A long-term extension study of filgotinib showed consistent safety profile and sustained efficacy with the drug for up to four years. The DARWIN 3 study, for patients who previously completed either the 24-week DARWIN 1 study (filgotinib + MTX) or the DARWIN 2 study (filgotinib monotherapy), enrolled 739 patients with RA. At the time of analysis, 440 patients had received four years or more of filgotinib. Exposure-adjusted incidence rate per 100 patient-years-of-exposure for TEAEs was 24.6 i...

JAKi are approved in various immune-mediated inflammatory diseases. With five JAKi now licensed, this paper reviews key points to consider in their use to assist clinicians, patients, and other stakeholders once the decision is made to commence JAKi. The consensus was developed by a Steering Committee and an expanded Task Force using EULAR standard operating procedures. The committee included patients as well as experts in rheumatology, gastroenterology, haematology, dermatology, and infectious ...

This integrated Phase III safety analysis of UPA showed that UPA had a similar profile to ADA and MTX for serious infections, malignancies, and thromboembolic events. Patients receiving UPA had increased risk of HZ and creatine phosphokinase elevation versus ADA. This integrated Phase III safety analysis of UPA examined >3500 RA patients and 4000 patient-years of exposure. Data were pooled from 3834 patients in SELECT-NEXT, SELECT-BEYOND, SELECT-MONOTHERAPY, SELECT-COMPARE and SELECT-EARLY s...

Reports from clinical trials and the US Corrona RA registry showed that serious infection event (SIE) incidence was higher in older versus younger patients with RA receiving 10 mg BID of TOF and ADA, however, SIE risk was similar between age groups with TOF 5 mg BID and ADA. Data were collected from Phase II–IV tofacitinib studies, and the US Corrona RA registry. The clinical data set evaluated patients receiving TOF 5 and 10 mg BID versus TNFi (ADA/ETN) in RA patients aged ≥50 years. ...

Baricitinib, an oral selective JAK1 and JAK2 inhibitor,8 demonstrated significant clinical efficacy in phase 3 RA trials. Pooled data from these trials, including a long-term extension (LTE), inform the safety profile for baricitinib, mainly to evaluate the incidence of infection in patients with active rheumatoid arthritis (RA), with a focus on serious infection, tuberculosis (TB), herpes zoster (HZ) and opportunistic infection (OI). The data collected were from eight double-blind randomised ...

RA is a chronic, life-long disease requiring long-term treatment. As such, it is important to understand the long-term safety profile of DMARDs. In this analysis, baricitinib maintained a stable safety profile during long-term exposure. This baricitinib safety analysis included integrated data from nine Phase 3, 2, and 1b clinical trials, and one long-term extension, with data up to 360 weeks. 3700 patients were included, with maximum follow-up of almost 7 years – representing an additio...

Patients with psoriatic arthritis (PsA) had similar safety profile with TOF to that of other systemic therapies in real-world settings, except for the known risk of HZ. Treatment recommendations from EULAR and GRAPPA for patients with PsA vary according to adverse prognostic risk factors, disease manifestations and responsiveness to prior treatment. Safety concerns for most PsA therapies include gastrointestinal AEs, hepatotoxicity, opportunistic infections (OIs) including TB, and SIEs. This s...

The results of ORAL Sequel suggest that the live zoster vaccine (LZV) may not provide adequate long-term protection in patients with RA receiving TOF. This LTE study enrolled 100 patients with RA, 14 weeks post LZV vaccination. Patients received either TOF 5 mg BID, or TOF 10 mg BID in addition to any background csDMARDs. Incidence rates and 95% CIs for HZ post-vaccination were calculated based on time to first event. Short-term varicella zoster vaccine (VZV) specific immunity was evaluated a...

Absolute serious infection rates were low. However, across the JAKinibs, the incidence of HZ is higher than expected for the population. While the risk was numerically greatest with BARI, indirect comparisons between the drugs did not demonstrate any significant difference in risk. How JAKinibs increase the risk of HZ reactivation is unclear, but how different JAKs interact in the immune response suggest that there may be differences in safety profiles between JAKinib drugs, underpinned by the...

How JAKinibs increase the risk of HZ reactivation is unclear. Roles of different JAKs in the immune response may suggest differences in safety profiles between drugs, underpinned by their differential JAK selectivity profiles. The authors undertook a systematic review and meta-analysis to evaluate SI and opportunistic indicator infections including HZ in RA Phase II/III clinic trials with JAKinibs. A literature review of RCT of TOF (5 mg BID), BARI (4 mg OD) and UPA (15 mg OD) was conducted. A...

Approximately two thirds of long-term BARI treated patients achieved satisfactory humoral and functional responses to 13-serotype pneumococcal conjugate vaccine (PCV-13), whereas tetanus toxoid vaccine (TTV) responses were less robust. Both RA management guidelines and recommendations suggest vaccinating patients with RA against pneumococcal disease with PCV-13 and PPSV-23. The inhibition of the JAK mediated signal transduction pathways in RA treatment could diminish vaccine responses. Given t...

In this integrated analysis, BARI showed an acceptable safety profile in Japanese patients with up to 3.2 years of exposure. Other than incidences of herpes zoster (HZ), no major differences were noted with BARI safety in Japanese patients with RA, compared to the patients in the integrated database. BARI has previously demonstrated significant clinical efficacy and acceptable safety. Japanese patients who participated in the BARI clinical development programme, were comparable to those from th...

The results of this analysis of patients with herpes zoster (HZ) within the global tofacitinib (TOF) RA programme suggest that there is likely to be a greater HZ risk in patients receiving TOF and glucocorticoids compared with patients receiving TOF monotherapy. The global TOF RA development programme comprised 2 Phase 1, 9 Phase 2, 6 Phase 3 and 2 long-term extension studies. These studies included 6192 patients; data were reviewed to identify cases of HZ. Crude incidence rates of number of pa...

Patients who were treated with tofacitinib in the RA clinical development programme were more likely to develop herpes zoster than were those who received placebo. Cases of herpes zoster reported by investigators in the Phase 2, Phase 3 and long-term extension studies of tofacitinib were evaluated. Herpes zoster was noted in 5% of tofacitinib-treated patients; only 7% of these cases were serious, no patients with herpes zoster died and only 10% permanently discontinued tofacitinib treatment.

The increased risk of serious infection among RA patients means vaccinations against pneumococcus and influenza are recommended in this group of patients. Studies evaluating immune response to these vaccines in conjunction with DMARD therapy can provide clinicians with important information relating to things such as timing of vaccination. This study aimed to assess the effect of tofacitinib on vaccine responses to PPSV-23 and the trivalent seasonal influenza vaccine in those whom tofacitinib...

It is well established that patients with RA are at an increased risk of herpes zoster (HZ). What is less well known is whether some of the newer therapies available for treatment of RA increase this risk. Tofacitinib has been reported to be associated with an increased risk of HZ and this study quantifies that risk and reviews potential factors that represent an increased risk. Using data from the tofacitinib RA development programme; phase 2, 3, and long-term extension clinical trials, over 20...
