Effect of Golimumab Dose Escalation in Japanese Patients With Rheumatoid Arthritis: Post-Hoc Analysis of Post-Marketing Surveillance Data.

ABSTRACT: INTRODUCTION:While dose escalation of golimumab has been used for patients with rheumatoid arthritis who demonstrate an inadequate response to the standard dose, its effectiveness has not been fully evaluated. The aim of this study was to assess the clinical outcome observed by dose escalation of golimumab for patients with rheumatoid arthritis in the daily clinical setting. METHODS:A post hoc analysis was performed of data from the 24-week post-marketing surveillance conducted in Japan (n?=?5154). A total of 301 patients with moderate or high disease activity at baseline who underwent dose escalation of golimumab were assessed for effectiveness at 24 weeks based on several variables, such as DAS28-CRP, SDAI, and CDAI, as well as for medication persistence through 24 weeks. In addition, the study population was stratified by the time to dose escalation, and effectiveness was likewise evaluated. Logistic regression analysis was performed to identify factors associated with a moderate/good EULAR response to golimumab at 24 weeks. RESULTS:Patients with golimumab dose escalation showed significant improvement of the clinical signs and symptoms of rheumatoid arthritis at 24 weeks, as indicated by reduction of the DAS28-CRP (?0.89), SDAI (?8.64), and CDAI (?8.28) scores. This result was relatively consistent across the subgroups stratified by the timing of dose escalation. According to Kaplan-Meier analysis, 78.1% of the patients continued to receive golimumab at 24 weeks, and this was also similar among the subgroups stratified by the time to dose escalation. Multivariate analysis identified male sex and previous biologic therapy as factors that were significantly associated with the clinical response at 24 weeks. CONCLUSION:In real-world clinical practice, improvement of disease activity was observed after uptitration of golimumab from 50 to 100 mg regardless of the timing. Male patients and biologic-naive patients were more likely to respond to dose escalation of golimumab. TRIAL REGISTRATION:UMIN-CTR, Identifier: UMIN000015895.

Project description:IntroductionThe safety of tofacitinib in psoriatic arthritis (PsA) and rheumatoid arthritis (RA) has been demonstrated in clinical studies of ≤ 4 and 9.5 years, respectively. Post-marketing surveillance (PMS) data for tofacitinib from spontaneous and voluntary adverse event (AE) reports have been published for RA, but not PsA. To inform the real-world safety profile of tofacitinib in PsA, we evaluated AE reports submitted to the Pfizer safety database (including RA data for context).MethodsEndpoints included AEs, serious AEs (SAEs), AEs of special interest (AESIs; serious infections, herpes zoster, cardiovascular events, malignancies, venous thromboembolism), and fatal cases. Exposure was estimated using IQVIA global commercial sales data. Number, frequency, and reporting rates (RRs; number of events/100 patient-years' [PY] exposure) were summarized by indication and formulation (immediate release [IR] 5 or 10 mg twice daily], modified release [MR] 11 mg once daily, or all tofacitinib). The data-collection period differed by indication (PsA: 14 December 2017 [US approval, IR/MR] to 6 November 2021; RA: 6 November 2012 [US approval, IR] to 6 November 2021; MR approval, 24 February 2016).ResultsA total of 73,525 case reports were reviewed (PsA = 5394/RA = 68,131), with 20,706/439,370 PY (PsA/RA) of exposure. More AEs were reported for IR versus MR (IR/MR: PsA = 8349/7602; RA = 137,476/82,153). RRs for AEs (IR/MR: PsA = 59.6/113.4; RA = 44.0/64.8) and SAEs (PsA = 8.1/13.6; RA = 8.0/9.5) were higher with MR versus IR. AE RRs (RA) in the first 4 years after IR approval were 95.9 (IR; 49,439 PY) and 147.0 (MR; 2000 PY). Frequency of SAEs, AESIs, and fatal cases was mostly similar across formulations and indications. The most frequently-reported AE Preferred Terms (PsA/RA) included drug ineffective (20.0%/17.8%), pain (9.7%/10.6%), condition aggravated (9.9%/10.5%), headache (8.8%/7.9%) and, for PsA, off-label use (10.5%/3.4%).ConclusionsTofacitinib PMS safety data from submitted AE reports were consistent between PsA and RA, and aligned with its known safety profile. Exposure data (lower MR versus IR; estimation from commercial sales data), reporting bias, reporter identity, and regional differences in formulation use limit interpretation.

