In these 3 placebo-controlled trials, efficacy of ustekinumab in the treatment of axSpA was not demonstrated. The safety profile was consistent with that of studies in other indications. This article is protected by copyright. All rights reserved.

ObjectiveTo evaluate the safety and efficacy of intravenous (IV) golimumab treatment in psoriatic arthritis (PsA).MethodsIn this phase III, randomized, double‐blind, placebo‐controlled trial, patients were randomly assigned to receive IV placebo (n = 239) or golimumab at 2 mg/kg (n = 241) at weeks 0, 4, 12, and 20. The primary end point was the proportion of patients meeting the American College of Rheumatology 20% improvement criteria (achieving an ACR20 response) at week 14. Controlled secondary end points included change from baseline in Health Assessment Questionnaire disability index (HAQ DI) score at week 14, proportions of patients with ACR50 and ACR70 responses and ≥75% improvement on the Psoriasis Area and Severity Index (a PASI75 response) at week 14, and change from baseline at week 24 in the total modified Sharp/van der Heijde score (SHS) with modifications for patients with PsA.ResultsAt week 14, an ACR20 response was achieved by 75.1% of patients in the golimumab group compared with 21.8% of patients in the placebo group (P < 0.001). Greater proportions of golimumab‐treated patients had an ACR50 response (43.6% versus 6.3%), an ACR70 response (24.5% versus 2.1%), and a PASI75 response (59.2% versus 13.6%) at week 14 (P < 0.001 for all). Patients in the golimumab group had greater mean changes at week 14 in HAQ DI score (–0.60 versus –0.12; P < 0.001). At week 24, the mean change in total PsA‐modified SHS was –0.4 in the golimumab group and 2.0 in the placebo group (P < 0.001). Through week 24, 40.6% of patients in the placebo group and 46.3% of patients in the golimumab group had ≥1 adverse event (AE); infections were the most common type.ConclusionPatients receiving IV golimumab at 2 mg/kg had significantly greater improvements in the signs and symptoms of PsA and less radiographic progression through week 24. AEs were consistent with those seen with other anti–tumor necrosis factor agents.

Adalimumab-treated patients who discontinued therapy and subsequently relapsed had a good likelihood of regaining clinical efficacy following adalimumab reinitiation.

ObjectivesAssess golimumab's long-term efficacy/safety in psoriatic arthritis (PsA).MethodsAdults 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).Results126/405 (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).ConclusionsLong-term golimumab safety/efficacy in PsA was demonstrated through 5 years.Trial registration numberNCT00265096.

Objective.To evaluate the safety and efficacy of intravenous golimumab (GOL) in patients with active ankylosing spondylitis (AS).Methods.In a phase III, randomized, double-blind, placebo (PBO)-controlled trial, 208 patients were randomized (1:1) to intravenous (IV) infusions of GOL 2 mg/kg (n = 105) at weeks 0, 4, 12, and every 8 weeks, or PBO (n = 103) at weeks 0, 4, and 12, with crossover to GOL at Week 16. The primary endpoint was ≥ 20% improvement from baseline in the Assessment of Spondyloarthritis International Society Criteria (ASAS20) at Week 16. Secondary endpoints included ASAS40, ≥ 50% improvement in the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI50), and change in the Bath Ankylosing Spondylitis Functional Index (BASFI) at Week 16. Safety was monitored through Week 28.Results.Significantly greater proportions of GOL-treated patients had ASAS20 response at Week 2 (37.1% vs 19.4%; p = 0.005) and at Week 16 (73.3% vs 26.2%; p < 0.001). At Week 16, 41.0% of those receiving GOL achieved BASDAI50 compared with 14.6% of those taking PBO (p < 0.001), and the GOL group had greater mean improvement in BASFI (−2.4 vs −0.5; p < 0.001). Through Week 16, 23.3% of patients in the PBO group and 32.4% of patients in the GOL group had ≥ 1 adverse event (AE); infections being the commonest type of AE. Through Week 28, two GOL-treated patients had a serious AE.Conclusion.GOL 2 mg/kg administered IV at weeks 0, 4, and every 8 weeks significantly reduced the signs and symptoms of AS in adults. AE were consistent with other antitumor necrosis factor therapies, with no new safety signals (Clinicaltrials.gov: NCT02186873).
