Efficacy and safety of golimumab as add-on therapy to disease-modifying antirheumatic drugs: results of the GO-MORE study.

OBJECTIVES: To evaluate the efficacy and safety of subcutaneous golimumab as add-on therapy in patients with active rheumatoid arthritis (RA) despite disease-modifying antirheumatic drug (DMARD) treatment. To evaluate an intravenous plus subcutaneous (IV+SC) golimumab strategy in patients who had not attained remission. METHODS: GO-MORE was an open-label, multinational, prospective study in patients with active RA in typical clinical practice settings. In part 1, patients received add-on monthly 50-mg subcutaneous golimumab for 6 months. The percentage of patients with good/moderate European League Against Rheumatism (EULAR) 28-joint disease activity score (DAS28)-erythrocyte sedimentation rate (ESR) response was compared in patient subgroups with various concurrent or previous DMARD treatments. In part 2, patients with EULAR responses but not remission were randomly assigned to receive IV+SC or subcutaneous golimumab to month 12; DAS28-ESR remission was measured. RESULTS: 3366 patients were enrolled. At baseline of part 1, 3280 efficacy-evaluable patients had mean disease duration of 7.6 years and mean DAS28-ESR of 5.97 (SD=1.095). At month 6, 82.1% achieved good/moderate EULAR responses and 23.9% attained remission. When EULAR responses were analysed by the number of previously failed DMARD or the concomitant methotrexate dose, DMARD type, or corticosteroid use, no statistically significant differences were observed. Part 2 patients (N=490) who received IV+SC or subcutaneous golimumab achieved similar remission rates (∼25%). Adverse events were consistent with previous reports of golimumab and other tumour necrosis antagonists in this population. CONCLUSIONS: Add-on monthly subcutaneous golimumab resulted in good/moderate EULAR response in most patients; 25% achieved remission after 6 more months of golimumab, but an IV+SC regimen provided no additional efficacy over the subcutaneous regimen.

Efficacy and safety of golimumab in Indian patients with rheumatoid arthritis: Subgroup data from GO-MORE study.

AIM: To conduct a subgroup analysis of GO-MORE trial Part 1, comparing efficacy and safety of add-on subcutaneous golimumab therapy in rheumatoid arthritis (RA) patients enrolled from and outside India. METHODS: GO-MORE was an open-label, multicenter, prospective trial of add-on golimumab in biologic-naïve RA patients, having active disease despite being on conventional DMARD regimen(s). Part 1 of the study was chosen as the focus of this subgroup analysis because a substantial number of Indian patients (106) were enrolled compared to no Indian patients in Part 2. The primary efficacy outcome was proportion of patients achieving good to moderate DAS28-ESR (Disease Activity Score of 28 joints calculated using erythrocyte sedimentation rate) European League Against Rheumatism (EULAR) response at month 6. RESULTS: Efficacy evaluable population comprised of 105 and 3175 patients from India and outside India, respectively. Safety analysis included 106 patients enrolled from India and 3251 from outside India. A higher proportion of Indian patients had a high disease activity as measured by DAS28 ESR than outside India patients. At month 6, the proportion of Indian and non-Indian patients achieving DAS28-ESR, DAS28 - C-reactive protein, simplified disease activity index (SDAI) remission, and EuroQoL Quality-of-Life Questionnaire (EQ-5D) scores were comparable. Incidence of all adverse events was lower in Indian patients. There were no deaths, cases of tuberculosis or malignancy reported in the patients from India at month 6. CONCLUSIONS: The efficacy and safety results with add-on golimumab were consistent between RA patients from India and outside India, despite high baseline disease activity in the Indian patients.

Long-Term (1-Year) Safety and Efficacy of a Single 6-mL Injection of Hylan G-F 20 in Indian Patients with Symptomatic Knee Osteoarthritis.

INTRODUCTION: The prevalence of symptomatic knee osteoarthritis (OA) among Asians ≥65 years is estimated to double by 2040. This study was designed to evaluate the safety and efficacy of a single, 6-mL intra-articular injection of hylan G-F 20 in Indian patients with knee OA at 26 weeks through to 52 weeks. METHODS: This study was an open-label, multicentre, phase 4 clinical trial. Enrolled patients (N=394) were ≥30 years old with Kellgren-Lawrence grade 1-3 OA; all patients received hylan G-F 20. WOMAC, SF-12, PTGA, and COGA scores, and OA medication use were evaluated at weeks 1, 4, 12, 26, 39, and 52 (initial treatment phase). At 26, 39, or 52 weeks, eligible patients could participate in a repeat treatment phase. McNemar-Bowkers, paired t-tests and ANOVA analyses were performed (alpha=0.05). RESULTS: At 26 weeks, statistically significant changes from baseline were observed in all efficacy parameters, including the primary efficacy endpoint of WOMAC A1 (p<0.0001). Improvements continued for 52 weeks. No significant changes occurred in concomitant medication use. Eleven patients (2.8%) were re-injected at week 26 or 52. After repeat injection, statistically significant decreases were observed in WOMAC A1, WOMAC C and PTGA scores (p≤0.028). Twenty-three (5.8%) patients reported 26 local target knee AEs. CONCLUSION: Among Indian patients within this study, a 6-mL hylan G-F 20 injection was well tolerated and effective in treating symptomatic knee OA with significant long-term (1 year) improvement of outcomes. When needed, repeat treatment was safe and efficacious for 4 weeks. TRIAL REGISTRATION: Clinical Trial Registry of India (CTRI/2010/091/000052) www.ctri.nic.in/Clinicaltrials/login.php.

Association of single nucleotide polymorphisms (SNPs) of PADI4 gene with rheumatoid arthritis (RA) in Indian population.

Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune disease affecting ~ 1% of the population worldwide. The genome wide association studies on RA patients revealed linkage with 1p36 locus containing peptidyl arginine deiminase 4 (PADI4) genes. Case-control association studies and mRNA stability assays reported the association of PADI4 gene with RA in Korean and Japanese populations. However, such association was not found in Spanish population. Differences in the association of PADI4 with RA in different populations prompted the present study in Indian population. Anti-CCP antibodies, RF antibody, disease activity scores at 28 joints (DAS28) and mutations in three exons of PADI4 were investigated in RA patients and control group. Among the patients anti-CCP antibody levels were found to be associated with high DAS28 values (r = 0.4526, P < 0.0001). Polymorphism in exon-4 (padi4_104, [rs1748033]) of PADI4 showed significant association of 'C' allele with RA in the study population (P = 0.0008). Polymorphism in exon-3 (padi4_92, [rs874881]) also exhibited moderate association with the disease (P = 0.075). However, no association of the disease was found with the SNPs padi4_89 [rs11203366] and padi4_90 [rs11203367] in exon-2 of PADI4.
