PLACEBO-CONTROLLED EFFICACY AND SAFETY OF UPADACITINIB THROUGH ONE YEAR IN PATIENTS WITH NON-RADIOGRAPHIC AXIAL SPONDYLOARTHRITIS

BackgroundUpadacitinib (UPA), a Janus kinase inhibitor, was effective and well tolerated in patients (pts) with non-radiographic axial spondyloarthritis (nr-axSpA) through 14 weeks (wks) of treatment.[1]ObjectivesThis analysis assessed the efficacy and safety of UPA vs placebo (PBO) through 1 year.MethodsThe SELECT-AXIS 2 nr-axSpA study included a 52-wk randomized, double-blind, PBO-controlled period. Enrolled adults had a clinical diagnosis of active nr-axSpA fulfilling the 2009 ASAS classification criteria, objective signs of inflammation based on MRI sacroiliitis and/or elevated C-reactive protein, and an inadequate response to NSAIDs. One-third of pts had an inadequate response to biologic DMARDs. Pts were randomized 1:1 to UPA 15 mg once daily or PBO. Concomitant medications, including NSAIDs, had to be kept stable through wk 52. The study protocol outlined that pts who did not achieve ASAS20 at any two consecutive study visits between wks 24 to 52 should receive rescue therapy with NSAIDs, corticosteroids, conventional synthetic/biologic DMARDs, or analgesics. Cochran-Mantel-Haenszel (CMH) test with non-responder imputation incorporating multiple imputation (NRI-MI) was used to handle missing data and intercurrent events for binary efficacy endpoints. Mixed-effect model repeated measures (MMRM) was used to assess continuous efficacy endpoints. NRI was used for binary endpoints after rescue and as observed analysis excluding data after rescue for continuous endpoints. Treatment-emergent adverse events (TEAEs) are reported through wk 52.ResultsOf the 314 pts randomized, 259 (82%;UPA, n=130;PBO, n=129) completed wk 52 on study drug. More pts achieved an ASAS40 response with UPA vs PBO from wks 14 to 52 with a 20% treatment difference at wk 52 (63% vs 43%;nominal P <.001;Figure 1). The proportion of pts achieving ASDAS inactive disease with UPA remained higher than PBO at wk 52 (33% vs 11%;nominal P <.0001;Figure 1). Consistent improvements and maintenance of efficacy were also seen across other disease activity measures. Between wks 24 and 52, fewer pts on UPA (9%) than PBO (17%) received rescue therapy. A similar proportion of pts in each treatment group had a TEAE (Table 1). Infections were the most common TEAE;the rates of serious infections and herpes zoster were higher with UPA vs PBO, although no new serious infections were reported from wks 14 to 52. COVID-19 events were balanced between treatment groups. No opportunistic infections, malignancy excluding non-melanoma skin cancer, adjudicated major adverse cardiovascular events, inflammatory bowel disease, or deaths were reported. Two pts (1.3%) on PBO had adjudicated venous thromboembolic events.ConclusionUPA showed consistent improvement and maintenance of efficacy vs PBO through 1 year across multiple disease activity measures. No new safety risks were identified with longer-term UPA exposure. These results continue to support the benefit of UPA in pts with active nr-axSpA.Reference[1]Deodhar A, et al.

LONG-TERM EFFICACY AND SAFETY OF UPADACITINIB IN PATIENTS WITH PSORIATIC ARTHRITIS: 3-YEAR RESULTS FROM THE PHASE 3 SELECT-PsA 1 STUDY

BackgroundUpadacitinib (UPA) improved symptoms in patients (pts) with psoriatic arthritis (PsA) with prior inadequate response or intolerance to ≥1 non-biologic disease-modifying antirheumatic drug (nbDMARD-IR) through week (wk) 104 or 2 years of treatment in SELECT-PsA 1 [1].ObjectivesTo evaluate efficacy and safety of UPA vs adalimumab (ADA) through wk 152 or 3 years from the ongoing long-term open-label extension of SELECT-PsA 1.MethodsPts were randomized to receive UPA 15 mg (UPA15) or UPA 30 mg (UPA30) once daily, ADA 40 mg (ADA) every other wk, or placebo (PBO). At wk 24, PBO pts switched to UPA15 or UPA30. Following approval of UPA15, the protocol was amended so pts on UPA30 switched to UPA15 (earliest at wk 104). Efficacy was assessed through wk 152, and safety through June 13, 2022.ResultsOf 1704 pts randomized, 911 completed 152 wks of treatment. The proportions of pts achieving.≥20%/50%/70% improvement in American College of Rheumatology criteria (ACR20/50/70), minimal disease activity (MDA), and ≥75%/90%/100% improvement in Psoriasis Area and Severity Index at wk 152 were generally consistent with those at wk 1041. UPA had greater ACR20/50/70 and MDA responses vs ADA, and a greater mean change from baseline (BL) in Health Assessment Questionnaire-Disability Index, pt's assessment of pain, and Bath Ankylosing Spondylitis Disease Activity Index vs ADA. Change from BL in modified total Sharp/van der Heijde score were similar between UPA30 and ADA, and numerically higher with UPA15 (Table 1). The overall UPA safety profile remained unchanged (Figure 1) [1,2]. UPA had numerically higher rates of serious infection (SI), herpes zoster (HZ), anemia, lymphopenia, creatine phosphokinase (CPK) elevation, and non-melanoma skin cancer (NMSC) vs ADA. Increases for SI, HZ, anemia, and CPK elevation with UPA were dose dependent. Rates of major adverse cardiovascular events, venous thromboembolism, and malignancy excluding NMSC were low and generally similar across groups. The most common cause of death was COVID-19.ConclusionEfficacy of UPA in nbDMARD-IR pts with PsA was maintained through 3 years of treatment. No new safety signals were identified.References[1]McInnes IB, et al. Rheumatol Ther 2022;1–18 [Epub ahead of print].[2]McInnes IB, et al.

A case of feline gastrointestinal eosinophilic sclerosing fibroplasia limited to the mesentery.

An entire, female, mixed-breed cat of unknown age was presented with a 6-week history of lethargy, anorexia and vomiting. There was an increase in the number of white blood cells in the blood, including neutrophils and eosinophils; moderate anaemia; ascites; and possible mesenteric peritonitis. Exploratory laparotomy revealed firm, multifocal small nodules in the mesentery. As the nodules were surgically unresectable, they were biopsied. Histologically, the nodules were composed of thin trabeculae of dense collagen fibres mixed with plump fibroblasts and numerous eosinophils, consistent with feline gastrointestinal eosinophilic sclerosing fibroplasia. Bacteria were not detected on histological examination of the nodules and cytology of the ascites. Remission of disease occurred following treatment with prednisolone and ciclosporin A for 22 days and antibiotics for 40 days. After remission, ciclosporin A was administered for 236 days and then discontinued. Eosinophilia also resolved after treatment with ciclosporin A. The cat is still alive and in good condition on day 689. This report describes what may be an atypical case of feline gastrointestinal eosinophilic sclerosing fibroplasia, lacking involvement of the gastrointestinal tract, and was apparently cured by treatment that involved ciclosporin A.
