Increased risk of herpes zoster with tofacitinib treatment in Korean patients with rheumatoid arthritis: a single-center prospective study.

ABSTRACT: We aimed to determine the risk of herpes zoster (HZ) in Korean rheumatoid arthritis (RA) patients on tofacitinib compared with tumor necrosis factor inhibitor (TNFi) treatment. From the prospective cohorts of RA patients who started tofacitinib or TNFi in an academic referral hospital in Korea, patients who started tofacitinib between March 2017 and May 2021 and those who started TNFi between July 2011 and May 2021 were included. Baseline characteristics of tofacitinib and TNFi users were balanced through inverse probability of treatment weighting (IPTW) using the propensity score including age, disease activity of RA and medication use. The incidence rate of HZ in each group and incidence rate ratio (IRR) were calculated. A total of 912 patients were included: 200 tofacitinib and 712 TNFi users. There were 20 cases of HZ among tofacitinib users and 36 among TNFi users during observation period of 331.4 person-years (PYs) and 1950.7 PYs, respectively. In IPTW analysis with a balanced sample, IRR of HZ was 8.33 (95% confidence interval 3.05-22.76). Tofacitinib use increased the risk of HZ compared with TNFi in Korean patients with RA, but the rate of serious HZ or permanent discontinuation of tofacitinib due to HZ event was low.

Project description:ObjectivePatients with rheumatoid arthritis (RA) are at increased risk for herpes zoster (HZ) (i.e., shingles). The aim of this study was to determine whether treatment with tofacitinib increases the risk of HZ in patients with RA.MethodsHZ cases were identified as those reported by trial investigators from the databases of the phase II, phase III, and long-term extension (LTE) clinical trials in the Tofacitinib RA Development Program. Crude incidence rates (IRs) of HZ per 100 patient-years (with 95% confidence intervals [95% CIs]) were calculated by exposure group. Logistic regression analyses were performed to evaluate potential risk factors for HZ (e.g., age, prednisone use).ResultsAmong 4,789 participants, 239 were identified as having tofacitinib-associated HZ during the phase II, phase III, and LTE trials, of whom 208 (87%) were female and whose median age was 57 years (range 21-75 years). One HZ case (0.4%) was multidermatomal; none of the cases involved visceral dissemination or death. Twenty-four patients with HZ (10%) permanently discontinued treatment with tofacitinib, and 16 (7%) were either hospitalized or received intravenous antiviral drugs. The crude HZ IR across the development program was 4.4 per 100 patient-years (95% CI 3.8-4.9), but the IR was substantially higher within Asia (7.7 per 100 patient-years, 95% CI 6.4-9.3). Older age was associated with HZ (odds ratio 1.9, 95% CI 1.5-2.6), and IRs for HZ were similar between patients receiving 5 mg tofacitinib twice daily (4.4 per 100 patient-years, 95% CI 3.2-6.0) and those receiving 10 mg twice daily (4.2 per 100 patient-years, 95% CI 3.1-5.8). In the phase III trials among placebo recipients, the incidence of HZ was 1.5 per 100 patient-years (95% CI 0.5-4.6).ConclusionIn the Tofacitinib RA Development Program, increased rates of HZ were observed in patients treated with tofacitinib compared with those receiving placebo, particularly among patients within Asia. Complicated HZ among tofacitinib-treated patients was rare.

Project description:IntroductionRisk of herpes zoster (HZ) is increased with Janus kinase inhibitor use. We evaluated clinical study data relating to HZ management in patients with rheumatoid arthritis (RA) or psoriatic arthritis (PsA) receiving tofacitinib.MethodsThis post hoc analysis included data from 21 RA and 3 PsA clinical studies; data were pooled for tofacitinib doses. Outcomes of HZ events (serious and non-serious) and tofacitinib treatment changes were evaluated in response to first and second HZ events. Median time to resolution was stratified by dermatomal involvement, history of HZ prior to tofacitinib, changes to tofacitinib treatment, anti-viral and corticosteroid use, and tofacitinib dose.ResultsSeven hundred eighty-three (11.1%, N = 7061) patients with RA experienced ≥ 1 HZ event, 63 (8.0%) of whom had ≥ 2 HZ events. In patients with PsA, 36 (4.6%, N = 783) experienced ≥ 1 HZ event, 1 (2.8%) of whom had ≥ 2 HZ events. For most HZ events, tofacitinib treatment was unchanged or temporarily discontinued. The majority of patients received anti-viral treatment, most within 3 days of onset. Post-herpetic neuralgia developed in 6.9% and 3.2% of patients with RA with first and second events, respectively, and in 2.8% of patients with PsA with a first event. Most first and second events resolved (RA: 97.6% and 96.8%, respectively; PsA: 94.4% and 100%, respectively). Median time to resolution was 22.0 days for first and 15.0 days for second events for RA and 20.5 days for first and 11.0 days for second events (n = 1) for PsA. Time to resolution of first events for RA and PsA was generally numerically shorter for patients with single dermatomal HZ, history of HZ, or anti-viral use versus those without.ConclusionAmong patients receiving tofacitinib, recurrent events were more common in patients with RA versus PsA; HZ duration was shorter for repeat events.Trial registrationNCT01262118, NCT01484561, NCT00147498, NCT00413660, NCT00550446, NCT00603512, NCT00687193, NCT01164579, NCT00976599, NCT01059864, NCT01359150, NCT02147587, NCT00960440, NCT00847613, NCT00814307, NCT00856544, NCT00853385, NCT01039688, NCT02187055, NCT00413699, NCT00661661, NCT01877668, NCT01882439, NCT01976364.

Project description:ObjectivePatients with rheumatoid arthritis (RA) are at increased risk of herpes zoster (HZ), and the risk appears to be increased in patients treated with tofacitinib. The aim of this study was to evaluate whether concomitant treatment with conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) or glucocorticoids (GCs) contributes to the increased risk of HZ in RA patients treated with tofacitinib.MethodsHZ cases were identified from the databases of 2 phase I, 9 phase II, 6 phase III, and 2 long-term extension studies of tofacitinib in RA patients. Crude incidence rates (IRs) of all HZ events (serious and nonserious) per 100 patient-years (with 95% confidence intervals [95% CIs]) were calculated for unique patients. Within phase III studies, we described HZ rates according to concomitant csDMARD treatment and baseline GC use. A multivariable Cox proportional hazards regression model was used to evaluate HZ risk factors across studies.ResultsAcross all studies (6,192 patients; 16,839 patient-years), HZ was reported in 636 tofacitinib-treated patients (IR 4.0, 95% CI 3.7-4.4). In most cases (93%), HZ was classified as nonserious, and the majority of patients (94%) had involvement of only 1 dermatome. HZ IRs varied across regions, from 2.4 (95% CI 2.0-2.9) in Eastern Europe to 8.0 (95% CI 6.6-9.6) in Japan and 8.4 (95% CI 6.4-10.9) in Korea. Within phase III studies, HZ IRs varied according to tofacitinib dose, background csDMARD treatment, and baseline use of GCs. The IRs were numerically lowest for monotherapy with tofacitinib 5 mg twice daily without GCs (IR 0.56 [95% CI 0.07-2.01]) and highest for tofacitinib 10 mg twice daily with csDMARDs and GCs (IR 5.44 [95% CI 3.72-7.68]). Age, GC use, tofacitinib dose, and enrollment within Asia were independent risk factors for HZ.ConclusionPatients receiving treatment with tofacitinib and GCs appear to have a greater risk of developing HZ compared with patients receiving tofacitinib monotherapy without GCs.
