Abstract Background: This multi-center, retrospective study aimed to clarify the factors affecting drug retention of the Janus kinase inhibitors (JAKi) baricitinib (BAR) and tofacitinib (TOF) in patients with RA.Methods: Patients were included as follows: females, 80.6%; age, 60.5 years; DAS28-ESR, 4.3; treated with either BAR (n = 166) or TOF (n = 185) and concomitant glucocorticoid (prednisolone [PSL] equivalent) 5.3 mg/day (46.7%) or methotrexate (MTX) 8.9 mg/week (60.7%); bDMARDs- or JAKi-switched cases (76.6%). The reasons for drug discontinuation were classified into four major categories: lack of effectiveness, toxic adverse events, non-toxic reasons and remission. The drug retention rate was estimated at 24 months using the Kaplan–Meier method and adjusted for potential confounders using multivariate Cox proportional hazards modelling.Results: Adjusted discontinuation rates for the corresponding reasons were as follows: lack of effectiveness (22.3%), toxic adverse events (13.3%), non-toxic reasons (7.2%) and remission (0.0%). Prior use of anti-interleukin-6 receptor antibody (aIL-6R) was significantly associated with discontinuation due to lack of effectiveness (P = 0.021). Ageing (P = 0.015), usage of PSL ≥5 mg/day (P = 0.017) and female sex (P = 0.041) were significantly associated with discontinuation due to toxic adverse events. Factors not associated with treatment discontinuation were: number of prior bDMARDs or JAKi, concomitant MTX usage, different JAKi and prior use of TNF inhibitor, CTLA4-Ig or other JAKi.Conclusions: Prior use of aIL-6R was associated with discontinuation due to lack of effectiveness, while ageing (≥75 years), PSL usage ≥5 mg/day, and female sex were associated with discontinuation due to toxic adverse events.

AbstractThis multi-center, retrospective study aimed to clarify the factors affecting drug retention of the Janus kinase inhibitors (JAKi) including baricitinib (BAR) and tofacitinib (TOF) in patients with RA. Patients were as follows; females, 80.6%; age, 60.5 years; DAS28-ESR, 4.3; treated with either BAR (n = 166) or TOF (n = 185); bDMARDs- or JAKi-switched cases (76.6%). The reasons for drug discontinuation were classified into four major categories. The drug retention was evaluated at 24 months using the Kaplan–Meier method and multivariate Cox proportional hazards modelling adjusted by confounders. Discontinuation rates for the corresponding reasons were as follows; ineffectiveness (22.3%), toxic adverse events (13.3%), non-toxic reasons (7.2%) and remission (0.0%). Prior history of anti-interleukin-6 receptor antibody (aIL-6R) ineffectiveness significantly increased the risk of treatment discontinuation due to ineffectiveness (p = 0.020). Aging (≥ 75 years) (p = 0.028), usage of PSL ≥ 5 mg/day (p = 0.017) and female sex (p = 0.041) significantly increased the risk of treatment discontinuation due to toxic adverse events. Factors not associated with treatment discontinuation were: number of prior bDMARDs or JAKi, concomitant MTX usage, difference of JAKi, and prior use of TNF inhibitor, CTLA4-Ig or other JAKi.

ABSTRACT Elderly patients with rheumatoid arthritis (RA) are frequently associated with higher disease activity and impaired physical function, although they show intolerance for conventional synthetic disease-modifying antirheumatic drugs (csDMARDs), such as methotrexate, because of their comorbidities. However, the present treatment recommendation based on randomized controlled trials is not distinguished by age or comorbidities. Therefore, this review aimed to investigate the efficacy and safety of biological DMARDs (bDMARDs) and Janus kinase inhibitors (JAKi) in elderly patients. Present bDMARDs, including tumor necrosis factor inhibitors (TNFi), cytotoxic T lymphocyte-associated antigen-4-immunoglobulin (abatacept), interleukin (IL)-6 receptor antibody (tocilizumab and salirumab), and anti-CD20 antibody (rituximab), may be similarly or slightly less effective or safe in elderly patients compared with younger patients. Oral glucocorticoid use, prolonged disease duration, and very old patients appear to be associated with an increased risk of adverse events, such as serious infection. Some recent cohort studies demonstrated that non-TNFi showed better retention than TNFi in elderly patients. Both TNFi and non-TNFi agents may not strongly influence the risk of adverse events such as cardiovascular events and malignancy in elderly patients. Regarding JAKi, the efficacy appears to be similar, although the safety (particularly for serious infections, including herpes zoster) may be attenuated by aging.

