Dose Adjustment of Methotrexate Administered Concomitantly with Golimumab for Rheumatoid Arthritis in Japanese Real-World Clinical Settings.

ABSTRACT:

Introduction

The combination of methotrexate (MTX) with biological disease-modifying antirheumatic drugs (bDMARDs) is a recommended treatment option for rheumatoid arthritis (RA) patients showing an inadequate response to MTX monotherapy. However, the adequate dose of MTX, especially in long-term treatment with bDMARDs/MTX combination therapy, remains under-addressed. Since RA patients require long-term treatment, we examined the effects of using golimumab (GLM) in the long run as well as its persistency and associated factors.

Methods

We used the Japan Medical Data Center Inc. (JMDC) administrative claims data of 489 patients receiving GLM therapy for calculating the persistency in patients with constant, reduced, or escalated MTX dosing. The factors associated with GLM persistency were assessed using Cox proportional hazard modeling, controlling for the dose adjustment of concomitant MTX, age, sex, RA disease period, and the initial dose of GLM or concomitant MTX during GLM/MTX combination therapy.

Results

During GLM/MTX combination therapy, up to 52% of patients were reported to experience dose adjustments of concomitant MTX treatment (i.e., dose reduction and escalation in 34% and 18% of patients, respectively). Persistency was similar in the MTX dose-reduction patients and the MTX dose-constant patients. In the Cox proportional hazard model, no significant differences were observed in association with GLM persistency, including with respect to MTX dose adjustment.

Conclusions

GLM prescription was continued in 80% or more (1 year) and 50% or more (3 years) of RA patients receiving reduced concomitant MTX dosing, suggesting that MTX dose adjustment (including MTX reduction) could be considered in GLM/MTX combination therapy.

Project description:BACKGROUND:Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by systemic inflammatory status, joint destruction, disability, and pain. Methotrexate (MTX) has been confirmed to reduce disease activity and delay or stabilize the development of bone erosions. However, major drawbacks are that patients show great interindividual variability in response to MTX and the unpredictable occurrence of side effects. A strategy for personalized MTX treatment to predict its efficacy and toxicity has not yet been determined. To establish personalized MTX therapy in Japanese patients with rheumatoid arthritis, we performed a preliminary study for predicting better methotrexate efficacy including single-nucleotide polymorphisms (SNPs) for MTX-related transporters/enzymes. METHODS:Disease control status (good or poor) was judged by the number of Disease Activity Scores (DAS28) of <2 for 6-12 months. The response index R was calculated by the improved area under the curve (AUC) of the DAS28 score for 0-3 or 0-6 months by dividing the cumulative dose of MTX during 0-3 or 0-6 months, respectively. Genotyping of alleles of RFC1 80G?>?A, RFC1 -43 T?>?C, FPGS 1994G?>?A, GGH 401C?>?T, MTHFR 1298A?>?C, and TYMS 3'-UTR (-6/+6) was performed using the real-time PCR system. RESULTS:Seven of 21 patients were judged as good responders in terms of disease control, and the remainder as poor responders. For 0-3 months after starting MTX administration, the median cumulative dose and improved DAS28 AUC in the good and poor response groups were 96.0 mg and 25.4 and 118.0 mg and 23.4, respectively. For 0-6 months, the median cumulative dose and improved DAS28 AUC in the good and poor response groups were 192.0 mg and 51.0 and 214.0 mg and 47.6, respectively. Statistically significant differences between the 2 groups in the 0-6-month period were observed in DAS28 AUC improvement and index R. A slight tendency for a correlation between G/G genotypes and A allele genotypes in RFC1 80 genotypes was observed, although it did not reach statistical significance. CONCLUSION:This study suggested that aggressive RA treatment with MTX from the early period of administration is necessary to obtain a good response after 6 months, although no SNPs predicting a better treatment response to MTX were identified.

