the study, followed by pancreatic cancer). Conclusions In pts with active AS, SC GLM50 and 100mg q4w improved AS signs/symptoms, physical function, and range of motion and demonstrated an acceptable safety profile that was consistent with previously reported results for GLM through wk160 and with other anti-TNF biologics. There were no differences between the two GLM dosages. Disclosure of Interest A. Deodhar Grant/research support from: Janssen R&D, LLC, J. Braun Grant/research support from: Janssen R&D, LLC, R.