Drug Retention Rate

Background:In 20-30% of rheumatoid arthritis (RA) patients, the first biologic disease-modifying antirheumatic drugs (bDMARDs) (generally tumour necrosis factor inhibitors (TNFis)) is ineffective, and among the patients who do respond to therapy, 20% is faced with secondary ineffectiveness within the first 2 years of treatment [1]. In practice, when refractory RA is present, of which the definition implies previous use of at least two bDMARDs (generally TNFis), the next treatment choice often made is a bDMARD of another class (non-TNFis) [2]. On the other hand, patients who are inadequately responding to bDMARDs need new treatment options because subsequent bDMARD treatment reduces their response [3]. Janus Kinase inhibitors (JAKis) are the first targeted synthetic DMARDs (tsDMARD) licensed for the treatment of RA with comparable efficacy to bDMARDs. Unlike the single cytokine targeting approach of bDMARDs, JAKis are specifically designed to inhibit intracellular signalling molecules common to the receptors of multiple inflammatory cytokines implicated in RA pathogenesis.Objectives:Difficult-to-treat (D2T) RA is defined as refractory to two or more b/ts DMARDs with different mechanisms of action, with active and progressive disease, as published by Eular(4). We evaluated real world efficacy of approved JAKis and factors that may help to continue them in patients with D2T RA.Methods:Patients who had inadequate response to two or more bDMARDs (including both TNFis and non-TNFis) at our hospital by December 2019 were defined as D2T RA, and patients who switched to JAKis were retrospectively investigated. The drug retention rate was determined by Kaplan-Meier method, and the difference was tested by Logrank test. Multiple regression analysis was used as the statistical method to predict continuation of JAKis for more than 1 year, with patient background (age, gender, during the disease, number of bDMARDs used, with or without methotrexate and/or glucocorticoids, disease activity score assessing 28 joints using erythrocyte sedimentation rate’ presence of rheumatoid factor/anti-CCP antibody, matrix metalloproteinase 3 value, Health Assessment Questionnaire disability index) at the time of initiation as an explanatory variable.Results:A total of 915 bDMARDs had been administered to 394 RA patients. The retention rate of bDMARDs and the number of bDMARDs used were 89.3% and 1.48 bDMARDs at 1 year, 67.7% and 2.27 bDMARDs at 5 years, and 52.0% and 3.15 bDMARDs at 10 years, respectively. The retention rate of JAKis at 1 year was 60.2% in 65 patients with tofacitinib (TOF) and 67.2% in 70 patients with baricitinib (BAR) (P=0.38). Among them, the drug retention rate in D2T RA patients was 50.8% in 38 TOF patients and 66.3% in 35 BAR patients with no significant difference (P=0.30). There were no patient background factors that significantly predicted continuation at 1 year for any JAKis.Conclusion:Despite the limited number of patients and the retrospective nature of the study, TOF and BAR were shown to be effective options for D2T RA, regardless of patient background such as disease activity or number of bDMARDs used. Other JAKis and switches between JAKis need to be investigated in the future.References:[1]Schaeverbeke T, Truchetet ME, Kostine M et al.

