Show moreObjective. To report safety and efficacy of ixekizumab (IXE) from the COAST program at 3 years, including 1 year from the originating studies (COAST-V, COAST-W, and COAST-X), and 2 years from COAST-Y.Methods. In COAST-Y, patients continued with the dose received at the end of the originating study at week 52: 80 mg IXE either every 4 weeks (Q4W) or every 2 weeks (Q2W). Placebo-treated patients from COAST-X received IXE Q4W in COAST-Y. Starting at week 116 (week 64 of COAST-Y), patients receiving IXE Q4W could be escalated to Q2W. Safety for patients receiving >= 1 dose of IXE and efficacy for patients receiving >= 1 dose of IXE Q4W was assessed. Data are summarized as observed.Results. For the 932 patients who received >= 1 dose of IXE (Q2W or Q4W) through 3 years, treatment-emergent adverse events (TEAEs) occurred at an incidence rate (IR) of 38.0 per 100 patient-years (PYs). The most frequently reported were infections (IR 25.7 per 100 PYs) and injection site reactions (IR 7.4 per 100 PYs); the majority of TEAEs were mild or moderate in severity. In total, 7.1% of TEAEs led to discontinuation (IR 3.1 per 100 PYs). All patient groups receiving IXE Q4W assessed through 3 years saw sustained improvements in Ankylosing Spondylitis Disease Activity Score, clinically important improvement, and other efficacy end points.Conclusion. The 3-year safety profile of IXE in the COAST program is consistent with the previously established long-term safety profile. IXE Q4W provided sustained improvement of disease activity in patients who received treatment through 3 years.

Show moreObjective. This study evaluated the effect of ixekizumab (IXE) on self-reported functioning and health in patients with radiographic axial spondyloarthritis (r-axSpA) who were either biological disease-modifying antirheumatic drug (bDMARD)-naive or failed at least 1 tumor necrosis factor inhibitor (TNFi).Methods. In 2 multicenter, randomized, double-blind, placebo-controlled, and active-controlled (bDMARD-naive only) trials, patients with r-axSpA were randomly assigned to receive 80 mg of IXE [every 2 weeks (Q2W) or every 4 weeks (Q4W)], placebo (PBO), or adalimumab (ADA; bDMARD-naive only). After 16 weeks, patients who received PBO or ADA were rerandomized to receive IXE (Q2W or Q4W) up to Week 52. Functioning and health were measured by the generic 36-item Short Form Health Survey (SF-36) and the disease-specific Assessment of Spondyloarthritis international Society Health Index (ASAS HI). Societal health utility was assessed by the 5-level EuroQol-5 Dimension (EQ-5D-5L).Results. At Week 16, both doses of IXE in bDMARD-naive and TNFi-experienced patients resulted in larger improvement in SF-36, ASAS HI, and EQ-5D-5L versus placcbo. For SF-36, the largest improvements were seen for the domains of bodily pain, physical function, and role physical. A larger proportion of patients reaching improvement in ASAS HI >= 3 as well as an achievement of ASAS HI good health status was reported in patients treated with IXE. Improvements were maintained through Week 52.Conclusion. IXE significantly improved functioning and health as assessed by both generic and disease-specific measures, as well as societal health utility values in patients with r-axSpA, as measured by SF-36, ASAS HI, and EQ-5D-5L at Week 16, and improvements were sustained through 52 weeks.

Show moreOBJECTIVE\nTo determine whether a multibiomarker disease activity (MBDA) score predicts radiographic damage progression in the subsequent year in patients with early rheumatoid arthritis.\nMETHODS\nThere were 180 serum samples available in the BeSt study (trial numbers NTR262, NTR 265): 91 at baseline (84 with radiographs available) and 89 at 1-year followup (81 with radiographs available). Radiographs were assessed using the Sharp/van der Heijde Score (SvdH). Twelve serum biomarkers were measured to determine MBDA scores using a validated algorithm. Receiver-operating curves and Poisson regression analyses were performed, with Disease Activity Score (DAS) and MBDA score as independent variables, and radiographic progression as dependent variable.\nRESULTS\nAt baseline, MBDA scores discriminated more between patients who developed radiographic progression (increase in SvdH ≥ 5 points) and patients who did not [area under the curve (AUC) 0.767, 95% CI 0.639-0.896] than did DAS (AUC 0.521, 95% CI 0.358-0.684). At 1 year, MBDA score had an AUC of 0.691 (95% CI 0.453-0.929) and DAS had an AUC of 0.649 (95% CI 0.417-0.880). Adjusted for anticitrullinated protein antibody status and DAS, higher MBDA scores were associated with an increased risk for SvdH progression [relative risk (RR) 1.039, 95% CI 1.018-1.059 for baseline MBDA score; 1.037, 95% CI 1.009-1.065 for Year 1 MBDA score]. Categorized high MBDA scores were also correlated with SvdH progression (RR for high MBDA score at baseline 3.7; low or moderate MBDA score as reference). At 1 year, high MBDA score gave a RR of 4.6 compared to low MBDA score.\nCONCLUSION\nMBDA scores predict radiographic damage progression at baseline and during disease course. Show less
