BTK is involved in both adaptive and innate immune responses and mediates signalling of several immune receptors of relevance to RA and SLE pathogenesis. Targeting BTK is a promising approach therefore for autoimmune disorders with aberrant B cell responses. Evobrutinib is a novel, highly specific, and irreversible BTK inhibitor. In vivo and animal models showed that evobrutinib modulated B cell and innate immune cell activation, was efficacious, and prevented joint damage. The potency of evobru...

Existing evidence from RCTs indicated no significant change in CV risk for JAK inhibitor (JAKinib) treated RA patients in a short-term perspective compared to placebo.Patients with RA have an elevated risk of CV morbidity and mortality, which cannot be fully explained by traditional CV risk factors. Reaching remission or LDA in order to reduce CV events (CVE) is encouraged in the current EULAR recommendations. JAKinibs and their roles in the modulation of CV risk remain undetermined. This study ...

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 p...

TOF 5 mg and 10mg BID demonstrated a consistent safety profile and sustained efficacy for up to 9.5 years in this open-label LTE ORAL Sequel study.TOF 5 mg and 10 mg BID demonstrated consistent safety (as monotherapy and combination therapy) and efficacy within this open-label LTE study of RA patients. As RA requires long-term treatment, it’s important to assess the long-term efficacy and safety of RA therapies to understand the potential lifelong impact on patient health and quality of life. Th...

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 the...

The risk of TB and hepatitis B virus (HBV) appears to be no greater with TOF than with bDMARDs. Most cases of TB during TOF studies occurred in regions with high background rate of TB, including east Asian countries. TOF is also associated with a higher rate of herpes zoster (HZ) compared with bDMARDs. DMARDs used to treat RA can increase the risk of infections by causing a degree of immunosuppression. A range of bacterial and viral infections have been observed in association with DMARD therapy...

Differences in baseline characteristics and numerical differences in IR of SI between ABA, RRTX and TOZ were observed. The relative risk (RR) of SIs seemed to vary modestly with drug.TNFi treated RA patients in large observational studies have suggested an initial twofold increased risk of SIs compared with biologic-naïve patients. Long-term observational studies on the risk of SIs in patients treated with non-TNFi bDMARDs are sparse.This study aimed to estimate crude as well as age and gender-a...

RA patients receiving TOF 5 or 10 mg BID plus MTX showed sustained clinical and radiographic treatment effects through months 12-24. The safety profile was consistent with previous TOF studies. The 12-month data from the ORAL Scan study have been previously reported. This report assesses durability of responses, including structural damage progression, and safety with TOF through 24 months. Patients were randomized 4:4:1:1 to receive TOF 5 or 10 mg BID, or PBO advanced to TOF with stable, backgr...

This review shows that changes in lymphocyte subsets were largely within normal reference ranges and were not associated with efficacy or safety end points. BARI is a selective JAK1/JAK2 inhibitor, approved for the treatment of moderate to severe RA. BARI treatment is associated with changes to circulating lymphocyte and lymphocyte subsets, however detailed analyses of these effects, and their relevance to efficacy and safety is lacking. This study investigated the changes in lymphocyte cell sub...

Occurrences of venous thromboembolism (VTE) in 50, 865 RA patients initiating Tofacitinib (TOF) or a TNF inhibitor (TNFi) was infrequent. No significant risk of VTE for TOF versus TNFi was observed.Safety concerns of JAK inhibitor BARI include potentially increased risk of VTE at the higher 4 mg dose. It’s unclear if this is attributable to JAK-inhibition and extends to TOF. This study compared the risk of VTE with TOF, versus TNFi in real-world settings with RA patients.RA patients initiating T...
