SIMPONI ARIA - Treatment of Rheumatoid Arthritis

Last Updated: 01/28/2025

Summary

  • Please refer to the US Prescribing Information for SIMPONI ARIA regarding the treatment of adult patients with moderately to severely active rheumatoid arthritis (RA).
  • The efficacy and safety of SIMPONI ARIA for the treatment of patients with active RA despite methotrexate (MTX) therapy were evaluated in 2 phase 3, randomized, double-blind, multicenter, placebo-controlled studies (GO-LIVE and GO-FURTHER).1,2
  • In the GO-LIVE study, a 50% improvement according to the American College of Rheumatology criteria (ACR50) was achieved in 21.4% of patients in the combined SIMPONI ARIA + MTX group at week 14 compared to 13.2% of patients in the placebo + MTX group (primary endpoint; P=0.051). Through week 48, adverse events (AEs) were reported in 81.6% of all SIMPONI ARIA-treated patients and 72.1% of placebo-treated patients. Infections were the most commonly reported AEs (47.9% of SIMPONI ARIA-treated patients vs 41.1% of placebo-treated patients).1
  • In the GO-FURTHER study, a 20% improvement according to the American College of Rheumatology criteria (ACR20) was achieved in 58.5% of patients in the SIMPONI ARIA + MTX group at week 14 compared to 24.9% of patients in the placebo + MTX group (primary endpoint; P<0.001). At week 24, the proportion of patients who developed AEs was similar between the combined SIMPONI ARIA + MTX (52.9%) and the placebo + MTX groups (49.2%).2

CLINICAL DATA

Phase 3 - GO-LIVE

Kremer et al (2010)1,3 assessed the efficacy and safety of SIMPONI ARIA in patients with active RA (≥4 tender and swollen joints, plus at least 2 of the following: 1) C-reactive protein [CRP] ≥1.5 mg/dL or erythrocyte sedimentation rate [ESR] ≥28 mm/hour, 2) morning stiffness ≥30 minutes, 3) bone erosions, or 4) rheumatoid factor [RF] or anti-cyclic citrullinated peptide [CCP] positivity) despite treatment with MTX in a phase 3, randomized, double-blind, multicenter, placebo-controlled study. Further, patients had to be treated with MTX for ≥3 months before screening, including treatment at a stable dose (15-25 mg/week) for ≥4 weeks.

Study Design/Methods

  • A total of 643 adult RA patients were randomized to intravenous (IV) infusions of placebo + MTX (n=129), SIMPONI ARIA 2 mg/kg (n=128), SIMPONI ARIA 4 mg/kg (n=129), SIMPONI ARIA 2 mg/kg + MTX (n=129), or SIMPONI ARIA 4 mg/kg + MTX (n=128) every 12 weeks through week 48. IV infusions were administered at weeks 0, 12, 24, 36, and 48.
  • Patients were permitted to continue stable doses of oral corticosteroids or nonsteroidal anti-inflammatory drugs (NSAIDs). Previous but not current anti-tumor necrosis factor (TNF) therapy was also permitted with appropriate washout (infliximab washout period ≥3 months; etanercept or adalimumab washout period ≥2 months).
  • Patients who had <20% improvement from baseline in both swollen and tender joint counts were eligible to enter early escape at week 16 or have a dose regimen adjustment at week 24 in a blinded manner.
  • Patients who completed the week 48 infusion were eligible to continue in an open-label long-term extension (LTE) with golimumab 50 mg subcutaneously every 4 weeks for an additional 24 weeks (LTE weeks 0-24) beginning 12 weeks after the last IV infusion. Patients were followed for an additional 16 weeks for safety evaluations (LTE weeks 24-40).
  • The primary endpoint included the proportion of patients achieving ACR50 at week 14.

Results

Patient Characteristics
  • The mean ages ranged from 48.4-50.2 years with disease duration ranging from
    7.4-9.4 years.
  • Prior to study participation, approximately 5% of patients had received infliximab (n=36), etanercept (n=29), and/or adalimumab (n=36).
  • A total of 565 patients completed the primary study. Of these, 508 entered the LTE.

