Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.
The safety data described below are based on one, randomized, double-blind, controlled Phase 3 trial in patients with RA receiving SIMPONI ARIA by intravenous infusion (Trial 1). The protocol included provisions for patients taking placebo to receive treatment with SIMPONI ARIA at Week 16 or Week 24 either by patient response (based on uncontrolled disease activity) or by design, so that adverse events cannot always be unambiguously attributed to a given treatment. Comparisons between placebo and SIMPONI ARIA were based on the first 24 weeks of exposure.
Trial 1 included 197 control-treated patients and 463 SIMPONI ARIA-treated patients (which includes control-treated patients who switched to SIMPONI ARIA at Week 16). The proportion of patients who discontinued treatment due to adverse reactions in the controlled phase of Trial 1 through Week 24 was 3.5% for SIMPONI ARIA-treated patients and 0.5% for placebo-treated patients. Upper respiratory tract infection was the most common adverse reaction reported in the trial through Week 24 occurring in 6.5% of SIMPONI ARIA-treated patients as compared with 7.6% of control-treated patients, respectively.
Serious infections observed in SIMPONI ARIA-treated patients included sepsis, pneumonia, cellulitis, abscess, opportunistic infections, tuberculosis (TB), and invasive fungal infections. Cases of TB included pulmonary and extrapulmonary TB. The majority of the TB cases occurred in countries with a high incidence rate of TB [see WARNINGS AND PRECAUTIONS].
In the controlled phase of Trial 1 through Week 24, infections were observed in 27% of SIMPONI ARIA-treated patients compared with 24% of control-treated patients, and serious infections were observed in 0.9% of SIMPONI ARIA-treated patients and 0.0% of control-treated patients. Through Week 24, the incidence of serious infections per 100 patient-years of follow-up was 2.2 (95% CI 0.61, 5.71) for the SIMPONI ARIA group, and 0 (0.00, 3.79) for the placebo group. In the controlled and uncontrolled portions of Trial 1, 958 total patient-years of follow-up with a median follow-up of approximately 92 weeks, the incidence per 100 patient-years of all serious infections was 4.07 (CI: 2.90, 5.57) in patients receiving SIMPONI ARIA [see WARNINGS AND PRECAUTIONS]. In the controlled and uncontrolled portions of Trial 1, in SIMPONI ARIA treated patients, the incidence of active TB per 100 patient-years was 0.31 (95% CI: 0.06; 0.92) and the incidence of other opportunistic infections per 100 patient-years was 0.42 (95% CI: 0.11, 1.07).
One case of malignancy other than lymphoma and NMSC with SIMPONI ARIA was reported through Week 24 during the controlled phase of Trial 1. In the controlled and uncontrolled portions through approximately 92 weeks, the incidence of malignancies per 100 patient years, other than lymphoma and NMSC, in SIMPONI ARIA-treated patients was 0.31 (CI: 0.06, 0.92) and the incidence of NMSC was 0.1 (95% CI: 0.00, 0.58).
Liver Enzyme Elevations
In the controlled phase of Trial 1, through Week 24, ALT elevations ≥ 5 x ULN occurred in 0.6% of SIMPONI ARIA-treated patients and 0% of control-treated patients and ALT elevations ≥ 3 x ULN occurred in 2.4% of SIMPONI ARIA-treated patients and 2.5% of control-treated patients.
Since many of the patients in the Phase 3 trial were also taking medications that cause liver enzyme elevations (e.g., nonsteroidal anti-inflammatory drugs [NSAIDs], methotrexate [MTX], or isoniazid prophylaxis), the relationship between SIMPONI ARIA and liver enzyme elevation is not clear.
Autoimmune Disorders and Autoantibodies
The use of TNF-blockers, of which SIMPONI ARIA is a member, has been associated with the formation of autoantibodies and, rarely, with the development of a lupus-like syndrome.
At Week 20 in Trial 1, 17% of SIMPONI ARIA-treated patients and 13% of control patients were newly ANA-positive (at titers of 1:160 or greater). Of these patients, one SIMPONI ARIA-treated patient and no control-treated patients had newly positive anti-dsDNA antibodies.