Abstract Background: This multi-center, retrospective study aimed to clarify retention rates and reasons for discontinuation of 7 biological disease-modifying antirheumatic drugs (bDMARDs) and tofacitinib (TOF), one of the janus kinase inhibitors, in bDMARDs-naïve and bDMARDs-switched patients with rheumatoid arthritis (RA). Methods: This study assessed 3,897 patients and 4,415 treatment courses with bDMARDs and TOF from 2001 to 2019 (2,737 bDMARDs-naïve patients and 1,678 bDMARDs-switched patients [59.5% switched to their second agent], female 82.3%, baseline age 57.4 years, disease duration 8.5 years; rheumatoid factor positivity 78.4%; Disease Activity Score in 28 joints using erythrocyte sedimentation rate 4.3; concomitant prednisolone [PSL] dose 6.1 mg/day [42.4%], and methotrexate [MTX] dose 8.5 mg/week [60.9%]). Treatment courses included abatacept (ABT; n=663), adalimumab (ADA; n=536), certolizumab pegol (CZP; n=226), etanercept (ETN; n=856), golimumab (GLM; n=458), infliximab (IFX; n=724), tocilizumab (TCZ; n=851), and TOF (n=101/only bDMARDs-switched cases). Drug discontinuation reasons (categorized into lack of effectiveness, toxic adverse events, non-toxic reasons, or remission) and rates were estimated at 36 months using the Gray’s test, and statistically evaluated after adjusted by potential clinical confounders (age, sex, disease duration, concomitant PSL and MTX usage, starting date, and number of switched bDMARDs) using the Fine-Gray model. Results: Cumulative incidence of drug discontinuation for each reason was as follows: lack of effectiveness in the bDMARDs-naïve group (from 13.7% [ABT] to 26.9% [CZP]; P<0.001 between agents) and the bDMARDs-switched group (from 18.9% [TCZ] to 46.1% [CZP]; P<0.001 between agents). Toxic adverse events in the bDMARDs-naïve group (from 4.6% [ABT] to 11.2% [ETN]; P<0.001 between agents) and the bDMARDs-switched group (from 5.0% [ETN] to 15.7% [TOF]; P=0.004 between agents). Remission in the bDMARDs-naïve group (from 2.9% [ETN] to 10.0% [IFX]; P<0.001 between agents) and the bDMARDs-switched group (from 1.1% [CZP] to 3.3% [GLM]; P=0.9 between agents). Conclusions: Remarkable differences were observed in drug retention of 7 bDMARDs and TOF between bDMARDs-naïve and bDMARDs-switched cases.

ObjectivesTo evaluate in a multicentric Italian cohort of patients with psoriatic arthritis (PsA) on secukinumab followed for 24 months: (1) the long-term effectiveness and safety of secukinumab, (2) the drug retention rate and minimal disease activity (MDA), (3) differences in the outcomes according to the biological treatment line: biologic-naïve patients (group A) versus multifailure (group B) patients.MethodsConsecutive patients with PsA receiving secukinumab were evaluated prospectively. Disease characteristics, previous/ongoing treatments, comorbidities and follow-up duration were collected. Disease activity/functional/clinimetric scores and biochemical values were recorded at baseline (T0), 6(T6), 12(T12) and 24(T24) months. Effectiveness was evaluated overtime with descriptive statistics; multivariate Cox and logistic regression models were used to evaluate predictors of drug-discontinuation and MDA at T6. Infections and adverse events were recorded.Results608 patients (41.28% men; mean (SD) age 52.78 (11.33)) were enrolled; secukinumab was prescribed as first-line biological treatment in 227 (37.34%) patients, as second (or more)-line biological treatment in 381 (62.66%). Effectiveness of secukinumab was shown with an improvement in several outcomes, such as Ankylosing Spondylitis Disease Activity Score (T0=3.26 (0.88) vs T24=1.60 (0.69) ;p=0.02) and Disease Activity Index for Psoriatic Arthritis (T0=25.29 (11.14) vs T24=7.69 (4.51); p<0.01). At T24, group A showed lower Psoriasis Area Severity Index (p=0.04), erythrocyte sedimentation rate and C reactive protein (p=0.03 ;p=0.05) and joint count (p=0.03) compared with group B. At T24, MDA was achieved in 75.71% of group A and 70.37% of group B. Treatment was discontinued in 123 (20.23%) patients, mainly due to primary/secondary loss of effectiveness, and in 22 due to adverse events. Retention rate at T24 was 71% in the whole population, with some difference depending on secukinumab dosage (p=0.004) and gender (p=0.05).ConclusionsIn a real-life clinical setting, secukimumab proved safe and effective in all PsA domains, with notable drug retention rate.