Project description:Objective:To assess methotrexate (MTX) adherence using the Medication Event Monitoring System (MEMS) and characterize associations with adherence in patients with rheumatoid arthritis (RA). Methods:Eligible patients participated in Forward, the National Databank for Rheumatic Diseases, and recently (12 months or sooner) initiated oral MTX. MEMS was used to compile MTX weekly dosing over 24 weeks. The Beliefs about Medicines Questionnaire (BMQ) was completed, and baseline demographics and disease characteristics obtained. MTX adherence (percentage of weeks dose taken correctly), implementation (percentage of weeks dose taken correctly from initiation until last dose), and persistence (duration from initiation to last dose) were calculated. Analyses measured associations between patient characteristics and adherence, modeled using logistic generalized estimating equations and censored Poisson regression, and persistence modeled using Cox regression. Results:Overall, 60 of 119 eligible patients were included in the analysis. MTX adherence, implementation, and persistence were 75%, 80%, and 83%, respectively, at 24 weeks. Demographics and disease characteristics were generally similar between patients with 1 week or less and 2 weeks or more of missed MTX. Unemployment, less disability, higher Patient Global scores, and no prior disease-modifying antirheumatic drug (DMARD) use were associated with correct dosing. No significant differences in adherence were observed between patients receiving concomitant MTX versus MTX monotherapy, and biologic DMARD-experienced versus biologic DMARD-naïve patients. Higher scores in BMQ Specific Necessity (indicating a greater belief in the necessity of the medication) was associated with a decreased likelihood of dosing at an interval shorter than prescribed (odds ratio 0.89). Conclusion:Even in a participatory group over a short period, MTX adherence was suboptimal and associated with certain demographics, medication experience, and beliefs about medicines. This suggests a need for screening and alternative treatment opportunities in nonadherent MTX patients with RA.

Project description:ObjectiveTo evaluate the safety and efficacy of golimumab through 5 years in adults with active rheumatoid arthritis (RA) who had not previously received methotrexate (MTX).MethodsIn the GO-BEFORE study, 637 MTX-naive adult patients with active RA were randomized (1:1:1:1) to placebo?+?MTX (group 1), golimumab 100 mg?+?placebo (group 2), golimumab 50 mg?+?MTX (group 3), or golimumab 100 mg?+?MTX (group 4). Inadequate responders in groups 1, 2, and 3 entered early escape at week 28 to golimumab 50 mg?+?MTX, golimumab 100 mg?+?MTX, or golimumab 100 mg?+?MTX, respectively; remaining patients in group 1 could cross over to golimumab 50 mg?+?MTX at week 52. Assessments included the American College of Rheumatology 20%/50%/70% improvement criteria (ACR20/50/70) response, the Disease Activity Score in 28 joints (DAS28) using C-reactive protein (CRP) level, and the modified Sharp/van der Heijde score (SHS). Efficacy was analyzed using an intent-to-treat (ITT) analysis. Pharmacokinetics and immunogenicity were evaluated at selected visits.ResultsA total of 422 patients completed golimumab treatment through week 256. At week 256, 72.8%, 54.6%, and 38.0% of all patients in the full ITT population (n?=?637) had an ACR20/50/70 response, respectively; 84.1% had a good or moderate DAS28-CRP response; and 72.7% had a clinically meaningful improvement in physical function. Radiographic progression was minimal in all treatment groups through week 256, and the overall mean change from baseline in SHS was 1.36. Serum trough golimumab concentrations were approximately dose proportional and maintained through week 256. Antibodies to golimumab occurred in 9.6% of patients through week 256. Infections were the most common type of adverse event (AE); 204 of 616 patients (33.1%) had ?1 serious AE.ConclusionClinical efficacy with golimumab treatment was maintained through week 256 of the GO-BEFORE trial of MTX-naive RA patients. No unexpected AEs occurred; safety results through 5 years are consistent with earlier reports.

Project description: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:OBJECTIVE:To evaluate the safety and efficacy of intravenous golimumab + methotrexate (MTX) in patients with active rheumatoid arthritis (RA) aged <?65?years and those ??65?years who were enrolled in the GO-FURTHER study. METHODS:In the phase III, double-blind, randomized, placebo-controlled GO-FURTHER trial, patients with active RA were randomized to intravenous (IV) golimumab 2?mg/kg + MTX or placebo + MTX at weeks 0 and 4, then every 8?weeks thereafter (with crossover to golimumab at week 16 [early escape] or week 24 [per-protocol]). The final golimumab infusion was at week 100. Assessments included American College of Rheumatology (ACR) 20/50/70 response criteria. Efficacy and adverse events (AEs) were monitored through 2 years. Efficacy and AEs were summarized for patients aged <?65?years or ??65?years; AEs were also summarized for patients < or ??70?years and patients < or ??75?years. RESULTS:In GO-FURTHER, 592 patients were randomized to receive placebo (n?=?197) or golimumab (n?=?395), 515 were aged <?65?years and 77 were ??65?years. At week 24, ACR20 response rates were greater for golimumab + MTX patients compared with placebo + MTX for patients <?65?years (61.6% vs 31.3%, p?<?0.001) and those ??65?years (69.5% vs 33.3%; p?<?0.01). Infections were the most common AE through week 112 (51.6% in patients <?65?years; 55.3% in patients ??65?years); upper respiratory infections were the most common infection in patients <?65?years (13.2%) and those ??65?years (11.8%). Serious AEs occurred in 17.7% in patients <?65?years and 25.0% of patients ??65?years and included malignancies, pneumonia, fractures, acute pancreatitis, cellulitis, and bacterial arthritis. CONCLUSIONS:In GO-FURTHER, ACR response rates were similar between patients <?65?years and patients ??65?years within each treatment group. AEs in elderly patients were similar to the known safety profile of IV golimumab. Immunosenescence is known to increase the risk of infections in the elderly. Elderly patients had a numerically higher incidence of serious infections. Six malignancies occurred in golimumab-treated patients, all in patients <?65?years.