In the controlled phase of Trial 1 through Week 24, 1.1% of SIMPONI ARIA infusions were associated with an infusion reaction compared with 0.2% of infusions in the control group. The most common infusion reaction in SIMPONI ARIA treated patients was rash. No serious infusion reactions were reported.
Antibodies to SIMPONI ARIA were detected in 13 (3%) golimumab-treated patients following IV administration of SIMPONI ARIA in combination with MTX through Week 24 of Trial 1.
All patients who were positive for antibodies to golimumab had neutralizing antibodies based on an in vitro cell-based assay. The small number of patients positive for antibodies to SIMPONI ARIA limits the ability to draw definitive conclusions regarding the relationship between antibodies to golimumab and clinical efficacy or safety measures.
The data above reflect the percentage of patients whose test results were considered positive for antibodies to SIMPONI ARIA in an ELISA assay. The ELISA assay is subject to interference by co-present golimumab and thus the results are an underestimate of the rate of product immunogenicity and are in addition highly dependent on the sensitivity and specificity of the assay. Additionally, the observed incidence of antibody positivity in an assay may be influenced by several factors including sample handling, timing of sample collection, concomitant medications, and underlying disease. For these reasons, comparison of the incidence of antibodies to SIMPONI ARIA with the incidence of antibodies to other products may be misleading.
Other Adverse Reactions
Table 1 summarizes the adverse drug reactions that occurred at a rate of at least 1% in the SIMPONI ARIA + MTX group with a higher incidence than in the placebo + MTX group during the controlled period of Trial 1 through Week 24.

Other and less common clinical trial adverse drug reactions
Adverse drug reactions that do not appear in Table 1 or that occurred < 1% in SIMPONI ARIA -treated patients during Trial 1 through Week 24 that do not appear in the Warnings and Precautions section included the following events listed by system organ class:
Nervous system disorders: Dizziness, paresthesia
Gastrointestinal disorders: Constipation
There is no post-marketing experience available for SIMPONI ARIA. The following adverse reactions have been identified during post-approval use of the subcutaneous formulation of golimumab. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to golimumab exposure.
Skin and subcutaneous tissue disorders: Skin exfoliation

SIMPONI ARIA should be used with methotrexate (MTX) [see Clinical Studies]. Following IV administration, concomitant administration of methotrexate decreases the clearance of SIMPONI ARIA by approximately 9% based on population PK analysis. In addition, concomitant administration of methotrexate decreases the SIMPONI ARIA clearance by reducing the development of anti-golimumab antibodies.
Biologic Products for RA
An increased risk of serious infections has been seen in clinical RA studies of other TNF-blockers used in combination with anakinra or abatacept, with no added benefit; therefore, use of SIMPONI ARIA with other biologic products, including abatacept or anakinra is not recommended [see WARNINGS AND PRECAUTIONS]. A higher rate of serious infections has also been observed in RA patients treated with rituximab who received subsequent treatment with a TNF-blocker. The concomitant use of SIMPONI ARIA with biologics approved to treat RA is not recommended because of the possibility of an increased risk of infection.
Infants born to women treated with SIMPONI ARIA during their pregnancy may be at increased risk of infection for up to 6 months. Administration of live vaccines to infants exposed to SIMPONI ARIA in utero is not recommended for 6 months following the mother's last SIMPONI ARIA infusion during pregnancy [see Use In Specific Populations].
Cytochrome P450 Substrates
The formation of CYP450 enzymes may be suppressed by increased levels of cytokines (e.g., TNFα) during chronic inflammation. Therefore, it is expected that for a molecule that antagonizes cytokine activity, such as golimumab, the formation of CYP450 enzymes could be normalized. Upon initiation or discontinuation of SIMPONI ARIA in patients being treated with CYP450 substrates with a narrow therapeutic index, monitoring of the effect (e.g., warfarin) or drug concentration (e.g., cyclosporine or theophylline) is recommended and the individual dose of the drug product may be adjusted as needed.