Project description:IntroductionGolimumab is a human monoclonal antibody that inhibits tumor necrosis factor-α (TNF-α). Inhibition of TNF-α by golimumab inhibits the inflammatory response, thereby modulating the immune response in immune-mediated inflammatory diseases. Although the efficacy of golimumab has been demonstrated in randomized controlled trials (RCTs), various patient populations, such as those at high risk of infection, including those with latent tuberculosis and various comorbidities, or on co-administered medications, were excluded from the RCTs. Therefore, safety cannot be sufficiently evaluated by RCTs in the patient group with heterogenous characteristics. The aim of this study was to assess the safety and effectiveness of golimumab in patients with rheumatoid arthritis (RA), psoriatic arthritis (PsA), and ankylosing spondyloarthritis (AS) in a real-world setting in Korea.MethodsWe conducted an open-label, prospective, non-interventional study as post-marketing surveillance. Safety was evaluated by collecting and recording adverse events, and effectiveness was evaluated by assessing disease activity using DAS28-CRP, DAS28-ESR, ACR20, and ASAS20 outcome measures. Multiple logistic regression was performed to identify factors associated with the incidence of adverse events, and changes in disease activity scores from baseline were analyzed using the Wilcoxon signed-rank test.ResultsA total 673 patients were enrolled, of whom 621 were included in the safety analysis. During the study, 97 adverse drug reactions (ADRs) were reported in 62 patients (10.0%). The most frequently reported ADRs were related to infection, including nasopharyngitis (0.8%), upper respiratory tract infection (0.6%), and herpes zoster (0.5%). The mean (± standard deviation) changes from baseline in global disease activity at weeks 12 and 24 were - 3.37 ± 2.529 and - 3.68 ± 2.404, respectively, with statistical significance. In those patients with RA, 72.5 and 47.0% of individuals had a good response based on DAS28-CRP and DAS28-ESR outcomes at week 24. At week 24, 71.4% of patients with PsA had an ACR20 response and 72.9% of patients with AS had an ASAS20 response.ConclusionIn the real-world setting, golimumab was safe and effective in Korean patients with RA, PsA, and AS.

Project description:IntroductionWhile golimumab (GLM) has demonstrated efficacy in rheumatoid arthritis (RA), psoriatic arthritis (PsA), and ankylosing spondylitis (AS) in several randomized clinical trials with biologic-naïve patients, observational data from biologic-experienced patients are sparse. We aimed to assess the effectiveness of GLM used as the first-, second-, or at least third-line biologic agent in RA, PsA, and AS patients in a real-world setting.MethodsPost hoc analysis of the noninterventional, prospective, 24-month GO-NICE study of RA, PsA, and AS patients who initiated GLM 50 mg subcutaneously once monthly in a real-world setting in Germany.ResultsIn 1454 patients with RA, PsA, or AS, GLM was administered as the first-line (n = 305, 286, 292, respectively), second-line (n = 104, 136, 130, respectively), or at least third-line (n = 64, 79, 58, respectively) biologic agent. In RA patients (n = 473), the time since first diagnosis was 9.7, 10.1, and 14.3 years, respectively. The DAS28 score at BL was 5.0, 4.9, and 5.1 in patients using GLM as a first-, second-, and third-line biologic agent, respectively, and dropped significantly in all groups. After 3 months of treatment, 27.5%, 19.5%, and 14.5% of patients were in remission; the corresponding values after 24 months were 45.3%, 50.0%, and 33.3%, respectively. In PsA patients (n = 501), time since fist diagnosis was 12.4, 13.7, and 13.8 years, respectively. Based on PsARC, a response was achieved at 24 months in the first-, second-, and third-line use of GLM in 76.4%, 51.0%, and 50.0% of the patients. In AS patients (n = 480), the time since first diagnosis was 9.4, 9.8, and 12.4 years in patients using GLM as the first-, second-, and at least third-line biologic agent, respectively. After 24 months of treatment, the mean BASDAI scores decreased significantly (p < 0.001 vs. BL) to 2.1, 2.9, and 2.9 in the patients using GLM as the first-, second-, and at least third-line treatment, respectively.ConclusionsGolimumab is an effective treatment in patients with RA, PsA, and AS, irrespective of any pretreatment with biologic agents.Study registrationClinicalTrials.gov NCT01313858.