Project description:INTRODUCTION:Golimumab has been proven as an effective treatment for rheumatoid arthritis in clinical trials. However, there is a scarcity of data regarding its use in elderly patients in a real-world setting. This study aims to evaluate the safety, effectiveness, and treatment persistence of golimumab in elderly Japanese patients (? 75 years) with rheumatoid arthritis. METHODS:This study was a post hoc analysis of post-marketing surveillance data on 5137 Japanese patients with active rheumatoid arthritis who received golimumab for 24 weeks. The study population was divided into two age groups (younger: < 75 years and elderly: ? 75 years), and the safety, effectiveness, and treatment persistence of golimumab were assessed. Also, the reasons for discontinuing golimumab treatment were analyzed by multi-logistic regression. RESULTS:During golimumab treatment over 24 weeks, younger and elderly groups exhibited comparable improvement of disease activity as measured by EULAR response criteria with similar overall rates of adverse events. However, the survival curve of golimumab for elderly patients was significantly different from that for younger patients due largely to the discontinuation at 4 weeks. The most common reason for discontinuation in elderly patients was patient choice, while it was disease progression in younger patients. Analysis of elderly patients who discontinued treatment by their own decision identified EULAR good response as a factor associated with continuation of golimumab treatment whereas no predictive factor associated with discontinuation was identified. CONCLUSIONS:The safety and effectiveness of golimumab treatment in elderly Japanese patients aged 75 years or older were comparable to those in younger patients in real-world clinical practice. Analysis of the survival curves suggested that continuous use of golimumab might further improve clinical benefit of golimumab in elderly patients, underpinning the importance of effective communication between physicians and elderly patients based on the treat-to-target strategy.

Project description:IntroductionThe persistence of golimumab (GLM) treatment in Japanese patients with rheumatoid arthritis (RA) has been evaluated previously, but evidence of long-term real-world use is lacking. This study assessed the long-term persistence of GLM use, its influencing factors, and impact of prior medications in patients with RA in actual clinical practice in Japan.MethodsThis is a retrospective cohort study of patients with RA using data from a hospital insurance claims database in Japan. The identified patients were stratified as only GLM treatment (naïve), had one biological disease-modifying anti-rheumatic drug (bDMARD)/Janus kinase (JAK) inhibitor treatment prior to GLM [switch (1)] and had at least two bDMARDs/JAK prior to GLM treatment [switch (≥ 2)]. Patient characteristics were evaluated using descriptive statistics. Kaplan-Meier survival and Cox regression methods were used to analyze GLM persistence at 1, 3, 5, and 7 years and the associated factors. Treatment differences were compared using a log-rank test.ResultsGLM persistence rate in the naïve group was 58.8%, 32.1%, 21.4%, and 11.4% at 1, 3, 5, and 7 years, respectively. Overall persistence rates in the naïve group were higher than in switch groups. Higher GLM persistence was observed among patients aged 61-75 years and those concomitantly using methotrexate (MTX). Also, women were less likely to discontinue treatment compared to men. Higher Charlson Comorbidity Index score, initial GLM dose of 100 mg, and switch from bDMARDs/JAK inhibitor were related to a lower persistence rate. As a prior medication, infliximab showed the longest persistence for subsequent GLM, and using this as a reference, tocilizumab, sarilumab, and tofacitinib subgroups had significantly shorter persistence, respectively (p = 0.001, 0.025, 0.041).ConclusionThis study presents the long-term real-world results for persistence of GLM and its potential determinants. These most recent and long-term observations demonstrated that GLM and other bDMARDs continue to benefit patients with RA in Japan.