Safety
  • A total of 3 patients died through week 48: 1 each in the SIMPONI ARIA 2 mg/kg group, SIMPONI ARIA 4 mg/kg group, and the SIMPONI ARIA 4 mg/kg + MTX group. Two additional deaths (1 in the SIMPONI ARIA 2 mg/kg group and 1 in the SIMPONI ARIA 2 mg/kg + MTX group) were reported after week 48.
  • Eight malignancies were reported in patients receiving SIMPONI ARIA, 1 in the SIMPONI ARIA 2 mg/kg group, 2 in the 4 mg/kg group, 1 in the 2 mg/kg + MTX group, and 4 in the 4 mg/kg + MTX group.
  • Antibodies to golimumab were detected in 7% (43/613) of patients with evaluable samples through week 48. Of note, through week 48, concomitant use of MTX was associated with a lower incidence of antibodies to golimumab.

Data through week 48 are presented by actual treatment received, with AEs being attributed to the treatment received at the time of the event. Therefore, some patients are included in more than 1 column.
Abbreviations: AE, adverse event; GLM, golimumab; IR, infusion reaction; IV, intravenous; MTX, methotrexate; PBO, placebo; SAE, serious adverse event.
aCombined includes patients receiving SIMPONI ARIA 2 mg/kg or 4 mg/kg.
bCombined includes patients receiving SIMPONI ARIA 2 mg/kg or 4 mg/kg + MTX.
cIncludes patients receiving SIMPONI ARIA with or without MTX.

Phase 3 - GO-FURTHER

Weinblatt et al (2012)2,5-7 conducted a phase 3, multicenter, double-blind, placebo-controlled study to evaluate the efficacy and safety of SIMPONI ARIA in patients with active RA (≥6/66 swollen joints, ≥6/68 tender joints, CRP ≥1.0 mg/dL, RF and/or anti-CCP antibody positivity) despite stable MTX treatment (≥4 weeks at 15-25 mg/week) for at least 3 months.

Study Design/Methods

  • A total of 592 patients were randomized to 1 of 2 treatment groups: SIMPONI ARIA 2 mg/kg + MTX (n=395) or placebo + MTX (n=197). Infusions were administered at weeks 0, 4, and every 8 weeks thereafter through week 100.
  • At week 16, nonresponders (<10% improvement from baseline in both tender and swollen joint counts) in the placebo group entered early escape to receive SIMPONI ARIA 2 mg/kg (weeks 16, 20, and every 8 weeks thereafter).
  • At week 24, all remaining patients in the placebo group began receiving SIMPONI ARIA 2 mg/kg.
  • The primary endpoint was the proportion of patients achieving an ACR20 response at week 14.

Results

Patient Characteristics
  • A majority of patients were Caucasian (80.4%) and female (81.6%) with a median age of 52 years.
  • A majority of patients (96.3%; 570/592) completed the study through week 24. At week 16, 34.5% of patients in the placebo + MTX group entered early escape and received SIMPONI ARIA.
  • Through week 112, a majority of patients (82% [486/592]) continued the study. Of the patients that withdrew from the study (n=106), 44 discontinued due to AEs and 12 discontinued due to lack of efficacy.

Safety
  • Through week 24, serious AEs were reported in 4.1% of patients in the combined SIMPONI ARIA + MTX group compared to 2.0% of patients receiving MTX alone. Serious infections were reported in 0.9% (4/463) and 0.0% (0/197) of patients in these groups, respectively.
  • Through week 112, 3 patients developed tuberculosis and 2 patients developed a serious opportunistic infection.
  • Antibodies to golimumab were detected in 6.7% (37/553) of patients receiving SIMPONI ARIA through week 100.

LITERATURE SEARCH

A literature search of MEDLINE®, EMBASE®, BIOSIS Previews®, and DERWENT® (and/or other resources, including internal/external databases) was conducted on 28 January 2025.

Summarized in this response are relevant data from the pivotal phase 3 controlled clinical trials.
